Question

The ultimate source of our energy
(\[1\]) Sun
(\[2\]) Plants
(\[3\]) Electricity
(\[4\]) Wind.

Answer 1

Hint: The capacity of a physical system to accomplish work is defined as energy. Heat, kinetic or mechanical energy, light, potential energy, electrical energy, and other types of energy exist. The ability to work is defined as energy. There are two types of energy sources: renewable and non-renewable. Renewable energy comes from natural processes that replenish themselves on a regular basis, such as solar, wind, ocean, hydropower, biomass, and so on. Non-renewable energy sources are coal, natural gas etc.

Complete answer:
Option \[1\]: The sun is the principal energy source because it provides virtually all of the energy on the planet. Plants and animals use sunlight to make food, and the food we eat comes from plants and animals as well. The fossil fuels we utilise in our daily lives are derived from deceased plants and animals that, like solar energy, had their start in the sun.
So, option \[1\] is correct.
Option \[2\]: Photosynthesis is the process by which a plant's leaves absorb sunlight and combine it with water and carbon dioxide to create the sugars that the plant feeds on.
So, option \[2\] is incorrect.
Option \[3\]: Electrical energy is the energy derived from electron mobility. Electrical energy is a term that is used to describe energy that has been converted from electric potential energy. This energy is provided through an electrical circuit that delivers a combination of electric current and electric potential.
So, option \[3\] is incorrect
Option \[4\]: Wind power, often known as wind energy, is the utilisation of wind turbines to generate mechanical power, which is then used to turn electric generators to generate electricity. When opposed to burning fossil fuels, wind power is a popular sustainable, renewable energy source that has a significantly lower environmental impact.
So, option \[4\] is incorrect.

Hence, Option \[1\] is the correct answer.

Note:
The primary source of energy is the sun. Sunlight is a non-polluting, renewable energy source. It is a free, perpetual, natural supply. It does not pollute the environment. There are no greenhouse gases produced by it. Solar energy is decentralised in most places, allowing for a self-sufficient society. One of the most significant benefits of solar energy is the ability to escape the politics and price instability that are becoming increasingly common in fossil fuel markets. It does not cause the devastation of forests and ecosystems that most fossil-fuel activities do.
