I have read about how you refuel an electric car is different. You don’t want to power an electric car on a power grid that uses fossil fuel. The goal is to have fully green refueling. I have theorized many things from my posts, such as using solar or wind with hydrogen storage. Also the components used to make batteries have an impact on the environment, unless I am wrong, as I can be wrong. I guess what I read must be wrong and Facebooks independent fact checkers are right. They always are right, and we must follow them. So please do.
Dust that accumulates on solar panels is a major problem, but washing the panels uses huge amounts of water. MIT engineers have now developed a waterless cleaning method to remove dust on solar installations in water-limited regions, improving overall efficiency.
The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.
Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.
The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.
Scientists astounded by performance of sustainable batteries with far-reaching implications for e-vehicles and devices.
Researchers at Bristol have developed high-performance sodium and potassium ion batteries using sustainably sourced cellulose.
Scientists at the Bristol Composites Institute have developed a novel controllable unidirectional ice-templating strategy which can tailor the electrochemical performances of next-generation post-lithium-ion batteries with sustainability and large-scale availability. The paper is published in the journal Advanced Functional Materials.
Starbucks is aiming to capitalize on the rising demand for electric vehicle infrastructure by installing fast chargers at up to 15 coffeehouses this summer, along a 1,350-mile route from Colorado to Washington.
The project, a pilot program with Volvo Cars, aims to build one DC charging station on each 100-mile segment of the western route.
Why install chargers at Starbucks? The coffeehouse chain is betting that it can score business from electric vehicle owners while they wait for their cars to charge — a process that can take a while, depending on the battery and strength of the charger.
USPS has been criticized for not ordering more EVs.
The United States Postal Service announced its initial order of 50,000 next-generation delivery vehicles, 10,019 of which will be battery-electric vehicles. It’s a notable number considering the agency’s resistance to calls for increasing the number of EVs in its future delivery fleet.
Originally, the postal service said it would purchase 165,000 next-generation mail trucks, only 10 percent of which will be battery-electric vehicles. President Joe Biden and congressional Democrats urged the agency to increase the number of EVs, but USPS determined there was no legal reason to change its plans.
Now, the postal service says it will increase its initial order of EVs from 5,000 to 10,019, determining it “makes good sense from an operational and financial perspective.”
Like electric vehicles – traditionally seen as expensive and niche – solar power is now becoming a realistic option for many households, as well as businesses wishing to decarbonise their operations. While the upfront costs of installing a photovoltaic (PV) rooftop system can be expensive, home solar will usually pay for itself within 5–10 years – and then provides the owner with an essentially free, limitless supply of clean energy, decentralised and unaffected by price volatility. Unlike the world’s increasingly scarce, finite supplies of coal, oil and gas, our Sun will continue to shine for another five billion years. Home solar can also be combined with batteries (which, like solar, are rapidly declining in cost) for energy storage at night.
At the utility scale, gigantic solar projects are now emerging in many countries. Recent years have seen the first gigawatt-scale (GW) facilities. The largest has a nameplate capacity of 2.3 GW. China is the world leader, accounting for 30% of all solar electric generation, followed by Europe (21%) and then the USA (16%). The vast majority is produced from PV modules, with a small fraction obtained by concentrated solar power (using mirrors or lenses to concentrate a large area of sunlight onto a receiver).
Following decades of rapid growth, the worldwide installed capacity of solar power has passed 1 TW this month, according to PV Magazine, an international trade publication headquartered in Berlin, Germany. The magazine has based its analysis on data from Bloomberg New Energy Finance (BNEF).
In January 1992, two cosmic objects forever changed our galaxy.
For the first time, we had concrete evidence of extrasolar planets, or exoplanets, orbiting an alien star: two rocky worlds, whirling around a star 2,300 light-years away.
Now, just over 30 years later, that number has exploded. This week, March 21 marked the hugely significant milestone of over 5,000 exoplanets confirmed. To be precise, 5,005 exoplanets are now documented in the NASA exoplanet archive, every one with its own unique characteristics.
Whether it’s photovoltaics or fusion, sooner or later, human civilization must turn to renewable energies. This is deemed inevitable, considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. Much research has been pursued in order to develop alternative sources of energy, most of which use electricity as the main energy carrier. The extensive R&D in renewables has been accompanied by gradual societal changes as the world adopted new products and devices running on renewables. The most striking change has been the rapid adoption of electric vehicles. While they were rarely seen on the roads even 10 years ago, now, millions of electric cars are being sold annually. The electric car market is one of the most rapidly growing sectors.
Unlike traditional cars, which derive energy from the combustion of hydrocarbon fuels, electric vehicles rely on batteries as the storage medium for their energy. For a long time, batteries had far lower energy density than those offered by hydrocarbons, which resulted in very low ranges of early electric vehicles. However, gradual improvement in battery technologies eventually allowed the drive ranges of electric cars to be within acceptable levels in comparison to gasoline-burning cars. It is no understatement that the improvement in battery storage technology was one of the main technical bottlenecks that had to be solved in order to kickstart the current electric vehicle revolution.
However, despite the vast improvements in battery technology, today’s consumers of electric vehicles face another difficulty: slow battery charging speed. Currently, cars take about 10 hours to fully recharge at home. Even the fastest superchargers at the charging stations require up to 20 to 40 minutes to fully recharge the vehicles. This creates additional costs and inconvenience to the customers.
