Depending on what kind of energy you are talking about... For millions, nay billions, of years, our ancestors ate food, so the energy source would be anything from which we got food. If you mean other than food, like technological uses, that would probably be wood, used to make a fire.
What else can I help you with?
What energy source has not been harnessed by man for peaceful purposes?
Nuclear fusion is an energy source that has not been successfully harnessed by man for peaceful purposes on a large scale. It holds great potential as a clean and abundant source of energy but is still in the experimental stage for commercial applications.
Is Hydrogen a renewable or nonrenewable energy source?
Hydrogen is a nonrenewable source of energy when used for nuclear fusion (which is still not a technologically attainable power generation mechanism). When used as an energy carrier for oxidation (e.g. fuel cell, and internal combustion engine) hydrogen is not an energy source. In such applications, hydrogen is a man-made resource.
What was on of the earliest forms of energy for heating?
One of the earliest forms of energy for heating was firewood. People would burn wood in open fires or hearths to generate heat for warmth and cooking. This practice dates back thousands of years and was a crucial source of energy before the advent of modern heating systems.
When a man climbing a hill what type of energy exists?
When a man climbs a hill, the energy involved is primarily mechanical energy from the muscles used to propel himself upward against gravity. This kinetic energy is converted from the body's chemical energy stored in food through the metabolic process.
What is the most powerful man made energy source on earth?
Nuclear energy is considered one of the most powerful man-made energy sources on Earth due to its high energy density and ability to generate large amounts of electricity. It is produced through nuclear reactions, such as fission or fusion, which release immense amounts of energy.
Who was the first to find energy?
Man has used fire (a source of energy) since ancient times and also used animals (a source of mechanical energy) to plough fields since ancient times. Therefore we do not know who was first to find energy.
What are the man energy sources?
The main energy source is the sun
What nutrients and compounds can the aerobic system use to resynthesise energy?
Glucose is the energy source that is used to release ATP through aerobic respiration. this is safe man
What is the man source of energy for the body?
ATP, adenosine triphosphate :)
What energy source has not been harnessed by man for peaceful purposes?
Nuclear fusion is an energy source that has not been successfully harnessed by man for peaceful purposes on a large scale. It holds great potential as a clean and abundant source of energy but is still in the experimental stage for commercial applications.
What molecule is the primary source of energy in living things?
The primary source of energy in living things is adenosine triphosphate (ATP). ATP is a molecule found in cells that stores and transfers energy for various cellular processes. It is produced during cellular respiration and used as an immediate source of energy for metabolic reactions.
Is polonium used in ironman?
Yes, polonium is used as a power source in Tony Stark's arc reactor in the Iron Man movies. It is shown to provide the energy needed to power the Iron Man suit.
Is Hydrogen a renewable or nonrenewable energy source?
Hydrogen is a nonrenewable source of energy when used for nuclear fusion (which is still not a technologically attainable power generation mechanism). When used as an energy carrier for oxidation (e.g. fuel cell, and internal combustion engine) hydrogen is not an energy source. In such applications, hydrogen is a man-made resource.
When was the source of the sun energy discovered?
It wasn't discovered, but seen by early man. How it was there was answered in myths and mythology by man.
When was obsidian invented?
It was not invented. It is a natural mineral and has been used by man since the earliest time.
How do you use the word oil in a sentence?
Olive oil is man's best source of energy.
Where was the earliest evidence of modern man discovered?
The earliest bones have been found in Africa. Man began in Africa.
