For the liberal hoax about climate, see global warming.
Energy is the ability to do work.[1] In physics, energy is a conserved quantity, and a closed system of interacting particles is known to always have the same value for its energy; this is known as the law of conservation of energy.[2] The SI unit of energy is joule. Energy can be converted into various forms like Potential energy, Kinetic energy, Chemical energy and Thermal energy, but it cannot be created or destroyed.
More generally, energy is a source of usable heat or power.
According to the Theory of Relativity the formula of energy is E=mc2.
Energy efficiency
There is unanimous agreement from all points of the spectrum that the cheapest, easiest and quickest way to save on energy costs and reduce imported oil is to reduce waste and be more efficient on the consumer side--especially in insulating residences and using more efficient appliances and automobiles. Many local electricity and gas companies have rebate programs; the federal government offers $1500 tax rebates to ordinary Americans, and many states have somilar programs in 2010.[3]
