The “Wind and Solar Will Save Us” story is based on a long list of misunderstandings and apples to oranges comparisons. 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:
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.
Our progress in getting away from fossil fuels has not been very fast, either. Going back to 1985, fossil fuels made up 89% of the total, and wind and solar were both insignificant. As indicated above, fossil fuels today comprise 86% of total energy consumption. Thus, in 30 years, we have managed to reduce fossil fuel consumption by 3% (=89% – 86%). Growth in wind and solar contributed 2% of this 3% reduction. At the rate of a 3% reduction every 30 years (or 1% reduction every ten years), it will take 860 years, or until the year 2877 to completely eliminate the use of fossil fuels. And the “improvement” made to date was made with huge subsidies for wind and solar.
