About us

We answer questions like: "If everybody switched to electric cars, how many solar plants would have to be built?". The ETM is used by governments, companies and teachers to evaluate strategies dealing with events like high fuel prices, diminishing gas reserves and disruptive technologies.

Quintel develops the Energy Transition Model and is a Dutch (grown up) startup, with an office in the centre of Amsterdam. Our team gets the work done during office hours, so that we can enjoy our evenings, with the occasional after-work drinks.
