Solar thermal energy is the process of concentrating sunlight to generate heat, which can be used to generate electricity or heat a home, its water supply and more. Solar thermal energy can be used as ...

From a distance, the energy system on top of a college residence hall in Omaha, Nebraska looks like photovoltaic panels. But as you get closer, it becomes clear that this is something different, with ...

Italian researchers have reviewed different system configurations for photovoltaic-thermal solar-assisted heat pumps in buildings. They say that using the PV-thermal collector as the heat pump’s ...

Since ancient times, people have found ways to use the sun’s heat to stay warm or keep cool. They built homes from clay and other materials that hold heat well, and they placed them in ways that ...

“You stand in the sun on a cold winter day, you feel the warmth – put that warmth into water, you have got solar thermal energy,” describes Christophe Williams, co-founder and CEO of Naked Energy. “It ...

U.S. solar thermal panel manufacturer Fafco has developed a photovoltaic-thermal heat pump solution for water and pool heating. “The solution utilizes an open-loop solar drain-back style system that ...

DOI: Economics of Grid-Tied Solar Photovoltaic Systems Coupled to Heat Pumps: The Case of Northern Climates of the U.S. and Canada Two new Michigan Tech studies show how heating with electric heat ...

Portal’s heat exchanger thruster, known as Flare, fires up during a test in a vacuum chamber. (Portal Space Systems Photo) Bothell, Wash.-based Portal Space Systems says it has successfully tested its ...

A passive solar-heated home needs no solar panels to heat or cool it. Rather, the energy used to heat and cool a house comes directly from the sun through skylights and windows. Some of that energy is ...
