Just a few years ago, a small village in North Yorkshire became a magnet for protesters who were opposing hydraulic fracturing for gas - also known as fracking.
Now, the organiser of those protests works for the same company he opposed, but it has tapped into a greener energy source.
On this episode of ClimateCast, Tom Heap heads to North Yorkshire to meet workers at the firm which has swapped fracking for geothermal heat.
He speaks to the staff who have turned away from fossil fuels, and also to former protesters about their victory and the green energy solution that's on their doorstep.
