“Witchgrass” Switchgrass: A Feedstock for Future Flights

You might think it would take a Halloween trick to transform grasses, corn husks, and other plants and organic waste into fuel you can use to power your car or an airplane. But scientists are already figuring out how to use chemical processes at a biorefinery to cost-effectively convert the sugars from non-food plants and wastes into biofuel. Biofuels are already powering some airplanes—and that’s no trick!

How Much Power is 1 Gigawatt?

Today marks the one-year anniversary of “Back to the Future” Day.

It’s a date most movie buffs know by heart: October 21, 2015 – the day Marty McFly and Doc Brown travel to the future in Stephen Spielberg’s 1989 classic “Back to the Future: Part II.”

Although you may not have remembered the date, you’ve probably heard of Doc’s DeLorean, which takes 1.21 gigawatts (GW) of power to travel through time. Admittedly, our national labs haven’t quite figured out time travel just yet, but they do analyze power.

Renewing Forests in Colorado: Opportunities for Bioenergy

Decomposition of dead trees occurs naturally and is healthy for a forest ecosystem. However, too many dead trees makes the region prone to forest fires that are costly and dangerous to contain. Recent advances in biofuel technologies are bringing us closer to turning those dead trees into biofuels.

Making Our Solar Future with American Manufacturing

Every second that ticks by, six solar cells come off U.S. manufacturing lines that contain crystalline silicon. In 10 years, the Energy Department’s SunShot Initiative expects nearly three-times that amount to be racing across the lines, helping to make America a leader in high-tech solar manufacturing.

With SunShot funding, 1366 Technologies developed these three-dimensional silicon wafers that require fewer raw materials, helping to reduce the cost of solar panels.
EERE Success Story – Silicon Solar Wafers Enter a New Dimension

The vast majority of solar modules are currently made with silicon, as the material is widely available, relatively low-cost, and able to reach high efficiencies. Today, nearly all silicon wafers for solar modules are manufactured by first transforming the raw material into silicon blocks, which are then sawed into thin wafers that are turned into solar cells and integrated into modules. But one SunShot Initiative awardee has developed a method that is changing the game.
