Energy resources: SwitzerlandElectricity production: Hydraulic and nuclear energy represent 95% of Switzerland's electricity production, of which 56% comes from hydraulic energy and 39% from electricity. 'nuclear energy. Hydropower, obtained from the energy produced by the movement of water, is widely used in Switzerland due to the country's topography and high rainfall. There are 556 hydroelectric power plants in Switzerland, with the majority of hydroelectric production coming from mountainous cantons such as Graubünden and Uri. The main element of a hydroelectric power station is a dam that holds back water, creating a reservoir. The water in the reservoir has potential energy, which is transformed into kinetic energy as it flows through the water intake and penstock. The water then hits the turbine, spinning its blades, which are attached to the generator, where a series of magnets begin spinning in front of copper coils, producing alternating currents through the induced movement of electrons. The current is then converted into a higher voltage current by transformers, after which it flows through power lines. Nuclear power involves the use of exothermic nuclear procedures to create electricity. Switzerland has a total of 4 nuclear power plants with 5 operational reactors. Nuclear power plants produce electricity by nuclear fission with uranium-235 atoms. The process involves a free neutron striking an atom of U-235; making it unstable and splitting it into two nuclei, which also emit neutrons which strike other nuclei, creating a chain reaction. This releases heat that warms the water, turning it into pressurized steam, which spins a turbogenerator that creates electricity. To maintain this chain reaction, the moderators (in the middle of the article ......Works cited • http://www.bfe.admin.ch/themen/00490/00491/?lang=fr• http: //www.swissgrid.ch/swissgrid/fr/home/reliability/energy_sources.html• http://en.wikipedia.org/wiki/Hydropower• http://science.howstuffworks.com/environmental/energy/ hydroelectric power plant .htm• http://en.wikipedia.org/wiki/Nuclear_power• http://science.howstuffworks.com/nuclear-power2.htm• http://www.greenpeace.org.uk/nuclear/problems• http ://www.wagingpeace.org/menu/issues/nuclear-energy-&-waste/nuclear-energy-fact-sheet.php• http://www.technologystudent.com/energy1/hydr2.htm• http:/ /en.wikipedia.org/wiki/Solar_energy• http://science.howstuffworks.com/environmental/energy/solar-cell.htm• http://www.technologystudent.com/energy1/solar7.htm• http:/ /www.ecovillage.org.in/ecopedia/alternate-energy/advantages-and-disadvantages-of-biogas/• https://www1.eere.energy.gov/wind/wind_ad.html
