Exploring Hydrocarbon Depletion

But burning wood also releases nasty hydrocarbons and other chemicals that cause cancer. Even the catylytic combustor stoves and the wood gasification furnaces are very dirty heat sources.
Wind and solar are not.

I'm going to call it 'Baha's law' Solar PV panels (which are made of semiconductors) will increase in output by an average of 10 watts every 6 months.
Of course I realize Moore's law just recently fell on it's face but he had a good run:)

Lithium prices are on an upswing:LulaNord wrote:The US has lithium mines sitting idle because right now the price of lithium is too low.
An increasingly precious metalSQM is part of a global scramble to secure supplies of lithium by the world’s largest battery producers, and by end-users such as carmakers. That has made it the world’s hottest commodity. The price of 99%-pure lithium carbonate imported to China more than doubled in the two months to the end of December, to $13,000 a tonne.
Tesla Motors' Dirty Little Secret Is a Major ProblemThe extraction of lithium has significant environmental and social impacts, especially due to water pollution and depletion. In addition, toxic chemicals are needed to process lithium. The release of such chemicals through leaching, spills or air emissions can harm communities, ecosystems and food production. Moreover, lithium extraction inevitably harms the soil and also causes air contamination.
You need to differentiate between batteries in electronics and automotive batteries. Most automotive batteries, lithium or otherwise, are recycled.LulaNord wrote:Lithium recycling probably isn't profitable right now for the same reason, though Toxco and Umicore are both working on recycling lithium batteries, more for the other components than the lithium.
Will a New Glass Battery Accelerate the End of Oil?

John Goodenough, coinventor of the lithium-ion battery, heads a team of researchers
developing the technology that could one day supplant it.
Electric car purchases have been on the rise lately, posting an estimated 60 percent growth rate last year. They’re poised for rapid adoption by 2022, when EVs are projected to cost the same as internal combustion cars. However, these estimates all presume the incumbent lithium-ion battery remains the go-to EV power source. So, when researchers this week at the University of Texas at Austin unveiled a new, promising lithium- or sodium-glass battery technology, it threatened to accelerate even rosy projections for battery-powered cars.
“I think we have the possibility of doing what we’ve been trying to do for the last 20 years,” says John Goodenough, coinventor of the now ubiquitous lithium-ion battery and emeritus professor at the Cockrell School of Engineering at the University of Texas, Austin. “That is, to get an electric car that will be competitive in cost and convenience with the internal combustion engine.” Goodenough added that this new battery technology could also store intermittent solar and wind power on the electric grid.
Goodenough’s new battery can store three times more energy than a comparable lithium-ion battery, according to the very serious Institute of Electrical and Electronic Engineers (IEEE). The new battery also solves some other lithium-ion troubles. Like, it won’t catch fire, so a hoverboard won’t suddenly melt your kid’s Vans as she scoots across the playground. The IEEE also reports that Goodenough’s batteries seem to be able to soak up in minutes as much charge as a lithium-ion battery gets in hours.
