energia rinnovabili

1. Renewable energy in Italy: what kinds are out there, how much is produced, and how widespread is it

2. Natural electricity…

3. disadvantages Very difficult to get/capture (I don’t know when… Very difficult to manage (very high energy in small periods

4. So, Houston, we have a problem…

5. Meanwhile, in Italy… We are working to get a better world And also reduce the energy independence…

6. Our renewal energy Water (rivers) Wind Sun Geothermal Waste/disposables Waves

7. Over a third of the electricity produced in Italy comes from green sources: hydroelectric power has always dominated, followed by solar photovoltaic, bioenergy , wind power, and geothermal. Overall, Italy is Europe’s third largest producer of renewables .

8. Rivers (Dams) We call it “white gold” (opposite to “black gold” from petroleum)

9. When it comes to  renewable energy ,  Italy   has always been at the cutting edge in Europe and the world. The alternatives to fossil fuels, in fact, represent an important share of the country’s energy production , with a percentage that is  increasing constantly  year after year .

10. Water, the sun, the wind, and heat from the earth represent the main energy sources in question. Alongside these strategic resources, although to a much lesser degree, are other sources such as wave and tidal power, in addition to various biofuels .

11. Italy richer and healthier with renewables

12. 13 Wind energy in Italy The answer is blowin ’ in the wind …

13. 14 SITUATION Wind power in Italy is experiencing progressive growth in absolute terms. Despite developing at a slightly slower pace than other European countries and the continental average, we already have more than 5,000 plants spread across the country . Forecasts predict that the total energy obtainable from Italian wind power could double within a decade compared to the current 20 terawatt-hours a year, with an increase in maximum deliverable power of 11 to 19 gigawatts . It is estimated that, at global level, the capacity to harness the power of the wind will increase 15-fold between now and 2040; this will enable wind power to become on average the worldwide number one renewable source available to humanity.

14. 15 History of Wind Energy in Italy In Italy the activities on wind energy began in the early 80s. The main difficulty in the expansion of wind power in Italy is linked to its geographical position, because the significant presence of both mountain ranges and masses of water, leads to a different pattern of winds during the year . However , Italy can exploit winds of good intensity , especially in Mediterranean areas and islands . It is precisely in these areas , especially along the Apennine chain and coastal areas of south-central regions (Campania, Puglia, Molise, Sicily and Sardinia ), that the so-called wind farms were implanted . The first prototype of the generator was installed in Sardinia in 1989. Today after 23 years , there is a significant number of wind farms .

15. 16 WIND ENERGY FUTURE The increasing development of wind farms is linked to various factors , the most important being the realization that burning of fossil fuels generates pollutants harmful to humans and the environment . Consider that for the production of 1 kWh a conventional power plant emits 1000 g of carbon dioxide , 1.4 g of sulfur dioxide and 1.9 g of nitrogen oxides , while wind farm emissions are enormously reduced

16. 17 For the future it is expected , therefore , an exponential increase in the number of wind turbines , that means the construction of about 5000 medium size turbines , especially for off-shore wind farms .

24. 41% of the electrical energy in the island, is from this two power plants!!!

25. Waste/disposables Burning the remains from woods (leaves and others) Burning the remains from the paper industry (shells from trees) Burning waste/garbage from our houses Disposables from pigs industry ( faeces ) or lanfills , by decomposing in to methane and burning this gas.

26. Remains from woods (MORTÁGUA) 9 MW (63 GWh / year )

27. Burning the remains from the paper industry (CONSTÂNCIA)
