Book Review: Green Hell: How Environmentalists Plan to Control Your Life and What You Can Do to Stop Them by Steve Milloy (Regnery Publishing 2009)
Though this is not the normal perspective from which my information comes it is good to get varying perspectives, even if they are overly paranoid. This book is decidedly anti-green. In fact, every possible green agenda is debunked in some way. Quantitatively I would say that about 50% of the book is over-the-top anti-green paranoia, maybe 20% is seriously worth considering, and the other 30% has some plausibility. Many important issues about how we live and rules about how we live involve determining how such living and rules will affect the environment. These are not black and white issues and there is not a thoroughly compelling consensus on a lot of them as to what is best to do. Well organized ‘green’ factions with considerable lobbying power pervade all levels of politics nowadays, for good or ill. The greens are a force that cannot be ignored and in fact must be considered in detail. However, the political greens can be quite biased, especially regarding key policy decisions. Most of the disagreements about the environment are in terms of policy determination. The questions are often: What limits do we set? How much of this or that pollutant or greenhouse gas is acceptable? How should regulation proceed? What processes should be encouraged and subsidized and which should be discouraged and penalized? What is a fair way to go? Most of the answers are not simply and there are often questions and disagreements as to the certainty of the science.
Milloy paints the green agenda as one of restriction and regulation. He sees the greens as coercing our behavior to one of conservation, reduced comfort, and reduced hope. I guess he sees the sustainability movement as a conspiracy to take away our freedoms. What he doesn’t see is how our inefficiency and recklessness with the environment has already limited the freedoms of others. He notes that green activist groups are well funded, like National Resources Defense Council (NRDC), Environmental Defense Fund (EDF), nature Conservancy, Greenpeace, and even the more extremist Earth Liberation Front (ELF).
Milloy, of course, is very suspicious of the reality of global warming as well as of ideas that suggest limiting economic and population growth. He seems overly concerned with we losing our standard of living, having to conserve energy. He ridicules Paul Ehrlich’s Population warnings in his 1968 book “The Population Bomb” which never came to pass- not even close. He talks about the greens politically playing on “green guilt.” I think his main concern is that he does not like being told what to do by what he perceives as a left-leaning political faction and he does have some good points there. It is all about what policies will prevail and who gets to set them. He sees reducing one’s carbon footprint as reducing economic growth and in terms of the “old” system he is right, but a new system is slowly becoming more apparent as conservation and waste reduction also mean growth – doing the same with less. He criticizes the “shadiness” of the carbon offset market promoted by Al Gore in “An Inconvenient Truth.” He criticizes current carbon trading markets and rightly so as at the early ones in
did not work as planned and inadvertently benefited certain corporations. He
sees the greens as a “Big Brother” aspect, especially in regards to proposals
of mandatory waste reduction but taxes on consumption will probably be the
eventuality. “Smart growth” and rationing will be incentivized more and more as
fossil fuel supplies eventually dwindle and prices rise, at least after the
current surge of resource availability slows down. Many are getting a jump on
things now before full scale global warming effects kick in. While he
successfully rails against Ehrlich’s blundered predictions of population growth
and its implications, such growth is still most certainly taxing the earth and
its resources. What he does not mention is that voluntary population reduction
has occurred in several countries with educated and reasonably wealthy
populations and women’s rights. These three: education, economic opportunity,
and perhaps especially, women’s rights, are very important in this regard.
Many green factions campaign against the use of fossil fuels so much that any possible delaying or hindering of development is considered a victory. Some fossil fuel projects may be more potentially polluting than others but often the science is not clear-cut and much influenced by propaganda. Lawsuits from environmental groups can tie up projects for years, costing corporations heavily. Opposition to oil, gas, and coal development can mean that the U.S has to rely more on OPEC and imports, though this has not been the case in recent years due to the efficacy of shale gas (and oil) development. New refinery capacity has successfully been blocked by green groups, mainly due to unacceptable emissions levels of NO2. He complains about the expenditures (in the tens of billions) refineries have to make to comply with the Clean Air Act, and many other statutes. Perhaps if he had to live next to a refinery and have his family’s life shortened, he might think otherwise. New coal power plants have been opposed and now finally many of the oldest and dirtiest are being phased out, along with their pollution and greenhouse gas emissions. But greens have also opposed natural gas, the cleanest of the fossil fuels, as just as undesirable. Basically, it is a war against fossil fuels. But they also oppose nuclear energy and many have campaigned against wind farms – claiming that they destroy scenery. Potential wildlife habitat destruction has also been implicated in opposition to wind and solar projects. One acknowledged blunder of greens is that biofuels often cause as much or more ghg emissions as fossil fuels over the whole cycle of the process.
Milloy sees a “hidden agenda” of green policies, stating their goals as: “zero population, limiting the development of physical infrastructure, impeding economic growth, and redistributing wealth.” He also seems to think most of our energy problems are due to regulations. Both are rather paranoid assumptions. He sees greens as promoting the expansion of government and of government power over the people. He quotes George Will when he equated environmentalism with collectivism and suggested environmentalists really had an ideology agenda. While I am sure that some do have such agendas, I think Milloy’s and Will’s notion that environmentalists as a whole have a coherent plant to produce scarcity is rather ridiculous.
