    One of the interesting energy capture ideas I’ve seen with Solar and wind is based on kinetic potential energy in high-rise buildings. So you build a sort of heavy weight elevator that is elevated during windy and sunny hours and then it slowly gets released and gravity driven friction generating energy.

    This coupled with solar windows and it’s a pretty neat idea (not sure how viable though)

      This might work on the scale of a building to even out its own power usage throughout a day, but to make a difference on a city grid scale, you need an insane amount of height and/or weight.

      Check out Pumped Water Energy Storage. It’s the same concept but uses water as the weight. Doing the math on the Ludington Pumped Storage Power Plant’s active capacity, it stores over 100 billion pounds of water.
