Energy is the amount of electricity a generator produces over a specific period of time. Many generators do not operate at their full capacity all the time. For instance, about 26% of New England''s system capacity is made up of coal- and oil-fired generators. But combined, they produced just 3% of the region''s electric energy in 2017.
