Renewable electricity generation in the UK reached a record 99.3 terawatt hours (TWh) in 2017. This pushed up the proportion of electricity supplied by renewables to 30%, up from 25% in both 2016 and 2015, as the chart below shows. This was a rise of 1.2 percentage points compared to 2016 levels. The remaining two-thirds come from fossil fuels – mostly coal and gas. The headline in The Independent newspaper claims that in the UK more energy came from low-carbon sources than fossil fuels in 2019. We therefore need to transition away from them. This is because the other elements of the energy demand – transport and heating – rely much more heavily on fossil fuels. Why are deserts located along the tropics? Despite the recent resurgence of coal, DECC expects its use in electricity generation to fall sharply over the next 10 years. For example, France gets more than 70% of its electricity from nuclear power. Where do we get our electricity from? As we look at in more detail in this article, the breakdown of sources – coal, oil, gas, nuclear and renewables – is therefore different in the electricity versus the energy mix. How do weather and climate affect river landscapes? How is the UK’s energy mix changing? And here the change in energy mix has been more dramatic. Gas: what share of electricity comes from gas? of November, 2020 at 21:00 GMT. Electricity (sometimes referred to as ‘power’) is only a subset of total energy production, which also includes heating and transport. What is the breakdown of our electricity supply in terms of fossil fuels, renewable energy and nuclear power? But how much of it do we use, and where does it come from? Arguably a more important measure is the low-carbon share of electricity, which reached a record 38% last year. We must take these country-level examples and learn from them. Don’t include personal or financial information like your National Insurance number or credit card details. For coal, oil, gas and bioenergy, lighter shades indicate imports and darker shades domestic supplies. Globally, 36.7% of our electricity was low-carbon in 2019. Last year was a case in point, as record warm temperatures reduced home heating demand. But there is another aspect to consider. This interactive map shows the share of electricity that comes from fossil fuels (coal, oil and gas summed together) across the world. This is the lowest ever share in the modern era. Onshore windfarm, Eaglesham Moor, East Renfrewshire, Scotland. What is the Demographic Transition Model? The River Tees – landforms of erosion and deposition, Case Study – Ganges/Brahmaputra River Basin, Geological time is on a different time to human time, Different rocks create contrasting landforms and landscapes. The site is self-funded and your support is really appreciated. All energy suppliers in the UK, big and small, have an energy mix and the same can be said for most suppliers around the world. Factcheck: What is the carbon footprint of streaming video on Netflix? There are 39 CCGT power stations in the UK. Total and fossil energy use were both down last year, making it hard to gauge the bigger picture. In some countries it is one of – if not, the single – largest source of electricity. Jet stream: Is climate change causing more ‘blocking’ weather events? We see a large difference between the share that comes from low-carbon sources. By Richard AndersonBusiness reporter, BBC News. In other words, the UK will use less energy in 2030 than it did in 1970. Despite large shifts in renewable and coal output, the UK mix is still dominated by fossil-fired generation (light and dark grey areas). As we noted earlier, the relative contribution of fossil fuels and low-carbon electricity has been pretty stagnant for decades. Changing rates of rainforest deforestation. .css-14iz86j-BoldText{font-weight:bold;}The energy we produce underpins pretty much everything we do. Bear in mind, however, that we are talking here about the primary source of the energy we consume - coal, oil and gas are also used to generate electricity (see below). By clicking on a given country you can see how this share has changed over time. This trend accelerated in the first quarter of this year before coming to an abrupt halt after 1 April, when changes to solar subsidies kicked in. From a climate perspective, this transition is positive since gas typically emits less CO2 per unit of energy. Published under a CC license. As highlighted above, the falling prominence of coal in the UK’s primary energy supply is clearly visible in the shrinking width of the black lines. More significant contributions came from wind, with nearly 10%, and bioenergy. Even just 10 years earlier, the share stood at 91%. But the report also reveals a tailing off in the expansion of solar electricity.
