Solar only accounts for a small 0.6% of U.S. electricity but since the mid-2000s, thanks mostly to Federal tax credits and cheaper (Chinese) panels, solar instillation radically increased (mostly in California). In 2017, the Federal tax credits expire and as Brad Plumer explains, U.S. solar photovoltaic growth might hit a serious speed bump, particularly for residential installation.

Will the solar boom be another false start–like the 1970s–or will the Federal government reinstate the subsidies before they expire in 2017? Will panels prices continue to fall, making unsubsidized or lower subsidies panels affordable? Will Obama's Clean Power Plan make the States pick up the slack? Question to be determined in the coming years.
