The greenest way to stay warm is to use green energy. Green energy is electricity which is generated from a renewable energy source such as hydro, solar, tidal or biomass energy. The opposite is electricity generated from the conventional methods of burning fossil fuels in a power plant. These fossil fuels are oil, gas and coal, which are definitely finite in quantity and not renewable. Nuclear energy is slightly different in that only small quantities of uranium and plutonium are needed to produce electricity. Still, uranium and plutonium deposits are not limitless and besides, everyone knows about the inherent dangers in producing electricity from radioactive material.
Now for the majority of people using green electricity is not an option. For the poorest in Africa and Asia burning wood and animal dung is the only available source of energy. These are valuable resources and burning them contributes to global warming. So what can we do until we can buy green electricity or make our own green electricity at a reasonable price? Well the answer is pragmatic and simple. Just use less electricity.
In winter this is a lot to ask. You cannot turn off the heating and sit around wearing five sweaters. You still feel cold and you get really demoralized. Recently, a lot has been written about using space heaters to save electricity.
