Solar energy is fine when the sun shines. Wind energy is fine when the wind blows. But when there is no sunshine and no wind?
The answer is a much more efficient energy storage. One of the big challenges is to store surplus electricity from solar and wind sources.
The most common approaches are to pump water uphill for hydroelectricity storage, produce hydrogen, store heat, compress air and making different forms of batteries. The Tesla house batteries seem to be increasingly efficient – and economic.
Small entities producing, and storing hydrogen from solar and wind electricity are promising. Hydrogen is easy to transport, it can be used much like petrol – but with no pollution.
