SpaceX launches, more lawsuits for Tesla, Elon Musk will pay his taxes.
SpaceX completes two Falcon 9 missions in 15 hours, Tesla is hit with lawsuits from former employees and shareholders, Elon Musk is prepared to pay his taxes.
With new major spending packages investing billions of dollars in electric vehicles in the U.S., some analysts have raised concerns over how green the electric vehicle industry actually is, focusing particularly on indirect emissions caused within the supply chains of the vehicle components and the fuels used to power electricity that charges the vehicles.
But a recent study from the Yale School of the Environment published in Nature Communications found that the total indirect emissions from electric vehicles pale in comparison to the indirect emissions from fossil fuel-powered vehicles. This is in addition to the direct emissions from combusting fossil fuels —either at the tailpipe for conventional vehicles or at the power plant smokestack for electricity generation—showing electric vehicles have a clear advantage emissions-wise over conventional vehicles.
“The surprising element was how much lower the emissions of electric vehicles were,” says postdoctoral associate Stephanie Weber. “The supply chain for combustion vehicles is just so dirty that electric vehicles can’t surpass them, even when you factor in indirect emissions.”

This summer Tesla finally decided to jump into the housing market, to provide products for the upcoming homes being built by a home builder called E-home. With the technological advances that Tesla has shown. It will be interesting to see what products Tesla will provide for these homes.
This could be an innovation that might shake at the housing markets and an agreement was made between Tesla and the real estate developer. Tesla would supply Powerwalls electric, Vehicle chargers, and Solar panels to all set E-home Inc, which is a subsidiary of international incorporated.
When interviewed, the corporation stated that the Tesla products will be installed in 20 new single-family homes, which will be at the north park community in porter Texas. Also, E-home is having to build 100 single-family homes by the end of 2021 within Texas.
You may not see them coming, but the effects of climate change are starting to be felt in certain parts of the world. An example of this is the destruction of several coral reefs around the globe in recent years. As devastating as that sounds, it is only the prologue to a long list of potentially catastrophic events yet to arrive. In the long term, climate change threatens to eventually drive humans towards extinction. Therefore, while little steps, like planting more trees and turning out lightbulbs when not in use, are certainly useful, bigger steps are needed to fend off the devastating effects of climate change.
An internal combustion engine is one of the prime contributors to climate change-causing carbon emissions. Such engines produce large quantities of nitrogen oxide, carbon monoxide and other hydrocarbons that harm the environment and cause respiratory disorders in individuals. Due to these—and many more—reasons, electric vehicles, or EVs, need to replace the ones with traditional combustion engines.
EV owners can save about US$700 a year on fuel costs alone. Also, the maintenance expenses of EVs are lower than those of standard vehicles. So, owning EVs can help them save money and reduce their extreme reliance on fossil fuel, thereby slowing down its inevitable depletion from the earth. Additionally, EVs are incredibly efficient as they only consume approximately 25–40 kWh per 100 miles. Most importantly, EVs reduce CO2 emissions by nearly 178 million kg. What’s more, despite the high fuel efficiency and smaller carbon footprint, EVs can outperform vehicles with traditional combustion engines easily.
And it’s a hybrid mix of hydrogen and electric power.
Global mining company Anglo American is experimenting with hydrogen to power the giant mining trucks.
Mining trucks consume 35.3 gallons (134 liters) of diesel per hour with their enormous weight of around 220 metric tonnes and therefore emitting vast amounts of carbon dioxide into the atmosphere.

As the electric car revolution ramps up, so does the need for critical minerals used in batteries, such as graphite. According to Benchmark Mineral Intelligence, there will be a global graphite deficit starting in 2022, and demand from the battery sector is expected to rise 30% annually until 2030. The US has no manufacturing plants that can supply automotive-grade graphite at scale. Meanwhile, China controls 84% of the global supply. Electrek spoke with Don Baxter, CEO of Ceylon Graphite, about how graphite is used in EVs, the supply chain issue, and how EV battery manufacturers can successfully source the vital mineral.
Electrek: How is graphite used in battery electric vehicles?
Don Baxter: Processed graphite comprises 95% of the anode (negative electrode) of lithium-ion batteries that power EVs, whereas the cathode (positive electrode) is made up of various materials such as nickel and cobalt.
An international team of experts has collected data on metal halide perovskite solar cells from more than 15,000 publications and developed a database with visualization options and analysis tools. The database is open source and provides an overview of the rapidly growing knowledge as well as the open questions in this exciting class of materials. The study was initiated by HZB scientist Dr. Eva Unger and implemented and coordinated by her postdoc Jesper Jacobsson.
Halide perovskites have huge potential for solar cells and other optoelectronic applications. Solar cells based on metal-organic perovskites achieve efficiencies of more than 25 percent, they can be produced cheaply and with minimal energy consumption, but still require improvements in terms of stability and reliability. In recent years, research on this class of materials has boomed, producing a flood of results that is almost impossible to keep track of by traditional means. Under the keyword “perovskite solar,” more than 19,000 publications had already been entered in the Web of Science (spring 2021).
Now, 95 experts from more than 30 international research institutions have designed a database to systematically record findings on perovskite semiconductors. The data are prepared according to the FAIR principles, i.e. they are findable, accessible, interoperable and reusable. By reading the existing literature, the experts have collected more than 42,000 individual data sets, in which the data can be filtered and displayed according to various criteria such as material compositions or component type. Researchers from several teams at HZB were involved in this Herculean task.
