The U.S. energy industry was licking its wounds when oil recovered to the $60 level in April. Now, with the price of a barrel back in the $40s, the industry mood is dark, with an outlook for lower oil prices well into next year, meaning more shelved projects, deeper cost cuts and tighter-than-expected funding.

Funding is the life blood of U.S. energy supply, as it provides cash flow for an industry that needs to make capital expenditures in order to make money. A cutback in funding could mean less drilling, which is bullish for the price of oil, but negative for companies seeking to generate cash flow.
