Tamil Nadu has the country’s biggest onshore wind farm which is called the Muppandal Wind Farm. Located in the district of Kanyakumari, it features several wind turbines varying from 200KW to 1,650KW. It contains a total capacity of 1500 MW which is considered about 20% of wind energy across India. This project was developed by Tamil Nadu Energy Development Agency. The wind farms within this project have varying installed capacities and feature turbines from various manufacturers, including Vestas, NEPC India, AMTL, TTG and Suzlon.

Solar thermal power plants are electricity generation plants that utilize energy from the Sun to heat a fluid to a high temperature. This fluid then transfers its heat to water, which then becomes superheated steam. This steam is then used to turn turbines in a power plant, and this mechanical energy is converted into electricity by a generator.

Piezoelectric devices are used to generate electricity on highways which have thousands of cars driven on it each day.

Piezoelectricity is the electric charge produced by certain crystals when a mechanical stress is applied. First demonstrated in 1880 by the brothers Pierre and Jacques Curie, the piezoelectric effect has only begun to have practical applications in the past three decades.

Piezoelectric crystals are embedded beneath a layer of asphalt. As cars drive over the road, the wheels exert a force that causes these crystals to deform and generate electrical energy. This energy can then be used to power street lights or can be stored in batteries for later use.

Solar power has replaced wind power to become the largest renewable energy technology in India.

the pace at which solar power capacity has grown has been stellar. Ten years back, solar power capacity was just 18 megawatts, while wind power capacity was at 13 gigawatts (13,000 megawatts). So, during the last ten years, solar power capacity has grown 2,150 times while wind power capacity has grown three times.
