I don't understand the focus on how many windmills it takes to replace one coal plant. It's not like there's some limit to how many you can build. If the costs are comparable, that's what matters, no?
- plorg 12y agoAt a certain level it actually does matter. The sustainability of a power resource is measured in many ways, even if CO_2 emissions is the most widely touted. Measures like water use, construction cost/emissions, and land use are significant. The number of windmills being built _does_ have an upper bound, dictated by some combination of land requirement and material availability. Of late, for example, the desire for high-output synchronous turbines has been held back by the limited availability of the rare earth magnets that make them just so effective.
