Renewable energy comes from a source that is not reduced when it is used. The sun, for example, continues to have the same amount of energy whether that energy is turned into electrical energy or not. In contrast, the supply of coal decreases when it is turned into electrical energy. The primary types of renewable energy in the United States are solar, wind, biomass, hydropower, and geothermal. The amount of energy supplied by each type of renewable energy from 2006 to 2016 is summarized in Figure 1, which also includes supply projections for 2017 and 2018. During which time interval did hydropower energy production increase? Question 4 options: 2009-2010 2010-2011
2011-2012
2012-2013
