Finding a Common Ground Between Energy Efficiency and Solar Photovoltaic Systems

Everyday at the Co-op we receive requests for information from members wanting to add solar photovoltaic panels to their houses. Our members are concerned about the environment as well as their electrical usage and they want to make the right choice in benefiting themselves and reducing greenhouse gases. The first thing we do is make them aware of our long-term contract (till 2011) with our power supplier the Bonneville Power Administration (BPA) where we purchase 100% renewable hydro-generated electricity.

Second, we ask them what their monthly electrical usage in kilowatt hours (kWh) is. This allows us to see how much electricity they themselves use; it also gives me an idea of how efficient their house and appliances are. Unless your house, appliances, and lighting are as efficient as possible, it makes no sense to install a photovoltaic system because it will be larger and more expensive to generate enough power to handle your needs. In states that offer incentives for solar photovoltaic installations, energy efficiency is at the top of the list in considering a project for funding. The kilowatt hours that are saved by efficiency are the first step in reducing your house’s electric load. They might not be as glamorous or trendy as an alternative renewable energy system but they are your best investment in terms of getting the most for your money!
