Limieten aan grondstoffen beperken nu onze groei

Given our experience, we are hard-wired to believe that growth is bound to continue, but we have reached the limits of our planet.

Tot voor kort waren we de rijkste mensen ooit. Sinds het einde van de 20ste eeuw, daalde het inkomen van meer dan 90% van alle huishoudens, ondanks vele pogingen om economische groei te stimuleren. Ook het toekomstperspectief voor jonge mensen is steeds negatiever geworden. Velen kunnen geen passende baan vinden, en hebben geen perspectief op eigen huis en langdurige carriere.

Voor het eerst in 250 jaar zijn energie en grondstoffen de beperkende factoren aan het worden voor nog meer groei. Meer extractie is in toenemende mate moeilijker. Dit is moeilijk te bevatten voor ons, aangezien onze hersensen het beste werken wanneer we het verleden extrapoleren. Als dat niet lukt, zijn we in verwarring.

After 10 years of mostly scientific work on understanding our human ecosystem, energy&stuff is IIER 's first public outreach project. Given the very negative societal dynamics observed around the world, with hate and blame on the rise, we consider it relevant to instill a sense of reality into the discussion, hopefully supporting a different and more constructive dialogue moving forward.

Cobb-Douglas, a formula and a principle with limits
The drivers of most economic planning, labor , capital and their productivity, are at the core of the concept described by the Cobb-Douglas production function. Unfortunately, this "unlimited" view has hard limits in energy and resource availability that didn't matter during the 20th century.

Back to the future of economics, or: when economists were right
Economic theory wasn't always oblivious of natural resources, quite the contrary. Before the 20th century, most models included land avaialbility and productivity, a marker for the ability to convert sunlight into relevant outputs. Only during the 20th century, with the abundant availability of stored sunlight, this factor disappeared from theoretical models. Now, as we move away from easy fossil fuels, we need to go back to Adam Smith and his peers.

Productivity, its components, and its limits
Labor and capital productivity growth was seen as the key driver of growth during the past 250 years. However, we didn't get more productive based on our ingenuity alone, the key drivers were increased energy and resource use with low energy and resource productivity.
