Correcting Anti-Renewable Energy Propaganda | CleanTechnica
Anti-renewable propagandists need to talk about imaginary high costs of renewables, especially because one of their preferred ways of generating electricity — nuclear power — turns out to be incredibly expensive.
Renewable energy gets cheaper each year, nuclear power gets more expensive each year — how come they still adamantly claim that renewables are not a cost-effective way of decarbonizing?
The answer, of course, is that the studies are flawed. Taking a look at these studies shows that several patterns can be observed in many of these studies. Among these flaws are ridiculous overestimates of storage requirements, overestimates of grid expansion needs, and the insistence on uneconomical strategies of storing electricity, such as insisting on batteries to store several weeks worth of grid electricity consumption.
In order to understand how these studies are flawed, it’s essential to understand how a renewable energy grid actually works, how energy storage works, and what costs you can expect. After that, I will describe the flaws in some of these studies and recalculate a more realistic scenario, especially more realistic cost projections.
