Klimaatfeiten.net
Klimaatfeiten.net (lit. “Climate Facts”) is a Dutch research and information website covering greenhouse gases, climate science and energy systems. The site operates as a technical research project aimed at presenting the climate and energy dossier in a factual and accessible way, with particular attention to model uncertainty, cost comparisons and the technical realities of the energy transition.
Background
The website was initiated by Ir. Wouter de Heij, based in Wageningen through Food4Innovations. De Heij approaches the climate and energy dossier from a technical-analytical perspective, emphasising quantitative reasoning and scrutiny of widely held assumptions in the public debate.
The site publishes articles on and by contributors including Remco de Boer (chemical-technical engineer, PhD University of Amsterdam 2015, host of the podcast Studio Energie) and references the work of energy scholar Václav Smil.
Topics
Klimaatfeiten.net covers the following themes:
- Climate science and modelling — operation and limitations of climate models, suitability for policy use, temperature data and the hockey-stick graph
- Energy costs — Levelised Cost of Energy (LCOE), Value-Adjusted LCOE (VALCOE), price trends in renewable electricity, home batteries and nuclear power
- Renewable energy — capacity factors of wind and solar, peak versus actual output, grid power and grid stability
- Nuclear energy — investment costs per megawatt, thorium reactors, comparison with wind and solar
- Hydrogen — applications, efficiency, comparison with heat pumps
- Biomass — wood combustion as an energy source: benefits and drawbacks
- Methane and livestock — the role of agricultural methane in the climate debate
- Energy policy — European electricity costs, the Dutch energy transition, a proposed energy policy vision
