Energy efficient, solar powered LED streetlights are being tested in China in efforts to devise further ways to save energy. Solar panels sit on top of each streetlight allowing solar energy to be collected during the day... the energy is then utilized to power the streetlights during the darkness of night.
Implications - These particular LEDs are way more efficient than their smaller fluorescent lamp counterparts and far superior to conventional lights. It wouldn't be surprising to see a lot of cities moving quickly to adapt this technology into their infrastructure, as I'm sure the amount of energy and money they would save over a long enough period of time would be substantial.
