Question

"The generation of energy through non-conventional sources is the need of the hour for sustainable development." Explain the statement with examples.

Hint:

To ensure a sustainable future, transitioning to renewable energy sources like solar, wind, and hydropower is crucial to meeting global energy needs without damaging the environment.

Answer 1

The growing demand for energy, coupled with environmental concerns, has made non-conventional sources of energy an essential part of the sustainable development agenda. Non-conventional sources of energy, also known as renewable or alternative energy, include:
Solar Energy: Solar power harnesses energy from the sun using solar panels. It is one of the cleanest and most abundant sources of energy, with applications in both residential and industrial sectors.
Wind Energy: Wind turbines convert the kinetic energy of wind into electricity. Wind power is becoming increasingly popular, especially in coastal and rural areas with strong wind resources.
Hydropower: The energy generated from flowing water in rivers or dams is known as hydropower. It is widely used for electricity generation and is considered a reliable source of renewable energy.
Biomass Energy: Biomass, such as wood, agricultural waste, and animal waste, can be converted into energy through combustion or biochemical processes. It serves as an alternative to fossil fuels for heating and electricity generation.
Geothermal Energy: This involves harnessing heat from within the earth’s crust to generate electricity and provide direct heating. Geothermal energy is particularly useful in regions with high tectonic activity. The need for non-conventional energy sources is driven by concerns over climate change, environmental degradation, and the finite nature of fossil fuels. Renewable energy provides a sustainable and clean alternative to traditional energy sources, helping reduce carbon emissions and promoting environmental conservation.
