To get more knowledge about the harmful fuel that we are using and warn ourselves about it, I chose this article.
Not all energy alternatives are created equal. In fact, some are twice as bad as gasoline from a global warming perspective. Scientists had warned that some vehicles fuel such as liquid coal can cause more harmful than diesel or petrol. The technology to convert coal into liquid fuels is well established. But it is also true that between the production process and burning it in cars, coal-to-liquid fuel produces more than twice the greenhouse gas emissions as gasoline and nearly twice the emissions of ordinary diesel. These are terrible ratios. For example, liquid coal can produce 80% more global warming pollution that petrol. Moreover, fuel like petrol from tar sands is approximately have 14% more global warming potential compared to standard petrol. On the other hand, corn ethanol could be either more polluting or less than petrol, depending on how the corn is grown and the ethanol is produced. The cleanest alternative, the report says, is cellulosic ethanol, made from grass or wood chips. It could cut greenhouse emissions compared with petrol by more than 85%.
To sum up, I think we need to reduce the use of harmful fuel so that we could lower the global warming.
This is too short. You need to have more information in your summary of the article.
