These are critical times in the fight to combat global warming, and around the world countries are turning to renewable energy sources to provide clean electricity. This year, global wind energy production is set to top 300,000 MW, sparked by new major projects in Europe, the US and China. And Denmark, a country that is already 25 percent powered by offshore wind, is set to double its wind energy production by 2020. It isn't just wind energy that's making the headlines, though; a new study finds that the solar photovoltaic industry is set to pay off its energy debt and become a net energy producer by 2015, And this week, researchers set a new solar record for black silicon cells with an efficiency rate of 18.7 percent.
