Wind/solar produced 29% last year, so a bit more

 

3rd quarter , when its usually windy ?

 

It must be a happy house hold you live in, everything you comment on has a negative, pessimistic view. Do you have permanent rain cloud over your head?

Half full glass, as opposed to half empty, would serve you better

 

dont get me wrong , blanket the country with solar as far as im concerned

But dont lets get mugged by statistics

 

I'm all for using more renewable energy, but you have to acknowledge that renewable's are incredibly inconsistent. Solar in only useful when the sun shines. Wind doesn't work if there is no wind or, funnily enough, if there is too much wind. Tidal is pretty consistent and predictable, but there are two still periods per day, at least one of which will always fall during peak times. The only renewable we can control is bio/compost which of course still creates CO2 (and worse) emissions. We can of course increase hydro storage to store the inconsistent renewable energy to be released at peak times. I'd definitely be in favour of building a huge dam in the Thames estuary and flooding up to the Thames valley, would also solve a lot more problems than just the energy crisis

But yes, thumbs up for more renewable's, but also be realistic that non renewable's are equally important to create the required energy stability. At least until we can come up with a consistent renewable solution.

On a side note, its great to see one of SN lead Brexiteers posting an article about how Brexit is threatening the renewable energy growth in the UK When did you become a liberal and start reading the Guardian

 

here you go - it might dispel a few myths





have faith in humanities ability to solve problems (the trick of course is to recognise the problem)

 

I read most papers from the Independent to the Mail. I'm not swayed by either end of any argument. I make my own mind up on things

 

Here's a possible.

Isnt this same thing ? ( did some work for the owner few months ago )

Crap economy today, electric seats and steering wheel took its toll
102mpg

​​​​​​More favourable conditions .this afternoon same journey 147 mpg


This my XC90 hybrid btw

 

 

No you can buy the car outright or lease the whole car

 

Youll never actual get 147 of course , well only for the 1st 27 miles !

its as an appalling con in the same way every celeb mus have a prius , somewhere , along with rest of the fleet

 

Depends on the manufacturer. Some insist you buy, others insist you lease and others give you the option. If you buy, you may take a hit on the resale value. Leasing the bateery is probably the long term better option. If you can't lease the battery, the lease the car is the best option imho.

 

Most of my journey s are less than 25 miles, so the equivalent for the those journeys is 100+ mpg

On the rare occasions I go further the car averages 38-48mpg. The car is 2.5 yrs old and only done less than 5 journey s .of 100+ miles

 

mpg is a completely useless figure for comparrison for anything other than cars on the same fuel. Its like omparing apples to chocolate teapots!

A gallon of petrol has a completely different energy density than diesel, LPG, Hydrogen and I'm really not sure about the energy density of a gallon of electricity.

Comparing diesel to petrol for example, diesel cars have a lower mpg figure, but diesel has a higher energy density than petrol. Petrol cars burn the fuel more efficiently though, so they can convert more of the stored energy into drive. On the balance, diesel is still more efficient than petrol, but not by as much as the mpg figures would imply.

To give a better comparrison, you really need to consider how much energy is required to travel a given distance for a given fuel type and vehicle. i.e. compare apples to apples!

For electric vehicles, you should also consider the energy loss from charging the vehicle. i.e. the amount of energy you have drawn from the grid and not the amount of energy the car used from the battery. Also, as has been said before, you don't know where the electricity came from. If its nice clean wind energy, then great, but if its from coal or gas, then you're almost certainly better off with oil based products from an efficiency point of view. Don't get me started on the amount of water you need to consume to extract the lithium from salt plains!

Another thing to consider for the future, hydrogen has the best energy density of all available vehicle energy sources Sod electric vehicles, convert to hydrogen

 

Its to give a comparison against what the majority of vehicles are currently use as fuel. When electric is the main power source for cars,, folk will talk about Kw used per mile

 

Trouble being - nobody knows where that kw came from !

 

Given that the whole mining. refining, transporting, manufacturing process for the metals used for making these lithium ion batteries is one of the most polluting processes in the world, hybrids are really the worst of both worlds ecologically. Not only do they encourage pollution in the lithium manufacturing process but they also contribute to the pollution associated to the drilling, refining and transporting of crude oil as hybrids still use fossil fuels like a conventional car. Sure it looks great for the consumer at end of this chain they can quote nice green figures for their motor, but all it's done is shift the pollution elsewhere where lithium and colbolt mining and disposal of the associated waste is largely unregulated, unlike the oil industry.

Its not in Andys back yard though ...

 

Electric is obviously the future, however lithium ion obviously isn't, the mining is devastating.

Hydrogen will probably be the mass fuel in the long term coupled with more efficient solar for partial charging as you go, plus other small bits.

 

can you buy a used electric car that has a battery lease and not take out the lease and take your chances with battery reliability? Looking at a 1 year old Renault Zoe but the battery lease puts me off. If I could ignore the lease option I could be tempted .

 

I don't know about Renault, Nissan have 8 years 100k miles warranty on their battery packs

 

You would have to ask Renault if they would sell the battery as they are the owners. My guess is they wouldn't as it's their business model to lease the batteries. If you intend to keep the car for 5 years or more, then I wouldn't risk buying them, leading is probably the best long term option!

Will we be able to dictate air pollution quality in deepest India eg , now we're out of the euros

( where its proper filthy for your health)

 

Why does that bother you when the damage to people and children and the environmental and health impact is far worse for those who mine the cobalt and lithium in your cars? Just because you like to be smug about mpg and low emissions where you live, doesn't mean your car doesn't pollute elsewhere.

 

The hypocrisy, says him typing away on his laptop/phone containing a lithium battery

 

Our first 10,000 miles in the Leaf has cost us £213 in electric

equivalent petrol car doing say 30mpg would of cost £1500
