Economic Work per Unit of Energy

Conservation: 80% of Oil is Waste

The average American uses 88 megawatt-hours per year, the average German uses 47. Americans can cut our energy use in half and still have an advance economy. Cutting our energy use in half by 2019 is the path to solving the Civilization Killers currently facing America.

Driving a car costs about 59.2 cents per mile. JPods vehicles operate a 4 cents per vehicle-mile. Energy and costs are highly correlated. The chart below compares energy per passenger-mile for various modes of transportation. 

Calculations of fuel efficiencies and DOE Energy Use

FTE is Freight Train Equivalent. The 140,000 miles of freight railroads in the US average 476 ton-miles per gallon of diesel. This is over 140 times the efficiency of moving a ton to move a person in a car on highways. In contrast to the efficiency of rails networks, the government highway monopoly retains the efficiency of the Model-T.

USAToday  February 6, 2015.

The average gas mileage of all cars and trucks sold in the U.S. in January was 25.4 miles per gallon. While that was up from 25.1 mpg in December, it was down from August's all-time high of 25.8 mpg. As gas prices have slid, more people have been buying larger, more fuel-thirsty vehicles.

Electric cars actually create more pollution in their life-cycle than diesel cars. Highways networks require people to spend $8,876 per year per car for something that is parked 95% of the time.

We need a better know-what.

 

JPods uses solar to power our networks.

In this example, energy required per passenger-km is .89 watt-hours. This illustrates the efficiency of rail. This vehicle carried 3 people without air conditioning and other creature comforts required for commerical systems. Still this is a good example of efficiency hundreds of times better than highway networks.
