Outline

Global warming is caused by the emission of greenhouse gas.

72% of greenhouse gas is carbon dioxide (CO2).

Greenhouse gas conposition

CO2Others

The emission of CO2 have been increased within the last 50 years

The emission is still increasing by almost 3%.

CO2 emission world-wide

CO2 emission world-wide

CO2 is released to the atmosphere where it remains for 100 to 200 years.

This leads to increasing of CO2 in atmosphere, which causes the average temperature on Earth to raise.

Focus on CO2 emitted by car.

There are two main eco-car.

1. Hybrid car 2. Electric car

In order to decrease CO2…

What difference between Hybrid car and Electric car?

Hybrid car

Hybrid car creates some of its power from a conventional gasoline engine.

It emits a little CO2

Electric car

Electric car creates its power from electrical sources.

　 Completely non- 　　　　 pollution, zero-emission car

Eco-car is invented, using much research expenses.

Its price is very high.

Consumers doesn’t want to buy it.

DC:How press consumers to buy eco-car?

There are some problems…

Thailand’s government

Eco-car 　　 consumer

Very expensive 　　　　 subsidy

　　　　　　　　　　　　　　　　　 government

Some organizations

If we use Electric car, we must generate electric power.

But, using thermal power generation

CO2 will increase

DC:How generate electric power without emitting CO2?

Second problem
