Green Your Father's Day: Take Him Solar

Father’s Day is this Sunday, so this week's tips are about the greenest ways to thank dads.

Tip #4: Plug him into renewable energy.

If your dad loves gadgets, consider getting him a solar-powered charger for his laptop, phone, iPod, or other favorite electronic. Solio and Goal Zero have popular lines in an array of price ranges. Dad'll be saving energy, and you'll be likelier to convince him to go camping with you: Solar power doesn’t need a plug, so he won’t miss any important calls out in the woods.
