When it comes to personally investing in green energy, installing solar panels on your roof is one of the more practical options available to us regular people. Wind turbines and hydro power stations are awesome, but they’re not something the average suburban or metropolitan consumer really has much to do with up close. Solar technology, on the other hand, is much more personally accessible.
But how much of a contribution can solar really make to the electricity grid? According to a new analysis by the US Department of Energy, it’s a pretty big chunk. If all of the available roof space that could be practically fitted with solar panels were maxed out, it could make up the equivalent of 39 percent of the nation’s electricity.
