Solar energy comes from the sun. It drives the weather and feeds plants on Earth. In more specialized terms, solar energy refers to the technology that allows people to convert and use the energy of the sun for human activities. Part of the sun’s energy is thermal, meaning it is present in the form of heat. Some approaches to solar power convert the sun’s energy to heat, but for other approaches heat does not help at all. There are also other definitions of thermal energy that have nothing at all to do with the sun.
THERMAL ENERGY
The word "thermal" derives from the Greek word for heat, so thermal energy is technically heat. When engineers talk about thermal energy it is usually a bad thing -- waste. For example, an incandescent light bulb puts out light, but it actually puts out more heat than light. When your laptop computer warms your lap, that does nothing to help you do calculations -- it is wasted energy. This wasted energy is almost everywhere -- car engines, cellphones, televisions. This form of thermal energy has nothing to do with the sun.
