Amount Of Greenhouse Gases Released By Producing Solar Panels

A potent greenhouse gas used to make solar panels is on the rise nitrogen trifluoride emissions in the united states while very low compared to carbon dioxide could be an easy target in the.

Amount of greenhouse gases released by producing solar panels.

Voluntary reporting of greenhouse gases u s. Fabricating the panels requires caustic chemicals such as sodium hydroxide and hydrofluoric acid and the process uses water as well as electricity the production of which emits greenhouse gases. In the united states most of the emissions of human caused anthropogenic greenhouse gases ghg come primarily from burning fossil fuels coal hydrocarbon gas liquids natural gas and petroleum for energy use economic growth with short term fluctuations in growth rate and weather patterns that affect heating and cooling needs are the main factors that drive the amount of energy consumed. The wind energy produced in denmark for example provides about 10 percent of the country s total energy needs.

Make a solar panel by the amount of carbon generated. Using solar energy can have a positive indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. Making solar or photovoltaic cells requires potentially toxic heavy metals such as lead mercury and cadmium. The research published in nature energy measures the full lifecycle greenhouse gas emissions of a range of sources of electricity out to 2050.

Prather an atmospheric chemist at the university of california irvine says that this study provides much needed hard figures and detailed analysis but cautions that it examines only. Forests storing carbon for one year forests are defined herein as managed forests that have been classified as forests for over 20 years i e excluding forests converted to from other land use types. Department of energy energy information administration 16 pp 111k about pdf acres of u s. A typical solar panel must operate for at most four months for the greenhouse gas savings to balance out its fabrication emissions the researchers concluded.

Fortunately the use of alternative energy sources such as solar wind geothermal and hydro energy is gaining increased support worldwide. It even produces greenhouse gases such as carbon dioxide that contribute to global. These methods of energy production emit no greenhouse gases once they are up and running.
