Solar Impulse 2 is about to complete the first round-the-world flight by a plane powered only by the sun. It took off from Cairo on Sunday and is now en route to Abu Dhabi, United Arab Emirates, where the journey began.

At Green House Data in Cheyenne, Wyo., energy efficiency is an obsession.

When someone enters one of the company's secured data vaults, they're asked to pause in the entryway and stomp their shoes on a clear rubber mat with a sticky, glue-like finish.

"Dust is a huge concern of ours," says Art Salazar, the director of operations.

That's because dust makes electronics run hotter, which then means using more electricity to cool them down. For data centers, the goal is to use as little electricity as possible, because it's typically companies' biggest expense.

The Smoggy Seas: Cargo Ships Bring Pollution, Health Risks

"Made in China" labels have multiplied over the past decades — and so have the trade ships docking in East Asian ports.

More shipping containers go through Shanghai than any other port in the world — and most of the world's 10 busiest ports are in China. Asian ports loaded or unloaded almost 50 percent of shipped goods in 2013, according to a U.N. report.

The air conditioner at Jim and Julie Powell's house has been fending off the 100-degree summertime heat for two decades — ever since they came to the Sun City retirement community just west of Phoenix.

"It's been a workhorse," Julie says. "It's probably 20 years old, but it does the job."

Inside, Jim leafs through their summer bills from the power company Arizona Public Service, or APS. He counts: "$183, $262, $250."

Steep, but predictable. Ever since he's heard about a new fee, though, he's begun to worry.

A new study from JP Morgan Chase found that low gas prices led most consumers to spend their money on restaurants and retail, rather than increasing savings or paying down debt.

Oklahoma City’s drop - as a portion of income – was three or four times greater than many other large metro areas, even when regional price differences are factored in, The Journal Record’s Brian Brus reports:

Solar Impulse 2 has landed in Cairo, completing the penultimate leg of its attempt to circumnavigate the globe using only the power of the sun.

The trip over the Mediterranean included a breathtaking flyover of the Pyramids. Check it out:

A quick consultation with Dr. Google will tell you that drinking lots of water — and staying well-hydrated — can help you lose weight.

But is there any truth to this? A new study published in the Annals of Family Medicine adds to the evidence that hydration may play a role in weight management.

In northern New York state, logger Greg Hemmerich and his crew are clearing out an old pasture at the edge of a forest.

"There's a lot of balsam, lot of spruce, thorn apple trees," Hemmerich says. "Ninety percent of this lot is low-grade wood."

In other words, it's no good for furniture or paper or sawmills. But he'll make $80,000 to run the wood through a chipper and truck the chips to a nearby biomass plant.

"Everybody said that green power was supposed to be the wave of the future," Hemmerich says. "So I went full in."
