The main cost of an electric vehicle (EV) is its battery. The high cost of energy-dense batteries has meant EVs have long been more expensive than their fossil fuel equivalents.

But this could change faster than we thought. The world’s largest maker of batteries for electric cars, China’s CATL, claims it will slash the cost of its batteries by up to 50% this year, as a price war kicks off with the second largest maker in China, BYD subsidiary FinDreams.

What’s behind this? After the electric vehicle industry experienced a huge surge in 2022, it has hit headwinds. It ramped up faster than demand, triggering efforts to cut costs.

The report features six studies that thoroughly examined MIT’s superconducting magnets design used in its breakthrough fusion test.

Scientific and technical research in the United States has led to decades of progress in energy efficiency, as we have seen on previous occasions. However, we have just learned of a breakthrough that was only theorized until now, finally, it has been put into operation. This is the first-ever reverse microwave, which cools food instead of heating it. Could you simply imagine that?

A reverse microwave is an innovative appliance that rapidly cools food and drinks without using electricity. Unlike a traditional microwave oven which uses microwave radiation to heat items, a reverse microwave utilizes thermoelectric cooling.

This technology allows the reverse microwave to draw heat away from the contents inside, lowering their temperature in just minutes. The concept behind reverse microwaves has existed for decades, but the technology is only now becoming available for home use in the United States.

Daimler’s new, all-electric truck brand made its Canadian debut this week with the official market launch of its battery electric class 4 and 5 medium duty work trucks.

After making its North American debut at the 2023 ACT Expo in Anaheim, California, Daimler Truck’s RIZON brand has continued on a steady march towards production with initial preorders set to open this June. But it won’t just be Americans who can order a new RIZON electric box truck – Canadians will be able to add them to their fleets at the same time.

“Canada is very advanced regarding green energy and infrastructure and is a natural next step for RIZON’s second market,” explains Andreas Deuschle, the Global Head of RIZON. “We are very happy to bring our zero-emission solution to Canadian customers. They are proven OEM trucks with the latest technology from Daimler Truck.”

As summer approaches, electricity demand surges in the U.S., as homes and businesses crank up the air conditioning. To meet the rising need, many East Coast cities are banking on offshore wind projects the country is building in the Atlantic Ocean.

For electric grid operators, knowing how much wind power these offshore turbines can harvest is critical, but making accurate predictions can be difficult. A team of CU Boulder scientists and their collaborators are working to tackle the challenge.

In a paper published March 14 in Wind Energy Science, a team led by Dave Rosencrans, a doctoral student, and Julie K. Lundquist, a professor in the Department of Atmospheric and Ocean Sciences, estimates that offshore wind turbines in the Atlantic Ocean region, where the U.S. plans to build large wind farms, could take away wind from other turbines nearby, potentially reducing the farms’ power output by more than 30%.

Dielectric capacitors are ubiquitous components that play a vital role in electronic devices and energy storage systems. Their ability to rapidly discharge significant amounts of energy makes them indispensable for high-power applications.

“High-energy and high-power capacitors are the backbone of reliable power supplies, especially as we transition towards renewable energy sources,” explains Alamgir Karim, Dow Chair and Welch Foundation Professor of Chemical Engineering at UH and a faculty mentor on the project. “However, current dielectric capacitors fall short in terms of energy storage capacity compared to other options like batteries. The advantage of capacitors lies in their superior power density, making them a more suitable choice for various applications.”

The key factor influencing a capacitor’s energy storage is a combination of its permittivity (ε) and dielectric breakdown strength (EBD). Professor Karim emphasizes, “To enhance a capacitor’s energy storage, advancements in both these aspects are crucial.”

The world’s first artificial energy island is being built off the coast of Belgium and will serve as future interconnector between countries as well.

Imagine you’re in a car, pedal to the metal, racing down the highway, but no matter how hard you push, you can’t surpass the speed of the car next to you, which is effortlessly cruising at the same pace. Now, replace the car with light, and you have a real cosmic conundrum: why can’t anything go faster than light?

Back in 1905, Albert Einstein turned the world of physics upside down with his theory of relativity. This wasn’t just about E=mc² or the bending of space-time; it was about something that touches everything we do: the speed of light, which is roughly 299,792 kilometers per second. According to relativity, no matter how fast you’re moving towards or away from a light source, you will always measure the speed of light at the same constant velocity.

Long confined to regions with volcanic activity, geothermal promises to become a much more versatile energy source thanks to new technologies.

Glistening in the dry expanses of the Nevada desert is an unusual kind of power plant that harnesses energy not from the sun or wind, but from the Earth itself.
