A new Rand Corp. study shows as much 25% of U.S. energy may come from renewable sources by 2025 at little or no extra expense.
The study credits ethanol's falling prices, wind power, and other renewable energy sources for the predicted increase in renewable energy use. Democrats in Congress and the Bush administration agree on supporting renewable fuels to replace oil, which bodes well for policies backing renewable energy.
The National Academy of Sciences will soon release an energy report that suggests wood chips may be an up-and-coming source of ethanol and electricity for industrial nations such as the U.S. and China.
China's government will begin supporting the development of biofuels through subsidies and tax incentives, the Ministry of Finance says. China's vice minister of finance, Zhu Zhigang, says the aim of these measures is to help rural economies, protect the environment, and relieve China's dependence on oil.
