HYBRID CARS: THE BEST OR THE WORST CHOICE?

CLAIM 1
Hybrid cars can help to save money.

REASONS: Hybrid cars use combination of fuel engine and electric generator which consume less fuel.

EVIDENCE: You won’t have to spend as much money on fuel. Hybrid cars have an electric motor as well as a gasoline engine. The gasoline engine is not engaged during low speeds, which saves money on your fuel costs. (page 1, paragraph 1, line 1) http://www.easy-green-living.org/advantages-disadvantages-hybrid-cars.html

OBJECTION 1
Hybrid cars do not help to save money

REASONS: Hybrid cars are much more expensive than conventional cars.

EVIDENCE: The biggest disadvantage of hybrid cars is that they are still fairly expensive, namely the production of hybrid cars still has relatively high costs. Hybrid cars therefore usually cost in range from $2,000 to $5,000 more than their non-Hybrid versions. The high costs of hybrid cars are usually the results of using very rare materials in their production (for instance dysprosium used to fabricate many of the advanced electric motors and battery systems in hybrid propulsion systems, and neodymium used as a crucial ingredient in high-strength magnets that are found in permanent magnet electric motors). (page 8, paragraph 4, line 1) http://www.renewables-info.com/drawbacks_and_benefits/hybrid_cars_advantages_and_disadvantages.html

CLAIM 2
Hybrid cars help to reduce pollution.

REASONS: Hybrid cars emit low emissions.

EVIDENCE: There are two main advantages of hybrid cars compared to traditional cars, one is lower CO2 emissions, and therefore less impact to global warming (the environmental advantage of hybrid cars), and the other is higher fuel efficiency that can save you sufficient amount of money over the years (economic advantage of hybrid cars). In times when gasoline was fairly cheap improving mileage wasn't something many people were worried with, but at these uncertain economic times, when almost any dollar matters fuel efficiency has become rather important advantage that hybrid cars have over traditional cars.

OBJECTION 2
Hybrid cars do not help to reduce pollution.

REASONS: Hybrid cars still burn gasoline and emit greenhouse gases.

EVIDENCE: The usually gasoline powered internal combustion engine still releases compounds such as Nitrogen monoxide (NO), Carbon monoxide (CO), and Carbon dioxide (CO2). These gases are dangerous in many ways. Nitrogen monoxide when released into the atmosphere will combine with water vapour. This forms Nitric acid. Later, this Nitric acid will fall with rain to wreak havoc with the environment, mostly by upsetting pH balances. Carbon monoxide is an odourless and colourless gas that is deadly to humans in any appreciable amount. The reason for this is that CO more readily bonds with the haemoglobin in our blood than oxygen. (page 3, paragraph 1, line 1) http://debatepedia.idebate.org/en/index.php/Argument:_Hybrid_cars_still_burn_gasoline_and_emit_greenhouse_gases

CLAIM 3
More and more people are using hybrid

REASONS: Hybrid car is the best option for environmental reason and fuel efficiency.

EVIDENCE: Hybrids are a very popular choice these days among conscientious car buyers and it is not difficult to understand why. Of course, the environment could be only a secondary consideration given the rising cost of gasoline and the measures that...
