Not quite. When I visited a hydro plant near Canberra as part of first year electrical engineering, one of the things they do do is to buy power when it is cheap, pump water up the dams, and then use it to generate power during peak times then sell it back on the energy market. So unused power can be stored.

Regarding earth hour - take a look at Cleanup Australia day. Same kind of thing. You can even argue it is also a conspiracy whereby councils save on cleanup fees by duping their constituents into doing it for free
