A power company burns coal to generate electricity. The cost C (x) (in $1000) to remove x% of the air pollutants is given by:

A coal-fired power station produces electricity worth $40 per unit to consumers. However, for each unit produced air pollution is produced, costing $20, which is not reflected in the price of electricity paid by consumers. Suppose a Pigovian tax has been implemented to correct the market distortion. In the Social CBA the production of additional electricity should be priced at:

14. How much of the energy in burning coal reaches the consumer as electricity?

From the power plant, it took 100 kJ of coal to produce the 15 kJ of useful energy in your home.  What is the total efficiency?

When any fossil fuel is burned it produces emissions of carbon dioxide and water vapor. A typical household in a developed country will use approximately 70 kWh per month of electricity for computing and electronics. Each kWh of average coal burned produces 2.23 kg of carbon dioxide emissions while natural gas produces just 0.91 kg per kWh of carbon dioxide.How many more kg of carbon dioxide are produced by the coal plant compared to the natural gas plant from the computing and electronics alone, from a household over the course of one year?

What is the efficiency of the coal based power systems? 5-6% 7-8% 8-10% 10-12%
