The memory standards committee known as the JEDEC Solid State Technology Association announced the publication of JEDEC DDR3L, which the association says will enable a significant reduction in power consumption for a boatload of products that utilize memory, including laptops, desktops, servers, networking systems, and a a range of digital devices.
Those of you donning your detective caps might have guessed that the "L" in DDR3L stands for "Low Voltage," and you'd be right. Devices that adhere to the new standard will operate from a single 1.35V power supply voltage compared to 1.5V in existing devices, JEDEC said.
DDR3L-based memory devices will consume 15 percent less power compared to standard DDR3 (sometimes more), and a whopping 40 percent less than standard DDR2, all without taking a performance hit. The upshot here is longer battery life and cooling running devices.

I'm no tree hugger but why is it everyone has tunnel vision with improvments like this? So its only a couple volts who cares thats not gona appear on your electricle bill. Maybe not. BUT take those couple volts and multiply it by the million/billions of people who have or will be getting ddr3. couple volts just turned into a whole lot.

the difference in power consumption and heat production on memory at 1.35v vs. 1.5v is negligible when compared to other components of laptops and even less in desktops. This may sound all warm and fuzzy but it really doesn't do squat when compared to changing a CPU or a dedicated GPU. Unless you're using a netbook, you're not going to notice a difference.

I'm all for "cooler" running devices considering how the PC keeps my small office warm all winter.
