Traditional biomass – which are. Oil and gas combined are forecast to still supply over 50 percent of the world’s energy needs by 2045, with oil at around 27 percent and gas at 25 percent. The impacts vary by fuel. Despite producing more and more energy from renewables each year, the global energy mix is still dominated by coal, oil, and gas. But in recent years it has. This interactive map shows the share of primary energy that comes from coal across the world. How quickly is solar production changing? We have three different energy mixes: only fossil fuels; only renewable or nuclear energy; and a mix of both. This report briefly explains key aspects of global natural gas markets, including supply and demand, and major U.S. developments. Direct vs. substituted primary energy: what are the multiple ways of energy accounting? Energy sources are measured in different physical units: liquid fuels in barrels … The global energy landscape is changing, and fast. Challenges For Global Energy Mix February 22nd, 2021, 5:21 AM GMT+0000 BNEF Global Head of Commodities Ashish Sethia discusses the challenges for global energy … But If we look back a couple of centuries ago, our energy mixes where relatively homogeneous. Please consult our full legal disclaimer. Oil is the world’s largest energy source today. But it’s also the most polluting energy source: both in terms of the amount of CO2 it produces per unit of energy, but also the amount of local air pollution it creates. Do we have examples of countries who are already paving the way towards a fossil-free energy mix? We can calculate this by dividing our 100 TWh demand by 0.38. For instance, when oil is extracted from the ground it must be refined into gasoline, so that it can be used in a car, and transported over long distances to gas stations where it can be use… Globally, the cumulative share of coal, oil and gas in the energy mix in 2018 was close to 85%, with hydro (6.8%), other renewables (4%) and nuclear (4.4%) trailing far behind. Today when we think about energy mixes we think about a diverse range of sources – coal, oil, gas, nuclear, hydropower, solar, wind, biofuels. This is shown in the figure. On this basis, McKinsey’s Global Energy Insights team has put together a description of the global energy landscape to 2050. How do our long-term energy transitions look when we consider two additional elements: the work of humans and animals? In the chart here we see primary energy consumption in absolute terms for each source. We look at this question in a related post here. How is hydropower generation changing in absolute terms? By clicking on any country on the map you see the change over time in this country. In 2019, the share of renewable energy sources (RES, including hydropower) within the global power generation mix rose by 1.1 percentage point to nearly 27% of the power mix, following the rising trend it started in the 2000’s. So at Our World in Data we try to maintain consistency by converting all energy data to watt-hours. Energy Transitions: Global and National Perspectives, Annex III: Technology-specific cost and performance parameters. It allows us to compare energy mixes across the world; track whether we are making progress on decarbonizing our energy systems; and plan and manage demands for natural resources. Fossil fuels: what share of energy comes from fossil fuels? Natural gas: increase to 25% by 2040 The share of renewables in the global energy mix is also expected to rise. Natural gas has, for decades, lagged behind coal and oil as an energy source. But some countries – often some of the world’s richest countries who have high carbon footprints – show us that significant progress on decarbonizing our energy systems is possible. Gas: what share of energy comes from gas? By ticking the ‘Relative’ box in the bottom left corner you can switch to see each source’s share of the total. This interactive map shows the share of primary energy that comes from gas across the world. Oil: what share of energy comes from oil? What immediately stands out is that there is a reasonably strong East-West divide: most Western economies get a larger share of energy from low-carbon sources, and those in East get less. BP Statistical Review of World Energy, Definitions and Exploratory Notes (2020). Ramping up electricity to over half of the global energy mix (up from one-fifth currently) in combination with renewables would reduce the use of fossil fuels, responsible for most greenhouse-gas emissions. How much of our energy currently comes from low-carbon sources? How close are we to getting rid of fossil fuels? Wind: what share of energy comes from wind? Figure 13. Contribution of Working Group III to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change [Edenhofer, O., R. Pichs-Madruga, Y. Sokona, E. Farahani, S. Kadner, K. Seyboth, A. Adler, I. Baum, S. Brunner, P. Eickemeier, B. Kriemann, J. Savolainen, S. Schlömer, C. von Stechow, T. Zwickel and J.C. Minx (eds.)]