PS Ch.23-2 "Energy & Resources"

5. A non-renewable, clean source of energy that is produced by controlling fusion reactions between atoms.
7. A resource that forms at a rate that is much slower than the rate at which the resource is consumed.
8. A solid type of fossil fuel that is mined and used as a source of producing electricity.
9. The energy produced by heat within the earth that is used to produce electricity; only good in areas where molten rock is somewhat close to the earth's surface.
11. A type of fuel produced by contemporary biological processes such as agricultural and anaerobic digestion; includes ethanol produced from corn and sugarcane as well as particular types of diesel.
13. A reaction that combines oxygen with another substance to produce carbon dioxide, water, and energy that is given off; the burning of any substance; often fossil fuels.
15. A renewable, clean source of energy that is available as a result of temperature differences in the air.

1. A device with fanlike blades that turn when pushed, for example, by water or steam. This is often attached to a generator.
2. A natural resource that can be replaced at the same rate at which the resource can be consumed.
3. A renewable, clean source of energy from moving water that flows through a turbine causing it to spin and generate electricity.
4. A device that converts kinetic energy into electrical by spinning an electric coil between the poles of a magnet. The magnetic field induces an electrical current in the wire by effectively pushing the electrons along.
6. A renewable, clean source of energy from the sun that is converted into thermal or electrical energy.
10. Cleanest burning fossil fuel; also known as CH₄ or natural gas.
12. Coal, oil, natural gas, and other fuels that are ancient remains of plants and animals; a non-renewable resource.
14. A fossil fuel that is a mixture of many substances that comes out of the ground as a tar-like liquid; gasoline, diesel fuel, kerosene, etc. are extracted from it.
