  Norway's Wind Catching Systems (WCS) has made a spectacular debut with a colossal floating wind turbine array it says can generate five times the annual energy of the world's biggest single turbines – while reducing costs enough to be immediately competitive with grid prices.                                                                                                                                                                              Standing more than 1,000 ft (324 m) high, these mammoth Windcatcher grids would deploy multiple smaller turbi...

 With emerging trend of solar power the most fundamental concern is the climate dependency  of the power generation. That is , power is generated when the sun is available and not necessarily when the demand is high.  The electric power grid operates based on a delicate balance between supply (generation) and demand (consumer use). One way to help balance fluctuations in electricity supply and demand is to store electricity during periods of relatively high production and low demand, then release it back to the electric power grid during periods of lower production or higher demand. In some cases, storage may provide economic, reliability, and environmental benefits. Depending on the extent to which it is deployed, electricity storage could help the utility grid operate more efficiently, reduce the likelihood of brownouts during peak demand, and allow for more renewable resources to be built and used. Energy can be stored in a variety of ways, including: Pumped hydroelect...
