Air Pollution Facts

by Air Pollution Facts
(US)

Air pollution threatens the health of human beings and other living things on our planet. While often invisible, pollutants in the air create smog and acid rain, cause cancer or other serious health effects, diminish the protective ozone layer in the upper atmosphere, and contribute to the potential for world climate change.

3 Facts About Clean Coal

Hailed as one of the possible solutions to the fossil fuel emission problem, clean coal is coal whose sulfur dioxide is removed and whose carbon dioxide can be recovered easily. It’s still a subject for debate, though, since the technology is theoretical. Here are a few facts about this new type of energy.

1. Not all coal impurities can be removed. Clean coal is essentially an oxymoron! We can’t remove all the impurities from coal, and capturing the ones that remain is still not available on a wide scale. It still gives more emissions than wind or solar power.

2. It is expensive. This may change in the future, but right now the manufacture and burning of clean coal costs quite a bit of money, making renewable energy sources more cost-effective.

3. It may not even happen. There are too many faults with the technology right now, and incorrect implementation will damage our environment because of the possible leaks and emissions it can cause!

I’m all for alternate energy sources, but for me, clean coal is a bad choice due to better alternatives already available, like wind, solar and hydroelectric. What do you think about clean coal? Is it viable?
