What is Renewable Energy?
Renewable energy is defined as energy derived from natural sources that replenish themselves at a higher rate than they are consumed. Solar, wind, water, and geothermal heat are prime examples of these inexhaustible resources. Unlike fossil fuels, which are finite and contribute to greenhouse gas emissions, renewable energy sources offer a clean and sustainable alternative. The escalating climate crisis, coupled with volatile fossil fuel markets, has underscored the critical importance of transitioning to renewable energy. This transition is not merely an environmental necessity but also an economic opportunity, fostering job creation and technological advancement.
