The graph shows the electrical energy consumption of a typical household over the period of 24 hours, starting at midnight. Rank the usage of electric power at the specified times.
The graph shows the electrical energy consumption of a typical household.... How do you work this?
A solar power-plant can supply 1 million homes. The average energy consumption of a typical home is around 10,800 kWh per year. What is the capacity of this power plant in MW? Assume the capacity factor to be 0.44 for calculations.
