A Simple Way To Offset the Environmental Effects of Driving Your Car
We all love our cars. They give us the freedom to come and go as we please, to get to work, to visit family and friends, to go shopping...on our own schedule. But automobiles also effect the environment by polluting the air we breathe and, in...
Efficiency Equals Reduction
Efficiency Equals Reduction (400 words) Imagine that if at the grocery store the person bagging your purchases left empty, unused spaces in each bag causing you to carry 10 instead of 5 bags out to your car then into your home. You would be...
Photovoltaic Systems - Energy from the Sky
As people search for alternatives to fossil fuel energy, solar
energy emerges as one of the cleanest and most practical sources
of electricity. Solar panels can be installed on rooftops or any
area that receives a lot of sunshine. The solar...
Since Katrina, the Environment Is Front-Page News
Ever since the end of August, when Hurricane Katrina devastated
the major American city of New Orleans and the coastlines of
Louisiana, Mississippi, and parts of Alabama, the consequences
of environmental degradation have been front-page...
Toxic Mold & Disease
Asthma has increased 300 percent in children in the past ten years. Research by WHO, in Germany, finds prostate cancer, breast cancer, and other cancers increasing due to mold-related problems. Mold is the number one health problem with one in...

Solar Cooling - Air-Conditioning From the Sun
At first glance, solar cooling looks like an oxymoron. However,
the same energy that can provide heat in the wintertime can also
provide cooling during the summer.
Several passive cooling systems have been developed and tested.
At their simplest, they rely on a coolant that absorbs and
dissipates heat from the house. This could be a pool of water on
the rooftop which absorbs seat from the inside of the house as
it evaporates on exposure to the sun.
More sophisticated passive solar cooling systems have a solar
collector which is shaded during the daytime. A storage medium
collects heat during the day and dissipates it at night by
exposing the solar collector to the cool night air.
Since the solar collector must be shaded, a retractable awning
or overhang extension can be installed. Since the system can be
reversed in the winter months, it is important that the solar
collector can be exposed to sunshine if needed.
Solar panels can also be used to operate traditional air
conditioners. As it
happens, the periods of intense heat
correspond to the periods of peak electricity production from
photovoltaic cells. As long as you have solar panels which
generate sufficient to electricity, you can operate air
conditioners at no cost.
Solar cooling that does not take advantage of high technology is
another possibility. The Romans used a system of running water
to cool down exterior walls of their houses. The heat of the sun
causes the water to evaporate and dissipate the heat within the
house. This kind of system can be used on walls or on rooftops.
Heating and cooling are two of the biggest expenses for most
households. Using solar energy to reduce this expense makes
sense financially as well as ecologically. The less dependent we
are on fossil fuels for heating and cooling the cleaner the
environment will be.
