Earth day is 48 years today. There’s no better time to raise awareness about renewable energy than today. When renewable energy sources are used, the demand for fossil fuels is reduced. Unlike fossil fuels, non-biomass renewable sources of energy (hydropower, geothermal, wind, and solar) do not directly emit greenhouse gases. The use of renewable energy means, less global warming, improve public health, jobs and many other economic benefits. We really can run the world on renewable energy. SAY YES TO RENEWABLE!
