What Will it Take to Harness the Wind?
For the United States to reach any major goals for renewable energy, it's going to need major infrastructure development—not only does it have to build the wind farms where it's windy, it also has to update the grid so it can move that power to the nation's population centers.
Yesterday, the Wall Street Journal assured that this could cost a fortune—as much as the stimulus package Congress is currently bickering over. But don't give up hope yet. The Journal cites a study by several regional power authorities, who were commissioned by the Department of Energy to study what it would take for the U.S. to draw 20 percent of its energy from wind by 2024.
The transmission system, with 15,000 miles of new lines, would take up to $100 billion, plus the $720 billion to build the actual wind farms. What the Journal fails to mention is that the agencies' report also presents a sister scenario in which the U.S. moves to only 5 percent wind power by the same year. It's still expensive, just a little less so than the 20 percent scenario, and the energy production costs are higher.
The Journal also fails to mention the report's explicitly stated caveats that it didn't take any offshore wind development into account, nor did it consider other ways of moving wind power or making it more regional. The New York Times hits it closer to the mark: updating the grid so that we can move to more wind power will be difficult, no doubt, but that's no reason to imply that it can't be done.
The ability to speak clearly, succinctly, and powerfully is easier than you think
The ability to communicate effectively can make or break a person's assessment of your intelligence, competence, and authenticity.
The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.
- The study measured the stiffness of blood vessels in middle-aged patients over time.
- Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
- The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
What defines a dark horse? The all-important decision to pursue fulfillment and excellence.
When we first set the Dark Horse Project in motion, fulfillment was the last thing on our minds. We were hoping to uncover specific and possibly idiosyncratic study methods, learning techniques, and rehearsal regimes that dark horses used to attain excellence. Our training made us resistant to ambiguous variables that were difficult to quantify, and personal fulfillment seemed downright foggy. But our training also taught us never to ignore the evidence, no matter how much it violated our expectations.
