Energy Yield per m2

Energy yield per m2 for biomass, onshore wind, offshore wind, Dutch PV-solar and Sahara PV-solar resp.

Using land to harvest energy in countries like the Netherlands is a waste, better use it for food or timber production and outsource energy production to other places like the in desert or at sea. The best place to harvest renewable energy is the desert, which is good news for countries in North-Africa or Arabia.

For overpopulated countries like the Netherlands, use all available roof space for solar and the North Sea for wind, but be skeptical about onshore wind and solar parks. Award that source of income to Africa (so they can buy our products). Britain and Germany, same story.

Energy from Biomass only makes sense as a waste product from food or timber production.

Lightyear One Solar Car First Deliveries This Summer

The Lightyear One solar car will be able to deliver a daily average driven distance of 34 km for free, “out of thin air”, at least during the usually modestly sunny Dutch Summer.

Who Will Be the Cheapest Future Hydrogen Producers?

China will be the cheapest place to produce green hydrogen in the long term, followed by Chile, Morocco, Colombia and Australia, in an “optimistic” scenario, according to analysis from the International Renewable Energy Agency (Irena).

Chinese producers could be delivering green hydrogen at a levelised cost (LCOH) of just over $0.65 per kg by 2050, with Chile only marginally behind.

Even in the most pessimistic cost scenario, China would be producing green H2 at an LCOH of about $1.10/kg by mid-century, with Colombia at around $1.15/kg and Australia and Chile around $1.20/kg.

The Right for Building an OWF is Going to Cost You


It began in Denmark, now Germany is next: if a developer wants to build an offshore wind farm (OWF), he’ll have to pay for this privilege (read: gold mine) and this is not surprising at all, in the light of the development of electricity prices.

Take The Netherlands. In early 2021, 1 kWh would cost a private household about 22 cent. Today, that’s about 67 cent! At the same time, the cost of an OWF hasn’t changed much, so, wind energy has become extremely competitive overnight (mostly due to dumb western maneuvering in the case of Ukraine and the subsequent immanent end of globalization, but I digress).

RWE paid the Danish government EUR 375 million for building and exploiting the 900 MW Thor wind farm. The current raised German offshore wind targets are: 30 GW by 2030, 40 GW by 2035, and at least 70 GW by 2045, compared to 8 GW today. If the recent Danish RWE deal would be scaled to this ambition, the German government would rake in 23 billion until 2045. Expect the real number to be much higher.

Carver S+

The new Carver edition, the S+, increased its maximum speed from ca. 45 to 80 kmh and is electric. 20 kmh extra and Carver is a serious car replacement. The time of driving in a 5-seater sedan, with average occupancy rate of 1.25, is now really over.

Carver S+: €17.078 / £14,490
Vehicle Category: L5e-P
Top Speed: 80 km/h – 49 MPH
Battery Pack: 7.1 kWh Samsung SDI NCM
Range: 100 km – 60 Miles
Charge Time: 3hrs 45min

Announced Esbjerg North Sea 2030 Wind Plans Not That New

Green = planned for 2030, on the left what is installed now.

Martien Visser confirms:

NL, BE, DE and DK proudly announced yesterday that they will build or have built 65 GW offshore wind in 2030 “to replace … Russian oil, coal and gas”.

However, these are plans that were known well before the war. What is new is that there will be better cooperation.

Water Usage per Popular Agricultural Produce

Did you know that it takes more than 15 times as much water to grow a kilo of avocados, as compared to a kilo of bananas? And more than 5 times as much soil? That gives you a different perspective on that keto diet of yours, now does it?

Popular Dutch Holiday Destinations by Emissions

Vertically, the share of emission-free energy consumption

In the extreme unlikely case that you want to link your European holiday destination to the emission status of the country, based on primary energy use, as a sort of reward, here is the data you would need.

Listed are Dutch holiday destinations in declining popularity, from left to right. For real CO2-zelots, the Netherlands itself is a no-go area, so Dutchies, start your SUV and off you go to Norway!

P.S.: if oil and gas exports would be included, Norway would crash to the bottom of the ranking.

Steep Increase Value PV-Generated Electricity 2022

The sharp increase of the value of pv-generated electricity in the Netherlands (and elsewhere) is to a large extent due to increased electricity prices.

[] – Martien Visser

Back-of-an-envelope calculation. My private 6 panel solar installation from 2015 did cost 3000,- all in. Based on an electricity price of 21 cent/kWh, payback time was 8.5 years.

The Dutch consumer organization Consumentenbond reports:

The price of a kWh is very high at the moment. It shot up at the end of 2021. In March 2022, we measured an average of €0.67 per kWh. Many consumers are still on a current energy contract at lower prices. These are somewhere between €0.24 per kWh (price level July 2021) and the current, high rate. It is very uncertain how long the electricity price will remain at the current very high level.

[] – Wat kost een kilowattuur (kWh) elektriciteit?

At an electricity price of 67 cent/kWh AND a decreased price for solar panels, as compared to 2015, that new payback time for a solar installation will be more in the order of two years.

Consider: the price of 400 Watt solar panel is about 180,- Annual yield in the Netherlands: 400 x 0.85 = 340 kWh per panel. At an electricity price of 67 cents, that represents a financial value of 228,- The panel pays itself back within a year! In 2015, the total cost of my installation was composed of 1500,- for the panels and 1500,- for the inverter, mounting, cabling or 50-50. Hence, the estimate that a new solar installation will earn itself back within 2 years, under the new fossil-based price regime. I’m writing this at a time when Germany has announced it will support an anti-Russian oil boycott (under grave international and media pressure; who is the US waging war against? Russia? Germany? Both?). If they go after a gas boycott as well, 67 cent/kWh could be an underestimate. I’m tempted to buy 10 additional solar for mounting against a garden fence NOW and avoid the rush and probable scarcity in a few months time, when the new price regime will assert itself. These panels deliver a suboptimal yearly yield, but they do deliver more electricity during the winter.
