Wholesale electricity prices, along with with oil, gasoline and natural gas prices, have fallen significantly since the summer 2008 peaks. Whether the decline in wholesale electricity is -50% or -77% seems less important than the fact that the decline is significant, and energy price declines for oil, gasoline, natural gas and electricity will create significant savings (billions of dollars) for consumers and businesses in the coming months.

The 10-day moving average (-61.3% decline from the July peak), the 20-day moving average (-57.1% decline from the peak) and the 30-day moving average (-51.1% from the peak). In all cases, the current wholesale electricity price of $47.38/MWh is close to a four-year low, and will likely continue to fall.

Nows the time to jump back into energy. With energy companies feeling the pinch of this global downturn, these stocks are at bargain prices. Energy needs are on the rise which means more customers to service and more revenue. Since the deregulation debacle, energy companies have taken the necessary steps to ensure power to its customers. Investors looking for long-term growth of their money should buy these stocks while they're at their 3-year low. There is growth on the horizon in a market full of downturns as the consumption of power is not decreasing but rather increasing. This is one of the best times to buy this stock.
