Yes, I have always thought the electric cars were a bit daft.........after all the power still has to be generated, but hope is on the horizon...I'm sure I read that someone has made an engine that runs on water....causes no pollution and is 'green'.

Economy seven does not store electricity. Coal fired power stations can't be switched off quickly so there is often an excess of power at night so they encourage people to use more at night and less during the day by selling it to you cheaper. You pre heat storage heaters and hot water cylinders at night and use that heat and hot water during the day.
Storage heaters have always been rubbish in my opinion, I have lived in a few houses with them.
