Oil, Biodiesel, and Electric Cars

By Geneva

Which are better for the environment: biodiesel or electric cars?
Biodiesel cars run on renewable energy, not on oil. They are energy efficient, and give out much less emissions than the average car using oil. There is some debate, however, as to whether biodiesel actually gives as much energy as it costs to produce or not. Electric cars, on the other hand, don't give out any emissions at all. They are just as efficient as any other car, but a bit more expensive. In conclusion, biodiesel has many benefits but an electric car is better for the environment.
Is it bad for the environment to have an automobile run on oil?
Of course, almost every car runs on oil, and most people don't have a problem with that in their everyday lives. But most people do not know that if we don't find a good replacement for oil soon, we'll be in trouble. So, the less everyone uses oil, the more oil we'll have to save in the future. Using up lots of oil right now doesn't seem like it will make a difference environmentally, but in the end, it will.
Is the economy affected by cars running on oil?
Oil is becoming more rare as supplies diminish. The price will keep on rising until we have run out of oil and there is no oil left to sell. When that happens, we must have a plan so that we can keep on powering automobiles, planes, and machinery and so we can keep on making clothing, plastic, computers, cars, planes, boats, and almost everything else in the world. If we don't come up with a plan soon, everything that runs on oil will become obsolete.
