More and more research is being put into Solar-wind hybrid turbines, since predicting either wind or sun can be difficult. Many different designs are being tested to determine if there is an efficient way to combine the two. Installing solar panels on the already existing wind turbines was tested, but produced blinding rays of light that posed a threat to airplanes.
These beams also had the potential to cause fires if concentrated. The solution to this was produce tinted solar panels that do not reflect as much light. Another proposed design was to have a vertical axis wind turbine coated in solar cells that are able to absorb sunlight from any angle. While these designs are still being tested, scientists are having success, and these new hybrid units are a very promising project.
