Energy Resources and Their Challenges

Fossil fuels and biomass both release carbon dioxide (CO2) when burned, contributing to greenhouse gas emissions and climate change.

Uranium-235 is a highly radioactive element used in nuclear power plants. It produces a vast amount of energy compared to coal due to nuclear fission.

Fractional distillation is a process used to separate different components of petroleum based on their boiling points. This allows for the production of various fuels like diesel, octane, and other useful products.

Hydrogen fuel cells produce only water as a byproduct when used for energy, making them a clean and sustainable option. However, challenges include high production costs and energy requirements for hydrogen generation.

Nuclear fuel, like uranium, generates energy through nuclear fission, which produces zero greenhouse gas emissions. However, its major disadvantage is the production of radioactive waste, which requires safe storage and management.

Movement of water due to gravitational forces between Earth, Moon, and Sun.

Splitting of an atom's nucleus, releasing energy.

Combining of atomic nuclei, releasing energy.

A radioactive element commonly used as fuel in nuclear reactors.

The process of turning mechanical energy into electrical energy.

The amount of a substance that remains after a half-life has passed.

Control rods absorb neutrons to moderate the nuclear reaction rate.

When a species reaches the maximum population it can sustain due to resource limitations.

Pollutants react with sunlight to form smog.

The process of converting sunlight directly into electricity.
