Weeds are the answer.
That's one point made by Arjun Makhijani from the Institute for Energy and Environmental Research. He was interviewed today in the second half of KUOW's show called The Conversation. The Conversation, May 13 2008, second half.
Aquatic weeds basking in sunlight and growing in ponds of wastewater could yield up to 10,000 gallons of fuel per acre. Less liability and cost than nuclear power. Pumping wastewater from Los Angeles to arid spaces not currently used for crop production could hold great potential. Ponds with certain types of aquatic plants can produce a lot of fuel, I guess. This type of solution could power our future along with things like windmills and solar energy.
Still, I found myself disagreeing with one point Makhijani made in the interview.
When ask about things like changing lifestyles, reducing automobile dependency and consumption, he seems to feel that people will not cut back on driving. He doesn't think we can wait until we settle the values argument between cutting back consumption and "full speed ahead" that is going on in society.
Well, I don't think it's a case of settling a values argument. Our diverse society will never settle an argument of values as if it is a "one size fits all" proposition. Even if a percentage people cut back on driving it would make a big difference. This would not even have to be the majority.
It isn't necessarily a case of settling some values argument once and for all. It might be just a case of getting a percentage of society to do more bicycling and public transit.
In the long run, it did sound like he would favor lower consumption. He even mentioned Gandhi's famous line about being the change you wish to see in this world.
Still, it seems like Makhijani would feel that plug-in hybrid cars fueled by clean energy sources are a more practical short term solution than, say bicycling to work.
Farther down the road, there's some exciting electric vehicles on the way. He talked about a pickup truck that can go from 0 to 60 in 10 seconds and a sports car that can do it in 4 seconds.
Anyone have $100,000 laying around for something like a Tesla Vehicle?
Yes, the price of new technologies comes down over time, but gas and diesel prices are going up faster. For some people, bicycles and public transit will be more practical solutions in the short term. This is not waiting till society settles, once and for all, a values argument between speeding up and slowing down.
For a significant segment of society, lifestyle change is likely to be the only way. This is especially true as we go through the transition from a fossil fuel economy to cleaner energy technology.
In the short run, it's still going to get a lot more expensive to drive. A lot more expensive until we get those weed ponds, windmills and solar panels working.
It's especially going to get more expensive to drive if we start imposing things like carbon allowances on old style energy producers.
Making the fossil fuel burning enterprises, such as power plants and trucking fleets pay more for a nationally set up system of carbon allowances seems like a good idea. This was also was brought up in the interview. It would help level the playing field so clean energy can compete and develop.
Still, things like carbon allowances would likely add even more to the cost of living in the short run. Lots of people are trying to figure out how they can afford the commute to work.
For a large percent of the population, the bicycle and public transit will have to be the way to work as we make our way through this transition to cleaner and more abundant energy technology. In that process, many will discover that bicycling helps a lot of other things, such as one's health.
So the bicycle and "low energy consumption" needs more respect, even as technology promises an abundant future of clean energy.
PS. I saw a Youtube video on Tesla Roadster. Glad it's got airbags.
