4 WE

5 TOPICS Sources of energy Power plants Water energy First street lamps Traffic lights

6 RESEARCH QUESTIONS What were the sources of energy in the past? When were the first lamps installed? How did street lamps change? How do nuclear power plants work? How is the power of the river Nitra used? What do people mostly use for heating? How does insulation help? What alternative sources of energy are suitable Nitra?

7 ENERGY PAST

8 SOURCES OF ENERGY 1915 – Whole Nitra was electrified – Hydroelectric plant was built in Nitra » 1972 – nuclear power plant Jaslovské Bohunice » 1998 – nuclear power plant Mochovce.

9 STREET LAMPS 1890 – the first gas street lamps were placed in Nitra.

10 STREET LAMPS IN NITRA Theatre of Andrej Bagar Pedestrian zone Medical institution

11 TRAFFIC LIGHTS March 17 th Inteligent traffic control system was installed in Nitra. It is a system by which traffic lights respond to changing traffic conditions.

12 MAIN CROSSROAD IN NITRA

13 ENERGY PRESEN T

14 HYDROELECTRIC PLANT 1950 – Hydrocentral was built in Nitra » 2004 – the turbine was improved. Water flow rate is 18 m 3 /s.

15 HYDROELECTRIC PLANT NOWADAYS

16 NUCLEAR POWER PLANT JASLOVSKÉ BOHUNICE 1972 » 1979 – Reactor Bohunice A » 2006 – Reactor Bohunice » 2008 – Reactor Bohunice » 2015*- Reactor Bohunice » 2015*- Reactor Bohunice-4 * - Planned

18 NPP MOCHOVCE BLOCK I » 1998 – Building Block I » 1995 – Building was stopped. 2028* » 2030 *– Planned turning off block I. BLOCK II » 2008 – Building Block II. 2012* » 2013* – Starting Block II. * - Planned

20 HOW DO NUCLEAR POWER PLANTS WORK? It begins when uranium is mined, enriched and transpotred into nuclear fuel, which is delivered to a nuclear power plant. After usage in the power plant, the spent fuel is delivered to a reprocessing plant or to a place for geologic trash. In recycling, 95% of spent fuel can be recycled to be returned to usage in a power plant. The Nuclear Fuel Cycle

21 HEATING People in Nitra heat their homes with gas or electricity. Gas is taken from Slovak gas industrial building near Nitra in Ivánka pri Nitre. Gas is tranported by pipeline.

22 ENERGY FUTURE

23 INSULATION Many buildings in Nitra are going to be repaired and insulated. Slovak Republic has earmarked some money for insulating.

24 INSULATED HOUSE INSULATED WALL

25 NITRA IS LOOKING FOR ALTERNATIVE SOURCES OF ENERGY Solar energy, biogas or energy from thermal springs – these are the most realistic alternative sources of energy for the town according to Jozef Dvonč, the Nitra major. The Energy Agency was estabilished by Nitras self- administration with the finnancial suport of from the EC Program. Its going to deal with possibilities of their usage.

26 POEM Nitra is a big city, it saves elecricity. We use nuclear power, we love Nature our mother. We heat with renewable sources, we use another nature forces, because we dont have any seas.
