Which contributes more to global warming, coal or petrol

Question

******

Right now, coal and petrol are about even. Here is a graph: http://en.wikipedia.org/wiki/Image:Global_Carbon_Emission_by_Type_to_Y2004.png Coal has probably passed petrol since the graph was made. Over the next 15 years, we can expect coal to take an increasingly larger share.

Answer 1

CO2 is not  the problem as the plants have already recycled most of it...

Answer 2

Petrol is the major contributor, the harmful gases like carbon dioxide other harmful gases like sulphur, nitrogen and hydrogen along with some other harmful harsh chemicals released when petrol burns causes more harm to the ozone layer.  

Answer 3

co2 based emmsions:

coal based industry 39 percent

petrol based transportation 28 percent

However petrol is far more harmful with more pollutants.

For the poster above me....how can you say that "as for CO2 the plants..." have recycled the majority....

ARE YOU MAD...with all the deforestation...poorly designed xeriscapeing..loss of grass lands...WHAT FING PLANTS? in case you didn't notice...they are going buh bye!

Answer 4

agreed with karazyal!

Moreover global warming is observed on Jupiter and its moon Europe; one more ‘red eye’ is forming in Jupiter’s atmosphere!

Answer 5

Mother nature contributes more to global waming!  

Global warming is a natural occurrence.  Our earth has had probably a million global warming's in our past history - this is just one more!

Coal or petrol - doesn't matter!   Human beings put out forest fires, with fewer forest fires polluting the air it's a wash!   The production of "meat" produces more harmful stuff in the air than automobiles!   The production of "meat" means food from beef, chicken, ducks, goats, sheep - any animal that we raise to slaughter and eat - produces more harmful c**p in the air than gasoline engines in cars!

The short answer is that if there were no Suv's and no gasoline burning motors, no coal fired furnaces and NO HUMAN BEINGS on earth we would still have global warming take place!   Global warming is taking place on Mars right now and how can this be with no coal burning furnaces, no gasoline engines and no humans??

Answer 6

Worldwide I believe it's coal.

Answer 7

as far as Mans contribution goes

definitely the burning of coal

Answer 8

Human use of these.

Answer 9

coal

Answer 10

I think is is coal right now, most of which is used for electricity generation.  Nuclear may help reduce CO2 but there is the problem of waste disposal to deal with.  Natural gas is a cleaner alternative. Hydro-electric and geothermal are good alternatives if the resources are available and not to disruptive.  Flow resources (wind, solar, wave) are ultimately the most desirable for electric generation .  We need to greatly diversify our sources and maybe use coal and gas when flow resources are not working well (cloudy and low wind) as backup.

Petroleum could become larger in the future as more cars are available in developing countries.  Again, maybe use petroleum for farming and big equipment, and electric or hydrogen for personal transportation.  It is a question of allocating a resource to best benefit society.

The free market economy would do this is we actually knew the true environmental costs of using petroleum.  This is a bugger to measure and changes over time and population, but we are getting some ideas about true costs now.
