Energy

2. If an energy resource is not available at times when it is needed then it is difficult to rely on it, for example, wind, solar, tidal energy.
5. is a solid ice-like crystalline solid found in locations at low temperatures, such as polar regions, or under high pressure, for example, in oceanic sediments around continents.
8. energy resources are either not being formed, or re-form so slowly that current use reduces the amount available for future.
11. Coal that is too deep to be mined can be burnt underground under controlled conditions to produce a mixture of fuel gases including hydrogen, carbon monoxide and methane.
13. sources naturally re-form relatively quickly so using them does not necessarily reduce future availability,
14. is a measure of the amount of energy in a given mass of energy resource, for example, oil, coal, uranium, or wood.
15. Renewable energy source.Locational factors include reliable precipitation, impermeable geology, large catchment.
16. Lithosphere Term -includes all of the material that exists in the lithosphere. It includes the mineral that can be exploited now, that which will be exploitable when prices rise, or new technologies are developed and that which will never be exploitable.

1. The amount of energy that was used to make and install an item.
3. A method to reduce carbon dioxide emissions, by removing the gases and storing them in underground geological structures.
4. injecting steam or bacteria to reduce the viscosity of oil.
6. Thermal energy extracted from the earth's crust.
7. can be used to carry out seabed surveys and to inspect underwater production equipment and pipelines.
9. injecting water or gas to displace oil and drive it the surface for collection.
10. It involves drilling into the earth and directing a high-pressure mixture of water, sand and chemicals at a rock layer, to release the gas inside porous rock.
12. are a mixture of sand, clay, water, and bitumen(viscous oil).
