Some sources of energy – like ethanol that powers the engine of a car – are made from corn. Other biofuels are made from vegetable oil. Other renewables include solar energy, wind energy and energy from rain, trees, the tides at sea; and from the earth itself — as geothermal energy.
Nonrenewable energy comes from sources such as the uranium, completely consumed in the production of nuclear energy; as well as the fossil fuels — coal, petroleum and natural gas — that can not be replaced.
Since energy costs will make up a good portion of household expenditures it will pay to make a few changes and then review the impact that efficient energy use can have on the monthly household budget, so it’s both lean and “green.”
