...remained flat for the past 30 years. The energy efficiency campaign began in 1975 with refrigerators; today, says Garfield, there are more, larger models and they use approximately one-quarter of the energy as before. California's per capita electricity consumption has remained constant at approximately 7,000 kilowatt-hours while the rest of the United States has increased 40 percent or roughly 12,000 kilowatt-hours per person...
...EREV testing process, like the one that California's Air Resources Board (ARB) uses, may not actually measure gasoline usage at all but rather kilowatt hours per 100 miles, or kWh/100m. That figure is converted into miles per gallon, which effectively makes miles per gallon irrelevant...
...says the EPA will weight plug-in electric vehicles as traveling more city miles than highway miles on only electricity, presumably figuring that people buy electric cars primarily for local driving. GM expects the Volt to consume 25 kilowatt hours per 100 miles of city driving. At the U.S. average cost of electricity (approximately 11 cents per kWh), a typical Volt driver would pay about $2.75 for enough electricity to travel 100 miles, or less than 3 cents per mile. (Conversely, a gasoline-powered car that gets 20 m.p.g., for which the driver pays $3 per gallon...
...turning out to be way more expensive than originally advertised. The plants are cheap to operate, but unbelievably costly to build; estimates for new plants have doubled and even tripled over the last year or two. One recent study priced new nuclear generation at 25-30 cents per kilowatt-hour; new wind power comes in around 7 cents, about the same as coal, and investments designed to reduce electricity consumption through more efficient appliances, lighting or buildings cost about 1 to 3 cents per kilowatt-hour saved. This is why nobody on Wall Street or Main Street or any private...
Though Harvard has participated in the competition for several years, the Challenge’s emphasis on the number of green kilowatt hours of power purchased is not fully compatible with the University’s current energy-saving tactics...
