"Solar panels are getting cheaper. The learning rate for solar energy is (probably) the steepest of any energy technology yet deployed. So we can be pretty much assured that within the next decade we'll have enough solar power to power anything we want" Again, predicting the future is notoriously hard. Current rate of progress cannot be extrapolated to infinity. Most exponentials are S-curves in disguise. Take a look at Moore's Law.
