A stereo uses 150 watts of electricity. How much CO2 is produced by using the stereo for 8 hours?

1.2 lb

0.2055 lb

1,644 lb

1.644 lb

mCO₂ = 1.188 lb or simply 1.2 lb

Step-by-step explanation:

We need to use the following expression:

E = P * t

Where:

E: Energy in Kwh

P: Power in Watts

t: time in hours.

Applying this, with the given data we have:

E = 150 * 8

E = 1200 watts . h

Converting this value in kW we have:

E = 1200 watts * 1 kW/1000 watts = 1.2 kWh

In general terms, we have 0.99 pounds of CO₂ emissions per kWh, so with the obtained value we have:

mCO₂ = 0.99 * 1.2
