...quiz: what source of power doesn't come out of the ground, doesn't burn and isn't radioactive? Hint: it contributed the most new electricity generation to the U.S. grid...
...green talk and growth in wind power - it accounted for 42% of all new electricity generation added to the U.S. grid last year - wind still makes up less than 3% of America's total electricity generation. Even at current rates of growth, that figure is unlikely to change soon. The question is, Will wind ever produce enough power to satisfy America's energy needs? (Watch TIME's video "The Truth About Wind Power...
...richest wind resources tend to be far from the densely populated coastal areas that need the most electricity. Another problem is intermittency - even in Chicago, there are days when the wind doesn't below. But both those hurdles can be sidestepped by building a more modern and supercharged electrical grid, one capable of funneling wind-generated electricity from the middle of the country to the coasts. A dense and more connected network can also compensate for intermittency, with wind turbines in one part of the country backing up those in another. (See 10 things to do in Chicago...
...Tysons is unincorporated and is overseen at the county level.) The government won't mandate these changes. Rather, property owners will apply individually to increase the scale or density of their holdings, to tear down or add to what is already standing, and work together to hammer out a grid of streets to replace the maddening squiggles of private, dead-end roads - a grid that Alcorn says is as important as the Metrorail in battling congestion...
...scrap the car dealership and other low-rise buildings sitting on the 20 or so acres it owns in Tysons to create a mixed-use development near a soon-to-be-built train station. Aaron Georgelas, the group's managing partner, is happy to donate land to the street grid, since the county will allow him to build higher because of it. He also knows that tearing down revenue-generating buildings to put up new ones - even if they're three times as large - is a gamble, particularly in the current economic climate. "You very well could be handing that...
