Which state in India is home to the world's first fully solar-powered airport?
Correct Answer: A. Kerala
The Cochin International Airport in Kerala became the world's first fully solar-powered airport in 2015. It utilizes a large dedicated solar farm to meet all its electricity needs. This project serves as a global model for sustainable aviation infrastructure.
What is the primary energy source used in a 'Geothermal' power plant?
Correct Answer: C. Earth's internal heat
Geothermal energy is derived from the heat stored within the Earth's crust. This heat originates from the formation of the planet and the radioactive decay of minerals. It provides a constant and reliable source of clean electricity.
Which Indian state has the highest installed capacity of wind energy as of recent official data?
Correct Answer: D. Tamil Nadu
Tamil Nadu leads India in wind power generation due to its favorable coastal geography. The state hosts the Muppandal wind farm, which is one of the largest in Asia. Strong seasonal winds in the region ensure high energy output.
In a hydroelectric plant, what type of energy is directly converted into mechanical energy by the turbine?
Correct Answer: A. Kinetic energy
The kinetic energy of flowing or falling water turns the blades of the turbine. This rotation then drives an electrical generator to produce power. Large dams are typically built to store water and control this energy flow.
The 'International Solar Alliance' (ISA) was launched jointly by India and which other country?
Correct Answer: C. France
India and France launched the ISA during the COP21 summit held in Paris in 2015. The alliance aims to promote solar energy usage among 'sunshine' countries. Its headquarters is located in Gurugram, India.
What chemical element is the most common semiconductor material used in solar photovoltaic cells?
Correct Answer: D. Silicon
Silicon is the primary material used in solar cells due to its excellent semiconducting properties. It is abundant in nature and can effectively convert sunlight into electricity. Most modern solar panels are made using crystalline silicon.
Which term refers to the organic matter that can be converted into fuel through chemical or biological processes?
Correct Answer: A. Biomass
Biomass includes plant materials, agricultural waste, and animal manure used as energy sources. It can be burned directly or converted into liquid biofuels like ethanol. This source is considered renewable because plant life can be regrown.
The 'Kurnool Ultra Mega Solar Park', one of the largest in the world, is located in which state?
Correct Answer: A. Andhra Pradesh
The Kurnool Solar Park is situated in the state of Andhra Pradesh. It has a massive capacity and significantly contributes to India's green energy targets. The park utilizes thousands of acres of land to house solar panels.
Which color of hydrogen is produced through electrolysis powered by renewable energy sources?
Correct Answer: C. Green Hydrogen
Green hydrogen is the cleanest form of hydrogen produced with zero carbon emissions. It uses renewable power like solar or wind to split water into hydrogen and oxygen. It is seen as a crucial fuel for decarbonizing heavy industries.
What is the main component of Biogas produced from anaerobic digestion?
Correct Answer: D. Methane
Methane is the primary combustible gas found in biogas, usually making up 50-75% of its volume. It is produced when bacteria break down organic matter in the absence of oxygen. Biogas is widely used for cooking and power generation in rural areas.
