The United States Department of Transportation tells us in their online report “Public Transportation’s Role in responding to Climate Change” that we should use public transportation to reduce our greenhouse emissions. This claim is also made in Time’s “Global Warming Survival Guide.” Even the CDC (Centers for Disease Control and Prevention) recommended public transportation, in 2017, as “one of the best ways to reduce greenhouse emissions.” Public transportation does reduce congestion during peak traffic hours, but data from the National Transit Database suggests that cars are cheaper and use less fuel per passenger-mile traveled, so this claim is suspicious. Let’s examine it.

The purveyors of greenschist (a geologically inspired euphemism for green sh!t) seem to have an obsession with a phrase that they clearly do not comprehend: Tipping point.
Electric Cars Reach a Tipping Point
Sep 10, 2017
Say goodbye to gasoline. The world’s slow drift toward electric cars is about to enter full flood.
China, one-third of the world’s car market, is working on a timetable to end sales of fossil-fuel-based vehicles, the country’s vice minister of industry and information technology, Xin Guobin, told an industry forum in Tianjin on Saturday. That would probably see the country join Norway, France and the U.K. in switching to a wholly electric fleet within the lifetime of most current drivers.

It is difficult to compare 1840 to 2015, so much of what we have today didn’t exist then. But, they had to move people and goods from place to place as we do now. They had farms then as we do now. They used wagons pulled by horses, mules or oxen. We use cars and airplanes. They used muscle power to farm, we use tractors, combines, grain carts, and trucks powered by petroleum fuels. In 1840 crude oil and natural gas production and use were rare. Coal was used in manufacturing, but steam engines were still in their infancy. So the world in 1840 was fossil fuel free for the most part. Biofuels, that is burning wood and dung, were common. Windmills would not appear until 1854. Hydropower was not in common use until after 1849. Solar power had not been invented yet.
The cost of gasoline can be seen on the sign at any gas station, but what is its value? Using gasoline or diesel saves us time and manual labor. It also saves air, water and waste pollution. Let us not forget that the automobile was lauded as a great environmental improvement after the “Great Horse Manure Crisis” of 1894. Nothing like having horse manure up to your knees to help you appreciate gasoline!
How much manual labor is replaced when we use gasoline? In other words what is the value of gasoline? In large part our standard of living is determined by the difference between what we pay for petroleum fuels and coal and their value in time and labor. I’ll try and compute that value by comparing a 1,812 mile trip, along the Oregon Trail from Independence, Missouri to Oregon City in 1840 with a trip today. I’ll also compute the value of diesel by comparing a 10 acre grain harvest in 1840 to a harvest today.
