Try to minimise electricity use: its generation needs a lot of energy, mostly heat produced
in coal, gas or nuclear plants. Using electric hot water heaters or space heating is extremely
inefficient. At the power plant, some 60 percent of the energy is lost as waste heat.
Another 10 percent is lost in electricity lines and transformers before the electricity even reaches your home.
