Ok, 25% of 27.5q BTU = ~ 7q BTU

So we need extra 7q BTU of electricity, right? Which is about 18% of 37.8!

So, not 7, not 9, we would need at least 18% extra electricity.

TLDR: Your math was wrong!

Unless you show us data on how much %age of total energy usage is electricity, there is no relation between the two!

According to some sources, electricity accounts for about 20% of total energy usage. So with your numbers, we would need extra 6.75% of total energy used. 6.75% of 20% is an extra 33.5% of electricity.

> We know how many BTU equivalent are used for electricity generation vs gasoline for transportation. And how much BTU equivalent is needed to power electric cars.

Show us the data.

> There is.

There is literally no relation.

"Cars use 27% of total energy in US. And 25% of 27% is equal to 7% of electricity generated." HOW??

> Petroleum for transportation currently accounts for 27% of US energy usage

> 25% * 27% = 7% more electricity

There is no relation between amount of petroleum used and amount of electricity generated in the data provided by you. All you can say is we need the equivalent amount of 7% extra of total energy used today. You did not provide any data about how much of total energy used is electricity . If electricity is 7% of total energy usage, then we need 100% extra to charge all the cars.

TLDR: your math is wrong.

Terrible terrible analogy. It would be correct if EU was asking apple to make their phones be able to use Intel processors.

A correct analogy would be if BMW was taking a 30% cut from anyone selling seat covers for for BMW cars and EU telling them to not do that.

Imagine your child taken away from you just on the basis of some assumptions. This makes my blood boil. I have never had murderous thoughts even when I have been wronged really bad. I just forget and move on with life. But I don't think I can do that if my child is taken from me for something I didn't do. I'll definitely go postal. Land of "Freedom".

>> Total cholesterol and mortality by sex and age:

They should have done the study based on gender, rather than sex. This study is discriminatory against trans people so its inherently anti-trans.

There's always room for more automation. Tesla, for example, is much more automated in many areas.

Things change over time. China and India have been having multiple talks over the last few years (after the Galwan incident) to resolve their border dispute. The ceasefire has lasted for decades now. Neither country wants war. Of course there will always be a dispute, but a long long term line of actual control will be determined and respected by both sides without giving up their respective claims.

And then you wonder why the crypto keeps going up (I'm talking about long term trends). Many believe that the 2016/2017 spike in crypto coincided with the Indian demonetization of November 2016, when the Indian govt. declared all currency notes to be invalid.

To his credit, Narendra Modi has increased ISRO's budget a lot. Many years they have received more than promised! So he kind of deserves to rake in the limelight.
