A Year-End Update on Electricity Policy From the Field

The electricity sector’s competitive dynamic completely flipped in 2017. It is now cheaper to build new wind and solar than new coal or often natural gas. In growing swaths of the country, it’s often cheaper to build new wind (and sometimes solar) than continuing to run existing coal plants. Show More Summary

Image: SDO spies broad coronal hole

A broad hole in the corona was the sun's dominant feature November 7-9, 2017, as shown in this image from NASA's Solar Dynamics Observatory. The hole is easily recognizable as the dark expanse across the top of the sun and extending down in each side.

Solar X-Ray Bursts Impacting Earth --"Haven’t Been Detected in the Past”

“This is an exciting result, showing Earth’s atmosphere is more closely linked to solar X-ray variability than previously thought,” Hayes said. “Now we plan to further explore this dynamic relationship between the Sun and Earth’s atmosphere.” Stretching from roughly 30...        

NASA's Solar Dynamics Observatory Spies a Strange 'Circle' on the Sun

NASA's Solar Dynamics Observatory came across a rare phenomenon this week when their spacecraft observed a dark filament encircling an active region (Oct. 29-31, 2017). Solar filaments are clouds of charged particles that float above the sun, tethered to it...        

Image: Solar Dynamics Observatory spies rare encircling filament

NASA's Solar Dynamics Observatory came across an oddity that the spacecraft has rarely observed before: a dark filament encircling an active region (Oct. 29-31, 2017). Solar filaments are clouds of charged particles that float above the sun, tethered to it by magnetic forces.

NASA investigates invisible magnetic bubbles in outer solar system

Space may seem empty, but it's actually a dynamic place populated with near-invisible matter, and dominated by forces, in particular those created by magnetic fields. Magnetospheres—the magnetic fields around most planets—exist throughout our solar system. Show More Summary

Working Together, Small Solar Firms Compete With Big-Name Rivals — Episode 45 Of Local Energy Rules Podcast

Fast-improving technology and growing consumer interest continue to put momentum behind the clean energy transition. Unlike utilities and other industry players that have largely ignored growth opportunities as market dynamics shift, a coalition of independent solar companies is harnessing its combined power to command more influence in the marketplace.

Image: NASA's SDO spots a lunar transit

On Oct. 19, 2017, the Moon photobombed NASA's Solar Dynamics Observatory, or SDO, when it crossed the spacecraft's view of the Sun, treating us to these shadowy images. The lunar transit lasted about 45 minutes, between 3:41 and 4:25 p.m. Show More Summary

How solar peaker plants could replace gas peakers

(SolarPACES) Under a technology 2 market R&D contract with the DOE, CEO Hank Price of Solar Dynamics did the math on operating a tower CSP project in Arizona or California as a solar version of a typical gas peaker plant, by storing all of its solar energy thermally to be delivered in the evening just for 5 or 6-hours as dispatchable CSP (D-CSP).

Utilities: Solar Trade Protections Do More Harm Than Good

Over the past several years, utilities and public power producers have increasingly diversified their portfolios for a variety of strategic reasons in a dynamic that echoes the U.S. government’s own “All of the Above” energy strategy. Show More Summary

Why Has Our Sun Been Freaking Out So Much Lately?

The solar flare as seen by NASA's Solar Dynamics Observatory on September 10, 2017. (Image. NASA/SDO/Goddard) Since early last week, the Sun has belched out a steady stream of solar flares, including the most powerful burst recorded in the star's current 11-year cycle. Show More Summary
