Current Developments: Innovative Ideas on How to Make Electric Cars Cost-Efficient Take Shape

It’s easy to knock electric vehicles (EVs): It takes too long to recharge the batteries and there are too few places to do it. And besides, who will pay for all the new recharging stations that would be needed if the cars catch on? The International Energy Agency’s most optimistic scenario puts (pdf) plug-in hybrids or EVs at 15 percent of all cars on the road by 2020; other projections predict a mere 3 percent.

The dubious outlook for EVs has much do to with uncertainty over what role utility companies should play in providing the electricity needed for large fleets of these vehicles. At a recent conference, however, industry analysts put several options on the table.

Wood Biofuel Could Be a Competitive Industry by 2020

From ScienceDaily

Fuel made from wood could become a competitive commercial alternative to fuel made from corn by 2020 if the wood biofuel industry is supported, according to a new University of British Columbia study.

Corn ethanol is currently blended with gasoline to satisfy government-mandated targets to include renewable content in transportation fuel. Compared to corn, wood-based biofuel is considered more sustainable but is not currently produced in large commercial quantities in Canada and the United States because the costs are too great.

The study, published in the most recent issue of the journal Biofuels Bioproducts & Biorefining, identifies several opportunities for reducing these costs. Researchers in UBC’s Faculty of Forestry found that large-scale commercial production of wood-based ethanol, also known as cellulosic ethanol, will reduce capital and operation costs and assist in achieving the improvements necessary for wood-based ethanol to compete, without government support.

Why Firms Go Green

From the Economist

SHORTLY before the 2009 UN climate summit in Copenhagen, many companies got into green. The summit was expected to lead to new regulations restricting greenhouse-gas emissions. Dozens of chief executives came to see history being made and to be seen on the right side of it. But Copenhagen was a flop. Most firms turned their thoughts elsewhere. Only four bosses showed up at the next annual climate meet, in Cancún. Few are expected at this year’s bash, which begins in Durban on November 28th.

Alas, that represents a realistic assessment of the Durban summit’s chances of delivering anything like the long-term certainty that businesses crave. Of 300 bosses of big global firms recently quizzed by Ernst & Young, 83% said they wanted to see a legally binding multilateral deal struck in Durban to update the ailing Kyoto protocol and help to put a price on carbon emissions. But only 18% expect this to happen. The absence of a clear climate policy helps explain why, for example, investment in British clean technology fell from around $11 billion in 2009 to $3 billion last year. It would also suggest that any firm factoring a steep carbon price into its plans—as Shell does, assuming a notional price of $40 a tonne—should quietly lower it.

Americans Using More Fossil Fuels

From ScienceDaily

American energy use went back up in 2010 compared to 2009, when consumption was at a 12-year low. The United States used more fossil fuels in 2010 than in 2009, while renewable electricity remained approximately constant, with an increase in wind power offset by a modest decline in hydroelectricity. There also was a significant increase in biomass consumption, according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory.

Wind power jumped from .70 quadrillion BTU, or quads, in 2009 to .92 quads in 2010. (A BTU or British Thermal Unit is a unit of measurement for energy and is equivalent to about 1.055 kilojoules). Most of that energy is tied directly to electricity generation and thus helps decrease the use of coal for electricity production. Biomass energy consumption rose from 3.88 quads to 4.29 quads. That increase was driven by ethanol use as a transportation fuel and a feedstock for industrial production. (The apparent decline in geothermal energy use is due to an accounting change by the Energy Information Administration.)
