 Suppose an air conditioner is left on stand-by 24 hours a day for 284 days.  How many pounds of CO2 would be produced?  Round you answer to the nearest tenth. 

To calculate how many pounds of CO2 would be produced, we need more information, such as:

1. The energy consumption of the air conditioner in stand-by mode, usually measured in watts (W) or kilowatts (kW).
2. The emission factor for electricity in pounds of CO2 per kilowatt-hour (kWh), which varies depending on the energy source.

Assuming this information is provided, the steps to calculate the total CO2 produced are as follows:

### Step 1: Convert standby time to total hours.
Since the air conditioner is on stand-by for 24 hours a day for 284 days:
\[
\text{Total hours} = 24 \, \text{hours/day} \times 284 \, \text{days} = 6,816 \, \text{hours}
\]

### Step 2: Calculate energy consumption.
Let's assume the air conditioner consumes \( P \) kilowatts (kW) in standby mode. The total energy consumed in kilowatt-hours (kWh) is:
\[
\text{Total energy consumed} = P \, \text{kW} \times 6,816 \, \text{hours}
\]

### Step 3: Estimate CO2 emissions.
If the emission factor is \( EF \) pounds of CO2 per kWh, then the total CO2 produced is:
\[
\text{Total CO2 produced} = \text{Total energy consumed} \times EF = (P \times 6,816) \times EF
\]

### Final Answer:
To give a more precise answer, we would need the power consumption (\( P \)) of the air conditioner in standby mode and the emission factor (\( EF \)) for your location's electricity source.

Do you have the power consumption details or the emission factor?

**Follow-up questions:**
1. What is the standby power usage of the air conditioner?
2. Do you know the emission factor for your electricity grid?
3. How efficient is your air conditioner in standby mode compared to regular operation?
4. Could using a timer or energy-saving settings reduce stand-by time?
5. Would switching to renewable energy reduce the CO2 emissions from electricity?

**Tip:** Reducing standby power consumption by unplugging appliances can cut down on unnecessary energy use and CO2 emissions.
