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 is given by MC(y) = 7y, where x is the amount of emissions reduction done by the first power plant, and y is the amount of emissions reduction done by the second power plant.

In order to ensure that the target level of emissions reduction is achieved in the most cost-effective way, what should x be? Please round your answer to 2 decimal places.

Solutions

Expert Solution

Where equation says ,

5x +7y = 180(tons)

Assuming x = 0,

5(0) + 7y = 180

0+ 7y= 180

y = 180/7

y= 25.71.

Now taking y = 0

5x + 7(0) = 180

5x + 0= 180

5x = 180

x = 180/5

x = 36

Therefore the amount of emission reduction done by the first powerplant (x) = 36.0( rounding upto 2 decimals)

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

3) You are interested in the effects of coal-fired power plants on local mercury contamination in wetlands. Your funding comes from a local power company that wants 2 of the plants to be their power plants in Illinois. You look at a map and select 2 of their plants and 2 plants that are of similar energy output. You want to know if the power plant is having an effect on mercury concentrations in sediment samples. In addition to what...

Coal-fired power plants are known to release a lot of pollutants such as sulphur dioxide, carbon monoxide, mercury, ashes, etc. (i) Does it matter to a coal-fired power plant whether there is a liability law or not? If so, explain in what ways. (ii) Is there is any incentive to innovate (i.e. adopt new abatement technology) under a liability law for a polluter? Explain.
