Energy in Italy comes mostly from fossil fuels. Among the most used resources are petroleum (mostly used for the transport sector), natural gas (used for electric energy production and heating), coal and renewables. Italy has few energy resources, and most supplies are imported.[1]

An important share of its electricity is imported, mainly from Switzerland and France. The share of primary energy dedicated to electricity production is above 35%,[2] and has grown steadily since the 1970s.

Electricity is produced mainly from natural gas, which accounts for the source of more than half of the total final electric energy produced. Another important source is hydroelectric power, which was practically the only source of electricity until 1960. Wind and solar power grew rapidly between 2010 and 2013 thanks to high incentives. Italy is one of the world's largest producers of renewable energy.[3]

Energy in Italy come mostly from fossil fuels. Among the most used resources are petroleum (mostly used for the transport sector), natural gas (used for electric energy production and heating), coal and renewables. Electricity is produced mainly from natural gas, which accounts for the source of more than half of the total final electric energy produced. Another important source is hydroelectric power, which was practically the only source of electricity until 1960. The first power plant in continental Europe was inaugurated in Milan in 1883.[5]

Eni, with operations in 79 countries, is considered one of the seven "Supermajor" oil companies in the world, and one of the world's largest industrial companies.[6] The Val d'Agri area, Basilicata, hosts the largest onshore hydrocarbon field in Europe.[7] Moderate natural gas reserves, mainly in the Po Valley and offshore Adriatic Sea, have been discovered in recent years and constitute an important mineral resource.[8]

Solar panels in Piombino, Tuscany. Italy is one of the world's largest producers of renewable energy.[3]

In the last decade, Italy has become one of the world's largest producers of renewable energy, ranking as the second largest producer in the European Union and the ninth in the world. Wind power, hydroelectricity, and geothermal power are also important sources of electricity in the country. Italy was the first country in the world to exploit geothermal energy to produce electricity.[9] The first Italian geothermal power plant was built in Tuscany, which is where all currently active geothermal plants in Italy are located. In 2014 the geothermal production was 5.92 TWh.[10]

Solar energy production alone accounted for almost 9% of the total electric production in the country in 2014, making Italy the country with the highest contribution from solar energy in the world.[3] The Montalto di Castro Photovoltaic Power Station, completed in 2010, is the largest photovoltaic power station in Italy with 85 MW. Other examples of large PV plants in Italy are San Bellino (70.6 MW), Cellino san Marco (42.7 MW) and Sant’ Alberto (34.6 MW).[11]

Renewable sources account for the 27.5% of all electricity produced in Italy, with hydro alone reaching 12.6%, followed by solar at 5.7%, wind at 4.1%, bioenergy at 3.5%, and geothermal at 1.6%.[12] The rest of the national demand is covered by fossil fuels (38.2% natural gas, 13% coal, 8.4% oil) and by imports.[12]

Italy has managed four nuclear reactors until the 1980s, but in 1987, after the Chernobyl disaster, a large majority of Italians passed a referendum opting for phasing out nuclear power in Italy. The government responded by closing existing nuclear power plants and stopping work on projects underway, continuing to work to the nuclear energy program abroad instead. The national power company Enel operates seven nuclear reactors in Spain (through Endesa) and four in Slovakia (through Slovenské elektrárne),[13] and in 2005 made an agreement with Électricité de France for a nuclear reactor in France.[14] With these agreements, Italy has managed to access nuclear power and direct involvement in design, construction, and operation of the plants without placing reactors on Italian territory.[14]

Energy resources

Reserves

Italy's fossil fuel reserves are modest, but its renewable energy potential is significant, especially for hydro and solar.

  • proven and economically recoverable oil reserves are estimated at the end of 2017 at 78 Mt, and additional potential resources at 1,540 Mt; cumulative production up to 2017 reached 205 Mt: Italy has therefore already largely depleted its resources; at the rate of current production (4.1 Mt in 2017), the reserves would be exhausted in 19 years;[24]
  • proven and economically recoverable gas reserves are estimated at the end of 2017 at 38 Gm3, and additional potential resources at 405 Gm3; cumulative production up to 2017 reached 766 Gm3: Italy has therefore also largely depleted its resources there; at the rate of current production (5.4 bcm in 2017), proven reserves would be exhausted in 7 years;[24]
  • for coal, Italy has only 10 Mt of reserves.[24]

Italy benefits from significant hydroelectric potential, particularly in the Alps, but it is already almost fully exploited; During the first half of the 20th century, hydroelectricity covered almost all of the country's electricity needs.

The map of solar radiation in Italy reveals high potentials in southern Italy, particularly in Sicily and Sardinia.

National energy production

In 2018, the country's energy production reached 43.42 Mtoe, up 10.9% compared to 2017, broken down into:[25]

  • fossil fuels: 21.6%, of which:
    • natural gas: 4.46 Mtoe (10.3%), covering 7.5% of domestic gas consumption;
    • oil: 4.68 Mtoe (10.8%), 8% of oil consumption;
    • coal: 0.25 Mtoe (0.6%), 2.7% of coal consumption;
  • renewable energies: 34.02 Mtoe, i.e. 78.4%.

