A new window into electron behavior

For the first time, physicists have developed a technique that can peer deep beneath the surface of a material to identify the energies and momenta of electrons there. The energy and momentum of these electrons, known as a material's “band structure,” are key properties that describe how electrons move through a material. Ultimately, the band structure determines a material's electrical and optical properties. The team, at MIT and Princeton University, has used the technique to probe a semiconducting sheet …

October 2017 was the second warmest October on record

October 2017 was the second warmest October in 137 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA's Goddard Institute for Space Studies (GISS) in New York. Last month was +0.90 degrees Celsius warmer than the mean October temperature from 1951-1980, just barely warmer than October 2016 (+0.89 °C). The warmest month of October according to the analysis happened in 2015 (+1.08 °C). The GISTEMP monthly temperature anomalies …

South Carolina Electric & Gas has a Plan to Replace Its Abandoned Nuclear Project

A $4.8 billion plan released Thursday from South Carolina Electric & Gas Company would put money back in the wallets of the state's ratepayers and use solar power and natural gas to make up for the cancellation of the V.C. Summer nuclear plant. Nuclear watchers have held up the South Carolina plant as an example of the last gasping breath of large scale nuclear in the U.S. While the overdue, costly …

Unlocking An Energy Revolution in Ethiopia With Lessons From the Black Market

“Ninety thousand solar lanterns sold last quarter,” said Mr. Li. He was sharing sales numbers for his solar appliance business in Ethiopia and I couldn't believe it. To put that number in perspective, the Global Off-grid Lighting Association pegs the average number of all solar lighting products sold in Ethiopia in a single quarter at around 250,000 units. Close to 80 perent of Ethiopians live in rural areas with little to no access to electricity. Assuming two lanterns for every household with an average five …

Stress can lead to risky decisions

Making decisions is not always easy, especially when choosing between two options that have both positive and negative elements, such as deciding between a job with a high salary but long hours, and a lower-paying job that allows for more leisure time. MIT neuroscientists have now discovered that making decisions in this type of situation, known as a cost-benefit conflict, is dramatically affected by chronic stress. In a study of mice, they found that stressed animals were far likelier to choose high-risk, …

Driving a Chanje electric electric cargo van: very big, far better than diesel

A Class 5 cargo van is a remarkably large vehicle, especially when navigating it through the mixed industrial and 19th-century residential streets of the Prospect Heights neighborhood in Brooklyn, New York. The Chanje V8070 electric cargo van, in fact, is the largest vehicle—electric or otherwise—we've ever driven. (We're still waiting...

The Gas Directive and Its Application to EU-Third Country Pipelines

The existing EU Gas Directive regulates issues pertaining to the transmission of gas from third countries to the Union, but is ambiguous. It can be interpreted in such a way that gas pipelines from these countries are not covered by EU energy regulations, leaving room for abuse. The European Commission's proposal to clarify the application of the Gas Directive […] The post The Gas Directive and Its Application to EU-Third Country Pipelines appeared first on The Energy Collective.

How to see the atmosphere

How can you see the atmosphere? The answer is blowing in the wind. Tiny particles, known as aerosols, are carried by winds around the globe. This visualization uses data from NASA satellites combined with our knowledge of physics and meteorology to track three aerosols: dust, smoke, and sea salt. Sea salt, shown here in blue, is picked up by winds passing over the ocean. As tropical storms and hurricanes form, the salt particles are concentrated into the spiraling shape we all recognize. With their movements, we can …

Batteries by Land, Sea or Air! (Cleantech Talk #35)

Though cars get most of the attention, batteries will participate in our cleantech energy transition on land, in the air and by sea. And in today's Cleantech Talk, we cover them all. It's something of a “double-cheeseburger” episode, in that we stretched ourselves around four topics instead of the usual two. Let us know in the comments if you liked the format, and if you have a few minutes, please leave us an iTunes review to make it easier for like-minded folks to find us!

California Law Will Streamline Permitting for Distributed Energy Storage

California is on the cusp of a dramatic jump in deploying cost-saving, climate-solving technology in the form of customer-sited energy storage, but the industry needs help cutting red tape that keeps the cost of the technology unnecessarily high for customers. Energy storage helps electricity customers and the electric grid in many ways: It reduces monthly bills; delivers grid services such as peak reduction, emergency backup and smoothing out the increasing share of renewable energy production; and it enables …
