How effective is light on the circadian rhythm of humans? Use the CS.

Posted by Marcel van der Steen in Explanation No Comments »

day_and_night-800pxThe circadian rhythm of humans is of importance for us; a.o, it takes care of our recovery. This rhythm can be influenced by the usage of light. The level of influence can be calculated by using a method developed by the Lighting Research Center (LRC), that uses the Circadian Stimulus value.

This is how Big Oil will die

Posted by Seth Miller in Transport No Comments »

7 SistersIt’s 2025, and 800,000 tons of used high strength steel is coming up for auction.
The steel made up the Keystone XL pipeline, finally completed in 2019, two years after the project launched with great fanfare after approval by the Trump administration. The pipeline was built at a cost of about $7 billion, bringing oil from the Canadian tar sands to the US, with a pit stop in the town of Baker, Montana, to pick up US crude from the Bakken formation. At its peak, it carried over 500,000 barrels a day for processing at refineries in Texas and Louisiana.

The Compact Flicker Degree (CFD) parameter, a measure for the flickering of lamps

Posted by Marcel van der Steen in Explanation, Led lights No Comments »

CFD_article_teaserThe light coming from (LED) lights can flicker. This effect is measured by OliNo for years already. The parameters given say something about the intensity variations and the frequency, but do not give a verdict. However Peter Erwin, aka Der Lichtpeter, has developed a parameter, called the Compact Flicker Degree (CFD), that analyses the flickering of lamps over a wide spectrum of frequencies and results in a value evaluating the flickering. Also it gives a color result like a traffic light. This article explains the parameter.

How Three Brand-New Power Plants in the Netherlands Are at Risk Already of Becoming Stranded Assets

Posted by Jeroen van Agt in Unsustainable No Comments »

kolencentrale-engie-rotterdamCoal-fired power generation is vulnerable everywhere to increasingly ambitious initiatives to cut carbon emissions.

This is acutely evident today in the Netherlands, where a recent court ruling and a parliamentary motion supporting tougher actions to avert climate change represent a growing trend.

This report assesses the impact of national pressures and beyond on the value of three new coal-fired power plants put into service in 2015 by the German energy companies RWE and Uniper, and the French energy company Engie.

More broadly, we note the implications from these examples for the business case for new-build coal power in Europe and further afield.

CO2 as solution for heating, not as a problem

Posted by Tinus de Vreugd in Energy saving No Comments »

CO2 HeatpumpR744 is the refrigerant name of Carbon Dioxide (CO2), and is a natural gas which is all around us. In fact, we cannot live without Carbon Dioxide! As with anything, adding too much CO2 to our environment, while the demand of the natural use from nature, is rapidly decreasing by cutting down forests, also for the use of fire wood and fuel pellets, is becoming rapidly a problem.

On electric adventure to Norway

Posted by Harm Otten in Transport No Comments »

Zoe rainbow Denmark[Klik hier voor de Nederlandse versie]
Two years ago it was the first time I went to Switzerland with my 100% electric Renault Zoe. 900km one way was a real challenge because back then there were no fast chargers. It made me happy if there was a semi-fast charger (22kW) on the route. This way I could not drive more than 350km per day. The next year there were some fast chargers and it was possible to make an entire tour of almost 2400km through Switzerland.
This year I set the bar higher, and the outward journey is already 2000km! Now I will mostly use fast chargers, and cover 550km per day. Seven different charge cards or phone Apps have been arranged. Hopefully they all will work, because I wasn’t able to test most of them. Furthermore, I will not use ferries on this trip, but drive entirely over bridges in Denmark and Sweden to Geiranger (Norway), where among other things I will attend the 20th anniversary of the Norwegian electric car association.
