Will Green Cars Save The Environment??

Nowdays, people are comming up a lot of new ideas to save the environment, including "green cars". Now let me explain what are exactly "green cars".

Basically green cars, or Hybrid Cars are powered by the following:
Power sources include:
On-board or out-board rechargeable energy storage system (RESS)
Gasoline or Diesel fuel
Hydrogen
Compressed air
Human powered e.g. pedaling or rowing
Wind
Compressed or liquefied natural gas
Solar
Coal, wood or other solid combustibles

In fact none of these power sources are truly convenient.Also, when we use electricity powered cars, we may run out of electricity halfway and be stuck in the middle of a road.Also, when we charge our car battery in our homes we are still indirectly polluting the environmrent as our electricity supply are directly from power stations. And when we demand for more electricity, the power stations will need to burn more fuel and release more pollutants into the air.

In my opinion, I therefore think that Hybrid Cars are not very convenient and also more expensive and, will still pollute the environmemt. So I think that we should not depend so much on private transports but instead switch to public transports.

"Why Did I Do It?"

I regretted disobeying Ms Narwin, and now, where am I? Washington Academy. Actually I do not know how to sing the national anthem, but i did it deliberately. I refused to admit the truth as Ms Narwin is really treating me unfairly which cause me to have a grudge of her. I was thinking of a way to "punish" her. When she tried stop me from causing a disturbance, I thought that she had no right to do that, so I defied and even wrongly accuse her. Now, I am "forced" to sing the national anthem while my previous school, Harrison High, forbids it! At this moment, I finally appreciate the things Ms Narwin and other staff had done for me. If I had the chace to go back to Harrison High, I would surely apologise to Ms Narwin and all the other staff for giving a bad name to the school and causing them so much trouble.
