In the United States alone, there are 437 billion square feet of windows installed every year. Imagine if all of those windows and the already existing windows on earth could produce solar energy to power the very buildings they adorn.
The idea of a transparent “solar-panel window” that could turn a high-rise glass tower such as One World Trade Center in New York, into one enormous solar panel is not some far-fetched idea of the future. Several companies, including SolarWindow Technologies and Onyx Solar, boast products that could not only reduce a skyscraper’s reliance on the grid, but possibly power entire city blocks one day. These solar panels embedded into windows have a minimal effect on the window’s aesthetic and maintenance.
