Tesla’s Powerwall will allow us to disconnect from the grid completely, writes Vivek Wadhwa.
Most people are skeptical that we’re heading into a clean-energy future. They find it hard to believe that solar energy is fewer than 14 years away from meeting 100 per cent of today’s energy needs. They argue that today solar energy hardly provides one percent of earth’s energy needs and that we can’t effectively store sunlight — and therefore have a long way to go.
But when technologies advance exponentially as solar is doing, one percent solar means we are halfway from 0.01 percent to the goal of 100 percent. The prices of solar panels have fallen 75 per cent in the past five years and are advancing on a scale comparable to Moore’s Law, as tech guru Ramez Naam has documented. At this rate, solar energy is only six doublings away from 100 per cent…
