“biofuels made from waste biomass or from biomass grown on degraded and abandoned agricultural lands planted with perennials incur little or no carbon debt and can offer immediate and sustained GHG advantages”
-University of Minnesota
Ofcourse, burning down forests is not a good idea, but produced well, biofuels are good for the environment. (unfortunately, the “produced well” part is a bit tricky :roll: )
On the chart below: I think it does take into account the energy costs that go into creating/extracting biofuels/oils. What else would it take into account? Not the net production of CO2 from burning the biofuel, because that is 0. (Owkey, quick explanation: CO2 in air = bad, CO2 in soil = good. Plants take CO2 from air and put them in soil = good. Burning fuels takes CO2 from soil and puts them in air = bad. Fossil fuels do only the latter = bad. Biofuels do both = good + bad = 0. )
But I do think the data doesn’t take into account burned forests unfortunately, nor the impact of other chemical elements (also generated by producing regular food) :(
@Cmdr:
And the price of oil is all speculation. People “think” the market is bad because the media’s been telling us the market is “bad” for the past decade. As soon as people realize they were lied too, oil prices (and gold and all the other commodities which are currently insanely too high in value to be supported) will plummet in a Commodity Bubble Burst.
…
I say we’ll see a significant commodity bubble burst in 2009-2010. By significant I’m talking a “correction” market of 20% drop on the top end, up to about a “bear” market of 30-40%.
note: this is quite a lengthy post, summary in the last alinea…
There’s a difference between gold and oil: we need oil, but we don’t need gold (we just like to have it). Imagine tomorrow it would become clear our stocks of food (=product we need) is limited: there won’t be more food EVER. What would happen with the food prices, though there’s enough food to satisfy demands for 40 years? Would they stay the same for about 39 years and then rise insanely, causing wars etc? Or would they, since everyone knows for sure the food will be gone in 40 years, start raising today? (et en plus those other factors mentioned: rapidly growing demand in other countries, food starting to get more difficult to produce…) (note to reader: this is going about oil, not food, because the two things are a bit mixed up in this thread)
And you blame the media, like the american media has anything to do with oil prices in Russia, Iran or the Emirates…
It is true the media can make people believe things that aren’t true, but it has zip influence on the oil market, because people have zip influence on the oil market. The oil market is governed by companies and governments, not consumers. Consumers have to follow the price being given, because they need the oil!
Imagine you’re an oil company. Why would you lower your prices? If you do, everyone will buy your oil, your fields will be depleted in no time, and sure, you’re gonna be rich. But you could have been even richer if you just sold all your oil at the same price as the rest of the world. There’s no worry the oil will grow bad or won’t be bought in the near future, so why lower prices? And there’s no way of producing more, so no other company can flood the market with cheap oil without benefitting you in the long run (there will be less oil for the future, so you can make even more profit then).
If I had the capacity to store a lot of oil for a lot of years, I would immediately do it. The only thing that’s keeping oil prices in check for the moment are alternatives like solar energy or hydrogen fuel, but those are no real competitors to oil in the near future, and it’s not sure in 40 years those techniques will be adequately developed to replace oil. And since those alternatives are no real competitors yet and since it’s not sure they will be on time, the “keeping in check”-part is not that great, as reflected in the oil prices…
Summary: Oil is our only option for the moment, and whatever the price wil be, we will pay it because we need it. This together with the fact that the oil is limited and there are no real alternatives for oil, makes me believe oil companies have no reason to lower the prices significantly in the next few years. As you can see, I don’t believe the media has anything to do with high oil prices.
PS (oil price estimated in €, because the weak $ is making things worse for you guys at the moment)
