If Billy Costello had his way, at least 2% or 3% of Ireland’s 10m acres of land would be dedicated to creating biomethane.

And as well as beef and dairy farmers, he thinks we should have energy farmers who are paid to grow and cut grass that could be used in the production of electricity and biomethane for vehicles at plants like his.
