Energy is a physical quantity that determines our everyday lives: We need energy in the form of electricity to illuminate light sources, such as your ceiling light at home. Vehicles only move with energy. And thermal energy keeps our heaters warm. The unit of measurement for energy is the joule, named after energy researcher James Prescott Joule.
A major societal goal is to save energy to conserve the earth's resources. Smart home devices can help you achieve this:
- With a smart home heating thermostat, you can save a lot of energy – and therefore costs – when heating.
- Motion detectors ensure that lights only come on when someone is present in the room. You no longer waste energy by accidentally turning on lights.
- With smart sockets, you save standby energy from connected devices: the socket is only activated when the respective device is actually needed.
- Smart awnings and shutters automatically lower when the sun is shining brightly, keeping interiors cool. This helps reduce air conditioning costs.
