30 December: wildfire triggers evacuations in Colorado
This from Superior, Colorado, a NW suburb of Denver.
And yes, climate change is a factor here:
The Four Wildfire Seasons.
This from a police car in Superior, NW Denver, Colorado.
By 5 pm local time, 580 homes had burned in Superior, and the Marshall Fire was still 'vigorously spreading'.
So far this year, nearby Boulder received 1 inch of snow (2.5 cm). The average for Oct-Dec is 25 inches (63 cm).
This from Boulder-based climate scientist Daniel Swain:

1,000 homes lost in Colorado's winter wildfire:
Long interview with climate scientist and wildfire specialist @Weather_West, who lives in nearby Boulder. How the fire tore through suburbs not thought to be vulnerable.
By @dwallacewells, via @moi_wins nymag.com/intelligencer/…
Including this on the wildfire climate connection: "It’s not like climate change is causing things to spontaneously ignite, but what it is doing is changing the character of wildfires. It’s expanding the window of what’s possible. ..
.. It’s expanding wildfire season. It’s increasing the upper end of how intense fires can become — how hot they burn, how fast they move."

Now we'll finally have our new government in the Netherlands (ETA 10 January), with a Minister for Climate and Energy from the @D66 party, I'm rereading the Climate & Energy part of the coalition agreement (kabinetsformatie2021.nl/binaries/kabin…)
Thread.
"We strive for the #ParisAgreement goal of max. 1.5°C warming". Good!

"We will raise the 2030 emission reduction goal from -49% to -55%. That's a firm commitment, and to make sure we achieve it, we'll aim our policies at -60% by 2030." Smart thing to do.
"We will also aim for -70% by 2035 and -80% by 2040. For that, we will make preparations to introduce road pricing and to build nuclear power plants."
Road pricing is long overdue, imo.

Now starting: Webinar on scaling up biomethane in Europe. With an impressive line-up of companies across the value chain, and participation of European Commissioner for Energy @KadriSimson
Supported by my colleague Daan Peters. Image
@KadriSimson You can still join, I think:
gasforclimate2050.eu/news-item/regi… Image
.@KadriSimson: In the medium and long term, we'll need to replace unmitigated natural gas and reduce methane emissions. Biomethane can play an important role here. With the second part of our #Fitfor55 package, due mid-December, we will promote biomethane production and use. Image

If I were in the government of an EU member state exposed to natural gas scarcity and very high energy prices, I'd use the momentum to put in place a massive energy efficiency drive, with short-, medium-, and long-term elements. Never waste a good crisis.
So far, the deer-in-the-headlight approach seems to be the more popular one, unfortunately.
Such a program would address all sectors: industry, large buildings, homes, trucks, passenger cars, shipping, and aviation. Quick wins would be combined with structural measures taking a bit more time. Long term commitments would form the basis for a whole new industry.

When I heard about plans for a series of new nuclear plants in France (first one ready around 2035), I remembered a similar announcement around 2005. Found it now! Image
By now, we were supposed to see one 1,600 MW nuclear power plant to be completed each year. The final decision was to be based on 3 years of experience with Flamanville 3, to be completed in 2012.
That article was published in December 2007, at the start of construction of Flamanville 3. The planned construction time was 4.5 years, but it still hasn't been completed 14 years later. web.archive.org/web/2014101402…

Current extremely high natural gas price in the Netherlands drives boom in anything that lowers consumption: hybrid heat pumps, insulation works, DIY materials. The right response! nos.nl/l/2402036
The best part of reducing your gas demand in times of scarcity is that every m³ saves reduces the price of the remaining m³, by cooling the market.
Somehow, you'd expect govt to be more vocal on the importance of energy conservation now, especially after just announcing a €3 billion handout to compensate everyone for the high energy prices.

Watching a webinar on the Dutch hydrogen backbone: Hyway27. Govt budget 2022 has funding for it. streamxpert.nl/hyway27webinar… Image
Modeled hydrogen flows in 2030 over the backbone infrastructure in the Netherlands, with the planned 3-4 GW of electrolyzer capacity, in PJ/year.
10 PJ = 2.8 TWh = 8,000 tonnes of hydrogen. Image
The idea is to use existing gas pipelines, becoming available as the Groningen gas field has to ramp down production.
The repurposing costs are estimated at just €0.4 million per km (cleaning, preparing, valve replacement) vs over €3 million for a new pipeline. Image
