Tesla makes good on South Australia promise with world’s largest Lithium ion battery

Comments Off on Tesla makes good on South Australia promise with world’s largest Lithium ion battery

Elon Musk is a man of his word. In March the Tesla CEO tweeted a promise that he would help South Australia solve its energy woes in 100 days with a new power storage system – or give the whole thing away for free. Now he’s following up on that promise, having inked a deal with the State government to build the world’s largest Lithium ion battery. If he can’t finish in 100 days, the energy titan estimates he’ll lose a cool $50 million. “There is certainly some risk, because this will be the largest battery installation in the world by a significant margin … the next biggest battery in the world is 30 megawatts,” Musk said at a recent press conference. According to local news sites , Musk said that Tesla will make an effort to make the 100MW battery storage system aesthetically-pleasing so that it can double as a tourist attraction. This will be the highest power battery system in the world by a factor of 3. Australia rocks!! https://t.co/c1DD7xtC90 — Elon Musk (@elonmusk) July 7, 2017 He said it will look like a series of white obelisks. Tesla’s 129MWh battery system will store energy – produced by a nearby wind farm still under construction by the French company Neoen, providing greater stability and a backup power source when necessary. “You can essentially charge up the battery packs when you have excess power when the cost of production is very low,” Musk said, “…and then discharge it when the cost of power production is high, and this effectively lowers the average cost to the end customer.” Via ABC

Stanford study says fossil-fueled cars will vanish in 8 years as big oil collapses

Comments Off on Stanford study says fossil-fueled cars will vanish in 8 years as big oil collapses

A new study published by Stanford University suggests that fossil-fueled cars will vanish within eight years – and citizens will have no choice but to invest in electric vehicles or similar technologies. This is because the cost of electric vehicles – including cars, buses, and trucks – will ultimately decrease, resulting in the collapse of the petroleum industry. Led by Stanford University economist Tony Seba, the report has caused spasms of anxiety within the oil industry . Entitled “Rethinking Transportation 2020-2030,” it details how people will ultimately switch to self-driving electric vehicles, as they are ten times cheaper to maintain than cars that run on fossil fuels and have a near-zero marginal cost of fuel. Additionally, EVs have an expected lifespan of 1 million miles. In comparison, most fossil-based cars barely last 200,000 miles. Seba predicts that in less than a decade, it will become very difficult for consumers to find petrol stations, spares or mechanics knowledgeable enough to fix combustion engines. His ultimate premise is that modern-day car dealerships will disappear by 2024 as the long-term price of oil falls to $25 USD a barrel. Those who cling to their outdated cars will probably have to pay to dispose of them in the future, says Seba. In the author’s own words, there will be a “mass stranding of existing vehicles.” Related: Iceland’s “Thor” volcano power plant can generate 10X more energy than oil or gas wells The Sanford researcher is also confident that within the next decade, humans will predominantly rely on self-driving vehicles as they are significantly less dangerous. “We are on the cusp of one of the fastest, deepest, most consequential disruptions of transportation in history,” said Seba. “Internal combustion engine vehicles will enter a vicious cycle of increasing costs. What the cost curve says is that by 2025 all new vehicles will be electric , all new buses, all new cars, all new tractors, all new vans, anything that moves on wheels will be electric, globally.” The Professor estimates that the “tipping point” will occur in the next two to three years when EV batteries surpass 200 miles and electric car prices plummet to $30,000 USD. By 2022, the low-end models will be sold for as low as $20,000. Following that, it will be the death of big oil . + Stanford Via Financial Post Images via Pixabay

India wants to increase solar output by renting rooftops

Comments Off on India wants to increase solar output by renting rooftops

In a push to expand the country’s solar power capabilities, Indian electric companies are urging potential customers to rent out their rooftops to host solar panels. Their first target? Large industrial and commercial electricity consumers. Not only do the companies that host the panels end up with a significant discount on their power bill compared to the cost of local utilities, but developers save money on the most expensive aspect of solar development — the cost of purchasing large amounts of land to host their renewable energy projects .
