The image contains two separate data visualizations. The first is a graph titled "Typical daily demand for electricity" displaying units of electricity on the y-axis, from 0 to 50000 in increments of 10000, and different hours of a day on the x-axis from 0 to 24. It depicts two lines representing winter and summer electricity demand, with winter starting at about 40000 units at 0 hrs, dropping to just above 20000 units at 3 hrs, rising to approximately 45000 units at 9 hrs and slowly declining to 30000 units by 24 hrs; meanwhile, summer starts at just above 20000 units at 0 hrs, dips slightly below until 6 hrs, gradually increases to nearly 30000 units at 15 hrs and drops back to around 20000 units by 24 hrs. The second visualization is a pie chart titled "What the electricity is used for" indicating percentages for different uses: Heating rooms, Heating water 52.5%, Ovens, Kettle, Washing Machines 17.5%, Lighting, TV, Radio 15%, and Vacuum cleaners, food mixers, Electric tools 15%.

The pie chart illustrates the typical demand for electricity in winter and summer, whereas the chart compares the items electricity used for.
Overall, it is clear from the line graph that electricity demand is substantially higher in winter than in summer throughout the day. When it comes to the bar chart, heating rooms and water accounts for over a half of the overall energy consumed.
Looking first at the line graph, demand for electricity was around 35000 units at midnight before rising to 40000 units at 3 a.m. However, this value declines dramatically around 8 a.m, at 30000 units. Thereafter, demand increases gradually to 40000 units from 12 p.m to 18 p.m. Following this, the figure reaches an all-time high of roughly 50000 units of electricity before falling sharply to its earlier level, at around 35000 units.
Turning to the pie chart, the percentage of the usage of electricity for heating purposes accounts for just over half of the overall energy consumption, at 52.5%. Ovens, kettle, and washing machine, however, make up just 17.5%, whereas lighting, TV, and radio, together with vacuum cleaners, food mixers and other electric tools, each represent 15% of an overall electricity usage.
