Environmental Impact "Carbon dioxide has to be pumped into the ponds, and there is a high risk of contamination" http://science.howstuffworks.com/environmental/green-science/algae-biodiesel4.htm "Biodiesel increase the emission of nitrogen oxide which is the main reason of fog creation" http://www.tcbiodiesel.com/pros-and-cons-of-using-biodiesel/ " Biodiesel increase the emission of nitrogen oxide which is the main reason of fog creation." http://www.tcbiodiesel.com/pros-and-cons-of-using-biodiesel/ Cons of open pond algae biofuels growing method: "But then you have some shortfalls. For example, you might decide to grow a certain type of algae but after some time – maybe one week - you may end up with a different type in the pond because there has been contamination from the outside. And it works both ways, meaning there can also be contamination from the open pond to the outside world." http://www.euractiv.com/en/innovation/eaba-promises-challenges-algae-biofuels/article-184482 Producing algae biofuel requires too much energy "Leave the algae alone". Low-tech Magazine. 4 Apr. 2008 - "There are very detailed figures on the amount of energy that will come out of the process, yet it is very hard to find any information on the energy and resources needed to make this energy output possible" http://debatepedia.idebate.org/en/index.php/Debate:_Algae_biofuel#What_are_the_pros_and_cons_of_ algae_biofuel.3F Energy-intensive production of algae biofuel emits greenhouse gases Elisabeth Rosenthal. "Biofuels Deemed a Greenhouse Threat". NY Times. 8 Feb. 2008 - "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. .." http://debatepedia.idebate.org/en/index.php/Debate:_Algae_biofuel#What_are_the_pros_and_cons_of_ algae_biofuel.3F Algae biofuel distracts from better ways of reducing emissions Douglas Parr, chief scientific advisor for Greenpeace UK. - "our main worry is that it comes as a distraction from the fact that aviation has got to do plenty of things aside from algae research in order to become truly sustainable."[1] http://debatepedia.idebate.org/en/index.php/Debate:_Algae_biofuel#What_are_the_pros_and_cons_of_ algae_biofuel.3F Indusrial algae depends on dense C02 from coal "Algae biofuel mania". Stockhouse. 11 June 2008 - "Algae can obtain carbon from atmospheric carbon dioxide, but the amounts present are insufficient to promote rapid growth. That requires something like smokestack effluents containing more than 10% CO2, and in fact some of the earliest attempts to grow algae as a fuel source were predicated upon the development of pervasive industrial carbon dioxide capture. That's not happening, and unless it does, real mass production of algal biofuel is scarcely
