The end, said a reincarnated Cassandra, is nigh. Fossil fuels are available in limited supply. As of December 2019, over 1,200 institutions representing more than $12 trillion have divested from fossil fuels, according to Wikipedia. But even though the use of renewables is expected to grow faster than fossil fuels, the US Energy Information Administration (EIA) says coal, oil and natural gas will still account for 77% of our energy in 2040. [2] These are calculated at a 50% confidence for 1.5 o C and 80% confidence for 2 o C. At the current consumption rate, fossil fuels aren't sustainable energy sources. “The world's energy market worth around 1.5 trillion dollars is still dominated by fossil fuels” (Goldemberg, 2006).The World Energy Outlook (WEO) 2007 claims that energy generated from fossil fuels will remain the major source and is still expected to meet about 84% of energy demand in 2030. Natural gas is likewise expected to peak some time around 2010-2020, and coal around 2020-2030. How Long Will Fossil Fuels Last? Knowledge is Energy. Different fossil fuels are expected to last differing times, for the most accessible (Gas and Oil) we have already passed peak production and will have virtually run out by 2050. How long a substance lasts depends on two key factors: reserves and usage rate. This is particularly true for developing nations such as Nigeria, Malawi and Niger. Oil, natural gas and coal together provide 86% of the world's primary energy. Are Fossil Fuels Bad? For some investors, engagement isn’t enough, they don’t want to support the fossil fuel industry with their capital at all. Although this number is frequently argued upon, it is believed that oil and natural gas will run out in approximately 55 years, while coal will run out in over 100 years. The Downsides of Using Fossil Fuels. After all, she argued, at current rates of production, oil will run out in 53 years, natural gas in 54, and coal in 110. Even without capturing livestock and landfill sources, natural gas is expected to last 400 years at current rates of use. 8. Fossil fuel divestment campaigns have rapidly accelerated since 2017. If we all continue to rely heavily on fossil fuels for our energy supply, climate-change related damages will become very severe long before there is any real pressure on our fossil fuel supply. This means that we have managed to deplete resources that were formed in over 66 million years in less than 200 years. Abundant supplies of fossil fuels will end, bringing down the economic order with it. Most deposits require complex drilling and hydraulic fracturing to reach. By 2040, fossil fuels are still expected to account for 78 percent of global energy use. Natural gas reserves are expected to last about 400 years. ‘Proven reserves’ of fossil fuels refer to fossil fuels that are in the ground and that are known (with a 90% certainty) to be recoverable under current technical and market conditions. “If demand for fossil fuels bounces back in 2021 by half the amount it fell in 2020, and grows at 0.5% a year, it would take 8 years to get back to where the industry started. 7. When Will Fossil Fuels Run Out? The estimates for when global fossil fuel reserves would theoretically run out vary widely based on who you ask, and are affected by new technological advancements, decarbonization efforts, and changing usage rates; however, if humans want to survive the dramatic effects of climate change, the fossil fuels on our planet must never be used up. 1..
