What to do with electricity produced by wind and sun, which is not used immediately during times of reduced power consumption? In order to integrate renewable energies fluctuating in a sustainable energy system, it is necessary to find ways of storing excess energy produced. It is already possible to store electricity in the form of water (hydro Pumped Storage-turbine [1]), again transformed into electricity through turbines during peak periods. However, these storage capacities are very limited.

Integrating renewable energy in an electrical network originally designed to transport electricity from a central production is both a technical challenge and an economic challenge. Not only because renewables deliver lower power, but also because they are less controllable and less predictable. When conditions of exposure to sun and wind are the best, sites to generate a maximum output current, but it is also necessary that this maximum corresponds to periods of high demand, which is rarely the case. Besides the phenomena of intermittent production.

Today the new models of huge turbines and conventional measurements of wind speed with meteorological masts are not feasible because of cost and their technical approaches. Therefore, researchers from the Chair of Wind Energy (SWE) at the University of Stuttgart are working with researchers from the University of Oldenburg in an alternative remote sensing technique.
Wind energy is now considered the most important source of renewable energy. The optimal performance of the latest generation of large wind turbines is possible through the reliable measurement of the input characteristics of the
wind. Experience has shown that accurate estimation of power generation based on wind speed is a challenge.
LIDAR technology (Light Detection and Measurement) is being developed and tested for application in wind energy. This technique of laser-based measurement makes measurements of wind fields in a more flexible and economical. Currently, LIDAR is the best candidate to replace wind measurements based on meteorological masts used in calculating the power curves for wind farms offshore.

He says that Washington “est Espaa looking” for his leadership role in renewable energies
Humanity as we know it today Proximo collapse in 30 or 40 years and “all” species acabarna end of this century if global climtico remains at the current rate, according warned against Today the president of the ‘Foundation on Economic Trends’, Jeremy Rifkin.

Researchers at the Fraunhofer Institute for Chemical Technology (ICT) have developed an innovative battery circulating redox ( “redox-flow“). This type of battery has the following advantage: when it is discharged, the electrolyte fluid from which it operates can be simply exchanged against an electrolyte nine, which requires as much time as filling a gas tank.
To meet the challenge to move one million units by 2020 in Germany, one of the problems that remain to be addressed is that of energy storage.
