- Winterdale Cheesemakers in the U.K. began transitioning to 100% carbon-neutral sources for its cheese-production facility in 2011, and has since fully achieved their goal with enough power left over to charge an electric vehicle.
- The company, uses a ground source heat pump and PV (photovoltaic) solar panels to achieve zero-emission status.
- Juliet Harbutt of the British Cheese Awards said the process even makes the cheese taste better in the end.

The energy required comes from a ground source heat pump that heats the water to 50 degrees and then our solar panels take the temperature up those last few degrees required ..."
