Question

Why has it become necessary to use renewable energy resources like solar energy etc.?

Answer 1

Hint: Renewable energy is useful energy derived from renewable resources that are regenerated naturally on a human timescale, such as carbon-neutral sources such as sunshine, wind, rain, tides, waves, and geothermal heat. This type of energy source is renewable, unlike fossil fuels, which deplete far quicker than they can be replenished.

Complete answer:
A renewable resource is one that can be used repeatedly and naturally replaced. Renewable energy provides reliable power and fuel diversification, improving energy security and minimising the risk of fuel leaks while also lowering the need for imported fuels. Renewable energy also helps the country's natural resources to be conserved.In India, there is an urgent need to utilise renewable energy resources because:

- Traditional energy supplies are rapidly depleting, necessitating the use of alternate energy sources, such as renewable energy sources, to ensure continued development.
- Government-implemented economic growth plans necessitate a consistent and increasing amount of energy to remain viable.
- Energy consumption in all forms is steadily increasing and outpacing the creation of resources such as coal, petroleum, and other fossil fuels.
- The ecosystem suffers greatly as a result of the smoke and pollution generated by non-renewable resources.
- Renewable energy sources are needed to meet demand while also preserving the environment because they are "Eco-friendly" in nature and limitless.

Given that enough energy to meet the planet's power needs for an entire year reaches the globe from the sun in just one hour, the sun's ability to supply our power needs is enormous. Thus, solar energy is a very important source.

Wind energy works similarly to old-fashioned windmills in that it uses the wind's power to turn a blade. The motion of these blades used to cause millstones to grind together to manufacture flour, but now they power a generator that generates electricity.

Hydroelectric power is similar to wind power in that it is utilised to spin the turbine blades of a generator to generate energy. Hydropower, which is commonly employed in several nations, employs rapidly moving water from rivers or waterfalls to spin turbine blades.

All these factors make it necessary to use renewable energy resources like solar energy etc.

Note: Because most renewable energy methods generate electricity, they are frequently used in tandem with additional electrification, which has numerous advantages: electricity can be converted to heat, mechanical energy may be converted with great efficiency, and it is clean at the point of consumption.
