The BIGGEST problem with clean energy

These ideas are great and worthy of consideration, but how about in the short term developing a way to completely capture the emissions from fossil fuel so they don't pollute and continue to exhaust that resource first?? Before that's depleted, put the combined scientific effort into creating a fusion source of power. These stop-gap methods are just not that "friendly" if they need to be developed from scratch and use a lot of precious recourses.
