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.
We have had very little success in reducing CO2 emissions.
CO2 emissions for all countries, in total, have been spiraling upward, year after year.

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 percent 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 “star” in emissions reductions is the former Soviet Union and its Eastern European satellites. I refer to this group as the Soviet Empire. Emissions fell around the time of the collapse of the central government of the Soviet Union in 1991. This big decrease in emissions seems to be related to huge changes that took place at that time. Instead of one country with a single currency, the individual republics were suddenly on their own.
The high point in CO2 emissions for the Soviet Empire came in 1990, the year before the collapse of the Soviet Union central government. By 1999, emissions had fallen to a level 37 percent below their 1990 level. In fact, even in recent years, emissions for this group of countries has stayed low. Much industry collapsed and has never been replaced.
The group that has more than doubled its emissions is what I call the Remainder Group. The group includes many countries, including China and India, that ramped up their manufacturing and other heavy industry in the late 1990s and early 2000s, when the World Trade Organization added members. The Remainder Group also includes many countries that suddenly found new export markets for their raw materials, such as oil, iron ore, and copper. The Remainder countries became richer; they became more able to pave roads and build more substantial homes for their citizens. With all of this GDP-related activity, CO2 emissions increased rapidly.
Population growth has followed a pattern that is in some ways similar to CO2 growth.

Figure 3. Population from 1965 to 2018, based on UN 2019 population estimates.
In Figure 3, we see that population has been virtually flat in the former Soviet Empire (2 percent growth between 1997 and 2018). With the economy not doing well, young people emigrate to countries that seem to provide better prospects.
Population in the US+EU+Japan Group grew by 11 percent between 1997 and 2018.
The group that is simply outstanding for population growth is the Remainder Group, with 35 percent growth between 1997 and 2018. A big part of this population growth comes from improved sanitation and basic medical care, such as antibiotics. With these changes, a larger percentage of the babies that are born have been able to live to maturity.
It is hard to see any bend in the trend lines, showing that recent actions have really changed the course of activity from the way it was headed previously. Of course, the trend is only “linear,” implying that the percentage growth is gradually slowing over time.
This rapidly growing population feeds into the CO2 problem as well. The many young people would all like food, homes and transportation. While it is possible to obtain some version of these desired products without fossil fuels, the version with fossil fuels tends to be vastly improved. Most people prefer homes with indoor plumbing and electricity, if given an opportunity, for example.
Deforestation keeps growing as a world problem.

High Income Countries keep pushing the deforestation problem to the poorer parts of the world. Heavily Indebted Poor Countries are especially affected. Worldwide, deforestation continues to grow.
With respect to fossil fuels, there is a great deal of confusion with respect to, “What do we need to be saved from?”
Do we have a problem with too much or too little fossil fuel? We hear two different stories.
Figure 5. Author’s image of two trains speeding toward the world economy.
Climate modelers keep telling us about what could happen, if indeed we use too much fossil fuel. In fact, the climate currently is changing, bolstering this point of view.
It seems to me that there is an equally great danger of collapse, accompanied by low energy prices. For example, we know that energy production of the European Union has been declining for many years, without the countries being able to do anything about it.

We also know historically that many civilizations have collapsed. The Soviet Empire collapsed in 1991, illustrating one type of collapse. The Soviet Union was an oil exporter. Its collapse came after oil prices were too low to allow adequate investment in new oil fields for an extended period of time. The Great Recession of 2008-2009 offers a much smaller, temporary version of what collapse might look like.
Another example of low prices accompanying collapse comes from Revelation 18: 11-13, warning of possible collapse like that of ancient Babylon. The problem was inadequate demand and low prices; even the energy product of the day (human beings sold as slaves) had little value.
11 “The merchants of the earth will weep and mourn over her because no one buys their cargoes anymore— 12 cargoes of gold, silver, precious stones and pearls; fine linen, purple, silk and scarlet cloth; every sort of citron wood, and articles of every kind made of ivory, costly wood, bronze, iron and marble; 13 cargoes of cinnamon and spice, of incense, myrrh and frankincense, of wine and olive oil, of fine flour and wheat; cattle and sheep; horses and carriages; and human beings sold as slaves.
What we have been seeing recently is falling prices and prices that are too low for producers. Such a result can lead to collapse if too many energy producers go bankrupt and quit.

