This clip is presenting how, with a systemic approach, a country like Switzerland can become 100% driven by renewable energy and even have the possibility of becoming a carbon sink. The solutions are the use of heat pumps to heat buildings, the use of PV panels to drive heat pumps, the use of power to gas and cogeneration by fuel cells with CO2 capture to supply heat and electricity when the sun is not shining using the excess of electricity in the summer stored as natural gas. The biomass is used as a source of carbon  and heat for the  industry while the cogenerated fuel can be used in range extenders for the electrified mobility. By design the system has the possibility of separating the CO2 resulting from the biomass conversion and can therefore be sequestrated by mineralisation.
