Yesterday was Sun Day! Sun Day was proposed by Denis Hayes, an American environmental advocate, and established in 1978 by then-president Jimmy Carter. Celebrated every May 3rd, this annual celebration of the sun was established to help promote solar energy as a viable, environmentally sound energy source. Solar energy is one of the safest ecological energy sources as it does not pollute the environment nor have long-term side effects like fossil fuels. It is comparatively cheaper (especially in the long run) and can give an equal amount of energy to power stations around the globe. But the sun isn’t just a source of power for energy, it also has a positive impact on humans!
