As this article describes, the German power grid averages 21 minutes per year because it has buried its power lines. Yes, Germany is much more dense than the United states, and yes, it would be very expensive to bury power lines in all of the country's major metropolitan areas. However, such an investment would be hugely beneficial for decades.

When the government stimulus was passed during the financial crisis, money was supposedly allocated for infrastructure projects. Some money should have been allocated to begin burying America's power lines. The project could have be undertaken over 25 years, and could be targetted to the most dense areas that do not already have underground lines. Burying all of the country's power lines is probably unrealistic, but a project like I described would be a good start.
