The Obama administration hopes to make solar power more accessible for low- and middle-income Americans. It's announcing a series of moves, including installing more solar energy units in federally subsidized housing, low cost loans for homeowners and a program to help renters.

The White House recently pledged that the U.S. would get 20 percent of its total electricity from renewable sources by 2030, about three times what it does now. The Washington Post reports the administration is concerned about what might be called energy inequality:

" 'It's very important not only that we achieve that goal, but how we get there as well,' noted Obama senior adviser Brian Deese on a media call. 'We know there are significant challenges in the scope and geographic reach of solar.'"More and more voices of late are airing concerns about equal access to solar energy. 'The rapid decline of solar panel costs in recent years has ushered in a solar boom that has not spread uniformly across the spectrum of U.S. household incomes,' notes a recent paper from the George Washington University Solar Institute. 'Despite being more vulnerable to energy costs, lower income Americans have lagged behind more affluent households in adopting solar and realizing its numerous benefits.' "
