The implementation of this strategy will allow a gradual but significant evolution of the system and the overcoming of the European 20-20-20 objectives, with the following results expected in 2020: National Energy Society: for Summary of key messages more competitive and sustainable energy Containment of consumption and evolution of the mix in favor of renewable sources. In particular, a 24% reduction in primary consumption is expected compared to the inertial trend in 2020 (i.e. -4% compared to 2010), exceeding the European reduction targets by 20%, mainly thanks to energy efficiency actions. In terms of mix, a 19-20% incidence of renewable energy on gross final consumption is expected (compared to around 10% in 2010). On primary energy consumption the incidence is equal to 23%, while there is a reduction from 86 to 76% of fossil fuels. Furthermore, renewables are expected to reach or exceed the levels of gas as a source in the electricity sector, representing approximately 35-38% of consumption (compared to 23% in 2010).  Significant reduction in energy costs and progressive alignment of wholesale prices to European levels. In particular, it is possible to save about 9 billion euros a year on the national electricity and gas bill (today equal to about 70 billion). This is the result of about 4-5 billion a year of additional costs compared to 2012, and about 13.5 billion a year of savings, including both a reduction in prices (assuming constant international prices) and a reduction in prices. volumes (with respect to an inertial reference scenario). Achievement and exceedance of all European environmental objectives by 2020. These include both the aforementioned targets for the consumption of renewable energy and energy efficiency, and a reduction of greenhouse gas emissions equal to 21%, exceeding the European objectives for Italy, ETS and others, quantifiable in an 18% reduction compared to 2005 emissions, in line with the national CO reduction plan. [Greater safety, less dependence on supply and greater system flexibility. A reduction in the foreign energy bill of around  14 billion per year is expected (compared to the current 62 billion, and -19 compared to the 2020 trend imports assuming constant commodity prices), with a reduction from 84 to 67% dependence on foreign countries, thanks to energy efficiency, increased production of
