Every three weeks, we bring online as much solar power as we did in all of 2008...That’s why, over the past six years, we’ve done more than ever before to combat climate change, from the way we produce energy, to the way we use it.

Cutting our education budget, that's not a smart choice. That will not help America compete with China.
