PV Magazine writes that EU countries will have to install 100GW of solar and wind power every year to achieve this target and the heating and transport industries are among those that need expand the use of renewables the most.

For buildings, EU officials say that 49% of the heating requirements for new buildings must come from renewable sources, with the share going up by 0.8% every year until 2025 and by 1.1% after that.

As far as the transport sector is concerned, with the wider adoption of EVs on the bloc, renewable energy must now account for 29% of the total power supply, rather than the previous 14%. An important mention here is the fact that e-fuels made from nuclear power plants-derived power will not count towards the goal.

Next in the talks was hydrogen, and it was stated by representatives that, by the next decade, 42% of this gas used within the EU has to be the "green" variation and by 2035, green hydrogen must account for 60% of the total amount of hydrogen used in the EU.

Green hydrogen is hydrogen made through the process of electrolysis and the energy required for the process has to come from renewables, such as solar and wind power.

There is another catch in this department, however. Green hydrogen production must source its clean energy requirements from local sources, so energy imports from afar are not an option.
