With no imminent resolution to the oil crisis in the Middle East, the price of crude oil has raised well over one hundred dollars, and will only continue to rise. Gas prices are now reaching above four dollars per gallon, and consumers around the world are looking for ways to save money on gas, as well as reduce their impact on the environment around them in this era of speculation about global warming.

There are quite a few ways that drivers are able to conserve gas while driving their current vehicles. The most obvious option is to cut down on the number of hours spent driving the car. Of course, this isn't a viable option for most people, especially in rural areas, but walking or riding a bike is a great way to save money and stay healthy.

Other conscious decisions including having your vehicle coast down hills, and avoiding stopping and starting. Driving on a busy street during rush hour is a great way to guarantee your car is burning gas.

As consumers are changing their driving habits, they have shied way from SUVs and other large gas-guzzling vehicles. With the decision to move away from trucks, vans, and SUVs, the automobile manufacturers around the world have introduced a variety of alternatives.

Hybrid cars minimize the consumption of gasoline by using an electric motor when possible. These hybrids greatly improve the efficiency of energy used by the car. Despite general belief, hybrid cars are easy to refuel and provide all of the typical function of our current gas-fueled cars, but with far less impact on the environment and driver's wallet.

Interested in how hybrid cars make the most out of every gallon? Hybrid cars shut off the gasoline engine when possible, and recover energy when the vehicle when brake. In addition, their sleek aerodynamic design and light materials allow them to further cut down the burning up of gas.

While hybrid cars are allowing consumers to make an impact now, the future of cars is decidedly based on hydrogen cars. Hydrogen cars are the holy grail of transportation. Just like hybrid cars, hydrogen cars use minimal energy consumption and will eventually have impact on the environment.

Research for hydrogen cars has been funding both by the government and private investors. For the time being, functioning models are demonstration-only as the cars are still expensive to build and operate.

Unfortunately there are still many drawbacks with hydrogen vehicles. Only a couple hundred are currently in use in the United States, due to their high costs. Because hydrogen vehicles have yet to hit the mainstream population, mechanical assistance is inconvenient. In addition, hydrogen cars create more exhaust than gasoline-powered.

Once hydrogen cars become more prominent in the United States, there will be need for many more hydrogen stations used to fuel cars. It has been approximated that the cost will be around $500,000,000,000 (five-hundred billion dollars) to replace the nation's current gasoline-based infrastructure. However, because of the global gas and oil crisis, the investment is still considered a necessary one.

Before consumers know it, energy-efficient cars will become the norm on the market, not the exception. Hybrid cars are no longer taboo, and we can anticipate hydrogen cars to follow sooner than we think. While the prices of oil and gasoline may improve, expect to find financial relief with these new innovations.
