Food Studies: Old-world innovation	29.11.2011	Gristmill
by Kathryn Tomajan. Food Studies features the voices of volunteer student bloggers from a variety of different food- and agriculture-related programs at universities around the world. You can explore the full series here . Vapor escapes through mountains of white rocks. Steam billows out of a huge cauldron in the distance. The smell of sulfur stings my nose, and the ground i s hot to the touch. It's easy to imagine I'm on another planet, or in some science fiction novel. But where I am is Tuscany, the Italian region famous for its beautiful landscapes and classic cuisine. And food producers here are harnessing vapor, steam and sunlight to make the traditional products of the region. It's not sci-fi, but it might just be the future of food. Italy's volcanic past gave Tuscany its rolling hills and fertile soil, and now it's providing the region with a source of renewable energy. Power plants dot the landscape and steam pipelines stretch along the gentle slopes. As of 2008, approximately 13 ...

Google phases out clean energy R&D in favor of deployment	24.11.2011	Gristmill
by Stephen Lacey. Cross-posted from Climate Progress . Media incorrectly report Google is abandoning renewables. In fact, the company is increasing clean energy investments. Buried at the bottom of an innocuous “spring cleaning” post on Google’s blog yesterday, the internet giant made a very important announcement: It will stop funding its Renewable Energy Cheaper than Coal (RE<C) initiative. But that’s not the whole story. And if you believe the headlines—“ Google Abandons Renewable Energy Push ” or “ Are Google’s Green Days Over? ”—you might think this is a negative development. But if you look at the details, it’s a story about how the company is adapting to a changing market and actually increasing investments in renewables. Announced in 2007 by Google, RE<C was focused on driving down the cost of renewable electricity (mostly solar and geothermal) to meet the cost of generating electricity from ...

Clever! Geothermal Power Plants Could be a Massive Source of Lithium for Batteries	18.11.2011	TreeHugger
Demand for lithium is growing very rapidly thanks to portable electronics and electric vehicles. What if we could get a lot of lithium cheaply, without building new mines?

Startup to Capture Lithium from Geothermal Plants	16.11.2011	Technology Review Feed - Tech Review Top Stories
The approach could boost U.S. lithium production—just as demand is set to soar with increased electric-vehicle usage. As portable electronics get more popular and the market for electric vehicles takes off, demand for lithium—a critical element in rechargeable lithium-ion batteries—could soar. Yet just two countries, Chile and Australia, dominate global lithium production.

We could replace coal power with geothermal — ten times over	8.11.2011	Grist News
by Sarah Laskow. The United States has so many viable spots for producing geothermal energy -- i.e. tapping into the heat of the Earth’s core to generate power -- that the country's geothermal potential is equivalent to "ten times the amount of coal capacity in place today," according to Climate Progress . Southern Methodist University developed this geothermal map in partnership with Google. The western half of the country has the greatest potential for geothermal development, but there are hot spots elsewhere -- check out that orange spot in the Northeast. That's in coal country and provides a way to keep jobs while shutting down dirty coal mines and power plants. ...

Here’s a win-win: Geothermal power can make lithium for electric vehicles	1.10.2011	Grist News
by Christopher Mims. Existing geothermal power plants are powered by a hot brine from deep within the earth's crust, which is just lousy with dissolved minerals -- literally "half the periodic table," reports Scientific American . One of those elements is lithium, which can be extracted from the geothermal fluid that existing power plants in California's Salton Sea are already pulling out of the ground. This is remarkable on many levels at once. 1. The world is desperately in need of more sources of the “rare earth” elements that are required to build advanced batteries and just about everything else in cleantech. 2. Usual hard-rock mining of lithium is terribly environmentally destructive, whereas this process isn't, because it relies on already-existing reservoirs of hot water to extract the mineral from rocks down below. 3. This process turns geothermal power, already an excellent source of emissions-free base load power, into a potential source of ...

Canadian geothermal could produce a million times as much electricity as the country needs	19.9.2011	Grist News
by Christopher Mims. The federal Geological Survey of Canada says that the total available geothermal resource in that country could produce a million times as much electricity as the entire country uses, or well more than enough to light up all of planet earth many times over. Iceland has already gone all-out in exploiting its own geothermal resources, with the end result that 99 percent of its electricity is produced domestically from renewables, in a combination of both hydro and geothermal power. So it's not like there's any question whether this resource can actually be exploited. The main reason it hasn't been pursued more avidly is that exploration for geothermal resources is still in some ways a young industry. One expert told me, not long ago, that it was about where exploring for oil was about 50 years ago. Which means it's possible to spend millions of dollars drilling a well and still come up empty. Investment banks don't like those odds. But when you ...

Half of all geothermal energy is left over from birth of solar system, say scientists	19.7.2011	Grist News
by Christopher Mims. Well, hello there, enormous quantities of heat that's just beneath our feet and could potentially be tapped to provide enormous amounts of base-load electricity! Where'd YOU come from? The birth of the planet, you say? No sh*t! Using this gigantic underground, water-filled neutrino detector , scientists have finally gotten a better idea of exactly where the Earth's heat comes from: Turns out only half of that heat comes from radioactive decay deep within the planet (which was previously our best guess). The other half may actually be leftover heat from when the Earth and its buddies were formed. It's like Earth is a burning hot ember removed from the fire that forged it, slowly radiating its heat into the vast, cold reaches of outer space. To the tune of 44 trillion watts of heat energy, all day, every day. When we drill into the earth's surface to tap that heat energy for geothermal power, we're siphoning off a teeny tiny bit of that ...

Peggy Holroyd: Geothermal Energy: A No-Brainer for Canada?	13.7.2011	Green on HuffingtonPost.com
How much geothermal electricity is generated in Canada today? None, zip, nada! Yet the geothermal resource potential in Canada could exceed one million times Canada's current electricity consumption. On paper you'd think geothermal energy would be a no-brainer for Canada. In spite of a lack of political leadership in Canada, interest in geothermal is starting to emerge. The resource exists, the environmental benefits are significant, the costs can be low, it works in remote locations and geothermal energy plays well with new clean-energy grids. Now is the time to turn up the heat on geothermal energy development in Canada.
