Geothermal energy is making a comeback as engineers unlock deep-earth heat with new drilling and closed-loop technologies.

A new thermodynamic design links ion movement and concentration to energy output, creating soft polymer films that generate ...

Geothermal energy taps into heat beneath the Earth’s surface to generate electricity or provide direct heating. Unlike solar or wind, it never stops. It runs around the clock, providing consistent, ...

Heat has always been something we thought we understood. From baking bread to running engines, the idea seemed simple: heat ...

Shallow heat (a few metres deep) can be tapped by ground-source heat pumps, which heat buildings in winter and cool them in ...

Some industrial processes used to create useful chemicals require heat, but heating methods are often inefficient, partly ...

Geothermal energy can provide electricity, heating, and cooling by extracting heat from underground reservoirs.

"Studies have shown that heating your home to between 18C and 21C is ideal for staying warm without inflating your energy ...

According to the Energy Department, turning thermostats back 7 to 10 degrees for eight hours a day can save as much as 10% a ...

Scientists hope to prevent deaths from climate change, but heat and cold are more complicated than we thought.
