California is the largest state in the union, has the 5th largest economy in the world, and provides the majority of the food for the rest of the US. California is also leading the way for clean energy initiatives. Programs set in place by the current governor, and governors before him, have California on track to source 50 percent of their energy from renewables in the next 15 years. Conservation programs, and incentives that minimize fossil fuel use are pointed to as being major factors driving the changing energy grid.
