Figure 13 shows a large wind farm off the coast of the UK - AQA - GCSE Physics - Question 9 - 2022 - Paper 1

To find the mean power needed for one home, we can use the total power output of the wind farm and divide it by the number of homes it can power.

Given that the wind farm produces 696 megawatts (MW) and powers 580,000 homes, we first convert megawatts to watts:

$696 ext{ MW} = 696 imes 10^6 ext{ W} = 696000000 ext{ W}$

Next, we divide this total power by the number of homes:

$ext{Mean Power per Home} = \frac{696000000 ext{ W}}{580000 ext{ homes}}$

Calculating this gives:

$\text{Mean Power per Home} = 1200 ext{ W}$

Thus, the mean power needed for 1 home is 1200 W.
