I think that the 60 gallons of oil corresponds to the oil in the gear box for a large wind turbine. Wind energy has a very small carbon footprint.

In observing that “every type of energy has consequences,” Department of Interior Secretary Ryan Zinke claimed the “carbon footprint on wind [energy] is significant.” In fact, wind power’s carbon footprint is among the smallest of any energy source.
Coal’s carbon footprint is almost 90 times larger than that of wind energy, and the footprint of natural gas is more than 40 times larger, according to the Department of Energy’s National Renewable Energy Laboratory.
To be more exact, wind energy produces around 11 grams of carbon dioxide per kilowatt-hour of electricity generated, Garvin A. Heath, a senior scientist at NREL, and colleagues concluded after reviewing the scientific literature. That’s compared with about 980 g CO2/kWh for coal and roughly 465 g CO2/kWh for natural gas, Heath found
