Question 2 Portugal has a typical insolation of 1000 W/m2. A solar PV plant located there has an output of 11 MWp. Since the collectors track the sun, the power output is steady at 11 MW from 09:00 to 16:00 Hrs and almost zero outside this time. The lifetime of the system is 20 years with an annual operating cost and total capital investment of €1 million and €75 million, respectively. The cost of capital is 7% p.a. The efficiency...

Problem 2. The average per capita rate of primary energy use in Canada is approximately 13 kW. Spruce trees grow at an average rate of approximately 0.005 kg/m2 of forest per day and have an average energy content of 1.7 x 107 J/kg. (a) If all energy in Canada were generated from spruce trees with the same average efficiency as present energy sources, what is the area of spruce forest needed to satisfy one person's energy needs? (b) What is...

A scientist designed a gas turbine based-ocean thermal energy conversion (OTEC) system. Is it a wise idea to do so, if not why, suggest an alternative way? Calculate the Carnot (ideal) efficiency of a common OTEC system.
7.26. The conversion of the kinetic energy of wind to electricity may be an attractive altemative to the use of fossil fuels. Typically, wind causes the rotor of a turbine to turn, and a generator converts the rotational kinetic energy ofthe rotor into electricity. Power generated by a wind turbine (Ws) can be estimated from the density of the air (p), wind speed (u), and turbine rotor diameter (D) using the following formula лD? 1 W. ти* х п, where...
4. What is the yield to maturity (YTM) of a 20-yr. bond w/ a coupon rate of 10%/yr., has a $1K par value, and is currently priced at $1196.36? Round your answer to the nearest whole percent. Coupons are paid annually. Calculate the YTM if the price is $850.61. Finally, calculate YTM if the price is $1000.00.
