What is the most result of this increased use of foss?

Fossil energy has been a fundamental driver of the technological, social, economic and development progress which has followed.In 2019, around 84% of global primary energy came from coal, oil and gas. Over the coming decades we need to rapidly reduce this share by displacing them with low-carbon energy sources.Fossil energy has been a fundamental driver of the technological, social, economic and development progress which has followed.In the sections above we looked at the consumption of fossil fuels collectively. But it’s important to look at the role of coal, oil and gas individually – their impacts are not equal. Coal, for example, typically produces more CO2 and local air pollution per unit of energy.There would be more research on the use of alternate fuels.Moreover, fossil fuels are composed primarily of carbon and hydrogen atoms. On combustion they produce carbon dioxide, sulfur dioxide, and carbon monoxide as the main by-products.Solar energy can only be captured during daylight hours.

Explanation:

if you write this then you will get full marks in your assignment it is valied for up to 16 class I don't know about any further it I have mixed many iconic and logic facts that are imp in science!

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
