Most of these projects require a lot of water, and all require "clear cutting" the desert to prevent weeds and pests.
How ironic that this so called "green revolution" has taken the irresponsible direction of so much environmental destruction. Why not just use the countless rooftops and vacant space of the millions of developed urban acres in the southwest? Could it be that urban environmental planning is considered too costly? We are baffled by this because it defeats the purpose of green.
As we make the changes to our economy and our energy infrastructure that we have to make, we have to take care of our existing resources, such as the great deserts. For no other reason than we don't really know everything about them. For example, it's been learned recently that:
Desert plants and soils store carbon better than most northern forests. Desert plants are masters of storing carbon. CAM ("crassulacean acid metabolism") plants are plants that use certain special compounds to gather carbon dioxide (CO2) during photosynthesis.
Don't want to lose that while trying to eliminate carbon from our energy system, do we? We have a lot of carbon already in the atmosphere that needs sucking up. What else is this desert flora and fauna doing for Earth that we haven't learned yet? Do we want to take the chance of upsetting yet more of the balance? We need to take a lot of care as we move forward with whatever large-scale energy projects we undertake.
I recommend this article, and I'd be interested to hear your thinking about how to avoid bad consequences while achieving energy independence.
