Better biofuels are a really big deal. That means we can precisely engineer the molecules in the fuel chain and optimize them along the way. So, if all goes well, they're going to have designer bugs in warm vats that are eating and digesting sugars to excrete better biofuels. I guess that's better living through bugs.

Energy legislation in Congress and the focus on energy legislation is first and foremost about creating good jobs. In Florida, where solar and biofuel and wind and so many other areas are important and so many in the private sector continues to pursue these, we need policies that will encourage that.

For the Navy, developing alternatives to fossil fuels isn't just about fighting climate change - though that's an important side benefit. Biofuels will also play a much more practical role in the Navy's fuel mix, boosting our energy security and supporting the U.S. economy.

Bill Gates

The most interesting biofuel efforts avoid using land that's expensive and has high opportunity costs. They do this by getting onto other types of land, or taking advantage of byproducts that aren't used in the food chain today, or by intercropping.

Raul Grijalva

Instead of destroying an area for a paltry amount of oil, we should be increasing fuel standards for automobiles and focusing our efforts on biofuels and other alternatives.

Vinod Khosla

Certain food-based biofuels like biodiesel have always been a bad idea. Others like corn ethanol have served a useful purpose and essentially are obsoleting themselves.

Fatih Birol

We have to use cars much more efficiently. We have to look at alternative technologies of cars such as biofuels or, even more importantly, electric cars.

Turkish Economist

Elon Musk

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

South African Businessman

Michael Shellenberger

The main problem with biofuels - the land required - stems from their low power density.

When most people talk about biofuels, they talk about using oils or grease from plants.

American Scientist

Biofuel is technical and environmental; use it in discussions about sustainable energy and technology.

Context Clarification

Biofuel is different from fossil fuels; it's sustainable and less harmful to the environment.

Not Fossil Fuels

Biofuel is made from recent organic materials, not ancient biological matter like oil.

Living Sources

Biofuel comes from biomass, which includes plant materials and animal waste.

Biomass Origin

Biofuel is renewable, meaning its sources can be regrown or replenished quickly.

Renewable Aspect

Processing and converting biomass into biofuel is complex and involves various technologies.

Conversion Process

 But what's really important here to remember is that it's not all bad. It's not that agriculture's a bad thing. In fact, we completely depend on it. It's not optional. It's not a luxury. It's an absolute necessity. We have to provide food and feed and, yeah, fiber and even biofuels to something like seven billion people

 envelope calculation we love back of envelope calculations you ask a question you write down some numbers and you get yourself an answer it may not be very accurate but it may make you say hmm so here's a question imagine if we said oh yes we can get off fossil fuels we'll use biofuels problem-solve transport we

A reality check on...

 countries as well have these huge problems with maintaining enough energy for their normal life needs finding new fuels but also finding storage for them there's a solution we wanted to find just one matter just one material from which we could produce both so biofuel and a material that will store a biofuel

Turning chicken feathers...

 because our political systems fail. Today, less than two percent of the world's energy consumption derives from advanced, renewable sources such as solar, wind and biofuels, less than two percent, and the reason is purely economic. Coal and natural gas are cheaper

 like fishermen and ships and such things, but hey, we're talking about biofuels, and we know the importance of potentially getting an alternative liquid fuel. Why are we talking about microalgae? Here you see a graph showing you the different types

 Studying the adaptations of extremophiles may hold the key to solving many of Earth's problems. This includes the development of genetically based medications, producing new types of biofuels, and protecting people against radiation exposure.

 So here's a Imagine if we said, "Oh yes, we can get off fossil fuels. We'll use biofuels. Problem solved. Transport ... We don't need oil anymore." Well, what if we grew the biofuels for a road on the grass verge at the edge of the road?

David Mackay: A reality...

 area of this so you'd have to worry about other stakeholders like fishermen and ships and such things but hey we're talking about biofuels and we know the importance of potentially getting an alternative liquid fuel why are we

 But it's a necessary piece for the tail of emissions. And a third priority is aviation biofuels. Now flying over the last several years has become a symbol of a polluting lifestyle, let's say.

 electricity and advanced biofuels. The trucks and planes can realistically use hydrogen or advanced biofuels. The trucks could even use natural gas. But no vehicles will need oil.