He presents a chapter on the issue of car usage – gas taxes, congestion fees, promoting walking/biking/mass transit, etc. He says the greens promote road usage fees in a bid to get more cars off the road through the means of driving up the cost of driving. Reduce driving by making it more expensive. It is a form of taxing/feeing consumption. This is undeniably true but the money goes for better infrastructure and sometimes such scenarios can relieve congestion, parking, and overusage. He tackles the economics of hybrids and concludes that the payout is slow. Of course, it depends on how much one drives. For me, as a long driver, my hybrid paid out excellently – After 5 or 6 years, the gas $ savings over my previous vehicle (SUV) actually paid for the vehicle. He rallies against improving CAFÉ standards for mpg in cars and trucks with the observation that the best method for doing so is making vehicles lighter, which also makes them less safe in crashes. Of course, safety improvements in lighter vehicles should be pursued as well. He notes that greens also typically oppose highway expansions. Proposed light rail projects have been both promoted and proposed by greens for various reasons.
Next, he tackles water conservation. It should be noted that this is a regional issue – some areas have abundant freshwater, while others don’t. Chlorination of water supplies has saved lives but has also been criticized as being toxic. Tapwater is generally not trusted these days and I have lived in places where it was barely drinkable. Bottled water is equally derided by greens due to the toxicity and disposal of the plastic bottles. Better to filter at home or buy large containers of filtered water, though tapwater, and occasional bottled water are fine, methinks.
He also criticizes vegetarianism/veganism, eating locally, and the slow food movement. He rails against limiting pesticides as well, saying that they are safe at legal levels – but we all know they are dangerous at higher levels and accumulate in the soil and the bodies of human and animals. They also pollute ground, groundwater, surface water, and the ocean. These substances are designed to kill. He makes some comments against organic food, saying it is not more nutritious, that cows and chickens raised organically use more land and have more emissions that factory farms, and that chemical fertilizer use makes for greater yields on less land. What he doesn’t mention is that soil depletion is more of a problem in conventional farming. I don’t buy the argument that organic livestock has more emissions, though there may be a bit more runoff to streams. He also promotes biotech and GMOs as vastly increasing yield per acre, esp. of cotton, corn, and soy, most of which all three are now GMOs.
The section on health and safety is interesting. Often, there are tradeoffs when eliminating one dangerous thing in favor of others. After DDT was banned, more children died of malaria transmitted by mosquitoes than before. Removal of chlorine from a water supply in
may have been responsible for
10,000 deaths and a million illnesses. Bicycle usage may result in more
accidental deaths than car usage. Removal of asbestos fire retardant may make
structures more flammable. He gives an interesting account of what can happen
when one breaks a compact fluorescent light bulb (CFL). These contain mercury
and can be dangerous when broken. The recommendations for safe disposal are
rather extensive. They are also supposed to be recycled – which we do. I had
one break in the basement but just got it cleaned up quick – unaware that the
mercury was potentially as dangerous as it is. Green campaigns against fire
retardants may make houses more flammable and burn faster. Removing dead and
damaged wood from areas prone to forest fires to limit fuel for potential wild
fires has been regarded by environmentalists as a pretext for logging. He
repudiates the link between mercury and autism, though now the
mercury-containing thimerosol is no longer used in vaccines. He gives a blurb
also on the prospects of “geo-engineering” – putting aerosols like dust or
sulfate particles in the atmosphere to cool the planet – Bill Gates is actually
working on such schemes – or adding iron to the ocean to encourage the growth
of CO2-removing plankton. He notes that some effects of this may be unknown and
could go awry. Peru
In a section about greenism as “Big Brother”, the author notes the abhorrence given to so-called global warming deniers, with calls to hold them publically accountable. While I have studied climate for some time and agree that climate change is a very large potential problem, it is by no means clear how, how fast, when, and where things will play out and policy issues are still very much debatable. He speaks of green government micro-regulating our lives.
Milloy parodies green-ism to seem much like a cult where people are indoctrinated by the key messages of the movement. Of course, that could be said for any movement. Basically, I think he is saying that they are promoting their biases as official doctrine, or perhaps they are providing a clear message with clear scenarios that can be easily followed. Of course, the exact same thing can and has been said of global warming skeptics. He points to what I call “greener-than-though” attitudes and the good/bad dichotomy of seeing various factions as saving or harming the earth. The truth is we are all harming the earth and we all can help save or heal it. He also goes on about the invasiveness and inconvenience of things like garbage and recycling rules.
He has a section on the invasiveness and harshness of environmental law, referring to some EPA Clean Water Act enforcements of inadvertent wetlands disturbances in the 1990’s. He depicts EPA enforcement (some of whose agents are armed) as a kind of green police force. He says laws can promote “green vigilantism” though most of such things do little damage.
