The alt fuels distraction
$this->bbcode_second_pass_quote('', 'I')n the next 50 years, give or take, those of us in the United States will face two challenges. We must wean ourselves off of oil and we must cut our carbon-dioxide emissions by around 60 percent. Either would be difficult in isolation; together, well ... imagine patting your head and rubbing your belly at the same time, only with trillions of dollars and millions of lives at stake. And with one arm tied behind your back.
What's the best way to meet these challenges? If you were the proverbial Martian, visiting our planet to dispassionately assess our options, what would you find most promising?
And if our Martian wanted to get a little bit more ambitious, he might emphasize these broader policy and technological initiatives:
• Quit subsidizing fossil-fuel industries. Period.
• Impose a gas or carbon tax. It would put uniform pressure on the market to reduce oil consumption, without favoring any particular alternative. (The impact on low-income Americans could be offset with reduced payroll taxes.)
• Encourage density by reversing land-use policies at all levels of government that subsidize road-building and sprawl at the expense of compact, walkable, mixed-use communities served by effective public transportation.
• Drop perverse agricultural subsidies that overwhelmingly favor petro-heavy industrial agriculture and long-distance food transport at the expense of organic farms and local food systems.
• Scrap electricity-market regulations that virtually mandate centralized power production at large, inefficient plants (by some estimates, up to two-thirds of energy is wasted en route to end users); instead, encourage decentralized production from small-scale, site-appropriate sources.