. But our rate of progress since the 1990s has been less impressive. Using the “change country” toggle you can switch to see the breakdown for other countries. Energy production – mainly the burning of fossil fuels – accounts for around three-quarters of global greenhouse gas emissions. These figures don’t include energy produced from traditional biomass. You see this breakdown in the interactive chart below. And we assume the efficiency of a fossil fuel plant is 38%. This is even clearer when we focus in on global electricity production: nuclear declined by almost as much as renewables gained. In the energy domain, there are many different units thrown around – joules, exajoules, million tonnes of oil equivalents, barrel equivalents, British thermal units, terawatt-hours, to name a few. The emissions from these sources are not necessarily zero – the mining of materials, production, maintenance and decommissioning of these technologies may produce some carbon, but per unit of  energy this is  very small relative to fossil fuels.Schlömer S., T. Bruckner, L. Fulton, E. Hertwich, A. McKinnon, D. Perczyk, J. Roy, R. Schaeffer, R. Sims, P. Smith, and R. Wiser, 2014: Annex III: Technology-specific cost and performance parameters. 3. They account for more than 80% of energy consumption. We calculate the equivalent amount of fossil fuels that would be required to produce the amount of electricity we get from non-fossil based sources. But there are large differences in the role of nuclear – some countries rely heavily on it for energy production; others produce no energy at all from it. These difficulties result in different approaches for ‘energy accounting’ and present a different picture of the energy mix. Within the EU, 75.9% came from fossil fuels, 14.1% from nuclear power, 7% from biofuels, 2.9 from renewable energy resources. ‘Renewables’ typically includes hydropower, solar, wind, geothermal, biomass and wave and tidal energy. This interactive map shows the share of primary energy that comes from wind (both onshore and offshore) across the world. And are we making progress in shifting towards a low-carbon energy system? In the chart we see the share of global energy that comes from fossil fuels, renewables and nuclear. At Our World in Data we get most of our energy data from BP; each year it publishes its Statistical Review of World Energy report. Assuming current Paris Agreement pledges are maintained beyond 2030, the share of fossil fuels in the global energy mix … What are often referred to as ‘modern renewables’ – solar and wind – were only added much later, in the 1980s. Our assessment is that global energy demand is set to drop by 5% in 2020, energy-related CO 2 emissions by 7%, and energy investment by 18%. This has major implications for the global climate, as well as for human health. Explore all the metrics – energy production, electricity consumption, and breakdown of fossil fuels, renewable and nuclear energy. Part of this slow progress is due to the fact that much of the gains made in renewables has been offset by a decline in nuclear energy. How has this changed over time? 11.4% came from renewables; and 4.3% came from nuclear. Think of this as inputs into an energy system: coal, oil or gas before we burn them; or solar or wind energy before we convert them to electricity. But what seems like a simple exercise – adding up the produced energy from all the different sources – is in fact not straightforward at all. This earlier data is sourced from Vaclav Smil’s work Energy Transitions: Global and National Perspectives.1 Data from 1965 onwards comes from the latest release of BP’s Statistical Review of World Energy.2. Since the Industrial Revolution, the energy mix of most countries across the world has become dominated by fossil fuels. Using the “change country” button in the bottom-left of each chart, you can also see this for different countries. Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). Most fossil fuel plants run with an efficiency of around 33% to 40%.13 The remaining 60% to 67% of energy is wasted as heat. See the breakdown of the energy mix. Renewables contributed 9×10^15 BTU (9.5×1015 kJ) and nuclear power 8×10^15 BTU (8.4×1015 kJ). Finland, and Brazil also had a high share – more than 40%. It’s moving in the right direction, but far too slowly – probably much more slowly than many expect. As a result, renewables increased its share in the energy mix from 4.5% in 2018 to 5%. Following this scenario, fossil fuel usage would drop significantly, but it would require a dramatic increase of use of renewable resources, particularly in Asia.[12]. The World’s energy supply sources for the years 2013 and 1973 are shown in the Figures 2.3 and 2.3a below. When we are asking how much energy is consumed or what the breakdown of the sources of energy is we are asking about primary energy. Ongoing changes in the fossil fuel markets, renewable energy market and electricity market will be examined. Nuclear power generation should remain a part of the global energy mix despite challenges related to tightening regulations, safety concerns, ageing asset bases, and increasingly volatile energy markets, S&P Global Ratings says in two reports published today. Low-carbon sources are the sum of nuclear energy and renewables – which includes hydropower, wind, solar, bioenergy, geothermal and wave and tidal.6. What does our energy mix look like today? We have a rough categorization of countries that are above and below the global average. This article about energy, its collection, its distribution, or its uses is a stub. North America had the highest consumption per resident, with Russia in second, and Europe and the Middle East following. Coal has been a critical energy sources, and mainstay in global energy production for centuries. Pipelines will play a vital role in transporting hydrogen in the new carbon free global economy. And in the past years it has been growing too quickly for renewables and nuclear to keep up. Global primary energy: how has the mix changed over centuries? How big is this challenge? Does our track record give us reason to be optimistic that we can