The BIGGEST problem with clean energy

So, is the energy used to pump the water back up more than the energy made?
You have to get the same amount of water back up as comes down.

There just isn't any need for these massive power generators.
 Smart people out there should be able to have individual house power plants rather than these obnoxious mega constructions.

For example
800 watts of solar
a brushless motor that can turn at 1600 rpm on 200 watts, (we all know how efficient and powerful they are)
a generator that can output 1.6kw at1600 rpm
= 1.4kw into a storage battery for night usage
that's more out than in.

Laws of physics? 1687. 
Time to re write them . 
All this stuff is relying on old technology, wind , solar, water.

Remember once we couldn't fly to the moon?
