Scotland has the potential to create heating systems which can do much more to help us become self-sufficient in heating needs and less reliant on imported gas. Some of the technologies for this are still developing (such as inter-seasonal heat store where solar thermal energy is stored over the summer for use over the winter). Others are much better developed (such as biomass where Scotland has potentially enormous land resources which could be used to create wood pellets for biomass boilers). These kinds of systems should be built into new housing developments as district heating (where a block or entire street can be fed from one large and super-efficient boiler, with houses metered for hot water use). They can also be retrofitted. The National Energy Company (see part #35) should be tasked with developing plans for innovating Scotland's heating infrastructure.
