Rock Cycle:
Mining:
Ore: a rock that contains a large enough concentration of a mineral making it profitable to mine.

North America is the New Oil Region of the world!! The Oil Sands or Oil Shale
ACID MINE DRAINAGE:
* When mines are finished, they just sit there and water runoff brings leeched out chemicals and metals into the groundwater and river systems.
All About Coal:
Coal Formation: Peat is the least efficient, Anthracite the best
OIL:
Petroleum (Crude Oil) Formation: microscopic aquatic organisms in sediments converted by heat & pressure into a mixture of hydrocarbons.
Petroleum Pros: cheap, easily transported, high-quality energy.
Cons: reserves depleted soon, pollution during drilling, transport and refining, land subsidence, burning oil produces CO2.
Oil % by country:
1 Saudi Arabia 19.78%
2 Canada 13.21%
3 Iran 11.10%
4 Iraq 10.60%
5 Kuwait 8.71%
6 Venezuela 7.37%
7 United Arab Emirates 7.25%
8 Russia 4.45%
9 Libya 3.24%
10 Nigeria 2.69%
How a Coal Power Plant Works
Nuclear Energy:
Uranium-235 isotope is "cracked open" and its energy is used to heat water to turn a turbine.
Nuclear Fission: nuclei of isotopes split apart when struck by neutrons.
Nuclear Fusion: 2 isotopes of light elements (H) forced together at high temperatures till they fuse to form a heavier nucleus. Happens
in the Sun, very difficult to accomplish on Earth, prohibitively expensive.
Natural radioactive decay: unstable radioisotopes decay releasing gamma rays, alpha & beta particles (ex. Radon).
Half-life: the time it takes for 1⁄2 of the mass of a radioisotope to decay. A radioactive isotope must be stored for approximately 10 half-lives until it decays to a safe level.

How a wind turbine works.
Top Ten Countries for Wind:
10) Portugal
9) Denmark
8) Italy
7) China
Having garnered the seventh spot in the most efficient user countries of wind energy in the world is Asia’s pride – China. Though considered by many to be very environmentally unfriendly, China is quickly disapproving it by doing well on harnessing wind energy. Wind turbines installed in many places of China work very efficiently to provide the energy needed by the billions of residents; the fact that their use is being increased at a very rapid pace. The high population of China is one drive to find alternative power sources which are renewable and inexpensive, with a new trend in technology that can meet these needs in a very efficient and environment-friendly manner.
6) Spain
5) The United Kingdom
4) France
3) India
This country is big, not only in terms of land area but also in the total number of population. India may be considered a developing or third world country, but when it comes to wind energy, India is one of the top ten; in fact, it is the third on the list of the most efficient user countries of wind energy. 5% or less of the power needed for the country is supplied by the wind, but this percentage increases steadily each year. India is looking forward to surpass larger and more developed countries where alternative energy sources are involved.
2) Germany
It is called to be one of the powerful countries in the world like the United States. Germany is, as it ranked the second among the top countries when it comes to going green concerning energy. In fact, around 10% or more of the energy used by the population of this country is supplied by wind turbines. Germany consistently retains one of its chief routines, which is harnessing wind power very efficiently because they believe that utilizing wind energy instead of fossil fuels helps reduce the carbon footprint that the residents of Germany are contributing on Earth.
1) The United States
The United States is the number one country leading the use of power from wind turbines. Wind energy through wind turbines are used very efficiently in the United States. In fact, these machines are placed in greater numbers to further benefit more areas and more people and to break away from the dependence on foreign oil and fossil fuels which bring potential hazards to air and the environment. People in the country greatly believe that wind energy is a clean and renewable source of power, the reason why United States is utilizing wind turbines in greater amounts than ever before.
