Thermodynamic process The Sun supplies electromagnetic energy to Earth. It appears to have an effective temperature of approximately 5,800 K. On a clear summer day in North America, the incident energy on a surface facing the Sun is approximately 0.95 kW / m2. Electromagnetic solar energy can be converted into thermal energy by being absorbed by a darkened surface. How could you characterize the work potential of solar energy when it is to be used to produce work?
