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 Tuesday 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.
"If we don't do this we felt there was a risk of not being able to have the solar panels we need to expand the business in the long term," Musk said Tuesday in a conference call.
