Gravity Could Solve Clean Energy’s One Major Drawback
Finding green energy when the winds are calm and the skies are cloudy has been a challenge. Storing it in giant concrete blocks could be the answer.
All very noble, but the need to construct, transport and erect must take one hell of a lot of energy in the first place, how long does that take to recoup ?
Humans will have to learn to do with less, or perhaps the solution will boil down to fewer humans.
