The moment Germany announced its highly publicized decision to phase out nuclear energy in the wake of the Japanese triple disaster; observers began to ask one very important question.
Just what energy source would replace such a huge swath of power in Europe's dominant economy?
The short-term solution had to be natural gas.
But this would make Germany more dependent upon imported energy, especially from Russia.
In that sense, the nuclear phase-out made the Nord Stream pipeline - from Russia, under the Baltic Sea, to northern Germany - absolutely essential.
Today, the first line of the twin pipeline is already in operation. The second should be on line at the end of next year (if not sooner).
Then there is the other Russian project - South Stream. This one intends to move Russian and Central Asian gas into Southern and Central Europe.
Much of that will also reach Germany.
In addition, several pipeline projects are vying for the excess production from the second phase of the Azerbaijani Shah Deniz offshore development in the Caspian Sea.
Included among these is Nabucco, a venture to bypass Russia and transport gas into the Baumgarten hub in Austria for ongoing distribution.
Nabucco has long been the European Union favorite, but it has been unable to attract sufficient supplies. Three other pipeline proposals also are attempting to secure the Caspian gas for transit to Europe.
But there is a problem for Germany in all of this.
It does not want to form an increasing dependence upon imported gas to power its economy.
And this sentiment is driving one of the biggest alternative energy revolutions in recent memory.
The German Push Toward Wind and Solar PowerThe 17 currently operating nuclear reactors in the country provide about 20% of the national electricity needs. Any replacement of those plants (where capital expenses are already sunk) will add significantly to the end costs of energy.
That means a political decision following the Fukushima Daiichi disaster one year ago ends up costing the average German citizen even more to secure what is already among the most expensive electricity in the world.
Germany does have shale gas.
But the furor over nuclear power is paralleled with a similar environmental concern regarding the dangers of fracking, a process of pumping water and chemicals under high-pressure to break open the rock and free the gas.
There are now four U.S. examples of seismic anomalies resulting from the combination of fracking and deep horizontal drilling.
And they have not instilled much confidence for the markets.
Instead, what the Germans are deciding to do is already being called the biggest restructuring of the national energy landscape since the end of World War II.
The government will initiate a campaign valued at more than $260 billion to harness wind and solar power.
The price tag is staggering. It is already pegged at more than 8% of the nation's entire gross domestic product (GDP). And it could move even higher.
This will involve huge wind farm areas in the Baltic and massive new high-power transit lines nationwide. The goal is to have at least 35% of the nation's power needs generated from renewable sources by 2020.
However, the developments of this massive policy shift are even more exciting.
