Mayor Antonio Villaraigosa, along with President Bill Clinton, will retrofit LA with 140,000 LED streetlights starting this June. The initiative will save the city $48 million, and reduce carbon emissions by 197,000 tons.

Residents in Lemgo, Schwelentrup-Doerntrup, and Rahden pay up to 10 cents a minute for lighting after 11 pm under the plan, called Dial4Light. People use cell or landlines to call the city, give their route and time period when light is needed, and then a computer system triggers the lights to turn on along the path.
The plan is a creative effort to save energy, but could result in a whole different set of problems.
