A secondary source has the benefit of hindsight.
The two different sources are primary and secondary sources
That means that there is a primary source of energy, and the secondary one is used incase the other fails.
Secondary energy is converted from primary energy sources. Electricity is the most common example of a secondary energy source. Electricity is converted from coal, gas, nuclear plants, windmills, solar panels and even running water.
Secondary energy sources are also referred to as energy carriers, because they move energy in a useable form from one place to another. There are two well-known energy carriers:ElectricityHydrogenPeople make electricity and hydrogen from the conversion of other sources of energy, such as coal, nuclear, or solar energy. These are called primary sources.For many energy needs, it is much easier to use electricity or hydrogen than it is to use the primary energy sources themselves.
Electricity is a secondary power source. It depends on what is used to generate it. Wind, water or solar are all renewable or use little or nothing after the original manufacture of the component's.
Primary source information is original material,Secondary sources analyze and interpret primary sources
The thing that helps you to distinguish the primary and secondary source is that in the primary one you have actually proof in hand about it such as a book that the person wrote or their video. Secondary is a document that man analyzed and summed up.
Primary sources are original materials that provide first-hand accounts of events or research findings, like diaries or scientific studies. Secondary sources analyze, interpret, or summarize primary sources, such as textbooks or literature reviews. Primary sources offer direct evidence, while secondary sources offer commentary or analysis on that evidence.
Primary topics are often secondary sources. Secondary sources analyze in review or summarize information.
Primary sources, secondary sources, and oral history.
secondary
They summarize conclusions about primary sources.
Primary sources and secondary sources
Primary sources of information are great because they are first hand information from someone who was there. Secondary sources are based on primary sources, and may be biased.
Types of sources of information include primary, secondary, and tertiary. Primary sources are from the original source. Secondary are a commentary using primary sources. Tertiary sources are largely expert opinion.
A secondary source is one that pulls from primary sources. Primary sources are direct reporting or accounts of historical events from those who witnessed them, and secondary sources analyze and summarize those.
