Green cars have been growing in popularity the last decade or so, and not just due to environmentalists or people who want to limit their carbon footprint. Green cars are not only more eco-friendly, but they’re also economical, getting great fuel economy. Most car manufacturers have edged into the green industry with their own eco-friendly cars, and although they’re still relatively new to the automotive industry, they have good selection of desirable features. Here are 5 technologies that make green cars even safer.

1. All-Electric

All-electric cars are appealing for a number of reasons. First, car owners charge their vehicles instead of refueling. This can make the upfront cost of the car a little higher, since some households need the manufacturer to install a charging station in their home. However, this cost often pays itself in dividends because it’s cheaper to charge a car every once in awhile than it is to refuel it every week or two.

Additionally, all-electric cars are safer since they don’t contain large quantities of flammable material like gasoline, that can explode in a bad accident.

2. Self-Driving/Semi-Autonomous

Semi-autonomous or self-driving cars are still fairly new on the market, but these cars are smart enough to drive without human input. They can detect their surroundings as well as sense the environment. While the current models can encounter trouble with inclement weather like snow or slick roads from rain, they have no problems with normal road conditions, no matter the time of day.

Self-driving cars decrease the risk of accidents while simultaneously increasing customer satisfaction. People who can’t drive, like children and the elderly can still get around, while those who have driver’s licenses can do other tasks instead of driving—they’re more like a passenger.

3. Anti-Crash Technology

Anti-crash technology lowers the risk of rear-ends and other head-on collisions. Cars that have this software programmed in them are able to detect obstacles ahead, and alert the driver of the vehicle. If the driver doesn’t break in time, or doesn’t break hard enough, these smart cars will break the car for the driver, preventing a collision. While anti-crash technology won’t stop any and all accidents on the road, it definitely reduces the chances of you causing an accident.

4. Hydrogen Fuel

Cars that run on hydrogen fuel cells have already hit the market as a green car alternative to electric vehicles. While some say hydrogen is inefficient, it’s just as safe for drivers and the environment as their electric counterparts, and about the same price.

5. Zero Emissions

One of the key benefits of green cars is how much safer they are to the environment. You don’t have to be a tree-hugger or environmentalist to try to lower your emissions. Manufacturers over the years have been striving to reduce the emissions of the cars produced. Zero emission cars are the result. These cars don’t emit any exhaust gas, which means that you don’t have to worry about harmful pollutants—either for yourself or the environment.

Even if you haven’t made it your mission to save the environment, it shouldn’t be hard to see that eco-friendly cars are good cars to drive. The above technologies are only some of the perks with these cars. Why not drive something safe, while potentially getting a tax credit at the same time?
