The Highland Wind Project: Adding 25 Turbines to Southwetern PA
The Highland Wind Project is located in Adams Township in Southwestern Pennsylvania. Electronic transmission passes through the site and will provide a convenient point for interconnection.
Location: Cambria County, Pennsylvania
Project size: 62.5 megawatts
Turbines: 25 Nordex N90 Turbines (each rated at a capacity of 2.5 megawatts)
Commonwealth of Pennsylvania News Release: A former Cambria County strip (coal) mine in Southwestern PA will soon be home to 25 wind turbines generating enough power to meet the needs of 16,000 homes, according to PA Department of Environmental Protection (DEP).
The $140 million Highland wind project in Southwestern PA is expected to be online later this year (2008) and may produce more than 164,000 megawatt hours of power annually. And, because wind power is free of emissions, the project will prevent 400 million pounds of carbon dioxide—a greenhouse gas that contributes to climate change—from reaching the atmosphere.
I inflated my tires this weekend…
It was a sunny day, 80 to 85 degree F, in Pittsburgh this past Saturday. I had just driven several miles before stopping to inflate my tires at a local gas station. My tire pressure should have been higher than normal on such a hot afternoon, right?
Well I could not find the cheap, little tire pressure gauge that used to be in my glove box, so I used the gauge on the hose handle of the tire inflation machine, which I just read is the LEAST accurate gauge you can use. According to the gauge, my tires were 20-25 psi (seriously under-inflated) on a hot and sunny day after driving several miles of errands. The gauge was probably inaccurate, but my tires did look kind of under-inflated based on the slight bulge where the rubber meets the road, a noticeable decline in fuel economy in recent months, and the fact that I hadn’t inflated them since they were newly installed six months ago.
I inflated each tire to about 40 psi, which required a good 10 or 15 seconds per tire with the air compressor. The maximum pressure rating is 44 psi as indicated on the sidewall of my tires, so 40 psi should be fine. After inflating the tires, my ride seems a bit peppier, but it will take a few more tanks of gas to see whether my fuel economy has really improved. According to the EPA, under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.
The most noticeable difference was more aesthetic — I spent $2.50 in quarters to vacuum the interior of my car for the first time in maybe five years.
