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

Due to escalating energy demands and environmental imperatives, non-conventional energy sources are now a cornerstone of sustainable development strategies. These sources, also termed renewable or alternative energy, comprise:
Solar Energy: This method captures solar radiation using photovoltaic panels to produce electricity. It's a leading clean and abundant energy option for both domestic and industrial use.
Wind Energy: Wind turbines transform wind's kinetic energy into electrical power. Wind energy is increasingly adopted, especially in windy coastal and rural locales.
Hydropower: Derived from the kinetic energy of moving water, typically in rivers or dams, hydropower is a major contributor to electricity generation and a dependable renewable option.
Biomass Energy: Organic matter like wood and agricultural or animal waste can be processed through combustion or biochemical means to yield energy. It functions as a substitute for fossil fuels in heating and power generation.
Geothermal Energy: This approach utilizes the Earth's internal heat for electricity production and direct heating. It is particularly effective in geologically active regions.The urgency for non-conventional energy stems from climate change anxieties, ecological damage, and the limited supply of fossil fuels. Renewable energy offers an environmentally sound and sustainable alternative to conventional power sources, aiding in the reduction of greenhouse gas emissions and fostering ecological preservation.
