Dedicated enviros shun consumption, and for good reason. But some consumer items aren’t all bad, and might even (gasp!) be good, particularly if they replace more harmful products or encourage greener living. We’ve rounded up 10 gadgets that a loyal greenie can covet in good conscience.

10 Bike Friday
This kick-ass bicycle doesn’t just fold up for easy storage and transport; it’s also a respectable touring bike. Use it for everything from multi-sport adventures (think bike-kayak-bike trips) to business travel. The only downside: Bike Fridays, like other foldables, are significantly pricier than your average commuter bike — but they’re also significantly cooler.

9 Freeplay EyeMax
Freeplay’s solar-powered radios come with an extra perk: when the sun is M.I.A., there’s a hand crank that lets you power your tunes with kinetic energy. One minute of cranking gets you about an hour of radio time. The cool blue Eyemax, priced at $49, also has a built-in LED flashlight. For each product ordered directly from Freeplay, $1 will be donated to the Freeplay Foundation, which promotes access to alternative energy solutions and education for poor communities in Africa.

8 LED Light Bulbs
Compact fluorescent light bulbs are so 2007. While CFLs are three to four times more energy-efficient than moldy old incandescents, LED light bulbs are more than twice as energy-efficient as CFLs — and they can last three times longer. Plus, unlike compact fluorescents, LEDs don’t contain toxic mercury. LED bulbs, which are made up of a number of single light-emitting diodes, come in a variety of sizes and shapes, from standard to festive, and perform a variety of functions, from lighting streets to greening chandeliers.

7 BoGo Light
Solar flashlights are a great alternative to the usual battery-drainers, particularly in areas where batteries are in short supply. Buy one BoGo Light from SunNight Solar for $25 and the company will donate another one to needy folks in the developing world.

6 Smart Strip
Household gadgets often suck up electricity even when turned off. To stop these “vampires,” you can plug your gizmos into a power strip that is easily turned off with the flip of a switch. The $40 Smart Strip takes this idea one step further with a feature geared toward computer and home-entertainment systems: when the device plugged into its “control” outlet is turned off (say, a TV), the Smart Strip cuts off the current flowing to peripheral devices (like a DVD player and VCR). That’s smart, all right.

5 Solio Charger
The Solio Classic taps the power of the sun to charge portable electronic devices like iPods and cell phones. Three small solar panels fan out to absorb as much sunlight as possible, then fold up when you’re done. One hour of sunshine will give you about 40 minutes of music or 15 minutes of talk time. The classic model sells for $100 in silver, black, white, or bright pink.

4 The Wattson
Who knew you could reduce your energy consumption by … buying an electronic device? The snazzy-looking Wattson wireless energy monitor collects detailed data about home energy use and then gives you a simple readout: a calming blue glow means you’re using energy sparingly, a fiery red indicates an electricity binge. By casting light on your energy consumption habits, this gadget could prod you to change your wasteful ways, significantly decreasing your energy bill. The Wattson sells for about $300 (£150).

3 Philips Eco TV
Sipping only 75 watts of power during normal use, and just 0.15 watts in standby mode, the Philips Eco TV uses less energy than a typical incandescent light bulb. In contrast, an old cathode-ray-tube TV consumes about 100 watts, while similar-sized plasma-screen TVs can guzzle anywhere from 200 to 500 watts. The Eco TV sports a 42-inch, flat-panel LCD screen, which — aside from making gadgetophiles drool — has the ability to automatically dim in response to ambient lighting and what’s showing on the screen. The TV, priced at about $1400, is also built from lead-free components and packaged with recycled materials.

2 Skystream Wind Turbine
Harvest the breeze in your own backyard with the Skystream 3.7. This residential-scale wind turbine hooks up directly to your home to augment or even replace the electricity you buy from your local utility. The Skystream ain’t cheap — $10,000 to $13,000 including installation — but on average it will save a homeowner $500 to $800 annually, so after a few years it’ll pay for itself. And in the meantime, you’ll be the coolest person at the block party.

1 Tesla Roadster
The Tesla Roadster is arguably the sexiest of all the green gadgets we lust after — and inarguably the most extravagant. This all-electric sports car goes 0 to 60 mph in under four seconds, has a top speed of 135 miles per hour, and travels 220 miles on a charge. All that for a base price of just $98,000.
