list: Further information on the experiment “B6 Renewable energies – Sun, water, wind
Information and ideas: Suitable as a source for Internet inquiry for teachers and students alike.
Solar thermal energy and photovoltaics – energy forms with a future Water and wind
Power supply and district heating a examples of central energy supply and require an extensive infrastructure. However, distributed and possibly even autonomous systems are also conceivable. Renewable energy sources are particularly suitable for this purpose. Information and ideas: What are the advantages and disadvantages of central and distributed energy supply systems? When and why did central energy supply develop and become established? And why is the distributed energy supply approach increasingly under consideration today?

The energy stored in the primary energy sources comes from different places. Most of it comes from the sun and is stored in different forms in fossil and many renewable energy sources. The residual head of the earth’s core is available in the primary source of “geothermal energy”. The energy in the tidal range comes from the earth’s rotational energy, and the energy in nuclear energy sources results from processes in the atomic nuclei of certain elements. Information and ideas: Students can think about the process on which all sources of energy are ultimately based. Which source of energy will be important in the future and why? The tidal range example has special educational value for physics classes, since it appears at first glance to be a perpetual motion machine. The question of “where does the energy of a tidal power plant come from?” cannot be truly answered by the statement “from the difference in water levels (m x g x h). It may be clear to anyone that the moon does the lifting work, but where does it get the energy to do that? After all, wherever energy is “gained” somewhere, it must be “lost” somewhere else. The correct answer is that the moon’s gravitational pull shifts the water masses of the oceans, which ultimately causes a slowdown in the earth’s rotation. The mechanical energy obtained in a tidal power plant therefore ultimately comes from the primary energy source of “the rotational energy of the Earth”.

The medium includes information on the power generated in individual countries, indicated in gigawatt-hours (GWh). An accompanying bar chart shows the percentage share of the individual countries’ power generation relative to global power generation. The share of the various energy forms in global power generation is shown in the bar chart for 2014 and 2017 and as a forecast for 2040. Information and ideas: With a comprehensive overview of power generation on a global scale, teachers can encourage students to think about the reasons why power generation differs in the various regions. Another question: How can we meet power demand in the future? Using the following sources: International Energy Agency (IEA); Statista
