Wind energy - is this the future?

On 10 July, 2015 it was announced that Denmark reached a 100% efficiency of electricity generation based on wind energy. This is a historical record worldwide; actually the generation of energy via the wind generators reached as high as 140% of the daily needs of Denmark. Excess energy was exported to Germany, Norway and Sweden. In average, wind energy generation accounts for less than fossil fuels energy generation. However, until 2020 Denmark will be able to generate more than 50% of its yearly needs from renewable sources. This amazing goals seems more than achievable since Denmark is one of the countries hevily investing in renewable energy sources. This trend is expected to continue and press the oil prices even lower in the years to come.
