Going it alone nationally or Europe-wide could act as trigger for worldwide action.
Germany, for example, is well on its way to use the Renewable Energies Act (Erneuerbare-Energien-Gesetz) for developing new mature technologies.
Now improvements in the German Renewable Energy Law are necessary to accelerate this development.
At this point, power from Renewable Energies is still slightly more expensive to produce, though the higher cost is offset by the creation of new future-oriented jobs and by getting more independance from imports of coal, oil and natural gas.
The anxious oogling of other countries to see whether they offer a similar contribution to climate protection, makes rather little sense from the point of view of industrial policy; it is almost laughable: When did a country ever base the development of new products on whether the other countries contribute "appropriately"? Did Henry Ford wait for Germany to start mass production of the automobile? Should a German wind farm builder restrain himself just because other countries do not share in the windmill production?
Thanks to the Renewable Energies, Germany already produces 16 percent of its electric power without the emission of CO2, and the number of installations is steadily rising. Mass production continuously lowers cost. In only a few years, power from this type of facility may be cheaper than power from a coal, oil, or gas-fired power station. At that moment, people all over the world will prefer to purchase solar facilities, wind farms, biogas mini power stations, and power storage facilities rather than Diesel generators or coal-powered stations.
And what can you personally do?
Bring up the subject of "100 percent" at any opportunity!
The demand for 100 percent Renewable Energies must never fall silent.
