6. Replace incandescent lights with compact fluorescent lamps (CFLs). Compact fluorescent lamps can save three-quartersof the electricity used by incandescent lamps. During the life span of a CFL, it uses about $22 in electricity. Incandescent bulbs do not last nearly as long as their counterparts. You would need ten incandescent bulbs to equal the life span of a CFL. These ten bulbs will cost you more than $80 in electricity. You would basically be cutting electricity prices in that area down by almost $60.

7. If you are thinking of buying a new refrigerator, don't leave the old one plugged in, in the basement, as a backup for party supplies and liquid refreshment. If you do choose to keep a spare one, you are looking at about $50-$100 in electricity costs a year to do so. As a rule of thumb, purchase one refrigerator that will be of adequate size to encompass all your refrigeration needs. 

 Saving Our Environment

Our natural environment consists of both living and non-living components, which are commonly referred to as just 'the environment.' The key constitutes of our environment include two main areas. The complete ecological units functioning as a natural overall structure with minimum human interference is the first main area of the environment. This eco system consists of animals, vegetation, rocks, atmosphere and microorganisms.

The second area includes everything that is not human-originated, but are natural forces - but there are no clear lines drawn here. These forces include energy, radiation, magnetism, air, water, climate and electricity.

What nature had already provided and what man has created are in sharp contrast. What humans have created is called the built environment. At any place, only if the influence of humans is negligible can it be called a natural environment.

However, a natural environment and a wilderness are not the same. There are a lot of other factors that must be taken to consideration before an area can be called a natural environment, unlike in the case of a wilderness, which is any area without any human interference.

We all know that natural environments are dwindling now. Whether it is the melting of the glaciers or the rising temperatures everywhere or the erratic rains, human interference has thrown a major obstacle in the way of the natural climate and environment. This is what natural environmentalist groups are campaigning against. They are trying to make sure that what there is left is kept intact, and new areas that can be classified as natural environments are created, as well as new wildernesses.
