Grant welcomes landmark Renewable Heating Obligation (RHO) Report published by TAZCH
The new reports details how the Irish Government could slash residential heating emissions quickly, cheaply, without disruption to consumers and at zero cost to the taxpayer. This can be done by altering its proposed Renewable Heat Obligation (RHO) rates of 1.5% and 3% and introducing a 20% blend of renewable liquid fuels. This small change would create the equivalent carbon saving of installing 160,000 heat pumps, without the need for costly retrofitting, disruption to households, or grid upgrades.
