Growth Of Global Solar & Wind Energy Continues To Outpace Other Technologies
Global use of solar and wind energy continued to grow significantly in 2012. Solar power consumption increased by 58 percent, to 93 terrawatt-hours (TWh), and the use of wind power increased by 18 percent, to 521 TWh. Although hydropower remains the world’s leading renewable energy, solar and wind continue to dominate investment in new renewable capacity and are quickly becoming the highest-profile renewable energy sources, write Worldwatch staff in the Institute’s latest Vital Signs Online trend.
Global solar and wind energy capacities continued to grow even though new investments in these energy sources declined during 2012. Global investment in solar energy in 2012 was $140.4 billion, an 11 percent decline from 2011, and wind investment was down 10 percent, to $80.3 billion.But due to lower costs for both technologies, total installed capacities grew sharply.
Solar photovoltaic (PV) installed capacity grew by 41 percent in 2012, reaching 100 gigawatts (GW). Over the past five years alone, installed PV capacity grew by 900 percent from 10 GW in 2007. The countries with the most installed PV capacity today are Germany (32.4 GW), Italy (16.4 GW), the United States (7.2 GW), and China (7.0 GW).
