Ever thought about putting solar panels on your roof? How about a wind turbine in your backyard? Besides the relatively high cost of the equipment, one of the big questions about renewable energy is whether or not it makes sense where you live. Some parts of the country have better wind or sun than others, and that can make a big difference when thinking about installing renewable energy. Fortunately there are some web based tools that can help you with this decision.
IMBY
The National Renewable Energy Lab (NREL) has a set of tools on their IMBY web page. The acronym stands for "In My Backyard", and they have tools for both solar and wind. The system uses a geographic information system (GIS) and allows you to see what sun and wind power is available where you live. You draw on the map where you want the panels (or turbine) and the program will tell you how much energy the system could generate. Combine this with the cost of your electricity and how much you use each month and it will help you figure out the financial payback of the system.
If you are interested in hydro power, the Idaho National Laboratory has a Virtual Hydropower Prospector - a system that can help you find potential hydro power applications. While probably not as useful to the average homeowner, still a pretty neat application. There could be similar programs for things like geothermal - if you have some spare time you can explore these websites along with the US Department of Energy site to find the information you are looking for.
Show Me The Money
Another useful tool is a website called DSIRE - Database of State Incentives for Renewables and Efficiency. By selecting the state you live in, you can see what government or utility incentive programs are available in your area. This is definitely worth your time if you are planning any improvement projects that involve energy efficiency or renewable energy. Quick example - if you live in Indiana and want to install a solar-powered roof vent, you may be eligible for a 50% tax credit (up to $1,000) - and that was just one of dozens of active programs in Indiana.
There are also some renewable energy companies that are offering their systems on a lease basis instead of purchase. Basically they install a system on your roof and you sign a contract that says you will pay a certain cost for the power generated over a set period of time (usually in the 10-20 year time frame so they can recoup their investment). While this may be a good deal, it is always wise to have the contract reviewed before you sign - while it might cost you a few hundred dollars to have a lawyer look it over, it could save you a lot of money down the road.
As always, the web is full of great information - but, be cautious and check your sources. Not everything you read on the web is accurate. If you are interested in renewable energy, take your time and do your homework. It will be worth it in the long run!
