The Our World in Data blog post, A sense of units and scale for electrical energy production and consumption has the graph here. It provides a comparison of the scale of different types of electricity production along with comparisons to consumption. For example the Three Gorges Dam is worth 270,000 MWh while the Hoover Dam provides 11,000 MWh. On the other hand the Alta onshore wind form generates 7,342 MWh. The post has a nice discussion of units as well as information about the types of electricity generation they highlight in the graphic.
