While it is correct that, aside from hydro (the potential of which is low but of high quality) and wind (which provides low-quality power), modern renewables continue to be significantly more expensive, economic limits are ultimately a lesser constraint, as they can be overcome with political will and special efForts. In fact, most energy technology debates completely disregard associated socio-political limits. In pluralistic democracies, the “not-in-my-backyard” (NIMBY) attitude is a powerful factor.
