Electric vehicles aren’t “zero-emissions” as advertised. Sure, EVs may have no tailpipe emissions, but when an EV plugs in, where does the energy come from? The fact is, almost 50 percent of our nation’s electricity is produced by coal. According to one new study, half of an EV’s lifecycle greenhouse gas emissions are produced during the manufacturing and shipping phase.

• Alternative vehicle fuels aren’t just better for the environment, they’re better for your health. In some states, vehicle emissions constitute the largest source of air pollution like smog and ozone, which can lead to respiratory and other health issues. That’s why the American Lung Association promotes alternative fuel use.

• Current technology cannot affordably harness enough renewable energy power to meet electricity demand. Also, while wind and hydro power are considered by some to be viable energy sources, researcher and author Vaclav Smil contends that these two sources could only supply a small portion of future energy demand. Together, all renewable energy sources only constitute 8% of current worldwide energy supply, according to Smil’s book.

• Biofuels, such as ethanol, are not feasible future energy sources. With the challenges that global food supply is currently facing, we can no longer afford to use food as vehicle fuel while other alternatives are available. Many experts have linked redirected food supply used for producing corn-based ethanol to rising tortilla and livestock feed prices. “Ethanol is taking a larger and larger share of [corn] production,” says one agricultural economist.

Autogas and Gasoline Prices, 2009-2011

It’s no secret that gasoline is expensive, but what many Americans don’t know is the cost of the alternative. Autogas for America released a new Alternative Fuel Fact Brief on Aug. 24. The paper highlights how propane autogas, while as practical to use as traditional fuels, is cheaper and cleaner than gasoline. The study considers the big picture, pointing out that high gasoline prices are not just a burden to the individual consumer, but are crippling an economic recovery.

The study demonstrates that gasoline is not only an expensive resource, but also a volatile one. While the cost of gasoline nearly doubled in 2009, autogas prices remained low and relatively flat. Gas started at $2, and jumped all over the board from there. Historically, autogas has cost about $1.25 per gallon less than gasoline, when including a 50-cent-per-gallon federal alternative fuel tax credit. Some states even provide tax incentives for using alternative fuels like autogas.

For organizations already burdened by strained budgets, the high price of and uncertainty surrounding oil can complicate planning for the future. Everything from turmoil in the Middle East to declines in foreign reserves can drive up the price of oil. However, 90 percent of the U.S. autogas supply is made in America. While prices at the pump reflect instant savings for autogas fleets, autogas has also produced long-term savings. Vehicles running on autogas have been on American roads for years now, and real-world case studies show as much as $145,000 in annual fuel savings for fleets making the switch from gasoline to autogas.

The cost savings from autogas use offer more than just the immediate rollback for the consumer.  Lowering fixed costs like fuel expenses helps to create and save jobs, support a green energy economy and boost a company’s bottom line.
