TRANSCRIPT:

The Green New Deal is a policy proposal where we use massive investment to build a zero-carbon renewable energy infrastructure.　インフラ、基盤、仕組み

 

But:

 

1) Renewables cannot make renewables (“renewables aren’t renewable”!!): making wind turbines, solar panels and batteries is very energy-intensive (mining, transport, manufacture, installation, maintenance, disposal in 30 years) – we can’t do this without the energy density of fossil fuels.

 

2) Only 19% of global energy consumption is electricity, the other 81% is liquid fuel, we can’t replace liquid fuel with renewables because both batteries and hydrogen take more energy to make, store and transport than they provide.

 

3) There are many social justice problems with our industrial civilization: mining destroys the environments of poor countries so that rich countries can live in luxury.

 

4) Global warming is only one part of our problem of ecological overshoot: we are using the earth’s resources faster than those resources regenerate (e.g. deforestation), so eventually those resources are going to run out. When they do, our civilization is going to crash. 地球の自然資源の消費は再生産量より大きい。利子のたとえ

 

Conclusion:

The Green New Deal is technically impossible, and ignores all the other ecological​ problems anyway.

The only logical conclusion is that “material life after fossil fuels will closely resemble life before fossil fuels.” : “biomass (especially wood), simple mechanical wind and water generation, passive solar, and animal and human labor”, which will mean “major reductions in energy supply”

Hey listeners what do you think?

Your turn to vent! Would you like some tea?

1. Do you agree that the only way forward is a simple low energy society?

2. Do you see any way forward on this politically?
