This is a huge step forward. However, most pledges are not yet underpinned by near\u2010term policies and measures. Moreover, even if successfully fulfilled, the pledges to date would still leave around 22 billion tonnes of CO2 emissions worldwide in 2050. The continuation of that trend would be consistent with a temperature rise in 2100 of around 2.1 \u00b0C.<\/p><\/blockquote>\n<h2>Energy sources<\/h2>\n<p>The chart below, showing global energy use by source, reflects the scale of the problem. Note that the 2020 fall in global emissions was due to the COVI-19 pandemic and is &#8220;already rebounding strongly as economies recover&#8221; (IEA report). Global consumption of oil and gas has continued to grow despite the introduction of wind and solar. Coal consumption declined since 2014 but was partly replaced by an increase in the rate of gas consumption in 2018-2019. That trend is likely to continue &#8212; as gas produces roughly half the CO<sup>2<\/sup> emissions of coal &#8212; and has resulted in a sharp spike in global gas prices.<br \/>\n<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/i0.wp.com\/www.incrediblecharts.com\/images\/2022\/primary-sub-energy-source.png?resize=525%2C371&#038;ssl=1\" alt=\"Energy Sources\" width=\"525\" height=\"371\" \/><\/p>\n<h3>Wind and solar<\/h3>\n<p>It is unlikely that solar and wind &#8212; with 2020 outputs of 900 TWh and 1,600 TWh respectively &#8212; will ever be able to replace the combined 125,000 TWh of energy generated by coal, oil and gas.<\/p>\n<h3>Hydro-electric<\/h3>\n<p>Hydropower growth is expected to slow. Having enjoyed a surge in the past 20 years, with heavy dam construction in China, new opportunities are mostly limited to Africa and South America.<\/p>\n<p><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/i0.wp.com\/www.incrediblecharts.com\/images\/2022\/renewable-energy-gen.png?resize=525%2C371&#038;ssl=1\" alt=\"Renewable Energy Sources\" width=\"525\" height=\"371\" \/><\/p>\n<h3>Electric vehicles<\/h3>\n<p>Electric vehicles are expected to dent global oil demand over time but oil producers are not having sleepless nights. Bloomberg New Energy research estimates that electric and fuel cell vehicles will <a href=\"https:\/\/about.bnef.com\/electric-vehicle-outlook\/\" target=\"_blank\" rel=\"noopener\">displace 21 million barrels per day in oil demand <\/a>by 2050. Current oil usage is 102 mb\/d (IEA 2021) but is increasing at annual rate of 1 mb\/d (IEA), leaving us with an estimated <strong>net increase<\/strong> in oil consumption of 8 mb\/d by 2050.<\/p>\n<h3>Hydrogen<\/h3>\n<p>Hydrogen is being touted as an alternative to oil and gas but there are two hurdles to overcome. First is the cost of generating hydrogen. There are two alternatives: creating hydrogen from water using electrolysis and separating hydrogen from methane gas (CH<sup>4<\/sup>) using a catalyst. Electrolysis has the advantage of a cheaper feedstock (water) but the most efficient <a href=\"https:\/\/thepatientinvestor.com\/index.php\/why-evaluate-trends\/mega-trends-decarbonization\/hydrogen-fuel-cells-and-electrolyzers\/\">PEM electrolyzers<\/a> require expensive platinum and iridium-coated cathodes and anodes, respectively, for operation at high temperatures. Methane pyrolysis requires natural gas as a feedstock but has the advantage of generating saleable carbon as a by-product. Carbon black is used in manufacturing car tires and industrial rubber, but most feasibilities I have seen assume current prices which are based on a limited supply. Separating methane would generate 2 tons of carbon for every ton of hydrogen, creating an over-supply.<\/p>\n<p>The downfall of both alternatives is that they require vast amounts of energy for the conversion. That brings us back to the question: where are we going to find cheap CO<sup>2<\/sup>-free sources of energy on a vast scale?<\/p>\n<p>The second major hurdle for hydrogen is the cost of manufacturing <a href=\"https:\/\/thepatientinvestor.com\/index.php\/why-evaluate-trends\/mega-trends-decarbonization\/hydrogen-fuel-cells-and-electrolyzers\/\">fuel cells<\/a>. These also require cathodes and anodes coated with platinum group metals to prevent erosion at high temperatures.<\/p>\n<p>Hydrogen generation is not yet economically viable and hopes for future cost reduction are based on as yet undeveloped technology.<\/p>\n<h3>The dark side of solar<\/h3>\n<p>Significant achievements have been made in reducing the cost of solar panels &#8212; but at a cost.<\/p>\n<blockquote><p>Xinjiang has become a major polysilicon production hub in China, as the industry requires extensive amounts of energy, and that makes relatively cheaper electricity and abundant thermal power in Xinjiang appealing. (<a href=\"https:\/\/www.globaltimes.cn\/page\/202105\/1223611.shtml\">Global Times<\/a>)<\/p><\/blockquote>\n<p>Xinjiang has also been the focus of reports on the use of Uighur forced labor. Savings achieved through cheap coal-fired power and slave labor are not real savings but come at major costs in terms of CO<sup>2<\/sup> emissions and human suffering.<\/p>\n<h2>Nuclear<\/h2>\n<p>The only viable alternative to carbon fuels, especially coal, is nuclear. Initial  construction costs may appear high but most estimates are based on the few  large-scale nuclear power stations built as stand-alone projects over the past four decades. Significant savings are achievable by building <a href=\"https:\/\/thepatientinvestor.com\/index.php\/why-evaluate-trends\/mega-trends-decarbonization\/nuclear-power\/\">small modular reactors<\/a> (SMRs) in a factory setting, with robotic welders, and transporting them to site. Economies of scale would play a huge part in achieving affordable CO<sup>2<\/sup>-free nuclear energy around the globe.<\/p>\n<p>Nuclear energy is far safer than carbon fuel alternatives and comparable to renewable energy. Especially when one considers that the safety record below is based on old, inefficient designs &#8212; Chernobyl  and Fukushima &#8212; that are far more prone to accidents than modern SMRs.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/i0.wp.com\/www.incrediblecharts.com\/images\/2022\/5-Bar-chart-%E2%80%93-What-is-the-safest-form-of-energy.png?w=525&#038;ssl=1\" alt=\"Safety\" \/><\/p>\n<p>Nuclear delivers the highest return when measured in terms of Energy Returned on Energy Invested (EROEI or EROI)<sup>1<\/sup>.

Energy sources must exceed the economic threshold of about 7 (blue line) in order to yield the surplus energy required to support a modern society.