quickly decarbonize? Combined, they are the largest source of global emissions of carbon dioxide (CO2). How does it convert from direct primary energy – that we can measure – into the substitution breakdown? Explore the data. Energy consumption worldwide rose 2.9%, which is the largest increase since 2010. We’ve seen the breakdown of the energy mix today. This can vary from plant-to-plant, and by fuel type. How much of our energy comes from fossil fuels, renewables and nuclear energy? the Global Energy Mix The role of natural gas in the U.S. economy has been a major part of the energy policy debate in the 114th Congress. I’ve also summarised this breakdown in the table – noting each source’s’ share at various points in time since the 1970s. We continue to produce more energy from fossil fuels – particularly oil and gas – each year.12. Hydropower and nuclear account for most of our low-carbon energy: combined they account for 10.7%. Brazil, as we mentioned earlier, achieves a much higher share – 46% in 2019. This divide may be in part, due to differences in income: many richer countries with a long history of fossil fuel-rich energy systems have already shifted away from them.8. Fossil fuels are the sum of coal, oil and gas. This means traditional biomass burning – a dominant source of energy at lower incomes are not included. But how rapidly and to what extent is still up for debate. Imagine we have a country that needs 100 terawatt-hours (TWh) of energy. Global coal production increased by 1.5%, led by increases in China and Indonesia. But we know that some power plants have a slightly lower or higher efficiency and it can change over time. Explore the breakdown of the electricity mix and how this is changing. Contribution of Working Group III to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change [Edenhofer, O., R. Pichs-Madruga, Y. Sokona, E. Farahani, S. Kadner, K. Seyboth, A. Adler, I. Baum, S. Brunner, P. Eickemeier, B. Kriemann, J. Savolainen, S. Schlömer, C. von Stechow, T. Zwickel and J.C. Minx (eds.)]. 2018 saw the largest increase in worldwide energy consumption since 2010, with 27.2% of that energy coming from coal. This interactive map shows the share of primary energy that comes from renewables (the sum of all renewable energy technologies) across the world. Amongst the largest emerging economies, South Africa produced only 5% from low-carbon sources; India got 9%; and China, 15%. This breakdown of primary energy is based on the ‘substitution method’ which corrects for the inefficiencies in energy production from fossil fuels, and is a better representation of low-carbon energy’s share of ‘useful energy’. Explore in more detail in our work on Renewable Energy. But do some countries do much better than this? [8], Many countries, such as Pakistan[9] and Malaysia[10] have begun developing options for more sustainable energy practices. The share of energy we get from individual renewable technologies – solar, or wind, for example – are given in the sections below. Solar energy is often referred to as a ‘modern renewable’ – a couple of decades ago it made only a tiny contribution to global energy supply. What’s important is to understand why there are two different methods and how they affect our perspective on the energy mix. Are we making progress in decarbonization over time? The aim here is to fill that gap. I find it helpful to think of the distinction as: A question many want the answer to is, how much of our energy comes from low-carbon sources? Get an overview of energy for any country on a single page. According to the International Energy Agency (IEA) 13.6% of world primary energy was used by the European Union (EU). This interactive map shows the share of primary energy that comes from solar technologies across the world. That is what ultimately determines the amount of CO2 we emit, and the rate at which it accumulates in the atmosphere. Explore in more detail in our work on Renewable Energy. Many of the world’s oil-producing countries – Saudi Arabia, Oman, and Kuwait – got less than 1% from low-carbon sources. So, instead of assuming fossil fuels have the same efficiency as renewables/nuclear, we do the opposite: we assume renewables/nuclear are as inefficient as fossil fuels. ", "Life cycle sustainability assessment of electricity generation in Pakistan: Policy regime for a sustainable energy mix", "Renewable energy for continuous energy sustainability in Malaysia", "Sustainable energy options for Pakistan", "The World's Projected Energy Mix, 2018-2040", List of top international rankings by country, https://en.wikipedia.org/w/index.php?title=Energy_mix&oldid=983035970, Creative Commons Attribution-ShareAlike License, This page was last edited on 11 October 2020, at 21:22. As we look at in more detail below – “How much of global energy comes from low-carbon sources?” – the global energy mix is still dominated by fossil fuels. Meanwhile, low-carbon fuels and technologies, in particular, solar PV and wind, reached their highest ever annual share of the global energy mix, increasing it by more than one percentage point to over 20%. The remaining quarter comes from industrial processes (mainly cement production), agriculture, land use change and waste. This would be the amount of primary energy that would be required from fossil fuels to produce the same amount of electricity as wind. [6], In 2018, the global primary energy use was 33.6% oil, 27.2% coal, 23.9% natural gas, 6.8% hydro, 4.4% nuclear, and 4% other renewables, such as wind, thermal, bioenergies, solar, and waste.
