Why Geothermal Energy

• We need renewable heat in large

quantities

• We need minimum emissions

sources

• We would prefer to produce and

supply energy locally

Geothermal heat flux in the United Kingdom

(mW/m2)

Geothermal Energy at Banchory

• Public/Private Consortium investigating potential for

Geothermal energy at Banchory

• One of 5 projects funded by the Scottish Government

under the Geothermal Energy Challenge Fund

• Potential connection to existing and expanded Hill of

Banchory Biomass Heat Network

• Report will be published in Spring 2016
