Question 6 Compare the carbon emissions per MJ to heat household water using the following two energy systems: a) A 25% efficient coal-fired power plant delivering electricity to a 99% efficient electric water heater. Assume LHV carbon intensity of coal is 25.8 gC/MJ. b) A new 50% efficient natural gas-fired combined cycle power plant to a 99% efficient electric water heater. You must calculate the LHV carbon intensity of natural gas. Assume 100% methane and ideal conditions. Assume 5% losses in electrical transmission lines and 90 MJ of fuel input to each system.

A small company is considering an investment of $2000 that can save 3000 kWh of electricity per year at $0.15/kWh while the annual maintenance fee is $50. The project has a lifetime of 8 years and the salvage value is 10% of the initial investment. -:) What is the simple payback period (SPP) (in years)? Blank 1 (Your choices: 4.0, 4.2, 4.6, 5.0, 5.2) -:) With an annual discount rate is 12%, what is the discounted payback period (in years)? 6.5 (Your choices: 5.9, 6.5, 7.6, 8.1, 8.9) -:) With an annual discount rate is 12%, what is the benefit-cost ratio (BCR)? (Hint: Benefit = Annual saving – Maintenance; Cost = Initial investment - Salvage) Blank 3 (Your choices: 0.92, 1.04, 1.12, 1.25, 1.43) Blank 1 Blank 2 Blank 3 Add your answer Add your answer Add your answer
