wind’

No you dont.

A smallish nuclear spill is about as dangerous as a truck of bananas.

There cannot be any big 'spills' and there never have been apart from Chernobyl, and that killed just 75 people. You are more likely to be killed by a wind turbine blade falling on your head.

I see you haven't a clue.

Final exit temp from a typical steam turbine is around 45°C-60°C

That's why cooling towers are used.

Latent heat of evaporation cools the last turbine exhaust, and then the atmosphere condenses the steam out so it runs back down the walls again. Obviously a handy river sea or lake is cheaper, but cooling towers work, and if they are less efficient in very hot weather, well demand is less, too.

I think that all conspiracy theories about Covid have been proved false. We have always known that politicians are incompetent, especially when it comes to anything to do with science.

I doubt if anyone here doubts that there is climate change. There may be some doubt that most of it is man made and even if it is that our current policy on green energy is sensible for a reliable supply or will actually make much difference.

What is likely is those on this group to question a lot of the green hype much of which is misleading or just loosely based on some truths. So much of it appears to be based on future technology that may, or may not, appear.

What is very likely to kill the green revolution is a lack of substantial energy price reductions. The general public hear on a daily basis that wind and solar electricity is cheap - if not free, and a substantial amount of our energy comes from these sources. If this doesn't result soon in cheaper bills then they will start disbelieving the hype and any other claimed benefits for renewable energy.

Personally I've always said that the green revolution was about saving the planet and not about saying the wallet. I also seriously question the wisdom of relying too much on wind and solar, especially now that we have real data for a number of years for a statistically representative high number of panels and wind turbines.

Devils advocate....

As a solar panel will not be CO2 neutral for at least three years, and a wind turbine or EV for much longer. Any mass adoption of these technologies in a short time is only going to add a lot more CO2 to the environment.

It's debatable how much CO2 a wind turbine will save when considering regular maintenance, especially when installed in remote areas.

As an example of possible increased CO2 usage, where I regularly visit which is a rural area with electricity delivered via overhead cables there are regular flights with two helicopters flying low monitoring the overhead lines. I'm assuming one carries a thermal camera. I've seen them land for the occupants to examine the state of the poles.

The oldest wind turbines have reached EoL and are needing replaced, so if they haven't contributed to a lowering by now, will they ever?

So you’ve not noticed any increase in extreme weather events, exactly as predicted by climatologists?

Tim

Ah, you believe that the UK is the only country on the planet?

Of course our country’s contribution to global CO2 production is relatively small but that doesn’t mean that we shouldn’t do our part.

Tim

Have there been a greater number or it that every weather event in every country is now reported instantly on the 24 hour a day media? We have just had a hot June so it must be climate warming!

I’m sure Spaniards and Texans will take great comfort from your confidence that extreme weather events aren’t more frequent.

Tim

Extreme flash floods in Texas are common. The difference this time was the number of associated deaths.

If ’doing our part’ means living in mud huts and eating turnips and beets, I’ll think you’ll find that won’t be a vote winner.

What we are actually doing is exporting production, and with it we are exporting the resultant CO2 release to countries that don’t really care about it. The problem being that there’s only one atmosphere, so all that feel-good that believers enjoy is largely illusory.

Only a few weeks ago there was a weather event that we were told was the worst one since 1952.

What the believers failed to grasp is that 1952 was before ‘climate change’ got going.

So three years to cancel out its CO2 production costs and then 17+ years of replacing fossil fuels with clean energy. That seems a rapid win.

An EV has larger up-front emissions than an ICE vehicle, but much lower emissions from there on. They can equalise in as little as 18 months, but then its a win for the EV for the rest of its life.

Even a big push and an emissions spike will be cancelled out in only a short period - and that big push would still be spread out over years, if not decades, so the spike will be pretty low.

A small sum of emissions compared to those saved by mass switching to electricity.

My problem is not with the shift to electricity, but the high capital costs to homeowners and the costs of adding intermittent supplies, that still need backup for the cold, dark, still winters.

Just spend the money on nuclear and have reliable, 24 hour a day, 365 days a year, electricity. We even have a number of ex-nuclear sites that already have nuclear licences and existing grid infrastructure.

The waste heat can gasify volatile liquids (such as LPG) to drive expanders to produce electricity, allowing siting anywhere. The energy extracted cools the LPG, allowing it to re-liquify and circulate again.

It's basically the same as heating water to drive steam turbines, but works with a much lower level of heat.

Do you (or anyone) happen to have a reasonable assessment of the environmental impact of renewables? I've read a few articles but end up more confused than when I start . . .

And to add to it all, methane is being positioned as the 'new CO2' - higher impact short term:

That's why the Dutch farmers were up in arms, govt buying up cattle farms in order to shut them down, to cut down on burps and farts.

It’s surely just part of a wider plan to get people to eat less meat.

Apart from the elites, of course, who just love to dine on Kobe steaks and swill fine wines, while flying at 35000ft.

In which case, let dairy cattle burp less while they're producing the milk

1. The climate has always changed. It is not clear that its really much warmer than it was as the ways of measuring this are highly suspect,.
2. It is now irrelevant as to whether its man made or not. Renewable energy has failed to make the slightest difference.
3. We are running out of *cheap* fossil fuel.
4. Ultimately we therefore have to embrace nuclear power or revert to mediaeval life styles.
