Generating electricity from solar panels installed on roof tops is not a new idea. More people who live in condominiums and co-op apartments are now considering this solar option. They are tired of rising electricity costs and want to embrace renewable energy.

Condominium and Co-op Apartment associations and owners of larger commercial buildings can reduce their electricity costs and go green by installing wind energy on their roofs. The technology is here. All it takes is some persisitence.

Heating and cooling our houses is getting more expensive and accounts for 17 percent of greenhouse gas emissions. It's time to put the the sun and the 78 million house roofs to work with solar photovoltaic roof modules. By doing so, you could reduce your electricity needs by 30-50 percent.

When we hear metal roofs, we usually think of warehouses and commercial buildings. Not any more. Home remodelers are now using them for porches, porticos and entire roofs. They're also literally cooler than asphalt roofs.

Overhangs and porches provide shelter and beauty to a house. They also cut down on natural light entering the main part of a house. Skylights installed in overhangs and porches solve this problem.
