Shale oil and gas fraud: A sign of a peak in oil supplies? - Resilience

IF a true peak in crude oil reserves ever occurs that may usher in real interest in renewable forms of energy.

Looks like another anti oil group.
A lot of gas and oil is coming out of the shale, and is powering the plants that charge the electric cars.

Every time you convert energy, you have losses. In the end, electric vehicles are probably less efficient, when you look at the whole energy path. Hybrids seem to make the most sense, but they were overpriced compared to ice and the cost of gas.

When Honda first came out with a Hybrid accord, it got 1 mph better than an accord with a standard transmission, for over $10k more in cost. You would never break even.

As far as government studies, btdt, we were often told by govt officials to support such and such result. They were usually about siding with the answer that produced the most funding. If you didn’t produce what they wanted, you got no more work. They would find another “yes” man.

If you keep the car through a battery change-out how would it change the chart?

Did you track down the inputs to the study to answer your question? I'd be interested to hear.

I looked at the matinance items listed and conveniently the battery replacement was missing. Very bias.

I agree 100% but throw in the 60s for an added punch.

Difference then was, people were somewhat better educated but mostly, not so many whackos with guns.

IMHO

Yeah, late 60s early 70s. Terrorists like the Weathermen were blowing up buildings, the army (or whoever) was shooting unarmed college kids at Kent State, we were bogged down in an unwinnable war with riots attended by hundreds of thousands of people burning flags, etc. I think the biggest difference was no Facebook and MSNBC/Fox News back then. If we had today's 24 hour sensationalist news cycle and social media back when all that was going on people would have thought the world was ending before their very eyes. But eventually sanity returned and people got on with their lives, just like they'll do with our current covid-fueled blip of riots and outrage by people with too much free time on their hands.

For EVS produced in the last 5 years there is no change out charges until after 8 years or 100,000 miles. Nissan Leafs had battery pack failures through 2017 especially in mid 90 summer temperatures. Our 2016 Leaf SL 30 kWh Battery Pack State Of Health dropped under 65% 5 weeks after I got it home late 2019. Nissan replaced it with a 2020 40 kWh battery with different chemistry. Their 2018+ 40 and 62 kWh packs seem more stable.

Nissan never had any battery cooling system but did Ok in Canada, Norway etc.

Oftentimes non EV owners fearful of new technology tend to make fake post about EV cost of ownership.

Today Tesla is the only EV made based on field proven EV technology today. Well BDY of China is a serious option and is the EV that Warren Buffett is behind. They have a factory in California where they built city buses. They are into heavy trucks buses like garbage trucks etc and are getting some strength in cars currently. Toyota plans to put their own car bodies on BYD EV skateboard.

I am hoping the $25,000 Tesla will have headroom so I can get in it. The size of the Leaf works great for our needs but it's just not a serious EV for the log haul.

GrumpyCat is a 2013 Tesla Model S owner so he knows about EV battery life after all these years.

I read that article that describes how this study contradicts another study with an opposite result. It also didn't take into consideration a higher demand of electricity would ordinarily drive the cost of electricity up.
Sounds more like bias reporting from the government.

Meh. EV demand for electricity will drive prices down because the demand will be at night when there is great surplus that can’t be sold. That T.O.U. billing discounts nighttime consumption because the utility would rather get something than nothing.

It sounds like you get a discount for electric use at night. I don't and I don't see why they would start that policy. That's kind of like gas stations giving you 10 cents off after 10:00 p.m. when it's slow, I haven't seen it. Time will tell but I don't see my electric prices going down in my lifetime. I think it's common knowledge that electricity customers use more electricity now than they did 30 years ago and the price has gone up not down. More likely due to the laws of supply and demand, electric rates will go up.

GC what is the cost for a battery replacement?

We don't either. In fact we are a green energy town - we got kudos from Kerry (look up Georgetown TX) - and at night the solar panels and wind turbines are the least productive. Night time energy is dirty natural gas or coal energy.

I do not but I know much of the country does and my utility keeps trying to get it approved. In recent years they replaced all electrical meters with networked smart meters which makes T.O.U. possible. I can check my usage by the hour, the most recent hour, online.
