BIOENERGYTilen Resnik, 3.G Tom Maierle, 2.E
WHAT IS BIOENERGY? A renewable energymade from biological
sources.We divide bioenergy into:- Biowarm or thermal energy,-
Bioelectricity or electricity from biomass,- Biofuels (solids,
liquids and gases).
WOOD BIOMASS IN SLOVENIA10.900 km of forests in Slovenia
(60%)More than 100,000 buildings
BIODIESELProduced from left-over food products,Biodiesel
consumption in Slovenia:- 2008: at least 2%,- 2009: at least 3,0
%,- 2010: at least 3,5 %,- 2011: at least 4 %,In the 5 years after
the year 2011: at least 5% of energy.
BIOETHANOLAn alcohol from organic materials.No transport on
bioethanol in Slovenia.
CHARCOALNew way of direct processing.Used for cooking and
heating, producing synthetic gas, etc.We have charcoal producton in
Pohorje and Koroka.
METHANEMethane is a chemical compound with the chemical formula
CH 4.Vehicles on methane gas are more eco.We have buses on methane
gas.2010: first car in Slovenia
COGENERATION OF HEAT AND ELECTRICITY Production of heat and
electricity at the same time . New technology already commercially
interesting
THE PRODUCTION OF HEATLocal heating: wood, pellets, wood chips,
etc.District heating: wood chips, peat, fuel from waste wood,
sawdust, and straw.

WHAT IS SOLAR POWER?Inexhaustible and renewable source of
energy,Electromagnetic waves,Part of the natural energy flows.
SOLAR POWER PLANTS IN SLOVENIA3215 operating solar power
plants,The best conditions are in the Primorska region.
SOLAR POWER PLANTS IN SLOVENIATotal output of 3,6 MW,The
strongest area represented in the tajerska region.
SOLAR PANELSUtilization of solar energy,Heating buildings and
water,Fragility
KEY BENEFITS OF THE USE OF SOLAR ENERGYInexhaustible source of
energy,Low maintenance costs,Lower consumption of fossil
fuels,Reduction of CO2 emissions.
USE OF SOLAR ENERGYPassive - solar system
USE OF SOLAR ENERGYActive - solar panels
USE OF SOLAR ENERGYWith photovoltaics - solar cells
SOLAR ENERGY IN SLOVENIASubstantial and far-reaching advance,
400 new solar plants in 2010,The primary promoter is the Slovenian
photovoltaic industry association.

Hydro & Geothermal EnergyMatej Kokalj, 3. FJan Deman, 4.

Hydroelectric energy
Geothermal energy
GEOTHERMAL ENERGYHeat from the Earth,Clean and
sustainable,Technologies taking advantage of geothermal energy.
Energy plants:dry steam power plants, flash steam power
plants,and binary cycle power plants.
DRY STEAM PLANTSSimplest & oldest design,Geothermal steam of
150C or greater to turn turbines.
FLASH STEAM PLANTS Flashed steam used to drive
turbines,Requirement of fluid temperatures of at least 180C,Most
common type of plants.
BINARY CYCLE POWER PLANTS Most recent development,Acceptance of
fluid temperatures as low as 57C.
GEOTHERMAL ELECTRICITY
GEOTHERMAL ELECTRICITY
BENEFITSEmissions contain few chemical pollutants and little
waste,Geothermal electricity sold to local power grids,Clean energy
for some of the worlds most rapidly expanding economies.
HYDROELECTRIC ENERGYEnergy from hydropower or water power,Usage
of the Earth's water cycle to generate electricity,High
precipitation levels and large elevation changes necessary to
generate significant quantities of electricity.
ALTERNATIVE ENERGY PLANTS IN SLOVENIAHydroelectric plants such
as Blanca, Botjan, Maribor, Medvode, Moste, and Vrhovo.
HYDROELECTRIC PLANT MARIBORLargest Slovenian producer of
electric power using renewable resources,Generating 25,5 % of
electric power in Slovenia,80 % of Slovenias electric power using
renewable energy sources,Electric power generated in an
environmentally friendly manner.
HYDROELECTRIC ENERGY ADVANTAGESElectricity can be constantly
produced, once a dam is constructed,Dams designed to last
decades,Not producing any green house gases.
HYDROELECTRIC ENERGY DISADVANTAGESDams extremely expensive to
build,Dams must be built to a very high standard,People forcibly
removed so that hydro-power schemes can go ahead.
SOLVING PROBLEMSLimit the use of fossil fuels,Expand the usage
of alternative fuels,Slowing down the degradation of the
destruction of our atmosphere.
ENVIROMENTAL ISSUES IN SLOVENIAGreenhouse emissions caused by
traffic in decline since 2008,Biggest state investments focused on
state roads,Biofuels accounting for 2% in Slovenia,Air quality
problematic, as the biggest problems being nitrogen oxides and dust
particles.

History
JAMES BLYTHFirst attempt,1887,For the production of
hydrogen.
MODERN WIND TURBINESKuriant, Nordtank, and Bonus,20 30 KW

TODAY WIND TURBINESEnercon E-1268 MWOther3 MW
TYPES
WIND FARMSAlta Wind Energy Center (USA),1,320 MW
HOW IT WORKS
ADVANTAGESClean energy,Does not destroy the working
surfaces,Money back in 14 years,Lasts 25 years.
DISADVANTAGEsDanger to birds,Requires more conventional power
plants to address variability,Wind turbines are noisy.
FACTSIn 2010 all wind turbines generated 197 GW,Today they
generate 430 THW, which is 2.5% of global electrical energy
consumption,In the last five years, the annual growth of new plants
was 27.6 percent.
