Europe's largest passive house in timber construction is located in Lübeck. It serves as a new workplace for 430 employees of the local public utility company. According to the client, the timber construction method was no more expensive than a conventional mineral wet construction method - also because an intelligent fire protection concept meant that it was not necessary to clad the timber components.
One million electric cars are to be on the road in Germany by 2020, at least that's what the German government wants. Sales figures are still lagging behind expectations. In addition, important questions arise about the origin of electricity and raw materials. ZDF has devoted a report to these questions in the series "planet e" entitled "Electric cars - top or flop?" and also interviewed ifeu Heidelberg. The programme is available in the ZDF Mediathek until 28.1.2017.
In addition to important aspects of the environmental balance, the paper also discusses the App My eDrive which is currently being developed by ifeu and the ADAC Technical Centre with funding from the Federal Ministry for the Environment (BMUB).

Net public electricity generation reached a record share of 59.7 per cent in 2023. The share of the load was 57.1 per cent. This is the result of an analysis presented today by the Fraunhofer Institute for Solar Energy Systems ISE. New records were set for wind and solar power in 2023. In contrast, generation from lignite (-27 per cent) and hard coal (-35 per cent) fell sharply. Photovoltaics stood out in the expansion of generation capacity: at around 14 gigawatts, the expansion was in double digits for the first time and significantly exceeded the German government's statutory climate protection target. Source of the data is the platform energy-charts.info
Photovoltaic systems generated approx. 59.9 TWh in 2023, of which 53.5 TWh was fed into the public grid and 6.4 TWh was used for self-consumption. At around 9 TWh, June 2023 was the month with the highest solar power generation ever. The maximum solar output of 40.1 GW was reached on 7 July at 13:15, which corresponded to a 68% share of electricity generation. In 2023, the expansion of photovoltaics significantly exceeded the German government's targets: instead of the planned 9 gigawatts, 13.2 gigawatts were installed by November; according to preliminary data, this will be more than 14 gigawatts by the end of 2023. This is a sharp increase compared to 2022 (7.44 GW). This means that PV expansion in Germany has reached double digits for the first time.
The Hydropower increased from 17.5 TWh in 2022 to 20.5 TWh. The installed capacity of 4.94 GW has hardly changed compared to previous years.
The Biomass at 42.3 TWh was at the level of 2022 (42.2 TWh). The installed capacity is 9 GW.
In total, the renewable energies approx. 260 TWh in 2023, around 7.2 per cent more than in the previous year (242 TWh). The share of renewable energy generated in Germany in the load, i.e. the electricity mix that actually comes out of the socket, was 57.1 per cent compared to 50.2 per cent in 2022. In addition to net public electricity generation, total net electricity generation also includes in-house generation by industry and commerce, which is mainly generated using gas. The share of renewable energies in total net electricity generation, including the power plants of "businesses in the manufacturing, mining and quarrying sectors", is around 54.9 per cent (2022: 48.2 per cent).
The Load in the electricity grid totalled 457 TWh, around 26 TWh less than in 2022. Due to the high electricity prices and higher temperatures, electricity was probably saved significantly. The increase in self-consumption of solar power is also reducing the load. The load includes the electricity consumption and grid losses, but not the pumped-storage power consumption and the self-consumption of conventional power plants.
Sharp decline in coal-fired power
After German coal-fired power plants ramped up their production in 2022 - due to the outage of French nuclear power plants, but also due to the distortions in the electricity market caused by the war in Ukraine - their share fell significantly in 2023. As a result, generation in November 2023 was 27 per cent below the same month in the previous year due to the drop in coal-fired electricity exports, but also because of the good wind conditions.
Overall, production from Lignite for public electricity consumption fell by around 27 per cent, from 105.9 to 77.5 TWh. This is in addition to 3.7 TWh for industrial own consumption. Gross electricity generation fell to the level of 1963.
