Hybrids come in many forms. There's the diesel engine retrofitted to use vegetable oil a.k.a
biofuel or biodiesel. SVO meaning straight vegetable oil and WVO meaning waste vegetable oil. In my opinion WVO being the most eco-friendly because it's not virgin oil like SVO. I whole believe all things should be reused before beind discarded. With WVO the oil was formly used at say a fast food restaurant to fry your food. Hence the joke that biodiesel cars smell like french fries. WVO is easier for the general public to use at home, thus making the conversion to this cleaner fuel a no-brainer. (Yes, in a pinch you can still use regular old diesel fuel if you need to, but who'd want to with the prices the way they are these days?)
Another hybrid we are all familiar with is the electric/gasoline autos such as the Honda Civic or the Toyota Prius. These use an extra battery to help support the engine with electric power to save on gas, getting around 50mpg, on average for the smaller cars and 35mpg for larger hybrids. Another great eco-friendly feature for the gas/electric hybrid is that the engine shuts off when you are at a stop, thus reducing emissions. You do
not need to plug in these cars, thus reducing our pull from the grid.
On the horizon, cars you plug in and cars that use hydrogen fuel.
What makes a plug in car eco-friendly? In my opinion, not much if you are not using solar to recharge the battery. When you plug it in you are plugging into the grid, which is usually mostly powered by coal burning or petroleum using plants. Though the rise of solar and wind power generated plants is upon us, it's not quit the norm. So plugging into the grid isn't very eco-friendly, yet. If the market for plug in cars surges, we need to also promote the heck out of solar power for our home to recharge that car!
So are all these new hybrids and concept cars really eco-friendly? The answer might surprise you!
NO. "NO?" you ask. That's right. Here's why
most of these cars are not so eco-friendly. If you have a car that is in good condition, nothing wrong with it, and you are trading it in just for the sole purpose of up-grading to a hybrid or plug in, you are doing more damage than good. Buying an eco-friendly car w/out the true need of getting rid of your old car, is well, not so eco-friendly. This is greedy consumerism. It's only truly eco-friendly if say, you don't have a car and you get a hybrid, or your old car has finally bit the dust. I'm not encouraging driving your car off a cliff to save your conscience of buying a hybrid.
The true eco-friendly car from my list are the biodiesel cars, because you are not getting rid of your old car, you are converting you diesel engine to run more clean.
If we could get major car companies to convert the cars we have, rather than come out w/ new models all together, then we would have a real Eco-Friendly car.
