The initiatives were agreed during a joint meeting of the countries' cabinet ministers last Thursday in a bid to "work even more closely together", German energy minister Brigitte Zypries said in a statement.
"I also made it clear that Fessenheim should be the first nuclear power plant to shut down," she added, referring to comments by French environment minister Nicolas Hulot earlier this month that France was planning to close up to 17 nuclear plants. Fessenheim, situated near the German border, is France's oldest nuclear power station.
The countries also agreed to set up a fellowship programme to support energy and climate research that will help to implement the Paris climate agreement.
With a budget of €45 million, the programme will provide funding for up to 50 scientists from around the world.
Berlin and Paris will also work closely together at EU level in the discussions on the 'clean energy package', tabled by the European Commission last November, the minister added.
