We – a team from Rwanda and Germany who work in the field of renewable energy scientific modelling – set out to find the answer by building the Renewable Power Plant Database Africa, the first on the continent. It’s a database of available open access data on hydro, wind and solar energy sources that we’ve analysed.

The database shows that some countries, such as Nigeria and Zimbabwe, have enough projects in the pipeline to potentially transition away from fossil fuels by 2050. And that 76% of all electricity required on the continent could come from renewable resources by 2040. This would happen if the capacity of existing hydro-, solar and wind power plants were fully utilised and if all plants currently on the drawing-board were built.

The 76% from renewables would be met by 82% hydropower, 11% solar power and 7% wind power. Hydropower has been the main renewable energy resource to date, but declining costs for solar photovoltaics (90% decline since 2009) and wind turbines (55%–60% decline since 2010) mean solar and wind have potential to lead sustainable renewable energy options.

The Sun emitted a strong solar flare, peaking at 4:56 p.m. ET on March 28, 2024. NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.” NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.

Kia’s first three-row electric SUV is off to a good start. However, Kia will accelerate EV9 momentum with plans to begin US production by May. Kia expects the EV9 will qualify for the full $7,500 EV tax credit by early next year.

After launching the EV9 in the US late last year, Kia has handed over 3,839 models in the US. Starting under $55,000, Kia calls its electric family move an “industry wake-up call.”

Despite the strong start, Kia expects the momentum to pick up. Kia currently builds the EV9 in Korea but expects to move production to the US by the end of May.

Tesla executive Rohan Patel clarified some facts about Supercharger NACS access for non-Tesla vehicles like Rivian and Ford.

Patel—Tesla’s Vice President of Public Policy and Business Development—recently replied to a question from Teslavangelist, who questioned the number of Supercharger stalls non-Tesla owners actually had access to with NACS connectors.

Tesla recently opened the Supercharger Network to Ford and Rivian electric vehicles (EVs) through its NACS connecter. Both automakers claim that NACS connectors provide Ford and Rivian owners access to over 15,000 Tesla Supercharger locations. Teslavangelist pointed out that non-Tesla EV owners only have access to V3 and V4 Superchargers, doubting they have access to 15,000 Supercharger stalls.

Tesla is working on “private 5G” infrastructure to be connected to its electric vehicles and Optimus robot.

The automaker was early in including internet connectivity in all its vehicles. There were many reasons for this. It enabled over-the-air software updates and connectivity features, and it also allowed Tesla to collect a lot of data.

Tesla started with 3G connectivity and later updated to 4G LTE, but now, we learn that the automaker is looking to upgrade to 5G.

EVTOL battery analysis reveals unique operating demands. Researchers at the Department of Energy’s Oak Ridge National Laboratory are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically.

These aircraft, commonly called eVTOLs, range from delivery drones to urban air taxis. They are designed to rise into the air like a helicopter and fly using wing-borne lift like an airplane. Compared with helicopters, eVTOLs generally use more rotors spinning at a lower speed, making them both safer and quieter.

The airborne EV’s aren’t just flying cars, and ORNL researchers conclude that eVTOL batteries can’t just be adapted from electric car batteries. So far that has been the dominant approach to the technology, which is mostly in the modeling stage. ORNL researchers took a different tack by evaluating how lithium-ion batteries fare under extremely high power draw.

Now Flinders University researchers have discovered a light-responsive, inexpensive sulfur-derived receptive to low power, visible light lasers—which promises a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.

Details of the novel system have just been published in Angewandte Chemie International Edition, featuring a laser-etched version of the famous “Mona Lisa” painting and micro-Braille printing even smaller than a pin head.

“This could be a way to reduce the need for expensive, specialized equipment, including high-power lasers with hazardous radiation risk, while also using more sustainable materials. For instance, the key polymer is made from low-cost elemental sulfur, an industrial byproduct, and either cyclopentadiene or dicyclopentadiene,” says Matthew Flinders Professor of Chemistry Justin Chalker, from the Flinders University.
