Question 2. A household with electric resistance heating plans to switch from resistive heating to a ground source heat pump. Annual heat consumption of the house is 30 000 kWh. Investment cost of the heat pump is 21 000 €. Heat pumps COP is 4.0. How much are the annual savings compared to resistive heating after the change of the heating system (in kWh)? Average price of electricity is assumed to be 12 c/kWh. Round off your answer to one decimal digit and enter it without the unit.
Example 1.3 160 MW. Its annual load factor is 0.6. The coal consumption is 1 kg per kWh of energy A thermal power plant of 210 MW capacity has the maximum load of generated and the cost of coal is Rs 450.00 per tonne. Calculate (a) the annual revenue earned if energy is sold at Re 1 per kWh and (b) the capacity factor of the plant.

A 1000 MW coal fired power plant (30% efficiency). The coal is 75% carbon and has a heat content of 10, 000 BTU/lb. What is the carbon emission (ton carbon per year)?
2) The energy consumed by a shower for 30 days is 22kwh. It is known that the resistance of the showerhead is 20 ohms and that its nominal current is 15A. So, what is the time in minutes that the shower was turned on during this period?
This is Problem 13 of Chapter 3 in Sustainable Energy by Richard Dunlap, 2nd Edition. I need help solving it: A coal-fired generating station has an efficiency of 38% and produces an average electrical output of 1000 MWe.(a) How much coal does it burn per second (kg/s)? Assume the coal is bituminous.(b) How much heat (in joules) is released to the environment per second?(c) How many liters of water at 20°C could the heat in part (b) boil (at STP) per second? For c, here is my idea: use Q = mc(change in T). Here change in T is (100 C - 20 C) or 80 C and c = 4200 J/(kg C) so I can solve for m. Question: I need the density of water to find liters, but density changes with temperature. So, do I use the regular 1000 kg/m^3 or something else?
. a. A group of engineering students designs an electric heater with a power rating of 15 kW. If 10 kg of ice at 200 K is placed in the heater, how many minutes will it take to change ice to steam at 400 K. Assume 100% efficient.
) Two boilers, one with superheater(B1) and other without superheater(B2) are delivering equal quantities of steam into a common main. The pressure in the boiler and main is 20 bars. The temperature of the steam from a boiler with a superheater is 350oC and temperature of the steam in the main is 250oC. The steam in B2 is wet steam at 20oC. i) Draw a sketch of the problem with all thermodynamic properties from steam table shown on the sketch. ii) Determine the quantity of steam supplied by the other boiler.

In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
