As well known, world’s electric power industry is poised in a quite difficult situation at the moment, cause the huge investments needs to renew actual technology used. But difficulties exist also cause the coming era of carbon emission constraints, as electric utilities are world wide perceived as main responsible for climate change issues. Applying to each single European power plant the obligations foresee under EU Emission Trading Scheme, it means to explicitly declare that electric industry impacts in a absolute negative way on climate change issues. People and Institutions consequently ascribes to electric utilities about 40% of the world’s carbon dioxide emissions, due to the consumption of fossil sources. But this is not correct. Electricity is not an environment enemy, rather one its most important ally.  Misunderstanding came from an incomprehensible mistake in CO₂ allocation along electricity usage-chain, with all CO₂ emission allocated in generation step.Electricity generation step only transforms internal energy of fossil fuel into a new kind of energy, just electricity, making it possible to avoid analogous transformation of fossil fuel energy in some different places, where electricity is made available, via electric network. In these places, than, CO₂ emissions should be allocated. In a correct way of thinking, natural gas utilities, like for example Gas de France or ENI, are not considered responsible for CO₂ emissions produced burning gas at final point of usage. Company could be considered responsible for its inefficiency or for gas network leakage, but not for elsewhere consumptions.Electric utilities should be treated in a similar manner: both deliver energy, although in two different form. How much CO₂ emission should be correctly allocated in generation process and than ascribed to the electric utilities? Just the amount related to the power plant inefficiency, that is in Italy - for example - about 54%. The rest of whole CO₂ emissions, about 46%,  should be allocated in final electricity users, because over there you could find CO₂ emissions if electricity were not available.  Real contribution of electric industry to the CO₂ emissions is about half the amount at present is considered.
