Electricity is not considered a primary energy source; it is a secondary energy source that is produced from primary sources such as coal, natural gas, nuclear, and renewable energy sources like wind and solar power. Primary energy sources are those that occur naturally in the environment, while secondary sources are produced from primary sources through a conversion process.
Electricity is not considered a primary energy source because it is a secondary energy carrier—it is produced from primary energy sources such as coal, natural gas, nuclear energy, or renewable sources. Primary sources are those that can be found naturally and are transformed into other forms of energy for our use.
The primary source of energy for trees is sunlight. Through the process of photosynthesis, trees convert sunlight into chemical energy in the form of sugars, which they use for growth and development.
The primary source of energy for living organisms is the sun. Through the process of photosynthesis, plants and other photosynthetic organisms convert sunlight into chemical energy stored in the form of glucose, which is used by all living things as a source of fuel for cellular processes.
The fundamental source of energy on Earth is the sun. Solar energy is the primary driver of most natural processes and life on our planet.
Carbohydrates are the body's primary and immediate source of energy.
The term clean source of energy refers to only primary energy sources as wind or solar energy. Electricity, by definition, is not a primary energy source. It is a secondary energy source that is could be produced by a clean energy source as wind or any renewable primary energy source or produced by fossil energy source as oil, natural gas, or coal.
Carbohydrates are the primary energy source for herbivores (cows, horses, etc.). Proteins are the primary energy source for carnivores (dogs, cats, etc.).
Carbohydrates are the body's primary and immediate source of energy.
The primary is the sun
The sun is the initial (primary) energy source for life. Ingestion and digestion of a food source is an animal's primary source of energy.

Wood is the first discovered primary energy source. Some believe that Solar energy (as heat caused by sun light) is the first discovered primary energy source.
the primary source of energy is sun.
Sunlight is Earth's primary source of energy.
Geothermal energy is considered a primary energy source because it comes directly from the Earth's heat stored in rocks and fluids beneath the Earth's surface. It is renewable and sustainable.
