Photovoltaics Cut Emissions

Even though making photovoltaic solar cells has a negative impact on the environment, over the lifecycle of the solar cells they more than make up for that impact, according to this post in DailyKos (see excerpt below):
The estimated energy payback time (EPBT) for PV ranges from 6 years to 1.1 years, depending upon the type of PV, the insolation, and the installation. PV panels are usually rated to have a lifetime of 25 to 30 years. Now you know what to say when anybody questions whether PV's produce more energy than it takes to make them.
