Heat supply consumes particularly high amounts of energy
In 2018 about 69 terawatt hours (TWh) of final energy were consumed in the area of the Regional Authority FrankfurtRheinMain. Final energy is that part of the produced energy that reaches the consumer, for example in the form of fuels or electricity. A particularly large amount of energy is needed for heat. Overall, fossil energy sources prevail, the share of renewable energy is very low.
Final energy consumption: Most energy is needed to provide heat
More than one third (38 percent or ≈ 26 TWh) of the region's total final energy in 2018 was needed for the provision of heat. About 36 percent was used as fossil fuels for mobility (≈ 25 TWh/a) and 26 percent as electricity (≈ 18 TWh/a). Electricity consumption also includes electricity for heat generation and mobility. The high shares of heat and fuels for mobility in total energy consumption make it clear that heating and mobility are extremely important for the energy transition.
Where is electricity consumed?
Total electricity consumption was around 13 TWh/a in 2018. With 41 percent, the industry sector consumed the most electricity in 2018 (≈ 5.5 TWh/a). The commercial, trade, and services sector followed in second place with about 32 percent (≈ 4.3 TWh/a). Households consumed 25 percent (≈ 3.4 TWh/a) of total electricity consumption. Public facilities had the smallest share of electricity consumption with about 3 percent (≈ 0.3 TWh/a).
Where is heat consumed?
For heat consumption (≈ 26 TWh/a), the share of the individual sectors is distributed somewhat differently: With 45 percent, the household sector consumed the most heat in 2018 (≈ 11.7 TWh/a). Industry followed in second place with 35 percent (≈ 9.1 TWh/a). The high share of the industry sector is particularly due to consumption for process heat. The commercial, trade, and services sector had a share of 19 percent (≈ 5.0 TWh/a) of total heat consumption. Public facilities including infrastructure had the smallest share of heat consumption with around 2 percent (≈ 0.6 TWh/a).
Private transport consumes more than half of the energy of the entire mobility sector
The largest energy consumer in the mobility sector was motorised private transport, which accounted for more than half of total consumption (≈ 15 TWh/a). This was followed by freight transport (≈ 7 TWh/a) with 23 percent and local public transport (≈ 6 TWh/a) with 21 percent. Long-distance passenger transport accounted for 4 percent (≈ 1 TWh/a) of total energy consumption. Passenger air transport accounted for 0.5 percent of energy consumption in the region (≈ 0.1 TWh/a).
More than 80 percent of the energy consumed by the mobility sector comes from fossil fuels
The mobility sector is dominated by fossil fuels - more than 80 percent of energy consumption in 2018 was based on them. The most widely used fuel, diesel, accounted for around 46 percent (≈ 13 TWh/a). Gasoline followed closely behind with 34 percent (≈ 10 TWh/a). Kerosene had a share of around 4 percent (≈ 1.3 TWh/a). LPG had the smallest share of all energy sources in energy consumption with about 0.4 percent (≈ 0.1 TWh/a). In 2018 around 15 percent of energy consumption (≈ 4 TWh/a) in the mobility sector was covered by electricity. Electricity is used to operate trams or electric vehicles.
Fossil fuels also dominate final energy consumption in the other four sectors
The four other sectors - households, industry, public institutions and trade, commerce and services - consumed around 40 TWh of final energy in 2018. As in the mobility sector, fossil energy sources dominate. At around 41 percent (≈ 17 TWh/a), natural gas was the most widely used energy source. It was followed by electricity with 34 percent (≈ 13 TWh/a). About 14 percent (≈ 6 TWh/a) was covered by coal (including domestic fuel) and oil. District heating (consisting of hot water) and district steam heating (consisting of higher-temperature steam) represented 8 percent (≈ 3 TWh/a) of consumption. The share indicated as "Other" includes less common energy sources, such as liquefied petroleum gas and accounted for 1.6 percent (≈0.6 TWh/a).. The share of locally generated energy from renewable energy sources has so far been very low at 0.9 percent (≈ 0.4 TWh/a).
More than 50 percent of final energy consumption comes from the fossil fuels coal, oil and natural gas alone. This does not include the share of district heating and steam generated from fossil fuels. Likewise, the share of electricity from the federal electricity mix, which is generated from fossil energies, is not considered.
Data basis on electricity and heat consumption
The information on electricity and heat consumption in the region has been compiled from the municipal energy profile for the Regional Authority FrankfurtRheinMain (as of 2018). You can find the profile as well as detailed data on the individual member municipalities and administrative districts under Municipal Energy Profiles and in the Climate-Energy-Atlas. When calculating the energy profiles, we are dependent on the availability of various third-party data, some of which are published with a delay of several years.
