100 Renewables for Electricity and Heat - a Holistic Model for a Future German Energy System - (PPT)

摘要

100% renewable energies for electricity and heat possible; Wind Offshore 75…85 GW (technical potential 85 GW); Wind Onshore 170…200 GW (technical potential 200 GW) → factor 6…7 of Today; Photovoltaics: 170…250 GW → factor 6…8 of today; Solar thermal: 100…250 GW → factor 10…25 of today; Areas needed for solar technologies approx. 1200 to 1800 km~2 (technical potential >2800 km~2); Building energy retrofit: heating energy reduction by 50…60%; Total annual cost in the range of 118…126 billion for well dimensioned overall systems; Total annual cost in same range as cost of Germanys energy system of today (approx. 120 billion for electricity and heat).
