Solar energy is a big trend these days and for a good reason! It is a completely free energy source the correct devices can capture in abundance. The sun is 90 million miles away, but it takes less than ten minutes for light to travel to Earth, and the planet receives nearly 1,400 watts of direct solar radiation per square meter. In the past decade, the cost of solar panels has reduced by 80%. Once installed, solar panels are easy to maintain and expected to last about 25 years. In the US, most homes consume about 11,000 kilowatt-hours of energy each year. To power a home with 100% solar energy, you would have to install 30 250-watt solar panels and capture four hours of sunlight per day. To power the entire Earth, we need 191,000 square miles of solar panels. With nearly 60 million square miles on Earth, there's room to spare!
