I am not sure I follow; how would your switch force people to buy energy from the grid?
It can't, but you could certainly stop the current from flowing into the grid by disconnecting the providers from the grid at peak times. And, let's be honest, when has an excess of power gone unused for long. Lots of sun means lots of need for refrigeration, for example. We'll always find something to do with the power.
Maybe... but does it make sense for us to worry? At present speed, 100 years of technology is an abyss, 500 are just unthinkable. Try to imagine Cortès, Columbus, Da Vinci and Ivan the Terrible debating how to use their technology to save us people of the XXI century from some disaster they predicted. Aren't they cute?
Maybe, but our perception of how technology is moving forward is kind of skewed by our short lifespans. Very little of the technology behind what we view as 'modern' technology was unheard of 100 years ago. Or 200 years ago. And truly novel avenues of science aren't popping up like they were in and around the industrial revolution. In my lifetime, all we've done is refine things. Every time I start looking into some interesting technology, I find references to some fluffy-shirted Victorian who came up with the idea. I feel like we've been feasting on a thanksgiving drumstick, but now all that is left is that gristly part at the ends.
I'm not saying we shouldn't take good care of the environment; just that we should never forget that our children and grandchildren will know a lot more than we do.
Will they? I suspect they'll adapt, but I don't see any game changing technology on the horizon, yet. And, the idea that somehow, in the future, all our problems will be solved is eerily similar to religion's promise of heaven in the afterlife. It gives people cover to do dumb stuff now because it'll all work out in the end.
