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% 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.
