We debate the new book from Bill Gates titled “How to Avoid a Climate Disaster: The Solutions We Have and the Breakthroughs We Need.”
Can we significantly reduce carbon in the next 10 to 30 years? Is it worth the cost? How many technological breakthroughs do we need to do it? Has the Texas Blackout shown us that intermittent solar and wind energy are too unreliable and potentially deadly? Will we soon be eating substitute synthetic meat?
From the Guardian: Ever the technologist, Gates sets out a spreadsheet for getting rid of those 51bn tonnes of greenhouse gases and achieving net carbon zero emissions by 2050. We would need to use more renewables and fewer fossil fuels (which would account for roughly 27% of the reduction needed in emissions), and change how we manufacture our goods (31%), grow our food (18%), travel (16%), and keep our buildings warm or cool (6%).
Highlights:
· There is no real plan to get to net zero other than investing in R&D and hoping for major technological breakthroughs. We need more than a dozen new technologies that don’t exist today to get anywhere close to zero.
· Solar and wind have a huge upfront carbon footprint based on the increased need for concrete, cement, steel, glass and other materials.
· Solar and wind power are intermittent and this relates to the crisis in Texas. All the power sources failed but wind failed the most and the earliest.
