Power generated by a wind turbine largely depends on the wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes (such as turbulence) to the wind profile, a turbine will produce different amounts of power. This variable power can be predicted by looking at atmospheric stability, according to new research.

But recent work may help this balance through a project that alerts control room operators of wind conditions and energy forecasts so they can make well-informed scheduling decisions. This is especially important during extreme events, such as ramps, when there is a sharp increase or decrease in the wind speed over a short period of time, which leads to a large rise or fall in the amount of power generated.

But there's a catch, according to a new study: rising temperatures decrease wind speeds, making for less power bang for the wind turbine buck.

On the way to the consumer lots of energy is lost. New electronic components will change things in future.

The first offshore plants are already being erected, and many more are planned. But the farther they are away from the coast, the more urgent becomes the problem of transferring the current with as low a loss as possible. Over long distances, this is possible only with direct current.

A lot of rare metals are needed to make photovoltaic panels, rare earth magnets for wind generators, fuel cells and high-capacity batteries for hybrid and electric vehicles. But most industrialized nations, including the United States, are almost entirely dependent on foreign sources for those metals. The only way this is going to change is if there is more domestic exploration and mining, a leading expert says.

On the Continent, the concept of Norway as Europe’s green battery has caught on – but is it feasible in practice?
