The gradual change in the energy consumption pattern of the United States from 1860 to 1990. In the mid-1800s, biomass, principally woody biomass, supplied over 90% of U.S. energy and fuel needs, after which energy biomass consumption began to decrease as fossil fuels became the preferred energy resources. For many years, a safe illuminant had been sought as a less expensive substitute for whale oils. (more…)

In 2006, total world wind generating electricity capacity was around 72,000 MW, producing some 160 terawatt-hours (TWh) per year of electricity. As of the end of 2006, the top wind producers were Germany, with 20,622 MW; Spain, with 11,615 MW; and the United States, with 11,575 MW.
Even so, wind accounts for only about 1 percent of the world’s total energy use. (more…)
