One year’s worth of solar energy hitting the earth’s surface exceeds the potential of all the known energy reserves for oil, coal, natural gas and uranium. In just one hour, the solar energy reaching the earth’s surface is around 173,000 TWh (terawatt hours, or one trillion watts). This compares to humanity’s annual consumption of 160,000 TWh (in 2017).
So capturing the sun’s energy to power our lives seems the most obvious and cleanest way forward. Right? Unfortunately, it’s not quite that simple.
