"this rule does not correctly describe the most common usage of today or the past and in fact arose as an incorrect generalization of a personal preference expressed by a grammarian in 1770"

They claim renewable is 5p/kWh. Funny how that is not what I'm paying.

I have senses, I can tell the temperature when I go outside. It's the same as it always has been.

It most certainly does not, I used to be able to choose green energy form my supplier, it cost more. They had green, standard, and nuclear. I chose nuclear as it was the cheapest.

I don't live there, I don't care.

Wow, you must be really rich.

He is just parroting what his liberal leaders tell him.

That is one view, certainly. That is why we need to get rid of non renewable. The problem is that the market for Electric cars has built up fast, but the ability to generate from renewable takes time and of course is not available all the time, meaning we need a back up. Yesterday I watched a programme about electric aircraft that used hydrogen fuel cells for cruise, but batteries at take off. So how are they making this hydrogen, I said to the TV, but nobody told me. Its a quite energy intensive job at the moment of course, so until its not, I fear they are never going to be able to use fuel cells, never mind the problem of their inefficiency, producing heat as a by product of converting hydrogen into water and electricity, but using oxygen from the air of course.

Are you sure you want that? In this country 81 million people allegedly voted for a senile politician who was incompetent on the best day of his career.

That has its problems also.

400 Ph.D economists, including Yellen, and none of them saw inflation as the outcome of pouring money into the economy?

Ice is being gained at the south pole

Numpty

No one had any better choice.

Deluded.

So you aren't really blind after all.

about electric aircraft that used hydrogen

You live in Florida down around N28.5, right?

In my field we call it vaporware... The schematic shows the hydrogen being produced by electrolysis, compressed, and stored in tanks on the aircraft.

The first problem is green hydrogen production is currently expensive. Green hydrogen accounts for about 1% of production. The rest is made by steam reforming of natural gas, a fossil fuel.

Then the hydrogen must be compressed to around 10,000 psi. Carbon fiber technology has made the tanks more efficient but it's still around a ten to one ratio; i.e. a tank capable of holding 1 lb of hydrogen weighs 10 lbs. That's a problem for terrestrial vehicles let alone aircraft.

Then there is the need for rare metals as catalysts both for the electrolysis and in the fuel cells.

Sure, it's all possible but I doubt it will happen in my lifetime.

The brainless electing the brainless.

No matter the employer, and I have seen it with PhD scientists, people tend to give the boss the answer he wants. I gave the story of the state climatologist that said, when Mother Nature comes, you have to get out of her way, being fired by the state Democrat governor.

-------------------- We should stop making flu, MMR, & Covid shots, to shorten the average life span by a few years, because we didn't listen to the scientists who called for Zero Population Growth 50 years ago! When you go too far out on a limb, you need to back up!

----------------------------- The experts called for Zero Population Growth 50 years ago! Nobody listened!

What you and others neglect are all the extra resources needed to make the cars not to mention the windmills and solar panels.

27.49 to be specific. Florida Power and Light is installing a large batter pack too.

What you and others neglect is the studies that showed the facts from cradle to grave EVs use less.

oh yea , where you going to get those
