Energy source wonders

An energy source wonder is an energy resource whose magnitude and use by society is unsurpassed by any other, such as Ghawar, the world's largest oil field. Energy source wonders can be renewable, as in the case of Denmark's offshore wind energy, or nonrenewable, as in the case of the uranium deposit at McArthur River, Canada. Great energy sources generate great wealth for their owners, and often are controversial because of their social and environmental impacts.
