The secret energy source of a hurricane is the large latent heat of water. Air over the tropical oceans is drier than you might think. Although both the air and water may be warm and calm, evaporation can take place because the air is not at 100 percent relative humidity.
Whipping up a hurricane calls for a number of ingredients readily available in tropical areas:
A pre-existing weather disturbance: A hurricane often starts out as a tropical wave. Warm water: Water at least 26.5 degrees Celsius over a depth of 50 meters powers the storm. Thunderstorm activity: Thunderstorms turn ocean heat into hurricane fuel. Low wind shear: A large difference in wind speed and direction around or near the storm can weaken it.

Another popular query is “Where do hurricanes gain and lose energy?”.
Hurricanes, known generically as tropical cyclones, are low-pressure systems with organized thunderstorm activity that form over tropical or subtropical waters. They gain their energy from warm ocean waters. Satellite images of the disturbance that became Hurricane Maria in September 2017.

You could be asking “How does energy from the Sun Power Hurricanes?”
One answer is the energy required to make this change comes from the sun, and this energy is lying in wait — latent — ready to be released when the vapor is condensed into liquid again. This happens in rising air in a cloud or thunderstorm. However, this process alone is not enough to power a hurricane.
Do hurricanes gain energy as they near land?
Once a hurricane reaches cooler water or land, the energy source is gone and the hurricane will slowly diminish and release less energy. Powerful hurricanes hold an enormous potential as renewable energy sources, and one aspect of these storms is the renewable wind energy that can be harnessed.
Our answer is that hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. This humid air is then dragged aloft when converging winds collide and turn upwards. At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, causing it to rise as well.
Where do severe storms get their energy from?
Two key ingredients for severe storms are (1) energy driven by warm, moist air promoting strong updrafts, and (2) changing wind speed and direction, known as wind shear, which allows storms to become stronger and longer-lived.
