Electricity that powers our homes in most
countries comes from nonrenewable energy sources. These nonrenewable
sources however are decreasing at an alarming rate.Before these
resources are depleted, man must starts to use other sources that are
renewable. This website deals with energy at home and
renewable energy. This webpage concentrates on the usage of electrical
consumption in the student's household and how its consumption is
compared with his friends in the local community, and perhaps in other
community. The findings can be posted and share with other countries as
knowledge across the globe. It will also provides some useful
information, links and activities to renewable energy sources. |

Using energy at home
This module has six sections and each section requires you to carry out
some fun and investigating activities.
Section 1
What is energy?
This section draws the attention of the student towards the fundamental
sources of energy. It starts with a fun cross-word puzzle.
Section 2
How is energy use at
home?
This section concentrates on the uses of electrical energy at home and
how the energy cost spent by each appliance/device. It also motivates
the student to save electricity take may eventually lead to change of
life-style. In this section, students may relate with other issues like
“carbon footprint” and “green-house effect”
Section 3
This section gives the opportunity for the students to visualize
different energy consumption in their household by drawing pie-charts
and suggesting ways to minimize the usage and energy consumption.
Section 4
This section deals with an important component in every household, the
light bulb. Here the student is given different common light bulbs and
are to work in a group collaboratively. The students are to gather some
important information about each of the different types of light bulb
and discuss and explain why a certain type of bulb is preferred.
Section 5
This section gives the students to role play as a house builder. It
challenged the student to find a best solution to create an energy
saving house. This activity requires the students to defend and explain
why his decision on the house is built as such.
Section 6
This section merely gives the student an opportunity to sum-up what he
has learned and how his new knowledge can realistically be carried out
so as to have an impact to the people around him or her.
Objectives of the
module are:
v
to enable the
students to list the different types of non-renewable energy and
renewable energy
v
to guide the students
to calculate the energy consumption at home
v
to motivate the
students to realize the important of energy usage from various
perspective through discussion
v
to compare the energy
consumptions of different types of appliances use at home
v
to calculate the
impact of using energy star appliances
v
to discuss how the
each household are able to consume less energy
v
To provide a
progressive pathway in which energy is used, from personal to local,
from local to other countries and its impact in the global scale. In Malaysia, most households use mainly the three types of bulbs to light
up homes and may not be the same in your country. Share your experience
on the mode of lighting that is common in your country.
