Another step forward has been organic LEDs (OLEDs) which also promise greater efficiency and better light than older, incandescent bulbs.
They absorb the light and convert light to heat with incredible efficiency.
For example, updated fuel efficiency standards for light-duty and heavy-duty vehicles were incorporated in AEO2012 and AEO2013, tending to lower CO2 emissions relative to earlier projections.

What's more, the algorithms can be tweaked separately by hardware manufacturers for any desired result, and can incorporate data from ambient light sensors to increase projector efficiency.
It used a proprietary magnetic-pulse welding process, for example, to develop a lightweight, one-piece aluminum driveshaft that improves fuel efficiency for both light vehicle and commercial truck customers.

All engineering mumbo-jumbo aside, the resulting nanocone-tipped cells converted light-to-power with efficiency of 3.2% compared to 1.8% efficiency of conventional planar structure of the same materials.
FORBES: Nanocone-Tips Take Solar Cell Efficiency to Next Level
C. to announce the next round of a coordinated national program to improve fuel efficiency for cars and light-duty trucks for model years 2017 to 2025.
Sandwiching the solar cells inside the device would block some light out and knock down power conversion efficiency even further, Filler cautioned.
And over the next five years, we expect fuel efficiency standards in cars and light trucks to reach an average of 35.5 miles per gallon.
The system with a nitride semiconductor and a metal catalyst generates mainly formic acid from CO2 and water with light at a world's top efficiency of 0.2%.
In the previous approaches so far, the systems have had complex structures such as organic complexes or plural photo-electrodes, which makes it difficult to improve their efficiency in response to the light.
There's even a "white tag" market: When I install a more efficient light bulb, I can sell that efficiency gain to the fossil fuel power plant, just as if it's a green tag.
The practical applications could improve the efficiency of quantum computers, where light is often used to transfer information.

At the same time, efficiency programs are pushing more efficient light bulbs, air conditioners and other devices into homes.
An Eco Illumination2 light turns from red to green as driving efficiency increases and provides an awareness of driving habits.

The rising use of aluminum in passenger cars and light trucks comes because of rising fuel-efficiency standards in the U.S., he said.
The growth sector for the last quarter century has been light trucks, a category in which fuel efficiency has deteriorated over time.
He says that the FCC paper is only talking about the amount of light that's transmitted to the device, not the efficiency of the device itself.
Under the proposal, model year 2017-2025 cars and light-duty trucks are expected to achieve increases in fuel efficiency equivalent to 54.5 miles per gallon by 2025.

It puts new higher efficiency standards in place for everything from federal buildings down to light bulbs.
The important measure of success is the internal quantum efficiency, which shows just how good an LED is at making light.
There have been ideas about increasing energy-efficiency standards in buildings much as Carol has worked tirelessly to do with cars, light trucks and heavy duty trucks for the very first time.
Making small, light, efficient, cheap cars is hard, and harder as the standard for lightness, smallness, efficiency, and economy is raised.
