Storing wind energy underground

Pumped storage power plants have been in use for over a hundred years to balance fluctuating electricity loads and to cover peak loads. The energy transition creates additional storage demand with its fluctuating feed-in of wind and solar power into the grid. New sites, however, are scarce. Whether the large differences in the tunnel heights of abandoned mines are usable or not is currently being investigated by an interdisciplinary team of researchers on the basis of two viable locations.  more...

Sustainable use of deep geothermal energy

The alpine foreland is experiencing a geothermal energy boom. The region boasts a vast quantity of deep geothermal water. In the Greater Munich area alone, 15 geothermal heat stations and power plants are currently either in operation or under construction. Geoscientists led by the Leibniz Institute for Applied Geophysics (LIAG) have studied the geological and hydraulic conditions of the region and developed a simulation model. This model can now be used to better predict the interplay between power plants, long-term operation and exploration risks of new plans.  more...

Solar thermal power plants

The annual solar irradiation on the earth provides more than 8,000 times the world’s energy requirements. Mathematically speaking, about 1 % of the surface area of the Sahara Desert is sufficient in order to meet the world’s electricity requirements with solar thermal power plants. A solar thermal power plant was already constructed close to Cairo at the beginning of the 20th century. Using parabolic mirrors, the power plant captured and concentrated solar energy and used it to heat oil for boiling water. This in turn was used to drive steam turbines and produce electricity.  more...

Electrically driven heat pumps

Electric heat pumps have become firmly established in the German heating market. In recent years they have gained an eight to ten per cent share of the market. Approximately every fourth new building is heated with a heat pump. Whereas until a few years ago ground source heat pumps were still sold the most, the sales figures have shifted in recent years in favour of air source heat pumps. Carefully planned, heat pump systems compare very economically with other heating systems.  more...

Schools plug into the sun

Photovoltaic systems in schools help save energy and enhance classroom teaching. They shape a school's image and indicate that energy supply is a future-focused subject. Grants are available to schools wanting to install photovoltaic panels.  more...

Schoolchildren are saving energy

At many schools they already exist: schoolchildren as energy detectives, energy managers or energy teams. They track down energy leaks, take the initiative, assume responsibility and ultimately know a great deal about saving energy. Their commitment is often also financially rewarding for their school.  more...
