How much we reduce carbon over the next five years is dependent on the weather – very dry weather means we will need to pump more water, and very cloudy weather means we will generate less electricity from solar panels.
The variability comes from the weather which can significantly affect our energy consumption.
In the graph, the red line shows how our emissions will fall without investment as a result of the change in emission factors.With investment our emissions will be within the shaded area. The variability comes from the weather which can significantly affect our energy consumption.
