The data of installed capacity of electricity produced by different sources of energy (solar, wind and coal) in two states (X) and (Y) alongwith their respective populations are given for the years 2011 and 2021 in the table given below. Based on the data, answer the following questions: Statewise details of population and installed capacity of electricity Population (mn) Solar (GW) Wind (GW) Coal (GW) Population (mn) Solar (GW) Wind (GW) Coal (GW)State X State Y Year 2011 50 20 10 40 60 15 08 50 2021 60 28 15 42 68 20 10 55
Per capita availability of electricity was least in
The question asks us to determine in which state and year the per capita availability of electricity was the least. Per capita availability is calculated by dividing the total installed electricity capacity by the population.
First, let's look at the data provided in the table:
| State | Year | Population (mn) | Installed Capacity (GW) | Total Installed Capacity (GW) | ||
|---|---|---|---|---|---|---|
| Solar | Wind | Coal | ||||
| State X | 2011 | 50 | 2 | 0 | 10 | $2 + 0 + 10 = 12$ |
| 2021 | 60 | 28 | 15 | 42 | $28 + 15 + 42 = 85$ | |
| State Y | 2011 | 60 | 1 | 5 | 8 | $1 + 5 + 8 = 14$ |
| 2021 | 68 | 20 | 10 | 55 | $20 + 10 + 55 = 85$ | |
Now, we calculate the per capita availability of electricity for each state and year. The formula is:
$\text{Per Capita Availability} = \frac{\text{Total Installed Capacity (GW)}}{\text{Population (mn)}}$
Let's compare the calculated values:
Comparing these values, $0.2333 \text{ GW/mn}$ is the smallest value among the four. This value corresponds to State Y in the year 2011.
Based on the calculations, the per capita availability of electricity was least in State Y, year 2011.
| State | Year | Population (mn) | Total Capacity (GW) | Per Capita Availability (GW/mn) |
|---|---|---|---|---|
| State X | 2011 | 50 | 12 | 0.24 |
| State Y | 2011 | 60 | 14 | $\approx 0.2333$ |
| State X | 2021 | 60 | 85 | $\approx 1.4167$ |
| State Y | 2021 | 68 | 85 | $\approx 1.25$ |
Per capita installed electricity capacity is an important indicator of a region's ability to supply power to its population. It represents the amount of generating capacity available per person.
