Answer:
What is a power grid?
C) Transmission lines and transformers that take and send electricity from generating facilities to end users
Explanation:
A power grid is a system of interconnected transmission lines and transformers that takes electricity from the producers to the consumers. The power grid is very important in the supply of electricity to consumers. Before power is to be transmitted to the consumers, it has to be generated. Traditionally, the conventional way of generating power was from central power stations that utilized sources like; fossil fuels, coal and natural gas. In the recent past, however, more advancements have been made towards more clean energy sources like; wind, geothermal and hydroelectricity. Clean energy sources have several benefits over the traditional sources of energy, like; they don't cause harm to the environment and also they are renewable since they can be used over and over without depletion.
Once the energy has been harnessed and converted to electricity, it needs to be transmitted. The network for transmission to the consumers is what makes up the power grid. Transmission is usually done at very high voltage to minimize losses. However, before providing it the consumers, the electricity needs to be converted to a low voltage by the use of transformers for domestic and commercial consumption.
Answer:
Cumulative net present value of the project is:
= $33.5 million.
The discounted cash flow rate of return is:
= 26%
Explanation:
a) Data and Calculations:
The capital cost of the combined heat and power system = $23 million
Expected net savings per year = $10 million
Project period = 10 years
Discount rate = 12%
Annuity PV factor for 10 years at 12% = 5.650
Total PV of the cash flows = $56.5 million (5.650 * $10 million)
NPV of the project = $33.5 million
Annualized NPV = $33.5 million/5.650
= $5,929,204
Discounted cash flow rate of return = Annualized NPV/Investment * 100
= $5,929,204/$23,000,000 * 100 = 26%
Answer:
The correct answer is letter "A": both the value of a good to society and the cost to society of making the good.
Explanation:
Price is the monetary value of a good or service that consumers are willing to pay and producers are willing to accept. <em>For companies, it represents the production costs of the good plus the unitary revenue they expect to obtain. For consumers, it is the value they provide to the good offered according to the type of need the good is destined to fulfill.</em>
