Industrial-scale solar power generation is economically feasible only because recent policy has brought massive taxpayer-funded subsidies to the table. Ironically, many of the names behind Big Solar that are taking advantage of this policy are familiar from the realms of of Big Oil (BP and Chevron) and big bailouts (Goldman Sachs and Morgan Stanley).
With 253 million acres in BLM-managed lands alone, it may seem that the public lands, and their potential for use, are endless. Yet much of this area is already damaged or fragmented by mining, urban encroachment, oil and gas operations, livestock grazing, motorized recreation, and other uses. Large, contiguous areas that retain their ecological integrity are increasingly rare: these are some of the areas most acutely threatened by large-scale uses such as industrial solar.
Pass this information along to your friends and networks, so we can get our message spread far and wide and get renewable energy policy turned toward a real solution to the climate crisis.
The United States is wasting billions of dollars of American Recovery and Reinvestment Act (ARRA) cash grants and loan guarantees on very large, high-cost, high-environmental-impact, transmission-dependent desert solar thermal power plants that will be obsolete before they generate a single kilowatt-hour of electricity.
A solar strategy that would have been stateof-the-art in the 1990s, prior to the advent of low-cost solar photovoltaic (PV) power, is now being executed. This is a victory for the broad government, utility, and environmental organization support that solar thermal technology has gained over the last few decades. It is also a victory for the lobbying power of this coalition over economic common sense. Solar thermal has lost the cost-effectiveness race to solar PV. The federal government has not yet absorbed the significance of this important development.

Here we summarize concerns regarding the environmental impacts of massive solar project infrastructure development in the desert. This summary is focused on California, where many projects are in process on public lands. Much of the impetus for this large number of projects comes from California’s goal of meeting 33% of its energy needs through centralized renewable energy generation — i.e., a 33% “renewable portfolio standard (RPS)” by 2015. We also include some discussion of impacts in Colorado’s San Luis Valley, another area where industrial-scale solar projects are proposed on both private and public land. Many of the impacts in these states can be extrapolated to other states.
Our deserts are irrigated by water that fell thousands of years ago, covered in vegetative assemblages that have been developing for longer than recorded human history, and some of the individual plants in them are older than the oldest bristlecone pines. Once altered, those plant communities may never return to their original state even under optimal conditions. If the desert’s aquifers and vegetative communities are forever changed, the animal wildlife that has evolved dependence on local springs, plant habitat and edible vegetation will suffer. Hundreds of thousands of acres in the desert are being studied as possible alternative energy sites. Given the permanent damage that would result from industrial energy development in desert wildlands, it’s time we stopped calling such development “renewable energy.”
