Last year,Citi produced a powerful study of the costs and benefits of shifting the energy system toward low-carbon technologies. Unchecked climate change, Citi said, could cost the world $72 trillion by the middle of the century. But the big surprise in Citi’s report was the cost of building the low-carbon economy: the world can spend $2 trillion less in total on energy infrastructure and ongoing fuel costs than it would in the business-as-usual scenario. So we save $2 trillion and avoid losing up to $72 trillion in economic activity.

 

Holding global warming to 2-degrees Celsius will require keeping huge quantities of fossil fuels in the ground. These so-called “stranded assets,” sitting on petro-company balance sheets, are essentially worthless. And thus those companies are massively overvalued.

“We are like tenant farmers chopping down the fence around our house for fuel when we should be using nature’s inexhaustible sources of energy - sun, wind and tide. I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.”
