Tales from Spain: baseload renewable energy means hope in the fight against global warming
Hola, amigos y amigas. I write to you from Spain. I’m here courtesy of the Catalan government, who brought me in to explain the California solar market to local solar companies. Why does Spain care about California? Spanish solar companies are going through a really difficult time right now. Briefly, the story goes like this. […]

World's biggest solar power tower to open in Spain
The world's biggest solar tower will open early this year in Spain. The race for leadership in the next generation of solar power is taking off.
The U.K. Guardian reports that in the desert 20 miles outside Seville, the Spanish company Abengoa will be deploying over 1,000 sun-tracking mirrors -- each "about half the size of a tennis court" -- to superheat water to 260°C to drive a steam turbine and generate 20MW of electricity.
Concentrated solar power (CSP) technology, as it is known, is seen by many as a simpler, cheaper and more efficient way to harness the sun's energy than other methods such as photovoltaic (PV) panels.
Spain is placing a huge bet on CSP to meet their renewable energy and carbon targets:

Ring in the new with a ‘natural’ bottle of bubbly
Fewer chemicals in our sparkling wines? We’ll drink to that. Nothing says festive quite like the pop of a chilled bottle of bubbly. But while sparkling wine delivers a party in a glass, things are typically less thrilling out in the field. Like most wine, bubbly tends to come from grapes grown in large monocrops […]

Spain experiencing severe drought due to climate change
Warming-driven desertification is spreading. Australia has gotten the most attention, but Spain is also turning into a desert. As Time reported:
Spain is in the grip of its worst drought in a century as a result of climate change -- this year's total rainfall, for example, has been 40 percent lower than average for the equivalent period, and the country's reservoirs are, on average, only 30 percent full. The reservoirs serving Barcelona are only 20 percent full, and without significant rainfall, supplies of drinking water will likely run dry by October.

‘Heart-healthy’ pork from pigs with bad hearts
I live for this sort of stuff: Guys in white lab coats got to tinkering with pig DNA, hoping to conjure up pork rich in “heart-healthy” omega-3 fatty acids. Here’s what they did: A team from the University of Pittsburgh a first transferred the roundworm gene–fat-1–to pig foetal cells. After that, a team from the […]

Viral epidemic hits Mediterranean
Striped dolphins in the Spanish Mediterranean are under attack from a virus similar to measles that could kill roughly 75,000 of the creatures before the disease loses steam.
Authorities confirmed the disease, Morbillivirus, was also responsible for a plague that killed hundreds of thousands of dolphins in the early 1990s and also recently affected the Canary Island right whale population.
This is definitely not the year for dolphins -- perhaps you remember the reports late last year of the Yangtze River dolphin effectively becoming extinct. Human impacts, including industrial pollution, boat traffic, and overfishing, were to blame. A video surfaced earlier this summer showing Brazilian fishermen killing 83 dolphins for kicks.
True, this virus may be a natural phenomenon despite its disastrous potential. Things like poaching, pollution and overfishing can be prevented and helped -- and should be.

Solar thermal power deserves more attention, due to its lower cost and relative ease of storage
Solar thermal power is back! Solar thermal gets less attention than its sexier cousin -- high-tech photovoltaics -- but has two big advantages. First, it is much cheaper than PV. Second, it captures energy in a form that is much easier to store -- heat -- typically with mirrored surfaces that concentrate sunlight onto a receiver that heats a liquid (which is then used to make steam to drive a turbine).
Back in the 1980s, Luz International was the sole commercial developer of U.S. solar thermal electric projects. The company built nine solar plants, totaling 355 MW of capacity, in California's Mojave desert. Luz filed for bankruptcy in 1991 for a variety of reasons detailed in this Sandia report.

Man, that’s the worst headline ever
Here’s a short but fascinating BBC story about a ginormous (11MW, with plans for expansion) concentrated-solar power plant in Seville, Spain — the first commercial concentrated-solar plant in Europe. Hundreds of mirrors reflect sunlight at a single point at the top of a tower, where the heat boils water for stream that drives a generator. […]

Pedro Arrojo-Agudo has started a new water culture in the Old World
Economics professor Pedro Arrojo-Agudo, who teaches at the University of Zaragoza in Spain, is using his academic expertise to battle a monster: the National Hydrological Plan, a $25 billion project that would build 120 dams on the Ebro River. The dams would submerge entire towns along Spain’s second-longest river, displace tens of thousands of rice […]
