COMENIUS 1 school-partnership Slovakia EUC Meeting in Germany Tábor, CZ 7. 4. – 11. 4. 2014 Střední průmyslová škola strojní a stavební, Tábor Czech Republic SREDNA ŠKOLA Oroslavje, Croatia Slovenia Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Poland Darıca Ülkün Yalçın Anadolu Lisesi Türkey 1 COMENIUS 1 school-partnership Present sources of electrical energy What is energy? A simple question with a difficult answer. Most Slovakia often you will learn that it is the ability of mass to do work. Scientists assume that the energy in the universe exists in the same quantity since the Big Bang, only changing its form. We know mechanical, magnetic, thermal, nuclear, and electrical Germany and many others. For our life it is very important only the electric. With electricity shining our light work of home appliances, there is internet, flowing water, car rides, etc. Where, however, takes electricity? Střední průmyslová škola strojní a stavební, Tábor Czech Republic In the drawer? Electrical energy is transformed into another type of energy using generators. Most often converts mechanical energy that rotates a generator. Mechanical energy used by people even in times past, for SREDNA ŠKOLA Oroslavje, example in water or wind mills, today the wind energy and Croatia transforming the water in hydro and wind power plants just to power. Since the steam engine, where we can utilize the power of the steam to move, we can use this power as well as the Slovenia production of electricity in thermal and nuclear power plants. Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Poland Darıca Ülkün Yalçın Anadolu Lisesi Türkey 2 COMENIUS 1 school-partnership Sources of electricity: Thermal Slovakia Thermal power plants use to shake, power generator steam. To produce water steam, it is necessary to supply heat to the water. As a source of heat power plants using fossil fuels such Germany as coal and natural gas, or biomass. After heating the resulting steam flows through the turbine and rotates the generator that generates electricity. It is the most common type of power peak production. Due to the limited amount of fossil fuels is their Střední průmyslová škola strojní a stavební, Tábor future uncertain. Czech Republic SREDNA ŠKOLA Oroslavje, Croatia Slovenia Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Poland Darıca Ülkün Yalçın Anadolu Lisesi Türkey 3 COMENIUS 1 school-partnership Nuclear Nuclear power plant works on the same principle as heat, water Slovakia heating are, however, uses a controlled fission reaction, which occurs when the necessary heat. This power supply is better for environment and even with a smaller number of nuclear power plants, the share of nuclear energy quite high. Uranus but we Germany have a limited amount so in the future, this source is uncertain.

Hydroelectric power plants are dependent on water resources, but they are very environmentally friendly. Germany Střední průmyslová škola strojní a stavební, Tábor Czech Republic SREDNA ŠKOLA Oroslavje, Croatia Slovenia Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Poland Darıca Ülkün Yalçın Anadolu Lisesi Türkey 5 COMENIUS 1 school-partnership Wind Wind power generator rotor is spinning flowing air similarly as in Slovakia the case of windmills. This power supply is also very environmentally friendly, but it still depends on the weather. Germany Střední průmyslová škola strojní a stavební, Tábor Czech Republic SREDNA ŠKOLA Oroslavje, Croatia Slovenia Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Poland Darıca Ülkün Yalçın Anadolu Lisesi Türkey 6 COMENIUS 1 school-partnership Photovoltaic Solar panels use the energy of solar radiation and the Slovakia photoelectric effect. They are the only plants that do not use a generator convert’s mechanical energy into electrical energy. The disadvantage of these plants is that they produce only during the day and depend on the intensity of solar radiation.

The answer to this question is completely up to you. SREDNA ŠKOLA Oroslavje, In the first part of the task, search on the internet how big is the production of electricity in the country allocated to your group and how it contributes to whole different sources. Croatia The information collected add to the table and create a graph that presents your group meeting participants Comenius EUC. Slovenia Total production in ____________________________________________ (fill the allocated land) Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Annual production of electricity in this country is: ______________ Poland On the production is involved: Power source Thermal power stations Nuclear power stations Hydroelectric power stations Wind power stations Photovoltaic power stations Share [%] Darıca Ülkün Yalçın Anadolu Lisesi Türkey 9 COMENIUS 1 school-partnership If this country was replaced with thermal and nuclear power plants, wind or solar, how much would they be needed? Slovakia The overall performance of nuclear and thermal power plants: ____________________________ Power of solar panel is 5 kW Power of wind power is 3000 kW The number of required power Germany Wind power stations Photovoltaic power stations Střední průmyslová škola strojní a stavební, Tábor Czech Republic Energy Future People are using more and more electrical devices and growing demands for energy in industry. Therefore, researchers are beginning to examine what power source will be able to meet the needs of humanity. One tract is thermonuclear fusion. To become familiar with this technology to locate and process information related to this technology into the presentation. • • • • • • • The basic principle of fusion Cold fusion Tokamak Fusion´s advantages Fusion´s disadvantages Nuclear fusion in Europe ITER SREDNA ŠKOLA Oroslavje, Croatia Slovenia Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Poland Darıca Ülkün Yalçın Anadolu Lisesi Türkey 10 COMENIUS 1 school-partnership Slovakia Germany Střední průmyslová škola strojní a stavební, Tábor Czech Republic SREDNA ŠKOLA Oroslavje, Croatia Slovenia Zespół Szkółi Placówek Kształcenia Zawodowego w Bielawie Poland Darıca Ülkün Yalçın Anadolu Lisesi Türkey 11 12
