The European nation was the only country to get an A in Global Green's Global Solar Report Card; its A- grade was unchanged from 2008. California - which was rated independently of the U.S. - and Italy came in second and third, respectively, with grades of B and B-.
Spain, France, the U.S. and Japan shared C+ grades.
Poland and Russia got the two failing grades, due to their governments' lack of photovoltaic-specific incentives. But six nations improved from the 2008 ranking: Italy, Japan, Greece, China, the United Kingdom and Switzerland had better scores this year than last.
Matt Petersen, president and CEO of Global Green USA., said that "governments [need] to shift subsidies for oil, gas and coal toward solar and renewable technologies." The benefits, he said, are manifold: jobs will be created, people in need can be pulled from poverty and greenhouse gas emissions will be reduced. "The report card," Petersen continued, "enables us to see which countries still need to strengthen their solar programs."
