Observing the renewable energy transition from a European perspective

Next-gen Color Electrowetting Display

Increasingly, people are switching their many LED electronic devices and computer monitors into so-called “dark mode”, with the intent to reduce light intensity. A more permanent solution could offer an innovation from a Philips Electronics spin-off named Etulipa. They can produce non-radiant monitors that act like paper and merely reflects ambient light. Amazon customers are likely familiar with its easeful black-and-white Kindle reader. Etulipa is able to produce a color display, with an energy consumption in the order of a few Watt, see video above, based on R&D that is more than 20 years old. Additionally, screens can be scaled to really large sizes. To compare: LED screens consume 350 W/m2 or 800 W/m2 in full daylight, Etulipa’s e-paper merely 5 W/m2 and thus is suitable for off-grid operation, combined with some solar cells and battery.

When talking about the renewable energy transition, people often focus too much on replacing fossil with renewable capacity, but ignore the vast potential of saving energy, thanks to new technology: led-lights, heat-pumps, large A+++ freezers of 202 kWh/year, a small A+++ fridge of 60 kWh/year or TV’s and monitors with an electrowetting display.
