Global warming is a major issue today in the United States, and lately it seems that news has more than ever happened. In 2008, a key election year, any major or small candidate in office should not be concerned with fuel conservation, carbon dioxide emission reduction, and alternative energy sources. New and used cars and trucks both burn gasoline to allow movement and fuel burning in the United States is a major source of carbon dioxide emissions. Over time, the cumulative effects of global warming may include a significant increase in Earth's temperature; the melting of polar ice caps, as well as severe weather events resulting in material destruction and loss of human life. One of the easy ways to reduce CO2 emissions is to reduce the amount of fuel burned daily, monthly and annually.
Americans who live in bigger cities – such as New York, Pittsburgh, San Francisco, Baltimore or Atlanta – can often reduce public emissions by reducing their annual carbon footprint by public transport. According to estimates by the US Association for Public Transport, annual fuel savings of $ 1.4 billion are saved. However, many Americans do not live in areas where the metro, bus or car is available or convenient. Some US suburbs have been too sparsely populated to support extensive public transport; Meanwhile, many of the exurban area's infrastructures are in no way capable of supporting the bus or light rail system. In order to effectively reduce US CO2 emissions, each driver must find a solution to the over-consumption of passenger cars, including the use of cars, lorries and SUVs.
In March 2004, the US Environmental Protection Agency (EPA) announced the first "advanced hydraulic hybrid" SUV production. NextEnergy, a Michigan nonprofit organization, states that hydraulic hybrid cars, trucks and SUVs use a regenerative braking system. This means that when a hybrid driver stops his car, truck, or SUV, the vehicle's engine pump the liquid from a low-pressure chamber into a high-pressure chamber. The pumped fluid is hydraulic and is capable of compressing nitrogen in the high pressure chamber on the braking system. As the system is under pressure, energy is stored by a system battery used for vehicle acceleration or other driving modes.
Hybrid cars, trucks and SUVs are a landmark inventions. By capturing the otherwise lost kinetic energy during the vehicle braking and using this energy to charge the vehicle's battery, hybrid vehicles reduce the total amount of petrol that the car, truck, or SUV needs to burn. Therefore, this kind of technology saves significant consumer consumption. In a number of hybrid vehicle models, the petrol engine stops completely during stoppages, resulting in fuel consumption in the vehicle
Global warming is, however, much more complex than carbon dioxide emissions. Chemical compounds generated by fuel production and use contribute to the greenhouse effect or to the surface temperature of the Earth that is emitted from the heat gases in the atmosphere. It is well known that combustion of gas emits CO2 into the atmosphere. However, many other principles of natural gas contribute to the greenhouse effect.
In addition to CO2 emissions, combustion of gasoline emits nitrogen oxide (NO2) into the atmosphere. According to the Intergovernmental Panel on Climate Change, NO2 has 296 times the long-term impact of the CO2 ratio. Therefore, this compound, although less discussed than CO2, is another harmful byproduct of fuel consumption. Furthermore, fuel production itself contributes to the harmful compounds in the atmosphere. Methane gas (CH4) is released during fuel production. IPCC estimates that methane has a serious impact on global warming – the Earth is warmed up by 25 times as many CO2 units as it is for a long time. Car manufacturers and train drivers can easily conclude that fuel production and consumption have significant, long-term consequences for the Earth's life.
During the driving process, there is considerable potential for fuel waste when a car, truck or SUV stops the engine running; such as a light or an intersection. The hybrid engine reduces the amount of gasoline and all chemical atmospheric emissions since the engine power of the engine is stored when the vehicle is idling or at a low speed. Smaller, more fuel-efficient hybrid engines allow them to reduce greenhouse gas emissions by using less gasoline. Of course, consumer pockets make a big use of reduced fuel consumption. More importantly, experts from institutions such as the Environment Agency and the Intergovernmental Panel on Climate Change estimate that hybrid vehicles will reduce or halt the impact of greenhouse gases on Earth.
