Anti-nuclear movement, helping the German economy go wrong

This week we have witnessed the incredible announcement by German Chancellor Angela Merkel saying Germany will abandon nuclear power totally by 2022, when it will shut down the last 3 remaining nuclear plants that will be in service on that date. Germany has a total of 9 nuclear plants providing energy to the grid as of now, accounting for 23% of the energy mix. Merkel's bet is to replace nuclear power with renewable energies, a move that is expected to harm the German industry greatly by increasing its energy bill. In fact this will be the second most important factor to hit Germany's industrial competitiveness in a row, the first one being the actual exchange rate of the euro against its clients' currencies.

Even though Germany is the world's 4th biggest economy and Europe's number one, it is not bullet-proof. The last thing the German industrial sector needs is its energy bill rising non-stop or being unpredictable. Because let's face it, whether you are pro-nuclear or anti-nuclear you know shifting from nuclear power to any other source of energy is an expensive move. 
In the case of Germany, the shift will be made towards renewable energies, which are expected to add up to 35% of the total energy mix in 2022 (up from 13% today). In a country where the industrial sector takes more than 50% of the total energy used, the main problem with renewable energies will not be their price, but its unpredictability causing blackouts. The sun not shining, the wind not blowing or simply a specially cold winter day could cause a blackout on peak-hours. When renewable energies are used to cover domestic demand, this unpredictable behavior can be covered with some natural gas power plants, which are fast enough to be plugged into the grid when needed and disconnected shortly afterwards. But industrial demand is far bigger and more important, so that could mean said natural gas plants have to be on most of the day to avoid power disruptions, which would probably kill Merkel's objective of slashing carbon emissions by 40% in 2022, meaning she would have hurt German industry for nothing.
So what are the reasons for such a sudden rush in leaving nuclear energy behind?

Oil prices shape the present and the future of the economy

Modern economies are oil-junkies, and they will still be for a long time. Every movement in the price of oil, no matter how small, reaches the furthermost endpoint of the economy. Without hesitation I can say that oil price is the key factor shaping (and limiting) the behavior of our day-to-day economy. An even more important factor than interest rates or currency exchange rates, which are predominant in the long term.


Actual oil prices are the result of a deadly combination of circumstances: political instabilities in oil producer countries, a low exchange rate of the US dollar (still the preferred currency when trading oil), rise on total demand due to developing economies and last but not least speculation. The extended duration of this situation is very worrying for both oil consumers and oil producers. Consumers, meaning developed and developing economies as a whole, have their GDP growths strongly linked to oil prices, as it has the power to increase the cost of production and distribution processes and also personal transport expenses; all of them key drivers for a healthy economy.

On the other side, oil producers fear that high oil prices can harm demand. Even though oil demand has historically been highly inflexible, as energy is a primary need, it also has its breaking point. This breaking point is that where more expensive energy sources (think alternative energies) become affordable when compared with oil.
Oil producers are aware of this breaking point and on the last days we have seen reactions from Saudi Arabia and Kuwait, biggest and 7h biggest oil exporters worldwide respectively, saying they do not endorse such insanely high oil prices. They are profiting largely from these high prices, but at the same time they show some much needed common sense by acknowledging high oil prices can brake or break economic growth. They need their clients' economies to grow, to need more and more of their precious oil.
