ENERGY NOT CONSIDERED IN THE PIE CHART
Grid losses (transport and distribution losses): the amounts
- f energy that are not paid for by users.
The difference between what be generated and what be distributed.
T&D Losses = (Energy Input to feeder (Kwh) – Billed Energy to Consumer (Kwh)) / Energy Input kwh x 100
Own consumption: the total energy needed from the power plants to run up the electricity necessary for the consumers. All together, grid losses, own consumption and the energy
- f the different technologies made the energy produced by
the country.

NUCLEAR POWER
From 1966, 4 nuclear power plants 1° referendum, 1987 to abolish the use

CML2001 - Apr. 2013, Global Warming Potential, excl biogenic carbon (GWP 100 years) [kg CO2-Equiv.]
- Biogenic CO2 emissions are defined as “non - fossilized and biodegradable organic material originating from plants, animals, or
microorganisms “
- Biogas from 0,207 to 0,401
- GWPs have the highest technologies based on carbon dioxide, methane and CFCs: coal gasses, hard coal, HOF, lignite, natural gas and
- waste. T

FRESHWATER AQUATIC ECOTOXICITY POTENTIAL
- Industries produce large amount of materials and energy that negatively influence water.
- Industries warm water.
- Crops for use as biomass--> in areas dedicated to irrigation, problems of water pollution can also arise as a result of soil and nutrient runoff (eutrophication of the
water).
- And if we talk about the industrial discharge we have to say that 25 percent of Italy's wastewater flows into the sea, lakes and rivers without proper purification.

CONCLUSION
- Sustainable development is vital for the evolution of generations, and the energy sector, having a
major contribution to it, should be effectively assessed and managed to accomplish the fruits of sustainable electricity production.
- Comparing the individual sources of electricity generation with respect to considered sustainability
indicators, hydropower is the most preferred source due to the lowest environmental impacts. It is further revealed that heavy fuel oil is the worst option for capital investment in Italy.
- Overall in five environmental indicators, heavy fuel oil, biogas and biomass is the worst option for
electricity generation and is advisable to minimize this kind of sources in energy mixes.
- Hydropower, wind power and geothermal technology impose the least impact on economic and
