The top agenda item for many climate activists (James Hansen, for example) is stopping the construction of new coal-fired power plants. Coal is the most carbon-intensive fuel, and the carbon dioxide (CO2) emissions from new coal plants at various planning stages could swamp by as much as 5 to 1 all the emissions reductions the European Union, Russia, and Japan might achieve under the Kyoto Protocol. Either climate activists kill coal, or coal will bury Kyoto.…
Continue ReadingThe wisdom of the ages applies to energy. The smartest-guys-in-the-room approach to energy transformation by DOE secretary Stephen Chu, based on a false premise of the unsustainability of hydrocarbon energy, should note such history. The silver bullets that he is looking for have a long, failed history for good reason.
Take for example the electric car,…
Continue ReadingThe debate about the environmental impact of ethanol rages on. Last month, the most recent study on the greenhouse gas (GHG) emissions associated with ethanol use was published by researchers from the University of Nebraska (Liska et al.). That analysis used the most recent data available on individual facility operations and emissions, observed corn yields, nitrogen fertilizer emissions profiles, and co-product use; all of which prove important because of improved energy efficiencies associated with ethanol production over the past several years. The authors found that the total life-cycle GHG emissions from the most common type of ethanol processing facility in operation today are 48-59 percent lower than gasoline, one of the highest savings reported in the literature. Even without subtracting-out the GHG emissions associated with ethanol co-products (which accounted for 19-38 percent of total system emissions), ethanol would still present GHG advantages relative to gasoline.…
