Curved molecules that absorb sunlight, store the energy, and re-release it as heat are pushing the boundaries in solar ...

As climate change and growing energy demands strain global systems, scientists are increasingly turning to passive cooling technologies—ways to cool objects or spaces without using electricity ...

Photothermoelectric (PTE) effect involves two energy conversion processes: photothermal conversion and thermoelectric effect. When the incident light is locally absorbed, a temperature difference ...

Incandescent bulbs produce light by using electricity to heat a wire filament until it glows. The drawback is that the bulbs use 90% of their energy to produce heat . CFLs use about 80% for heat.

Letting in light (and the view) is one thing, but with light comes heat, especially in the hotter months. On hot days, up to 87% of heat gain in our homes is through windows.
