I'm doing an assignment at the moment and answers from EXPERTS! If you aren't an expert or doctor currently studying the matter( and imean really studying), please state at the end of ur answers. f you would be so generous, please leave your references below as well. That goes for experts too!

Answer 1

The people who are really studying the matter are probably all too busy to spoon feed you answers you should be finding out on your own.

But I'll give you a hint, it only matters if your electricity source is c**p (say fossil fuels or renewables that need fossil fuel backup).
