UNIT 3 Science DB - Essay Example

Day I started my day today a bit early than usual. The Sun was yet to rise. I switched on the bulb and put off the air conditioner. Both of thesethings were an example of residential use of energy in the form of electricity. After my daily routine, I went to gym and had 20 minutes of jogging on electrical walker. This, along with the lighting in gym and the lift that took me there, were commercial use of electricity. Back home, I prepared my breakfast. I used LPG gas stove for the same. It is again an example of residential use of energy in form of liquid petroleum gas for heating my breakfast.

In fact whatever energy I am using at my home is residential use of energy. Now it was time to go college. I picked up my bike to reach there. In this process I used energy for transportation and fuel was petrol. College classroom lighting was also using commercial electricity. After the day I reached back home and after dinner and couple of hours on internet, went to sleep. My primary source of energy at home is electricity.Day 2 /Day 3: Daily activities of these days were almost same, apart from my visit to hospital on day three.

There also lightings, lifts, ACs and other medical equipment were running on electricity supplied by electric company but backup was also available in form of generators running on diesel. One more form of energy which I saw here, was that for heating water. They used solar panels for heating it.In above experiences, main supplier for my daily energy needs was our electrical company, and I could not have experience of largest energy end use i.e. industrial, with highest expected growth rate of 2.

4 percent per year (International Energy Outlook, 2006, p.1).Our electricity company is MAHAGENCO. As per its website, it generates electricity mostly from its Thermal Power Plants which uses Coal as the main fuel. This fact is in line with world over trend, wherein 40 percent of electricity is produced from Coal as a main fuel (International Energy Outlook, 2006, p.67). It has other generation plants based on hydroelectricity also.If I look back on my energy consumption, there are various areas where in I can make certain changes to make my self more energy efficient.

This can be achieved by reducing my gross energy consumption as well as using more and more alternative energy sources. By reducing my energy consumption I would be contributing, whatever little it may be, towards reducing anthropogenic emissions of carbon dioxide, which is estimated to grow at an average rate of 2.1 percent per year from 2003 to 2030 (International Energy Outlook, 2006, p.72), and associated green house effects. By using renewable energy sources I would be putting lesser stress on finite fossil fuels.

So, instead of using an electric walker, I am going to jog in the park. As far as possible, I would use public transport for going college. And finally, if possible, I will have solar panels installed at my rooftop for heating my bathtub.ReferenceInternational energy outlook 2006.
