Solar Power for Your Laptop, iPod & More

It’s been quite some time since I lived in a dorm room, I admit — over 40 years in fact (yikes!) — and at the time, using renewable energy in my room was not really on my cultural radar.

But today is far different. Renewable energy and reducing carbon emissions are talked about all the time; and while you may not be able to install solar panels or sign up for green power at college, you can still make a difference.

You pretty much have two (and a half) options though: Portable solar power chargers for your laptop and electronic gadgets , Rollable Solar Panels and buying carbon offsets.

Solar Power For Your Gadgets
Even though there are some portable wind power generators out there, skip them and concentrate on portable solar power chargers for your electronics.

SolarWindSuperMall has covered a number of these before a number of times and is a good place to start to get a handle on what’s out there: First the portable solar power  backpacks , the  original Reactor Solar Backpack, the new stylish  foldable solar power charger from Coleman  or the AA NiMH or NiCD battery solar charger – compact foldable unit. All are worth investigating.

Buy Carbon Offsets For Your Electricity Use
You’re probably familiar with carbon offsets for your flights, but most of the same people from whom you’d purchase these also sell offsets for your personal electricity use — Sometimes these are for renewable energy projects, other times they are for other carbon sequestering projects. In any case, they’re a good way to reduce the impact of your electricity use.

CarbonFund.org is one service which I reference a lot. They have offsets for your home either by preset amounts or by entering in your exact electric usage.

You’ll have to tweak their system though: Since you’re in a dorm room and never see an electric bill you’re stuck with presets, and the smallest one of those is for an apartment (under 1000 sq ft). You’re dorm room is undoubtedly much smaller than that, so the $50 is probably overkill. Based on their numbers, something like $25 is more like it, so adjust the numbers accordingly for a more appropriate offset.

There are other services out there to choose from, keep in mind, and a quick search will turn them up. Just make sure they’re reputable.

There is no more irritating dead weight than a bag of batteries in your backpack.  You brought them along because you wanted extras for your your camera, maybe a cell phone or your GPS, and that little pocket radio with the emergency weather band that really doesn’t take up any space and weighs just an ounce, and that small flashlight you might need.  Now that you’ve weaned yourself away from modern civilization none of that seems really necessary.  It’s just heavy. Carrying extra batteries is simply out of the question.   And since you want to be  ecologically responsible now, you won’t bury the little toxic packets beside the trail after they have reached the end of their usefulness either.  If you packed them in,  then you have to pack them out.
The best solution to wilderness power needs–the solar panel–that was once too fragile and too expensive only a few years ago, is the Foldable Solar Charger.  Now rollup panels that lash to your pack or stow in a pocket are within the reach of any cost conscious environmentalist willing to crunch numbers and look at the long term. If you shop for new gear, one of your choices will be a backpack with solar charger built in. It’s a tough idea to pass up.
