Compare the yearly greenhouse gas emissions from 1 GWe (gigawatt-electric) power stations powered by natural gas and wind turbines. The energy content of natural gas is 55 MJ/kg, and the electrical converting efficiency is 40%. Wind turbines do not emit CO₂ as they harness the wind but emissions do occur during the manufacturing of the turbine. For USA, assume the CO₂ emission per GDP is approximately 500 Tonnes / $ 1 million of GDP. For wind turbines, it costs $2 million for a 1 MWe plant, which has an efficiency of 0.3, and the yearly maintenance is approximately 2% of the initial cost. Assume the average lifetime of a wind turbine is 20 years.

Calculate the emissions reduction if a natural gas power plant is converted to biogas. 81 % of the biogas emissions are absorbed by regrowing the source material. Fuel properties: • methane content of Natural gas: 72 % • calorific value of methane: 55 GJ/t • ethane content of Natural gas: 20 % • calorific value of ethane: 51 GJ/t • remainder of Natural gas is CO2 • methane content of biogas: 54 % • remainder of biogas is CO2 Calculate...

Carbon Emissions from Natural Gas: Worldwide combustion of methane, CH4 (natural gas), provides about 10.9 × 1016 kJ of energy per year. If methane has an energy content of 39 × 103 kJ/m3 (at STP: Standard Temperature and Pressure), what mass of CO2 is emitted into the atmosphere each year? Also express that emission rate as metric tons of carbon (not CO2) per year. A metric ton, which is 1,000 kg is usually written as tonne to distinguish it from...

The data found below measures the amounts of greenhouse gas emissions from randomly three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.05 significance level to test the claim that the different types of vehicles have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? Type A Type B Type C 5.6 8.7 9.6 6.9...

The Regional Greenhouse Gas Initiative (RGGI) is a cap and trade program for controlling emissions of CO2 from electricity generators. Allowances are freely tradable across the RGGI states and unused allowances are bankable to future years. The market for RGGI allowances is competitive. The allowance price is currently $6. Here is a chance to use your understanding of emission markets: a) Virginia will be under the RGGI cap next year. UVA has decided that next year it will pay to...

Write the ingredient list of your meal with the associated greenhouse gas emissions individually (for each ingredient). Then, add the greenhouse gas emissions of your total meal. In a few sentences discuss your meal. Are there ways you could reduce your greenhouse gas emission by substituting different products?

Mars Engineering Industries must choose between a gas-powered and an electric- powered generator for their factory. Both generators perform the same function. The electric-powered generator will cost $20,000 and the gas-powered generator will cost $16,500. The life of each type of generator is estimated to be 5 years during which time the net cash flow per year for gas-powered generator will be $5,000 and that for electric-powered generator will be $6,500. The cost of capital for Mars is 13%. Calculate...

Davis Industries must choose between a gas powered or an electric powered forklift truck for moving materials in its factory. The electric powered truck will cost more, but it will be less expensive to operate; it will cost $22,000 whereas the gas powered will cost $17,500. The cost of capital is 12%. The life of both trucks is expected to be six years. The net cash inflows for the electric powered truck will be $6,290 per year and those for...

1) A new car that is a gas- and electric-powered hybrid has recently hit the market. The distance travelled on 1 gallon of fuel is normally distributed with a mean of 55 miles and a standard deviation of 6 miles. Find the probability of the following events: A. The car travels more than 59 miles per gallon. Probability = B. The car travels less than 51 miles per gallon. Probability = C. The car travels between 50 and 63 miles...

Davis Industries must choose between a gas-powered and an electric-powered forklift truck for moving materials in its factory. Because both forklifts perform the same function, the firm will choose only one. (They are mutually exclusive investments.) The electric-powered truck will cost more, but it will be less expensive to operate; it will cost $21,000, whereas the gas-powered truck will cost $17,230. The cost of capital that applies to both investments is 11%. The life for both types of truck is...
