Are some solar projects no longer ‘green’?
Solar companies proposing large power plants in the Mojave Desert are facing opposition from conservationists. They say a rush to build solar here threatens to tear up large tracts of desert habitat and open space. (...) Conservationists worry that a plan for the Mojave desert will upset species’ habitats (...) Desert’s defenders argue that solar panels should be located on city rooftops rather than pristine lands.

Solar power for toxic waste sites?
Why not set up utility-scale, renewable energy in polluted zones instead?
That's what the Environmental Protection Agency is proposing. (...) 850,000 acres it has cleaned up, among 15 million contaminated acres total, are exceptional destinations for clean-power companies, in part due to the low cost and existing infrastructure there. Plus, brownfields, former mines, etc are unattractive for most commercial and residential development, especially in rural areas.
