    I wanted to talk to you about the differences in the white LED s. And they also come in different sizes. The numbers that you see before the size is pretty much how big the LED is in millimeters. But keep in mind other sizes that may have come in different applications.

  • Public alleyways are being repaved with materials that are permeable to water. The white oak, the state tree of Illinois, has been banned from city planting lists, and swamp oaks and sweet gum trees from the South have been given new priority. Thermal radar is being used to map the city’s hottest spots, which are then targets for pavement removal and the addition of vegetation to roofs. And air-conditioners are being considered for all 750 public schools, which until now have been heated but rarely cooled.
  • Cities adapt or they go away,” said Aaron N. Durnbaugh, deputy commissioner of Chicago’s Department of Environment.
  • Insurance companies are applying pressure in high-risk areas, essentially saying adapt or pay higher premiums — especially in urban and commercial areas.

  • Civic Consulting Alliance, a nonprofit organization that builds pro bono teams of business experts. In this case, the alliance convinced consulting firms to donate $14 million worth of hours to projects like designing an electric car infrastructure and planning how to move the city toward zero waste.
  • The city’s 13,000 concrete alleyways were originally built without drainage and are a nightmare every time it rains. Storm water pours off the hard surfaces and routinely floods basements and renders low-lying roads and underpasses unusable.
  • Chicago spends over $10 million a year planting roughly 2,200 trees. From 1991 to 2008, the city added so many that officials estimate tree cover increased to 17.6 percent from 11 percent. The goal is to exceed 23 percent this decade.

  • the White House is standing behind a goal that could genuinely transform the nation’s automotive fleet: putting one million electric vehicles on the road by 2015.
  • But many of the electric vehicles that will count toward President Obama’s goal won’t run on electricity alone. They will combine batteries, electric motors and internal-combustion engines to use as little gasoline as possible while still doing everything Americans expect their cars to do. Electrification is not an all-or-nothing proposition
  • Department of Transportation statistics show that 78 percent of Americans commute 40 miles or fewer a day, so most people who drive a Volt won’t need to burn any gas on a normal day.

  • Obama administration already supports incentives to encourage drivers to buy electric cars, and it has devoted $2.4 billion in stimulus money to the development of a domestic electric-car industry.
  • existing $7,500 tax credit
  • If we gut domestic clean-energy research, scientists in China or Germany or Japan will finish this work. But it would be far better to stick with the program we’ve begun — financing research into better batteries while deploying vehicles that replace gasoline with electricity as much as possible — and prove that when it comes to energy, America can, in fact, learn from its mistakes.
