2. It is true that we need energy in our everyday life… It is also true that we use A LOT of energy in our everyday life… because of this attitude the supplies of energy seem to decrease dramatically and Earth, our «home», suffers…

8. Photovoltaic parks Not only single homeowners, but also communities select the photovoltaic panels for the production of the electricity needed in the area. Smaller or bigger photovoltaic parks can be found in towns, in villages, up in the mountains or near a sea… wherever sun shines!

9. Solar water heater The solar water heaters use the sun power to heat water in the boilers found on the top of the heater or somewhere in the house. The water can be kept hot in there for a long time. As long as the day is sunny, in winter or in summer, there will be hot water in the house. The solar water heater is an economical solution and very friendly to the environment.

10. more use of thefor the commonweal photovoltaic panels on the top of the bus stations produce enough electric power to make lights and information boards work… street lamps are using electric power produced by tiny photovoltaic panels that are on their top…

14. Fireplace A fireplace is an architectural structure made of brick, stone or metal designed to contain a fire. Historically it was used for  heating a room  cooking  heating water  or even enlighten a room In addition to all its advantages we should mention  the pleasure of a family gathering around the fire  the geniality  or the romantic atmosphere

15. ENERGY FIREPLACE The energy fireplace is an even more economical solution. It has efficiency It doesn’t need a lot of wood It can heat a whole house thanks to its piping It doesn’t pollute the environment

17. Except from wood itself, several other materials that come directly or indirectly from the plants’ world can be used for the production of energy (electric power & heat) and biofuels through different procedures. Those materials consist the biomass and the energy produced is called bioenergy. from biomass to bioenergy procedures & biofuels

19. Wind turbine The movement of the wind (wind energy ) is converted into electricity by wind turbines. The wind turns the turbine blades, which spin a motor which generates the current. The electric power can be fed directly to the main power network stored in batteries heat water

20. wind turbines for home use

21. wind turbines parks In well chosen areas, where the wind blows hard, the state places a large number of wind turbines that are capable of producing enough electric power to cover the area ‘s needs in electricity. Wind turbines sea parks

22. Traditional Windmills water pumping windmill weathervane

25. Water is often used at home not exactly as an energy source, but as the mean for the thermal energy (heat) to be transferred all over the house. Through the radiators’ piping the running water is the one responsible to keep every room warm!

26. Traditional «machines» working by hydropower A traditional washing machine for heavy fabrics or carpets (!) and a water saw for the cutting of huge trees’ trunks are two old mechanisms which take advantage of the high pressure of falling water.

27. Watermills all over the world are the simplest proof that the renewable sources of energy were always part of everyday life.

29. Geothermal power plants Geothermal energy is thermal energy generated and stored in the Earth, it is Earth's internal heat. All geothermal power plants basically convert heat to electricity. They use steam (dry steam from below ground or steam produced by super- hot water) to turn large turbines, which run electrical generators. Geothermal power is cost effective reliable sustainable and environmentally friendly

30. residential geothermal heat pump A geothermal heat pump is a central heating and cooling system that transfers heat from or to the ground. It uses the earth as a heat source (in the winter) or a heat sink (in the summer).

31. Statistics The EU's Renewable energy directive sets a binding target of 20% final energy consumption from renewable sources by 2020. They are also each required to have at least 10% of their transport fuels come from renewable sources by 2020. All EU countries have adopted national renewable energy action plans showing what actions they intend to take to meet their renewables targets. These plans include sectorial targets for electricity, heating - cooling and transport. Every two years, the EU publishes a renewable energy progress report. In 2014, the projected share of renewable energy in the gross final energy consumption is 15.3% ( 2012 => 14,1% … 2005=> 8,7% ). The latest report from 2015 states that 25 EU countries are expected to meet their 2013/2014 interim renewable energy targets…
