Renewable energy for your home

Renewable energies are now extremely important for climate protection and a secure power supply. Heat pumps, pellet heating systems and photovoltaic systems are some of the possibilities for using renewable energies for power generation and heating.

In addition, energy suppliers are already offering options for purchasing electricity and heat from renewable energies. This article shows how renewable energies can be used in your own four walls.

In comparison to fossil energy sources such as oil, coal or gas,renewable energies are sources of energy that are available to us in almost unlimited quantities. They are, as the name suggests, renewable.

These include:

Utilising renewable energies is an effective and environmentally friendly way to generate electricity and heat. Ongoing research and technical development are driving forward their expansion and use.

The following technologies are already available for using renewable energies at home.

Among the renewable energy methods that can be used at home are pellet or wood chip heating systems, which are becoming increasingly popular. These systems burn waste products from the wood industry, wood chips or pellets of pressed wood shavings, in a boiler. The heat generated can heat water, which is then fed into the heating system and/or can also be used for hot water.

Heat pumps can produce heat in different ways. This is done either from the water, the air or the earth. This heat can then be used in the heating system and for hot water. However, heat pumps require energy in the form of electricity or fuel to be able to perform their tasks.

The heat pump's energy consumption can be considered economical as long as the differences in temperature of the environment and the flow temperature of the heating system are not too great. It is therefore recommended to use the heat pump in conjunction with underfloor heating or a low-temperature heating system. In this context, it is worth investing in a PV system for electricity consumption.

Photovoltaic systems use solar cells in PV modules to generate electricity from solar energy. The performance of the PV system varies depending on the intensity of the sunlight, which changes with the seasons, and the efficiency of the system.

The type of installation and the location also play a major role. A PV system generates direct current, which must be converted into alternating current by an inverter before it can be used.

Solar thermal energy systems convert sunlight or solar energy into heat energy. This can be used for heating water and for heating. The output of the solar thermal energy system depends on the duration and intensity of solar radiation and the efficiency of the solar panels. A solar thermal energy system can also be used to cool the apartment or house.

Please note: a solar thermal energy system cannot generate electricity!

Photovoltaics are not the only popular way to reduce energy costs today. Solar thermal energy also plays an important role today. A lot has changed and been developed in the field of solar thermal energy since the 1980s. This has resulted in various options for extensive solar thermal energy use.

Solar collectors are usually installed on sloping roofs, where the carrier medium absorbs solar radiation and heats up. The heat is then passed on to a heat exchanger, which transports heat to a storage tank. This heat can be used to heat water or to provide heating. Up to 20 percent of a surface heating system can be supported by solar heating.
