Thoughts about regulation

One thing I have noticed in recent years is that renewable energy is very hard to control, sometimes we get too much of it, other times there is a shortage; if it is night time and there is no wind there may not be enough of it. I often try to imagine ways to regulate the supply of this natural energy so it is steady and persistent. 

 

I imagined tower blocks that were filled with cartridges that stored kinetic energy in lifted weights that pulled a system of gears that turns a dynamo. The cartridges contain a small electric motor that resets the cartridges when there is too much natural power being produced. 

Another way would be to compress air into tanks when there is excess power and then release the compressed air though a generator when the power level is low. 

Perhaps cheap high capacity batteries would be invented in the near future.
