Danish lighting company Scotia unveils new range of solar-powered streetlights that promise to turn local authorities into ‘energy powerhouses’ London may take a lead in zero-emissions street lighting later this year if plans go ahead to install the first wave of a pioneering streetlight that illuminates streets and feeds energy back into the grid using only solar power. The Monopole street light, developed by Danish solar lighting firm Scotia, collects solar energy during daylight hours and stores it in a battery for use after sundown. Not only do the lights generate enough energy to power themselves, they can also feed energy back into the local grid to turn local authorities into “energy powerhouses”, according to Scotia’s founder Steven Scott. According to Scotia, if all of the UK’s seven million streetlights were switched to Monopoles, it would save more than £300m in electricity costs and generate more than 4TWh of clean power per year. Some 40 per cent of this would feed back into the grid, saving more than two million tonnes of CO2 every year, it added.
