In the 1990s when prices of natural gas dropped, so did interest in solar thermal power. Today, though, the technology is poised for a comeback. It's estimated by the U.S. National Renewable Energy Laboratories that solar thermal power could provide hundreds of gigawatts of electricity, equal...
How Solar Photovoltaics Works Solar PV works by converting solar energy into electricity. The sun’s rays contain photons which are particles that transmit light or other forms of electromagnetic radiation. These photons are key for the photovoltaic process to work. Solar panels (solar cells) are ...
How Solar Thermal Power Works By: Maria Trimarchi Solar thermal power keeps chugging even when the sun goes down. See more pictures of green living. AP Photo/SkyFuel, Jack Dempsey Most of us don't think much about where our electricity comes from, only that it's available and plentifu...
What exactly is geothermal energy, and is it the future? What are the advantages and disadvantages? We unpack this member of the clean energy family.
A thermal battery consists of a stack of cells each made from a cathode, an electrolyte separator, an anode and a pyrotechnic, thermal energy source. The battery can be activated at any time without preparation, and will begin supplying power almost immediately. Once activated, the battery funct...

Most large inverters will allow you to automatically control how your system works. Some PV modules, called AC modules, actually have an inverter already built into each module, eliminating the need for a large, central inverter, and simplifying wiring issues. ...
Energy storage systems come in many different sizes, weights, and certainly at different prices. Learn more about how all that works here!
Thermal Imaging The basic components of a thermal-imaging system Image courtesy of Infrared, Inc. Here's how thermal imaging works: A special lens focuses the infrared light emitted by all of the objects in view. The focused light is scanned by a phased array of infrared-detector elements...
