Gates points out that this money-as-sole-incentive approach is kinda BS when the future of the planet is at risk. Instead, the people like him who can afford to take risks should be the ones doing so — even if the ROI doesn't come through quite as quick or strong as some hip tech startup.

Gates has committed $2 billion of his own to incentivize clean energy R&D, and he thinks others should do the same.

Of course, there's more than one kind of clean energy and no guarantee of which works best. So Gates says fund 'em all!
