Zero carbon energy scenarios such as ZeroCarbonBritain feature significant electrification of energy demands previously provided by fossil fuels such as heating and transport. With electrification it becomes possible to supply these energy demands with renewably generated electricity from primarily wind, solar and backed up by storage technologies from short term stores such as batteries to long term stores such as power to gas.
We do not of course yet have a zero carbon grid. However there has been significant growth of renewable energy and a decline in coal generation in recent years.
The CO2 emissions of demand side solutions such as heat pumps and electric vehicles are significantly affected by the co2 intensity of the supply but in many cases installing and using these technologies make sense at the UK’s present supply mix and can make more or less sense depending on how you calculate co2 intensity and where you assume the additional electricity required comes from.Read on →
