The key challenge in choosing an engine or turbine for a combined heat and power (CHP) system is to efficiently bring together thermal energy demand with systems that produce mechanical or electrical power, Manfred Klein, independent energy consultant ...

In the past however, most solar systems had just been either a solar thermal system or a photovoltaic systems. The former takes advantage of the sun's thermal or infrared energy, producing heat, which can be harnessed for solar hot water, like the ...

A solid, oxygen-laden material, called an "oxygen carrier," is put into contact with the natural gas where the oxygen atoms in the carrier interact with the natural gas, causing combustion. The combustion reaction is what produces energy. Previously ...

In some parts of the developing world, people may live in homes without electricity or toilets or running water but yet they own cell phones. To charge those phones, they may have to walk for miles to reach a town charging station—and possibly even have to leave their phones overnight. Now a startup company spun off technology developed at Lawrence Berkeley National Laboratory (Berkeley Lab) has created a simple, inexpensive way to provide electricity to the 2.5 billion people in the world who...

"The use of solar energy is increasing rapidly, and by 2050, the share of solar electricity may even represent one fourth of all the electricity used worldwide," predicts Professor Peter Lund of Aalto University. Solar energy ...
