Typhoons derive their energy from

Typhoons are tropical storms with wind speeds of at least 74 miles (119 kilometers) per hour just like a hurricane.
Typhoon derives their energy from Latent heat of vaporization of water from the ocean surface, which ultimately condenses into clouds and rain when moist air rises and cools to saturation. Thus the main source of energy for typhoons is the Ocean both by direct heat transfer from their surface and by the evaporation of water.
