This is simply a stupid take. This is obviously a test piece and eventually renewables will take over and the power grid will become clean. Arguing for any other way forward is idiotic, for the life of me I will never understand why people are so enamored of old technology.

So any kind of criticism is now offensive and counterproductive? What renewables are you taking about? Let’s just clear the air. Is the current way better? Fuck no. Can it be better? Hell yes. Old technology built this modern world. Improving old tech with new tech is the way forward. Case point: Asbestos. Everyone and their momma rave and ranted, it was all over Popular Mechanics, and countless Engineering articles. A few decades later what have we found?

Definitely not what I said, I never implied all criticism was bad, I only said that your point was stupid, which it was. Also renewables are largely solar, with some wind, hydro, and geothermal mixed in where appropriate. Solar is everywhere now, and it’s big money because the utilities can buy the power from a solar farm cheaper than they can generate it from fossil fuels.

Oh good solar. How good is your math? Simple math problem what is the output required to recharge an EV? How many hours in the day is it good for? Wind power: it’s a good source, if space is available. Geothermal, who has it? Hydro, that is actually very sustainable. Yet it’s geo locked to rivers and flooding a good size valley. You should be able to answer that right. It’s simple.

Jesus Christ do you know what a battery is? I literally work in Solar the output is whatever you want it to be based on the field size and whatever transformer you’re using, with a battery storage system it can output all night too. I have no idea where you’re getting the idea that EV’s have this crazy charging requirement that can’t be met, it just isn’t true.

So you don’t know math is what you are telling me. It really is a math problem. You clam to work in solar, are you a salesman? Must because you can’t answer a math problem. I’ll help you out a bit. How much kWh can 1 solar panel produce in a day. Now figure out what size kWh battery you want to charge. Do the math. You can do it. I’m rooting for you.

Oh you didn’t try to answer the other renewable energy questions. At lest name one geothermal power plant.

You clearly don’t know Solar because you’re asking about mWh from a single panel, then you’re asking about the battery size? The battery is sized to the field. If it’s a 500 megawatt site (which is a small one competitively) then the battery will be sized accordingly so that the site charges it during the day and then discharged at night to keep power flowing into the grid.

An EV will take about 50kWh to fully charge, and that can be done with a single 50kw string inverter and about 150 individual Solar modules (panels). So with a single inverter (there are literally hundreds on some sites) I can fully charge an EV in less than 30 minutes with a super charger.

And before you give me shit saying about the dumb wall charger taking way longer, yes but it will use the same amount of power overall to charge the vehicle because it’s still the same amount of wattage.

You keep acting like there’s some magical math equation that makes you right and there isn’t because you’re not.
