Earth Day is Sunday, April 22. And no, that doesn’t mean you have to go out and hug a tree. But you might be interested in a few nifty high-tech green gadgets that can save energy, make your life generally easier and ease any of that green guilt you may be harboring. Plus, they’re cool to show off.

Here’s a sampling of eco-cool gadgets shown at the recent EcoFocus event in New York City, from solar and kinetic energy chargers to an auto-sensing light switch to a powerful phone whose case is made up of recycled plastics. We’ve also got an award-winning LED bulb and mobile apps for a thermostat.

Oh, did we throw in an extra green gadget? So we did. Happy Earth Day.
