Part 1: Analyze your energy data at the end of the two-week period. What is the range of values for daily electricity and natural gas usage? What is the average amount used per day? Point out any interesting trends, such as whether more energy is used on the weekend compared to weekdays, and explain any sudden spikes or drop-offs in energy usage along with possible reasons for the findings.
Analysis of Energy Usage
The analysis of household energy consumption over the two-week period reveals significant insights into the daily usage of electricity and natural gas. The average daily electricity usage during this period was 18 kWh, while the average natural gas consumption was approximately 1.5 therms. The data indicates that on average, the household emitted around 29.601 lbs of CO2 per day due to their energy usage, calculated based on the input of carbon emissions per kilowatt-hour and therm of natural gas.
Daily Usage Ranges
The collected data shows the range of daily electricity usage between 5 kWh and 14 kWh and natural gas usage fluctuating with a maximum usage of 1 therm. The lower bound of electricity consumption at 5 kWh occurred during weekdays, while the peak of 14 kWh was registered on November 10, coinciding with specific activities and external influences.
Average Daily Consumption
In terms of averages, the household displayed a consistent pattern with an average daily electricity usage recorded at 6.8 kWh, and the natural gas average at 0.76 therms. These values are surprisingly lower than the average energy usage reported in the Santa Clara region, where households consume more energy.
Trends and Patterns
Upon examining the data, an interesting trend emerged where energy consumption on weekends was higher compared to weekdays. This increase is attributable to family gatherings and recreational activities that require more energy, notably during the evenings. For instance, on weekends, the household would often host social events necessitating the use of heating and additional electrical appliances, such as lighting and electronic devices.
Spikes and Drop-offs in Usage
A notable spike occurred on November 10, where energy usage jumped to 14 kWh. This increase can be attributed to two main factors: the sudden change in weather leading to lowered room temperatures and a family gathering during which a hot pot meal was prepared. Maintaining the heating and utilizing multiple kitchen appliances substantially influenced the overall energy consumption during this day. Additionally, the period between 12 P.M. and 6 P.M. on that same day saw continuous power usage as the household was actively engaged in cooking and accommodating guests. Such specific events indicate that social interactions directly correlate with increased energy usage.
Energy Savings during Conservation Period
Comparing the baseline energy consumption with the subsequent conservation period, the data indicates a slight increase of 10% in electricity usage, totaling 16.75 kWh daily, and a 25% rise in natural gas usage to 1.04 therms. This increase signifies that despite efforts to conserve energy, the household experienced a rise likely related to colder weather and heightened family activities.
CO2 Emissions Observations
Furthermore, the data presents that during the baseline period, the class average for daily CO2 emissions was approximately 19.17 lbs, whereas, during the conservation efforts, this figure increased to 22.76 lbs per day—a concerning rise of 19%. A breakdown of energy savers within the class also reveals various contributions from individual households in mitigating CO2 emissions, with contenders such as Man Guo and Maverick Heebner presenting impressive savings in their respective usages.
Conclusion
The comprehensive analysis of energy usage reveals critical insights into daily consumption patterns, effective energy-saving measures, and interrelations between lifestyle choices and energy consumption. While the household displayed periods of heightened energy usage particularly correlated with social gatherings and weather fluctuations, it is clear that awareness and behavioral changes can promote energy conservation. Continuous monitoring and adjusting for more energy-efficient practices remain vital for reducing carbon footprints and achieving a sustainable living environment.
