SubscriberI’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.

If you don't like trucks, stop buying stuff.

I have been saying that for ages,i recon there are going to be a few,if not many backflips.
For commercial use,utes,vans,there is nothing around in the world, with a half decent range,yet alone something anywhere near as convenient as what we have now.
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.
Very Very Lucky!
In other places I hear they have a few ideasWe 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
A really interesting article on 30 years of misinformation was in the paper today. Oil oil and oil some say a very very good PR person so the proof by insiders suggested
One not fact check place said "Australia consumed a total of 34,170 megalitres of fuel in 2018" that about 34170000000 liters
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 meantLots 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????

SubscriberI 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.
There is a plan to spend $20b to upgrade the energy transmission network with 3 upgraded corridors in Qld, one in NSW (Snowy Hydro 2.0) and one in Victoria, so more renewable sources can be connected.
The states are also installing big batteries at a rapid rate, some to replace worn-out coal power stations, to store surplus power locally and release it when needed.
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.
