According to conventional wisdom, there can't be a significant rise in inflation without a corresponding, and usually preceding, jump in energy prices.
In fact, the correlation between energy prices and inflation has become almost a mantra among some market pundits.
Unfortunately, the reality is somewhat different than what's portrayed by talking heads in thirty- second sound bites.
As with most complicated problems, the answer just isn't that simple.
While the energy sector stretches from hydrocarbons, through alternatives, to the renewed interest in solar, wind, geothermal and biofuels, it is the dominant force in the sector that tends to drive the markets.
That means crude oil and natural gas.