If we are in danger of collapse from low prices, renewables would not seem to be of much assistance unless they (a) are significantly less expensive than fossil fuels and (b) can be scaled up sufficiently rapidly to more than replace fossil fuels. Neither of these seems to be a possibility.
Early studies overestimated how much help renewables might provide, especially if our problem comes from too little energy supply rather than too much.
Renewables look like they would be great from many points of view, but when it comes down to the real world situation, they don’t live up to the hype.
One issue is that while wind, solar, hydroelectric, geothermal, and other devices for capturing energy are called “renewables,” they are really only available through the use of the fossil fuel system. They are made using fossil fuels. If a part breaks, or if insects eat away the insulation on wires, replacements need to be made using the fossil fuel system and transported by the fossil fuel system. At best, renewables use less fossil fuels than conventional electricity generation. They are dependent on other resources, which may eventually deplete, but which are not a problem at this time.
A second issue is that it is extremely difficult to do a proper cost-benefit analysis on renewables because they can only be used as part of a larger system. They tend to look inexpensive, when viewed in isolation. But when total system costs are viewed, they often are quite expensive.
One difficulty in a proper cost-benefit analysis is the fact that renewables are often at quite a distance from where electricity is to be used, leading to the need for a significant amount of long distance transmission lines. If renewables provide intermittent power, they need to be sized for the maximum output, not their average output. All of these long distance lines need to be properly maintained, or they tend to cause fires. In some instances, burying the lines underground at significant cost is the only solution. Somehow, these higher costs need to be recognized as part of the cost of the system, but this is rarely done. Related: In Pursuit Of The Perfect Fuel
Another difficulty in a proper cost-benefit analysis is the fact that the intermittency must be overcome, if the electricity is to be of benefit to a modern economy that requires electricity 24/7/365. In theory, a person could greatly overbuild the renewables system and the transmission. This might work, but a person would end up with a large percentage of the system that is not used most of the time, greatly adding to costs.
Batteries can be added, but the cost tends to be high. One commenter on my site recently observed:
EIA reports the average cost for utility scale battery systems to be about $1500 per kWh. At that rate the batteries needed for backing up a solar or wind facility for three days cost around 30 times as much as the RE facility. But wind is often unpowered for more like seven days, during huge stagnant high pressure episodes. Thus the backup battery cost is more like 100 times the wind farm cost. Batteries are not feasible.
The major intermittency problem is season-to-season, especially saving up enough for winter. We do not have a way, today, of storing energy from one season to another, short of making it into a liquid (such as ammonia), and storing the liquid from season to season. This would be another way of driving up costs of the overall system. It has not been included in anyone’s cost calculations.
For the time being, we are forcing nuclear and fossil fuel to provide backup electrical services to intermittent renewables without adequately compensating them for their services. This tends to drive them out of business. This is not an adequate solution either.
A third inconvenient truth about renewables really need to be “economic” to work. In other words, they need to generate a profit for their owners, when comparing the unsubsidized costs with the benefits of the system. In fact, their owners need to be able to pay fairly substantial taxes to governments, to cover their share of governmental costs as well. If renewables truly were providing substantial benefit to the system, their use would tend to “take off” on their own, because they would be providing “net energy” to the system. Instead, renewables tend to act like “energy sinks.” They need endless subsidies. They can never substitute for fossil fuels. In fact, they can’t even pay their own way.
A related issue is that, because of the high total costs (as well as their lack of true net energy benefits), it is almost impossible to ramp up the quantity of renewable such as wind and solar very high. The EU has been a big supporter of renewables other than hydroelectric. Figure 7 shows a chart of the EU’s own energy production, together with its energy imports.

