Directly connected to the electricity market – in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.</span><br style="border:0px solid;margin:0px;font-family:Arial, Helvetica, sans-serif;font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);"><br style="border:0px solid;margin:0px;font-family:Arial, Helvetica, sans-serif;font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);"><strong style="border:0px solid;margin:0px;font-weight:600;font-family:Arial, Helvetica, sans-serif;font-size:14px;font-style:normal;text-transform:none;background-color:rgb(255,255,255);">Want to take responsibility and build solutions that truly matter?
