That's the 'solar future' option. As far back as the eighties, it was generally agreed that the future would be either solar or nuclear. Yes, I know solar power IS nuclear but it's already up and running, it's located at a safe distance and it's completely maintenance free. Geothermal power somehow got left out but we can include it in the solar option because the problems of harvesting it are similar.
The solar future requires that we spread our energy collecting devices far and wide. Those 'devices' take many forms, some of them organic, but they all have one thing in common; they don't yield vast amounts of cheap energy, at least not compared to oil. Expensive energy will inevitably lead to us being a lot more frugal with it.
The nuclear future is still up for grabs. There are two ways to do it: the clean way and the dirty way. The clean way isn't so clean but the dirty way is very, very dirty. Moreover, the dirty way isn't so easy but the clean way is very, very hard. Whatever the difficulties, it's the only option that offers us energy off the scale of anything we have today and we'll certainly need it somewhere down the line. Some time in the next 5,000,000,000 years would be nice.
