ALTERNATIVE ENERGY

What is alternative energy?  From permanent natural processes,  Reliable,  Main feature:  permanence and high energy potential,  Most of it comes from solar radiation.

Renewable energy in Slovenia

Types of alternative energy

HYDROENERGY

Energy production  All the water hydropower is being generated in the generator powered by a water turbine.  Water is supplied to the turbines which power a generator that converts the hydropower to electricity.

Types of hydroelectric power plants  Flowing power plant  Pumped storage power plant  Power plants for tide and wave energy extraction

The Francis Water Turbine - simulation

Pumped storage power plant AVČE

BIOMASS

 The biological material derived from the living or recently living organisms.  The decomposed organic material that is exploited as an energy source.  It is constantly produced during the photosynthesis. What is biomass ?

Types of biomass  Hard biomass (briquettes, wood chips, pellets)

Types of biomass  Liquid fuels from biomass (bioethanol, biodiesel)

Types of biomass  Biogas

Biomass use  Heating

Biomass use  Electricity production

Biomass use  Vehicle fuel

ENERGY FROM WASTE

What is solar energy?

 Passively (heating living areas through glass surfaces)  Actively :  building and sanitation water heating  generation of electricity  building cooling Uses of solar energy in buildings

WIND ENERGY

Wind Wind energy

Wind turbines convert kinetic energy of the air (wind) into work and then into electric energy

GEOTHERMAL ENERGY

 Produced and saved in the Earth‘s interior  We use it directly from the warm water vents, steam vents or by cooling hot stones.  In Slovenia 79 wells.
