Electric cars What the million-mile battery means for electric cars

The Economist It is mainly about greater reliability Science & technology Aug 1st 2020 edition As every mobile-phone owner knows, after a year or so the battery starts to fade and the beast needs recharging more frequently. That is a nuisance, but a phone’s batteries can be replaced fairly cheaply—or the whole handset traded in for the latest model. An electric car, …

Energy storage set to compete in US wholesale markets following landmark ruling

By Andy Colthorpe, Jul 13, 2020,  0 Distributed energy storage facilities in the US are set to join wholesale markets and compete to provide grid services after what’s described as the “single most important act” for the energy transition so far. The United States Court of Appeal in the District of Columbia ruled last week against petitioning from the National Association …

Renewables+Storage operating as virtual power generation get more renewables on the grid & can provide demand response automatically, eliminating the need for day-ahead planning, respond immediately to price signals, shift loads, or aggregate other distributed energy resources

Renewables + storage, operating as virtual power plants often cover a wider area than microgrids (which also island) and are flexible enough to expand or contract the area in which they operate, depending on market conditions. They serve the main grid, while microgrids don’t always provide services to the main grid. Virtual power plants can get more renewables on the …

‘Million-mile’ batteries are coming. Are they a revolution?

By Maddie Stone on Jul 6, 2020, Grist Electric vehicles (EVs) have a clear environmental advantage over their gas-guzzling counterparts, but when it comes to longevity, the two are in a dead heat. Two hundred thousand miles is considered a good, long run for a car built today, regardless of whether it’s powered by a lithium battery or an internal combustion engine. But if …

Battery prices have plummeted since 2010 and are still dropping

Ars Technica, May 2020 In 2010, a lithium-ion battery pack with 1 kWh of capacity—enough to power an electric car for three or four miles—cost more than $1,000. By 2019, the figure had fallen to $156, according to data compiled by BloombergNEF. That’s the result of a virtuous circle where better, cheaper batteries expand the market, which in turn drives investments that …

Already cost-effective, no-regrets actions to get us to 90 percent zero carbon electricity while reducing wholesale electricity costs 10 percent

The technology-neutral policies laid out in this paper are no-regrets actions to get us to 90 percent zero carbon electricity while reducing wholesale electricity costs 10 percent. The United States could deliver 90% clean electricity nationwide by 2035, without the need for new fossil fuel plants, according to a study released today from the University of California, Berkeley — with the right …

Electricity prices to drop after reaching 100% renewable target. Publicly owned utilities have been moving faster and offering cheaper electricity.

Australia: ACT electricity prices to drop after reaching 100% renewable target, RenewEconomy, June 2020 (article further down) ** There is a “flexibility and nimbleness” to a small, city-owned utility. These characteristics will help the transition to clean energy — a fact made apparent by some of the cities that have already achieved their 100% renewable goals, like Burlington, Vt. and Georgetown, Texas. Both …

More than 1 in 3 rooftops in US are suitable for solar. By investing $450 billion in rooftop solar, the federal government could slash energy bills for Americans, cut air pollution, and create over 3.7 million jobs. The government could also get paid back.

John Farrell, ILSR, April 10, 2020 Congress should consider a huge opportunity to pay Americans that pays back: solar rooftops. Somewhat more than one in three home or business rooftops in America is suitable for solar: sunny with sufficient space to host a few panels. By investing $450 billion in rooftop solar, the federal government could slash energy bills for …

How Low Can Energy Storage Go? Lots & Lots Lower!

April 13th, 2020 by Tina Casey, Clean Technica The renewable energy transition sure makes for some strange bedfellows these days. The latest example is a new energy storage breakthrough from the University of California’s Loker Hydrocarbon Research Institute in Los Angeles. The Loker Institute launched in the 1970s with a focus on fossil fuels and petrochemicals — think OPEC oil crisis and …
