The Crown Management : The State of the Nation's Air, and Your Lungs - 1 views

    http://the-crown-management.blogspot.com/2013/06/the-state-of-nations-air-and-your-lungs.html In most places, the quality of air in America is better than ever. As China remains blanketed by an ever-thickening haze, we in the United States can be grateful of one thing: The air is getting cleaner in most parts. The American Lung Association reported in its State of the Air 2013 that 18 cities have lower dust pollution compared to previous years, while 16 had their lowest figures ever. Nevertheless, the improvement is not that widespread. About 25 million Americans live in conditions of harmful levels of ozone and particle pollution. Around 131 million people (42%) live with either type of unhealthful environment. California's busy and highly-populated metros rank badly in the rankings, consistently topping the five most-polluted metros by ozone, year-round and short-term particulate pollution. Bakersfield, the highest for particulates among 277 metros, fares worst of all although it has already improved. In general, 119 counties have levels of ozone that affect the health of citizens with "aggravated asthma, difficulty breathing, cardiovascular harm and lower birth weight". Particulate levels in 58 counties are such that they "increase risks of heart attacks, strokes and emergency room visits for asthma and cardiovascular disease". Cities, such as Salt Lake City and Fairbanks, Alaska, experience more frequent short-term spikes in pollution. Out of 25 cities that had the worst short-term problems, 14 recorded more poor days than in previous reports of the "State of the Air". According to the report, some cities experienced higher pollution arising from increased burning of wood and other fuels for heating during winter, especially with the use of highly-polluting indoor wood-stoves or outdoor wood-boilers. Of the cleanest cities, New Mexico proudly ranks third and fifth for least particulates (Santa Fe and Farmington), Wyoming has another (Cheyenne), then

Could You Run Your City on Oats? - 1 views

    During a region-wide blackout in 2011, the lights at the University of California, San Diego, stayed on. Thanks to its campus microgrid, UCSD has achieved near self-sufficiency in energy generation and distribution, lowered energy costs, made energy provision more reliable, and proven that computerized management can easily integrate new sources of energy-like solar panels-into a utility grid. "It's almost like plug and play. You decide what you want to feed in in terms of alternative energy sources, and as long as you put in this advanced micro-grid that can manage [energy] and modulate when you use it, it becomes a very effective tool," says Gary Matthews, vice chancellor for resource management and planning. The UC-San Diego microgrid has evolved over time. When the campus was under construction in the 1960s, university leaders decided to manage buildings as a system, rather than connecting them individually to the local power grid. About 12 years ago, the university added a cogeneration plant. Today, some 200 energy meters monitor energy in individual buildings, and a computerized management system allows facilities staff to fine-tune energy delivery depending on use patterns. Researchers and corporations are closely watching the electric grid, which has become a living demonstration of how to manage a diverse energy mix that includes solar panels, fuels cells and electric car charging stations. The microgrid saves hundreds of thousands of dollars each month, according to the university, and protects laboratory and hospital space from the threat of power outages. Although it's expensive to install an energy management system this comprehensive, utility companies nationwide are starting to invest in household 'smart' meters they hope will make energy delivery more responsive to demand.