All of these resources covered only 25.2% of the country's needs.[25]

Imported energy

Italy depends on its imports for a very high share of its energy needs: in 2018, its energy imports reached 158.51 Mtoe against 163.46 Mtoe in 2017; after deducting 31.09 Mtoe of exports (mainly petroleum products), net imports represented 74.0% of the country's total energy consumption, while its national production only covered 25.2% of his needs.[25]

Oil is the main imported energy: in 2018, net imports of oil and oil products reached 51.97 Mt, i.e. 88.7% of the country's domestic oil consumption.[25] The 11 refineries in operation in 2018 have a refining capacity of 83.7 Mt/year, down 2.7% compared to 2017. The Venice biorefinery, the world's first refinery converted to vegetable sources in 2014, has a biodiesel production capacity of 360,000 tonnes /year from used cooking oils and palm oil; this capacity will be increased to 420,000 tonnes/year in 2021, to which will be added the Gela biorefinery (600,000 tonnes/year).[26]

Natural gas is the second most imported energy: in 2018, net imports of natural gas reached 53.27 Mtoe, or 92.9% of the country's gas consumption.[25]

Italy also imported 9.23 Mtoe of coal in 2018, mainly for power plants, coke and heat production plants.[25]

Even electricity is largely imported: 9.66 Mtoe in 2018,[25] or 13% of total gross electricity supply.

Infrastructure

Refineries

Файл:SARAS 1.JPG
Refinery in Sarroch, Sardinia

The Priolo Gargallo complex, in Sicily, includes 2 refineries linked by pipelines: ISAB NORD and ISAB SUD, belonging to the Russian company Lukoil, with a total capacity of 16 Mt/year.[27]

The Sarroch refinery in Sardinia (capacity: 15 Mt/year), i.e. more than 20% of the country's refining capacity, belongs to SARAS (Società Anonima Raffinerie Sarde).[28]

In May 2018, the Algerian company Sonatrach bought from Esso (a 100% subsidiary of ExxonMobil) the Augusta refinery in Sicily (capacity: 9.5 Mt/year), three oil terminals located in Augusta, Naples and Palermo and their associated pipeline systems.[29]

The refineries of Porto Marghera, in Veneto, and Gela, in Sicily, have been converted into bio-refineries using as raw materials vegetable oils, waste (frying oil, fats, urban waste), algae, etc. ( 230,000 tonnes/year since 2014 in Porto Marghera, 750,000 tonnes/year since 2019 in Gela).[30]

Gas pipelines

Файл:Trans Adriatic Pipeline.png
Trans Adriatic Pipeline

Russian gas is transported to Italy via the Yamal–Europe pipeline, then the Trans Austria Gas Pipeline.

The Trans-Mediterranean Pipeline (or Enrico Mattei gas pipeline) transports gas from Algeria. Starting from Hassi R'Mel, it covers 550 km in Algerian territory, then 370 km in Tunisia, crosses the Mediterranean Sea by an underwater section of 155 km, then Sicily (340 km), the Strait of Messina, before going up the entire Italian peninsula, to join the gas network near Bologna.

The Greenstream pipeline, commissioned in 2004, the longest underwater gas pipeline in the Mediterranean Sea, connects western Libya to Sicily.

The Transitgas Pipeline, inaugurated in 2008, connects the gas market in northwestern Europe with Italy.[31]

The Trans Adriatic Pipeline project is a gas pipeline project transporting natural gas from the Caspian Sea (Azerbaijan) to the European market. It leaves from the Greek-Turkish border and crosses Greece, Albania and the Adriatic Sea to arrive in Italy.[32] Its construction was completed in October 2020 and its operation should begin in mid-November.[33]

Final energy consumption

Breakdown by source

Final energy consumption (after refining, transformation into electricity or district heating, transport, etc.) was 127.3 Mtoe in 2018, up 1.5% compared to 2017. It was divided into 73, 2% fossil fuels (1.7% coal, 41.8% oil, 29.7% natural gas), 7.0% thermal renewable energies and 19.8% electricity.[36] The production of electricity was split into 60.3% from fossil fuels and 39.7% from renewables; in total, final consumption was therefore 85% fossil fuel and 15% renewable.[37]

Electricity

Шаблон:Multiple image Шаблон:Main Шаблон:See also In 2014 Italy consumed 291.083 TWh (4,790 kWh/person) in electricity, consumption in household were 1057 kWh/person.[10] Italy is a net importer of electricity: the country imported 46,747.5 GWh and exported 3,031.1 GWh in 2014. Gross production in 2014 was 279.8 TWh. The main power sources are natural gas and hydroelectricity.[10]

Italy has no nuclear power since it was banished in 1987 by referendum. Italy was the first country to exploit geothermal energy to produce electricity.[9] The first Italian geothermal power plant was built in Tuscany, which is where all currently active geothermal plants in Italy are located. In 2014 the geothermal production was 5.92 TWh.[10]

District heating

Файл:Centrale elettrica moncalieri.jpg
The cogeneration plant of Moncalieri, which supplies heat to the district heating network of the metropolitan area of Turin[39]

District heating is widespread in central, eastern and northern Europe,[40] but since the early 1970s it has also begun to spread to Italy.[41] The first Italian city to adopt a district heating network was Brescia in 1972,[42] followed in 1982 by Turin, which since 2011 has the largest city district heating network in Italy and one of the largest in Europe,[43][44] while the Italian region that has the largest extension of the district heating network is Lombardy.[45]

The heat produced by cogeneration plants (94%) as well as by boiler rooms (6%) and distributed by district heating represented 174 PJ in 2019, or 3.5% of the country's final energy consumption, intended for 71% to industry, 21% to the residential sector and 7% to the tertiary sector.[15] It was produced in 2020 from coal for 2.7%, oil for 12.9%, natural gas for 63.1%, biomass for 15.6%, waste for 5.3% and geothermal energy for 0.4%. Production increased by 19% between 2005 and 2020.[21] Italy's heat production reached 231 PJ in 2019, i.e. 1.5% of the world total (10th in the world).[21]
