I picked up a couple of the new Philips 10.5-watt 800-lumen LED bulbs this weekend. All around, they’re the best sub-$20 LED bulb I’ve seen yet.
I learned something incredibly useful this week: For every 3 watts of energy consumption you save, you save an additional watt of power in cooling costs during the cooling season.
I bought my first CFL bulb a little over 9 years ago. I knew this was helping my AC costs too, but now I know how much.
I was at Micro Center today, picking up CD jewel cases and USB flash memory and a cheap USB game pad. And to buy a little extra time–I had one son with me and the other was home napping–I wandered around. In the memory aisle, I spotted some Samsung “green” memory. Manufactured with a 40nm process instead of the usual 60nm process, the modules are 2/3 the size of conventional modules, run cooler, and use up to 47% less power.
Is it worth paying extra for? As always, it depends.
I occasionally read an offhand comment where someone says he or she just bought a new computer, and the new computer is so much more power efficient than the old one, it’s going to pay for itself.
I wonder if they did the math, or if that’s what the salesperson told them. Because while I can see circumstances where that assertion would be true, but it typically would involve extremes, like replacing an aged Pentium 4 computer with, well, a netbook. They probably didn’t do that.
Part of the reason I got into computers professionally was because I was tired of hearing lies from salespeople and technicians. So let’s just take a look at this claim.
