New analysis by the US Department of Energy shows that if all the available roof space that could be practically fitted with solar panels were fully utilised, it could provide almost 40% of the US' electricity, significantly reducing the nation's reliance on fossil fuel-based power. The study, published in Nature Energy, is based on a survey of more than 1,000 rooftops across the US, and found that, even though there are currently only about half as many rooftop solar systems installed per
New analysis by the US Department of Energy shows that if all the available roof space that could be practically fitted with solar panels were fully utilised, it could provide almost 40% of the US' electricity, significantly reducing the nation's reliance on fossil fuel-based power. The report adds that this "only estimates the potential from existing, suitable rooftops, and does not consider the immense potential of ground-mounted PV" which would drastically exceed this percentage.
