Anyone who thinks Wind is going to solve our issues has not been watching Gridwatch in the last month (April) see gridwatch.co.uk/Wind
Forget summer : demand is low. In Apri; wind output was low due to long periods of still air.. and solar was affected by long periods of damp cloudy weather. This Year Daily averages chart says it all. Wind often was at under 10% of demand - in summer it can be 50%.
And remember, on peak days, much WInd output is wasted - the Grid cabling has not been upgraded and cannot cope.. We pay suppliers anyway. (!)
I note the Tesla ad for the new EV truck : talk of $200k pa savings per truck in running costs: $0.07KWH vs diesel/petrol $.40.
Would not work in UK: electricity costs are far too high.
Black outs in 2029

The long term answer to intermittent energy (eg: wind) is storage. EV batteries can provide some of this.
A more immediate answer is that the UK needs a clear energy strategy embedding energy supply from a number of sources.
Nuclear can provide a base load.
Wind and solar can provide green energy, albeit intermittent. Tidal (eg: Severn barrage) could be intermittent but predictable.
For the foreseeable future (20-30 years) gas can provide capacity to balance any shortfall in both nuclear and other green energy. This requires almost no investment in new capacity - only maintenance of existing.
It may eventually be worth building new gas generation capacity simply to act as a back up to intermittent wind. Wind has a high capital cost and low operating costs. Gas is the opposite - comparatively low capital costs and high running costs.
The main risk to electricity supply is a lack of a strategy and plan, not the variability of wind power.

Large areas of the world are being dug up to satisfy increasing demand for battery material for EVs deemed essential to purify the atmosphere. Relying on even more stationary batteries to cope with peaks of electricity demand will not help.

The areas being dug up for materials used specifically in EV's are frankly tiny by comparison to what else humans mine from the planet.
94% of EVERYTHING mined from the ground is iron ore (3.2 billion tons in 2019). Materials needed specifically for EV batteries makes up a tiny percentage of that remaining 6%, way down below bauxite, manganese, chromium, lead, nickel, zinc, titanium, zircon, magnesium, strontium, etc, etc.
And lets not forget about the 15+ billion tons (in 2021) of oil taken from the ground (to be burned once).
That isn't to say other solutions shouldn't be sought for EV batteries (and they are), but people who jump up and down about the impact caused by mining for the specific materials needed for EV batteries really ought to factor in some context.

No, we get different and more extreme weather types - it won't always be warmer.

I've read that the instances of 'extreme weather events' like hurricanes have actually decreased over the past decades. And those 'experts' have now gone quite over the 'great standstill' over 'rising' global temperatures, which now haven't risen for over a decade.
Most problems we've experienced come because of over population - building large numbers of homes on flood plains or on prime farmland / countryside areas, not dredging rivers, not maintaining or upgrading (to take into account all the extra usage) drains, sewerage and water treatment systems, or electricity, water and gas distribution networks.

The temperature is still rising.

Plenty of link on the net to show that is not true. Here is one:
Global warming hiatus - Wikipedia
Global temperatures have been increasing for decades now.
And it's not true about the hurricanes either:

The observed data overrides the narrative.
"In summary, it is premature to conclude with high confidence that increasing atmospheric greenhouse gas concentrations from human activities have had a detectable impact on Atlantic basin hurricane activity, although increasing greenhouse gases are strongly linked to global warming.

<< ... people who jump up and down about the impact caused by mining for the specific materials needed for EV batteries really ought to factor in some context. >>
Point taken, but that wasn't the point I was trying to make. I should have suggested that increasing demand further for the minerals needed for large batteries would not help. Big holes have been dug for centuries. We as a nation are more than happy that, having dug up and sold much of our own mineral deposits (largely overseas) that our recent demands are being met where we can't see it. Nimby again ?

Sure, but that assumes battery tech doesn't change from what it currently is.
One of the big Chinese car manufacturers, BYD, is going to be launching a model with a sodium ion battery imminently.
I also learned the other day from a YT video that Australian scientists have discovered an enzyme in a common soil bacterium which converts air to electricity. How or if this could be harnessed on the kind of scale needed remains to be seen, but it should give hope. It is also ample proof that while ICE technology has gone pretty much as far as it can, there is still much to discover and learn when it comes to batteries and electricity.

You don't need to apologise. Unlike you I am not a scientist in any way shape or form, so cannot really comment on whether or not this is possible.
However, here is a link to the relevant article from the website of Monarsh University in Melbourne.

I have heard about this being found in volcanos, not taken any notice though, but coming from different sources maybe something in it. you never know!

Thanks for the link. The first few sentences clarify the situation : the enzyme doesn't convert 'air' into electricity, it converts the very small amount of atmospheric hydrogen. So I doubt it can contribute much to the running of any vehicle. :-)

Hydrogen is found in great quantities on Earth combined with other elements, such as in water and hydrocarbons, but it is barely present in our atmosphere, which contains just 0.00005%.
Hydrogen already combined with other elements would require energy input to extract it - possibly more than the energy in the hydrogen!
Not likely to be a transport solution!!

There is very little atmospheric hydrogen, partly because it combines easily (as said here) but also because of its very low mass, earth's gravity is not enough to stop it drifting off into space, where most 'cosmic' hydrogen exists.

That's disappointing. I thought you would be able to tow a trailer of soil with a couple of electrodes inserted.