Figure 7. EU energy by type and whether imported, based on data of BP’s 2019 Statistical Review of World Energy. Renewables are non-hydroelectric renewables such as wind, solar, and geothermal.
After at least 20 years of subsidies, the EU has been able to increase renewables (other than hydroelectric) to about 10 percent of its total energy supply. The EU’s oil imports are roughly level, and its natural gas imports have been increasing. Even with rapid growth in non-hydro renewables, the EU has been experiencing a decrease in total energy consumption.
Looking at the actual outcomes, a person might ask, “What in the world were policymakers really thinking about?”
We are told that the reason policymakers made the decisions they did was because they thought that they could reduce CO2 emissions in this way. Really? If a person really wants to reduce CO2 emissions, it is easy to see how to do it. A person simply has to take steps in the direction of reducing global co-operation. One step would be to reduce international trade. Another would be to get rid of umbrella organizations such as the World Trade Organization, the United Nations and the European Union. In fact, within individual countries, the top level of government could be removed, leaving (for example) the provinces of Canada and the states of the United States. In other words, policymakers could push economies in the direction of collapse.
Another way collapse could be encouraged would be by rapidly raising interest rates or cutting off credit. With less purchasing power, the world would be pushed into recession.
At the time of the Kyoto Protocol, policymakers moved in precisely the opposite direction of pushing the economy toward collapse. They moved in the direction of adding international trade and more debt to enable the growth. The countries with greater trade had huge coal resources that had not been used. With the help of this coal, the world economy was able to continue to grow. This approach only made sense if the real problem at the time of the Kyoto Protocol in 1997 was too little energy resources, not too much. The economy needed the stimulation that more low-cost energy and more debt could provide.
It is now more than twenty years later. The coal resources of China are starting to deplete. Coal is also causing serious ground-level pollution problems, both in China and India. Without growing coal production, world GDP growth starts slowing. We are again facing low oil prices and other commodity prices–a problem similar to the one present when the government of the Soviet Union collapsed. The world economy seems again to be headed toward having some of its governmental organizations collapse from inadequate energy. Political parties are becoming more extreme; countries are enacting new tariffs. If we go back to Figure 5, the concern should again be collapse, on the left side of the figure.
The IPCC climate models need to be revisited.
A climate model looks to the past and tries to forecast the future. When the IPCC models were put together, the scenarios about which concerns are raised are based on the assumption that fossil fuel use can grow practically indefinitely. Coal production in particular is seen as continuing at a high level for many, many years, even though world coal production has been fairly flat for several years, and prices tend to be lower than producers require if they are to stay in business.

Figure 8. World Energy Consumption by Fuel, based on data of 2019 BP Statistical Review of World Energy.
In order for coal production to grow as much as modelers forecast, there needs to be a major turnaround in the situation. World coal prices need to rise substantially. In fact, coal in very difficult locations for extraction, such as under the North Sea, need to become profitable to extract. This situation seems very unlikely.
It seems to me that climate modelers should be considering more reasonable scenarios regarding fossil fuel consumption. One scenario which should be considered is the possible near term collapse of several governmental organizations, such as the European Union, World Trade Organization, and the governments of several oil exporting countries. Such a model would be more realistic than one in which energy consumption continues to grow indefinitely.
The push toward renewables makes little sense without a firmer foundation than currently exists.
Early studies looked only at the cost of renewables themselves, without the cost of extra long-distance grid transportation and battery storage. This could be one of the biggest problems with renewables. Such an estimate makes renewables look far more valuable than they really are.
We now have enough experience that we can see what goes wrong. A hydroelectric plant that operates during the wet season in a tropical country may be of little practical use, for example, if there is no fossil fuel energy to provide electricity production during the dry season. The total cost of the overlapping systems is needs to be recognized, including the need to hire staff year around for fossil fuel and hydroelectric facilities. Electricity transmission will likely be needed for both types of generation.
There are many other real-world examples that can be examined, before blanket “use renewables” recommendations should be issued. If renewables are not truly very inexpensive (around 2 cents per kWh or less), without subsidies, they are likely not to be long-lasting.
