Actually, solar or solar energy is – the only clean – nuclear energy, because it is an energy produced by nuclear fusion, parts of which reach the earth as electromagnetic radiation. Solar energy can be used to generate electricity – photovoltaics – and/or heat – solar thermal energy – by shining sunlight on collectors.

However, solar energy is also the prerequisite for all other renewable energies:

  • Wind is created by sun-heated and cold air, thus creating the basis for wind power.
  • Biomass only grows with the help of the sun and enables the production of biogas, among other things.
  • Hydropower is only possible when rain falls – and this in turn only falls when water evaporates elsewhere due to solar radiation.
Support and realisation

Photovoltaic power plants

The Energiewerkstatt provides support from the project idea to the approval of an open-space photovoltaic system: This includes

  • Design planning
  • rezoning planning
  • Approval planning according to material law

Our experience in the field of wind energy enables us to provide yield calculations for combined wind and photovoltaic power plants to optimise the size of the plant for a given feed-in power.

1.7 TWh Power generation

Around 1.7 TWh (terawatt hours) of electricity were generated across Austria by means of photovoltaics in 2019. By 2030, this figure is expected to reach 12.7 TWh.

92,000 TWh Supply

The sun provides 92,000 TWh of energy in Austria every year.

15 billion years

the sun will still supply energy before its hydrogen supply is exhausted.
