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.
About 29 percent of the solar energy that arrives at the top of the atmosphere is reflected back to space by clouds, atmospheric particles, or bright ground surfaces like sea ice and snow. This energy plays no role in Earthâs climate system. About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface.
