Save a hill in West Virginia

Whether or not you believe in global warming, Google Earth can quickly take you for example to Kayford Mountain, West Virginia where you can see for yourself the devastation of Mountaintop removal mining (MTR). Here is what you can do.

Mr. Hewlett and Mr. Packard have always been lovers of the outdoors and HP gives you advice on how you can conserve energy and help protect the earth when you use our products. The day I am writing this, HP has joined the Climate Savers Computing Initiative, which within two and a half years will cut greenhouse gas emissions in an amount equal to shutting down twenty 500-megawatt coal-fired power plants. Follow the above two links to learn what you can do to use less power with your computer system.

If you design computer devices, make sure you specify a switched power supply with power factor correction. Power factor correction adds only little to your power supply cost. If you do not know how to do it, there are excellent engineering support services here in the Silicon Valley, like for example Power Factor 1.

If you design software, make sure your code is efficient, because color algorithms can be processor hogs. In modern computers, processors are dynamically clocked down when the full power is not required. Optimize your code and give your customers a quieter computer with longer battery life … and help save a hill in West Virginia.
