What are Germany and Japan doing differently in their energy  and climate policies, compared with the US, and how has this affected  their mix of energy sources used?
Do you believe Germany and Japan should be working toward a  common objective of energy transition away from fossil fuels? Why or why  not?

Notably, Japan and Germany are rethinking how their countries consume  energy and now these countries are taking steps in adopting a green  renewable energy policy.  Furthermore, the Fukushima nuclear disaster in  2011, displays how alternative energies should be a requirement. In  addition, it presented the dilapidation and the vulnerability of   Japans energy infrastructure.
Thus, the commonality with both countries is that the citizenry has  strongly opposed the use of nuclear power plants to power the electric  grid. Resulting, in a framework of renewable energy to modernize Japan  and Germanys’ energy grid for sustainable and environmentally safe  energy.  Specifically, Germanys Energiewende is an ambitious plan to  transition at least 50 % of Germanys electricity grids from fossil fuels to renewable alternative energy.
Germanys Energiewende has positive results such as emissions dropping to 2009 levels. Nevertheless, the cost and unpredictable weather are still  present-day issues. However,  the public and politicians still find  Energiewende very popular and beneficial to the environment.
 According to The Japan Times (2015), Energiewende has been a  courageous move: The German government has begun out with, a parcel of  questions and the choice to shut down atomic plants reorganized the deck  in erratic ways. Energy companies have endured; final year, E.ON, the  countrys greatest control provider, posted a net misfortune of ‚¬3.2  billion, the greatest in its history, and chosen to part it in two, one portion centering on renewables  and the other on fossil fuels. However, its clear presently that the  program has been a victory which as long as there are a well-defined  objective and a decided exertion to reach it, the fundamental innovation  will display itself.
Incidentally, the US has not and will not in the near future  implement public policy that converts half of the energy grid with  renewable energy sources.  In light of the fact, the fossil fuel  industry has a hold/influence on many sectors of American society. 
Overall,  it is fantastic that Germany and Japan are working together  to create a partnership to reduce their countries’ carbon footprint.  Essentially, since the Paris agreement, each country has benefited from  the exchange in the flow of ideas regarding the expansion of renewable energies. Hence, this partnership between Japan and Germany can serve as a blueprint for other countries to follow.
Given that the two countries have stressed the central role of  sustainable energy in light of the Paris Agreement, the Energy  Partnership benefits both parties. Germany has extensive experience in  the expansion and system integration of renewables, whereas Japan has  been a pioneer in the use of hydrogen as well as in the development of  energy storage and so-called smart grids (Adelphi, 2019).
