Slimmer omgaan met energie en materialen
De wereldbevolking is in de afgelopen eeuw exponentieel gegroeid, en daarmee ook onze behoefte aan energie en materialen. Willen we in de toekomst ook in welvaart leven, dan zullen we onze economie en consumptie radicaal anders moeten inrichten. Wetenschappelijk onderzoek laat zien hoe dat kan.

‘Toen ik het in 2010 had over de materialen voor een energietransitie, werd er nog net niet gelachen’
Om windturbines en elektrische auto’s te bouwen, hebben we tonnen magneten nodig. Momenteel importeren we die voornamelijk uit China, waardoor Europa voor de energietransitie erg afhankelijk is van deze grootmacht. Daar moet verandering in komen, aldus Industrieel ecoloog René Kleijn. In het project…
