Renewable energy sources?

This term "renewable" seems too much like conventional wisdom.  No energy source is renewable.  They will all die out eventually.  The sun will burn itself out.  Every star does that.  Entropy is increasing in the universe.  Things fall apart, that is the natural order.  It can be only relatively renewable in the sense that the new are born to take the place of the old.

Can humans improve upon nature? Not according to this:



But not so fast. People may be able to make things that are better than the natural thing. This isn't necessarily true all the time, but sometimes it is. A car is better than a horse.  But wait, maybe that depends upon how you define "better".

But cars can be made better than they are at a faster rate than evolution can supply the changes.
