Wind power. View of a large wind farm in California. Wind turbines are an important form of alternative power for electricity generation. They produce no emissions and have a low running cost. Modern turbines, which may vary the pitch of the blades, may adjust to varying wind speeds automatically, ensuring a more constant supply. The main drawbacks of wind power are a high initial capital cost and noise from the turbines. This area of California, San Gorgonio Pass, has about 3500 wind turbines, producing 600 million kilowatt-hours of electricity per year, enough to supply a town of 100,000 homes.

This vertical design rotor was erected by the Dornier company, better known for building aeroplanes, on a windy spot near Heroldstatt on the Swabian hills in 1990 as an experiment to measure how efficient it was at producing electricity from wind power. The big advantage of the design (which originates from 1931 from the French engineer Georges Jean Marie Darreius) was that the moving parts were at ground level and therefore easy to access for maintenance. Unfortunately, it became clear that this design was less efficient than the more familiar rotor blades attached to a horizontal turbine, and as far as I know this is now the only example of the Darrieus rotor still standing in Germany. It no longer runs. More information on the Darrieu...

Sunlight contains visible light and wavelengths of light that can be converted into electricity. Once only accessible to the well-off, solar power is making inroads to low-income households thanks to federal and state programs. Let's continue this trend and get solar power to the people!
