If President-elect Barack Obama’s choices for officials to deal with energy and environmental issues are any guide, development of coal technology may lag during his administration. Obama has announced the following choices for top posts: l Steven Chu, a Nobel Prize-winning physicist, for secretary of energy. Chu heads the enormous Lawrence Berkeley National Laboratory. Under his leadership it has emphasized research on biofuels and solar energy. Chu reportedly believes a massive shift away from use of fossil fuels such as coal is essential to fight global warming. l Lisa Jackson to head the U.S. Environmental Protection Agency. Jackson formerly was chief of the New Jersey environmental agency. New Jersey has been among East Coast states attacking coal-fired power plants. l Carol Browner, who served as EPA chief during the Clinton administration, to be a coordinator for energy and climate change issues.
