MOBILITY IN THE HUMAN SOCIATY

AND ITS ENERGY CONSEQUENCES

Content.

Contemporary energy consumption in the society.

How much energy is today for the mobility used.

What is role of automobiles in total mobility.

What is perspective of the automobile grow up?

Energy consequences.

Harmful influences for the environment.

Can climate be changed by these influences?

What is the role of engineering under these conditions?

Conclusions.

Contemporary energy consumption in the society.

Survey of energy consumption and its grow during 16 years is on the picture.

OECD is Organisation for Economic Cooperation and Development:

(34 importent states are included from Europe, America, Asia and other world parts.

Energy consumption in OECD,

North America and Europe

Energy consumption in OECD, North America and

Evropy

Energy consumption in years 1999 - 2009 in Czech Republic.

In Czech Republic the energy consumption during years 2006 a 2007 sank.

But the energy consumption for mobility rises steadily and is near 30%.

Role of automobile transport in total mobility.

Partial conclusion in this moment:

Contemporary mobility consumes 30% of total energy used on the world.

Very high energy consumption is consumed in road transport.

Automobility produces the highest consumption part for human mobility.

And we should add the quickly growing automobile number

in the world.

It can be expected that between ears 2015 and 2040

2 milliards automobile can be on the world.

How we ensure energy for mobility?

Energy for mobility that is overland mobility, sea mobility and air mobility

comes from rude oil burning.

Consequences are as follows:

Crude oil resources are on the world unequally divided.

That causes effort to ensure for the national economy access to them

and sharpens the political nervousness.

Green gas production is really high. It is unpleasant for cities. Papers even

arose that it can influence the Earth climate. I am not able to accept it

neither to refuse it. But nevertheless think we a little on it.

Annual Carbon Emissions by Region.

USA Canada

EAST EUROPE

WEST EUROPE

CHINA

INDIA

AFRICA

Emission curves are very similar all over the world. They are only shifted.

That means: When nothing will be done the situation will be worse.

Can the human activity change the climate?

Temperature rise on the Earth during 120 years

Glacier melting measurements confirm

It is broadly accepted that we live in period of climate worming.

But what are the reasons?


Mobility in the human sociaty and its energy consequences

Katedra elektrických pohonů a trakce K 314 - ČVUT Praha

But what are the reasons?

1.Is it caused by human activity?

2.Is it caused by other physical reasons?

Earth climate changed in the past, is changing now and will change in the future,

Glacial and interglacial cycles are known. Some theories attempt to explain them

but till now they are not fully explained.

Nevertheless the human influence is here and cannot be refused..

Definite answer to this question does not exist.

May be that what is measured and what is watched

is a result of both these phenomena's.

WHAT TO DO ?

Electrical Engineering on the world, and in China specially

is developing electric hybrid and fully electric vehicles.

Also at CTU in Prague the Research institute works on this theme.

Let us describe the benefit and problems of this solution.

Influence of hybridization on energy efficiency usage

When a vehicle is moving on New European Driving Cycle.

Efficiency rises from 30% to 38% that means approximately plus 20%.

Efficiency of full electric driven vehicles reaches 70%

The hybrid vehical deminishes the CO2 production.

Full electric vehical does not produce CO2 on the place where it is driving..

But CO2 is produced in electric plant from which batteries are charched.

Conclusion

Mobility is the largest energy consumer30% from total energy consumption.

Road traffic (automobiles)80% from mobility energy

Energy for road traffic is gained from crude oil

Oil is nonreversible energy carrier. Energy sources are objects of international interest.

Annual Carbon Emissions are 6400 metric tons

We live in time of climate worming.

Reasons are not known

CO2 production is so high that it could be one of serious reasons.

Scientific development brings significant results

Hybrid vehicles diminish fuel consumption and emission production 10%

Electric vehicles have energy efficiency as much as 70%.

Emission production is 80% lower

Action radius is only approximately 150km.

Úrovně nabíjecích výkonů v závislosti na velikosti vozidla a nabíjecí době

  • Potřebné nabíjecí výkony pro rychlé nabíjení elektrických vozidel již nejsou běžně

  • dostupné v domovní napájecí síti.

  • Pro tyto výkony je nutné vybudovat speciální nabíjecí stanice s přípojkami na úrovni

  • VN 22 kV.

  • Než bude tato infrastruktura vybudována, najdou uplatnění autarkické hybridní

  • pohony (HEV), které nevyžadují žádnou změnu infrastruktury.

  • Řešitelné jsou pouze PHEV s nabíjecí dobou 6 -8 hodin výkonem cca 2-3 kW.
