More than 150 years ago, wood, which is one form of biomass, supplied up to 90 percent of our energy needs. Today, we are looking again at renewable resources to find new ways to use them to help meet our energy needs. Overall consumption from renewable sources in the United States totaled 6.8 quads BTU （quadrillion Btu） in 2007 or about 7 percent of all energy used nationally. Consumption from renewable sources was at its highest point in 1997, at about 7.2 quads. Over half of renewable energy goes to producing electricity. Renewable energy plays an important role in the supply of energy. Even with the current fluctuating prices for fuel, U.S. residents and businesses pay a significant price for their utilities. Emissions from the evaporation and combustion of these traditional fossil fuels contributing to a range of environmental and health problems, causing poor air quality, and emitting greenhouse gases caused global warming. The method of producing alternative energy from municipal solid waste plastic is considered an effective way to meet the demand of energy need and save the environment at the same time.展开更多
