Do the World’s Energy Policies Make Sense?

The world today has a myriad of energy policies. One of them seems to be to encourage renewables, especially wind and solar. Another seems to be to encourage electric cars. A third seems to be to try to move away from fossil fuels. Countries in Europe and elsewhere have been trying carbon taxes. There are also programs to buy carbon offsets for energy uses such as air travel.

Maybe it is time to step back and take a look. Where are we now? Where are we really headed? Have the policies implemented since the Kyoto Protocol in 1997 had any positive impact?

Let’s look at some of the issues involved.

[1] We have had very little success in reducing CO2 emissions.

CO2 emissions for all countries, in total, have been spiraling upward, year after year.

World CO2 Emissions

If we look at the situation by part of the world, we see an even more concerning pattern.

The group US+EU+Japan has been able to reduce its CO2 emissions by 5% since 2005. Emissions were slowly rising between 1981 and 2005. There was a dip at the time of the Great Recession of 2008-2009, followed by a downward trend. A person might get the impression that CO2 emissions for the EU tend to rise during periods when the economy is doing well and tend to fall when it is doing poorly.

The climate change story is half true

The climate change story is true in some respects: The climate is indeed changing. And CO2 emissions do seem to affect climate. Burning fossil fuels does indeed make a difference in CO2 levels.

The problem I have with the climate change story is that it paints a totally inaccurate story of the predicament the world is facing. The world’s predicament arises primarily from too little affordable resources, especially energy resources; climate change models tend to give the illusion that our problem is one of a superabundance of fossil fuels.

Furthermore, the world economy has no real option of using significantly less energy, because the economy tends to collapse when there is not enough energy. Economists have not studied the physics of how a networked economy really works; they rely on an overly simple supply and demand model that seems to suggest that prices can rise endlessly.

The quantity of energy supply affects both the supply and demand of finished goods and services. History shows that the result of inadequate energy supplies is often collapse or a resource war, in an attempt to obtain more of the necessary resources.

Climate scientists aren’t expected to be economists, but have inadvertently picked up the wrong views of economists and allowed them to affect the climate models they produce. This results in an over-focus on climate issues and an under-focus on the real issues at hand.

Let’s look at a few issues related to the climate change story. Continue reading

Oil Limits and Climate Change – How They Fit Together

We hear a lot about climate change, especially now that the Intergovernmental Panel on Climate Change (IPCC) has recently published another report. At the same time, oil is reaching limits, and this has an effect as well. How do the two issues fit together?

In simplest terms, what the situation means to me is that the “low scenario,” which the IPCC calls “RCP2.6,” is closest to what we can expect in terms of man-made carbon emissions. Thus, the most reasonable scenario, based on their modeling, would seem to be the purple bar that continues to rise for the next twenty years or so and then is close to horizontal.

I come to this conclusion by looking at the tables of anthropogenic carbon emission shown in Annex II of the report. According to IPCC data, the four modeled scenarios have emissions indicated in Figure 2.

Reaching Limits to Growth: What Should our Response Be?

Oil limits seem to be pushing us toward a permanent downturn, including a crash in credit availability, loss of jobs, and even possible government collapse. In this process, we are likely to lose access to both fossil fuels and grid electricity. Supply chains will likely need to be very short, because of the lack of credit. This will lead to a need for the use of local materials.

The time-period is not entirely clear. Some countries, such as Greece and Syria, will be seeing these effects quite soon. Other countries may not see the full effects for perhaps ten or twenty years. What should our response be?

It seems to me that there are many different answers, depending on who we are and what our goals are. The various options are not mutually exclusive.

Option 1. Make the most of the time we have available. Continue reading
