best electric hybrid cars uk image
Lee
I've been searching for details on hybrid cars.. All I found is hybrid cars use electric motor and gasoline engine.. There is a parallel type, series type, etc ..
Definition of hybrid cars?
What are the advantages and disadvantages of hybrid cars?
What is the rate of hybrid cars sold? ( preferably in UK )
I really need help with my school project....... Thanks in advance :D
Answer
A hybrid car is a combo of gas and electric.
Advantage- great on gas and good for the economy
Disadvantage- maybe a little more expensive.
Rate sold in UK- Have no clue

How environmentally friendly is it currently to charge an electric car?
Jeff P
We all know that there is a tremendous benefit to driving a zero-emissions electric vehicle, but that electric charge still comes from a coal fired power plant, in most places.
Can anyone steer me towards any info that shows that, even with the current 20th century methods of mass producing electricity, charging and driving electric cars is more environmentally friendly than normal high mpg gasoline burning cars?
Thanks!
Answer
Electric motors & batteries are much more efficient than combustion engines. Current engines are about 12-20% efficient, whilst electric motors can be 90%+ efficient.
From then it depends on how efficient your power station, grid and batteries are. The latest Economist quotes, per kWh, a combustion engine can drive 1.5-2.5km, a diesel hybrid 3.2km and an electric car up to 6.3km.
Anyhow, the Chevrolet Volt claims to drive 64km on a charge of 8.8kWh:
http://en.wikipedia.org/wiki/Chevrolet_Volt
Or about 0.14kWh/km.
CO2 emissions from a coal power station are somewhere between 900-1300g/kWh. Assuming a relatively new power station it's about 900g:
http://en.wikipedia.org/wiki/Carbon_footprint#Carbon_footprint_for_various_types_of_electricity_production
So a km driven in the Volt on coal powered electricity is just under 125g CO2.
A similar sized car, the UK's Ford Focus Zetex, gets 155g CO2/km. Small cars and hybrids get lower, though.
The UK grid electricity average is about 430g/kWh and in the US it's under 700g. So a Volt in the UK currently gets 60g/km, lower than any marketed petrol or diesel car. In the US it's under 95g.
In France (mostly nuclear) it's something like 15g/km, over 90% lower than the Focus.
CO2 emissions from electricity in many developed nations will probably fall too because of efficiency and global warming concerns.
The UK is planning 30% renewable electricity and a new generation of nuclear power stations, and coal power stations can't be built without capturing part of their carbon.
