Ny rapport om energiomlegging

I dag presenterer European Renewable Energy Council og Greenpeace en ny rapport med tittelen: TOWARDS A FULLY RENEWABLE ENERGY SUPPLY IN THE EU 27


Lagt ut 09/07-2010

Som tittelen antyder tar rapporten seg hvordan EU kan legge om energiforbruket fra dagens fossile regime til et 100% fornybart energiforbruk. Rapporten angir 6 punkter for å få dette til: 1. Exploitation of the large existing energy efficiency potential will ensure that primary energy demand is reduced by more than a third, from the current 73,880 PJ/a (2007) to 46,030 PJ/a in 2050, compared to 75,920 PJ/a in the Reference scenario. This dramatic reduction is a crucial prerequisite for achieving a significant share of renewable energy sources in the overall energy supply system, compensating for the phasing out of nuclear energy and reducing the consumption of fossil fuels. 2. Electric vehicles pick up in the transport sector and hydrogen produced from electrolysis plays an increasingly important role. After 2020, the final energy share of electric vehicles increases to 14% by 2030 and to 62% by 2050. More public transport systems also use electricity and there is a greater shift in transporting freight from road to rail. With biomass mainly committed to stationary applications for heat and power generation, the production of biofuels is limited by the availability of sustainable raw materials. 3. The increased use of CHP generation additionally improves the supply system’s energy conversion efficiency, increasingly using natural gas and biomass. In the long term, improved energy efficiency and a decreasing demand for heat, as well as a large potential for producing heat directly from renewable energy sources, limits the further expansion of CHP. 4. The electricity sector will be the pioneer of renewable energy utilisation. By 2050, around 97% of electricity will be produced from renewable sources. A capacity of 1,520 GW will produce 4,110 TWh of renewable electricity per year by 2050. A significant share of the fluctuating power generation from wind and solar photovoltaics will be used to supply electricity for vehicle batteries and produce hydrogen as a secondary fuel in transport and industry. By using load management strategies, excess electricity generation will be reduced and more balancing power made available. 5. In the heat supply sector, the contribution of renewables will increase to 92% by 2050. Fossil fuels will be increasingly replaced by more efficient modern technologies, in particular biomass, solar collectors and geothermal. Geothermal heat pumps and solar thermal power will play a growing part in industrial heat production. 6. By 2050, 92% of final energy demand will be covered by renewable energy sources. To achieve an economically attractive growth of these sources, a balanced and timely mobilisation of all technologies is of great importance. Such mobilisation depends on technical potentials, actual costs, cost reduction potentials and technical maturity. Småkraftforeninga synes rapporten er interessant, men er forsåvidt kun nok en rapport i en uendelig rekke av rapporter og utredninger. Det som likevel skiller denne rapporten fra mange andre er at den kobler omleggingen opp mot ny økonomisk vekst og er sånn sett mer troverdig og gjennomførbar enn andre rapporter.
