The expansion of renewable energy has been widely criticised for increasing weather-dependent fluctuations in European electricity generation. A new study shows that this is due less to the variability of weather than from a failure to consider the large-scale weather conditions across the whole continent: many European countries are unilaterally following national strategies to expand wind energy capacities without looking beyond their own backyard.

It would be better, however, for individual countries to work together and to promote the expansion of wind capacity in other European regions that are currently making very little use of wind power.  Balancing capacity across the continent would effectively minimise the extreme fluctuations caused by the varied weather conditions that currently affect wind speeds. This is the conclusion reached by a group of weather and energy researchers from ETH Zürich and Imperial College London in a new study, which has just been published in the journal Nature Climate Change.

A concentrating photovoltaic system with embedded microtracking can produce over 50 percent more energy per day than standard silicon solar cells in a head-to-head competition, according to a team of engineers who field tested a prototype unit over two sunny days last fall.

"Solar cells used to be expensive, but now they're getting really cheap," said Chris Giebink, Charles K. Etner Assistant Professor of Electrical Engineering, Penn State. "As a result, the solar cell is no longer the dominant cost of the energy it produces. The majority of the cost increasingly lies in everything else — the inverter, installation labor, permitting fees, etc. — all the stuff we used to neglect."

It’s been a few years of soul-searching for Tim Duncan, the CEO of Talos Energy. The Houston-based oil company has long specialized in the shallow waters of the Gulf of Mexico off Louisiana and Texas. Yet the oil bust that began in 2014 has made the region deeply unpopular. Facing dwindling prospects for big new finds offshore, companies have instead flocked to the Permian basin of west Texas, where layer upon layer of oil-saturated rock promises decent returns even at stubbornly low oil prices.

“We resisted the temptation to join the land race onshore,” says Duncan. But Talos did go somewhere new: Mexico. 

A SEAS researcher helped develop technology that could become the most efficient solar cell in the world.

Most of today’s lithium-ion batteries, which power everything from cars to phones, use a liquid as the electrolyte between two electrodes. Using a solid electrolyte instead could offer major advantages for both safety and energy storage capacity, but attempts to do this have faced unexpected challenges.

New research from a professor of engineering at UBC’s Okanagan Campus might hold the key to biofuels that are cheaper, safer and much faster to produce.

“Methane is a biofuel commonly used in electricity generation and is produced by fermenting organic material,” says Cigdem Eskicioglu, an associate professor with UBC Okanagan’s School of Engineering. “The process can traditionally take anywhere from weeks to months to complete, but with my collaborators from Europe and Australia we’ve discovered a new biomass pretreatment technique that can cut production time nearly in half.”

Since 1988, a mere 100 companies have been responsible for 71 percent of the entire world's industrial greenhouse gas emissions.

This data comes from an inaugural report published by the Carbon Disclosure Project (CDP), an environmental non-profit. Charting the rapid expansion of the fossil fuel industry in the last 28 years, they have now released some truly staggering numbers on the world's major carbon polluters.

Brandon Jackson, a doctoral candidate in mechanical engineering at Michigan Technological University, has created a new computational model of an electrospray thruster using ionic liquid ferrofluid—a promising technology for propelling small satellites through space. Specifically, Jackson looks at simulating the electrospray startup dynamics; in other words, what gives the ferrofluid its characteristic spikes.

The future cost of energy storage technologies can now be predicted under different scenarios, thanks to a new tool created by Imperial researchers.

Using a large database, the team can predict how much consumers will have to pay in the future for energy storage technologies based on cumulative installed capacity, current cost and future investment.

Can you imagine fully charging your cell phone in just a few seconds? Researchers in Drexel University’s College of Engineering can, and they took a big step toward making it a reality with their recent work unveiling of a new battery electrode design in the journal Nature Energy.

The team, led by Yury Gogotsi, PhD,Distinguished University and Bach professor in Drexel’s College of Engineering, in the Department of Materials Science and Engineering, created the new electrode designs from a highly conductive, two-dimensional material called MXene. Their design could make energy storage devices like batteries, viewed as the plodding tanker truck of energy storage technology, just as fast as the speedy supercapacitors that are used to provide energy in a pinch — often as a battery back-up or to provide quick bursts of energy for things like camera flashes.
