The chart below shows the expenditure on three categories among different age groups of residents in the UK in 2004. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The given process charts illustrate the pattern of the wave energy system and its region. To start with the instrument design, there are mainly 2 compartments and an electricity generator located on the left side of the tool. In the first step, the water is stored in the first compartment with the help of waves force. As the water level reaches 3/4th level, it passes the airflow to the turbine from air chambers. Next, the turbine runs with this airflow and throws the air outside the camber. On the other hand, outside air enters the upper turbine. In addition, this air goes to the inner chamber(water level). As both turbines run, they generate electricity, which stored in an electricity generator. In the second image, there are two locations suggested for machine installation. The first location is in the high level of water where, we get a high amount of electricity; on the contrary, it takes high investment. However, another option is totally the opposite of the earlier one. In conclusion, the tool's diagram is quite simple and easy to understand. It shows how the water-energy can convert into electric energy. Also, it suggests its location.
