All countries must ensure sustainability and strengthen resilience while improving people’s health and welfare. For this reason, one of the needs remains for an accelerated path to meet global climate goals through the decarbonisation of our societies. Recently, the energy trends have confirmed the need to accelerate a reduction in CO2 emissions and Renewable Energy Sources (RES) are an enabling technology both to reach the goals and limit the rise in average global temperatures to 1.5 °C. As IRENA has estimated, RES, together with energy efficiency improving, could account for over 80% of the CO2 emission reductions needed. Despite this, RES-based solutions have not been explored to date with the rigor and urgency that is needed.
