Powering our globe is being revolutionized by renewable energy. The need for clean energy sources is greater than ever due to rising environmental concerns and technological breakthroughs. This article will explain renewable energy, its types, uses, benefits, and the latest statistics shaping its future.
What is Renewable Energy?
Renewable energy is the power we get from nature—like sunlight, wind, water, and even heat from the Earth. These energy sources are called renewable because they never run out. The sun shines every day, the wind keeps blowing, and rivers keep flowing. That means we can keep using them again and again.
Unlike coal or petrol, which pollute the air and can finish one day, renewable energy is clean and safe for the planet. It helps us make electricity for our homes, schools, and even cars—without causing harm to the environment.
