Climate-change charity Possible has published a ten-point manifesto,listing priority projects,policies and changes to deploy over the coming decade to keep global heating below the 1.5°C threshold come 2050.The ten proposed ideas are: 1.COMMUNITY VOLCANO POWER: Several UK regions could support deep geothermal wells,tapping a continuous source of heat conducted from magma in the planet's mantle-either from hot sedimentary aquifers or from hot,dry rocks.Possible says geothermal heat could generate 4 per cent of annual UK heat-energy demand-and should be community-led.Southampton has generated clean electricity and heat for its district heating network from hot water under ground for more than 25 years.Central Scotland,Wessex,Cheshire and the east of England are sitting on similar hot-water reserves.Possible says it may be more commercially attractive to tap hot-rock energy,found below the Lake District,Weardale,Devon and particularly in Cornwall.A three-mile well near Falmouth completed flow tests this autumn and will generate its first energy this year.However,tapping the Cornish granite for renewable heat demands the same drilling equipment and processes as tracking for shale gas; it can cause seismic tremors.
