Which Indian state has the highest potential for geothermal energy according to the Geological Survey of India?
Correct Answer: D. Ladakh
Ladakh, particularly the Puga Valley, has the highest proven potential for geothermal power in India. The region features numerous hot springs and high-temperature underground reservoirs. India's first geothermal power plant is currently being developed here.
What is the primary benefit of 'Small Hydro Power' (SHP) over large dams?
Correct Answer: D. Minimal environmental displacement
Small Hydro projects have a capacity of up to 25 MW and do not require large reservoirs. They cause minimal damage to the ecosystem and do not lead to large-scale displacement of people. They are ideal for providing electricity to remote hilly areas.
Which sector is the target of the 'FAME India' scheme?
Correct Answer: A. Electric Vehicles
The FAME India scheme (Faster Adoption and Manufacturing of Electric Vehicles) promotes the use of clean transport. It provides subsidies for the purchase of electric and hybrid cars and buses. This initiative helps in reducing air pollution in major cities.
What is 'Photovoltaic effect' primarily associated with?
Correct Answer: D. Solar panels
The photovoltaic effect is the process by which a material converts light photons directly into electrical voltage. This is the fundamental physical principle behind the working of solar panels. It was first observed by Edmond Becquerel in 1839.
Which of the following is considered a 'Second Generation' biofuel?
Correct Answer: C. Non-food biomass (cellulosic)
Second generation biofuels are produced from non-food sources like wood, grass, or agricultural residues. They are more sustainable because they do not compete with food crops for land. This technology is essential for reducing the carbon footprint of the transport sector.
Which island territory of India is being developed as a major hub for offshore wind energy?
Correct Answer: D. Andaman and Nicobar
The Andaman and Nicobar Islands have high wind speeds suitable for offshore wind installations. The government is focusing on these islands to replace diesel generators with renewable energy. This transition is vital for the fragile ecology of the island chain.
What is the function of an 'Inverter' in a rooftop solar system?
Correct Answer: D. Converts DC to AC
Solar panels generate Direct Current (DC) electricity, but home appliances run on Alternating Current (AC). An inverter converts the DC power from the panels into usable AC power for the household. It is a critical component of every grid-connected solar installation.
Which country currently has the largest cumulative capacity of renewable energy globally?
Correct Answer: C. China
China leads the world in total installed capacity of solar, wind, and hydropower. It has invested heavily in green technology to reduce its dependence on coal. This massive scale of production has helped lower the global cost of solar panels.
What is 'Net Metering' in the context of renewable energy?
Correct Answer: B. Billing mechanism for solar power users
Net metering allows solar power owners to feed excess electricity back into the grid. The user is only charged for the 'net' amount of electricity consumed from the utility company. It encourages individuals to install rooftop solar systems by making them financially viable.
Which state in India was the first to implement a dedicated 'Solar Power Policy'?
Correct Answer: B. Gujarat
Gujarat was the pioneer in launching a comprehensive solar policy in 2009. This initiative led to the development of the Charanka Solar Park, which was then the largest in Asia. Many other states later followed the Gujarat model to boost their green energy output.
