Energy is Cheap
Cooling, heating and electronic appliances all need
considerable energy to run. It is estimated that homes
today need 37 percent more energy to be powered than
homes in the eighties, little thanks to explosion in
smarter home appliances.
Tropical Regions are the energy hub of the earth. This
assertion can be appreciated going by the established
facts on scientifically proven evidences. According to
Budyko 1980. Solar energy is the only source of energy
for nearly all natural processes occurring in the
biosphere. It can be safely concluded since all energy is
sourced from the sun and the tropical regions has great
natural supply of this energy, it is therefore an important
energy hub of the world. This can be well established
going by the distribution of other naturally free energy
sources in the world such as Fossil fuel, wind, bio mass,
coal and running water.
However, it is a misnomer to observe that tropical
regions economy of the
world do not adequately exploit this area of comparative
advantage to accelerate their development process. In
tropical regions home energy need accounts for a
considerable amount of national energy need. Ignorance
and lack of technical know-how are responsible for how
many home dwellers spend hard earned income on
artificial means of meeting their home energy need.
With ample supply of free natural energy, home dwellers
can save tons of money taking advantage of these natural
sources of energy for home use. Appropriate technical
know-how makes meeting home energy need, a fun
while saving a lot of disposable income and resources.
What kicks in at this junction is the need to perpetually
look for a way to intelligently consume energy. This new
way of life shall promoted development in sustainable
way-i.e not harmful to the environment.
A striking feature in all these is that these ways comprise
of strategies which range from mere common sense to
simple appropriate technologies which are not
necessarily rocket science in nature.
This book critically dug into home design, building,
maintenance and operational, to bring into limelight
these grey areas. Contemporary home technologies,
some of them as old as 100 years were examined. Ways
of operations and maintenance to enhance cost saving of
energy are suggested. New technologies are reviewed
and presented while the future energy saving
technologies are previewed and introduced.
Contemporary home based technologies such as
thermostat, solar energy, wind turbine, air-conditioning
and refrigeration, cooking gas, pumping machine among
many others are duly evaluated.
