> Now is the time to invest big in renewable energy research and encourage our children to participate in it, otherwise we are screwed.

We need to look at getting our environmental footprint under control. Renewable energy may help with that in the short term, but switching to renewables at scale will also have a significant environmental footprint. Remember, climate change is the environmental issue of our generation. Prior generations had their environmental issues (ozone hole, acid rain, deforestation). Future generations will have their environmental issues, for as long as we don't take responsibility and curb our resource use.
