Commercial sources of energy are those that are produced and sold in the market, such as fossil fuels (coal, oil, natural gas), nuclear power, and electricity generated from renewable sources like wind and solar. These sources are typically regulated and traded, providing a reliable supply for industries and households. Non-commercial sources of energy, on the other hand, include traditional forms like biomass (wood, animal dung) and solar energy used directly for heating or cooking, which are often utilized at a local or household level without a formal market structure. They tend to be more renewable and sustainable but may lack the efficiency and consistency of commercial energy sources.
Energy from the burning of fossil fuels (coal, oil and natural gas) is non-renewable.
This is difficult to decide I think. It has been available for 50 years now - does that make it conventional? It is a well established and reliable energy source.
Solar energy is harnessed because it is a renewable source of energy and we should make full use of it to lower the pressure on the traditional or non-renewable sources of energy.

non renewable energy
Any energy source that has a fixed price tag in market are commercial sources of energy like petrol, diesel. But non-commercial energy sources don't have a fixed price in market, the cost is local and varies e.g. firewood
no its a renewable source of energy
renewable source of energy can be regenerated but non-renewable source of energy can not be regenerated.
Non-renewable energy source means that the source will eventually run out and is not renewable.
wind
Wind energy is a renewable resource, as there will always be wind.
No, wind is a renewable energy source. The wind will always be blowing!
non conventional energy = renewable energy http://en.wikipedia.org/wiki/Renewable_energy
the bio gas that the algae produce is the energy source.
You don't. There is no difference in the type of energy, between the "conventional" and "non-conventional" types. What makes energy conventional or non-conventional is the SOURCE - a conventional source being one that has been used for a long time.

Coal is the most widely used source of non-renewable energy.
