Odd I thought the Germans are pretty good at that. They claim to be!

The UK ""There is definitely enough energy and the grid can cope easily,” he explains. “The growth in renewable energy means this is not static and smart metering will make this more efficient. For example, the growth in wind power from the extra offshore wind farms being developed will adequately meet the future demand for electrifying transport – an extra 100 terrawatt hours from our current 300 terrawatt hours consume.

There is definitely enough energy and the grid can cope easily. Link

"Preparations have been underway for a while, as we’ve been discussing how best we can work towards the green transport changeover with government, electricity distribution companies, who transport the energy from the grid to homes and businesses, service station operators and charge point providers for over two years.""

Australia "These concerns are not completely unfounded. Modelling and research at the University of Melbourne, conducted as part of a project led by Professor Iven Mareels, has shown that in Victoria even fairly modest rates of electric vehicle uptake could have a major impact on the electricity distribution grid.
However, these problems would be caused by uncoordinated charging, with battery recharging occurring as soon as the driver returns home and plugs in the car. With some simple coordination – perhaps using smart meters – Australia’s grid can easily support far more electric vehicles for decades to come." Link

"We set out to investigate the validity of most of the latter concerns, and to quantify the potential benefits of transport electrification. Our study, which has been published in the Australian Journal of Electrical and Electronics Engineering (https://goo.gl/RtCFsq), used existing travel data from the NSW Household Travel Survey 2014/15.We found that approximately 90% of vehicle commutes within most parts of Sydney are less than 40 km, so concerns about the limited range of EVs are largely unfounded. In fact, 88% of all vehicle commutes within Sydney could be serviced by existing low- to mid-range fully-electric vehicles costing up to $40,000. This result was surprisingly similar to a study published in Nature Energy which estimated that 87% of commutes across the United States could be provided by mid-range EVs (https://goo.gl/dggmPU).
The pattern of arrival times of vehicle trips shows that vehicles were parked at home for about 10 hours overnight, which was sufficient to recharge the EVs. More than 86% of weekday trips and 88% of weekend day trips would recharge in less than 3 hours.

Overnight charging will have minimal impact on the grid despite an increase in the overall electricity consumption. Overnight charging by the amount required to replenish daily commutes is easily coordinated and managed, similar to how heating of off-peak hot water systems are currently co*ordinate"

is anyone doing this tho? so far all thwe cars ive seen start charging as soon as you plug in the charger

And there lies more cost - those of us at the moment may well be paced to profit from developing systems.

Those buying in post implementation phase are going to start paying through the nose.

You’re positing “Watts up with that” - a notorious climate denial blog - as a credible source on this issue?

Sounds awfully like the crap that was being published about some street in Melbourne with Teslas that was pulling the grid down.

For the record, I saw the Teslas in Sandy Point recharging and the grid did not collapse.

I run a solar/battery UPS for my work. Which to use? Grid or solar power? I use which I need mostly solar to charge as much as possible then sit fully charged for a month for if the grid fails , it does fail once or twice a year. Scheduling is simple software not massive hardware needs so I assume it would be very easy. Batteries need a Battery Management System (BMS) for charging and distribution of power back for you. Only dopey ones have no scheduling ability even now.

One or two of the EVs ae advertising they can be used to time shift solar power from day to night already or as a back up power supply.

The later "back up" does require "islanding" which does require planning and a sparky "Islanding is the condition in which a distributed generator (DG) continues to power a location even though electrical grid power is no longer present. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered, and it may prevent automatic re-connection of devices."

Perhaps you should read more widely. I try to read both points of view and then make my own decisions.

Or do you believe Al Gore, Greta Thunberg, Michael Mann etc without reservation.

In this case the article quotes that a German Minister tabled this proposal and had to withdraw it . This appears to be a fact. if you have evidence to challenge that fact please publish it.

Interesting "Watts Up With That? is a blog promoting climate change denial that was created by Anthony Watts in 2006. The blog predominantly discusses climate issues with a focus on anthropogenic climate change, generally accommodating beliefs that are in opposition to the scientific consensus on climate change"

Never looked at it before "Greenland Ice Mass Loss Below Average In 2020" Perhaps it should be a another name like clap trap "There is no evidence whatsoever that melting will suddenly start to run away.
Mixes 'sort of true' if you distort the evidence they base their claims on.

If not "







Between September 2019 and August 2020, the rate of ice loss from the Greenland Ice Sheet was much lower (293 ± 66 billion metric tons), but still above the 2002–2020 average measured by GRACE. Average ice loss for Greenland over the full 18-year record was 268 ± 14 billion metric tons per year.Dec 8, 2020"

Loss of "28 trillion tonnes of ice in less than 30 years" is possibly closer to the truth.

Off topic sorry.

Companies such as Audi; BMW; Ford; Lexus; Mercedes; Porsche; Volkswagen and Volvo all have new models launching this year.

Then there are new names that may become household in years to come. Cupra; Polestar; Rivian and Lucid are brands either created from traditional manufacturers or new start-ups, but they all have new EVs to offer the market.

Sorry Phillip I was not having a go at you when posting a WIKKI opinion of a website. I do not think "Al Gore, Greta Thunberg, Michael Mann etc should be taken without reservation or proof"

Reading and reviewing is very important. Some of the articles on the site you mentioned are interesting to read. In investing I find reading opinions very opposite to my own very useful to temp over enthusiasm at times. Hydrogen might be an example or uranuim for a real basket case I am still holding on to.

Suspect some on both sides are a bit extreme the same as the LEFT/RIGHT. BLACK/WHITE no consideration for others views. Your views are very appreciated. Regards James
