The secret behind Elon Musk’s goal of selling 20 million Tesla’s a year by 2030 lies in its pioneering battery technology. The good news is that by using bigger cells and a new process to dry-coat electrodes, Tesla could halve the cost of a Model Y battery, saving more than 8% of the car’s U.S. starting price, battery experts with ties to the company said. The bad news is that it’s only halfway there, according to 12 experts close to Tesla or familiar with its new technology. That’s because the dry-coating technique used…

CLIMATEWIRE | The sudden unveiling of the Senate climate bill two weeks ago launched a race among emissions modelers. Their calculations, and extrapolations, estimated that the “Inflation Reduction Act” would spur a rapid deceleration of carbon dioxide — about a 40 percent reduction over seven years. But are they right? Emissions modeling comes with caveats and limitations. Here’s one: It can take more than a decade to build an interstate transmission line to connect renewable energy generation to major metropolitan…

At a student orientation in 2002, Ron Gonen told his professors and peers at Columbia Business School that he hoped to build a business that was both financially successful and environmentally sustainable. The response was “dead silence,” he recalls. “People thought I was there by mistake.”Twenty years on, Mr. Gonen, 47, counts Microsoft, Nestlé, PepsiCo and Unileveramong his investors as the founder and CEO of Closed Loop Partners, a firm that invests in the technology and infrastructure needed to boost recycling rates…

On top of the disruptions and stress of COVID-19 lockdowns, isolation from their schools, their friends and (for many) their extended families, tens of thousands of Australian families have also seen their communities ravaged by fires and floods.…

Credit: CC0 Public Domain Extant studies have noted that China's ability to peak carbon emissions by 2030 has something to do with the economic growth rate and suggested a slowdown in economic growth in China to help peak carbon emissions. However, none of them gives a quantitative account for such a relationship. …

New research suggests that the brewing method and the sex of the drinker may be important to coffee’s link with raised cholesterol.Widest gender difference seen for espresso; narrowest for plunger (cafetière) coffee.The sex of the drinker, as well as the brewing method, may be key to coffee’s link with raised cholesterol, a known risk factor for heart disease, suggests research published on May 10, 2022, in the open access journal Open Heart.Drinking espresso was associated with the widest gender difference in cholesterol…

So far, President Biden’s legacy on climate change is pretty insubstantial. There’s time to change that if he can quickly make much better use of his Environmental Protection Agency (EPA). The president put nearly all his hopes for climate action into passing his Build Back Better legislation through Congress. That bill would have spent $550 billion on clean energy and electrified transit. It failed to garner a majority in the Senate, and due to continuing reticence about the measure on the part of more conservative…
