WITNESS: Money falls from the sky in Germany

BERLIN (Reuters) - My father warned me "money doesn't grow on trees" and he was right, of course.

But I have discovered that money can fall out of the sky -- if you have the equipment to catch it.

In an age of global warming, rising fossil fuel prices and dwindling natural resources, I've learned that in Germany and a growing number of countries, solar power can give you more than just a feeling of "doing something" for the environment.

It can also give you a steady stream of income.

My roof has been turned into a cash machine, thanks to a state-mandated "feed-in tariff" that requires utilities to pay anyone who installs a photovoltaic system more than double the market rates for the electricity produced for the grid.

The 34 sleek black panels, measuring about 1 meter by 1.5 meters (yards) each, lie inconspicuously on the slopes of the roof as they quietly harvest enough power for two households -- and generate annual revenues of some 3,600 euros ($5,300).

In other words: Every day about 10 euros ($15) worth of energy from the sun (or even daylight) lands on the roof and is converted into electricity through the wonders of photovoltaic.
