Energy for Your House

In many houses and apartments, electrical energy is

wasted, usually through carelessness or convenience.

Electronic controls, often connected to the internet and

controllable via apps, can reduce this unnecessary

electricity consumption. For example, they only switch on lights when someone is

moving in the room and it is dark. They control the heating and turn it down when

the sun is warming through the window. They open and close shutters to achieve

optimal insulation at night, even when no one is in the house. A house equipped in

this way is called a smart home. Whether such technology is installed in a house

must be carefully considered: scrapping functional devices and technology to

replace them with “smart” technology may be a waste of resources.

Storing solar

energy?

The generation of electricity from sunlight suers from the fact that clouds and

winter days with little sun can signiﬁcantly reduce the performance of solar

cells. They also do not produce any electricity at night. On sunny days, however,

solar systems may produce more electricity than is needed in the house that day.

There are several technical ways to deal with this problem: you can feed excess

electricity into the public power grid, and even get paid for it. Or you can store it

in large battery systems to use when there is no sun. You can also automatically

switch on larger electrical devices in the house only during times

when there is a surplus of electricity. An electronic control

system then distributes the electricity only to where it is

needed. For example, to the washing machine, to the

heating in winter, to the air conditioning on hot summer

days, or to a charging electric vehicle.
