Whichcompanyownsthe majority ofpowerplants in theCzechrepublic? ČEZ • = České energetické závody • Wasfounded in 1992 • Isthe most dominant producerelectricity in theCzechRepublic • Simpleeffortsthatmakessmallimpacts on environment produceselectricityalso fromrenewableresource
Firstrenewableresourceisbiomass. BIOMASS • There is lots of energy in biomass • It has minimalecologicaldamage
Whatisthebiomassmadefrom? BIOMASS • Basic source: plants • In theCzechrepublic • Wood • Straw • Agriculturalwaste • Animal’s excrements
Biomass energy center in Jindřichův Hradec • Basic fuel: • Straw bales • Hay bales • Fast-growingplants • Fueliscollectedfrom70 km radius of the town Biomass incineratorisdirectly in ourtown.
Biomass energy center in Jindřichův Hradec • April2009 it wasbought by CEZ Group • It covers 35% heat consumption
Biomass energy center in Jindřichův Hradec • Yearlyitproduceshere more than 30 thousand MWh • Whichistheannualconsumption in 8,500 households
HYDROELECTRIC POWER PLANTS • Ourwatersheds aren’tadvatageous for hydroelectric power plants • Hydroelectric power is used as supplementary energy • Advantage is immediate use Second reneawableresource iswater.
HYDROELECTRIC POWER PLANTS • Most of them are situated on the Vltava river → theVltava cascade • 21 water cannons make 83 % renewableenergy ČEZ
HYDROELECTRIC POWER PLANTS • Long-time practice of tradition • In earlier times waterwas powerfor mills, sawmills, and hammer mills water mechanical power • The oldest hydroelectric power plant: built 1888 inPísek Historyofhydroelectricpowerplants

CEZ Group in Turkey • CEZ Groupowns business shares in companies, which run 8 hydroelectricpowerplants in Turkey • E.g. Bulam in southeastTurkey CEZ suppliesnatureconservativealso in otherstates – forexample in Turkey.
SOLAR POWER PLANTS • Environment: theclearestandthe most environmentallyfriendlyway • Highpotential in future The last renewableresourceis sun enegy.
SOLAR POWER PLANTS • Solarcells • Firstsolarpowerplant isfrom 1997 Photovoltaic powerplant Dukovany
SOLAR POWER PLANTS • Solar boom • Extremellylowpurchaseprices • Government’s plan: solar cells on roofsandfields • The same price was also for big power plants in country • Expensive energy→ high priceofenergy for comsumers Abuse oflowpurchaseprice!
