Weird headline in our village newspaper: "No nuclear power plant". Turns out that Utrecht's provincial council has asked all municipalities whether they'd like to host a new nuclear power plant in their area...
Sensible answer from our alderman: "No. First of all, we think nuclear energy is a matter that would benefit from some national coordination. But we don't have an industrial zone or cooling water either."
Adding "We haven't done specific research into this issue, but we do know from a recent opinion poll that 28% of our population is 'to some extent' open towards this form of energy" :)
Turns out this funny approach was the result of an initiative in the provincial council in September 2020, by VVD, CDA, FvD (far right populist party), 50plus (elderly people), with some support from PvdA. rtvutrecht.nl/nieuws/2097924…

There are around 270 million passenger cars in the EU+UK.
Assuming they drive around 12,000 km/year and use around 800 liters of gasoline/diesel for that, their final energy demand is around 8 MWh/year each, and 2,000 TWh in total. That’s around 1/6 of total final energy demand.
If you’d replace all of them by electric cars, those would use 2-2.4 MWh/year each, so around 600 TWh in total.

This would reduce EU+UK final energy demand by over 10% (from 12,000 to 10,600 TWh), and increase electricity demand by 20% (from 3,000 to 3,600 TWh).
So just this passenger car replacement would drive up the share of electricity in EU+UK final energy demand from 25% (3000/12000) to 34% (3600/10600).

OK, that was back of the envelope. Would be nice to redo with more precise numbers, but should be in the ballpark.

The shrinking electricity use of Dutch households, thanks to efficiency. By 2018, the annual consumption per household had already decreased by 15%, from its peak in 2012. A year ago, the PBL agency estimated it would drop by another 10% in 2019 and 2020.
cbs.nl/-/media/_pdf/2… Image
Latest estimate from @statistiekcbs for 2019: 2,730 kWh per household. Higher than the PBL estimate, but still 16% lower than the peak (3,250 kWh in 2011, according to CBS).
The 2020 consumption will probably have increased due to corona (more at home), but the trend is clear. Image
So 20% of Dutch households can buy an electric car and charge it at home (I assume 2,500 kWh/year), and average household consumption here will still not be higher than it was in 2011-2012.
Long live LED lighting ;! (and other efficiency improvements).

Who’d have thought?!
The Netherlands led Europe in new wind capacity installed in 2020: +2 GW (1.5 GW offshore, 0.5 GW), ahead of Germany, Norway, Spain, and France!
Also, this was 13% of the EU+UK+Turkey total. Admittedly in not a great year overall.
H/t @VeraBrenzel / @Vision23 Image
Wind power capacity additions in Europe (incl. Turkey) have stagnated around 12-17 GW/year for 9 years in a row now... Image
.. but @WindEurope sees it moving into the 20 GW/year range from this year onwards (‘realistic expectations’). Image

On energy efficiency in EU buildings, you often hear that the renovation rate needs to go up from 1% per year to 3% per year. But what does that mean? The EC's Renovation Wave paper provides some clarity.
eur-lex.europa.eu/resource.html?…
So all the measures taken to improve building energy efficiency (better glazing here, some roof insulation there, etc.) reduces the energy consumption of the total building stock by around 1% per year.
The idea on the way forward is often to take big steps, combining a deep renovation (>60% energy demand reduction) with a zero-emission source of heating. But such deep renovations are now carried out only in 0.2% of the building stock per year.

Cost overruns and delays building up for UK’s Hinkley Point C nuclear power station. Total cost now estimated at £23 billion in 2015 pounds, that’s around £26.6 billion in today’s money = €30.1 billion, or €9,400 per kW. ft.com/content/fbc43d…
Hinkley Point C’s completion date has been pushed back by another 6 months, to mid-2026, that’s 5.5 years from now.

In October 2013, UK govt expected the plant to be completed in 2023. Construction started in December 2018.
“EDF will turn on its first nuclear plant in Britain before Christmas 2017 because it will be the right time,” Vincent de Rivaz, then its UK chief executive, promised in 2007. “It is the moment of the power crunch. Without it the lights will go out.”

Renewable power supplied 38% of all EU electricity in 2020, surpassing fossil electricity for the first time!
This was driven by the continued growth of wind and solar, now supplying 20% of all EU electricity. The dip in electricity demand due to the corona crisis (4% for the year as a whole) had a modest effect.
The growth of renewable electricity was a major factor in the decline of coal-fired power generation in the EU, to only 13% of the total in 2020.
This development was helped by the higher EU-ETS CO2 price (now €34 = $41 per tonne).
