Mankind invented numerous ways of producing electricity and in the past couple of decades we have finally become more aware of the benefits of sustainable energy and renewable energy resources. Instead of using coal or getting power from nuclear power plants (which are supposed to be 'clean', however people are frightened of their potenitially deadly force, mainly due to past experiences regarding Chernobyl and Fukushima), we have now started to use natural resources, gathering power from the sun, the wind and the waves.

In India the Cochin International Airport (CIAL) is proving everyone, who claim it is next to impossible for a big company to function on alternative sources of energy, wrong, wrong, wrong! CIAL has been named the first airport in the world to be powered solely on solar energy. According to CIAL's official blog post, the 12 MWp solar power plant comprises of exactly 46,150 solar panels laid across 45 acres near cargo complex and is producing 50,000 to 60,000 units of electricity per day to be consumed for all its operational functions, which technically make the airport "absolutely power neutral".

Estimates say that over the next 25 years the airport's green project is going to avoid carbon dioxide emissions from coal fired power plants by more than 3 lakh metric tons, which is equivalent to planting 3 million trees. Now how about that?
