RENEWABLE ENERGY
eTwinning PROJECT / 2014-2015 Greek team Teachers: Chatziathanasiadou Anastasia Kosarli Evangelia Paschaliori Stamatia
our team: we are from TURKEY - LITHUANIA - GREECE - SPAIN
The sources of energy are:
Inexaustible
• Sun • Wind • Waves
Renewable
• Water • Biomass
Non Renewable
• • • •
Coal Oil Natural Gas Uranium
Renewable sources of energy are: Ηλιακή ενέργεια Υδροηλεκτρική ενέργεια
Βιομάζα
Γεω θερμική ενέργεια
Αιολική ενέργεια
Solar Energy • With the term “Solar Energy” we characterize the total amount of different forms of energy that come from the sun. • The use of the sun as a source of energy has been known since ancient times.
Solar Energy Passive
Active
Photovoltaic
Solar Systems
Solar Systems
Solar Systems
e.g. Bioclimatic design of buildings
e.g. Solar water heater
e.g. Solar panels
Wind Energy Wind Energy is the energy that comes from the movement of wind masses in the atmosphere. Its name in greek (aeoliki) comes from Aeolos who was the “administrator� of winds, according to Ancient Greeks. Sailing ships as well as windmills made use of the wind as an energy source thousands of years ago.
Wind Energy
Hydropower Energy Hydraulic Energy is the energy that is based on the exploitation and transformation of dynamic energy of the water in lakes and the kinetic energy of the water in rivers into electrical power. This transformation is achieved in two stages: • transformation of kinetic energy of the water into mechanical energy • transformation of mechanical energy into electrical (through the generator)
Hydropower Energy
Biomass
Biomass The term “biomass” is used to characterize any kind of material that comes from living organisms (like wood and other forest products, remaining of agricultural cultivations, animal waste, waste from food industries etc) and can be used as fuel for energy production.
biogas – biodiesel - bioaethanol .
In Greece, pellet is used as biomass fuel.
Geothermal Energy Geothermal Energy refers to earth’s natural thermal energy that comes from our planet’s hot inner past to the surface. • • • • • • • •
Production of electricity Heating buildings Cooling and air-conditioning Heating greenhouses and grounds Fish breeding Industrial applications like desalination of sea water Drying up agricultural products e.t.c. Thermal spa (for temperatures 25-40 °C
