The speech was the second time in a week Romney focused a campaign stop on energy policy, looking to capitalize on unease over unseasonably high fuel prices. Last Thursday in costal Virginia, Romney blasted the administration's hesitation to authorize new licenses for offshore drilling. Wednesday in Colorado, Romney focused his remarks on domestic oil and natural gas production, saying the EPA should authorize hydraulic fracturing to reach new energy reserves and open new federal lands to oil companies.

"This is a recognition that finally has to come to the White House because it's come to the American people," Romney said.

Romney also lampooned the president's initiatives on green energy, highlighting companies that have struggled to repay federal investments or generate job growth.

"They should do more studying on Solyndra and less studying on drilling on the intercontinental shelf," Romney said, alluding to the solar energy company that went bankrupt last year, defaulting on its federally-backed loans.

Later Wednesday, Romney will campaign in Oklahoma City with Gov. Mary Fallin, where he is again expected to discuss energy issues.
