Bugs that excrete oil?

19Jun08

It was widely reported that LS9, a startup company in Silicon Valley, claims to have genetically modified E.coli to excrete crude oil, and they further claim the process is carbon negative:

LS9’s bugs are single-cell organisms, each a fraction of a billionth the size of an ant. They start out as industrial yeast or nonpathogenic strains of E. coli, but LS9 modifies them by custom-de-signing their DNA.

Because crude oil (which can be refined into other products, such as petroleum or jet fuel) is only a few molecular stages removed from the fatty acids normally excreted by yeast or E. coli during fermentation, it does not take much fiddling to get the desired result.

The company claims that this “Oil 2.0” will not only be renewable but also carbon negative – meaning that the carbon it emits will be less than that sucked from the atmosphere by the raw materials from which it is made.

The company indicated that they do not intend to use corn as a feedstock, they are instead looking at woodchips and wheat stock, among other things.

The catch here is that their technique does not exactly scale well:

The closest that LS9 has come to mass production is a 1,000-litre fermenting machine, which looks like a large stainless-steel jar, next to a wardrobe-sized computer connected by a tangle of cables and tubes. It has not yet been plugged in. The machine produces the equivalent of one barrel a week and takes up 40 sq ft of floor space.

However, to substitute America’s weekly oil consumption of 143 million barrels, you would need a facility that covered about 205 square miles, an area roughly the size of Chicago.

Books page, Ecology of Commerce

16Jun08

I have added a new Books page, and I’m opening the floor with an excellent book by Paul Hawken, The Ecology of Commerce. You can read a full review on the Books page, but here is one from the Editor-In-Chief of Inc. magazine, that does a better job:

This book, like the vision of capitalism it describes, is gentle, healing, restorative, and quietly eloquent. It will not make you richer, smarter, or more charismatic. It will merely challenge you to reexamine everything you believe about business as it is currently practiced, how we create meaning in our lives, and the fabric of the legacy we are weaving for our children. The Ecology of Commerce is nothing less than an economic and cultural masterpiece

I’ll also add a Films page soon, with reviews and links to relevant documentaries and movies.

Battery shortage triggers hybrid gridlock

10Jun08

Carmakers in the US are currently scrambling to meet the demand for hybrids and smaller, fuel efficient vehicles, as gas prices continue to surge.

Trucks and sport utility vehicles accounted for 47% of Ford’s sales as recently as February but only 34% in May, as consumers opted for compact and subcompact passenger cars. General Motors is adding a third shift at a two assembly plants to meet the rising demand for smaller cars even as it prepares to close four truck plants and puts its entire Hummer operation under review for a possible sale.

About 20% of all Toyota Camrys sold in the U.S. are now hybrids, making them more popular than models equipped with a V6 engine. (Meanwhile, Toyota is sitting on 100-day supply of unsold pickup trucks.)

This is excellent news, but there’s a problem currently hindering this shift in demand: an acute shortage of nickel-metal-hydride batteries. GM and Toyota and scrambling to get their hands on enough batteries, but a new plant to produce them can only come online as early as 2010. TIME even made a direct reference to the documentary film Who Killed the Electric Car?, pointing out that GM aims to purchase the battery subsidiary of Energy Conversion Devices to provide better access to batteries, while these batteries are identical to those GM refused to put into its electric cars in the 1990s (shown in the film).

Ford is facing similar woes:

[Ford] simply cannot get enough of the batteries to keep up with the demand for its Ford Escape and Mercury Mariner hybrid models, says spokesman George Pipas. Ford currently has access to only 24,000 of the special batteries under a contract it signed years ago, he says. “The supply of batteries is capped.”

Car makers continue to jump on the hybrid bandwagon: GM aims to have 8 hybrids on the road by the end of 2008, whereas Honda estimates it will sell 200′000 units per year of its new small petrol-electric hybrid, of which 100′000 units are destined for North America.

GM kills gas guzzler factories

10Jun08

General Motors made international news recently by closing four of its truck and SUV plants across the US, Canada and Mexico, as part of a rapid move to embrace the demand for smaller vehicles in the US.

The world’s largest carmaker said it was making the moves “to aggressively respond to growing demand for fuel-efficient vehicles and to economic and market challenges in North America”.

With fuel prices soaring, GM is considering to sell its Hummer brand, and has already approved a small new Chev model and the Chevy Volt electric vehicle.

Since GM has lost $51 billion over the past 3 years and saw its stock plummet by 60% since October 2007, some investors argue that it’s too little, too late: it would’ve been sensible to sell the Hummer brand long ago:

If they were looking to sell the Hummer brand, the more sensible thing would have been to do it three years ago, they’re not going to get anything for it. Just in terms of timing, it’s a very poor example.

TIME: The War on Global Warming

09Jun08

TIME Magazine has an interesting piece in its April 28 issue where it equates the energy crisis facing the US with a war like any other. They compare it to the Great Depression, the construction of the railroads, the space race, the fight against polio, and so forth. If the US stood up to the those immense challenges, what makes the energy crisis any different? For one thing, this challenge is much harder to overcome. A major problem in the current mix of affairs is that there’s little consensus on how they should approach the crisis, but, as TIME points out, there are a handful of common elements to forthcoming plans which everyone seems to agree upon:

1. Carbon cap-and-trade

We pointed out earlier that Obama suggested a cap-and-trade scheme to deal with carbon emissions. TIME says this is the most important part of a likely blueprint to deal with the crisis.

As long as the sky is free, renewable energy will never beat fossil fuels. But put a price on carbon, and suddenly the alternatives look a lot better. The most feasible way to do this is through a cap-and-trade system that sets ceilings for carbon output and lets companies that come in under the limit sell credits to those that don’t, allowing them to keep polluting—a little. The effect is that overall carbon levels fall, and there is even money to be made by being greener than the next guy. That drives investment and research dollars into renewable energy and efficiency.

