Energy Sources and Nuclear Power

Nuclear fission vs. nuclear fusion

• Nuclear fission is the process of combining two light atoms to form a heavier atom.

• Nuclear fusion is the process of splitting a heavy atom into smaller atoms.

• Nuclear fission is the process of splitting a heavy atom into smaller atoms, releasing energy.

• Nuclear fusion occurs only in nuclear reactors.

Disadvantages of solar energy

• Solar energy is intermittent and requires large areas for panels.

• Solar energy is the most cost-effective energy source available.

• Solar energy can be generated at night without any issues.

• Solar energy systems require no maintenance after installation.

Naturally occurring element used in nuclear fission

• Uranium

• Plutonium

• Thorium

• Radium

Challenges of transitioning to an all-renewable energy plan

• High upfront costs and geographic limitations

• Unlimited availability of solar and wind resources

• No need for energy storage solutions

• Environmental benefits of large-scale installations

How tidal energy is harnessed

• By capturing the kinetic and potential energy from the natural rise and fall of ocean tides using turbines or barrages.

• By converting solar energy into electrical energy through photovoltaic cells.

• By using wind turbines to generate electricity from ocean winds.

• By building dams to store water and release it for energy generation.

Kind of rock associated with coal, petroleum, and natural gas

• Igneous rocks

• Metamorphic rocks

• Sedimentary rocks

• Volcanic rocks

Electricity generation from running water

• Electricity is generated from running water by using the kinetic energy of flowing water to turn a turbine, which then spins a generator to produce electricity.

• Electricity is generated from running water by using solar panels placed near rivers.

• Electricity is generated from running water by burning fossil fuels to heat water.

• Electricity is generated from running water by using wind turbines placed on the water surface.

Formation of coal, petroleum, and natural gas

• Coal primarily forms from decomposed plant matter in swampy environments.

• Petroleum is formed from the remains of dinosaurs buried under the earth.

• Natural gas is created from the combustion of fossil fuels.

• Coal, petroleum, and natural gas all originate from volcanic activity.

Ways to conserve energy at home

• Switch to energy-efficient appliances

• Use incandescent light bulbs

• Install a traditional thermostat

• Wash clothes in hot water

Advantages of using wind energy

• Wind energy is renewable and produces no greenhouse gas emissions during operation.

• Wind energy is the most expensive form of energy available today.

• Wind energy requires large amounts of water for operation.

• Wind energy is only effective in coastal areas.
