According to a 2008 analysis by the National Renewable Energy Laboratory, supplying all of the United States’ electricity needs with photovoltaic solar energy would require roughly 0.6 percent of America's total land area or 1,948 square feet per person...
Today, solar energy provides less than one percent of the world's energy, but that share could grow considerably with the right public policies and continued price reductions.
According to the International Energy Agency (IEA), emissions-free solar technologies could provide one quarte
The most commonly utilized solar technologies use inert materials found at every building site including silicon (glass), aluminum (frame) and copper (wiring).
