These include metric to standard conversions, fuel consumption, air speed and distance calculations, and more.
But biofuels could account for 30% of all fuel consumption by 2020, some sources predict.
But stabilizing the effects of our unsustainable fossil fuel consumption requires more than high-risk technologies.

Reduce wind resistance and you can reduce fuel consumption by several percentage points.
Study after study has pegged energy efficiency as the lowest-cost way to curb fossil-fuel consumption and the resulting greenhouse-gas emissions.
WSJ: The Experts: What Will Be the Next Technological Breakthrough in Energy?
In 2009, Virginia Tech researchers found that there were some traffic calming measures that actually increase fuel consumption and emissions.
"Naturally, fuel consumption varies greatly depending on driving conditions, as well as the way the car is driven, " said Mr Baker.
However, given the current lack of a viable, affordable electric car, Chinese fossil fuel consumption is expected to continue to rise.
Small, shared vehicles are easy to park and maneuver in dense urban centers, and cut down on traffic and fuel consumption.
For instance, fuel consumption can be cut by about 1% by switching from conventional power steering to electronically controlled power steering.
From that we can assume passenger flights account for significantly more fuel consumption 68 percent compared to 32 percent for freight.
The 2010 Annual Energy Outlook projects that over 40 percent of U.S. liquid fuel consumption will be supplied by imports through 2035.

Consequently, the only way to decrease CO2 emissions per mile is to reduce fuel consumption per mile that is, increase fuel economy.
The current system is largely a waste of taxpayer dollars because it is redundant and it is counter-productive because it subsidizes fuel consumption.

Throughout the week, we monitored fuel consumption with discipline, and our facilities team did a commendable job in keeping the fuel deliveries coming.
This is based on total cost of ownership factors including depreciation, financing, insurance, maintenance, repairs, fees and taxes and, of course, fuel consumption.
"The bigger the ship the lower the fuel consumption, that's one thing, " said Thomas Riber Knudsen, Asia Pacific CEO of shipping line Maersk.
This creates a split-incentive, because the ship owner (who would pay for the upgrades) does not get the benefit of savings on fuel consumption.
One key change appears to be that people are making fewer journeys, although how much is due to fuel consumption is difficult to say.
After the test on the public roads in Spain, the project is now entering a new phase with the focus on analysis of fuel consumption.
