A special report by BBC describes the territorial fight in the South China Sea between the neighboring countries of China, Vietnam and Philippines. The latest move from China's part is the creation of artificial islands upon submerged reefs in an attempt to claim more islands. Offshore construction works are in progress and captured by a video, while in the meantime Philippines are colonizing reefs with civilians trying to face the Chinese challenge.
The construction of the first offshore wind farm has just started on US ground in Block Island , a small island 13 miles south of Rhode Island, last Monday. Upon completion, the wind farm will supply all homes and businesses on Block Island with 30-megawatts of electricity. This is the first long awaited step in the offshore wind farm industry on U.S. ground and hopes are expressed that many more projects will follow.
The method that is currently being used to store wind energy is pumped storage: the surplus of wind power is used to pump water from a hydrant tank (lower tank) to a water reservoir tank (top tank) and it is stored as water at a high level.
