Low carbon technologies e.g. CHP could deliver a better overall result than renewables in many real situations. The review highlights the carbon and energy headlines in the model data because they tell different sides of the story
Typically heat demand is easier to tackle than electrical demand, but always address efficiency and optimisation before considering LZCT, which should be considered in the context of the following preference hierarchy:
- Passive design
- Solar DHW
- Renewable Tri/co generation
- Tri/co generation
- Community heat cool networks
- Ground heat pumps
- Heat pumps
- Gas condensing heat
- Traditional heat
Remember that solutions that address small carbon problems yield small reductions
