The photovoltaic effect was first discovered in 1839 by Edmond Becquerel. The hotovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight.

Wood is a renewable resource. Trees can be replanted and grown to maturity in place of those that are cut down. When trees are replanted at same rate as y are cut down, wood will be a renewable resource. Rainforests are said to be non-renewable because y take thousands of years to re-grow.

Dams are used for power generation. The reservoir water is stored at a higher level than turbines, which are housed in a power station. The dam feed water directly to turbines in power station.

Biogas is one of types of bio fuel that is produced from decomposition of organic waste. Biogas is known as environmentally-friendly energy source since it is converting organic waste into energy. The composition of biogas is as follows: – Methane 50-75%, Carbon dioxide 25-50%, Nitrogen 0-10%, Hydrogen 0-1%.

Ministry of New and Renewable Energy is a ministry of Government of India. The ministry is working to develop renewable energy for supplementing energy requirements of India. It is headquartered in Lodhi Road, New Delhi.

Wind power having capacity 29000 MW holds 56.8%, Solar power having capacity 9500 MW holds 18.5%, Biomass power having capacity 8200 MW holds 16%, Small Hydro power having capacity 4400 MW holds 8.5%.

Cochin International airport, fourth-largest airport in India in terms of international traffic, now runs entirely on solar power. Cochin International Airport became world’s first fully solar powered airport on 18 August 2015.

According to a recent survey large hydro installed capacity was 44.41 GW. The large hydro is administered separately by Ministry of Power and not included in Ministry of New and Renewable Energy.

No, Nuclear Energy is not a Renewable Energy. Nuclear Energy is produced in Nuclear power plant. Nuclear power plant uses uranium as nuclear fuel to generate electricity during nuclear fission reaction. Uranium is a finite resource, so we can’t consider nuclear energy produced by uranium in a nuclear reactor as a renewable energy source.

Muppandal Wind Farm produces 1500 MW of current capacity. Muppandal Wind Farm is second largest onshore wind farm in world. This Wind Farm supplies power to many regions in Tamil Nadu.
