Strong enough to fry eggs from 93 million miles away, the sun is an incredibly powerful energy source. According to researchers, the availability of solar energy far exceeds global energy consumption. That's why TVA collects solar power with photovoltaic panels to transform into usable electricity. When rays of sunshine strike a solar panel, they give energy to electrons inside it, creating an electric current. The energy from solar power will be small at first, but TVA plans to grow the Green Power Switch Program's solar component.