Also mentioned (parodied, criticized) are various “eco-monks” (those who live on little), the eco-elite – rich people whose jet-travel carbon footprint alone dwarves the entire footprint of most humans, and the land-grabbing business tactics of groups like the Nature Conservancy. He picks on the easy targets like Al Gore, Robert F. Kennedy Jr., and Richard Branson. Google and Arnold Schwarzenegger are others. He also criticizes T. Boone Pickens’ wind energy plan which was all but shattered by increased supply and lower prices of natural gas. Of course, he blames green conservation policies and regulation as driving up the cost of energy – but money does need to be spent to mitigate pollution and ensure safety. He also rails against green CEOs and green lending guidelines.
He rightly criticizes the Kyoto Protocol as potentially giving certain countries such as France, who rely more on nuclear energy, and Europe as a whole, a competitive advantage over the
in terms of fuel prices. There
are other reasons too that the KP disfavors the U.S. and many environmentalists
have also acknowledged that such is the case. Developing countries like U.S. China and India
may also get an advantage but with current pollution problems in , the
benefits of regulation are beginning to become apparent. Notions of “global
governance”, promoted by some European heads of state regarding environmental
policies are also dismissed as biased against the China He even denies that the
banning of CFCs and the subsequent re-thickening of the ozone layer did any
real environmental good! U.S.
He rails against ideas of Corporate Social Responsibility (CSR) as being manipulated by green activism but most I think would disagree with that as his arguments are weak here. He also criticizes the “Equator Principles” adopted by several prominent banks to evaluate loans on the basis of potential social and environmental consequences and concludes that such ideas impede economic progress and profitability. Of course, it is much easier to make money by avoiding environmental regulations and mistreating employees and local citizens – at least in the short term, but backlashes to such inconsideration can eventually hurt profitability as well. Of course, he criticizes any company seeking to improve the climate at the expense of profits. He refers to environmental protection as a “luxury” most available in the context of free market economics. He mentions Paul Driessen’s dubbing of green policies as a form of “eco-imperialism”. He also criticizes the greening of the
the biggest single user of energy, even though many prominent military
strategists support the innovative energy conservation policies coming about. U.S.
He devotes a whole chapter to Obama, as the first green president and notes his endorsements by the League of Conservation Voters and the Sierra Club. While he strongly criticizes what he thought to be some of Obama’s early environmental proposals, these did not come to pass in such a way and Obama has been more guarded in approaching energy and environmental policies than he depicts. He is correct about Obama’s push to phase out coal-burning power plants, as many environmentalists concur that phasing out the dirtiest of fossil fuels when there are currently abundant cleaner and often cheaper alternatives (natural gas), is a good idea. His prediction that Obama’s policies would lead to higher electric prices has not come to pass. Milloy also advocates against developing a “smart grid” which he says would include “smart metering” or the government regulating electric usage, though that is unlikely. He is, of course, critical of Obama’s first-term push for “green collar jobs” that can’t be outsourced. He compares it to a Depression-era public works program. But over the last 5 years we have not been forced to “live small” as he suggests. Though he bitches about pollution abatement required by the EPA and statutes such as the Clean Air Act and Clean Water Act, it cannot be argued that these laws have not improved our air and water. He makes fun of efforts to make cellulosic ethanol. He derides efforts to green the bailout during Obama’s first term.
He notes that green policies can be economically debilitating, although in reality such things as the current focus on energy efficiency and recycling can payout quickly and quite well. He sees the alarmist (must act now) factions of global warming alarmism as coercive and rebels by debunking anything and everything. He believes the greens are very well organized, well-funded, and over-represented in government, though many greens think the opposite. He cites polls where green policies are not favored. He fears “sweeping governmental reforms” proposed by the greens but that is unlikely the way I see it. He sees all green policy as advocating Big Government. His notion that organic agriculture is more wasteful, less sustainable, and more fossil-fuel intensive than conventional agriculture, misses the whole point of organic farming – reducing soil depletion, eating food without pesticides and chemical fertilizers, crop rotation, etc. Though yield per acre may be better in conventional agriculture, it comes at a cost. He sees green buzzwords like “smart” and “optimum” as catchy, hard to disagree-with depictions that put detractors immediately on the defensive.
Milloy recommends anti-green grassroots activism. He tells a rather humorous story where he was eating ice cream at a Ben & Jerry’s and noticed their statement about dioxin – that no levels of it are acceptable. But knowing that some dioxin is released whenever any organic materials are burned, it is commonly in the environment all over the place. They had the level of dioxin measured in some of Ben & Jerry’s ice cream and found it to be 200 times the EPA safe level and presented their results at the Dioxin 2000 conference. I think the key point here is that clever soundbites and headlines about this or that harm are not always as they appear and many of these complex issues require much study and consideration, especially in determining which policies are best. He sees the greens as seeing themselves on a “higher moral plane” (again the greener-than-thou notion). Of course, he is in favor of expanded coal usage, tar sands, oil shales, and other of the dirtiest forms of fossil fuel. Perhaps he should go to
to the smoggiest cities where
inefficient coal-burning power plants without pollution-control devices are
shortening lives and starting to piss people off – if he wants to see how his
own vision would work. Milloy represents the formidable force of the anti-green faction with his junkscience.com. It may not be accurate much of the time but it is a balancing force against the potential runaway power of green policies, and one that should be taken into consideration. China
While this book may seem ill-informed and silly to some, it does raise many issues that we should consider. Many of these issues do not lend clear indications of what policies should be. Biased factions, both green and non-green, seem to get the most airplay but compromise, collaboration, and consideration of the views of others are important.

