Based on report from the CNN website:
Hickory Ridge landfill was once a mountain of landfill waste – a scar on the landscape on the outskirts of Atlanta, Georgia.
But now, the former landfill site has been covered with 10 acres of solar panels, to provide green renewable energy
In addition to the solar panels, gas pumps have been driven deep into the ground to collect methane gas, from the mountain of waste as it decomposes, in order to provide another source of energy.
