The �Control� tab lets you control your spending and monitor energy use.
When initially visited, the chart at the centre of the �Control� page shows the most recent five weeks of electricity spending, with the current week highlighted in green.
The spending is separated into the Service
Charge (charged on a flat daily basis) and the Usage Charge
which is based on the amount of electricity consumed. The blue line which runs through the middle
of the chart reflects your weekly electricity budget.
