Proponents of algae biofuels have stressed its low environmental impact, reduced greenhouse gas emissions, reduced dependence on foreign oil, and utilization of marginal lands. However, a recent report from the U.S. National Research Council has found that algae biofuels cannot currently be produced on a large scale without using unsustainable amounts of energy, water, and fertilizer – exactly the kinds of impacts algae biofuel production was intended to avoid. Notwithstanding this, the report’s authors do not write off the technology. Jen Stutsman of the Department of Energy said in a statement “[The] report outlines the need for continued research and… [more]
View InsightHistorically, widespread uptake of renewable energy has been limited by relatively high costs as compared to traditional energy sources. A 2011 IEA report argued that “renewable energy … is becoming cost-competitive in an increasingly broad range of circumstances, in some cases providing investment opportunities without the need for specific economic support.” Several recent trends, and recently announced business ventures, seem to support the IEA’s finding that some renewable energy sources are approaching cost-competitiveness. Prices for distributed solar have plummeted recently – due largely to economies of scale, government support and policy-driven demand – leading in 2011 to a record 1,855… [more]
View InsightAddressing high gasoline prices at a February 23 speech in Miami, President Obama made a case for continued investment in fuel economy and alternative fuel sources like algal biofuels and natural gas. The U.S. cannot drill its way out of high gas prices, he said, adding that anybody who says otherwise “doesn’t know what they’re talking about or just isn’t telling you the truth.” [Fox News] “It’s the easiest thing in the world to make phony election-year promises about lower gas prices,” Obama said. “What’s harder is to make a serious, sustained commitment to tackle a problem that may not… [more]
