Having gotten on board last year, imajerbear summed up the opportunity:

Energy is one of the long term places to be. I feel that we are 15 to 20 years out from alt energy making significant inroads on oil and gas usage. Barring a global meltdown, oil can only go up. ... Too many people not enough energy.

Energy Select Sector SPDR, in particular, sports a low expense ratio of 0.20%. That's cheaper than that of other energy ETFs like iShares S&P Global Energy (0.48%) and SPDR S&P Oil & Gas Exploration & Production (0.35%).

CAPS member StavrosW elaborates on the bull case:

Nowhere do the simple rules of supply & demand present themselves more evidently than in energy. Energy is driven by oil right now, which we all know is of a very limited quantity. This is a no-loss situation if you are a long term player. ... [W]ith a ever growing global community, increasing demands on energy, no real alternative as of yet, and a very limited supply, this one is a winner.
