Will fossil fuels such as oil and gas still be the world’s main source of energy in the coming decades?

There have been a lot of discussion and debates about the world's main source of energy in the coming decades. I think that fossil fuels will still be the world's main source of energy in the coming decades for the following three reasons.
Firstly, fossil fuels can be used for the source of energy easily because energy suppliers have many energy generators based on them.

For,example. the rate of the energy generators based on the fossil fuels is over 50%. Many energy company have high technology to generate the energy.

For energy suppliers fossil fuels is useful because they are used to generate energy from them.

Secondly, we can get fossil fuel easier than before with low cost.

For,example the earth have a large amount of fossil fuels if we can dig the soil deeper. Recent technology afford us to do it easily.

The cost of fossil fuel is lower than before with recent technology.

Thirdly, there are many workers in the supply chain of fossil fuels.

For example . In fossil fuel market there are many category which are mining raw material, creating fuels, suppling the energy and so on. There are many workers in this markets.

People want to keep working in the fossil fuels market.

In conclusion,For above mentioned three reasons , I agree this theme.
