2. 1 Cause of global warming-CO2- 2 The way to decrease CO2-eco car- 3 The problems of eco car 4 Organization 5 Discussion question

3.  Global warming is caused by the emission of greenhouse gas.  72% of greenhouse gas is carbon dioxide (CO2).

4.  The emission of CO2 have been increased within the last 50 years  The emission is still increasing by almost 3%.

5.  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.

6.  Focus on CO2 emitted by car.  There are two main eco-car. 1. Hybrid car 2. Electric car

7. 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

8.  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?

9. Thailand’s government Eco-car consumer Very expensive subsidy government

10.  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?
