Green, Greener, Greenest! Even in the production of biofuel you got companies who are even greener than others. Usually biofuel comes from animals or plants, so how green is biofuel?

In Sweden biomass has passed oil as the top source for energy generation. In 2009 biomass energy production reached 115 TW hours, which represents 32% of all energy consumption. At the same time, oil-based energy production topped at 112 TWh. Next to that, the use of biofuel is expected to increase, while fossil fuel use should further decline in the next couple of years.
We all know that biogas is created using plants as input and out comes the gas. But how does this transition exactly work? Here a short video about the process:
Unfortunately this is a rather short video about the process. To understand it some more you have to view this video here (redirecting you to youtube).

Due to high oil prices and the competing demands between foods and other biofuel sources, such as palm and soybeans, due to the world’s food crisis, interest in biofuel from Algae is higher than ever before. Algae are one of the fastest growing plant species in the world. Some strains of algae can even grow so rapidly that they double in size every day, producing large amounts of lipids (oils).

Aviation is responsible for 12% of CO2 emissions from all transport sources, which is 3% of the total man-made contribution to climate change. To prevent climate change to reach a point of no return, carbon emissions from aviation must also be greatly reduced to near zero emissions. Since the start of aviation, particularly the jet age, aviation has reduced fuel burn, carbon and water vapour emissions by some 70% per passenger kilometre. Airlines are aiming for a further 25% fuel efficiency improvement by the year 2020. They want to achieve this efficiency through technology and operational enhancements.
Production of crops such as maize and palm oil are fuelling poverty and create environmental damage in poor countries, Christian Aid says. According to the charity the huge subsidies and targets in developed countries for the boost of production of fuels from plants are exacerbating environmental and social problems in poor nations.