Book Review: Crossing the Energy Divide: Moving from Fossil Fuel Dependence to a Clean-Energy Future by Robert U. Ayres and Edward H. Ayres (
Publishing 2010) Kindle Edition Wharton School
I found this to be an excellent book which cuts to the heart of the matter of energy in sufficient detail. The approach is practical and realistic with each energy source examined and some good ideas about increasing energy efficiency and redesigning industries, utilities, houses, cars, power grids, and cities for the future. The authors are two brothers, one a physicist and economist, the other a journalist specializing in health and sustainability.
The first point they make is that energy is far more important to economics than is generally acknowledged. The authors contend that energy services are a major component of what drives the economy. The authors also acknowledge that the transition to renewable energy is likely to take several decades and is not currently as feasible economically or technologically as advocates have depicted. The question is what to do in the meantime. The authors suggest that we “radically reform our management of the existing, fossil fuel-based system …” so we can dramatically increase the amount of energy services we get per unit of energy. One method of doing this is capturing waste heat. The authors note that in 2005 two steel companies began doing this at two facilities. Their resulting generation of 190 MW from waste heat that year was more than the entire output of the solar photovoltaic industry.
The authors advocate an energy management strategy. They estimate energy efficiency in the
at a mere 13% (compared to 20% for ) and suggest that could be at
least doubled with existing technologies. It’s all about doing more work with
less energy. Such strategies do not require massive capital and often result in
savings to those who implement them. Ayres, along with Benjamin Warr, revealed
the Ayres-Warr growth model that showed how energy and work drive economic
prosperity along with capital and labor. They showed that “technological
progress” could be seen as “the increasing thermodynamic efficiency with which
energy and raw materials are converted into useful work.” This is fairly
straightforward and logical. Being efficient saves money. “Labor and capital extract energy; they don’t make it.” What they mean is that energy
is not a product of labor and capital but a prerequisite to economic activity. Japan
They mention three ‘disruptive phenomena’ that are irreversible: 1) post-peak oil where production will cease to outpace consumption (a point which we are near), 2) efficiency limits of old technologies based on fossil fuels such as the internal combustion engine and steam turbines, 3) escalation of climate catastrophes in the manner of storms, floods, droughts, wildfires, and sea level rise. Reduction of greenhouse gases, energy independence, and energy security are all stated
The authors talk about the difficulties in determining the risks or hidden costs of climate change and how aggressive we should be in mitigating its effects. Another issue they mention is the notion of ‘energy independence’ which has been touted as possible by such measures as drilling in the Arctic Wildlife Refuge or building more coal-fired power plants. They dismiss those ideas but note: “The path to energy independence lies in the institutional and legal structure of the
energy system, not under the
ocean bottom.” U.S.
(Although since the very recent unconventional shale gas and oil revolution, we are much closer to energy independence for the time being.)
The authors advocate energy recycling as a much more viable means of producing carbon-free energy quickly with available technology than renewables at present. In 2005 the nation’s recycled energy output was about 7 times its solar energy output. They say that current recycled energy is only about 10% of what could be produced. Using fossil fuel more effectively through ‘cogeneration’ – waste-heat recycling, ie. combined heat and power (CHP) is available to coking, smelting, refining, chemical processing, and carbon black producing industries. Natural gas decompression can also be converted into energy. These are far cheaper than solar PV technology and wind turbines at present. There are several ways to turn waste-heat into electricity in the various industrties. In addition to high-temperature heat and decompression in the above scenarios, there is also low-temperature heat. Electric power plants often waste such heat that could be used to heat houses.
Apparently electric power plants are very inefficient – avg. of about 33%. This efficiency has not improved in decades. Much of the inefficiency has to do with transporting energy over wires from centralized plants. Small de-centralized CHP applications (DCHP) – in places like universities, shopping districts, and apartment houses can be developed and can be very efficient. Decentralization simply means that the loss of power from transmission is eliminated. The problem is that such applications are often illegal in the
due to outdated laws that created the power monopolies. DCHP has been used
routinely around the world for a long time – ie. in so-called “district
heating” in dense city environments. The
benefits are obvious. U.S.
“If power and heat could be cogenerated in individual buildings in the United States while retaining connections to the grid, virtually all new additional capacity could be decentralized.”
The bottom line is that we could develop efficient carbon-free energy with existing technologies and save hundreds of billions of dollars. (The IEA acknowledges this). This would seem to be a no-brainer but politics and corporate interests have powers not easily relinquished.
