Serious flaws have been found in a decade’s worth of studies about the best way to reduce greenhouse gas emissions and stabilize the climate.
sciencedaily – The findings, from the University of Michigan, are released as world leaders at COP21 attempt to negotiate the globe’s first internationally binding climate agreement.
The U-M researchers have found that most economic analysis of carbon capture and storage, or CCS, technology for coal-fired power plants severely underestimates the technique’s costs and overestimates its energy efficiency. CCS involves sucking carbon out of coal-fired power plants’ flue gases, compressing it and then injecting it deep underground.
The new analysis puts the cost of reducing carbon emissions with CCS-equipped coal plants higher than any previous study — and most importantly, higher than wind and comparable to solar power. It’s the first study to confront the so-called ‘energy loop’ inherent in the CCS process. Tiếp tục đọc “Carbon capture analyst: ‘Coal should stay in the ground’”
The cars in question include the Passat, Jetta, Beetle, Golf, and Audi A3.
