  As countries around the world seeks to reduce their reliance on fossil fuels, renewable energy sources like wind are being promoted as alternative power sources.

According to a researcher from Stanford University, there is enough power in the wind to power the world many times over. In a study published in the Proceedings of the National Academy of Sciences, it is possible to harness hundreds of terawatts of electricity using wind turbines. This is far in excess of the world's energy need. Of course, it would take a massive investment in infrastructure to realise this and some analysts say it is just not realistic. To achieve the maximum output potential, 1.5 billion massive windmills need to be installed on land and offshore.

Even with the recent heavy investments in wind power, the total wind power capacity worldwide is around 250 gigawatts. This is less than a hundredth of the world's energy need. The researcher, Mark Jacobson estimated that four million five-megawatt turbines could produce half of the world's 2030's energy needs. That is one goal that is worth exploring.
