Researchers in Spain have proposed two control strategies for the integration of heat pumps in district heating systems assisted by solar thermal collectors. Their technical-economic analysis shows ...

Researchers in Malaysia designed a photovoltaic-thermal system that can be used in solar drying, space heating, rooftop systems, and off-grid thermal applications. It relies on a double-pass cooling ...

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 ...

Solar collectors and absorbers convert solar radiation into thermal energy, playing a crucial role in meeting global heating demands across various sectors.

Passive cooling, like the shade a tree provides, has been around forever. Recently, researchers have been exploring how to turbo charge a passive cooling technique — known as radiative or sky cooling ...

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 ...

Despite widespread global success and huge opportunity for reducing fossil fuel demand, solar water heating is virtually unheard of in the U.S. Evidence suggests our demand for simple fixes is to ...

A solar pool heater uses a pump, a solar collector and piping in conjunction with your existing pool filter. The process is simple: The pump takes water from the pool, then forces it through the ...

Q: We need some extra living space and think adding a sunroom might also heat our house. We might get a kit or start from scratch. Do you have tips for either approach? A: If you want more living ...
