Wind energy supplies 3 percent of global electricity needs and will soon supply more electricity than nuclear power. In 2011, some 50 billion euros were invested in wind, leading some to say it’s cheap and creates jobs.
Wind energy is booming and it is gaining in significance worldwide. It supplies some 20 percent of electricity in Spain and Denmark as well as about 10 percent in Germany. By 2020, the share of wind energy will have risen to between 20 percent and 25 percent in Germany, according to estimates.
Last year, new wind power plants with a total capacity of some 40 gigawatts (GW) were installed worldwide, according to the World Wind Energy Association (WWEA). This puts wind energy’s global capacity at 237 GW by the end of 2011- the equivalent of what some 280 nuclear power plants generate. Currently, there are some 380 nuclear power plants producing electricity worldwide.
