Conservation and Environmental Impact Issues
Large tracts of undeveloped land too often coincide with sensitive or protected areas or protected species. Often the presence of a single protected species of plant or animal can halt or completely alter the development plans for a solar farm, and for example in California, the evidence of single endangered burrowing owl halted the development of a solar farm project worth hundreds of millions. Thin films are especially bad as they really require the land to be completely covered to get a useful watts/acre ratio.
