The relative competitiveness of renewable electricity and renewable heat depends on a nation's approach to energy and environment policy. Few renewable technologies (whether for heat, electricity or transport) are competitive with fossil fuels without some form of carbon valuation or subsidy. In those countries, such as Sweden, Denmark and Finland, where government intervention has been closest to a technology-neutral form of carbon valuation (i.e. carbon and energy taxes), renewable heat has played the leading role in a very substantial renewable contribution to final energy consumption. In those countries, such as Germany, Spain, the US, and the UK, where government intervention has been set at different levels for different technologies, uses and scales, the contributions of renewable heat and renewable electricity technologies have depended on the relative levels of support, and have resulted generally in a lower renewable contribution to final energy consumption.
