Creating microclimates in ovens

Fan-forced or convection ovens can be found today in many households. They work very efficiently if they are used for longer baking or roasting processes and are fully loaded. However, the devices are not optimised for preparing snacks or small dishes with a short cooking time. In the “ecoBack” project, researchers are investigating how a microclimate adapted to the food can reduce the energy requirement.  more...

Energy from waste water supplies urban district

Using waste water with organic substrates to produce biogas makes it possible to meet a large part of the electricity and heat demand in urban districts. This is being implemented on the site of former army barracks in Hamburg. This is where the new Jenfelder Au urban neighbourhood is being created with around 770 residential units. The drainage and energy concept provides for separate drainage of the domestic sewage already within the buildings and the conversion of the black water into biogas. The aim is to supply CO2-neutral heating.  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...