The bill that is seen as the best candidate for the job is known as the Lieberman-Warner bill, which mandates a return to 2005 levels of emissions by 2012, followed by a further reduction of 70% below 2005 levels by 2050. Naturally, a clean environment comes at a cost, and one study estimated that this bill would cost the US 4 million jobs by 2030. On the other hand, a study by the EPA predicts that Lieberman-Warner will only curb GDP growth by 1% between 2010 and 2030, not taking into account its possible economic benefits. Since utility companies will be forced to jack their prices following a cap-and-trade system, one green entrepreneur, Peter Barnes, recommends a cap-and-dividend system which will return some of the revenue to consumers in the form of flat rebates.

Unfortunately, after the TIME article came out, Lieberman-Warner was blocked in the US Congress. Lawmakers indicated that they will only make a next attempt once the country has a new president - a promising plan seeing as both John McCain and Barack Obama indicated they would have supported the bill had they been able to attend the vote.

2. Efficiency surge - cutting waste

A study by McKinsley Global Institute found that the US will be able to cut its energy use by at least 50% by 2020 using existing efficiency improvements. A name that is almost always cited is that of Amory Lovins of the Rocky Mountains Institute, one of the leaders in efficiency research and activism. Furthermore, McKinsley estimates that with $170 billion of investment each year in ventures such as green buildings and more environmentally friendly cars, an additional $900 billion can be saved each year by 2020.

Whereas the US has reluctantly jumped on the bandwagon for better fuel economy, countries like Japan have much more effective ways of dealing with this: its Top Runner program takes the vehicle with the best efficiency in the market, and sets its performance as the industry standard. TIME suggests that such a scheme should be applied to architecture, which would be especially effective since half of US energy use is channeled through its buildings.

3. Invest in renewable energy ventures

Admittedly the hardest part in any plan is weaning the nation from carbon. Fortunately, investment in green technology, especially in Silicon Valley, is booming: $5.18 billion in 2007, up 44% from 2006. The Federal Government budgets $5 billion per year for tax cuts and research into renewables and efficiency, but there is much room for improvement: the federal budget for 2008 was $2.9 trillion, and the Iraq war takes $12 billion per month on its own.

On top of this, the Democrats suggested a plan to eliminate $18 billion in tax breaks for the oil industry, using the money for research instead. As John Berger, CEO of Standard Renewable Energy puts it,

How can the oil industry need a dollar in the days of $100 crude oil?

Setting the example - California

California is the US leader in many areas related to mitigating climate change. In 2006 Governor Arnold Schwarzenegger signed the most drastic carbon reduction bill in all of the US, known as law AB 32, which requires attaining 1990 levels of greenhouse emission levels by 2020 (25% reduction). A study by UC Berkeley found that this would augment the state’s economy with 17′000 jobs and a $60 billion GDP boost by 2020 as it sparks innovation, arguably proving the critics of such regulation policies wrong. It is, however, imperative that the US implement a federal (nationwide) policy, since there is the risk that some businesses might flee to adjacent states to escape regulation.

Ever since California has introduced a variable-pricing plan for home energy use, which makes it easier to save energy, demand has already fallen by 13%. California’s per capita energy use has remained constant for 30 years, whereas the average per-capita energy use in the US rose by 50% in the same period.

The utility PG&E estimated that overall, California’s policies have eliminated the need for approximately 24 power plants over the last 30 years.

Epilogue

If the requirement for massive political will is ever met, the outcome of the plan outlined by TIME is anyone’s guess, but it could very well cause the breakthrough the world has been waiting for:

If we took all the steps outlined here—a national cap-and-trade system with teeth, coupled with tougher energy-efficiency mandates and significant new public and private investment in green technologies—where would that get us? We’d be a little poorer—a sustained battle against climate change will hit our wallets hard, absorbing perhaps 2% to 3% of gdp a year for some time, according to energy expert Henry Lee at Harvard’s Kennedy School of Government, though unchecked warming could end global prosperity. But think of it as an investment: that money, if matched by action internationally, can reduce emissions radically over the next half-century, contain warming and lead us to a postcarbon world.

In the light of the current economic woes, this presents a bright beacon of opportunity:

The U.S. has enjoyed an awfully good run since the middle of the 20th century, a sudden ascendancy that no nation before or since has matched. We could give it up in the early years of the 21st, or we could recognize—as we have before—when a leader is needed and step into that breach ourselves.

35mpg - Source of Opportunity

27Jan08

TreeHugger has compiled some facts related to the positive effects of the new 35mpg mileage requirements introduced by the US. The numbers are quite impressive, and illustrate that many Americans may easily overlook the beneficial effects of such initiatives for their country as a whole, as their only concern is their own immediate comfort. I can picture many a Ford F250 or GMC Yukon owner horrified by the idea of driving a small, fuel-efficient car.

241,000 – the number of additional jobs create nationwide, by 2020, that would result from requiring automakers to meet a fleetwide average of 35 miles per gallon (MPG) by 2018.

23,900 – the increase in jobs in the automotive sector alone that would result from the above action.

$37 billion – the amount of money consumers would save, in 2020 alone, from the increased MPG requirements.

1.6 million — the amount of oil, in barrels per day, that the US would save, by 2020, by enacting such action.


Did you know?

Varese, a town in Northern Italy, runs on 100% renewable power. The town uses a mix of wind, solar and small-scale hydropower. The town has reaped benefits from the energy network through added jobs, and an additional 350,000 euros [US $514,000] in revenues that are handed over to the council each year.
