The REC maintains Pennsylvania's original Renewable Energy Online Business Directory with listings from more than 100 companies. Before beginning your search for an installer, see our starting a renewable energy project page for tips to save you time and money. Renewable energy systems are significant investments. We recommend you learn the basics of each technology before calling and review the questions listed below. Take your time to shop around, compare suppliers and find the one you feel comfortable with.
What is your energy usage and how much are you paying?What are your goals? (cost savings, environmental, helping to get the country off of foreign energy sources, etc.)Do you want a grid-tied system, grid-tied with battery-back up or an off-grid system?Where and how are you considering using the system or energy source?Do you plan on installing it yourself, helping to install it or paying an installer to do all the work?Do you plan on maintaining it or paying someone else to maintain it?
Typically renewable energy systems installers conduct a site visit which can cost $50 - $300 or more so first you should askWhat is included in a site assessment and what do you charge?Do you perform an energy use assessment?How does the system work and how will it supply my building, home, vehicle with energy? Make sure you understand this very clearly and ask them to repeat anything you don’t understand.How much energy might the system generate/produce?Is there a performance guarantee?What is a typical system cost?What financial incentives exist to help pay for it?Have you worked with any lenders that have experience with renewable energy systems?What can I expect in terms of payback (when you’ll make your money back)?What do I need to know in terms of building and electrical permitting? Zoning? Who is responsible for obtaining the proper permits and approvals?How long will the system last? How do you know that for sure?Do you provide a maintenance or service warranty for the first year? Can I purchase an extended warranty? What can I expect if maintenance is needed? Is regular maintenance needed? How often and what type?How long have you been in business? What certifications do you have? How many installations have you done? Do you have references I can contact? Pictures of previous installations? Installations I can visit?When could the installation take place? From start to finish, including permitting and utility approvals, how long might the installation take? What can I expect from the installation itself in terms of disruptions to the building/site? Describe the installation process.Do you work with my electrical utility to complete the grid interconnection?Are there interconnection costs I should be aware of?Have you worked with my utility before? What utilities have you worked with?
Biodiesel is a clean-burning fuel produced from vegetable oils and animal fats through a chemical reaction and meeting ASTM D 6751 standards, which ensure that all biodiesel behaves in the same way.Biodiesel contains no petroleum, but it can be blended at any level with oil or diesel. Biodiesel is different than ethanol and is also different from running an engine or boiler on vegetable oil.Common biodiesel myths: 1. "Biodiesel is cheaper than conventional diesel and/or gasoline"--unless you make your own, in most cases it isn't any cheaper but it does help us diversify our fuel system and reduce our dependence on fossil fuels2. "100% biodiesel can be used year-round"--in most cases this is not true and if the temperature drops below 32 degrees biodiesel can gel and create problems. Blends of no more than 20% are recommended during days when the temperature is below 32 degrees.USES OF BIODIESELIt can be used in home heating oil systems safely with no modifications to the fuel tanks, pumps or burners in concentrations up to 5% biodiesel. For fuel blends between 6% and 20%, minor changes (including a pump with proper seals) may be required. Up to 100% biodiesel can be used in any diesel-burning vehicle with no modifications. In fact, the high lubricity of biodiesel lubricates your diesel engine and prolongs its life.You can buy the biodiesel from one of the providers listed in this directory, or you can make your own out of fresh or used vegetable oil.Warning: making your own biodiesel involves the use of dangerous chemicals and we highly recommend that you research the dangers and protect yourself--as well as dispose of the chemicals in a responsible way by contacting your solid waste authority.

How do you know if a PV installer is capable?
A wind generator’s rotating blades convert the wind’s kinetic energy into the rotational movement of a shaft. The rotating shaft turns an alternator, much like the one in your car, which makes electricity. This electricity is transmitted through wiring down the tower to its end use.The most common wind turbines are horizontal axis tubines and feature three blades. Vertical axis turbines (often shaped like a double-helix) hold a lot of promise and are coming to the market but generally their performance has yet to be proven and they are typically more expensive.Generally speaking, you need at least a 1/2 acre of open land where you can mount the turbine on a tower (though this depends on local zoning and regulations), and your annual average wind speed should be at least 10 - 12 miles per hour. We have several resources for you to more fully understand your wind resource: the County Wind Maps for Pennsylvania and our Community Wind Project which provides wind assessment services for mid-sized projects. You can also ask the small wind professional you contact for more information on the wind resource at your site.In Pennsylvania, wind resource is strongly related to elevation, so the higher you are in elevation the better the wind resource. Generally properties with 1,500 - 2,000+ of elevation are best suited for wind energy. You can put a wind turbine just about anywhere and it will generate electricity. . .the question is how much and if the result satisfies your financial goals and other desired results.When considering wind power, keep in mind that the tower needs to extend the turbine at least 30 feet above nearby obstructions such as trees, buildings or hills. These create turbulence in the air causing the wind turbine to work very inefficiently. The general rule is "the higher the better" and we recommend using at least a 60+ foot tower and 100 - 110 feet is even better.Typical installed costs can range from $15,000 - $20,000 for a 1.8 kilowatt turbine (approximately enough electricity for 1/2 - 1 average U.S. home) to $50,000 - $60,000 for a 10 kilowatt turbine (enough for 3 - 4 average U.S. homes).See what different kinds of turbines are out there with this list of small wind turbine manufacturers.
