Renewable energy refers to any energy source that can be replenished naturally within a short time frame, making it an infinitely sustainable resource. Unlike fossil fuels, renewable energy sources such as wind power, solar energy, hydropower, and biomass do not generate greenhouse gases or other harmful pollutants that contribute to climate change.
Wind power harnesses the power of wind to generate electricity, while solar energy converts the sun’s energy into electricity through photovoltaic panels or thermal collectors. Biomass energy uses organic materials such as wood, agricultural waste, and municipal solid waste to generate heat and electricity. Hydropower relies on the power of moving water to generate electricity.
Renewable energy is becoming increasingly popular due to its environmental benefits and declining costs. It has the potential to reduce the world’s reliance on fossil fuels, creating a more sustainable and resilient energy system. However, significant investments in research and development are needed to further improve the efficiency and affordability of renewable energy technologies.
