Philadelphia is becoming well known for its green activities ...
including solar powered compacting trash bins (the BIG BELLY) that can signal when they
are full and need to be emptied.
They are also upgrading standard
traffic signals with ones that contain LED light "bulbs".
LEDs are
even more energy efficient and longer lasting than CFBs - and do not
contain any mercury.
" ... funding through the U.S. Department of Energy’s Energy Efficiency
and
Conservation Block Grant (EECBG). ... reducing energy use and costs,
... and furthering the City’s sustainability priorities."
"Replacing 85,000 traffic lights with new,
low energy LED lights."
