|Photovoltaic (solar) cells:
Solar photovoltaic cells (PV) convert sunlight into electricity. They are a series of connected silicon wafer cells attached typically to a metal support. There are various types: amorphous, monocrystalline, and polycrystalline silicon; thin-film, and otherseach has advantages and deficits in terms of cost and efficiency. The PV cells generate DC (direct current) electricity, which is usually converted to AC, (alternating current used in most homes in this country) by an inverter. The system may be a stand alone/off-grid system combined with rechargeable batteries (some systems also add a gas/diesel generator to recharge the batteries when there has been a series of cloudy days); or grid-tied, which eliminates the need for batteries by drawing electricity from the grid when the cells aren't producing current. PV modules can continue producing electricity for decades, and need minimal maintenance. Though initially expensive, there are significant government incentives to help you pay for your PV system. If you have a grid-tied system and generate more electricity than you use, our local utility is required to purchase your extra electricity (see: Tax Incentives & Rebates). An important consideration when planning a PV system, is to use appliances (EnergyStar) and lights (CFL's, LED's etc.) that use less electricity; this allows you to build a smaller, and therefore less expensive system. Small scale wind turbines, and even micro-hydro systems can also be used to generate electricity.
Note: CFL's contain a minute amount of mercury, and should be disposed of properly; Methow Recycling is planning to set up a recycling program for CFL's. IKEA and Home Depot accept CFL's for recycling. see www.lamprecycle.org

And while there isn't a magic alternative energy bullet (yet), if you're remodeling or building a house, choosing to install an alternative energy system (PV, Wind, microhydro) is a wise consideration. The payback period is getting less all the time, and the ROI (return on investment) is getting nicer. Top consideration: If you do it now, you will be taking a significant step to bring your house out of the environmentally destructive path we all travel.
