This is the dumbest thing that atmosfear has ever posted on CD ever and is just him giving into some stupid ass conservative BS propaganda.
Adding solar panels in a location would be a one-time change in albedo, and if one considers current amorphous Si technology panels' efficiency, it would be quite act as a increase in globall warming. However, changing the albedo of a portion of land is like a one time addition of carbon into the atmosphere. You don't have to continuously warm the atmosphere per amount of electricity generated. Furthermore, as solar panel efficiencies increase, the amount of global warming from the panels' prescence would decrease. Also, of course to make solar panels now requires electricity, and that comes from burning fossil fuels, but it's just the necessary start to a bootstrapping process.
As for wind power, yeah if affects the climate if turbines cover massive areas of the globe, on the order of ~10%. But even then studies suggest that its impact on the global climate would be far less than that of other human activities such as deforestation or burning fossil fuels, yes not just coal but also petroleum...
The concern would be over local climate and ecological effects more than global ones. Better turbine design can prevent things like bird death due to turbines or turbulence in the turbines' wakes.
What sorts of PV's are these? The only materials I can think of that could be used in PV's with Cd or As are things like CdZe and III-V semiconductors like GaAs or InAs, and I wasn't aware there was any real potential for making marketable solar cells out of these.
Also by girlfriend, I take it you mean a rough job named Mark?
EDIT: Okay I take that back, I HAVE heard of GaAs and other III-V semiconductors used in solar cells, in fact with the highest reported efficiencies ever, but last I heard they were so prohibitively that they couldn't be used practically.
