We're told solar and wind future

But when wind is not blowing and sun not shining?

Batteries!

Yet

Asia uses 25GWh/minute and has 13GWh of battery storage: enough for just 31 seconds

2030: 9m:55s

After that, need 100% backup, mostly fossil fuels

woodmac.com/news/opinion/t…
This is similar to what we see in Europe, with batteries able to supply a little more than 1 minute of average electricity consumption now and about 12 minutes in 2030

Lots of people commented suggesting we can fix this

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

Solar costs go up 4-7x, from being some of the cheapest electricity to very expensive

lazard.com/perspective/le…
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

ft.com/content/d53b58…
How much is a couple of minutes of electricity storage?

Not much

Every year in Germany, there are more than 5 days (120hr/7,320 minutes) with almost no wind, and every 10 years almost 8 days without wind (186hr/11,160minutes)

Two days ago, Spain lost 55% of its power, most from solar

Perception: Everyone wants to blame anything but renewables

Reality: With renewables, the grid gets vulnerable (missing inertia, mainly from fossil fuels) so we need more costly renewable management

So Reuters deceptively tells us, "don't blame renewables," blame "management of renewables"

reuters.com/business/energ…Image
"By continuously reducing inertia, Spain’s policymakers engineered a vulnerability."

"Spain’s electrical grid was operating with very little margin for error, a risky game that the Spanish government has been playing more aggressively each year since energy-transitionist ideologues took power two decades ago."

The myth that the green energy transition is inevitable and will make cheap electricity for everyone is one of the most dangerous self-delusions of the global elite

My piece for Sunday Telegraph

archive.ph/EufH0Image
Globally, fossil fuels supply 81% today (2022)

only marginally down from 81.2% in 2000

On current trends, fossil fuels are not on track to end in 2050
but in 4-9 centuries
iea.org/data-and-stati…Image
You are told that solar and wind are cheap

But cramming in more solar and wind just makes power more and more costly

because solar and wind are worthless when not sunny and windy

Spanish floods are tragic — as they are everywhere

But remember flood deaths down dramatically

Globally, floods now kill 5,400/year, down from 400,000/year in 1930s

Deaths from European floods down 7-fold to less than 100 per year today

nature.com/articles/s4146…Image
Despite breathless climate reporting,

not only are European floods causing fewer deaths (tweet above) but

Losses from floods in Europe are declining, not increasing

nature.com/articles/s4146…Image
Death from flooding declining (2nd row)

not only for rich countries but for poor countries

Deaths declining for almost all extreme weather for rich and poor

for flood, flash flood, coastal flood, cold and wind

and for all extreme weather

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…

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)

iea.org/data-and-stati…Image
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

I write about this and many other heat scares from the UN in today's WSJ
