Heat supply consumes particularly high amounts of energy
About 72 terawatt hours (TWh) of final energy were consumed in 2017 in the area of the Regional Authority FrankfurtRheinMain. Final energy is defined as that part of the energy produced that reaches the consumer, for example in the form of fuels or electricity. A particularly large amount of energy is consumed for heat. Overall, fossil energy sources dominate, the share of renewable energy is very low.
Final energy consumption: Most energy is needed to provide heat
Almost half (46 percent or ≈ 35 TWh) of the region's total final energy consumption in 2017 was accounted for by the provision of heat. About 29 percent was used for fossil fuels for mobility (≈ 22 TWh/a) and 25 percent as electricity (≈ 19 TWh/a). Electricity consumption also includes electricity for heat generation and electricity for mobility. The high shares of heat and fossil fuels for mobility in total energy consumption make it clear that, in addition to electricity generation, heat generation and fuels for mobility from renewable energy sources are very important for the energy transition.
Where is energy consumed?
With 35 percent, the mobility sector consumed the most energy in 2017 (≈ 26 TWh/a). Industry followed in second place with 29 percent (≈ 22 TWh/a). Households consumed 22 percent (≈ 16 TWh/a), the trade, commerce and services sector 13 percent (≈ 9.5 TWh/a) of final energy. Public institutions including infrastructure had the lowest share of final energy consumption at around 2 percent (≈ 1.5 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 (≈ 14 TWh/a). This was followed by freight transport (≈ 6 TWh/a) with 24 percent and local public transport (≈ 6 TWh/a) with 21 percent. Passenger air transport accounted for only 3 percent of energy consumption in the region (≈ 0.8 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 2017 was based on them. The most widely used fuel, diesel, accounted for around 45 percent (≈ 12 TWh/a). Gasoline followed closely behind with 35 percent (≈ 9 TWh/a). Kerosene had the lowest share of all energy sources in energy consumption at around 3.5 percent (≈ 0.9 TWh/a). Around 17 percent of the energy consumption (≈ 4 TWh/a) in the mobility sector was covered by electricity in 2017. 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 49 TWh of final energy in 2017. As in the mobility sector, fossil energy sources dominate. At around 37 percent (≈ 18 TWh/a), natural gas was the most widely used energy source. It was followed by electricity with 30 percent (≈ 14 TWh/a). District heating (consisting of hot water) and district steam (consisting of steam at higher temperatures) represented 14 percent (≈ 7 TWh/a) of consumption. Almost 13 percent (≈ 6 TWh/a) was covered by coal (including domestic fuel) and crude oil. The share indicated as "Other" includes less common energy sources, such as liquefied petroleum gas. The share of locally generated energy from renewable energy sources has so far been very low at 0.7 percent (≈ 0.4 TWh/a).
Almost 50 percent of the final energy consumption comes from the fossil energy sources coal, oil and natural gas alone. This does not include the share of district heating and district steam generated with fossil fuels and the share of fossil fuels in the German electricity mix in 2017.
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 2017). 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 about 2 years.
