CSP plants that use wet-recirculating technology with cooling towers withdraw between and gallons of water per megawatt-hour of electricity produced.

Hinrichs R.A., Kleinbach M.H. Energy: Its Use and the Environment

CSP plants with once-through cooling technology have higher levels of water withdrawal, but lower total water consumption because water is not lost as steam.

Dry-cooling technology can reduce water use at CSP plants by approximately 90 percent [ 3 ]. However, the tradeoffs to these water savings are higher costs and lower efficiencies.

In addition, dry-cooling technology is significantly less effective at temperatures above degrees Fahrenheit. Many of the regions in the United States that have the highest potential for solar energy also tend to be those with the driest climates, so careful consideration of these water tradeoffs is essential. Hazardous Materials The PV cell manufacturing process includes a number of hazardous materials, most of which are used to clean and purify the semiconductor surface.

These chemicals, similar to those used in the general semiconductor industry, include hydrochloric acid, sulfuric acid, nitric acid, hydrogen fluoride, 1,1,1-trichloroethane, and acetone. The amount and type of chemicals used depends on the type of cell, the amount of cleaning that is needed, and the size of silicon wafer [ 4 ].

Workers also face risks associated with inhaling silicon dust. Thus, PV manufactures must follow U. Thin-film PV cells contain a number of more toxic materials than those used in traditional silicon photovoltaic cells, including gallium arsenide, copper-indium-gallium-diselenide, and cadmium-telluride[ 5 ].

If not handled and disposed of properly, these materials could pose serious environmental or public health threats.

However, manufacturers have a strong financial incentive to ensure that these highly valuable and often rare materials are recycled rather than thrown away. Life-Cycle Global Warming Emissions While there are no global warming emissions associated with generating electricity from solar energy, there are emissions associated with other stages of the solar life-cycle, including manufacturing, materials transportation, installation, maintenance, and decommissioning and dismantlement.

Most estimates of life-cycle emissions for photovoltaic systems are between 0. Most estimates for concentrating solar power range from 0. In both cases, this is far less than the lifecycle emission rates for natural gas 0. Renewable Energy at Mining Sites.

The text can be used in physics, technology, physical science, and environmental science courses for non-science majors. This paper examines energy use in Canada by region and sector, focusing on four sectors most relevant to civil engineering activities: residential, commercial—institutional, construction, and transportation.

However, the tradeoffs to these water savings are higher costs and lower efficiencies. The relationships between energy consumption and infrastructure design are analysed. Land Use Depending on their location, larger utility-scale solar facilities can raise concerns about land degradation and habitat loss.
