The currently used batteries in electric cars are usually the lead-acid type, which are heavy and bulky. A lead-acid battery pack in a typical electric car weighs about 1000 pounds or more; it also occupies a large space as about 50 batteries each of size 6" x 8" x 6" are required for a single car (Brain, 2006). They are also expensive as a typical lead-acid battery pack for an electric car costs about $2,000. Moreover, batteries get discharged quickly and give only about a 50-mile range to a car, after which the battery-pack has to be re-charged. The re-charging process is also time-consuming and it takes between 4 to 10 hours for full charge, depending on the battery technology and the charger (Ibid). Such batteries also have a relatively short life and have to be replaced in about three to four years.
Recent development in battery technology has now made it possible to use batteries such as the NiMH type in electric cars. These batteries give a greater (about double) range to the car and also have a life of about 10 years. They are, however, much more expensive as an NiMH battery pack for an electric car costs about...
On the other hand, the convenience and cost-effective performance of gasoline-powered vehicles are well established.
In conclusion, it can be safely said that the problem of battery-size, high cost, and recharging issues make electric cars unviable alternatives to fossil fuel vehicles in the foreseeable future. As a result, the fossil fuel vehicles are going to last a lot longer than is often predicted.

The limited oil-refining capacity is the result of lack of investment attributable to decades of depressed oil prices in the 1980s and 1990s when oil prices fell below $10 / barrel.

By studying this history, one can quickly understand fossil fuels are in such short supply. Although they have been around for millions of years, they have been in use for thousands. Fossil Fuels' Uses While it is common knowledge that fossil fuels are used as energy sources and in a variety of material productions, the degree to which fossil fuels are used on a daily basis is monumental. Both oil and
Business Nuclear power, under current conditions, is characterized by much lower regular emissions compared to energy from fossil fuel burning. But, it poses its own unique hazards, of which the most notable is risk of industrial accidents (e.g. Chernobyl) that have acute, long-term repercussions over huge areas. There are also security risks presented by vast inventories of materials that have the potential of being utilized as nuclear weapons; fossil fuels pose
Energy of the Future There is no doubt that petroleum and coal are the dominant energy sources of today. However, there is also no doubt that those two energy sources really need to fall by the wayside given how they pollute the earth and how they are ostensibly affecting the entire global climate in the form of greenhouse gases and the like. However, actively and completely replacing those two energy sources
Fuel Cell Technology There are over 600 million motor vehicles in the world today. If present trends continue, the number of cars on Earth will double in the next 30 years." ("Cars Emit") As the demand for energy increase and resources, such as fossil fuel, decrease alternative must be sought. Of these alternatives, hydrogen fuel cell technology, in automotive applications, has significant benefits and is now technologically feasible. Given this knowledge,
technology for hybrid vehicles is proven to work, we as a nation should only build and sell hybrid vehicles to help reduce the damage done to the nation's air quality. Hybrid Electric Vehicles (HEVs) have reached the point that they are affordable for most drivers, they use less energy, and they are cleaner than gasoline and diesel powered vehicles. These vehicles make sense for today and for the future,
Reasoning for Alternative Fuels All other things being equal, the energy source with the lowest cost will always be pursued after in the cargo transportation world. The supremacy of petroleum-derived from fuels is an outcome of the comparative ease with which they can be stored and competently used for the internal combustion engine vehicle. Other types of fossil fuels (propane, natural gas and methanol) can be used as transportation fuels
