The world’s wind-power capacity increased 113-fold over the past 20 years. As installations increase, turbines become more efficient and electricity prices decline. For a growing number of countries, this means wind power is now cheaper than conventional energy sources, even without government subsidies.
View this interactive graphic by David Yanofsky to see which countries lead in wind and when wind power will reach price parity with conventional forms of electricity generation.Read more »
As nations install more solar-generated electricity, it becomes less expensive to produce. In several countries, the learning curve has already led to prices competitive with conventional power. See this interactive graphic by our Bloomberg colleague David Yanofsky to see when solar power might reach price parity with conventional forms of electricity generation.

It's a fact of London roads that pedestrians, cyclists and motorists all hate each other at times. And given the standards of cycling, driving and walking in the U.K. capital, there's good reason.
There's also good reason to think drivers could pave over these tensions just by thinking more about their wallets.Read more »
The March 11, 2011, earthquake and tsunami killed 25,000 people in Japan and caused the worst nuclear disaster since the 1986 Chernobyl meltdown. A report from a nuclear engineers' group today adds fuel to a debate about the catastrophe's lingering effects.
The "off-site health consequences of the Fukushima Dai-Ichi accident may ultimately be negligible," reports the American Nuclear Society, an organization of nuclear engineers and scientists. The radiation plumes from the accident haven't caused direct deaths. There have been no measurable health consequences to workers and the public, which means that "confirming health effects will take more time," the group said.Read more »
If you've never seen offshore wind turbines, it's hard to appreciate their scale. Blades can exceed 85 yards in length, their tips sweeping arcs almost 180 yards in diameter. They twirl atop towers a football field high and can produce enough electricity to power more than 1,500 homes.
Now imagine where you'd build something that size.Read more »
Seventeen thousand and three. That’s how many coffee shops Starbucks operated as of October 2011, in 55 countries, from Argentina to Vietnam. To make those stores more sustainable, the company must manage everything from tropical agronomy to the recyclable fiber in each paper cup.
Jim Hanna is director of environmental impact at the world’s largest coffee-shop chain, and oversees Starbucks’ progress toward cutting energy and water use by 25 percent in company-owned stores by 2015, compared to 2008 levels. He spoke last week with Siobhan Wagner, analyst at Bloomberg New Energy Finance.Read more »
Welcome back to the Griddle, our top picks from the week's Bloomberg Sustainability stories. Many people associate "Clorox" with century-old brand of bleach. How times change. Clorox Co. (CLX) is now aiming for a $300 million health-care products and services business, mostly through acquisitions. The company wants to build on the success of Burt's Bees, the sustainable skin-care line that helped develop a natural products standard for its industry. Clorox is one of a growing number of companies pursuing sustainability practices both in the products it sells and by integrating its financial and sustainability reports to give investors a longer-term view of the full costs and benefits of its operations.

Apple is the world's biggest company by market size, the biggest buyer of semi-conductors, the biggest maker of smartphones, and, if you include iPads, the biggest maker of personal computers.
The company is about to add a few more superlatives to the list: America's biggest producer of on-site solar and fuel-cell power.Read more »
If it seems like the chattering classes are talking about carbon dioxide less than they were a couple of years ago, that's because they are. Even drivers of the public climate conversation, such as the Carbon Disclosure Project, have begun to ask if "water is the new carbon." As the group's chairman Paul Dickinson has said, "If climate is the shark, then water is the teeth."
The issue of water security on a heating planet emerged quickly after U.S. and international efforts to reel in carbon dioxide emissions fizzled in 2009. The Carbon Disclosure Project itself launched a new water program in 2010. At the same time, a water-and-energy specialist named Peter Gleick found the spotlight, having thought about the issue for more than a quarter century. He even came up with a memorable phrase, "peak water," with a definition behind it, in 2010. Water as an issue engaged many of the same experts – and much of the same rhetoric – previously claimed by carbon.Read more »