Large centralized power plants use steam-generation which is old tech but newer small gas turbines and diesel engines have improved in efficiency and are more portable for decentralized uses. An added benefit is that waste-heat can be used locally where it is needed, as in individual buildings for space-heating. Jeremy Rifkin and many others have promoted the idea of lateral power and micro-power plants from renewables but the same can be done with existing fossil fuel technologies with drastic improvements in efficiency, and thus drastically lower emissions as well. Efficiency is about a third (33%) when calculating the energy of a barrel of oil equivalent to electricity at the meter. That is just the efficiency of generation and delivery. There is also end-use efficiency – how efficient the consumer uses the energy. An example given is that of an incandescent light bulb = 5% efficiency compared to a compact fluorescent light bulb = 15 % efficiency. If each is multiplied by the efficiency of generation/delivery (33%) the numbers for total efficiency are just 1.66% and 5%!
“If you add up all the different kinds of energy use in the
the overall efficiency just for producing useful work is around 13 percent” United States
Waste-energy recycling in the short-term offers a much better economic and feasible opportunity to reduce carbon emissions than do all renewables combined, even with new renewable capacity doubling every year.
Studies suggest that retirement of the most inefficient (and polluting) of the nearly 4000
centralized power plants and decentralizing all new capacity could ramp up efficiency
from the current 33% to 60%. That would be a vast improvement economically and
Economic theory, indicators, and economic well-being are discussed. The authors, like many modern economists, see the limitations and misleading nature of something like GDP being a good indicator. Immediate cost/benefits are typically favored over long term ones and not all economic activity is good or beneficial. Social and environmental well-being also need to be taken into account. Cooperation is required in these efforts.
The authors offer 8 “Main Girders of the
All can be begin to be implemented with existing technology and most offer
quick payouts: Energy-Transition Bridge
1) Recycling waste-energy streams – only about 10% of what can be done is being done, they estimate. This alone can provide up to 10% of our electricity needs.
2) Utilizing combined heat and power (CHP) – most of this potential is untapped and politically blocked. Decentralizing would be required.
3) Increasing energy efficiency in industrial processes and buildings – many untapped “double-dividend” opportunities here, they say.
4) Increasing energy efficiency in consumer end uses – this has been well-publicized and partially tapped in the form of hybrid cars, energy efficient appliances, compact fluorescent bulbs, multipane windows, but more potential.
5) Kick-starting the micropower revolution, or “rooftop” revolution – utility monopolies on power distribution are the main obstacle.
6) Substituting energy services for products – we don’t really seek energy but the services that energy provides, so that should be the focus.
7) Redesigning buildings and cities for climate change – all new construction and transportation need to be designed for maximum efficiency. Cities under threat from climate-generated events need to prepare.
8) Reforming fresh-water management strategies – poor water management wastes vast amounts of energy and much could be improved with investment in better and more efficient strategies and infrastructure.
One analysis (ACEEE in 2008) concluded that of energy-service consumption increases in the last 38 years energy-efficiency improvements accounted for ¾ while new supplies of energy only accounted for ¼. Efficiency improvements have been called the hidden energy boom. The bad news is that the efficiency gains are likely lead to greater economic growth which in turn lead to greater energy consumption. Population growth was also likely a factor in increased consumption but was not mentioned here.
The term for energy doing useful work is ‘exergy’. This is the correct way to define efficiency as some measures of energy efficiency can be misleading. In exergy terms our energy economy runs at about 13% efficiency. The authors give examples of several industrial energy-efficiency investments that paid off extraordinarily well and relatively quickly. Of course, these improvements also cut emissions. The authors think that many executives and politicians are confused about the vast possibilities of investing in energy efficiency – due to improper definitions of efficiency and possibly ideological and business-cultural reasons as well. Growth has been favored far and above efficiency but efficiency has arguably increased the economic viability of companies just as well. Lack of attention to company energy use and cost management may also be factors. Executive focus on market share and growth may even reduce overall profitability but still rewards management. Focus on mergers and acquisitions is an example – where evidence suggests that only a small percentage has increased value for shareholders. They mention the idea of ‘industrial ecology and one of its fundamental principles:
“An operation that mimics nature by recycling its waste – including its waste-energy streams – puts less waste into the environment.”
Oddly, many of these waste-reduction payoffs have been induced by government – either by the carrot of incentive or the stick of regulation.
