Still won’t be blogging regularly for awhile because of computer problems, but I did promise the rest of this review so here it is. Hi to all the friends old & new I met at KMWorld in San Jose this week.
This is the second part of a two-part review of George Monbiot’s book Heat. In the first part I explained Monbiot’s argument that a carbon rationing system was needed – that voluntary, technological and free-market solutions were not viable. Absolute caps in total carbon emissions, 90% less than current emission levels, need to be accepted in every sector of the economy. To the extent new technology reduces emissions they are welcome, but one way or another, by 2030, we must be releasing no more than a tenth of the carbon into the atmosphere that we are releasing now.
Monbiot explains three paradoxes that profoundly affect conservation behaviours:
The first specific area that Monbiot applies his rationing scheme to is home construction. He says the following regulatory changes are needed to achieve 90% reduction in home energy consumption:
One of the challenges we face is the huge variability in demand for electricity by season, time of day and other factors, and the need to have production capacity ‘reserves’ to accommodate spikes in demand quickly. His solutions to this problem:
Theoretically, he says, we could produce all the electricity we need, with 90% less carbon emissions, with a combination of scrubbed natural gas burning generators and wind energy from high-wind regime areas transported through high voltage direct current lines. The problem, though, is that most of us heat our homes with furnaces that burn hydrocarbons, not electrically. The solution to this, he argues, is to install the new generator technology (similar to that now used to power submarines) that produces heat and electricity at the same time. Greenpeace has developed a proposal to use these generators in winter, and switch to solar heating in summer (when home heating is not needed and the sun is stronger). But to reduce the carbon from the furnaces, we would need to convert to hydrogen-burning furnaces or hydrogen fuel cells in our home heating and electrical systems. So the complicated solution, he says, is:
A micro-generation system using solar panels and either hydrogen furnaces or hydrogen fuel cells would supply home heat and electricity. Either they could make their own hydrogen from electricity supplied by the grid, or obtain it from a pipeline network…Everything comes on and goes off at the flick of a switch, and works as smoothly as our heat and electricity systems do today. Around half of our grid-based electricity could be supplied by means of a few very large power systems burning methane, either in the form of natural gas or the effluvium from underground coal gasification [the only way to employ coal cleanly, he argues], and burying the carbon dioxide they produce. The other half, if my meta-guess is correct, could be provided by offshore wind and wave machines [carried by high voltage DC power lines].
In the process of coming up with this solution, he reluctantly rejects as impractical or naive three technologies that many environmentalists embrace:
He then turns his attention to the transportation system, another great carbon producer. He points out the irony that the faster cars travel on an expressway, the fewer cars the expressway can simultaneously accommodate (because of the need to provide greater stopping distance between the cars). So the 118-mile long, 6-8 lane UK M25 expressway can accommodate 53,000 car passengers (with an average occupancy of 1.6/car) traveling at 30 mph, but only 19,000 passengers traveling at 60 mph. If all cars were replaced with buses, it could accommodate 260,000 passengers at once. His answer, then, is to convert existing expressway lanes to bus-only lanes, operate high-amenity buses (spacious, comfortable seating, work-stations, food, beverage and media services) and run them, not in the cities, but in the suburbs and country, from the peripheral subway and LRT stations of the cities outward. Combined with carbon capping and rationing, and capping and rationing of road space, he argues that this could reduce auto emissions by 90% with no significant drop in convenience, comfort or transportation speed.
What could make the system even better, he argues, would be the use of imagination and innovation in transportation system design and options – new technologies like cellphones, GPS, vehicle tracking and smart tagging could offer exciting and efficient new ways of getting from A to B without major new investment.
While hydrogen is feasible in home power generation, it is not feasible, at least not in the 2030 time horizon, for powering automobiles and other hydrocarbon-based transportation, he argues. This argument, like those he makes against micro wind turbines, off-grid energy internets and biofuels, is complicated – too much so to meaningfully appreciate without reading how Monbiot made the long journey from enthusiast to skeptic on these technologies, in his own words. He’s also dubious about the limits of telecommuting and home-based enterprise – while he certainly encourages these developments as energy conserving, he makes a compelling case that less than 20% of work trips could practically be eliminated by them.
He offers no solutions to reducing air travel emissions by 90% short of grounding 90% of flights – he reviews and dismisses each of the popular ideas for making air travel more efficient or less polluting. A single London-to-NY round trip flight would exhaust a person’s entire 1.2 tonne annual budget for transportation emissions under Monbiot’s rationing scheme.
His solution to reduce the extravagant amount of carbon that comes from retail operations is simple – all stores whose customers reach them principally by private vehicles would be forced (by the limits of the rationing scheme or by direct regulation) to convert to online warehouse-based delivery-to-home operations. Savings would accrue not only from reduced electricity and square footage but from saved customer fuel and reduced need for packaging. Of all his solutions, I think this is the most problematic. George doesn’t appreciate that going to the mall is a social experience now embedded in western culture, not just a method for buying stuff. His suggestion for replacing the highly-polluting Portland cement and concrete production process with geopolymeric cements, which is also squeezed into the penultimate chapter, is far more compelling.
The book’s final chapter deconstructs the arguments that new fuel technologies or new carbon scrubbing technologies will save the day by 2030. “To succumb to hope of this nature”, he says, “is as dangerous as to succumb to despair.” Monbiot loves technologies and has studied dozens in the search for the easiest way to meet his 90% target, and in the process learned much about the discovery and commercialization curve, even when it is accelerated by urgency. Likewise, he dismisses the argument that the economic and fuel-consumption crash that Peak Oil will precipitate will solve the problem for us. It will actually make it worse, he says, as governments yield to the temptation to reintroduce dirty coal and other environmentally devastating fuels to stave off massive shortages and spiralling prices. He also dismisses those who would rely on “the market” to automatically self-correct our insatiable hunger for energy. “Buying and selling carbon offsets is like pushing the food around on your plate to create the impression you have eaten it”, he says. What is needed is absolute, immediate, equitable and universal reductions in emissions, and this cannot be done without regulation and rationing.
The problem, of course, is that regulations require governments with the courage to enact and enforce them. It took a horrific and unprecedented depression to push even the enlightened administration of FDR to switch from a laissez-faire to a highly regulated modus operandi. By the time the impacts of global warming hit home (and they will punish the disenfranchised and powerless poor of the world first) it will be too late. Monbiot concludes his book by trying to convince us to get off our collective butts, stop reading and chatting about the unfolding crisis, and do something. But his prescription is mostly actions for government, and we know too well how little our collective citizen/consumer voice counts in the minds of governments wined and dined and bribed to do the exact opposite by the most wealthy, powerful and organized corporatist lobby in history.
The ultimate irony of Heat is that his prescription is probably the only one that can save this planet from the scourge of global warming, but that, as simple, direct and painless as it is, this prescription has about the same likelihood of actually coming about as a snowball’s chance in hell. Or, perhaps I should say, a snowball’s chance on Earth after Monbiot’sbrave, well-researched, and ingenious ideas have been forgotten.
