What is Energy?

In physics, energy is a quantity that can be assigned to every particle, object, and system of objects as a consequence of the state of that particle, object or system of objects. Different forms of energy include kinetic, potential, thermal, gravitational, sound, elastic, light, and electromagnetic energy.Any form of energy can be transformed into another form. When energy is in a form other than heat, it may be transformed with good or even perfect efficiency, to any other type of energy.

Renewable energy sources include:
 * Solar energy from the sun, which can be turned into electricity and heat
 * Wind
 * Geothermal energy from heat inside the Earth
 * Biomass from plants, which includes firewood from trees, ethanol from corn, and biodiesel from vegetable oil
 * Hydropower from hydroturbines at a dam

Nonrenewable Energy We get most of our energy from nonrenewable energy sources, which include the fossil fuels — oil, natural gas, and coal. They're called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth's core and pressure from rock and soil on the remains (or "fossils") of dead plants and creatures like microscopic diatoms. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

We use renewable and nonrenewable energy sources to generate the electricity we need for our homes, businesses, schools, and factories. Electricity "energizes" our computers, lights, refrigerators, washing machines, and air conditioners, to name only a few uses. Most of the gasoline used in our cars and motorcycles and the diesel fuel used in our trucks are made from petroleum oil, a nonrenewable resource. Natural gas, used to heat homes, dry clothes, and cook food, is nonrenewable. The propane that fuels our outdoor grills made from oil and natural gas, both nonrenewable.

Potential energy is stored energy and the energy of position — gravitational energy. There are several forms of potential energy. ||~ ===Kinetic Energy=== Kinetic energy is motion — of waves, molecules, objects, substances, and objects. ||
