Wind energy is a type of renewable energy that is produced by the movement of air. This movement, or wind, occurs due to the uneven heating of Earth’s surface by the sun. Because the Earth is curved and has different surfaces like oceans, forests, deserts, and mountains, some areas absorb more heat than others. As a result, air in warmer regions becomes lighter and rises, while cooler, heavier air moves in to replace it. This movement of air creates wind.

The sun plays a key role in this process, but the energy produced is not classified as solar energy. Solar energy refers to the direct use of sunlight, such as in solar panels. Wind energy, on the other hand, is an indirect form of solar energy because it relies on solar heat to drive atmospheric circulation.

Biomass energy comes from organic materials such as wood, crop waste, or animal waste. It is stored chemical energy and is not directly related to the uneven heating of the Earth.

Wind turbines convert the kinetic energy of moving air into mechanical or electrical energy. This energy is clean, renewable, and widely used across the globe to reduce dependence on fossil fuels. Wind farms are now a common feature in many countries, often located in open plains or coastal areas where winds are stronger and more consistent.

Understanding that wind energy is caused by uneven heating of Earth’s surface is part of basic environmental science. It shows how natural processes can be harnessed to produce useful energy without damaging the environment.
