Solar power: Affordable alternative energy – Fosters

Posted by Trish Riley, November 15, 2010

For the average person, most forms of alternative energy are out of reach.

Erecting a wind turbine is expensive and may not be worth it if there isn't enough wind — something the town of Kittery, Maine, found out when it pulled the plug on a $200,000 turbine at the transfer station because it didn't produce enough energy.

A geothermal system that extracts hot water from hundreds of feet below the surface is expensive, too — costing up to $40,000.

And underwater tidal turbine technology is generally too new for residential use and requires living near water.

Solar technology, however, is cheap, accessible, and reliable.
