Kurt Cobb, author, speaker, and columnist focusing on energy and the environment, explains why we shouldn’t expect a speedy transition from fossil fuels to renewable energy sources. At the end of the article, an informed reader affirms Cobb’s position: “As someone who has worked on large energy projects for many years I am very aware that they take a long time.”

…recent news items remind us that energy transitions take time, a lot of time–far too much time to be shrunk down into a television special, a few talking points, or the next big energy idea.
…energy maven Vaclav Smil wrote a piece for Politico discussing the difficulties in making an energy transition from one kind of dominant fuel to another. Despite all the hype from technology gurus touting an imminent takeover by solar, wind and biofuels, historically such transitions have taken decades. The technologies for energy production are simply not analogous to the technologies behind advances in computer chips.
Inventor and futurist Ray Kurweil’s prediction that solar energy will become practically the only source of power in just 16 years illustrates the failure of technology-oriented minds to understand the constraints on energy transitions. He predicts a doubling every two years. That will sound familiar to those in the computer industry where a doubling in the computing power of microchips has occurred about every 18 months.
Energy transitions, however, move slowly–egregiously slowly–compared to advances in such fields as biotechnology and integrated circuits.
On a percentage basis renewables are growing rapidly, but from a very small base. Smil comments:
Electricity generation by new renewables has been growing fastest, but it is far from taking over: at 7 percent in 2014 it was still only about a third of all electricity generated by the aging nuclear stations. And because electricity is only a part of the overall energy supply, the contribution of new renewables (wind and solar) to the country’s total primary energy consumption (including all industrial and transportation fuels) remains very modest: it rose from just 0.1 percent in the year 2000 to 1 percent in 2010 and to 2.2 percent in 2014.
What those who map the rapid increase in computer power onto our current energy transition miss is the infrastructure problem. Consumers and businesses seem to have little concern over junking computers that are only a few years old in favor of the newest models. The turnover in the computer infrastructure is quite rapid.
Not so with energy infrastructure. Power plants are made to last decades. And, they are often upgraded rather than replaced. Currently, fossil fuels produce the bulk of the world’s electricity, some 67 percent in 2012, according to the latest figures available from the U.S. Energy Information Administration. Nuclear power plants produce almost 11 percent. Hydroelectric produces almost 17 percent. All other renewable electricity production accounts for just under 5 percent. Very little of the existing electricity generation infrastructure is coming down soon.
What this means is that far from replacing existing fossil fuel generating plants, renewables are simply going to add to total electricity generation as demand grows. That’s a good thing. But renewable energy expansion as it is currently structured is going to do little to reduce greenhouse gases. In fact, in the United States the decline in carbon dioxide emissions from the peak in 2005 to a level 12.8 percent lower in 2012 was due almost entirely to the substitution of natural gas-fired electricity generation for coal-fired generation. But emissions resumed their upward march in 2013 and 2014 as the most polluting of the coal-fired plants had already shut down.
As for liquid fuels, decades of trying have only resulted in marginal inroads from non-petroleum substitutes. Petroleum-based fuels still account for 95 percent of all transportation fuel in the United States as of 2014. World numbers are hard to come by. The World Petroleum Council states that the global share for petroleum in transportation fuels is 80 percent, but cites no source.
So what does all this imply? Is there anything we can do to speed up the transition?
Of course, we could all sit back and simply hope for technical breakthroughs that will make it irresistible–in other words, highly profitable–to adopt low-carbon energy technologies on a massive scale quickly. But, history recommends against this passive course.
While some decry subsidies given to wind, solar and biomass technologies, there is an almost immutable law of economics which justifies these, to wit: If you subsidize something, you will get more of it. And, that’s what policymakers behind the subsidies want. What the critics of such subsidies fail to note is that governments worldwide currently pay out $550 billion in subsidies annually for the production of oil, coal, and natural gas, more than four times the subsidies for renewables including wind, solar and biomass–which again proves that when you subsidize something, you get more of it. And, we have gotten a lot of fossil fuel production.
Why not just take that $550 billion and devote it to research on and production and deployment of renewable energy? That would be okay. But a much better use of that money would be spending it on known technologies that drastically REDUCE our consumption of energy. If, as Vaclav Smil contends, we are in for a long, slow slog on the path to a renewable energy economy, then the course with the least risk and probably the greatest return would be to reduce our energy use.
We have the technology to reduce building heating and cooling energy use by 80 to 90 percent. It’s called passive house technology though it is now also being applied to apartment, commercial and industrial buildings. The cost for this in new buildings is about 15 percent more and typically lower. The energy savings over the life of building far outweigh the initial cost. We still need to figure out how to do cost-effective retrofits for similar deep energy reductions in existing buildings. But there are many smaller cost-effective steps currently available to homeowners and businesses. Some of these are already being subsidized, and subsidizing them more would be a good idea.
When it comes to transportation, the advent of ridesharing and car-sharing is rapidly changing the public’s view about automobiles. No longer do people need to own a car so much as have access to it. Combine this with an expansion of hybrid vehicles and efficiencies can quickly build in the transportation sector.
There is much more that we can do and that we know how to do to reduce energy use, especially energy produced by fossil fuels. But a corollary to the above mentioned “law” of economics concerning subsidies is one concerning taxes, namely, if you want less of something, tax it. A high and rising carbon tax would go a long way toward speeding the energy transition. It would incentivize households, businesses, nonprofit organizations and government, that is, everybody, to reduce fossil fuel use and to choose renewables instead.
Even with these efforts our current and increasingly urgent energy transition would still take a long time. But we would have more assurance of a positive outcome with regard to climate change if we choose now to start on a course toward dramatic reductions in energy use. And, coincidentally, this would make it much easier for renewable energy to replace fossil fuels since we would ultimately need far less energy production to replace them. The renewable energy economy could then arrive sooner and with far less direct investment than previously imagined.

Excellent article — thanks for sharing, especially your comments about the slowness with which primary energy sources change. So many articles and discussions assume that all types of energy are equivalent. With regard to transportation it is taken for granted that we can make a quick and seamless transition from liquid fuels to electricity. The technology does seem to be increasingly viable but it is all going to take a long time — time that we don’t have. As the 2005 Hirsch report stated,
While significant improvements in fuel efficiency are possible in automobiles and light trucks, any affordable approach to upgrading will be inherently time-consuming, requiring more than a decade to achieve significant overall fuel efficiency improvement.
As someone who has worked on large energy projects for many years I am very aware that they take a long time. Moreover a transition to electrically-powered vehicles will require a huge investment in new infrastructure, and much of that investment will require fossil fuels for its manufacture and installation.
As to reducing our energy consumption, today I was talking to a “snowbird” friend. She and her husband have homes in the north (summer) and Florida (winter). She is very aware of energy and environmental issues but immediately rejected any idea that our new lifestyle may involve living in just one place and driving less.
