Renewable Energy Isn’t Replacing Fossil Fuel Energy

Editor’s note: It is true that wind and heat from the sun are renewable but the devices used to capture that energy are not. Creating such devices only adds on to a non-existing carbon budget. Richard Heinberg, the author of the following article, is an advocate for “renewable” energy as a part of the “transition” to a post carbon civilization. However, the following article demonstrates that the so-called transition is not happening in real life. In reality, civilization and a “post-carbon” future is an oxymoron. Civilization cannot survive in a post-carbon future. It is highly unlikely that humanity will willingly transition out of civilization, so it must be brought down “by any means possible”. The best way to accomplish that is through organizing. The sooner it is brought down, the better for the planet.

Despite all the renewable energy investments and installations, actual global greenhouse gas emissions keep increasing. That’s largely due to economic growth: While renewable energy supplies have expanded in recent years, world energy usage has ballooned even more—with the difference being supplied by fossil fuels. The more the world economy grows, the harder it is for additions of renewable energy to turn the tide by actually replacing energy from fossil fuels, rather than just adding to it.

The notion of voluntarily reining in economic growth in order to minimize climate change and make it easier to replace fossil fuels is political anathema not just in the rich countries, whose people have gotten used to consuming at extraordinarily high rates, but even more so in poorer countries, which have been promised the opportunity to “develop.”

After all, it is the rich countries that have been responsible for the great majority of past emissions (which are driving climate change presently); indeed, these countries got rich largely by the industrial activity of which carbon emissions were a byproduct. Now it is the world’s poorest nations that are experiencing the brunt of the impacts of climate change caused by the world’s richest. It’s neither sustainable nor just to perpetuate the exploitation of land, resources, and labor in the less industrialized countries, as well as historically exploited communities in the rich countries, to maintain both the lifestyles and expectations of further growth of the wealthy minority.

From the perspective of people in less-industrialized nations, it’s natural to want to consume more, which only seems fair. But that translates to more global economic growth, and a harder time replacing fossil fuels with renewables globally. China is the exemplar of this conundrum: Over the past three decades, the world’s most populous nation lifted hundreds of millions of its people out of poverty, but in the process became the world’s biggest producer and consumer of coal.

The Materials Dilemma

Also posing an enormous difficulty for a societal switch from fossil fuels to renewable energy sources is our increasing need for minerals and metals. The World Bank, the IEA, the IMF, and McKinsey and Company have all issued reports in the last couple of years warning of this growing problem. Vast quantities of minerals and metals will be required not just for making solar panels and wind turbines, but also for batteries, electric vehicles, and new industrial equipment that runs on electricity rather than carbon-based fuels.

Some of these materials are already showing signs of increasing scarcity: According to the World Economic Forum, the average cost of producing copper has risen by over 300 percent in recent years, while copper ore grade has dropped by 30 percent.

Optimistic assessments of the materials challenge suggest there are enough global reserves for a one-time build-out of all the new devices and infrastructure needed (assuming some substitutions, with, for example, lithium for batteries eventually being replaced by more abundant elements like iron). But what is society to do as that first generation of devices and infrastructure ages and requires replacement?

Circular Economy: A Mirage?

Hence the rather sudden and widespread interest in the creation of a circular economy in which everything is recycled endlessly. Unfortunately, as economist Nicholas Georgescu-Roegen discovered in his pioneering work on entropy, recycling is always incomplete and always costs energy. Materials typically degrade during each cycle of use, and some material is wasted in the recycling process.

A French preliminary analysis of the energy transition that assumed maximum possible recycling found that a materials supply crisis could be delayed by up to three centuries. But will the circular economy (itself an enormous undertaking and a distant goal) arrive in time to buy industrial civilization those extra 300 years? Or will we run out of critical materials in just the next few decades in our frantic effort to build as many renewable energy devices as we can in as short a time as possible?

The latter outcome seems more likely if pessimistic resource estimates turn out to be accurate. Simon Michaux of the Finnish Geological Survey finds that “[g]lobal reserves are not large enough to supply enough metals to build the renewable non-fossil fuels industrial system … Mineral deposit discovery has been declining for many metals. The grade of processed ore for many of the industrial metals has been decreasing over time, resulting in declining mineral processing yield. This has the implication of the increase in mining energy consumption per unit of metal.”

