Recent visitors to Aberdaron may have been surprised to see an enormous drill in the National Trust car park. Rather than drilling for oil it is actually to extract a much more environmentally friendly form of energy - ground source heat to supply the self catering apartments at Henfaes. The deepest borehole dug so far is 210 meters in depth. Once the boreholes are all finished the lengths will add up to 800 metres in total to extract heat energy from deep in the ground where there is always a constant temperature.

| You can just make out the drill shaft rapidly spinning. |
 |
| The drill is an impressive sight from ground level. |
 |
| One of the steel pipes being winched into place to presumably be fed down the hole. |
 |
| This is probably the pipework which will carry down cold water to be warmed up deep below the ground and returned to the surface. |
 |
| It looks like there are lots more pipes to be sent down. |
