Green energy refers to renewable energy sources that are environmentally friendly and sustainable, such as wind, solar, hydro, geothermal, and biomass. These sources of energy produce little to no greenhouse gases and have a minimal impact on the environment compared to fossil fuels. The use of green energy has become increasingly important in the fight against climate change, as it offers a viable alternative to non-renewable energy sources that contribute to the depletion of natural resources and the production of harmful emissions. By investing in green energy, we can reduce our dependence on fossil fuels, mitigate the effects of climate change, and promote a cleaner, more sustainable future.
