energy

What are some steps that might be taken in the next 10 to 30 years to improve the sus- tainability of energy use?

The coal combustion in the furnace of steam power plant produces p=44.03 mega-Watts (MW) of heating power to produce steam. 0.1*p mega-Watts are lost from the factory infrastructure (pipes, vanes, etc). The depleted steam is cooled by a water cooling system that expels 0.45*p of waste heat to the environment. Calculate the net mechanical power output. Present your answer in mega-Watts (MW).

A Carnot heat pump is to be used to heat a house and maintain it at 25°C in winter. On a day when the average outdoor temperature remains at about 2°C, the house is estimated to lose heat at a rate of 55,000 kJ/h. The heat pump consumes 4.8 kW of power while operating. 55,000 kJ/h Determine the total heating costs, assuming an average price of $0.11/kWh for electricity. The total heating cost is $40.33 (You must provide an answer before moving to the next part.)
