Wind energy

Definition

Wind energy is the process of harnessing the kinetic energy generated by wind through turbines to produce electricity. This renewable energy source is considered one of the most sustainable and environmentally friendly alternatives to fossil fuels, playing a crucial role in the transition towards low-carbon technologies.

5 Must Know Facts For Your Next Test

1. Wind energy is one of the fastest-growing sources of electricity in the world, significantly contributing to reducing greenhouse gas emissions.
2. Onshore wind farms are typically less expensive to build and maintain compared to offshore wind farms, but offshore farms can generate more power due to stronger winds.
3. Wind energy has the potential to provide more than 20% of global electricity needs by 2030 if investments and technology continue to advance.
4. Wind turbines have a lifespan of around 20-25 years, after which they can be decommissioned or repowered with newer technology.
5. The implementation of wind energy contributes to job creation in manufacturing, installation, and maintenance sectors.
