Renewables such as wind and solar are sure to produce some variables in the outlook, but Alerian President and CEO Kenny Feng says the energy mix will remain largely unchanged over the next 20 years.

With that understanding, Feng reminded oil and gas executives in attendance at the inaugural Midstream Finance conference on Oct. 23 of the importance of remaining capital-efficient in their business practices.

“This is a growth business,” said Feng, who kicked off the conference as the keynote speaker. “Growing the distributions of cash other than the rate of inflation is a bad use of that capital. Leverage targets need to come down.”
