Energy prices are among the most volatile of all commodities.
This is clearly illustrated by looking at price movements on the futures market. The principal drivers behind this volatility are supply and demand fundamentals, which include the weather, storage activities, and the perception of market conditions. They are watched closely and constantly evaluated by market players as to their adequacy in view of expected weather conditions. Events that cause sharp stock draws and bring stocks down below normal levels often result in price surges. Exposure to price volatility in the commodity market varies widely by type of consumer.
