Here are two common forms of chemical energy. Definition Example Use How Converted for Use carbohydrates hydrocarbons Matter that Has energy stored in it in chemical form is called fuel. Average Conversion Efficiency Conversion Loss Forms of Energy Produced in the Conversion Processes fuel cell hydrocarbon, hydrogen, etc. Using references to learn about various fuels Using references to obtain information about energy conversion devices Major Understandings Fuel is energy stored in chemical form. Various devices are used to transform the energy in fuels into work.
Different devices have different efficiencies.
The energy that is wasted in a conversion is usually in the form of heat. The more complex the society the greater its energy use per individual by these motors, engines, pumps, heaters etc. Electricity, a commonly used form of energy, is produced by turbines and generators, which are conversion devices. These devices are powered by various sources of energy, such as fossil fuels, hydropower, wind, nuclear, etc. The electricity produced is eventually converted or changed into other end use forms of energy such as heat, light, mechanical energy, and others.
