Solar power development in US Southwest could threaten wildlife

Environmental impacts of planned installations largely unknown

Government agencies are considering scores of applications to develop utility-scale solar power installations in the desert Southwest of the United States, but too little is known to judge their likely effects on wildlife, according to an article published in the December 2011 issue of BioScience.

Although solar power is often seen as a "green" energy technology, available information suggests a worrisome range of possible impacts. These concern wildlife biologists because the region is a hotspot of biodiversity and includes many endangered or protected species, notably Agassiz's desert tortoise. It and another tortoise, Morafka's, dig burrows that shelter many other organisms.

The article, by Jeffrey E. Lovich and Joshua R. Ennen of the US Geological Survey's Southwest Biological Science Center, notes that solar energy facilities are poised for rapid development and could cover hundreds of thousands of hectares. Assessments of their effects should count both onsite and offsite effects and include construction and decommissioning as well as the operational phase, the authors point out. Yet there are to date almost no peer-reviewed studies on the impacts of solar installations specifically.

The authors' initial attempt to catalogue the foreseeable effects draws attention to habitat fragmentation caused by roads and power lines, which could restrict gene flow, as well as the production of large amounts of dust through ground-disturbance. Solar plants are also expected to release pollutants such as dust suppressants, rust suppressants, and antifreeze, both in routine operation as well as through spills. They will predictably generate heat, electromagnetic fields, noise, polarized light, and possibly ignite fires. Evaporative ponds, which concentrate toxins, may be used and are a recognized hazard to wildlife. Because wet-cooled turbines need to be supplied with large amounts of water, developers are leaning toward using dry-cooled turbines, but these have a larger "footprint" than wet-cooled ones.

The dearth of reliable information indicates an urgent need for careful, controlled, pre- and post-construction studies of the effects of solar power plants in the Southwest, Lovich and Ennen argue. Such studies could attempt to determine information useful for optimally siting the plants, such as whether damage is minimized if they are concentrated in a few places or dispersed, as well as suggest preferred locations and mitigation possibilities.

BioScience, published monthly, is the journal of the American Institute of Biological Sciences (AIBS). BioScience publishes commentary and peer-reviewed articles covering a wide range of biological fields, with a focus on "Organisms from Molecules to the Environment." The journal has been published since 1964. AIBS is an umbrella organization for professional scientific societies and organizations that are involved with biology. It represents nearly 160 member societies and organizations.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
