Wind energy, CO2, climate change and insulating gas in perspective

Sep 25, 2019 · At end-of-life the turbine switchgears are collected and the sulphur hexafluoride gas is reclaimed and reused in new equipment. By comparison wind energy avoids the emission of 255 million tonnes of CO 2 in Europe a year by generating 336TWh of electricity displacing fossil fuels. The sf 6 leakage therefore represents around 0.001% of the emissions avoided thanks to wind energy every year.Get price

Renewable Energy Projects in Switzerland and the EU

Rejection of Nuclear Power in EuropeEnergy Transition After FukushimaThe European Union’s Renewable Energy ProjectIreland is – besides Luxembourg, Liechtenstein, Poland, and Latvia – an example of a European country that never produced nuclear power on its own grounds. Mainly due to the resistance of huge parts of the Irish people Ireland did not step into the construction of nuclear power plants, which were on its government’s agenda in the 1960s and 1970s. Austria’s referendum of 1978 to not produce nuclear power on its national territory is also remarkable. Not only because the referendums’ result was understood as a vote against the chancellor at that time, but also because of the fact, that the nuclear plant “Zwentendorf” was already built. Greece decided to stop the construction of its nuclear plant in 1983, which was decided to be built by the Hellenic Parliament in 1976, due to safety concerns. The Danish parliament decided against the generation of nuclear power on its national ground in 1985. Early experimental plants were installed already in the late 1950s and shut down in 2003.

Why the EU should ban sf 6 - Energy Post

What Is sf 6? and How Is It used?Is gaz sf6 A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of Sulfr hexafluoride Emissions Difficult? Do Better Solutions Exist?Conclusionsf 6 is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all sf 6produced (Powell, 2002: 6). Within the electrical industry gaz sf6is used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.Get price
