How about a Kickstarter for buying coal plants and turning them off.
How about a KickStarter so more people can use more solar in some small capacity, thus reducing our pull on the grid?
Nuclear, for example, can replace coal if we want it to.
As there's no (or little) political will to do this, the private sector (and specifically those that recognize the problem) can act directly.
And since it's the 21st century, it seems like Kickstarter is the way the private sector can do it.
