Energy prices have been rising fast. But not enough to derail the economic recovery. Not yet anyway.

Over the last month, crude oil prices have risen over 4% and are approaching $100 a barrel. Analysts think they'll soon trade in the triple digits. Gasoline futures are up even more, rising 8% over the last 30 days. At the pump, drivers are now paying 14 cents more a gallon than they were in mid December.

The only outlier is natural gas, which is used to heat homes, among other things. Natural gas prices have fluctuated widely based on the weather, and have fallen about 4% this month as the cold snap gripping much of the country was expected to ease.
