Does a full upgrade to solar power feel like too big a step? Terryville, Conn.-based NRG Dock has a neat idea: a relatively small, self-contained, solar power station that can power your electronics. The company is shipping a small line of independently operable solar-powered units designed for cell phones, portable computers and other devices. Better yet, 30 percent of the purchase price can be claimed as a tax credit, and that discount is even higher in some states. So this year, there may be no excuse for not going solar.
