2. What changes can be made to improve energy management within a home, school or community?

Vocabulary **thermal energy - the energy of heat -** The total potential and kinetic energy associated with the random motions of the molecules of a material.

**radiant energy - the energy of waves; light, sound -** Any form of energy radiating from a source in waves.

**electrical energy - the energy of electricity -** The energy associated with electric charges and their movements.

**chemical energy - the energy stored in chemical bonds -** Energy stored in a substance and released during a chemical reaction such as burning wood, coal, or oil.

**mechanical energy - the energy of moving parts -** The energy of motion used to perform work.

**nuclear energy - the energy stored in the nucleus of an atom -** Energy that comes from splitting atoms of radioactive materials, such as uranium.

**fossil fuels -** Fuels (coal, oil, natural gas, etc.) that result from the compression of ancient plant and animal life formed over millions of years

**solar energy -** The radiant energy of the sun, which can be converted into other forms of energy, such as heat or electricity

**wind energy -** A renewable source of energy used to turn turbines to generate electricity

**hydroelectric -** uses moving water to power a turbine generator to produce electricity

**geothermal -** The heat energy that is produced by natural processes inside the earth. It can be taken from hot springs, reservoirs of hot water deep below the ground, or by breaking open the rock itself.

**biomass -** Any organic (plant or animal) material which is available on a renewable basis, including agricultural crops and agricultural wastes and residues, wood and wood wastes and residues, animal wastes, municipal wastes, and aquatic plants.

<span style="color: #000080; font-family: Arial,Helvetica,sans-serif; font-size: 17px;">**Greenhouse Effect -** The effect of the Earth's atmosphere, due to certain gases, in trapping heat from the sun; the atmosphere acts like a greenhouse.

<span style="color: #000080; font-family: Arial,Helvetica,sans-serif; font-size: 17px;">**generators -** A device that turns mechanical energy into electrical energy. The mechanical energy is sometimes provided by an engine or turbine.

<span style="color: #000080; font-family: Arial,Helvetica,sans-serif; font-size: 17px;">**turbines -** A device with blades, which is turned by a force, e.g. that of wind, water, or high pressure steam. The mechanical energy of the spinning turbine is converted into electricity by a generator.

<span style="color: #000080; font-family: Arial,Helvetica,sans-serif; font-size: 17px;">**photovoltaic cells / solar cells -** A device, usually made from silicon, which converts some of the energy from light (radiant energy) into electrical energy.
