Irina,

For thousands of years, humanity sustained on the power of sun and sail. The solution to intermittently is actually right in front of us - the hydrocarbon batteries that nature herself builds, whether she does it in 20 years (a tree) or 200 million years (oil, gas, coal)

The problem with the transitionists is that they envision a future which is a low energy, carbon free world. If they were serious, there would be a proliferation of nuclear power like nothing else. But they openly state that such sources of unlimited energy would make the problem (?) worse.

I suppose it is fortunate the economic hardship is coming sooner rather than later, before these idiots do more damage. Then again, when has civil discontent ever deterred True Believers

Ms. Slav,

Thank you (again) for exposing the ever growing package of lies told by these sociopaths. Allow me to tackle the issue of EVs by repeating a post I put on Mr. Blackmon’s Substack earlier this week:

My apology, in advance, for this lengthy comment. You raise excellent points that I need to elaborate on. Why 38% of energy executives still believe in zero carbon by 2050 may be explained by their age, and hence, poor education. For years, our educational systems have been conscripted by propagandists. Basic chemistry, mathematics, and physics, are shunned along with literature. Students have been raised as "activists", not scientists. Here is the reality of electrification of all things transportation, it will not happen.

I'm not seeing EVs ever taking over the wheeled transportation business, or even equaling what they were at the turn of the twentieth century. That was an attempt in the first version of auto/truck development, with almost one-third of all cars on the road being electric! That reversed, and lost out then for the same reasons as it will today. The energy density of gasoline and diesel is just too overwhelmingly favorable. The other thing we have to remember is this. Electricity is not a "compound" that exists in nature like hydrocarbons or uranium. It has to be generated by some mechanical means, usually powered by hydrocarbons, in order to exist. Once it comes into existence, it must be either used immediately, or stored in a very inefficient way (battery), and each of these steps is subject to loss from transformation.

Just the gyrations of generation to motive force is unbelievable. Consider the entire process:

1. Power plants produce alternating current (AC) electricity, that is stepped up to tremendous voltages (155,000 up to as much as 765,000) using transformers for long distance distribution (the grid). Why not Direct Current Generation? Because of HUGE losses of energy over long distance transmission. (This was the origin of Mr. Nikola Tesla, beating his old boss Thomas Edison and winning out with an AC electric distribution standard over Edison's DC system.)

2. Local transformer stations reduce that voltage for area distribution,

3. Neighborhood transformers either on the pole in your backyard, or in that green box if your neighborhood has underground electrical service, reduce it further to 480,240-, and 120-volt feeds, still all AC, for use.

4. Now comes the Tesla (or any other EV charger) that has to take that AC current and run it through a transformer/rectifier/conditioner that for large loads could even involve mechanical energy rectifiers (like large electric motors) to get the voltage transformed to Direct Current (DC) that is needed to charge the battery. The battery only stores and then gives up direct current (DC). It cannot do anything with Alternating Current.

5. Once the battery is charged, the car's onboard inverter must convert the high voltage DC from the battery back into high voltage (400-600 volts depending on the brand of car) ALTERNATING CURRENT (AC) to drive the Alternating Current Inductive motors that turn the wheels. Why don't the EVs just use a DC motor to turn the wheels? Because DC motors that produce a lot of power are much less efficient as compared to AC inductive motors and the solid-state controllers that we have today.

6. Using the brakes in the car turns the Alternating Current (AC) inductive motor into an alternator (an AC current generator) that then runs the AC current through onboard transformers/rectifiers/conditioners to change back to DC current to put back into the battery. This "dynamic braking" is why the friction brake material in EVs lasts much longer than internal combustion engine cars, and lifting your foot off the accelerator pedal is a bit like stepping on the brakes in a conventional internal combustion engine car.

Now, count the steps above, and remember, at each one of them, there is energy loss through heat, mechanical friction, or electrical resistance. You cannot change AC to DC, DC to AC, voltage to current, current to voltage and make all of this happen without significant loss.

This isn't really news. It is just chemistry and physics, neither one of which has changed from the time of the early 1900s.

And all of the above happens AFTER you have spent thousands of gallons of hydrocarbon fuel mining, transporting and refining the cobalt, lithium, antimony and "rare earth elements" that go into EVERY EV battery and EVERY high energy AC inductive motor!

WAY TOO ENERGY INTENSIVE, and WAY TOO DIRTY for the environmentalists who understand this process, and way to expensive economically to be anything but a fool's dream.
