The Prodigious Sun

Is the Sun an efficient producer of energy via nuclear fusion?

While humanity may be years away from commercializing nuclear fusion power, the Sun has been doing it for a while now (and for free!). The Sun is the most efficient generator of nuclear power in our solar system. Inside the Sun, nuclear reactions are happening at a seemingly impossible rate. Hide your kids and hide your wife though, because eventually the Sun is going to run out of Hydrogen and will no longer be able to produce these reactions. When this happens, about 5 billion years from now, will humanity have come up with a way to circumvent the destruction of our society that would come as a result? It took us less than 2000 years to get to sliced bread, so I’m confident we’ll come up with something.
