B) Develop a problem statement that you are trying to solve. What is the problem you are trying to address?
Ans) Problem Statement: In recent years, household energy usage has played a key role in rising carbon footprint.
C) Brainstorm to develop a list of possible solutions. First, think about the rooms in your house/apartment and evaluate energy usage in each room. Where can you make energy savings? Start with the obvious (e.g., changing light bulbs from incandescent to compact fluorescent, unplugging electronics when not in use), but broaden to include changing the design of your home (e.g., how and when people cook or watch TV). Then, think about the tradeoffs for each. For a list of several ideas to save energy, see the “Ways to Save” tab on your PG&E online account.
Ans) I live in a five-bedroom house. Each family member has their own phones, laptops, and iPads etc. In my house I most likely consume the most energy because I have a TV, computer, PS5, laptops, a fan, and a heater in my room. These electronic devices are sometimes used at the same time. Although a lot of energy does get wasted, we still try to save energy by turning off lights that are not being used or unnecessary. Most rooms in the house can benefit from energy saving in a variety of ways. The following are some suggestions for conserving energy.
a. Turn off superfluous lights; natural lighting is preferable.
b. Use LED light bulbs instead of incandescent bulbs.
c. Turn off and unplug all electrical devices that are not in use.
d. Take shorter showers to save water.
e. Wash your garments in cold water.
f. Don’t open freezers all the time.
g. Replace or clean all filters in your home on a regular basis.
h. Repair any leaks and air-seal your home.
Develop a plan for how you will save energy in your home. In the description of your plan, estimate how much electricity, natural gas, and emissions (in units of kWh, Therms, and lbs of CO2, respectively) you expect to save over the 3-week period with these reductions. Take into account your energy usage over the baseline period. Note that 0.524 lbs of CO2 are emitted per kWh of electricity used, with 13.446 lbs of CO2 emitted per Therm of natural gas used.
Ans) Home energy-saving strategy:
a. Everyone in the house should be mindful of energy-saving actions to conserve energy.
b. Make more use of natural energy.
c. Use energy-saving techniques to replace electrical gadgets.
d. Calculation of a new inverter refrigerator against a non-inverter refrigerator (6.7 cu.ft):
Energy consumption (inverter): 0.4 kW-H/ 24 hours
0.4 kW-H/ 24 hours x 0.524 lbs of CO2 per kW-H = 0.210 lbs of CO2 for 24 hours
0.210 lbs of CO2 for 24 hours x 30 days = 6.29 lbs of CO2 per month
Non-inverter energy consumption: 0.55 kW-H/24 hours
0.55 kW-H/ 24 hours x 0.524 lbs of CO2 per kW-H = 0.288 lbs of CO2 for 24 hours
0.288 lbs of CO2 for 24 hours x 30 days = 8.65 lbs of CO2 per month
As a result, there is a monthly difference of 2.356 lbs of CO2.
