RE proponents want to “electrify” the Vermont transportation sector. That means:
- Much less consumption of gasoline and much more generation of electricity.
- Internal combustion engines using gasoline, hereafter called E10 (a blend of 90% gasoline/10% ethanol from corn), would be replaced with electric vehicles.
For this article, it is assumed only EVs will be used to replace IC vehicles that currently are using gasoline. Hybrids would not be allowed,…Continue

The EPA has a unique method of calculating MPGeq. The method is used nowhere else in the world.
The EPA arbitrarily sets the lower heating value, LHV, of gasoline at 115,000 Btu/gal.
Then EPA states 115000 Btu/(3412 Btu/kWh) = 33.7 kWh.
BTW, the LHV of E10 (a blend of 90% gasoline/10% ethanol) is 112114 Btu/gal.
When testing an EV, the EPA measures the kWh (AC) from a wall meter.
The vehicle state-of-charge meter measures the…Continue

Primary Energy Sources Requiring Combustion
Source energy is the energy taken from the earth, such as from a well, a mine, a forest. The energy for exploration, extraction, processing and transport is used to convert the source energy to primary energy for the US economy. The US electrical system uses about 40% of all primary energy.
- Source energy is the energy taken from coalmines, oil and gas wells, and forests for conversion (by means of…Continue
