Fossil Fuels Are Here To Stay -- August 31, 2020

Re-posting as a stand-alone post:

Best Monday morning article to read, and lo and behold, it's also over at Oilprice. This link and excerpts will be posted as a stand-alone post. The oilprice article links to the most recent IEA report, titled Key World Energy Statistics, 2020. Bottom line: the headline over at Oilprice says it all. Archived.

Some excerpts:

Let’s take a look at consumption, for example. Crude oil accounted for 48.2 percent of final energy consumption globally in 1973. Forty-five years and huge renewable energy advancements later, crude oil’s share in total final energy consumption had fallen by a meager 8.6 percentage points to 40.8 percent.

This is not a lot, even if we acknowledge that the drive to cut emissions started a lot later than the early 70s, so renewables have had less than 45 years to stake their claim as an alternative to fossil fuels. Speaking of which, coal’s share in the mix only fell by 3.6 percentage points in the 45-year period, to 10 percent of the total in 2018.

And this:

Meanwhile, the share of electricity in this mix, thanks to renewables, went up from 9.4 percent to 19.3 percent, which is certainly impressive growth, especially given the abovementioned unequal start. But is it enough?

Let’s look at the total energy supply. In 1973, crude oil accounted for 46.2 percent of the global energy supply. Gas accounted for 16 percent, and coal accounted for 24.5 percent. A category dubbed “Other” (excluding hydro, biofuels and biomass, and nuclear) accounted for 0.1 percent.

Fast forward 45 years, and we have crude oil accounting for 31.6 percent of the total energy supply, gas accounting for 22.8 percent, and coal, somewhat surprisingly, rising to 26.9 percent. Meanwhile, the “Other” category has risen to 2 percent of the total. But so has total energy supply, and not by a small percentage, either. Between 1973 and 2018, global energy supply rose from 6,089 million tons of oil equivalent to more than 14,000 million tons of oil equivalent as the world’s population grew and became more affluent, driving energy demand up.

It is hardly a surprise, then, that emissions have been rising, although the distribution of “responsibility” among the three fossil fuels has changed. Back in 1973, oil was the biggest emitter, accounting for 49.9 percent of the total, with gas accounting for 14.4 percent, and coal for 35.7 percent. In 2018, probably thanks to energy efficiency and the rising share of gas in electricity generation, among other things, the share of oil in total emissions fell to 43.1 percent. Meanwhile, however, coal’s share rose 44 percent, and the share of gas went up to 21.1 percent. What this suggests is what we already know: fossil fuels are cheap, which is why they are often preferred not just in regions that cannot afford to invest in wind and solar but in the world’s largest renewables investor, China, along with most other countries. And while solar and wind are getting cheaper, their reliability remains a problem, which has only recently begun to receive the attention it deserves in the form of a focus on not just generation capacity but also on storage.

Considering the source, a pretty good article. But note that the ultimate source if the IEA (sort of the WHO of the energy world).
