Trends in Electricity Generation


The table below shows trends in electricity generation nationally over the last decade. The rise in usage of natural gas is the clearest trend. It also appears that this rise has eliminated rate increases (I am not sure that this is true for Ohio). As noted in the first footnote, wind and solar are still minor factors.
