Until now, the latest and greatest way to sustainable energy was high-altitude wind turbines.
But multiple companies have made serious investments toward delivering solar energy from space within the next decade.
Major U.S. companies are aggressively researching the technology to beam the energy from one big satellite and then transmit the power back to Earth.
This would be a major breakthrough in not only the science field, but the sustainability field because unlike other sources of renewable energy, space solar power is not limited by geography. With the satellites orbiting nonstop, the power grid can be continuously fed.
