00:04:22 Ethanol: Energy Balance and Greenhouse Gas Emissions
Suffisance des terres pour la production d’éthanol : Le rapport du NRDC estime que 114 millions d’acres suffisent pour satisfaire les besoins en éthanol. D’autres, comme Jim Woolsey, estiment que seulement 30 millions d’acres pourraient suffire. Vinod Khosla estime qu’entre 40 et 60 millions d’acres pourraient répondre aux besoins.
Rendement des plantes à fibres en termes énergétiques : Les plantes à fibres comme le miscanthus pourraient produire de 10 à 30 tonnes par hectare, selon les conditions. Elles n’ont pas besoin d’être replantées chaque année, ce qui réduit les besoins en main-d’œuvre. Elles nécessitent peu d’engrais et d’eau.
Comparaison avec l’Arabie saoudite en termes de production d’énergie : Si les États-Unis parvenaient à produire un rendement suffisant à partir de plantes à fibres, ils pourraient remplacer l’Iran et l’Arabie saoudite en termes de production d’énergie.
L’utilisation des terres agricoles pour la production d’éthanol : Les États-Unis possèdent des terres agricoles sous-utilisées qui pourraient être utilisées pour la production d’éthanol à partir de plantes à fibres.
La pertinence de la balance énergétique : La balance énergétique est une question secondaire. Les émissions de carbone par mile et la sécurité énergétique sont plus importantes.
Émissions de gaz à effet de serre et utilisation de combustibles fossiles : L’éthanol, même le bioéthanol, réduit considérablement l’utilisation de combustibles fossiles. Il entraîne également des réductions modérées des émissions de gaz à effet de serre.
Exemple de réussite : E3 Biofuels : E3 Biofuels a mis en place une usine de production d’éthanol à partir de plantes à fibres dans le Nebraska. Ils ont atteint une efficacité énergétique comparable à celle de l’éthanol cellulosique. Ils ont aussi obtenu des réductions similaires de gaz à effet de serre grâce à un système de ferme intégré.
00:11:47 Ethanol: A Viable Path to Energy Independence
Ethanol: Ethanol has been receiving strict emission standards in California. Ethanol provides a trajectory for cellulosic economies by increasing ethanol yield from 400-500 gallons per acre to potentially six times that amount in the next 25 years. A shift to cellulosic ethanol would mean a 25% reduction in electricity demand, less ethanol requirement, and an easier replacement with improvements in fuel efficiency. Ethanol and hybrid technologies are compatible and likely to coexist.
Cellulose: Despite skepticism, cellulosic ethanol is an emerging technology using a vial of ethanol produced from standard wood chips through a production, not experimental, process. There are companies producing five times the amount of ethanol yield per acre using algae or synthetic bio-refining techniques. The possibility of these technologies is reinforced by the consistent increase in ethanol prices per hectare in Brazil over the past 30 years. In the US too, technologies are progressing, with cellulosic materials showing higher yield potential.
Economic Viability: The announcement by the previous energy administration on oil prices has made the above possibilities viable, as long-term oil prices are expected to reach around $40 per barrel.
00:17:54 Strategies for Promoting Biofuel Adoption in the United States
Key Points: Khosla presents four distinct approaches that could viably replace oil. He emphasizes that risk assessment and comparison of different energy sources depend on one’s political affiliation, with environmentalists prioritizing environmental costs and neoconservatives focusing on energy security and independence. Biological energy is identified as the lowest-cost and lowest-risk option, highlighting the need for a Darwinian IQ test in the next decade. Khosla proposes policy recommendations that involve less government funding, eliminating subsidies, and implementing certain mandates.
Ethanol Policies: Khosla suggests a California bill mandating that almost all cars be capable of using ethanol and oxygenated fuels. He recommends providing a $35 incentive for car manufacturers to include this capability in new vehicles. Khosla proposes expanding E85 fuel pumps at gas stations to ensure widespread availability. He advocates for reducing the ethanol subsidy in a strategic manner to provide counter-cyclical insurance against oil price manipulation.
Ethanol’s Potential: Khosla presents a graph depicting the potential replacement of gasoline with ethanol, showing significant room for expansion. He acknowledges the possibility of underestimating the replacement rate by a factor of 2 and still considers it a remarkable success.
Addressing Oil Price Manipulation: Khosla stresses the importance of sending a clear signal to oil companies that manipulating oil prices will not lead to the exploitation of ethanol. He proposes a variable ethanol subsidy that adjusts based on oil prices, providing assurance against price fluctuations.
