The average electric vehicle uses 0.32 KWhs of electricity to go a mile.  Since the average residential for power is $0.17/KWh, that’s $0.06 per mile.

This compares favorably to gasoline, whose average use per mile is 0.04 gallons at an average cost of $3.64, or $0.15.

Over the lifetime of a car, say 200K miles, we’re talking about $18,000.

Now, there are other pros and cons at stake here.  Replacement batteries for EVs are expensive, but the savings in terms of entire systems that are eliminated in EVs (fuel delivery, engine parts, pollution control, exhaust, etc.) are considerable as well.

Of course, the major motivation behind EV purchases is environmental responsibility.  Studies have consistently shown that phasing out internal combustion engines and the consumption of fossil fuels is essential to the decarbonization of the energy and transportation sectors, and thus to the success of our society’s efforts to mitigate climate change.

Myth Busting in Renewable Energy

I met a guy earlier today who told me that wind and solar are controversial, and that some people say that the mining and manufacturing of wind turbines requires more fossil fuels that the turbines themselves produce.

I told him that I’m aware of such people; they’re called “professional liars.”

I explained the concept of EROI, energy return on investment, and surprised him by saying that the EROI of wind is somewhere between 18 and 30, meaning that each wind turbine you see as you drive along the freeway will generate at least 18 times as much energy as was required in its mining, fabrication, installation, maintenance, and decommissioning–all the way up to 30 times that amount.

The generation of disinformation of renewables has become a cottage industry.  People are paid to make up and publish complete bullshit, so as to discredit the burgeoning clean energy industry, and keep Big Oil in place.

Thanking God for Trump

As bad as things are in the United States, they could always get worse.

Trump could succeed in his quest to be a dictator, Christianity could be taught in schools, and unvaccinated adults and their kids could trigger another epidemic.

In terms of our reputation on the world stage, however, things really can’t get must worse; the countries around the globe already regard us with a mixture of hate and derision.

Yet regardless of what the future holds, there will always be idiots who that believe that Trump is our savior, like the author of the meme above.

Good to see John Eastman disbarred in California; it’s a small measure of justice.

Criminal prosecution in the future?