It's odd that people give such consideration where the electricity is coming from and how the grid can support this. What is the sustainability, and were any ocelots harmed in the creation of my new Tesla etc.
All very laudable I'm sure.
But do purchasers of new petrol cars spend any time worrying about peak oil theory and how the lesser spotted marmosets might be affected, by clinate flummery ? I'd wager not.
Clearly a double standard.
|
All very laudable I'm sure. Clearly a double standard.
Probably true, but that is back to my earlier point - too many people like doing too much travelling in the long term (petrol vehicles have only been around for about 130 years and recoverable oil reserves are well on the way to exhaustion already). Any kind of mass travel requires energy in some form, and EVs are only a way to avoid polluting metropolitan areas with exhaust. Petroleum is solar energy stored over millions of years, and that process is being rapidly reversed. The amount we could capture via solar panels will not go far to meet the demand. Nuclear ? to drive all the EVs - I doubt it.

Transport is a major part of UK energy consumption (approx 30%) - a shift to EV is significant but not game changing.
France generates 68% of electricity from nuclear - it would be entirely possible for the UK to meet all energy needs now and in the future from nuclear. It would be strategically risky being reliant on only one energy source so not a sensible idea.
Solar power makes significant demands upon land use so may not be capable of effectively unlimited capacity. It can make a worthwhile contribution.
But wind power over the last year has provided 30% of electricity output. A cursory look at any wind farm map suggests that wind power alone could comfortably meet total UK demand - although variability and storage is an issue.

I have a very tenuous theory that Elon Musk is so obsessed with space so that he can start launching nuclear waste up there and therefore make nuclear power plants sustainable.
In the meantime, I should also point out that (notwithstanding night time and transmission losses...) it would be possible to provide the entire world's electricity needs by covering a little over 1% of the Sahara in solar panels.

The only problem with the Sahara is political instability. Look what happened with Russia and gas. But yes I get the point. We could cover every supermarket carpark with panels which at least would have the side effect of providing shelter from the rain.
As for Musk, I could believe your theory.

I used to think that the use of arable land was a waste for solar panels. But some of that land is poor quality, from the over use of chemical fertilsers and no rotation of the land between crops and animals. Driven by previous subsidies, there was no incentive for farmers to continue doing that, to the detriment of the soil. So at least the land is rested, and solar panels can be removed later.

I doubt if that would be feasible, given most if not all such large scale schemes would need the full lifetime of the panels at the very least to justify the expense of building it, and especially the upgrades of local links to the existing power network.
Old style crop rotation - including a year for 'fallow' used to work just fine. As I've said on other posts, there's loads of rooftop spaces available to not need ANY solar farms on arable or other countryside land. Building owners just need a gentle push with appropriate incentives where it helps those who cannot afford the outlay but would benefit from being a net energy supplier or near to.

The current wheeze with arable land is to sell it to developers who have to deliver 'nitrate neutrality'. Fertilisers contain high levels of nitrates and phosphates that get into water ways causing algae, which kills of wildlife. To stop it from getting worse, developers need to show that what they're doing doesn't increase nutrient run off. This is largely impossible, so the solution is to buy arable land, take it out of farming and just leave it. That offsets any increase in nutrients from the new development.
Large scale arable farming in this country is at an end.

In that case we need to think of more ways to generate income to pay for importing even more food than we already do. Let's hope the wizards in the city can keep their eyes on the ball a bit longer ?

Isn't that the leftists and Establishment reason for importing more people? Unfortunately it has the big side effect of compound that very problem, amongst many, many others.
Which is why we should be doing exactly the opposite - more self-reliance by being as self-sufficient on fuel, food and jobs. Odd how it wasn't the case from the late 90s onwards, when, as someone put it, 'something happened'.

That might be the case if we didn't have a reliable source of fuel or that the tech wasn't itself proven. I wasn't aware that either is the case, but diversifying energy production methods is still worthwhile. Nuclear is, after all, a base load technology, unlike wind, solar and tidal.
Solar power makes significant demands upon land use so may not be capable of effectively unlimited capacity. It can make a worthwhile contribution.
Only because the wallies in charge in Whitehall and for planning at local/regional level seem to be pushing for solar farms rather than actively encouraging owners of large footprint buildings (or any reasonable home owner) from utilising their roofs for PV arrays to locally generate enough electricity to make a decent contribution to the national load most of the time and to take pressure off regional and national grid networks (rebalancing / dealing with power cuts).
But wind power over the last year has provided 30% of electricity output. A cursory look at any wind farm map suggests that wind power alone could comfortably meet total UK demand - although variability and storage is an issue.
Wind power may have on average made a 30% contribution, but as I'm sure you're well aware, that contribution varies enormously over each day and from week to week, because the wind is highly variable - too much or too little means that the turbines are out of action and thus the base load MUST be there to cope with that shortfall.
Unfortunately, all the other 'green' technologies are also variable, and thus cannot be relied upon at peak times, especially in winter when the demand is highest, and even more so if the foolish switchover to electric only heating with no stored backup for the vast majority is forced through.

Solar panels on commercial properties has not taken off either due to the cost or more likely most commercial properties are not owned but leased. Private houses are not jumping on board with solar panels/Storage batteries due to the cost and payback time of some 8-10 years. I expect the landowners giving over fields to solar are on a nice little earner at the consumers expense probably hidden in the ever mysterious and increasing standing charges. It will not be long before all the Carbon capture nonsense is included in the SC. There are different views as ever on the merits of CC, I suppose when the trees start dying they will admit to the folly.
