What is Energy ?

 The word energy derives

from the Greek ”energeia”

 First appears in 4th century BC

 Understood as the ability

a physical system has to

do work on other physical

systems

What is Energy ?

 Two kinds of Energy

 Renewable

 Non-Renewable

What is Energy ?

• Renewable energy

 Solar

 Hydropower

 Biomass

 Water

 Geothermal power

Renewable Energy

 Advantages

 Disadvantages

 Depends on the weather

 Difficult to generate the quantities of electricity

What is Energy ?

 Non-Renewable

 Natural gas

 Petroleum

 Uranium

 Propane

Non-Renewable Energy

 Advantages

 Relatively cheap fuel and

readily available

 Disadvantages

 Can run out

 Photochemical pollution from nitrous oxides, and acid rain from sulphur dioxide

 Greenhouse gases including vast amounts of carbon dioxide that causing the phenomenon of global warming that the planet is currently experiencing

How Energy is used ?

 Four economic sector

 Residential: heating and cooling our homes…

 Commercial: lighting office buildings…

 Transportation: driving cars and moving freight …

 Industrial: manufacturing the products …

Energy industry

 The petroleum industry

 The gas industry

 The electrical power industry

 The coal industry

 The nuclear power industry

 The renewable energy industry

 Traditional energy industry

How Energy is used ?

 World Energy Consumption

Energy consumption in Vietnam

 According to the industry

trade ministry:

 Vietnam’s power

consumption is likely to

increase by 3.5 times within

the next decade

 Crude oil, gases and some

other fossil fuels will be

exhausted within 30 years

 Need to import 100 million

tons of fossil coal each year

by 2020

Energy conservation

 Increased efficient energy use

 Decreased energy consumption or reduced consumption from conventional

energy sources.

Energy conservation

 The limited amounts of non-renewable energy resources on Earth

 Consumption of non-renewable resources impacts the environment

Energy conservation in Vietnam

 Energy conservation

measures have

successfully saved the

nation more than

240billion VND in

electricity costs in the

first six months of 2007

Sustainable Energy

 Sustainable energy resources are most often

regarded as including all renewable energy sources

 Hydroelectricity, solar energy, wind energy, wave

power, geothermal energy, bio energy, and tidal

power

 Includes technologies that improve energy efficiency
