This article is based on a newly published report from the Energy Information Administration (EIA) of the U.S. Department of Energy that projects the continuing demands for energy on Spaceship Earth and the relative growth of renewable and non-renewable sources. Here is an extract from the article:
The contradictory and troubling nature of the energy landscape is on clear display in the 2016 edition of the International Energy Outlook, the annual assessment of global trends released by the EIA this May. The good news about renewables gets prominent attention in the report, which includes projections of global energy use through 2040. “Renewables are the world’s fastest-growing energy source over the projection period,” it concludes. Wind and solar are expected to demonstrate particular vigor in the years to come, their growth outpacing every other form of energy. But because renewables start from such a small base — representing just 12% of all energy used in 2012 — they will continue to be overshadowed in the decades ahead, explosive growth or not. In 2040, according to the report’s projections, fossil fuels will still have a grip on a staggering 78% of the world energy market, and — if you don’t mind getting thoroughly depressed — oil, coal, and natural gas will each still command larger shares of the market than all renewables combined.
Keep in mind that total energy consumption is expected to be much greater in 2040 than at present. At that time, humanity will be using an estimated 815 quadrillion BTUs (compared to approximately 600 quadrillion today). In other words, though fossil fuels will lose some of their market share to renewables, they will still experience striking growth in absolute terms. Oil consumption, for example, is expected to increase by 34% from 90 million to 121 million barrels per day by 2040. Despite all the negative publicity it’s been getting lately, coal, too, should experience substantial growth, rising from 153 to 180 quadrillion BTUs in “delivered energy” over this period. And natural gas will be the fossil-fuel champ, with global demand for it jumping by 70%. Put it all together and the consumption of fossil fuels is projected to increase by 177 quadrillion BTUs, or 38%, over the period the report surveys.
Anyone with even the most rudimentary knowledge of climate science has to shudder at such projections. After all, emissions from the combustion of fossil fuels account for approximately three-quarters of the greenhouse gases humans are putting into the atmosphere. An increase in their consumption of such magnitude will have a corresponding impact on the greenhouse effect that is accelerating the rise in global temperatures.
