A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground.
It uses the earth as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency. Ground source heat pumps are also known as “geothermal heat pumps” although, strictly, the heat does not come primarily from the centre of the Earth, but from the Sun.
Four Technology Challenges Aim to Decrease Energy Consumption in Buildings and Reduce Greenhouse Gas Emissions
The New York State Energy Research and Development Authority (NYSERDA) today announced the availability of up to $4 million in its first round of technology challenges for innovative clean energy companies to develop, commercialize and
Grants Will Support Innovation and Job Creation
Today, US Secretary of Energy Rick Perry announced that the Department of Energy will award 263 grants totaling $116 million – including 56 grants in California totaling $22.5 million. Funded through DOE’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR)

If owners of commercial office buildings can incorporate variable-frequency drives (VFDs) into their HVAC systems, more often than not they probably should, says Pete Miceli, vice president, regional engineering manager for real estate service, development, and investment management at Transwestern’s Midwest office. Recently, Transwestern installed VFDs for supply and return

Although every situation is unique, and it’s difficult to generalize, Barry Worthington, executive director of the US Energy Association (USEA) in Washington, DC, says progress in renewable energy over the last 10 years has been phenomenal as systems become more efficient. Nevertheless, use of renewable energy for onsite power generation

Caves aren’t really cold, but they aren’t really warm either. In a nutshell, that explains a bit about how geothermal systems derive their energy. For anyone who has gone caving or simply visited one of the many stunning caverns throughout this country, wearing a light jacket is often advised no
“Utilities continue to find it extremely challenging to fund and manage capital projects while keeping rates low and stable. They’re embarking on asset management programs while finding ways to reduce operating costs and increase revenues through energy-related projects. . . . These programs are increasingly delivered through public private partnerships
