Edie Taylor, Rebecca Esau and John Matson at Rocky Mountain Institute explain how their report “Grid-Interactive Efficient Buildings Made Easy” identifies simple, low-cost steps that produce immediate cost, energy, and carbon savings. As utilities evolve their pricing structures to encourage users to avoid peak times, building managers must ready themselves with the controls that will allow them to buy electricity when it is cheapest. Demand … [Read more...]
Perovskites: the next generation of solar cells and lighting?
Enthusiasm about the discoveries being made about perovskite materials is spreading, explains Sam Stranks at the University of Cambridge. Perovskite solar cells hit 25.2% efficiency in 2019, not far off crystalline silicon cells at 26.7%. Research is suggesting that figure could rise higher still. Perovskite can be “tuned” to absorb particular frequencies of light, allowing different layers of perovskites to absorb different and therefore more … [Read more...]
Ad van Wijk: “The energy sector has nothing to do with energy companies anymore”
There are many developments in the world today that have far more influence on the energy sector than the energy sector itself, says technology visionary Ad van Wijk in this exclusive interview with Energy Post. The Professor in “Future Energy Systems” at Delft University of Technology in the Netherlands explains how LED lighting, a DC grid, fuel cell cars, the Internet of Things and 3D printing are upending our energy system as we know it. “The … [Read more...]
