As long as humans live on Earth, the sun will be shining. So from our standpoint, solar energy is effectively endless in its availability.
The sun delivers more total energy to the Earth every second than we use in a year. Additionally, solar power generates far less pollution than "dirty" power does when it is produced or consumed. By expanding solar power and decreasing reliance on fossil fuels, carbon emissions worldwide could be reduced significantly.
Because sunlight isn't extracted from the land like fossil fuels, it also has less environmental impact. Fossil fuel extraction can cause significant problems. In 2010, BP's deep sea oil drilling disaster released 3.19 million barrels of oil into the Gulf of Mexico1, harming marine ecosystems. Coal mining in Appalachia has defaced some of the Earth's oldest mountains, as well as causing detrimental health effects in neighboring areas. In comparison, solar energy comes at very little environmental cost.
Solar Energy Has Economic Benefits
Along with its impressively low environmental costs, the solar power industry can also be economically beneficial.
Reliance on foreign fossil fuel supplies has caused global economic and political quandaries in the past, a problem that could be relieved by renewable energy. On a smaller scale, using solar panels at home can help reduce your electric bill significantly, along with decreasing your carbon footprint. They also add value to your property, making them a worthwhile investment.
As the world gradually moves to decrease humanity's reliance on environmentally devastating fossil fuels, solar power provides an efficient and economical "green" solution. Even among renewable energy resources, solar power stands as one of the cleanest technologies available.
