Hybrid cars my question is as the cars have two power units how much extra pollution?
Answers:
I think they are a politically correct waste of space. My neighbour has a Toyota Prius Hybrid and it has worse economy than my wife's 306HDi for the same journey profile. Plus there is the environmental impact of recycling/scrapping the batteries.
I brought a Toyota Prius and was very smug about how much better it was for the environment (I only do a few thousand miles a year anyway).
Then I saw Newsnight a couple of months ago and discovered that the extra carbon from production broadly cancels out the carbon saved on fuel over the average lifetime of the car. So I'm not so smug anymore.
probably right now overall they are quite inefficient, once they become the standard mode of transport then manufacturing will improve as the technology advances and provide less waste/pollution.
still i don't see a normal petrol car driving 150000 miles in its lifetime producing less pollution that it takes to make an electric motor.
My own car so far will have burned up around 3000 gallons of petrol in its life.
That is a good question, I had not given that any thought.. Of course they do have to manufacture the electric motor, then manufacture the batteries, then energy must be used to originally charge the batteries, then there is a disposal issue when the batteries must be replaced. My 4 cyl Ford Fusion has just as high of a pollution rating (California) as a hybrid.. and cost a lot less money.
actually there is less pollution than there is on a regular fueled vehicle ,because of the way they operate ,the pollutants are much less,and it only makes good sense when you think about it,your only burning half the fuel as normal but its a good idea,, it just should have been around ten years ago,but I'm sure they,ll get better as time goes on,,good luck,i hope this help,s.
hybrid cars have a petrol engine and a electric engine, both smaller than the average car engine thus saving petrol, but even more so due to the fact power for the electric motor is from the kinetic energy from the petrol engine-only! and because most cars use most petrol at traffic, the electric engine is used most of the time and the petrolengine only kicks in when power is needed. thus meaning use of petrol is in fact very little. this is the best formula currently available with hydrogen etc. along way .. making the car in the first place does in most cases cause pollution but people will still buy cars and if hybrid cars can significantly reduce our pollution levels then thats for the good of the world. the manufacture of the car is so small to the pollution a normal car makes in a lifetime.
