Energies is the term used for a type of commodity society uses as energy, be it for heating, transportation, cooking, or otherwise. The category includes commodities like oil, natural gas, heating oil, and gasoline. Among these, the market for oil is by far the biggest.
Trading in energies is popular among forex traders because it is a different way to trade developments in the world economy than what forex represents. However, many forex pairs are still related to energy prices, with the currencies of oil-producing countries like Canada for example often being sensitive to the price of oil. Because of the very large and liquid markets that exists for energies, most forex brokers offer CFDs on at least a few of these commodities.