The authors mention the Public Utilities Regulatory Policy Act (PURPA) of 1978, revised in 1992. This allows industries to produce power from their waste streams and sell it to utilities at prices determined by the utilities. But they still cannot sell it to other, closer, consumers or industries. Such price-fixing by utility companies has hurt things like net-zero metering for solar and wind power where excess production can be sold back to the grid at a utility-fixed price most often below their own energy prices (though I think things have improved in some states in the last few years). This also stifles the effectiveness of federally mandated increases of renewable power. Another problem with PURPA is that many states have tended to ignore it. The biggest hurdle is the restructuring of the power grid itself. Local independent producers of power can add to the grid and save money by having greater efficiency and less loss of energy meaning less carbon emissions. The coming (presumably) micropower revolution would likely drastically increase efficiency, increase reliability of power, and provide better distribution during peak-load times. Coal lobbies and interests have been a hurdle to local, distributed, decentralized micropower but that influence is likely waning as coal loses its electricity market share to natural gas. The advantages of decentralization are gradually becoming more apparent. Low-temperature heat utilization is an advantage of decentralization. Local power production has less T & D (transmission and distribution) costs and less redundancy (back-up power) costs. Centralized power plant power runs at 33% efficiency while localized power that utilized waste-heat can run at 50-80 % efficiency. The authors estimate that CHP could cut ghg emissions by 15-20% and that early IEA estimates of 4% were way low. Decentralization increases energy security by not providing big targets for massive power interruption by terrorists or natural disasters. Copper and metal theft would also be reduced. Such theft is a continuing problem –there was such a theft here a few days ago that resulted in power outages. The authors estimate 20-25 years for the full transition to decentralized power and optimized CHP utilization with trillions of dollars in savings over building more centralized power plants. Centralized power monopolies are protected by federal and state laws against others selling power, transmitting power, and government subsidization of this least efficient power production. The authors also note that power decentralization is practically inevitable as old centralized power plants depreciate and demand for electric power increases due to more and more plug-in electric vehicles.
Liquid fuels and the implications of a reduced-car future is the next subject. Gasoline powered motor vehicles are very inefficient with payload efficiencies as low as 1%. Hybrid and electric cars only increase it to 2-3%. Corn ethanol and bio diesel offer slightly less emissions but require much fossil fuel to make and make corn and soy prices rise. The “ethanol scam” has been extensively written about and various ‘energy return on investment’ (EROI) studies indicate that ethanol (and biodiesel) production use nearly as much energy as they create. EROIs for ethanol range from less than 1 (loss of overall energy) to the range of 1.29 to 1.65. Oil in contrast is 15 and in 1930 was about 100. There are other negatives to ethanol and biofuels as well: pollution, pesticide use and runoff, massive water use, using up valuable cropland, soil depletion, etc. Any gains would be marginal for corn or soy based biofuels. Cellulosic ethanol from wastes may be slightly better but technology is not yet mature. Bio-diesel offers a bit better scenario as diesel engines have a better fuel-burn efficiency (50%) than gasoline engines (27%) but they also put out more emissions, soot, and other particulates. Indeed, traffic congestion and exhaust pollution are major problems in cities. Bicycles have much potential as a mode of transportation in cities if the cities are designed for it. E-bikes, equipped with a battery possibly partially solar powered.
has 30 million e-bikes out of 450 million bikes. Access to a biking grid as
well as safety are big issues, esp. in the car-heavy areas of the U.S. Bike
sharing and car sharing also have urban potential. The success of hybrid
vehicles has changed the culture a bit. The authors predict that future
electric cars specifically for short urban travel will have less power, zero
emissions, and much greater efficiency than gas-powered cars or current
Airplanes use about 10% of transportation fuels in the
terms of passenger-miles each passenger uses the equivalent of driving a Hummer
alone to his or her destination. Hydrogen, liquefied natural gas, and
algae-derived biofuels offer possibilities for powering jets post-oil. Increasing
CAFÉ standards for jets as well as cars is one transition option. U.S.
Planning for climate change includes mitigation – reduction of greenhouse gas emissions and adaptation – preparation for situations that are likely already in motion such as storm surges, sea level rise, storm intensity, droughts, floods, and wildfires. Vulnerable areas near coasts had best have a plan. Superstorm
was a recent reminder. If cities are treated as ecosystems the planning for
their health and resiliency to endure catastrophic climate events is improved.
They mention congestion improvements such as the adoption of bus rapid transit
(BRT) systems. These systems of unimpeded bus routing can save time and energy
and cut congestion. Light rail systems are also having much success in this
regard in places like Houston and Charlotte. Such transportation systems are
also cutting emissions and will improve further as bus fleets convert to
compressed natural gas and plug-in electrics. Better building standards will
also help cities plan for climate change. Moving building electrical systems
above flood prone areas and having back-up solar and/or micropower plants can
also help. Sandy
New construction of “low-energy” houses utilizing better insulation and especially passive solar, have proven to save money. Such projects in
resulted in cutting energy costs below half of previous construction. In other
European countries the gains were even more dramatic. Retrofits won’t be as
good but may be more practical for some areas. The solar PV rooftop revolution
also looms on the horizon. More efficient cadmium-telluride solar cells can
save money but have to utilize rare elements (mined in Germany with
little regulation) and create toxic waste (including spent solar panels). There
is not enough of the stuff in the earth to matter but other thin-film
technologies show potential as well. China
Regarding the question of how to prepare and deal with disaster, they give the case of the town of
Illinois, south of . The town was destroyed by the St. Louis Mississippi River floods of 1993 and they decided to
rebuild on a bluff 400 ft higher and 2 miles away. Good choice since the floods
of 2008 would have destroyed the old town again. They rebuilt with energy
efficiency, sustainability, and renewables. The authors give four goals for
such rebuilding (and retrofitting): 1) Space-conserving development – less
sprawl, less heat-absorbing pavement, and shorter travel-times; 2) Public
transportation oriented – buses, subways, car sharing, and plug-in electric
vehicle can be designed into the mix; 3) Living space oriented – less car
traffic means less paved areas and more room for greenspace, biking and hiking
paths, etc; 4) Low-energy, low-emissions buildings – new design offers better
opportunities for this than retrofitting.
