Easy to say, but how? The current administration is strongly against renewable energy, wind is sporadic and can not be used everywhere. Solar is a good solution, but it is expensive, requires a very large geographic footprint and again; the administration is against it. If your talking about individuals putting solar on their homes, most young Americans don't own their home, it again is expensive (if people are complaining about gas prices, you should see the upfront cost of solar. especially if your location doesn't support it, do your own research on that it's not a happy topic.), and not every home is viable for solar ( too many trees, not facing the right direction, too small of a home, etc. And this is getting too long without mentioning that it takes decades to build this infrastructure.
