Answer:

<u>Fossil energy has been a fundamental driver of the technological, social, economic and development progress which has followed.</u><u>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.</u><u>Fossil energy has been a fundamental driver of the technological, social, economic and development progress which has followed.</u><u>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</u><u>.</u><u>There would be more research on the use of alternate fuels.</u><u>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.</u><u>Solar energy can only be captured during daylight hours.</u>

What is the sequence of energy transformations that occur in a nuclear reactor?
GuDViN [60]

Answer:

option (B) is correct

Explanation:

In case of nuclear reactors first the nuclear energy is emitted due to the nuclear fission of heavy elements.

This nuclear energy is emitted in the form of heat energy.

This heat energy is used to rotate the turbines, that means it is converted in the form of mechanical energy and then finally this mechanical energy is converted into electrical energy.
