Scientists have created a genetically engineered microbe that turns the algae into low-carbon biofuel, but must make the technique commercially viable
The ancient art of seaweed farming could provide a solution to a 21st-century energy dilemma, with the creation of a genetically engineered microbe that turns the algae into low-carbon biofuel, scientists said on Thursday.
This was supposed to be a big year for energy-related technology.
It was supposed to mark the ascendance of the electric car as the first full year of sales for GM’s Volt and Nissan’s Leaf, which represent the leading edge of electric vehicles planned by major automakers. But GM fell far short of its sales goals for the year, no doubt plagued by high costs due to expensive batteries. And the company ended the year under a cloud of smoke as the Volt’s battery pack caught on fire after safety testing.
It was the year by which advanced-biofuels companies were supposed to be producing 250 million gallons of fuels from grass and wood chips to meet a U.S. federal mandate. But the EPA had to waive the mandate, decreasing the goal to just 6.6 million gallons, because no large advanced-biofuels plants were up and running. The year ended with the demise of one of the first advanced-biofuels companies, Range Fuels, which shut down operations and was forced to auction off assets.
Even as Congressional leaders continue to drag their feet on clean energy and many states keep renewables-related legislation on the back burner because of the still-sluggish economy, the U.S. military continues to invest money and research into green energy.
The Pew Project on National Security, Energy and Climate said in a report released on Wednesday that U.S. Department of Defense (DoD) spending on alternative energy skyrocketed 300% between 2006 and 2009, from $400 million to $1.2 billion, and that figure is expected to top $10 billion annually by the year 2030.
According to a new report from the U.S. Energy Information Administration (EIA), the consumption of engery from renewable sources recently topped both the current and the historical consumption levels for nuclear energy. The shift was immediately caused by nuclear outages that coincided with the high-water season for hydropower generation.
But there’s a long-term upward trend in renewables which can be seen here, too, thanks to the increased consumption of biofuels and wind capacity additions.
