The energy world is not keeping up with Elon Musk, so he's trying to take matters into his own hands. Musk, chairman of the solar installer SolarCity, announced [on June 17] that the company would acquire a solar panel maker and build factories an order of magnitude" bigger than the plants that currently churn out panels. Musk is also a founder and the CEO of the electric vehicle maker Tesla Motors, which is planning what it calls a "gigafactory" to supply batteries for its cars. In both cases, Musk's goal is to make sure that the components critical to his vision of the future - electric cars and solar energy - are available and cheap enough to beat fossil fuels. Musk's future customer could ignore traditional energy companies completely. They'd have SolarCity panels on their roof that would generate enough power [to] charge up a Tesla [car] in the garage. A Tesla battery could then power the home at night with stored solar power. Musk has made a career of thinking far into the future. He is also the CEO of SpaceX, the rocket company with an ultimate goal of enabling people to live on other planets. SolarCity says it won't try to turn out more of the garden-variety panels now clogging the market. Instead, it wants to make panels that are more efficient, and make them at a low cost in huge factories in order to reduce the overall cost of solar electricity. Just as he drew customers to electric vehicles by making sleek, fast sports cars, Musk wants to attract homeowners to solar with pretty panels. "We want to have a cool-looking aesthetically pleasing solar system on your roof," he said.
