Like solar radiation, the ocean is another widely available and distributed energy source. The energy in the ocean is in part kinetic energy in the form of tides, currents, and waves, and part thermal energy from the sun stored as heat. The quantity of energy stored in the ocean is enormous but can be quite diffuse; in some cases, it is about the same as from solar radiation and, as a result, it is difficult to harness. Marine energy systems can be classified into four main groups: (more…)

In 2006, total world wind generating electricity capacity was around 72,000 MW, producing some 160 terawatt-hours (TWh) per year of electricity. As of the end of 2006, the top wind producers were Germany, with 20,622 MW; Spain, with 11,615 MW; and the United States, with 11,575 MW.

Even so, wind accounts for only about 1 percent of the world’s total energy use. (more…)

Wind energy comes from the mismatched heating of the planet that runs all day and night, heated and cooled by the sun. They are also come as effect of the different between land and sea temperature, and natural barriers such as mountains. (more…)

The wind power potentially could produce 40 times more electricity than worldwide energy consumption annually, according to research led by Professor of Planetary Sciences Department of Earth and Harvard University Michael B. McElroy. Only the U.S. has enough wind resources to cover wind technology with 16 times its electricity demand. (more…)

The main reason why there is an on and off attempt of oil prices is due to depletion of our conventional energy. Our fossil fuel reserved almost nearly to its end. Hence, the world market tends to balance the trend of supply and demand. If that happens to be impossible, many countries will suffer because of insufficient of energy. We are going to take a look the advantages and disadvantages of wind energy and find out how to resolve this energy shortage. (more…)
