Because
renewable energy is a large topic that would take years to completely
dissect, it is often easier to understand aspects of it by coming
to an understanding of the different ways how it is used.
One of the ways that this is most often used is through a passive
home design. But before understanding this, the basics of being able
to understand how heat moves and how it can be stored is imperative.
In a nutshell, heat works by moving from a warmer surface to a cooler
one, back and forth, until the difference in temperature no longer
exists. This is the main law that is taken into consideration when
a passive solar home is designed and laid out.
There are a few different aspects that are then more thoroughly explored
when a person who seeks to use renewable energy in creating a passive
home design gets to the point where he is ready to keep the project
rolling.
• Radiation – One of the big things that can help in such
a process is radiation. There are two main types of radiation that
play a big role in passive solar home design. The first is solar radiation
and the second is infrared radiation.
Inside of a home or a business, infrared radiation occurs simply when
something that is warm moves to heat up something in the home that
is cooler.
The best and most common way for solar radiation to be transmitted
is through windows. This is what many of the homes that use renewable
energy through means such as a passive home design include many large
windows in the home.
Infrared radiation and solar radiation are actually very closely related.
For example, even though radiation can enter a home through the windows
as solar radiation, once it reaches an object inside of the home it
then becomes infrared radiation instead.
• Conduction – In addition to radiation, the process of
conduction is also very important to those who seek to use renewable
energy inside of their homes or places of work. Conduction refers
to the way heat is able to move from one material to the next. The
heat essentially travels from molecule to molecule until it is completely
able to heat up an item.
This process can go very fast or very slow. This depends on how large
the item is that is being heated. What the outside source of heat
does is spread to other nearby molecules. This spreading of the heat
encourages the molecule to vigorously bounce around. This friction
causes even more heat.
If a person is interested in using renewable energy in a non-passive
way, this is of course still possible and actually more common.
Although many people tend to think of solar energy as possibly the
only form of renewable energy that they can use, this is far from
the truth.
Those who have attempted to learn to understand how to best use this
energy as well as learn from which sources it can best be collected
have found that there are many different sources available to them.
Wind energy is one of the other popular types of alternative energy
that many people have turned to in the last several years. While the
use of this kind of energy is still far from being prevalent, it certainly
has become more noticeable recently and there’s no disputing
the fact that renewable energy. is now more popular than it ever was
before.
