No Climate Protection without Climate Justice; No Climate Justice without Degrowth
Shortly before the most crucial UN climate change conference after the failure of Copenhagen, it seems that the international climate-movement is finally getting its act together: resistance against fossil fuel extraction is gaining ground and a rising global movement is putting pressure on institutions to divest their money from fossil fuels to finance renewables instead. Green jobs in the renewable energy sector have been a success story and it is broadly accepted that we need to keep 80% of the known fossil fuel reserves in the ground if we want to prevent runaway climate change. Last year, more than 400 000 people flooded the streets of New York City in the largest climate march in history and, as the global development of renewable energy increases in scale and efficiency, people are starting to believe in a transition away from fossil fuel dependency.
This is of course good news, and nobody concerned about climate change would seriously doubt that the global transition towards renewable energy is an absolute necessity. However, much as right-wing conservatives, mostly in the US, deny anthropogenic climate change, the majority of the climate movement tends to deny an equally important issue: that renewables are unable to maintain our Western growth-based consumer lifestyles on a global level.
“Renewable” does not equal “unlimited”
The limitations and environmental impacts of renewables are being discussed in breadth and depth elsewhere; suffice to say here that e.g. wind mills and solar panels are very energy-intensive in production – and intensive in other natural resources too, such as metals, minerals and rare earths. Windmills for example require lots of concrete which is a highly CO2 intensive industry. Solar photovoltaic systems use on average 23-59 kg of aluminium per kW – the aluminium sector being another CO2 intensive industry.
