I’m still wondering where all the mythical power is coming from to power all these EV’s. We’re about an order of magnitude short at the moment if everyone had one - and do t just quote me ‘roof top solar and batteries’ because that ain’t going to do it.
The amount of energy we use each day from petrol and diesel is staggering. If you take that away from the equation that power has to come from somewhere. It certainly isn’t there at the moment or even being planned for.
Even if the source could produce enough power for everyone to have an EV, the infrastructure couldn't cope with the draw.

Some say we will just have to put up with what is around,but i know one thing,businesses wont.
Jaguar came out beating their chests saying they would be all EV from 2025,about a year ago,and have recently released two new Diesel models,which seems a bit strange.
In other places I hear they have a few ideas[bighmmm] We have the most of what that idea uses but do not use it except in Medical, research an possibly a underwater thing I used to play with [biggrin]Quote:

Back to school for me
Energy density is the amount of energy that can be stored in a given system, substance, or region of space.[2][3] Energy density can be measured in energy per volume or per mass. The higher the energy density of a system or material, the greater the amount of energy it has stored
Fuel Type Reaction Type Energy Density
(MJ/kg)Typical uses Wood Chemical 16 Space heating, Cooking Coal Chemical 24 Power plants, Electricity generation Ethanol Chemical 26.8 Gasoline mixture, Alcohol, Chemical products Biodiesel Chemical 38 [8] automotive engine Crude oil Chemical 44 Refinery, Petroleum products Diesel Chemical 45 Diesel engines Gasoline Chemical 46 Gasoline engines Natural gas Chemical 55 Household heating, Electricity generation Uranium-235 Nuclear 3 900 000 Nuclear reactor
electricity generation
I think I see the one I meant[biggrin] Lots of zeros makes it fairly clear not that I will b driving anything powered by it unless its used to create electricity or Hydrogen of course.
Above 34170000000 liters * energy density suggest about 1571820000000mj to replaced
10 grams time????

I agree we need nuclear but even if there was an appetite for it, we’re looking at 15 to 20 years to bring a reactor on line. That’s not the only problem - as mentioned, how is that going to be transmitted to where it’s needed? If you look at Melbournes grid at the moment it’s pretty much at capacity - it would take billions - with a B - to bring in the amount of power needed to charge a city of EV’s. You can barely get an upgrade to a sub now anywhere and if you can it costs huge money for the developer.
Working in the power industry for my entire career I just can’t see how it can be done - nor do any of the Engineers I discuss this with. It’s an investment that everyone wants and needs but no one will cough up for.
In the UK the demand on energy caused by the current small take up of BEV vehicles has resulted home car chargers now only being able to be used in off peak periods
The drawing is Flawed. Using figures from the chart 10g Uranium is more likely going to be equivalent to 454.000 litres of oil, and 10,000 tons of coal..

There are also reports of public charging points being load shedded as well.Quote:

We spend about $30b a year importing oil, which makes us vulnerable to overseas threats, so becoming more self-sufficient will help national security.
We're not short of energy, we just have to be smarter about using it.
BTW I see Ford is about to release EV Rangers and Transits and Mitsubishi an EV Triton, so the trend is happening.
If we move to Euro6 or better vehicle emission standards that will stimulate a flood of EVs, rather than us being a dumping ground for vehicles with dirty exhausts, as at present.
Long haul trucks will remain diesel for a while, but there are EV big trucks coming from Volvo, Ford and others. Battery charging depots along major routes will see trucks roll in and forklifts used to pull out the used batteries and slide in charged replacements. I read about a plan for battery depots in Brisbane, Coffs, Taree and Sydney, for example.
It's happening.
