Hawaii's utility-scale electricity generation from solar energy more than doubled in 2014. Hawaii generated 29% of its renewable electricity from both utility-scale resources and small-scale solar photovoltaic panels installed on rooftops across the islands. Hawaii is the first state to set a goal of producing 100% of its electricity from renewable energy sources. The state plans to reach that goal by 2045.
Hydroelectric energy is a very important energy source, both nationally and worldwide. About 19% of the world's total electricity production comes from hydroelectric energy and about 7% of the power in the U.S. When we look at hydroelectric energy for the U.S. in terms of renewable energy sources (so comparing this to things like solar power, wind power, geothermal energy and biofuels), it makes up 96% of renewable energy electricity production.
