Asked what would most enhance U.S. energy security, participants overwhelmingly said opening up more acreage for domestic drilling was the best option. In particular, 43 percent said the Arctic National Wildlife Refuge should be opened for drilling. Another 28 percent said more investment in renewable energy sources such as biodiesel would enhance U.S. energy security the most.

However, even though many of the executives support further investment in renewable energy sources, the majority still don't view renewables as a serious near-term solution to the energy supply equation.

In last year's survey, 60 percent of 553 petroleum industry executives said large-scale production of renewable fuels was not a near-term possibility, at least not in the next couple of years.

In the most-recent survey, 54 percent gave the same response, though 2015 was the target date.
