THE University of Derby is officially ‘First Class’ when it comes to being environmentally responsible, new figures show.
It is ranked 22nd out of 142 UK universities in the 2011 People & Planet Green League – which each year grades higher education institutions on their environmental and ethical performance – published in The Guardian newspaper today (June 7). Only 31 of the universities received a First Class grading; with others getting a 2:1, 2:2, Third or Fail.
Derby’s position has shot up more than 20 points from 48th in the 2010 report, when it was then given a healthy 2:1 grade.
The People & Planet League report assesses universities’ environmental performance and commitment using 13 criteria including environmental policy, carbon management, ethical procurement (of supplies), staff and student engagement, and (disposal of) waste and recycling.
Significant improvements have been made in the University of Derby’s environmental performance in the last few years.

Granted Im not in a great mood today with the loss of a dear pet, but what is this crap? In the Phoenix area alone this happens many times a year and I have to wonder, is there some form of code that says; Im leaving my child for you to torture and kill. Mother buys the line that she/he fell while putting away toys, but later became unresponsive and then Mama will look devastated as the news cameras roll. That done, perhaps the two adults can clean the slate of previous leg-spreading experiments, providing a fresh start for another doomed relationship. Ole boy might do some jail time, but...

The chart shows that the solar component of BGS comes to a whopping 0.09 cents per kilowatt hour, out of a total BGS cost of 11.259 cents per kilowatt hour. That's nine-hundredth of one cent due to solar. I'm not too good at math but my calculator says
