E10 fuel (90% gasoline/10% ethanol) has a source energy, which is reduced due to extraction, processing and transport, to become the primary energy fed to E10 vehicles. As a result, the energy fed to the tank has to be multiplied by 1.2639 to obtain source energy.

Electrical energy has a source energy, which is reduced due to extraction, processing and transport, to become the primary energy fed to power plants, which convert that energy into electricity, which after various losses, arrives at use meters. As a result, the energy fed to the meter has to be multiplied by 2.995 to obtain source energy.

The below “40 mpg, EPA combined” table shows, high-mileage E10 vehicles, including hybrids, such as the 52 mpg Toyota Prius, have greater energy efficiency than EVs, and only slightly greater CO2 emissions than EVs. It would be much less costly and quicker to significantly increase the US hybrid fleet, than to build out the EV fleet, which is still in its infancy, and would require major, expensive changes to supporting infrastructures.

To start, despite a huge workforce of almost 400,000 solar workers (about 20 percent of electric power payrolls in 2016), that sector produced an insignificant share, less than 1 percent, of the electric power generated in the United States last year (EIA data here). And that’s a lot of solar workers: about the same as the combined number of employees working at Exxon Mobil, Chevron, Apple, Johnson & Johnson, Microsoft, Pfizer, Ford Motor Company and Procter & Gamble.

SB 700 would require utility companies to collect even more funds from ratepayers to help establish an Energy Storage Initiative, an ESI. This ESI would work in conjunction with the existing Self Generation Incentive Program that has been so successful in California. The ESI would need to be funded through 2027.
