Space-Based Solar Power Next Energy Frontier

The idea of using satellites to beam solar power down from space is nothing new—the Department of Energy first studied it in the 1970s, and NASA took another look in the ’90s. The stumbling block has been less the engineering challenge than the cost.

A Pentagon report released in October could mean the stars are finally aligning for space-based solar power, or SBSP. According to the report, SBSP is becoming more feasible, and eventually could help head off crises such as climate change and wars over diminishing energy supplies.

The new report imagines a market-based approach. Eventually, SBSP may become enormously profitable—and the Pentagon hopes it will lure the growing private space industry.
