We have a good chance of surviving long enough to colonize the solar system.

While first developed as a practical power source during the 1950s, solar systems were too expensive for mainstream use until the 1970s. Starting from their early use to power Cold War era military satellites, silicon photovoltaic solar cells achieved their first commercial success in places where electricity was not available, such as lighthouses and off-shore oil rigs. #solarsystem#power#electricity#greenenergy#sunlight#solar#lighthouse#ecofriendly
