That's because the energy sources themselves are different! For example, some energy sources (such as coal) produce pollution, because they rely on chemical reactions; others don't, either because they don't use chemical reactions (such as wind energy), or because the results of the chemical reactions are harmless (such as when you burn hydrogen - in which case the end result is water).
What are the advantages and disadvantages of wave energy
There are no energy sources without disadvantages.
There is no single "best" form of energy as different sources have their own advantages and disadvantages. It depends on factors like availability, cost, environmental impact, and efficiency. A mix of renewable sources such as solar, wind, and hydropower is generally considered ideal for a sustainable energy future.

Wave and tidal energy offer advantages such as being renewable, abundant, and predictable sources of power. However, they also have disadvantages like high initial costs, environmental impacts, and limited locations for effective utilization.

Advantages: Chemical energy is a widely available and portable source of energy used in various applications such as transportation and electricity generation. It is also relatively cost-effective compared to some alternative energy sources. Disadvantages: The combustion of chemical fuels can release pollutants and greenhouse gases, contributing to air pollution and climate change. There are also concerns about the finite nature of some chemical energy sources and their impact on the environment.
The non-conventional sources of energy are: 1. Wind Energy advantages- non-polluting; low cost production of electricity once setup; safe and clean disadvantages- noise pollution; wind mills costly to setup; disturbs radio and T.V. reception; harmful to birds. 2. Solar Energy advantages- inexhaustible; non-polluting disadvantages- expensive; diffused source, so gets wasted. 3. Tidal Energy advantages- non-polluting; inexhaustible disadvantages- destroys wildlife habitat; difficult to harness 4. Nuclear energy advantages- Emits large amount of energy disadvantages- generates radioactive waste; expensive 5. Bio Gas advantages- low cost; easy to operate; makes use of bio waste disadvantages- causes green house effect 6. Geothermal Energy advantages- clean Eco friendly and always available disadvantages- located far away from cities and so costly to transport the electricity
Advantages: Clearly shows the flow of energy through trophic levels, helps understand energy transfer efficiency, and provides a visual representation of ecosystem functioning. Disadvantages: Ignores energy lost as heat through respiration, does not account for different efficiencies of energy transfer between different ecosystems, and may oversimplify complex food webs.
