Researchers from Hebei University of Technology in China have proposed an integrated energy system that combines solar-driven reversible heat pumps with organic Rankine cycle (ORC) technology to ...

Cutting electricity costs is the usual pitch for rooftop solar, but studies indicate the panels may also help blunt extreme summer heat by slightly cooling buildings and even urban areas. Modeling ...

Researchers in the Netherlands have simulated a residential energy system combining PV, solar thermal, and PV-thermal panels with aquifer thermal energy storage and a heat pump, achieving a seasonal ...

For as good as solar panels are at converting sunlight directly into usable electricity, especially for how cheap they’re becoming, they can still only gather around 20-30% of the energy that hits ...

Buildings spew nearly 40 per cent of the world's planet-warming emissions and the amount is growing, says a new UN report. That's partly because fossil fuels still dominate heating and cooling. The ...
