Bust the renewable energy myths to achieve an honest mix of energy supply
I believe in a simple premise: our current way of life is not sustainable. Because I believe that if we do not effectively change the way we live we face an existential threat, I also believe that we need to start being more serious about the claims we make and the solutions we propose.
Eventually humans domesticated grains and began simple subsistence farming, and the ratio of energy invested to what we got back grew to 1:3. Over time we discovered better ways to harness energy, such as windmills and water mills, and this level increased modestly, until we discovered coal: with a gargantuan 1:130 or more ERoEI, the industrial age was born.
To completely replace fossil fuels, one estimate in the Manhattan Institute’s publications shows we need to expand renewable energy production 90-fold over two decades, whereas the best we achieved was 10-fold in five decades for the fossil fuel industry. And to store two days’ worth of electricity capacity for the US national grid alone would require more than 1,000 years of battery production at the Tesla Gigafactory. It isn’t feasible.
Changing our current farming techniques could lead to us sequestering more carbon than we produce, and would produce healthier food
