The Moon as a source of energy. This is the vision of Tokyo-based construction company Shimizu Corporation Group, which has come up with a truly ambitious plan to build a solar power plant on Earth's satellite that would supply electrical energy to our planet. A ring of solar panels would encircle the entire Moon. Its length would therefore be 11 thousand kilometers, and its output would be approximately 13,000 terawatts of electrical energy, which is almost triple the annual electricity production of the United States of America. Energy from the solar panels would be transported from the Moon to Earth using microwave or laser transmitters, and then processed into electrical current at ground stations. 
At first glance, this whole thing might look like a plot for a science fiction novel, but scientific progress is advancing by leaps and bounds, and our first somewhat uncertain steps in space are long behind us. So the idea that Earth will put a solar ring on the Moon may not be so unrealistic after all. You can learn more in this video. red
