Donald Trump’s dream to bring back coal faces a huge barrier: the unstoppable decline of clean energy costs.

Now, analysis by Bloomberg New Energy Finance, combining knowledge of planned energy projects with economic forecasting, shows that they’re falling faster than ever.

By 2040, prices will fall 66 percent for solar, 47 percent for onshore wind, and 71 percent for offshore wind.

BNEF says that means 72 percent of the $10 trillion invested into energy by 2040 will be directed into renewables.

Obama might be right: the clean energy shift may be irreversible.
