Although heating accounts for more than 40% of total final energy demand – more than the entire power sector – it does not rank high on the agenda in energy debates. Policies for the heating sector must address both supply and demand, and account for major differences between home and office heating (which is climate/weather dependent) and industrial process heating (which is not). The good news is that heating technologies can help integrate variable solar and wind power into the system with a range of technology options.