Steel prices are already trending higher, and lithium supplies may prove to be a bottleneck to rapidly increasing battery production. Even sand is getting scarce: Only certain grades of the stuff are useful in making concrete (which anchors wind turbines) or silicon (which is essential for solar panels). More sand is consumed yearly than any other material besides water, and some climate scientists have identified it as a key sustainability challenge this century. Predictably, as deposits are depleted, sand is becoming more of a geopolitical flashpoint, with China recently embargoing sand shipments to Taiwan with the intention of crippling Taiwan’s ability to manufacture semiconductor devices such as cell phones.

To Reduce Risk, Reduce Scale

During the fossil fuel era, the global economy depended on ever-increasing rates of extracting and burning coal, oil, and natural gas. The renewables era (if it indeed comes into being) will be founded upon the large-scale extraction of minerals and metals for panels, turbines, batteries, and other infrastructure, which will require periodic replacement.

These two economic eras imply different risks: The fossil fuel regime risked depletion and pollution (notably atmospheric carbon pollution leading to climate change); the renewables regime will likewise risk depletion (from mining minerals and metals) and pollution (from dumping old panels, turbines, and batteries, and from various manufacturing processes), but with diminished vulnerability to climate change. The only way to lessen risk altogether would be to reduce substantially society’s scale of energy and materials usage—but very few policymakers or climate advocacy organizations are exploring that possibility.

Climate Change Hobbles Efforts to Combat Climate Change

As daunting as they are, the financial, political, and material challenges to the energy transition don’t exhaust the list of potential barriers. Climate change itself is also hampering the energy transition—which, of course, is being undertaken to avert climate change.

During the summer of 2022, China experienced its most intense heat wave in six decades. It impacted a wide region, from central Sichuan Province to coastal Jiangsu, with temperatures often topping 40 degrees Celsius, or 104 degrees Fahrenheit, and reaching a record 113 degrees in Chongqing on August 18. At the same time, a drought-induced power crisis forced Contemporary Amperex Technology Co., the world’s top battery maker, to close manufacturing plants in China’s Sichuan province. Supplies of crucial parts to Tesla and Toyota were temporarily cut off.

Meanwhile, a similarly grim story unfolded in Germany, as a record drought reduced the water flow in the Rhine River to levels that crippled European trade, halting shipments of diesel and coal, and threatening the operations of both hydroelectric and nuclear power plants.

A study published in February 2022 in the journal Water found that droughts (which are becoming more frequent and severe with climate change) could create challenges for U.S. hydropower in Montana, Nevada, Texas, Arizona, California, Arkansas, and Oklahoma.

Meanwhile, French nuclear plants that rely on the Rhône River for cooling water have had to shut down repeatedly. If reactors expel water downstream that’s too hot, aquatic life is wiped out as a result. So, during the sweltering 2022 summer, Électricité de France (EDF) powered down reactors not only along the Rhône but also on a second major river in the south, the Garonne. Altogether, France’s nuclear power output has been cut by nearly 50 percent during the summer of 2022. Similar drought- and heat-related shutdowns happened in 2018 and 2019.

Heavy rain and flooding can also pose risks for both hydro and nuclear power—which together currently provide roughly four times as much low-carbon electricity globally as wind and solar combined. In March 2019, severe flooding in southern and western Africa, following Cyclone Idai, damaged two major hydro plants in Malawi, cutting off power to parts of the country for several days.

Wind turbines and solar panels also rely on the weather and are therefore also vulnerable to extremes. Cold, cloudy days with virtually no wind spell trouble for regions heavily reliant on renewable energy. Freak storms can damage solar panels, and high temperatures reduce panels’ efficiency. Hurricanes and storm surges can cripple offshore wind farms.

The transition from fossil fuel to renewables faces an uphill battle. Still, this switch is an essential stopgap strategy to keep electricity grids up and running, at least on a minimal scale, as civilization inevitably turns away from a depleting store of oil and gas. The world has become so dependent on grid power for communications, finance, and the preservation of technical, scientific, and cultural knowledge that, if the grids were to go down permanently and soon, it is likely that billions of people would die, and the survivors would be culturally destitute. In essence, we need renewables for a controlled soft landing. But the harsh reality is that, for now, and in the foreseeable future, the energy transition is not going well and has poor overall prospects.

We need a realistic plan for energy descent, instead of foolish dreams of eternal consumer abundance by means other than fossil fuels. Currently, politically rooted insistence on continued economic growth is discouraging truth-telling and serious planning for how to live well with less.

Richard Heinberg is Senior Fellow of Post Carbon Institute, and is regarded as one of the world’s foremost advocates for a shift away from our current reliance on fossil fuels. He is the author of fourteen books, including some of the seminal works on society’s current energy and environmental sustainability crisis.
