Renewable and Non Renewable Energy

Renewable resource

A resource that can be replaced at a sustainable rate.

Non renewable resource

A resource that cannot be replaced at the rate they are consumed

Advantages of using Fossil Fuels

Cheap compared to other energy sources. Buildings are already designed to use fossil fuels Easy to transport and store Not Weather Dependent

What type of energy is Fossil Fuels?

Chemical

What type of energy is Hydrogen Fuel Cells?

Chemical

Energy Transformation diagram of Fossil Fuels

Chemical --> Heat --> Motion -->Electrical

List the Fossil Fuels

Coal, Oil, Natural Gas

List the Nonrenewable Fuels

Coal, Oil, Natural Gas, and Nuclear Power

Advantages of Solar Power

Does not produce CO2 Low maintenance Minimal ecosystem disruption Can be placed in sparsely populated areas or on top of buildings

Advantages of Hydrogen Fuel Cells

Does not produce CO2 Not weather dependent Water is the only waste product

Where does Natural Gas come from?

Drilled for underground, in areas that were previously underwater, it is the dead matter of marine organisms

Where does Oil come from?

Drilled for underground, in areas that were previously underwater, it is the dead matter of marine organisms

Where does energy of Hydrogen Fuel cells come from?

Energy input (fossil fuel, solar or wind) splitting Water into hydrogen and oxygen

Where does nuclear Power come from?

Energy that holds neutrons and protons together in Uranium

Disadvantages of using Fossil Fuels

Excessive CO2 emissions leads to green house effect and greenhouse effect Chemicals lead to air pollution and acid rain Habitats are destroyed in mining and drilling

Disadvantages of Solar Energy

Expensive to set up Weather dependent- no sunshine = no energy Useful only in sunny environments (determined by latitiude) and cloud cover

Energy Transformation diagram of Solar Power

Light --> Electricity

Disadvantages of Wind Power

Limited to high wind areas Weather dependent Affects view of landscapes

Where does Coal come from?

Mined underground, it is the dead matter of prehistoric plants

Energy Transformation diagram of Wind Power

Motion --> Electricity

Advantages of Wind Power

No is CO2 is produced Wind is renewable

Energy Transformation diagram of Nuclear Power

Nuclear --> Heat --> Motion --> Electricity

Disadvantages of Hydrogen Fuel Cells

Requires production of hydrogen fuel Very expensive

Advantages of Nuclear Power

Several million more times energetic No CO2 emission

Disadvantages of Nuclear Power

Storage of radioactive waste is tricky, since it is hazardous to the environment (radiation) They are currently stored in pods and dry casks deep inside the Earth Risk of meltdown can devastate environment for decades

What are the renewable sources of energy?

Sunlight, Wind Power, and Hydrogen Fuel Cells

Describe the process of how fossil fuels produce electrical energy

The fuel is burned in a boiler, which heats up water going through pipes, turning it into steam. The motion of the steam particles then move parts of a turbine. This energy is converted to chemical energy inside a generator using electromagnetism.

Fission

The separation of the neutrons and protons in Uranium, releases seven thousand times more energy than coal

What sustainable resource use?

Where our consumption of resources can continue forever without damaging the environment.

How is energy produced by the generator?

a magnet rotates inside a coil of copper to excite electrons
