Wind power is the world's leading renewable energy source. Investment and maintenance costs are low and despite the minimal infrastructure required, yields are high. Around the world, wind energy is booming.
One of Africa's largest wind farms is located in Egypt. It's powering a rapidly changing country.
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.
With its plentiful sunshine and frequent winds, Morocco boasts ideal conditions for a flourishing renewable energy industry – as illustrated by the success of a wind park in Tanger that is still growing.
Wind parks powering the Turkish economy are also helping offset carbon emissions from air travel.
The booming Southeast Asian state is setting up the legal and technical base to harness wind power.
Powerful volcanoes make El Salvador a prime spot for harnessing geothermal energy.
Our world runs on fossil fuels releasing lots of carbon emissions into the atmosphere. Global warming is a direct result of this. But the use of clean sources of energy - like the sun, wind and water - is gathering pace.
