The newly passed Republican tax bill includes measures to open Alaska's Arctic National Wildlife Refuge to drilling. It's been a long-held goal for domestic energy advocates — but those resources might not be worth digging into right away.
The Energy Information Administration estimates oil in the refuge represents almost 12 percent of total U.S. reserves. Tapping it would be in line with the Trump administration's America-first energy strategy and with producers who want access to reliable resources.
"The reality is that world oil demand is rising," Alaska Sen. Lisa Murkowski said. "We know we're going to need this oil in the years ahead."
But right now, the world has plenty of cheap oil. Financial analysts say new drilling doesn't make much economic sense.
And environmental groups say they're ready to sue to stop new projects, especially if they don't do a thorough job of meeting strict federal regulations on drilling.
Even those who stand to profit from Alaska's oil expect it could take decades before drilling begins.
