More and more governments are requiring utilities to use more and more renewable energy, sometimes even directing them to not use some (such as hydro) and instead use others (such as wind). The goal is to usually to reduce emissions of carbon dioxide.
Why, then, isn't that the requirement? With wind energy, for example, its variability and intermittency cuts into its ability to reduce emissions, since conventional plants have to keep working -- even when not producing electricity -- to balance it.