The availability of fresh water is another issue worldwide, though mainly in certain places where it is scarce. There is mention of “peak water” like peak oil. Water access issues and conflicts abound around the world. We depend on agriculture. Agriculture depends on fresh water. Energy extraction, industry, and especially power plant cooling depend on fresh water. One example is the Ogallala aquifer in the plains states. It is being depleted rapidly, mainly by irrigation. Newer power plants use a closed circuit system for water cooling which ties up more water. The older ones use a “once through” system that when released back into the environment can do local ecological damage, and it is also wasted heat. Pumping water, sometimes over mountains (as is required in some parts of the American west). consumes large amounts of electricity (6.9 % of electric use in
is for water delivery – 3% for the nation as a whole – 19+% is used for water
and sewer in ).
The authors advocate water management reform. Problems ahead in water
conservation include 1) desertification – often caused by deforestation and
overgrazing, 2) forest-fire cycling – massive amounts of water are used to
quench fires in dry areas, often year round, 3) salt contamination of fresh
water in coastal areas – aquifers are expected to turn brackish further
upstream from the coasts. Such scenarios require more pumping of water which
require more energy use. The authors note that: California
“The goal of water-management policy cannot realistically be to increase the supply. It must be to reduce per-capita water use in parallel with decreasing fossil fuel use.”
I might add that this is especially important in regions with scarce water resources.
Waste-water recycling is a big issue and is beginning to have a big impact. Power plants are increasingly using reclaimed water for cooling. Oil and gas operations are recycling “frack” water and some are using acid-mine drainage water in their ops which is a sort of double dividend. The biggest potential for conserving water (and thus energy) is in its biggest use – irrigation. Drip irrigation uses 30-70% less water. They note that in the
, 80% of
water use is for agriculture but only 7% of irrigated land uses drip
irrigation. Much of it is flooded and spray irrigated. Production of corn
ethanol uses massive amounts of water – 10,000 gal per gal of ethanol. This
equates to 42,000 gal per barrel in oil terms, magnitudes more than in oil and
gas operations. The cheapest new water supply in the coming years will likely
be recycling wastewater. U.S.
In discussing policy, the authors note the problems of ideology and NIMBYism. One thing they advocate is a change in the incentive system so that instead of selling commodities (oil, gas, coal) one sells final service (heating/cooling). Profitability would then be less tied to selling the most product, but more tied to selling the most service with the least expenditure of energy. This would require a fundamental shift in corporate business models. Indeed, it is the growth/productivism overly tied to company profits and stock market high-grading that leads to waste and lack of incentive to produce more with less since short-term growth is more profitable than investing in mid and long-term efficiency measures.
Markets cannot exist for environmental services or pollutants. No one really owns them and we all share in the benefits and costs. Government regulations have sought to protect the beneficial and deter, abate, and punish the malevolent. The authors advocate simplifying the often complex regulatory frameworks. This should appeal to both liberals, who tend to favor regulation, and conservatives, who tend to favor simplified government and regs. Industry generally hates the idea of a carbon tax but might do better with adhering to environmental and energy-performance standards. Some of the recent most progressive industry consensus has been in agreeing on best practices and adhering to goals beyond and ahead of regulatory requirements. The authors note the widely acknowledged failure of the early European “cap-and-trade” system. They suggest an emissions tax that would partially replace payroll and personal income tax and thus reward energy efficiency and emissions reduction.
