Solar energy

Both heat and electricity can be generated from the sun's radiation. Photovoltaic modules on rooftops or in open spaces use semi-conductors such as silicone to convert sunlight into electrical energy. Solar collectors with circulating liquids are used to obtain heat for heating buildings and water as well as for cooling buildings. It is also possible to generate electricity, process heat and cooling by concentrating and amplifying the sun's rays. The sunlight is concentrated via reflectors and converted into steam with which a generator or a heat and cooling machine is operated.
