Comprehensive Overview of Energy Balances in Germany

Slide Note

This material covers various aspects of energy balances in Germany, including components of energy flowcharts, renewable energy sources in the German energy balance, and total final consumption of road transport energy. It provides a detailed analysis of energy imports, domestic extraction, losses, and useful energy consumption across different sectors. Additionally, the content explores the share of renewable energy sources in total electricity output and energy balances from 2010 to 2017 based on the AGEB reports.

Question 2: RES in German energy balance Energy balances of Germany 2017 (AGEB) PJ 2.353.457 769.673 32,7% TWh 653.738 213.798 Cell AD39 AD33 Total electricity output Hydro, wind, PV and other RES share in total output TPES RES in TPES 13.522.990 1.797.459 3.756.386 AI15 499.294 SUM(Z15: AB15) RES share in TPES 13,29% Avr efficiency of RES power pl.: 769.673 PJ / 1.797.459 PJ = 42% But: Hydro, wind and PV cannot be separated from biomass and renewable waste.

Question 2: RES in German energy balance (continued) IEA Atlas of Energy: Germany Electricity generation (TWh) RES generation (TWh) RES share in electricity (%) RES share in TPES (%) 647,7 216 33,0 13,0 AGEB uses IEA method to account for RES in TPES. But: these is a slight discrepancy in RES generation (in TWh). Apart from Hydro, wind, PV and other , the German energy balances list Industrial power stations (lines 19 and 13), part of which may be based on RES. Seite 6

Question 10: TFC of road transport Energy balances of Germany 2010 and 2017 (AGEB) PJ Motor gasoline Diesel oil LPG Natural gas Biomass & ren. wastes Electricity Total 2010 791.416 1.168.063 21.823 8.768 119.371 2017 719.580 1.425.424 15.377 5.848 108.349 - 2.109.441 565 2.275.144 See line 69 Road transport Seite 7
