Which renewable energy source relies on the gravitational pull of the moon and the sun?
Correct Answer: A. Tidal energy
Tidal energy is generated by capturing the kinetic energy from the rise and fall of ocean tides. The gravitational forces of the moon and sun cause these regular movements in sea levels. Coastal regions with large tidal ranges are ideal for this technology.
The 'Bhadla Solar Park', currently the world's largest solar farm by area, is located in which Indian district?
Correct Answer: C. Jodhpur
Bhadla Solar Park is located in the Jodhpur district of Rajasthan. The region is known for its high solar radiation and vast arid land. It covers more than 14,000 acres and powers millions of homes.
Which ministry is primarily responsible for the development of clean energy in India?
Correct Answer: D. Ministry of New and Renewable Energy
The Ministry of New and Renewable Energy (MNRE) oversees all research and policy related to green power. It was established to ensure India achieves its international climate commitments. MNRE manages major schemes like PM-KUSUM and solar park development.
What is the primary disadvantage of wind and solar energy compared to coal power?
Correct Answer: A. Intermittency
Intermittency refers to the fact that wind and solar power depend on weather conditions and time of day. Coal provides a constant 'base load' power that renewable sources cannot yet match without storage. Battery technology is being developed to solve this stability issue.
Which gas is commonly used as a clean alternative to gasoline and is derived from biomass fermentation?
Correct Answer: D. Ethanol
Ethanol is a biofuel produced by fermenting sugars found in crops like sugarcane and corn. India has a national policy to blend ethanol with petrol to reduce crude oil imports. It helps in lowering vehicle emissions and supporting farmers.
What is the name of the first tidal power project proposed in the Gulf of Kutch?
Correct Answer: D. Kalpasar Project
The Kalpasar Project is a proposed multi-purpose dam across the Gulf of Khambhat/Kutch for fresh water and tidal power. It aims to harness the massive tidal potential of the Gujarat coast. If completed, it would be one of the largest tidal energy installations globally.
Which renewable energy technology uses mirrors to focus sunlight onto a small area to generate heat?
Correct Answer: D. Concentrated Solar Power
Concentrated Solar Power (CSP) systems use mirrors or lenses to concentrate a large area of sunlight onto a receiver. The resulting high-temperature heat is used to drive a steam turbine. Unlike PV panels, CSP can sometimes store heat to generate power after sunset.
The 'PM-KUSUM' scheme in India is primarily aimed at which group?
Correct Answer: C. Farmers
The PM-KUSUM scheme aims to provide energy security to farmers through solar-powered pumps. It encourages farmers to install solar plants on barren land and sell surplus power to the grid. This reduces their dependence on expensive diesel for irrigation.
Which country is the global headquarters of the 'International Renewable Energy Agency' (IRENA)?
Correct Answer: C. United Arab Emirates
IRENA is headquartered in Masdar City, Abu Dhabi, in the United Arab Emirates. It is an intergovernmental organization that supports countries in their transition to a sustainable energy future. It provides data and policy advice to its member nations.
What is 'Ocean Thermal Energy Conversion' (OTEC) based on?
Correct Answer: D. Temperature difference in water layers
OTEC uses the temperature difference between cooler deep ocean water and warmer shallow water to run a heat engine. It is a source of renewable energy that is most effective in tropical regions. This technology can provide a continuous supply of electricity.
