The world's first fully solar-powered airport is located in which Indian city?
Correct Answer: B. Kochi
Kochi International Airport in Kerala became the world's first airport to run entirely on solar energy in 2015. It has a large solar power plant within its premises. This project won the United Nations 'Champion of the Earth' award.
What is the primary goal of the 'National Green Hydrogen Mission' launched by India?
Correct Answer: B. To make India a global hub for green hydrogen
The mission aims to make India a leading producer and exporter of green hydrogen. Green hydrogen is produced by using renewable energy to split water into hydrogen and oxygen. It is seen as a key fuel for a carbon-neutral future.
Which type of solar energy system uses mirrors to focus sunlight onto a specific point?
Correct Answer: A. Concentrated Solar Power (CSP)
Concentrated Solar Power (CSP) uses mirrors to focus a large area of sunlight onto a receiver. This high heat is then used to produce steam and generate electricity. This method is different from the direct conversion used in solar panels.
The energy of the wind is captured using which of the following?
Correct Answer: B. Wind turbines
Wind turbines are used to convert the kinetic energy of the wind into mechanical power. This power is then converted into electricity by a generator. Modern wind turbines are usually installed in large groups called wind farms.
Which of the following is a byproduct of generating energy through biomass?
Correct Answer: B. Bio-fertilizers
Generating energy from biomass often produces nutrient-rich organic residue. This residue can be used as high-quality bio-fertilizer for agriculture. It creates a circular and sustainable waste-to-wealth system.
What is the renewable energy target set by India for the year 2030?
Correct Answer: C. 500 GW
India has committed to achieving 500 GW of non-fossil fuel energy capacity by 2030. This is a key part of India's climate goals announced at COP26. The target includes power from solar, wind, hydro, and biomass.
Which state is known for its large-scale 'Floating Solar' power plants?
Correct Answer: A. Telangana
Telangana is home to some of India's largest floating solar power plants, such as the one at Ramagundam. Floating solar plants are built on water bodies like reservoirs. They help in reducing water evaporation while generating clean energy.
What is the primary disadvantage of solar and wind energy?
Correct Answer: C. They are intermittent (depend on weather)
Solar and wind energy are intermittent because they depend on sunlight and wind availability. This makes it challenging to maintain a steady supply of power without batteries. Energy storage systems are being developed to address this issue.
The term 'Blue Energy' is often associated with which source?
Correct Answer: B. Osmotic energy from seawater
Blue energy is the energy retrieved from the difference in salt concentration between river water and sea water. It is also known as osmotic power. This is a sustainable source of energy that can be captured at river mouths.
Which Indian state has the second-highest installed solar power capacity currently?
Correct Answer: A. Gujarat
While Rajasthan leads, Gujarat holds the second position in installed solar capacity in India. The state has been a pioneer in implementing solar policies and building solar parks. Gujarat's dry climate and clear skies make it highly suitable for solar power.
