If the turbine were perfectly efficient, all of the potential energy of 19600 joules would be converted into mechanical energy. To convert this to power output in watts, you would divide the energy by the time taken for the conversion to occur. If the conversion happened in 10 seconds, the power output would be 1960 watts (19600 joules / 10 seconds).
An incandescent bulb is 96% efficient as a heater, and 4% efficient as a source of light. A fluorescent bulb is only 60% efficient as a heater, and 40% efficient as a source of light. An LED bulb is only 10-20% efficient as a heater, and 80-90% efficient as a source of light (but that light is usually unidirectionally directed... harder to do diffuse lighting with them).
Most modern fridges are designed to be energy-efficient, meeting strict energy efficiency standards. However, older fridges may not be as efficient, leading to higher energy consumption. It's important to look for the Energy Star label when purchasing a new fridge to ensure it is energy-efficient.
To calculate the mechanical energy provided by the motor, you need to divide the input energy by the efficiency of the motor. In this case, with 70% efficiency, you would divide 1960 joules by 0.70 to find that the mechanical energy provided would be approximately 2800 joules.
One of the most efficient things in the world is photosynthesis, the process by which plants convert sunlight into energy. It is highly efficient at converting solar energy into chemical energy that sustains life on Earth.
