Energy Exit Ticket
| # | Answer |
|---|---|
| 1 | Information collected about energy use, production, or transfer that can be stored, analyzed, or visualized by a computer system. |
| 2 | A smart meter, sensor, or data logger. |
| 3 | It makes it easier to organize, calculate, and compare energy values. |
| 4 | Kilowatt-hour (kWh). |
| 5 | Power is the rate of using energy, while energy is the total amount used over time. |
| 6 | Variables store values like voltage, current, time, or energy so the program can calculate and update results. |
| 7 | A temperature reading, light level, current measurement, or motion signal. |
| 8 | An alert, dashboard graph, notification, or automatic switch-off command. |
| 9 | To detect physical conditions and convert them into data for a computer to use. |
| 10 | It helps people quickly see patterns, trends, peaks, and unusual usage. |
| 11 | Automatically adjust heating or cooling to improve comfort and reduce energy use. |
| 12 | Using less energy to achieve the same or better result. |
| 13 | Time-series data. |
| 14 | It can make graphs, averages, and predictions inaccurate. |
| 15 | It provides step-by-step instructions for collecting, analyzing, or responding to energy data. |
| 16 | Solar, wind, hydroelectric, or geothermal energy. |
| 17 | To automatically adjust devices based on sensor data and rules. |
| 18 | It can turn devices off or reduce usage when certain conditions are met. |
| 19 | A database keeps data organized and available for long-term access and analysis. |
| 20 | Trends, changes, peaks, and periods of low usage. |
| 21 | The interval affects how detailed and accurate the data is; too large may miss changes, and too small may create unnecessary data. |
| 22 | Too many computers left on, inefficient settings, or running energy-intensive software. |
| 23 | Real-time data is collected and used immediately; historical data was collected earlier and stored for later analysis. |
| 24 | To reduce wasted electricity by turning lights off when rooms are empty or when enough daylight is available. |
| 25 | Using resources in a way that meets current needs while reducing harm to the environment and preserving resources for the future. |
| 26 | The unit, what is being measured, and possibly the time and location of the measurement. |
| 27 | It ensures the sensor readings are accurate and reliable. |
| 28 | A set value that triggers an action when data goes above or below it. |
| 29 | It could find patterns in energy data and make predictions or recommendations for reducing use. |
| 30 | It can detect problems early, reducing energy waste and preventing equipment failure. |
| 31 | To determine whether the change actually improved efficiency. |
| 32 | Energy = Power × Time. |
| 33 | 600 watt-hours. |
| 34 | Because kilowatt-hours are commonly used for reporting larger amounts of energy and for utility bills. |
| 35 | Advantage: detailed data. Disadvantage: more storage and processing are needed. |
| 36 | It allows the app to send or receive data from another service or device. |
| 37 | Numbers provide exact values, while charts make patterns easier to understand. |
| 38 | Privacy, because the data may reveal habits and routines. |
| 39 | If hacked, the system could be manipulated, disrupted, or expose sensitive data. |
| 40 | Use better thresholds, filtering, or more than one sensor before triggering an alert. |
| 41 | Use a script or management tool to shut down or sleep idle computers automatically after a set time. |
| 42 | It can use fewer processing steps, lowering CPU activity and saving battery life. |
| 43 | It can process data close to the source, reducing delay and network traffic. |
| 44 | It can hide short spikes or important patterns in usage. |
| 45 | If the room is empty for 10 minutes and it is daytime, turn off lights and reduce HVAC output. |
| 46 | Compare sensor data before and after implementation and check whether expected actions occur under test conditions. |
| 47 | High-quality data, enough examples, relevant features, and proper testing. |
| 48 | Increasing efficiency may reduce heating or cooling to save energy, but that can make people feel less comfortable. |
| 49 | Solar generation, building energy use, energy saved, and cost over time. |
| 50 | Example: Use motion and light sensors as data sources; if the room is empty or sunlight is sufficient, the system turns off lights and lowers power use; the expected outcome is reduced electricity consumption without affecting learning. |
