Empire State Building Goes Green

Empire State Building Going GreenOne of the biggest challenges in greening our cities lies in reducing the energy consumption of existing buildings. Newer constructions are built with efficiency in mind, but older buildings (such as the iconic Empire State Building) were erected without even a passing thought to carbon emissions.

The Clinton Climate Initiative has been working with cities around the world to implement large scale projects to reduce emissions and energy consumption, and has just announced the $20 million dollar eco-renovation of the Empire State Building, reports CleanTechnica. The tallest building in New York will receive new, triple-glazed, insulated windows (to increase efficiency in the summer and winter), an upgraded lighting system, new furnaces, and updated air conditioning systems, according to Clean Technica. The renovations are expected to lower the building's energy consumption by 38-percent.

The improvements are expected to pay for themselves within approximately three years of their completion, projected to occur by the end of 2010. Additional improvements made to tenant areas will continue through 2013, and may yield further reductions in energy consumption.

Somehow, Los Angeles Tops EPA's Most Energy-Efficient City List


An unlikely trio of cities can lay claim to the United States' most energy-efficient buildings, thanks to a report in USA Today.

Los Angeles, San Francisco, and Houston have been named by the EPA as having the most efficient buildings in the U.S., with annual energy savings of $87.2 million, $83.8 million, and $70.6 million, respectively.

While we would love to jump on the bandwagon and slap these three cities on their backs, we have a little bit more sense than that. After all, anybody who has visited Los Angeles and Houston is well aware that these two places aren't exactly "green." They are, however, massive cities, not only in population, but in sheer geographical sprawl, as well. So, of course, each of these cities has more green buildings than Cheyenne, Wyoming, or Hattiesburg, Mississippi, or Lancaster, Pennsylvania. But that's because they have a lot more buildings, in general.

And while some of those buildings may be green, most of them aren't. We're not exactly students of the environment, but we're certainly confident in saying that Cheyenne, Hattiesburg, and Lancaster -- all put together -- have less of a negative environmental impact than Los Angeles alone.

LED Light Bulbs That Last 60 Years to Get Cheaper

Super-Efficient LED Bulbs to Get Cheaper
Those old-school incandescent bulbs you grew up with are on their way out, deemed too inefficient for a continued life in today's eco-friendly society. But their replacements, compact flourescent (CFL), have their own share of issues. Some people find that the next-gen bulbs give them headaches, and since each one contains a bit of mercury they aren't exactly green themselves. For that reason, many have seen LEDs as a possible replacement, but they have their issues, too, primary among them being cost. That could change thanks to a British professor's newest tech, which could make the bulbs considerably cheaper.

LEDs are small and don't give off much light, but they last for literally decades (like, 60 years) and give off virtually no heat, making them three times more efficient than the twisty CFL bulbs. Professor Colin Humphreys at Cambridge University has come up with a way to make them far cheaper than normal, creating a more efficient way to produce gallium nitride, a material required for the production of LEDs. His discovery could pave the way to LED bulbs that cost less than $5 a pop. However, we're still at least a few years away before these could go into mass production, meaning you're going to have to keep hitting the Asprin or guiltily using your old incandescent bulbs.

Texas Wind Power Initiative to Blow Other States Away


Oh sure, Rock Port, Missouri managed to snag the title of being "100% wind powered," but Texas' new plan will make the Show Me state's gusty initiatives look awfully weak. Officials at the Public Utility Commission recently okayed a plan to "build billions of dollars worth of new transmission lines to bring pollution-free energy from West Texas to urban areas."

The ginormous Lone Star state is already the nation's leader in wind power, but when said plan is fully implemented (pending final approval), it'll produce more wind energy than the next closest 14 states combined. Granted, customers will be paying a touch more ($4 per month is the current estimate) for all this clean energy, but pundits assert that the cost is minor when looking at just how much this will help out Mother Earth. Look for everything to go live in four to five years, barring any unforeseen setbacks. [Source: MSNBC]
