Geothermal Heat Pumps - Their Role in Global Cooling

Abstract

It may not be intuitive - that geothermal heat has a role in reducing global warming. Geothermal heat pumps are the fastest growing sector of the geothermal energy market. What is not often understood is the significant role they can play in reducing the emission of carbon dioxide. The heating and cooling of buildings is one of the largest contributors to carbon emissions due to the predominant use of fossil fuel in this sector. The IEA recognises that heat pumps are one of the most significant, single technologies for reducing carbon pollution. This paper explores how geothermal heat pumps are delivering growing, ongoing, carbon reductions, as well as offering advantages in terms of reduced heating costs, security of supply, energy efficiency and delivery of renewable energy.
