The second E of the strategy focuses on the use of renewable energy sources, such as photovoltaics, water, and wind. Important to note is that economic as well as ecological aspects must be taken into consideration when using renew-able energy sources.
Electricity as the backbone of the energy system
The newcomer to the 3-E strategy constitutes the third E: electrification. Accord-ing to ETH Zurich researchers, in future C02 poor electricity will establish itself as the backbone of a sustainable energy system. It is increasingly being used in heating and cooling buildings (with heat pumps, for example), and is expected to extend to individual mobility (moving, in the long run, from hybrid vehicles to fully electric cars).
A reorientation of the energy system, however, will not happen overnight. It is likely to take several decades. All the more reason that it is crucial that steps be taken today: infrastructure in industrialized countries (transmission network, power plants) needs to be renewed and in threshold countries, erected.
Innovative research at ETH Zurich
ETH Zurich conducts intensive research with a mind to finding new solutions and methods to face the CO2 problem. Professor Marco Mazzotti from the Insti-tute for Process Engineering is researching the possibilities of eliminating CO2 in fossil-fueled power stations and combining it with stable and solid substances. This so-called mineralization thus facilitates the permanent and secure storage of greenhouse gases. Power electronics are becoming increasingly smaller and more efficient: the research group headed by Professor Johann Kolar from the Power Electronic Systems Laboratory is devoted to developing such compo-nents that are deployed, for example, in hybrid vehicles. Efficient control of the drive system of such cars makes a significant contribution towards environmen-tally-friendly private transport. <
