9. Solar Energy Using the sun for energy purposes is known from ancient times. It is the largest fully renewable resource production electric power not only on Earth, but all planets and satellites in the solar system. Alien space ships and stations sent from Earth, using a primary energy source solar energy. 9

33. Geothermal Geothermal energy is heat from the Earth. It is clean and permanent. Geothermal resources stretch of shallow water and up the hot rocks, located a few miles below the earth's surface. Some geothermal power plants use steam from the tank to supply turbine / generator, while others use the hot water for heating the liquid, which operate it evaporates and drives the turbine. 33

36. Hydro power Running water creates energy that can be caught and turned into electricity. This is called hydropower the most common uses hydropower station dam built on the river to store water in the tank. Water released from the reservoir flows through the turbine which is rotated, which in turn activates a generator that produces electricity. But hydropower does not always need reservoir. Some large hydropower stations using just a small canal to channel water from rivers in the turbines. 36

45. Hydrogen Hydrogen is the simplest chemical element, atomic it consists only of one proton and one electron. Also in the universe it is the element abundance. Despite its simplicity and widespread, hydrogen does not occur naturally as a gas on Earth - it is always associated with other elements. In water and many organic compounds, particularly hydrocarbons, which are a major component of our fuel. Such as gasoline, natural gas, methanol, propane. Hydrogen is rich in energy and in addition, an engine that burns pure hydrogen hardly pollutes the environment. NASA from 70th years using liquid hydrogen for the removal of the shuttles and other rockets into orbit. The cameras of hydrogen fuel powered electrical systems of the shuttle, which is given pure organic product - clean water to drink from the crew. 45
