Green, ethical, energy issues in the news

I'm starting to giggle in a strange and unsettling way when I see articles like this. It's sort of great and crazee all at the same time.

I'm old enough to remember when 5MW's was considered big (and Trump was unlikely to get elected).

I did notice this though in the Guardian article

“The 5% VAT rate will still be allowed for housing associations and buyers who are over the age of 60 or receive certain benefits.”

That’s good news for oldies like me but I doubt many people on benefits will be able to afford a battery system.

Still more petrol pumps though....

What actually counts is throughput. How many cars an hour can be served by all the charging points versus how many cars an hour can be served by all the petrol stations. It would be interesting to compare those numbers.

Including home and work charging locations?

In two weeks time we shall have owned our EV for exactly one year. In that time it's been charged at home apart from on four occasions. Twice via a households three pin plug where we'd stayed for a day or two and twice at motorway services about halfway through five hour journeys when comfort and coffee breaks were very welcome.
Just our experience from the first years ownership.


Oh, with combined running and fuel costs averaging 1.1pence/mile with zero emissions I can only compare the benefits in health and financial terms to those when I gave up smoking in 1974. Of course others may choose to disagree.:rotfl:

Hi

... And that's the main point that is consistently overlooked in such conversations.

A 200-250 mile range between charges results in many vehicles covering average mileage through to well above average hardly ever using fast chargers or even destination ones .... that takes a huge load off the public 'refueling' infrastructure which likely compensates for much of the additional time connected to the 'pump' thus reducing the current perception of the number of public charging points that will eventually be required.

The link provided in one of yesterday's posts effectively proved that high mileage runs could be performed in EVs when a fast charger network is in place .... the real question revolves around how many on this thread have ever needed to drive for 10 hours and managed to average 60mph, including rest breaks & refuelling? ... even if there's a couple of drivers in the car!

An average motorist travels around 20 miles per day, so in an EV likely consumes around 4kWh, so around 90 minutes of charging for each day's motoring even with a 10A plug in 'granny cable', however most would likely charge once per week on a 7kW dedicated point, so around 4 hours (4kWh*7days/7kW) over the weekend or overnight when they're asleep ...

Can't remember what the source was but I read/heard that approaching 90% of
all EV mileage is currently covered using home or workplace charging, so that gives a base guideline to work from for sizing a fast charge network ....

Only crossing France on the peage, once south of the clag around Paris! Once a year..

On the way back, going for the ferry and with potentially dodgy winter weather we pootle back on a less direct combination of peage and RN over two days.

That's ringing a bell with me too. Possibly different source, but I'm sure there was an interview on Fully Charged quite a few years ago with one of the companies that installs chargers and home chargers. They know who you are, so to speak, when you charge, and I recall a 90% or 95% figure for slow charging ...... I think? Or perhaps it was more general, that 90% or so of the leccy they supply goes out via their home/slow chargers v's fast chargers ..... something like that.

People who can charge at home on a driveway are just more likely to buy an EV, so as far as im concerned its total rubbish stat looking into the future.
