China takes lead in clean-power investment

Reporting from Washington — China overtook the United States for the first time last year in the race to invest in wind, solar and other sources of clean energy, according to a comprehensive new report that raises questions about American competitiveness in a booming global market.

U.S. clean energy investments hit $18.6 billion last year, a report from the Pew Charitable Trusts said, a little more than half the Chinese total of $34.6 billion. Five years ago, China's investments in clean energy totaled just $2.5 billion.
