Solar energy offers the highest global potential for electricity generation among renewable energy sources1, and is therefore an important technology for both, climate change mitigation, and the development of a low carbon economy.
The counter application found throughout our site, illustrates an important environmental benefit of First Solar module technology by providing cumulative carbon displacement information since the company began commercial production. The purpose is to communicate carbon displacement from solar deployment in the form of common equivalent measures, including homes powered, cars removed, and trees planted, demonstrating the positive environmental impacts of solar energy.
First Solar has prepared a more in-depth technical report that elaborates on the assumptions and methodology behind the worldwide averages supporting displaced CO2 emissions.
While energy security and climate change have been important drivers for renewable energy adoption, water security provides an additional driver. For example in the United States, thermoelectric power plants have recently accounted for over 40% of total freshwater withdrawals, even more than for agriculture. This energy-water nexus associated with traditional energy sources can be a potential concern, particularly in water-stressed regions. Because solar PV uses little to no water during operation, it provides a potential path forward for addressing the energy-water nexus.
The counter application found throughout our site, illustrates an important environmental benefit of First Solar module technology by providing cumulative water displacement in metric tons since the company began commercial production. The purpose is to communicate water displacement from solar deployment based on avoided operational water consumption by thermal power stations with cooling towers (1.33 m3/MWh; Vassolo and Döll, 2005).
First Solar has prepared a more in-depth technical report that elaborates on water displacement over the entire life cycle of PV electricity.
In 2013, First Solar participated in the Carbon Disclosure Project (CDP) as part of our ongoing commitment to environmental responsibility and transparency. First Solar received a Carbon Disclosure Score of 77 (max 100) and a Carbon Performance Band C rating; placing within the top quartile of all S&P 500 respondents. By the end of 2012, we reported that 7GW of PV solar modules produced by First Solar are being used to displace approximately 4.5 million metric tons of CO2 emissions per year throughout their 25+ year product lifespan. By producing eco-efficient PV power systems, First Solar is displacing more than three times the amount of greenhouse gas emissions from its company-wide operations. In addition to providing a clean and reliable renewable energy product, First Solar continuously strives to reduce the carbon impacts of our own operations and activities through increased module and manufacturing efficiency as well as energy conservation projects.
First Solar’s responses are publicly available on the Carbon Disclosure Project website.
