Considering they only generate energy at about 30% of their rated capacity(1), and early electric vehicles(2) like tesla model S can have 100Kwh batteries already, can anyone do the math for the quantity of windmills needed for the volume of cars on the road?

(1) due to unstable winds, minimum start up speeds, maximum outsput caps, and high speed termination to save them breaking.

(2) by early electric vehicles, I mean as battery tech evolves past lithium ion to contain more electrical energy, this question will be even more unrealistic and retarded.

Now let's see how much kwh an average windmill uses... a basic search gives us a rate of 400k kwh a month. Pets just be generous and round to 5 million kwh annually.

The average turbine size in the US is 2.43MW with an average capacity factor of 42%. That means, on average, each wind turbine in the US produces the equivalent of a little over 1 million watts. That's 8,940,456 kWh per year per turbine. Some more, some less.

Now we have to figure out how many kwh an electric car uses to move 100 miles.... average is 30kwh for 100 miles.

The EPA rating for electric cars is around 25 kWh per 100 miles, and many people get more than that. The fleet average is including heavy vehicle like buses and trucks, and is skewed because of the relatively high annual mileage of commercial vehicles.

Then finally let's find out how far America drives in a year... the quick search I just made gave me 3 trillion miles

In 2018, there were 1,404,507,000,000 passenger vehicle miles driven in the US.

So 1,404,507,000,000 miles requires 351,126,750,000 kWh, or 39,273 wind turbines. The US currently has about 67,000 wind turbines, so we'd need to increase it by 50%.

Im not going to argue your number because I don't care about the question. I put in a search for each number set and popped in the first answer that came up into the equation. It took less than 5 minutes.

because I don't care about the question.

So why even bother if you knew you'd be wrong because you don't care. What kind of retarded logic is that.

I just explained to you I put the questions into search, put the first answer in, and did the math. Can you read? Do you understand English? Apparently you numbers should be questioned because if you're having this hard of a time understanding basic concepts when they are communicated to you then I doubt you can work a search engine properly or remember which mathysymbolthingy is for what. Fuckin retard
