While states are vying for clean energy funding and busy dedicating land to solar and wind farms, North Carolina's Progress Energy and Advanced Energy Corporation are scouting rooftops instead of land plots thinking about how to generate wind energy in the city, not in the country.

The two companies are searching for viable rooftops including parking areas to install windmills available to generate clean energy. The wind energy would then merged into the grid's clean energy portfolio.

Roofs cannot support the weight of massive windmills and there might be some visual, aesthetic, aviary, and air travel logistics that prevent large windmill blades from operating on every building in a city. Small-scale blades, such as those sold by Swift Wind Turbinewould be installed and will be spun by the updraft of wind currents. If this project works there is a plethora of opportunities across other metropolitan areas for those structures not already dedicated to solar panels or vegetated rooftops.

If the somewhat powerful wind currents can very efficiently generate clean energy to offset the amount equal to a building's lighting needs, for instance, then many buildings and cities can soar into clean energy and out of fossil fuel electricity. Hopefully these projects will work and make progress in transitioning from a system powered by foreign oil.Watch North Carolina for more information and wind power progress.
