Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → With the help of photovoltaic cells
Photovoltaic cells use special materials to capture solar energy and convert it into electricity.
Option (1) With the help of advanced photosynthesis — Incorrect. Photosynthesis is how plants use solar energy to make food.
Option (2) With the help of photovoltaic cells — Correct. These cells turn sunlight into electricity.
Option (3) With the help of solar alliance — Incorrect. The International Solar Alliance (ISA) is an international body that India leads.
NCERT (2026-27): “7.5 Strategies for Sustainable Development … Plants use solar energy to perform photosynthesis. Now, with the help of photovoltaic cells, solar energy can be converted into electricity. These cells use special kind of materials to capture solar energy and then convert the energy into electricity. This technology is extremely useful for remote areas and for places where supply of power through grid or power lines is either not possible or proves very costly. This technique is also totally free from pollution. In recent years India is taking efforts to increase the power generation through solar. India is also leading an International body called International Solar Alliance (ISA).” |
