A domestic property loses as much as 20 percent of its heat through windows. For big glassy commercial buildings, that figure is a lot higher, resulting in big heating bills and inevitable disputes ...

Semitransparent solar cells with natural looking color and strong heat blocking offer a realistic way for windows to generate ...

With the addition of some cheap nanoantennas, your average window can now be turned into an efficient solar heater. Just as Elon Musk’s Tesla wants to turn our otherwise dormant roofs into powerful ...

Windows are great for letting in light, but in summer months that comes with an unwanted side order of heat, causing many people to run the air conditioning non-stop. Now, researchers have developed ...

The National Renewable Energy Laboratory, (NREL), has demonstrated a prototype of a solar powered smart window. The smart window lowers building temperatures by shifting from clear to opaque under ...

Generating energy from sunlight is essential for reducing CO2 emissions. However, it takes a lot of space to install all the solar panels needed for our energy supply on land. What if you could use ...

A California energy startup has designed windows with built-in solar panels, which they hope will hasten the widespread transition to carbon-free electricity sources the state is encouraging with new ...

Q: I need help deciding whether to put solar film on my west-facing windows in the Seattle area, and, if so, whether the film should go on the inside or the outside. We have no air conditioning and ...

These windows—dubbed "thermochromic" for their ability to change colors in response to heat—can convert sunlight into electricity using minerals called perovskites and single-walled carbon nanotubes.

Q: I bought a house with bedrooms that face the south side of the house. During the summer, the heat in those rooms is brutal. They already have ceiling fans, but I am wondering if putting up some ...