Net production from Hard coal-fired power plants for public electricity consumption was 36.1 TWh (-35 per cent) and 0.7 TWh for industrial own consumption. It was 21.4 TWh lower than in 2022. Gross electricity generation fell to the level of 1955. Natural gas for electricity generation remained slightly below the previous year's level at 45.8 TWh for public electricity supply and 29.6 for industrial own consumption. Due to the shutdown of the last three nuclear power plants in Emsland, Neckarwestheim and Isar on 15 April 2023, the Nuclear power only contributed 6.72 TWh to electricity generation, which corresponds to a share of 1.5 per cent.
Battery storage systems are developing rapidly
The expansion of fluctuating renewable energies also increases the need for grid expansion and storage capacity. Battery storage systems, which are installed on a decentralised basis to buffer the generation of wind and solar power, are particularly suitable. The private household segment is showing strong growth, as is the case with photovoltaic systems. Overall, installed battery capacity almost doubled from 4.4 GW in 2022 to 7.6 GW in 2023, while storage capacity rose from 6.5 GWh to 11.2 GWh. The capacity of German pumped storage plants is around 6 GW.
Declining exports and exchange electricity prices
After an export surplus of 27.1 TWh was achieved in electricity trading in 2022, an import surplus of 11.7 TWh was recorded in 2023. This was due in particular to the lower electricity generation costs in neighbouring European countries in the summer and the high costs of CO2-certificates. The majority of imports came from Denmark (10.7 TWh), Norway (4.6 TWh) and Sweden (2.9 TWh). Germany exported electricity to Austria (5.8 TWh) and Luxembourg (3.6 TWh).
In winter, electricity exchange prices rose again and CO2-certificates became more favourable. This already led to a balance in November and, in conjunction with high wind power generation, to export surpluses in December. In contrast to its neighbouring countries (Austria, Switzerland, France), Germany also has sufficient power plant capacity in winter to produce electricity for export.
The average volume-weighted day-ahead price Exchange electricity price fell sharply to €92.29/MWh or 9.23 cents/kWh (2022: €230.57/MWh). This puts it back at the 2021 level.

The data basis
This first version of the annual evaluation takes into account all electricity generation data from the Leipzig electricity exchange EEX and the European Network of Transmission System Operators for Electricity (ENTSO-E) up to and including 31 December 2023. The quarter-hourly values from the EEX were energetically corrected using the available monthly data from the Federal Statistical Office on electricity generation up to September 2023. For the remaining months, the correction factors were estimated on the basis of past monthly and annual data. The extrapolated values from October to December are subject to larger tolerances.
This is based on the data for the German Net electricity generation to the public electricity supply. It is the difference between gross electricity generation and the power plants' own consumption and is fed into the public grid. The electricity industry calculates with net figures, e.g. for electricity trading and grid utilisation, and only net electricity generation is traded on the electricity exchanges. It represents the electricity mix that actually comes out of the socket at home.
According to the head of the EIB (European Investment Bank), Werner Hoyer, it is realistic to invest one trillion euros for climate protection within 10 years. In an interview with Der Spiegel, Hoyer said: "If we want to achieve our climate protection goals, we're no longer talking about billions, but trillions of euros" and "We can handle that." EU Commission President Ursula von der Leyen had named the climate protection target when she took office. Hoyer assumes that 1 trillion euro EU climate protection measures will trigger investments totalling 4 trillion euro.
Hoyer wants to mobilise additional money on the capital markets. "If we want to finance climate projects worth an average of 100 billion euros per year and the leverage that our investments trigger is around three, then the EIB would have to raise 30 to 35 billion euros per year," the bank boss told Der Spiegel. Already today, 28 per cent of the EIB's loans flow into projects that serve climate protection: "I want it to become 50 per cent in the future".
The EU target of investing 100 billion per year in climate protection was announced by the new head of the EU Commission Ursula von der Leyen at the 25th Climate Conference COP25 in Madrid. The EU is to become climate neutral by 2050. The EU's first climate protection law will be presented in March 2020.
