Its is a known fact that cars are one of the major contribution for green house gases. So recently the car manufactures come up with a new Eco friendly car, which is the hybrid cars. So my question is, if the global population adopt to hybrid car, can global warming be prevented?

yes but its expensive though

No. hybrid cars still produce CO2.
We need cars powered by renewable energy to prevent global warming getting any worse, although hybrids are partially they still produce greenhouse gases, although quite a bit less than purely petrol or diesel powered cars
There may not be a way to stop global warming,

This is not a simple answer.
Hybrids still use gas so you still have emissions, pollution, noise etc.
Total electric cars have no emissions, zero pollution, no noise.
The problem is most only go about 50 MHP.
You do save a ton of money because we have less moving parts, take no gas, no oil, you charge them at night where energy cost are at the lowest levels so it ends up costing you about 2 cents a mile to drive an electric car.
They are priced around $10,000 brand new and com in different makes and models.

Hybrids (at least ones that are built for mileage) emit less CO2 when operating, but take more energy to make, so it tends to even out. The bigger problem in much of the first world is people want cars that are too big. We use a car when we could use a scooter, and we use a scooter when we could walk or bicycle. Much more CO2 could be saved by people finding ways to do without their cars at all.
We will not stop global warming, even if all of it is caused by man. To stabilize CO2 levels where they are now would require cuts in energy use that would turn the US and Europe into third world nations and destroy the worlds economy. Therefore, we won’t stabilize the emissions, and CO2 levels will continue to rise until fossil fuels become so expensive that we can’t afford them any more.

No. Hybrids are a step in the right direction, but while they emit less CO2, they still burn gasoline and they still emit carbon dioxide, which causes global warming.
If everyone drove a hybrid instead of a regular gas car, we would reduce worldwide greenhouse gas emissions, but not nearly enough to stop global warming.
Electric cars would reduce emissions even further, although they also are responsible for some CO2 emissions because some of our power comes from coal power plants, and burning coal emits CO2 as well. However, electric cars create less CO2 emissions than even hybrids.
In addition to switching to hybrids and electric cars, we need to take more steps. For example, becoming more energy efficient, swithing to renewable power plants and getting rid of coal power plants, biking and using public transportation, etc.

The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.
However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00
Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I’ve converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I’ve also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.
If you’re interested here’s what it would entitle…
- The engine compartment is first cleaned out of any gasoline components.
- Electric components are then installed in exchange.
- A battery bank is built and incorporated.
- Existing starter and driving systems are connected.
- Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
- The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.
The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.
Typical tools, hardware & supplies are used, making access to parts available for all.
Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.
Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com
My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you’d need…
Advanced DC Motor
The motor is an 8″ Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.
Adaptor plate
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.
DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.
Potbox (Potentiometer)
The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox’s lever arm is attached to the existing accelerator cable.
Main Contactor
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.
Circuit Breaker
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.
Main Fuse
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.
Shunt
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.
Charger interlock
A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.
DC/DC Converter
The DC/DC converter is similar in function to a gas car’s alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.
If you interested I offer several DIY alternative guides to walk you step by step threw EV conversion process at agua-luna com or
www agua-luna com
Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

no difference at all for global warming, its all a big com

NO, cars will do nothing to change the climate. Just as we have done nothing to change the climate. If you want the climate to change, sit back and wait 100 years and the climate will change as it always has.

I don’t recall Al Gore mentioning them in An Inconvenient Truth…
Do you?
