Awareness of environmentally friendly energy use today is increasingly flourishing. Accompanied with the low price of renewable energy sources such as solar panels one of which also contribute to the renewable energy campaign. Example one concrete step movement use of renewable energy sources conducted by Cochin International Airport in southern India. Seventh busiest airport in India was crowned as the first international airport which is 100% of its electricity needs met by solar panels.
To meet the electricity needs of the airport, the airport management pointed to a German company, Bosch, to build a solar power plant on vacant land measuring 45 acres located near the international cargo terminal of the airport. With a total of approximately 10,000 solar panels are used, this self-contained power plant capable of supplying 48,000 to 50,000 kilowatts of electricity to meet the electricity needs of the airport each day. Even the amount of energy is still surplus and still able to support the needs of the electricity network in the area around the airport.
Construction of solar power plants this independent cost US $ 9.3 million, equivalent to 121 billion rupiah. With the cost of the airport management hoped would never buy electricity from its India up to six years into the future. In addition, the solar power plants contributed to reducing carbon dioxide emissions of 300,000 metric tons of coal-fired power plants of up to twenty-five years into the future.
