Dear our beloved crying planet…
Dear our beloved crying planet… I read an article last week in “The Gazette”, a local English paper here in Montreal Canada. It was titled “Time is running out” and was written by Peter G. Brown. He is a professor in the school of the Environment...
Easy Ways to Save Energy
With this fall's spike in oil and natural gas prices and the further impact Hurricane Katrina will have on this winter's heating oil supplies, it's become more important than ever to make sure our homes are as energy-efficient as possible. ...
Environmentally-Friendly Earth Homes
What are "Earth Homes?" Earth homes are houses that are basically constructed from the earth. Some earth homes are built from adobe, mud, straw or even underground as an earth-sheltered home. Environmentally friendly, earth homes are easy to warm...

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.
