Renewable Energy Sources In Italy – ZeroEmission.tv

Hydro PowerSolar PowerBioenergyWindGeothermalHydropower comprises 41% of all the renewable energy sources in Italy. So far it’s the largest renewable source contributor. Italy has well spread hydroelectric plants in the north where the country has many rivers and mountains. Until in the 1950s, most of its power came from hydroelectric and most of its current power plants have been in existence since the beginning of the 20th century. As at 2010, the country had a total of 2729 plants producing a total of 50582 GWh. Available statistics indicate that Italy’s exploitable hydropower potential is 47TWh with 45TWh already exploited. Therefore it means over 95% potential has already been reached making, therefore, no more room for growth for this source.

Electricity Transmission and Distribution Greenhouse Gas

Sulfur hexafluoride is a commonly used insulator in electricity transmission and distribution equipment. Because of its high global warming potential (GWP), CARB adopted the Regulation for Reducing Sulfur Hexafluoride Emissions from Gas Insulated Switchgear in 2010. As new technologies using lower or zero GWP insulators emerge, CARB staff are proposing to amend the current regulation to further reduce greenhouse gas emissions and to increase flexibility in complying with the standards.

gaz sf6 gas as insulating and arc-quenching medium

Sep 20, 2011 · Sulphur hexafluoride gas (sf6 gas) is employed as insulation in all parts of the installation, and in the circuit-breaker also for arc-quenching. sf6 gas is an electronegative gas, its dielectric strength at atmospheric pressure is approximately three times that of air. It is incombustible, non-toxic, odourless, chemically inert with arc-quenching properties 3 to 4 times better than air at the same pressure.

Why the EU should ban Sulfr hexafluoride - Energy Post

What Is Sulfr hexafluoride? and How Is It used?Is sf6 gas 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?ConclusionSulfr hexafluoride 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 Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry Sulfr hexafluorideis 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.
