Solar energy is becoming a force to be reckoned with.
Last year, China and the United States installed a record 15 and 7.5 gigawatts (GW) of solar, respectively. This year, the world could install as much as 66 GW.In 2015, investors poured $161 billion of capital into solar, the largest amount for any single power source. In China, 43 GW of capacity have been installed, more than in any other nation; India aspires to build 100 GW of solar capacity by 2017. Across the sun-drenched Middle East, investment rose from $160 million in 2010 to about $3.5 billion in 2015.
