The further development and increased use of renewable energies and the substitution of fossil fuels contribute significantly to the reduction of GHG emissions. Therefore, the German federal government has adopted target percentages for energy consumption from renewable sources in the EEG.

The EEG sets the target that at least 80% of gross electricity consumption in Germany should come from renewable energies by 2030. To this end, the law provides for an expansion and electricity volume path that contains annual expansion targets. Furthermore, the EEG also provides that the integration of renewable energies into the existing electricity grid must have the highest priority, and that the expansion of the corresponding renewable energy plants is in the overriding public interest.

As described in "CO2 and Energy Targets", the GEG stipulates that 65% of the heat generated by newly installed heating systems must be produced from renewable energies or unavoidable waste heat. However, the law provides for numerous exceptions and transitional periods. For example, the obligation for new buildings outside of a new development area (Neubaugebiet) only applies from 2026.

In contrast, the Building Electromobility Infrastructure Act (Gebäude-Elektromobilitätsinfrastruktur-Gesetz or GEIG) does not set minimum percentages of energy consumption from renewable energies. However, it also imposes requirements on the building owners in terms of sustainability. According to the GEIG, newly constructed residential buildings with more than five parking spaces must equip these parking spaces with the infrastructure for recharging electric vehicles (EVs). For nonresidential buildings and in the case of renovations, similar, although less comprehensive, obligations to provide recharging infrastructure for EVs apply.
