Climate change: Electrical industry'dirty secret' boosts

Sep 14, 2019 · Cheap and non-flammable, sf 6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations. It is widely used across the industry, from large power stations to wind turbines to electrical sub-stations in towns and cities. It prevents electrical accidents and fires.Get price

Why SF₆ emissions from the renewable energy sector should not

Increasing insulating gasGlobal Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...Get price

Energy in New Zealand - Wikipedia

Despite abundant natural resources and a relatively small population, New Zealand is a net importer of energy, in the form of petroleum products. The ratio of non-renewable and renewable energy sources was fairly consistent from 1975 to 2008, with about 70 percent of primary energy supply coming from hydrocarbon fuels. This ratio decreased to about 60 percent in 2018. The proportion of non-renewable energy varies annually, depending on water flows into hydro-electricity lakes and demand for enerGet price
