Approval for fracking in North Yorkshire has raised the prospect of the controversial technique being allowed at other sites and restarted an intense debate.
Councillors in North Yorkshire on Monday voted to allow fracking near the village of Kirby Misperton.
The decision, greeted by jeers, has been called a "victory for pragmatism" by those in favour.
It is the first application approved since 2011.
Fracking is a way of extracting oil or gas from rocks by pumping liquid into them at high pressure.
New licences for the technique, seen by the government as crucial for future energy needs, stalled since 2011 after tests on the Fylde coast, in Lancashire, were found to have been the probable cause of minor earthquakes in the area.
Other areas of concern for those opposed include fears that the technique can contaminate the water supply.
The application to drill was granted to the UK firm Third Energy to frack for shale gas at an existing drilling site using an existing two-mile deep well - called KM8 - drilled in 2013.
Chief executive Rasik Valand said the company now had a "huge responsibility" to deliver on its commitment "to undertake this operation safely and without impacting on the local environment."
Hundreds of protesters attended a meeting in Northallerton to voice anger at the project, which had been recommended for approval.
The council's planning committee voted seven to four in favour.
As it happened: Fracking decision meeting
A number of objections from people opposed to the plans were heard over the course of two days prior to the decision.
Supporters including landowners, farmers and Third Energy employees also had their say.

Industry body UK Onshore Oil and Gas said it was an important first step for frackers, an industry which attracts fierce local opposition whenever a site is chosen for fracking but which has strong government backing.
The Government has said it is going "all out for shale" to boost energy security and the economy.
Professor Paul Ekins, professor of resources and environmental policy at University College London, told BBC Radio 4's Today programme, the decision was a "political watershed".
He said there were still planning conditions that the company would have to comply with, so fracking at the site would not start immediately.
Opponents are exploring whether or not the move can be blocked.
Friends of the Earth called the decision a "travesty" and will see if the move can be challenged.
Greenpeace accused the government of having a "pro-fracking bias", which they said made the outcome inevitable.
Craig Bennett chief executive of Friends of the Earth told the Today programme: "In 2016 we should not be building new oil and gas structures, we should be moving away from oil and gas as fast as possible."
Ken Cronin chief executive of UK Onshore Oil and Gas said it was the right thing to move towards renewable energy but it could not happen overnight. He also said that whatever the type of energy the country attempted to produce there were local planning objectors: "The situation is that in the UK we have a problem whether it's wind or shale. Getting through the planning system involves a number of objectors."
