Audit Section Energy #12 09/18/2007 Energy conservation is a growing concern for many people in this day and age. People are becoming more aware of the effects that wasteful habits are having on this planet and more people by the day become aware of global warming. This global warming is produced by power plants burning fossil fuels to generate electricity to power the appliances that we use in everyday life. If we can understand the way we use energy we can begin to see how we can cut down on its use saving us money and the environment. For this Energy Audit I have selected 5 appliances that I normally use in my everyday routine. The first item is my computer. My computer runs at 280 watts per hour (Apple, 2007) and is rarely ever shut off. This means that my computer on average runs about 22 hours a day at 280 watts per hour. Using basic multiplication we realize that my per-day wattage for my computer comes to 6,160 Watts per day (22hrs/day X 280 W/hr). The second appliance I use normally is my desk lamp. This is used when I do homework and sit at my computer so on average about 4 hours a day. The lamp holds a 60-watt bulb meaning the lamp runs at 60 watts an hour for 4 hours a day. This equates to 240 watts of usage per-day from my lamp. A third appliance is my microwave, which is used on a consistent basis. In total for any given day the microwave is on for about 10 minutes. The microwave in our home runs at 1000 watts so the watts per hour measurement would be 1000watts X 1/6 hr or about 167 watts per day. An additional appliance is the digital clock that is running in my room 24 hours a day. The wattage needed to power this clock is a mere 5 watts per hour. This means that the per-day wattage for my alarm clock is 24 hrs X 5 watts or 120 watts per-day, a small number relative to computer usage. The final appliance used daily is the oven. Averaged out over the month the oven is used for about an hour a day. The oven uses 2500 watts per hour on its normal bake setting. This means that the oven uses 2500 watts X 1 hour or 2500 watts per day. We now have our daily wattage requirements for the 5 main appliances in use in my house. The next step is to calculate the amount of wattage required by these appliances per month. We can do this by adding up the watts per day for all appliances and then multiplying them by one month or by multiplying each by one and month then adding them. Using the first method we arrive at: 6,160+240+167+120+2500= 9,187 Watts total per-day. We then take the average month, which is 30 days and multiply the number giving us 275,610 watts per month. We now know the average energy usage per-month so the next step is to calculate the total cost per month. The cost of electricity in Colorado is given to us as $.11 per KW/hr. Taking the 275,610 watts per month and multiplying it by our cost we arrive at 275,610 X ($.11hr/1000KW), which equates to $30.32 per-month expense. Now that we see the energy use per month and the cost per month we can audit the use of our appliances to save money and energy. The first conservation strategy is to decrease all use of appliances. The obvious pro of this conservation strategy is that it will decrease money spent and energy used but the major short fall of this strategy is the lack of consideration it gives to the appliances that are necessary for living. If oven and microwave times are decreased then cooking time is decreased. Without proper nutrition it will become hard to pay attention in class because of the rumbling of stomachs. For this reason this strategy is not suitable for application. A second conservation strategy involves turning off the lights and clocks when they are not used. This too sounds like it might work at first glance but in practice the cons outweigh the pros. The cons are easily seen when thinking about this strategy more in depth. Without the light on during the time I am at my desk I cannot do homework because of the lack of the light and with out the alarm clock plugged in I will not be able to wake up in time for class and both would result in a sudden down spiral of my grades. The third strategy seems to be the best option. This strategy for saving money and energy involves attacking the main use of energy during the day. The computer uses 6160/9187= 67% of my energy for the month and it is on even when I am sleeping. I can turn the computer off when I sleep drastically reducing its running time and allowing for more energy conservation and at the same time saving money. There do not seem to be any cons to this strategy and as a result of this audit I will enact this strategy saving me energy and money. Reference: 1.
