Perspectives/Comparison Basis Hydroelectric plants Coal Fired Plants
Economical Perspective

**Difference: It's erection cost is very high as it needs large area of land

**Similarity: Produced power cost is almost same

**Difference: Erectection cost is low with respect to Hydroelectric plants

**Similarity: Produced power cost is almost same

Social Perspective

**Similarity:Generates employment

**Difference: It causes displacement of people living on land on which Hydroelectric plant and Reservoir was made

**Similarity:Generates employment

**Difference:It do causes people displacement as needs smaller land or area than Hydroelectric plants

Environmental Perspective

**Similarity:It causes cutting of trees and so degrades environment

**Difference: Do not cause air pollution at any stage of operation

**Similarity:It also cause cutting of trees so disturbing nearby environment and animals.

**Difference: Cause air pollution if not properly operated

Consider the environmental damage that results from the emissions of coal-fired power plants. These plants produce pollutants such as sulfur dioxide (SO2) and nitrogen oxide (NOx), which combine with hydrogen to make acid rain. They release mercury into the environment and emit other particulate matter such as soot, as well. Which of these externalities are highly localized, and which are borne by society at large? Explain

There are two coal-fired power plants located in the vicinity of a major metropolitan area. These power plants emit sulphur dioxide, which causes respiratory issues for the metro population as well as resulting in acidic rainfall.  The EPA has determined that the amount of sulphur dioxide emitted needs to be reduced by 180 tons. The marginal abatement cost function for the first power plant is given by MC(x) = 5x and the marginal abatement cost function for the second power plant...

There are two coal-fired power plants located in the vicinity of a major metropolitan area. These power plants emit sulphur dioxide, which causes respiratory issues for the metro population as well as resulting in acidic rainfall. The EPA has determined that the amount of sulphur dioxide emitted needs to be reduced by 169 tons. The marginal abatement cost function for the first power plant is given by MC(x) = 4x and the marginal abatement cost function for the second power...
