Sustainability is one of the major topics discussed by different environmental organizations as well as the government of different countries. Most of our natural resources are nearly depleted that is why, finding alternatives derived from renewable resources is a big challenge for all of us. Renewable resources could also address the problem regarding global warming. All of us are aware that most of the pollutants in the atmosphere come from the fossil fuels burned in our car engines. This is why car companies faced a big challenge in converting those environment killing cars to a more environment friendly cars. The first step is adding biodiesel in those petroleum diesels to reduce toxic gas emissions. The next step is total prevention of using the fossil fuels to run our cars.

There are many ways on how to make our cars run without being solely dependent on petroleum diesel and conventional motor gasoline. Hybrid solar powered cars are now developed in different countries. Those cars are using solar panels to get the sufficient amount of energy from the sun to charge its batteries. And at night, the car would be run by gasoline. This car couldn't totally be independent of conventional gasoline but lessens the consumption of it. Another newly developed environment friendly car is the one that could run using electricity. All you have to do is charge you car's battery and it can get you in the place where you want to. It is like filling your tank with fuel, but it is more advisable since using electricity powered car does not require burning of fuels that emits toxic gases. If charging stations are already available, those electric cars could be a hit. A fuel-less vehicle is also developed which runs on combining air and magnets. It will also use batteries to induce magnetic effect and modulate the air and makes a propeller inside the car work inducing mechanical energy that could run the car.

Using biodiesel as additives is now adopted in most of the countries since it is the easiest way and faster way to address the issue on air pollution and global warming. Biodiesel derived from ethyl alcohol and methyl esther extracted from plants and other crops is currently introduced in the market. Since most of the cars have diesel engines, it is more possible to adopt biodiesel as new fuels for your cars. And besides, you will not have more troubles in modifying your engines because biodiesel is compatible for diesel engines. This is why using biodiesel is considered the first step to lessen the use of fossil fuels which are nearly depleted. Promoting this approach or using those biodiesel, the global warming problem could be answered.

It would be better if those environment friendly cars are fully developed and made available in the market sooner. Who would believe that those magnificent cars could run without depending on conventional gasoline? This could be a new approach towards sustainability and this could only be possible if all of us would support these environment friendly methods and projects.
