Answer: Hydro-electricity
Explanation: After all it is technology right. The population can use the waves even the tides of the ocean's water to create electricity which is reliable. of course in the beginning it will be expensive but the result will be effective useful. The area having a dry climate could be because of the winds that blow precipitating clouds away but they can have a stable climate by planting more trees where rain can be processed within the geographical location. Finally, the problem of water supply can be fixed by installing water pipes to transport water to the community but in the process, water can be filtered or cleansed to prevent some diseases and social issues/calamities.
all credit to geography