Conclusion: Khosla emphasizes the significance of taking proactive steps to transition away from oil dependence and highlights the potential of biological energy, particularly ethanol, as a viable alternative. His policy recommendations aim to promote the adoption of ethanol and mitigate the risks associated with oil price manipulation.
00:23:06 Ethanol: A Viable Alternative Fuel for the Present and Future
BioHall Trajectory: Vinod Khosla believes that while ethanol is the current solution, it will be replaced by other technologies over time. He coined the term “Biohall Trajectory” to describe this transition. The idea is that all new energy technologies will start with ethanol as their base and improve from there.
Biopower 95: Saab’s Biopower 95 was the most expensive GM model in Sweden due to its ability to run on E85 fuel.
Ethanol vs Gasoline: One advantage of ethanol is that it provides more power than gasoline. The penalty for starting a gasoline engine on ethanol is reduced with a higher compression ratio.
Ethanol Myths: There are many myths surrounding ethanol, which are addressed in Khosla’s second paper. While some studies show a positive energy balance for ethanol, only studies showing a negative balance are often cited in the media. This is due to the practice of journalists presenting both sides of an issue, leading to inaccuracies.
Ethanol Subsidies vs Oil Subsidies: Ethanol subsidies are often criticized, but Khosla points out that gas subsidies are significantly higher. Direct and indirect gas subsidies have been estimated in dollars per gallon, making it not a free market.
Investment Horizons: Investors require incremental returns over periods of 2 to 3 years, not long-term investments with uncertain returns. Hydrogen, for example, may have a long-term potential but lacks incremental revenue opportunities.
Ethanol as the Starting Point: Khosla believes that ethanol is the right answer for today. As people explore ethanol’s underlying chemistry, they will find new chemistries with higher energy, improved power, and lower production costs.
Ethanol Price at Wal-Mart: Khosla’s vision is to sell ethanol at $1.99 per gallon at every Wal-Mart in America. He is willing to sell all the ethanol Wal-Mart needs at a price that allows them to sell it for $1.99 per gallon, given a long-term contract and the ability to build enough capacity.
BioHall Trajectory Worldwide: Khosla explored how ethanol-based biomass flows will progress over time worldwide. He observed that the United States is mostly self-sufficient in this regard, while China and Europe are supplied differently.

Concluding his presentation, Khosla discusses ethanol’s global implications, particularly its role in poverty alleviation. He envisions ethanol-based biomass meeting the energy needs of developing countries, reducing their reliance on imported fossil fuels, and fostering global economic stability. Ethanol has been receiving strict emission standards in California, providing a trajectory for cellulosic economies.
Supplemental Information Integration:
Khosla suggests a comprehensive approach to policy reform for ethanol adoption. He proposes a California bill mandating that almost all cars be capable of using ethanol and oxygenated fuels, along with a $35 incentive for car manufacturers to include this capability in new vehicles. Expanding E85 fuel pumps at gas stations is also recommended to ensure ethanol’s widespread availability. Furthermore, Khosla advocates for reducing the ethanol subsidy in a strategic manner, providing counter-cyclical insurance against oil price manipulation.
Addressing the potential of ethanol, Khosla presents data showing the significant room for replacing gasoline with ethanol. Even if the replacement rate is underestimated by a factor of two, it would still be considered a remarkable success. Khosla emphasizes the importance of sending a clear signal to oil companies that manipulating oil prices will not lead to the exploitation of ethanol. He proposes a variable ethanol subsidy that adjusts based on oil prices, providing assurance against price fluctuations.
In the “BioHall Trajectory,” Khosla envisions a transition from ethanol to more advanced technologies over time. He argues that while ethanol is the current solution, it will eventually be replaced by technologies offering higher energy, improved power, and lower production costs. Dispelling myths about ethanol, he addresses the media’s often one-sided portrayal of ethanol’s energy balance and highlights the significantly higher subsidies for gas compared to ethanol. Khosla’s investment strategies focus on incremental returns, viewing technologies like hydrogen as less appealing due to their long-term and uncertain revenue potentials.
Khosla’s vision includes selling ethanol at $1.99 per gallon at every Wal-Mart in America, under a long-term contract and with sufficient capacity. He believes that exploring ethanol’s underlying chemistry will lead to new and more efficient chemistries, establishing ethanol as the starting point for future energy solutions.
