How can thermal pollution be prevented?

Answer

Following are the means to reduce thermal pollution:

1. Theoretically, when efficiency of any heat engine is equal to 1.0 then it will convert 100% of heat energy to mechanical energy. So there will be no loss of heat to the environment. This is practically impossible. Rather, we should aim at maximizing the efficiency of heat engines (steam, IC, nuclear etc) so that heat loss is minimum.

2. Reduce mechanical friction in any rotating parts.

3. Avoid consuming energy more than necessity. Burn less coal, oil or gas.

4. Promote use of more nuclear energy because it will not generate Carbon di oxide.

5. One of the major cause of Global warming is increasing concentration of Carbon di oxide, leading to more green house effect. On the other hand, green plants have got the capacity to absorb Carbon di oxide. In the photo synthesis plants take water, sunlight and carbon di oxide to prpoduce their food. So, plant as many trees as possible. Massive plantation is the only solution for reducing global carbon di oxide level. Indirect effect of plantation is, It will reduce soil temperature, cause more rains, some of the carbon di oxide shall be dissolved in rain and shall go to the sea - which will ultimately form carbonate rocks and will help in the flora and fauna of the marine life.

5. If we can follow these, certainly we shall be successful in reducing thermal pollution and will be able to prevent the glaciers from melting and rising of sea levels.
Thermal can be prevented very easily. Most of the people who cause thermal pollution are big facctories which use the water then pour it back in the ocean. To prevent this all they have to do is just cool the water before they put it back in the ocean.
