Energy by Mind Map: Energy

1. Types of energy

1.1. Forms

1.1.1. kinetic

1.1.1.1. is the energy that an object possesses due to its movement. It is the work needed to accelerate a body to its stated velocity.

1.1.2. potential

1.1.2.1. is the energy that is stored in an object or substance . When the position or state of the object changes , it is realesed.(for example , in a falling rock , the potential energy will be converted to kinetic energy) .GR

1.1.2.2. Types: Gravitational Energy and Elastic potential Energy

1.2. 1.

1.2.1. Radiant Energy : it's a form of kinetic energy and can take the form of visible waves(light energy or invisble waves such as radio waves or x-rays). GR

1.3. 2.

1.3.1. Kinetic Energy: it includes radiant and electricial ernegy

1.4. 3.

1.4.1. Heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases..

1.5. 4.

1.5.1. Chemical energy is stored in the bonds of atoms and molecules. Stored chemical energy is found in food, biomass, petroleum, and natural gas.

1.6. 5.

1.6.1. Electrical Energy : Ekectrical energy is a type of kinetic energy caused by moving electric charges. GR

1.7. 6.

1.7.1. Nuclear energy is stored in the nucleus of atoms. Nuclear power plants split the nuclei of uranium atoms to produce electricity.

1.8. 7

1.8.1. 7. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases.

1.9. 8

1.9.1. Sound Energy: It is the movement of energy through subtances, which moves in waves and is produced when a force makes an object vibrate.

1.10. 9.

1.10.1. Gravitational Energy: it's the energy stored in an object due to its height above the Earth. It is a form of potential energy associated with the Earth's gravity. GR

2. Why to save energy?

2.1. Because we reduce the threats that fossil fuels pose to our ecosystem. GR

2.2. Conventional energy sources are not infinite and also saving energy means saving money.

2.3. Less CO2 means stopping global warming, we are responsible for the earth - we can sustain ourselves

2.4. It saves you money at home and improves National economy.

3. Non Renewable sources of energy

3.1. Types

3.1.1. Fossil Fuel/ Oil

3.1.2. 2.Coal

3.1.3. 3. Wind power.

3.1.4. 4. Natural Gas. GR

3.2. Pros

3.2.1. always accessible (in comparison to wind for example), currently cheaper

3.2.2. Currently cheaper, sometimes easier to work with, more accesible

3.2.3. 3 Most nonrenewable sources of energy are easy to transport from one area to another. For example petroleum oils which can be transported via pipes.

3.2.4. 4. They can be easily transported e.g using underground pipes. GR

3.3. Cons

3.3.1. they are finite, they won't replenish for a long time, environmental damage, getting to them destroys the environment

3.3.2. 2.They can cause health problems such as t lung problems and asthma attacks in humans.

3.3.3. 3 Produce harmful green house gases which contribute global warming.

3.3.4. 4.Once they run out, they can't be renewed for million of years. GR

4. Renewable sources of energy

4.1. Types

4.1.1. Biomass

4.1.1.1. energy in organic matter (trees,plants,crops,animal waste) that comes from the sun.GR

4.1.2. Wind energy

4.1.3. Hydroelectric

4.1.4. Geothermal

4.1.5. 4.Solar energy

4.2. Pros

4.2.1. 1. They provide clean energy which does not contribute to global warming.GR

4.2.2. clean energy, wind is renewable, it's quiet, it takes up less space than solar power

4.2.3. They can produce so much energy as non renewable ones, so there's no energy enough for everyone.

4.3. Cons

4.3.1. no wind = no energy, it harms animals like birds or fish (if it's built in the sea), saving and distributing the energy can be difficult

4.3.2. They often rely on weather conditions which means they cannot offer a reliable or consistent enrgy supply.GR

4.3.3. There are heavy upfront costs associated with both geothermal power plants and geothermal heating/cooling systems.

4.3.4. It will be difficult to generate large quantities of electricity as those produced by the traditional fossil fuels.
