We're told solar and wind future

But when wind is not blowing and sun not shining?

Batteries!

Yet

The world uses 51GWh/minute and has 64GWh of battery storage: enough for 1m:15s

2030: 10m:24s

After that, need 100% backup, mostly fossil fuels

Batteries won't save the US

The US has batteries able to supply 3:24 of average electricity consumption now and about 10 minutes in 2030

Image
Batteries won't save Asia

Asia has batteries able to supply just 31 seconds of average electricity consumption now and about 10 minutes in 2030

Image
Batteries won't save Europe

Europe has batteries able to supply a little more than 1 minute of average electricity consumption now and about 12 minutes in 2030

Image
Lots of people suggesting we can fix this

Yes, but it makes 𝗿𝗲𝗻𝗲𝘄𝗮𝗯𝗹𝗲𝘀 𝗰𝗼𝘀𝘁𝗹𝗶𝗲𝗿 because we need to pay for backup

More realistic solar costs are 4-7x higher

from cheap but very unreliable
to very expensive (and only less unreliable)

lazard.com/perspective/le… Image
Most people don't appreciate that

most renewables (RE) to date are only possible because they are backed up by modern fossil (MF) fuel tech

(such as Combined Heat and Power and Integrated Gasification Combined Cycle)

People suggest that "it is always windy somewhere", but

1) not sufficient throughput between regions

2) European 2021 wind drought showed us it can be less windy almost everywhere

depleting other sources of energy and end up costing us a fortune

How much are 3-10 minutes of electricity storage?

Not much

Every year in Germany, there are more than 5 days (7,320 minutes) with almost no wind, and every 10 years almost 8 days without wind (11,160minutes)

iopscience.iop.org/article/10.108… Image
Perhaps not surprisingly, most people like power 24/7

Yet, most climate policy seems to be driven by crossing our fingers:

just build lots of wind and solar
& hope to fix intermittency later

But not enough batteries

And leads to much higher prices

The first slide says 10.6 minutes, but it should be 10.4 minutes or 10m:24s Image

New study: Climate change saves 282,000 babies

Higher temperatures mean more heat, and more babies dying from heat

but it also means less cold, and many more babies not dying from cold

In total, higher temps saved 282,251 babies in 29 poorer countries from 2000-19

Did you read that anywhere?

nature.com/articles/s4146…Image
As we have come to expect from studies of heat and cold, they use unequal scales, which makes heat and cold look about the same

— they're not, as you can see on the right


nature.com/articles/s4146…

Image
The study is very explicit in pointing out that the change in extra heat deaths and fewer cold deaths is caused by climate change

EU climate policy has enormous costs

Industry electricity prices have increased 70% in real terms since 2000

EU industries now pay 2.7x the electricity price in the US (and 1.9x in China)

EU households now pay 2x US electricity price (and 3.3x China)

EU climate policy causes high electricity costs

Consequently, EU can afford much less electricity per person

In this century, the EU has managed to get access to almost as much electricity per person as the US got in 1968

EU climate policy has enormous costs

Electricity prices for industry have increased 78% in real terms since 1978

EU industries now pay 2.5x the electricity price in the US (and 1.9x in China)

EU households pay 2x US electricity price (and 3.3x China)

Outrageously misleading climate scare from the UN

Today, 85% more old people die from heat

What they don't tell you:

There are now 86% more old people

Fake news doesn't just come from foreign enemies

Friday, WHO claimed that 175,000 Europeans died from extreme heat

I pointed out that was untrue, almost 4x exaggerated

Saturday morning, WHO admitted this in the smallest possible way — they simply changed their website (and address) and had some online publications delete "extreme"

But, of course, by then the story had already made its intended impact across the world

WHO believes "Climate change is the greatest threat to global health in the 21st century" — which is just laughable and one of the reasons it was caught off-guard by Covid

This belief colors the 'findings' of WHO. In their Friday statement, the WHO Europe director explicitly worries about the "climate crisis" and expressed his support for climate action costing $1,000s of trillions (1.5oC target), so he obviously would like a dramatic and large number to make it around the world

Summary: WHO told us extreme heat kills 175K+, a number they've now admitted is almost 4x exaggerated. And they don't tell you that cold deaths at 657K are almost 4x bigger than all heat deaths. This is not informing you well

Journalists have to realize that when e.g. WHO says something, it also needs to be fact-checked

Friday claim:

Saturday update:

The actual problem put in context:

WHO wrongly claimed that 175,000 Europeans die from extreme heat every year

This scary but wrong story got all the headlines

When called out, WHO acknowledged it by simply changing their website (and some online publications)

— but by then, all the scary stories had already had their impact

Friday claim:

This is what WHO should tell you (because it is true):

Moderate cold is the biggest killer in Europe, followed by moderate heat, extreme cold, and only lastly by the smallest killer, extreme heat

But that doesn't fit the narrative

Another environmental scare debunked:

Acid rain killing all forests was the main environmental scare in the 1980s

A new half-century study shows acid rain doesn't kill trees

— actually, trees grow more with acid rain!

sciencedirect.com/science/articl…Image
Acid rain scare in the 1980s delivered full-on panic

No more so than in Germany, where papers claimed "the forest is dying," called it an "ecological Hiroshima" and claimed ‘‘the dying of the forests will have a greater impact on our country than World War II’’

All falseImage
The 1980s Acid Rain scare we know now was mostly false

New study: acid rain actually makes trees grow faster

Yet, a majority of Germans in 1985 believed "all forests will be dead by 2000" because of acid rain

We were misled

Today, the Great Barrier Reef is better than ever

But 12 years ago, we were told about the "Great Reef Catastrophe"

and how the reef would be almost gone today

Moral of the story: Don't always believe the scare stories

Refs in🧵
Here is the 2012 article telling us about the terrible state of the Great Barrier Reef

and about how it will almost halve again by 2022 to 5-10%
