The Department of Energy just gave $100,000 to upstart company Solar Roadways, to develop 12-by-12-foot solar panels, dubbed "Solar Roads," that can be embedded into roads, pumping power into the grid. The panels may also feature LED road warnings and built-in heating elements that could prevent roads from freezing.
Each Solar Road panel can develop around 7.6 kwh of power each day, and each costs around $7,000. If widely adopted, they could realistically wean the US off fossil fuels: a mile-long stretch of four-lane highway could take 500 homes off the grid. If the entire US Interstate system made use of the panels, energy would no longer be a concern for the country.
