A new heat-to-energy converter has reached a record efficiency of 44% – the average steam turbine manages about 35%, for comparison. This thermophotovoltaic cell is a major step on the way to ...

Heat batteries quietly solve a major transition gap, storing surplus renewable electricity as heat. Half of global energy demand is for heating, not power. They are simple, scalable, and far cheaper ...

Researchers designed a novel heat pump that uses sound waves to move thermal energy, producing additional heat. The team from China produced an unprecedented amount of heat with their system, and ...

The systems, which can store clean energy as heat, were chosen by readers as the 11th Breakthrough Technology of 2024. We need heat to make everything from steel bars to ketchup packets. Today, a ...

Home heating represents 80% of UK household energy use and 18% of GHG emissions EU targets 60 million heat pumps by 2030, but faces 344 billion euro climate investment gap District heating serving 70 ...

Heat pumps are the most energy-efficient way of controlling indoor temperature. By moving heat between locations, they avoid the inefficiencies of generating heat in the first place. But that doesn’t ...

Get a firsthand look at how a Pennsylvania home transformed its energy costs by making the switch to a heat pump. Faith Foushee is a CNET contributor and a former writer for SaveOnEnergy.com, covering ...

What's the difference between warm air and cool air? In fact, what does “temperature” even mean? It's stranger than you think. At a basic level, if you increase the temperature of air, you increase ...
