Thanks to new technologies in households, significantly more energy-saving alternatives have become established in recent years. Especially LED lighting compared to conventional light bulbs makes a huge difference. In traffic, e-bikes and e-scooters replaced many mopeds and scooters. If the weather is good, they are also replacing a steadily growing proportion of short-distance car traffic.
In IT, engineers have trimmed systems for greater efficiency for years; laptops, for example, consume significantly less power (around 60 watts) than desktop systems (around 130 watts, as of 2020). The shift in internet use to mobile devices also plays a role. In the field of consumer electronics, LED technology is the primary energy source in televisions and projectors today. Nearly all cathode ray tube (CRT) or plasma screens with high power consumption have been replaced in European homes.
All these technologies should actually contribute to a reduction in household electricity consumption – but the effect is small to non-existent. One reason for this is the need for growth that underlies our economic system: Consumers shift from operating not only one power-hungry device but countless small devices around the house. Ten LED lamps of seven watts each consume 70 watts per hour, too. Every there is not only one but a second, third and fourth screen that must be charged or operated on a power supply unit. In companies, however, whose lighting systems have to be much more efficient, there is a great energy saving potential in converting from halogen or neon lighting to LEDs.
Renewable energies have shown and proven that they can supply electricity in a clean and safe way. Nevertheless, apart from electricity generation, there is much left to do. The conditions for the energy transitionare sometimes more (as in heat generation and industry) and sometimes less (as in transport) favorable. If all energy consumers in the economic system turn to electricity from renewable energy sources, the electricity grid will have to meet enormous demands. The grid operators can deal with this challenge effectively through an intelligent and flexible use of networked electricity producers, consumers and storage facilities.
