Direct emission is emission directly from the car. 
To produce the electricity for the EV's power-plant's emit carbon instead of the car. Using green energy sources helps to reduce carbon emission.

The EV's are still greener than combustion engine cars because they are more efficient. EV's use 80-90% of the energy compared to 20-30% for regular combustion engines.

EV's carbon emission depends on the electricity production's emission. If this is low the EV's emission is low and vice-versa.

Lithium, which is used in batteries, is harsh on the environment to extract.

The first electric vehicles were created by inventors when oil was hard to find and expensive. Electric cars became more popular by the turn of the 20th century, because they were more efficient and cleaner than gasoline-fueled cars.

1911
Inventon of the starter motor for the petrol car, meant that electric cars became less popular again.

First World War
Vastly improved reliability of petrol cars aswell as Ford's innovation in efficient production methods whittled away the price advantage of electric cars.

1960s and 1970s
An oil crisis sparked a new wave of interest in electric vehicles (EVs), but this was short lived as the fuel prices dropped again.

Mid-1990s
GM's EV1 was invented, which sparked hope of an electric revolution, but it was scrapped a decade later.

Current
Consumer and government demands for cleaner more efficient vehicle, have made manufacturers design new hybrid- and electric cars.

Future
China and the US intend to have a million EVs on the road by 2020.]]> 2016-11-02 08:56:31 UTC https://padlet.com/jd19/arpuw4j6ga34/wish/134693837 jd19 https://padlet.com/jd19/arpuw4j6ga34/wish/134693886 - Electric is not the only alternativ to gas.
Alternativ to gas are:

Bio-diesel (diesel)
- Most widely used
- Made by grease and oil, vegetable oils and animal fats

Ethanol (E85)
- 51 to 83% ethanol
- ethanol is formed naturally from plants

Hydrogen Fuel Cell
- Zero-emission, only leaves behind harmless water vapor

Compressed Natural Gas
-Liquefied form
- Natural gas is more cleaner than alternativ fuel

Propane
- Called "Auto-gas"
- Mixing butane and propane
