Basically two reasons.1) Fossil fuels won't last forever - we will run out of these fuels pretty soon.
2) Fossil fuels produce contamination, including filling the atmosphere with greenhouse gases.
because fossil fuels are a finit resource and some day in the not to distant future we will run out of it.
Currently, billions of people worldwide rely on fossil fuels for transportation, electricity generation, heating, and industrial processes. Fossil fuels remain a dominant energy source despite efforts to transition to cleaner alternatives.
Transportation, electricity generation, heating, and cooking.
Burning coal to generate electricity releases the most carbon dioxide of the fossil fuels.
Burning of fossil fuels (coal, oil and natural gas) is used in industry, transport and the generation of electricity.
The most common fossil fuels burned to generate electricity are coal, natural gas, and oil. Coal is the most widely used fossil fuel for electricity generation, followed by natural gas and then oil. These fossil fuels are burned in power plants to produce steam which drives turbines to generate electricity.
Natural gas typically burns the hottest and is considered one of the most efficient fossil fuels for electricity generation. It produces more heat energy per unit of fuel compared to coal and oil, resulting in higher electricity generation efficiency.
fossil fuels used gor heating water to produce steam which further runs turbine to generate electricity
It is important to find new ways of generating electricity to reduce reliance on fossil fuels, lower emissions contributing to climate change, and promote sustainability. Diversifying the sources of electricity generation also increases energy security and can lead to more affordable and reliable energy systems.
Currently around 71%: About 49% of electricity is generated from coal, 21% from natural gas, and 1% from petroleum. Adding those together, you get about 71%.
The burning of fossil fuels in industry, transport and the generation of electricity.
Electricity generation from fossil fuels pollutes the air, which gives many people different diseases, as well as causing global warming.
