An international research team at the Stanford University has published on September 2017 a study on the future 100% renewable energy.
According to this study, between now and 2050, 139 countries in the world among which Italy is also present, would have the potential to completely decarbonize (with a total renunciation of fossil fuels) by using 100% renewable energy.
The assessment of a “low carbon” future required a basic analysis for each of the 139 countries examined, of which the available renewable energy resources were evaluated in the number of wind, hydroelectric and solar plants (photovoltaic, thermal, concentration).
How are we moving to imagine and plan a decarbonized economy?
The industry is increasingly moving towards a conscious use of energy sources with strategies that are mainly based on three points:
- The adoption of renewable energies for the feeding of its offices and its machinery
- Making the infrastructures more efficient and able to make them work, with fewer resources
- Study methods of recovery and reuse of waste energy for the feeding of its offices to further decrease the final bill of kW/h needed for the operations.
This mix between the use of own sources and the improvement of the infrastructures does not entail benefits in terms of impact on the environment. By self-producing energy and minimizing external demand, the energy bill is significantly reduced and this is transmitted in terms of costs, or better savings, to client company.
In terms of costs for the society most of the initial costs would be needed to replace the existing energy, while the rest is an investment that will be repaid over time with the reduction of health and climate costs:
- the reduction of carbon emissions each year would reduce by 4 to 7 million the number of deaths related to pollution
- it would possible to contain the increase in temperatures below 1,5° Celsius compared to pre-industrial average.
In terms of benefits, many would be for Italy in terms of employment: the balance between jobs created in clean energy and places lost in traditional energy would lead to a surplus of 485 thousand new jobs.
