Cars that operate on solar power can cut down on carbon emissions a lot, but this system is not perfect yet. Having said that, small power machines that run on solar energy are available. Solar powered generators can be purchased, and are a great source of energy in emergencies.
Talk to your local government about doing any major solar installations in your home or business. You want to be properly permitted and within building, zoning and construction codes and regulations. However, you may also discover tax credits, rebates and other financial incentives. They may also have data and information about how well certain solar technologies work in your area.
