Enron was an infamous energy company in the US.

Under deregulation, energy companies like Enron manipulated power supply, drove up prices and, forced rolling blackouts. Prior to deregulation, electricity was sold at a regulated price reflecting the cost of generating the power plus a reasonable profit for the power producer. Under deregulation, the market was supposed to take care of itself and, freed from government regulation, save consumers money, but it did the opposite.

Through deregulation, it allowed allowed middlemen to buy and sell electricity like a commodity in the free market. The attempt to create a market for the trading of this essential service developed out of the greed of power companies like Enron to profit off of. When a service as vital to society as electricity is left in the hands of unregulated companies like Enron, it becomes the subject of those companies' greed.
