Stop turning left!

Posted by Ben Fry on Wed, Jul 2, 2008 at 7:39 PM

If you want to reduce your carbon footprint and save some money in your ever-dwindling fuel budget you may want to stop making those time-consuming and wasteful left turns.

This strategy has been implemented by numerous companies, including UPS, FedEX and Home Depot. UPS’s routing software, also used by Home Depot, plans routes for drivers that minimize the number of left turns a driver makes. This measure reduces idling time if drivers have to wait to make the turn. While left turns cannot be completely eliminated, left-turn reductions have reportedly saved UPS over 28.5 million miles of travel, which in turn resulted in over three million gallons of fuel and shaved carbon emissions by 31,000 metric tons.

Many companies with freight-shipping operations are changing routes and shipping methods in order to reduce transportation costs. These are necessary strategies that make shipping operations more efficient and prevent excess costs from being passed onto consumers. For now, at least.

While I’m on the subject of reducing fuel usage (and all other carbon- and financially-related things that go along with it), there are plenty of good resources out there to help you find ways to cut back on fuel use. Check out this one, this one, and this one here.

Many of the recommended fuel-saving ideas are no-brainers and simply things we should be doing anyway, like checking tire pressure and skipping the air-conditioning when traveling at low speeds.

However, some are much harder to implement. I don’t personally like the idea of driving at the speed limit when on the interstate, but with the extra fuel costs associated with my 85-mile-per-hour habit, I may have to rehab my driving habits.

I will, however, continue to turn left when I need to. For now, anyway.

I enjoyed this post Abhishek. It was certainly creative and not what I was expecting when I clicked on Monster Energy hatsthe title – a title I might add, which is quite good. I know I had to find out what ways ‘guaranteed’ I could grow my list.

No one likes a Windows XP slow startup.When you startup your computer you want it to be ready to use immediately. I can not make it that fast, but I can help you fix Windows XP slow startup.First step to fix Windows XP slow startup is to find out what programs are loading when you startup Windows XP. To do this click start, run, then type in msconfig and hit enter. Look at the Boot.ini tab. In the box labeled Timeout change the time from the default 30 to 3. This changes how long it waits to before booting.
