The diagrams below show the design for a wave-energy machine and its location. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The picture represents how wave-energy machines work and where are located, describing that water movement and air flow can produce energy through a turbine and a electricity generator. Firstly, the machines can be installed near the shoreline as far from it, regarding different type of waves and, thus, different intencity in outputs. While the first has low cost installation, the second is more expensive on the placing operations. Afterwards, the machine is characterised by a rectangular shape, where in the low part waves enter and, through the level of the water, air flow coming from the high makes the turbine works. Due to this movement of air and water, turbine spins and activates electricity generator that turns on and creates energy. By the way, this kind of energy takes advantage of natural air and water flows, so it could be considerate as renowable. Moreover, the difference between location options can give more possibilities for every amount of budget available. Consequently, it could be a great chance by governments to improve and expand energy sources.
