Question 2 secondary energy is energy in its natural and technically unconverted form true false

False

Explanation:

Primary energy is called the energy available in nature, in various forms, which can be used by humans to carry out activities, transform, store and transport it. Some sources can be used directly, such as the wind that drives a boat; others, after a process of extraction and transformation, as with the oil from which the fuel used by cars is extracted.

Primary energy sources are distinguished by natural resources such as wind, radiation from the Sun, moving water, coal, uranium, natural gas, oil, firewood, bagasse and other plant residues.

Secondary energy sources, on the other hand, are the result of transformations of primary energy sources and are not present in nature as resources, but are generated from them. Among the secondary sources, electricity and petroleum products are distinguished (naphtha, diesel, fuel oil, etc.). Today's societies are characterized by a high consumption of secondary energy sources produced in power generation plants and oil refineries.

A secondary energy source that does not yet have a significant volume of use is hydrogen H2. Hydrogen is not found in the free state in nature, but is combined with other elements, such as in water (H2O) or natural gas (CH4), and it is necessary to use energy to isolate it
