Executive Summary
Cleaner energy is required for economic growth and human development. Sustainable
access to cleaner energy means the ability to satisfy fundamental energy demands and services
through the provision and use of reliable, efficient, economical, and environment friendly energy
resources and technologies.
The study's main objectives are to: (i) assess the current state of household energy use in
one's household area; (ii) identify cost-effective, cleaner, and climate-friendly energy options (on
both the supply and demand sides); (iii) provide sustainable access to cleaner energy services, as
well as the corresponding investment requirements and other costs; and (iv) assess households'
affordability to cost-effective energy access options.
This paper provides a week of daily consumption on one’s household area to determine the
power consumption consumed by each appliances listed. Data gathering tools were used to analyze
various effects on electricity consumption of different variables. As a result of energy conservation
measures implemented, the researchers assessed that the electricity consumption bill had been
reduced.
Introduction
Different energy sources are used by households for their lighting, cooking, and heating
needs. It supports the pursuit of worthwhile endeavors like studying and maintaining good hygiene
and health. Electricity is the preferred energy source in rural and urban families based on the
Household Energy and Consumption Survey (2020) with roughly 75% of rural households and
89% of urban households reporting utilization of electricity.
Electricity is as important and essential today. As of August 2020, the Philippines is
burgeoning with roughly 109 million natives according to the United Nations’ Department of
Economic and Social Affairs. The price of electricity as of November 2022 is 16.8675 peso per
kWh for households which includes all components of the electricity bill such as the cost of power,
distribution and taxes. Innumerable attributes have an impact on household energy efficiency.
This study aims to examine the current state of electrification and the energy used-situation
in one of our groupmate’s household on a daily basis for a week. Additionally, a thorough
evaluation of the possibilities for suggested energy-saving methods was a goal of the study.
Analyzing power usage is crucial for budget management, as well as for the allocation,
efficient use, and conservation of electricity. While limiting your usage of electricity when not
necessary will help you save money on your consumption bill and helps conserved energy.

Proposed Energy Saving Measures
Adjust everyday behavior
Purchase energy efficient appliances
Positioning of the house
Replace air filters
Use natural light
Appliances account for about 13% of all household energy use on average. You should
consider two things when buying an appliance: the initial purchase price and the yearly operating
cost. Even though they might cost more up front, energy-efficient appliances typically have 9–
25% lower operating costs than standard versions.
Use the positioning of your house to your advantage. You can save money and get a
cooler/warmer temperature if used correctly. You can use the natural flow of wind by knowing
where the air flows during a certain time of the year. For example, in the Philippines during
summertime, since you’ll need the cool breeze flowing through your home to alleviate the heat,
you’ll want to have windows and doors that are open for southeasterly winds.
Your cooling system is just one of the many appliances in your house that need filters.
These systems frequently have reminders to change filters on display. You could save money by
doing this in addition to preventing the need for expensive air conditioning maintenance. In fact,
according to a report from the Department of Energy, replacing soiled filters on a regular basis can
save household energy use by up to 15%. This is so that your system won't be overworked and
because clean filters are more effective.
Utilizing light from the sun is a logical strategy to lower your energy consumption since
lighting consumes a large portion of energy expenditures. It is preferable to have windows that
2520
face north and south rather than east and west if you can. As a result, there is less harsh light in the
winter and more glancing light that generates heat.
On the contrary, if researchers are to choose on simplest and most effective way to conserve
electricity, you need to adjust your everyday behavior. You don't absolutely need to go out and
purchase energy-efficient items if you want to decrease energy use in your house and maximize
your energy savings. Simply shutting off lights or appliances when not in use can help you
conserve energy. Doing manual home activities, such as hanging clothes instead of putting them
in the dryer or washing dishes by hand, can also help you use fewer energy-intensive appliances.
Assumptions
In conducting this study, the following assumptions were made it was assumed that:
1) The results of the gathered data upon computing are accurate and verified.
2) Researcher in this study are completely focused on the importance of consumption.
3) The total watts per hour of the washing machine and television are less than those of the
iron and rice cooker.
4) If the energy intervention is utilized, the watts per hour will decrease.

In this graph you will see the Household Energy Consumption and gadget. As you can see
highest energy consumption is Refrigerator and the lowest energy consumption is Radio, if you
notice Refrigerator, Rice cooker and Wi-Fi Router is Same Energy Consumption since Day 1 to 7
and other appliances have different energy consumption due to schedule of use, chores and
weather.

We can see on the graph that the total energy consumption in kilo watt/hour is by adding all
consumption of appliances in each day. As you can see the highest energy consumption is on Day 2 that
have 7.1 Kilowatt or 7159 Watts consumption and the second is Day 1 that have 7.124 Kilowatt or 7124
Watt consumption and the lowest Daily Energy Consumption is Day 5 that only use 4.787 Kilowatt or 4812

Table 3. Total Energy Consumption
As you can see this Graph show the daily cost consumption. To get the total energy cost
consumption is need to use formula C = Quantity x Power rating x Average Hours Used in WattHour but in Naga City we the Energy Rate is by Kilowatt/hour 16.8KWH so to get the total cost
we will use C= (Quantity x Power rating divide by 1000) times to Rate/Kilowatt/hour. As we
notice the highest energy cost consumption is Day 2 and 1 that have P120.27 and P119.68 and the
lowest is Day 5 that only cost P80.84.
Justifications/ Predicated Outcomes
Table 4. Energy Intervention and Expected Outcomes
Energy Intervention
Saving Measures/Intervention
Reduce Appliance Use
Switch off the appliance when they’re not
in use
Defrost your fridge and freezer
Using a washing machine, only use full
loads of clothes.
Clean Electric fan blades
Regularly maintain and check the electric
fan's motors.
Adjust the contrast of the television
Organize your ironing
Expected Outcome
Reducing how regularly you use your
appliances can save you a significant amount
of energy. You can save a significant amount
of electricity by washing fewer loads per
week.
According to the department of energy,
unplugging appliances when they are not in
use could result in weekly savings of 2%.
You can conserve energy and money by
simply unplugging appliances.
It won't use as much energy. To ensure it
operates effectively and saves energy, defrost
at least once every one to two months.
They run less frequently and use less energy
you only use them when they are completely
filled which will lessen the energy cost.
Since its fan won't have to work as hard,
cleaning this will lead to reduced electricity
costs.
To extend the motor's life and reduce
excessive energy consumption, add some oil
within the motor.
The television's contrast can be changed to
save energy consumption, and by setting it to
“standard” will have the lowest power usage
Sort all the clothing into different fabric
categories. Proceed with ironing the pile that
requires the lowest temperature, then move on
to the fabric that requires the most heat.
You'll save time and help in reducing the
consumption of electricity by doing this.
Conclusion
The study intends to determine statistically which among the limited and impacted variables
have an effect on the energy consumption cost on one’s household area.
Electricity is as important and essential today. There are some saving measures that can be
done. A household can implement energy-saving techniques provided that everyone who lives
there consistently uses them. Having a schedule of use of appliances can reduce the energy
consumption and cost.
Monitoring the monthly rate can help to prevent you from having a high bill. Increase of energy
consumption per day can lead considerable amount by the end of month. Unplug appliances if not
use as according to expert, unplugging appliances, gadgets when they are not in use can save 2%
or 1-3 pesos of our weekly consumption.
Recommendations
The researchers recommend alternative saving measures for future researchers.
(I) Installing Solar panels for alternative power source
(II) Checking Appliances for Safety and for maintenance
(III) Unplug Appliances if not use to save.
