[ad#125-right]We recently posted an article about global warming showing the average temperatures in 2008 across the globe. Whether or not we agree that this was caused by human interference in the atmosphere, it is clear that some things we do can help or hinder the process of attempting to stabilize the climate. Replacing fossil fuels with biofuels sounds like a good idea to calm down the Peak Oil folks, but it will just heat up the debate in the Climate Change camp…
Almost all biofuels used today cause more greenhouse gas emissions than conventional fuels if the full emissions costs of producing these “green” fuels are taken into account
The exception may be some of the efforts to produce fuel from algae, which is currently quite expensive to produce…
As part of the photosynthesis process algae produce oil and can generate 15 times more oil per acre than other plants used for biofuels, such as corn and switchgrass. Algae can grow in salt water, freshwater or even contaminated water, at sea or in ponds, and on land not suitable for food production.
On top of those advantages, algae — at least in theory — should grow even better when fed extra carbon dioxide (the main greenhouse gas) and organic material like sewage. If so, algae could produce biofuel while cleaning up other problems.
Little known fact: the farming of algae is called Algaculture.
The main problem is that we might be able to produce it, but doesn’t it still release greenhouse gases into the atmosphere ? Isn’t that part of what we are trying to avoid?
