Sewage and industrial sludge is being managed as a liability. Current outdated regulations and technologies focus on the least-expensive means of the sludge disposal. Sludge management needs to be redirected toward the recovery of energy and chemicals embedded in the sludge and guided by the principals based on the current scientific findings and technology. Environmental and demographic considerations need to play an important role in this new approach geared toward sustainable and energy-efficient waste management practices.

There are two situations which do not require you to be heating your home: when it is warm and when you are not at home. Since it is still a bit chilly outside, you may want to consider setting up a routine of turning down the set temperature on your thermostat when you head out in the morning and when you go to bed.
Some large electronics can use as much energy as a light bulb while in "stanby" mode, meaning you should unplug them when you leave the house or know you won’t use them for awhile.

But it’s worth the switch — not only are CFLs equal in light quality, they last way longer and will save you hundreds of dollars over their lifetime.
