The cost comparison between natural gas and electric energy sources varies depending on factors like location, energy efficiency, and market prices. Generally, natural gas tends to be cheaper than electricity for heating and cooking, but electricity can be more cost-effective for certain appliances and uses. It's important to consider your specific energy needs and local rates to determine the most cost-efficient option.

The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
The main sources are hydro-electric, natural gas and oil.
Two categories of heat sources are natural heat sources and artificial heat sources. Natural heat sources include the sun, geothermal energy, and volcanic activity. Artificial heat sources include electric heaters, gas heaters, and oil heaters.
Natural sources of light include the sun and stars, while artificial sources of light include light bulbs and LED lights.
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
Natural light sources, like the sun, produce light through natural processes, while artificial light sources, like light bulbs, are man-made and produce light through electricity.
The comparison of joules between two energy sources affects their efficiency and effectiveness. Energy sources with higher joules are more efficient and effective in producing energy compared to those with lower joules. This is because higher joules mean more energy can be generated from the source, leading to better performance and productivity.
Heat can be generated using both gas and electric sources. Gas heat is produced by burning natural gas or propane, while electric heat is generated by passing electricity through a heating element.
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
they are all energy sources
Examples of heat sources could be grouped into two (2) based on there origin. They are; 1. Natural Heat Sources. The natural heat sources could be sub-divided into two; a. External Source, e.g Sun. b. Internal Source, e.g Geothermal, i.e. Magma. 2. Man-made Heat Sources. These includes heat generated from; a. Electricity, e.g Electric Cooker and Oven. b. Fire, e.g Coal.