Their policy priorities include encouraging all of their eight girders of the energy bridge: 1) Encouraging waste-energy recycling – if this can be done where excess energy can be sold at a fair price, that would be an incentive, but it would also reduce (likely temporarily) utility sales and profits. This would require changing outmoded laws (utility monopolies). This is de-regulation and encourages a free-market which theoretically should be attractive to conservatives. Utilities complain that this will weaken the grid – their grid – but the authors counter that reliability and uninterruptible power availability will keep the grid needed and new usage, especially from electric cars will take up the slack. If massive electric vehicle growth (esp. for lower power urban electric vehicles and e-bikes) can be accommodated without building new power plants, that would take a lot of carbon out of the environment. They also advocate rewriting PURPA for what I was intended to be: an incentive for free market competition in power production and distribution. A carbon tax or other incentives could favor zero-emissions production, especially since it theoretically would reduce climate change abatement costs in the future. This would incentivize power production from waste-heat, pressure-drop, and renewables. 2) Ramping up CHP – one policy suggestion is to mandate purchase of increasing amounts of DCHP as well as renewables (many states do this for renewables) and eliminate or drastically reduce “feed in tarrifs” charged by utilities – which would incentivize decentralized power production. Instead – perhaps the decentralized producers could finance and enable “smart-grids” tied into the main grid. 3) Ramping up energy efficiency in buildings and industrial plants – better incentives and ROI need to be found for efficiency. One possibility is charging more for excess electrical usage. Creation of “Energy Service Companies” (ESCs) who manage energy efficiency measures. The authors suggest a scenario where the company pays the ESC the same amount that they pay the utility, the ESC pays for efficiency upgrades and pays the utility bill(s) for a set amount of time and keeps the rest. Such a scenario might require the ESCs the ability to borrow at reduced rates (as a govt. incentive). After the set time period the savings would revert to the consumer. Time periods can be worked out based on initial upgrade costs and projected savings. They suggest making ESC investments tax free as an incentive that might attract venture capital. Another policy suggestion they mention is to establish a much simpler cap-and-trade system for carbon emissions. Their scenario would not use “offsets” or “grandfathering” but be an open market for producers of oil, gas, coal, ethanol, timber, and biofuels. This would increase their costs and the cost of energy to consumers. Downstream industries would not need permits. Benefits would come to individual taxpayers in the form of sellable permits with expiration dates in a fluctuating market. Thus the tax would be payable to people rather than governments and conservation would be incentivized even more. 4) Continuing efficiency gains in consumer end uses – strengthening CAFÉ standards to include maximum achievable mpg for all vehicle and airplanes as well. Incentivizing operating efficiency of products, maintenance, and disposal/recycling (by the manufacturer) are also recommended. The use of deposits for products encourages their return to the recycling stream. This can be a hassle for dealers and manufacturers though. Abandoned vehicles, appliances, and other equipment can be hazardous. Extended producer responsibility (EPR) policies encourage efficiency, recycling (which is cheaper than mining for metals), and durability. There is also incentive for the producer to optimize recycling potential under such scenarios. EPR supports “urban mining” as a profitable venture. 5) Decentralizing electricity production – rewrite PURPA and retire old dirty coal power plants by closing Clean Air Act loopholes. 6) Finding alternative ways to provide an energy service – esp. ways that conserve energy. Examples are telecommuting, internet shopping, biking or bussing instead of driving. Incentivize minimizing urban car use. 7) Redesigning cities – prepare for climate change contingencies, mandate energy-efficient new housing construction, develop evacuation plans, cost insurance with risk (usually flood risk) to encourage development on higher ground, and revise building codes in vulnerable areas. 8) Linking water management to energy management – goal is to reduce per capita water consumption. Water and energy consumption tend to exacerbate one another. Reducing one reduces the other. Ramp up drip irrigation. Utilize wastewater for power plant cooling.
The authors also give three recommendations for business managers and investors: 1) Bring energy management to the highest level of strategic planning – reducing waste simply saves money. It may not be the core business but it helps it. 2) Recognize the business opportunities, and risks, that will come with rising natural resource prices – reducing the cost of energy service becomes more consequential as fuel prices rise. Price rises seem to have been abated since the publication of this book with success in shale gas and oil and the very gradual move to a natural gas-based transportation economy. Oil and gas companies and utilities typically abound in capital which is a potential source of funding for new tech ventures in renewables and energy efficiency, even though energy efficiency was scorned in the past as hurting profits. 3) Get ready wherever you are -Perhaps a time of dual policies of producing energy and producing energy services is ahead for some of these companies. Costs of energy services and carbon footprints need to be part of business models. Timing is important as well. For example, if plug-in electric vehicles (EV) ramp up too fast, they may lead to building more coal plants, which would counter emissions reductions. Rapid buildup of EVs could also provide some storage capacity on the grid for solar and wind.
Waste-energy recycling opportunities are estimated at 65-95 GW, or 7-10% of
electric output, with no or very little emissions and much lower cost than
building new power plants. CHP plants produce 8% of U.S. U.S.
power compared to over 50% in places like Denmark,
though much of theirs is “district heating” which is mostly not applicable in
the spread-out U.S. CHP opportunities in the have been estimated at 135 GW,
also reducing emissions. Efficiency could be increased from the current 33%
from centralized power plants to 50% by mid-century with the addition of small
de-centralized fossil fuel plants. This could be increased further with the
addition of rooftop solar PV and wind apps. Investments in energy efficiency
are considered low-risk and moderate to high return and there is much
opportunity in industry, which represents 25% of electric use, and buildings,
which represents another 25%. End-use efficiency is a no-brainer for saving
money and for reducing emissions. It is estimated that end-use efficiency of
appliances, which represents 12% of emissions reduction potential over the next
4 decades, and better mileage standards for vehicles, which represents 24% (total
36%) offers a significantly greater emissions reduction potential than
renewables. Statistically, improvements in fuel economy offer vast emissions
reduction potential and should be pursued further. U.S.
The authors acknowledge that Al Gore’s 2008 suggestion that renewables can replace coal in a decade is unrealistic. We are halfway there and renewables have barely made a dent. It is clear that the ideas presented in this book offer much more in the near-term than renewables – although the authors agree that renewables should be more vigorously pursued.
This is certainly one of the best books about the future of energy I have come across so far.
