Nowadays more people concern about the relationship between energy and the Internet.Google engineers accounted it into numbers and got the result that an average query of Google search uses about 1 kJ of energy and emits about 0.2 grams of carbon dioxide.Let’s take comparisons with some other activities to see a clearer picture.
| Activity | Google Searches |
| CO2 emissions of an average daily newspaper (PDF) (100% recycled paper) | 850 |
| A glass of orange juice | 1,050 |
One load of dishes in an EnergyStar dishwasher (PDF) | 5,100 |
| A five mile trip in the average U.S. automobile | 10,000 |
| A cheeseburger | 15,000 |
| Electricity consumed by the average U.S. household in one month | 3,100,000 |
You may feel happy to see such a result that Google uses less energy to conduct every search.I think that’s all because Google puts energy saving into its priority and again it has a dedicated team of engineers to work on it in order to set a group of most efficient data centres in the world.Google claims that now it uses less than half of the industry average and it continues to find a further way to reduce the usage of energy.
In 2007 Google co-founded the Climate Savers Computing Initiative, a non-profit organization committed to reducing global CO2 emissions from the operation of computers by 54 million tons a year by 2010.I think we all need to have a look there to learn how to reduce the environmental impact of our own computer use.
Google is green and we could be green too.
