• Depending on the site, you sometimes get a bunch of energy at one time, or hardly any energy at other times

  • The waves would constantly have to be strong

  • The construction of the machine would have to be very durable and able to withstand rough waters
  • Costly to develop
  • Can disturb or disrupt marine life


Other than the challenge of the durability of the machine in the waters ,the cost of building the generators is still a problem because a lot of research is still needed to be done, and the energy source can be unpredictable because not all waves are the same.
