What do you think about bio-fuel as a source of renewable energy?
Can Bio Fuel be a reliable source of renewable energy in future?

Why you think so that it isn't a reliable source of renewable energy? Can't we use the wasted bio fuels like take simple example of our daily use(i.e vegetable oil), we can recycle it and use it to produce energy and use that energy for our daily use. There are many restaurants which use excess of oil to deep fry food like KFC, so if we take wasted oil from likewise restaurants and use it to recycle. This is only one example, we can take many examples from our daily life and use these sources to produce electricity. |

Nope, I agree with Sig. The whole idea of "re"newable energy is bust, it's an oxymoron statement like a Everlasting Gobstopper Why so? Could you please mention some reasons? |

The mass energy required for transportation industry etc will not be met with waste. |

Bio fuels are fine in small amounts - like gathering wood for a camp fire. However, they do not scale up too well. The Energy required for creating the bio fuels starts to get higher than the energy obtained. So ethanol from corn and sugar cane works - but the amount of energy put into it is close to what you get out of it. And the tractors and bio fuel plants are run on normal fuels or grid power. Like most so called renewables they do not create sufficient surplus power to build and run themselves. The reason for them does not exist as nobody has shown in the real world that CO2 causes any warming - no evidence at all - none. While there is significant evidence against CO2 causing warming. So I see no reason to go to bio fuels. If you are worried about energy then use Thorium pebble bed or molten salt reactors limitless energy as continuous base load power available to anyone and everyone.

Samijafri, your examples are small scale and (probably) good examples of recycling but I wouldn't hold my breath WRT global road transport/shipping/air transport/agriculture. Still a worthwhile discussion .... |

For me it fails on several fronts.
1. If the government thought of it then commercially its doomed. The centrally planned kiss of death.
2. If its so good why the need for a subsidy.Just buy the stuff if you wan it.
3. The concept of running a car on used fat is fine so long as it does not need to pay its portion of tax's and people treat the project as an unpaid project.
4. If its using land based agriculture it backs out food production or forestry development or even worse it encourages land clearing and the consequent smoke plume killing millions in Asia.

Why so? Could you please mention some reasons? The family used to use used oil, all types, and produced biodiesel which was sold to I think it was UPS or it may have been FedEx trucks. Return on investment was not fantastic and it was a limited market both in terms of production and use. We could only produce so much as we could only acquire so much used oil and there were only so many vehicles that ran on the finished product. It turned out to be a nice hobby. Did I mention it was dirty? But what about the fuel which can be obtained from factories and industries? i guess it's quantity is far enough as compare to others bio mass sources. |

From memory, there are several lessons from history that suggest cutting down trees can lead to the extinction of civilisations.
Not a fan of biofuels as a serious energy source. I'd rather the trees kept doing their job as oxygen generators ..... gasp.
