Somehow, people seem to believe that our economy of 7.5 billion people can get along with a very short list of energy supplies. This short list will not include fossil fuels. Some would exclude nuclear, as well. Without these energy types, we find ourselves with a short list of types of energy — what BP calls Hydroelectric, Geobiomass (geothermal, wood, wood waste, and other miscellaneous types; also liquid fuels from plants), Wind, and Solar.

Unfortunately, a transition to such a short list of fuels can’t really work. These are a few of the problems we encounter:

[1] Wind and solar are making extremely slow progress in helping the world move away from fossil fuel dependence.

In 2015, fossil fuels accounted for 86% of the world’s energy consumption, and nuclear added another 4%, based on data from BP Statistical Review of World Energy. Thus, the world’s “preferred fuels” made up only 10% of the total. Wind and solar together accounted for a little less than 2% of world energy consumption.
