Jenkins, who specializes in macro-scale energy systems, is also a consultant for Rondo and says the hot rocks model has a distinct advantage over chemical batteries that can store power, but not heat.

By trapping solar energy like a greenhouse, it heated the water to a scorching 180 degrees Fahrenheit. It furnished much of the hot water for a family of four. “We had no trouble with it,” my ...

A research team from Penn State has broken a 165-year-old law of thermal radiation with unprecedented strength, setting the stage for more efficient energy harvesting, heat transfer and infrared ...

Their advantages extend beyond reducing carbon emissions. Thirteen US states are now implementing underground thermal energy networks to reduce buildings’ carbon emissions as part of a ...

The pilot could be one of three that ConEd builds in and around New York City to test a cleaner way of delivering energy to customers. The proposals are in the design phase and likely won't be ...

Thermal energy networks are a clean and efficient way to heat and cool buildings. They use existing sources of thermal energy, such as waste heat or the earth, to enhance heating and cooling systems.

An old idea to use ocean heat to generate clean electricity has long failed to gain traction, but the technology – known as ocean thermal energy conversion (OTEC) – is seeing a resurgence of ...
