1. 1. Wind to elec plus heat pumps with ccgt as interim 2. wind to DH with chp as interim  Both routes use gas for windless days back up.  Important question because building heating is the largest use of primary energy apart from transport

2.  The Elec route needs extra power cables since they are not big enough if all houses in a city had electric heat pumps  The DH route needs expensive DH mains to be laid.  Both need digging up the streets  Both need storage  Maybe insulation

5.  Heat stores store and forward surplus wind energy  CHP can coast at lower load with any spinning reserve losses captured as useable heat  CHP can switch to elec only mode with instantaneous increase in power, and vice verse AND  CHPDH can utilise: solar, geothermal, industrial waste heat

6. Inter-seasonal have been designed

7. Food for thought!
