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 biomassLiquid fuels from

biomass (bioethanol, biodiesel)

Types of biomassBiogas

Biomass use

Heating

Biomass use

Electricity production

Biomass use

Vehicle fuel

ENERGY FROM WASTE

SOLAR ENERGY

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.
