Ground zero in the energy-water nexusthe oil and gas producing countries of the Middle east may be sitting pretty in fossil fuels,
since it burns more than 1 million barrels a day of crude oil just to desalinate water.
when its fossil fuel resources are depleted sharply and its groundwater is gone. In time after a long process of cultural change, even the 16 percent of the UAE's crude oil production that is consumed internally--nearly half a million barrels per day--might be reduced as more electric vehicles,
such as the ones being used in Masdar City, take to the roads. It might not take much more than Sheikh Mohammed letting his people see him rolling around downtown in a snazzy,
saying that it had not been able to offset the rising cost of jet fuel. Australia's Qantas Airways reported last month that high fuel costs had halved its profit in the first half of 2011
and that it would cut 500 jobs in a bid to save the company. Airasia X announced this week that it is suspending service to New zealand due to unprofitability,
Also this week, Israel's El al airlines announced higher fuel surcharges, eliminated its service to Brazil
when it ran out of money to pay for fuel, stranding its customers without offering them alternative arrangements.
Unfortunately, there is little that the airlines can do to accommodate an era of permanently higher fuel prices, other than raising their own prices accordingly.
There's no way that the trucking industry can absorb fuel costs it can't happen, trucking company owner Jim Ganduglia told ABC News. Where he operates in Fresno, California,
So there's a fuel surcharge and without that fuel surcharge we'd all be out of business.
Nowhere is the cost of trucking more evident to consumers than at the grocery store. Fresh produce and other perishables must be shipped promptly no matter
Operators of small fleets, like Phoenix-based HVAC repair shop George Brazil Services, try to maximize their fuel efficiency by switching to more efficient vehicles
Optimizing the behavior of drivers is another fuel-reduction strategy advocated by companies like Dubai-based Dynamic Technical Training.
they have shown that fleet operators of 100 vehicles can save $31, 500 annually in fuel costs.
and engaged in a long campaign to upgrade the fuel economy of their fleets, the main recourse is to simply keep raising their fuel surcharges.
One year ago, the surcharge was 5. 5 percent. Now it's 7. 5 percent,
Farmers Farmers are being forced to find ways to conserve fuel as well. Although most consumers do not realize it,
an estimated 7 to 10 calories of fossil fuel are embedded in every calorie of food that arrives on American tables,
but they are forced often to absorb fuel price increases because they can't pass them along to consumers.
in order to save on fuel. We'll think of ways, maybe make less passes through the field with the tractor than we normally would have.
This highlights a somewhat counterintuitive result of rising fuel prices. While it's true that organic farmers generally use less fuel than conventional farmers,
Logistics managers are increasingly considering it as a way to maintain profitability in the face of rising fuel costs.
Next-generation biofuels are viewed often as a transportation fuel panacea. A magic elixir that will wean the U s. off of foreign oil without sending the economy into the dark ages.
Advocates have promised next-gen biofuels will reduce greenhouse emissions and end the use of food crops for fuel.
said it's unlikely the U s. will meet specific biofuel mandates under the Renewable Fuel Standard by 2022
the consumption volume of renewable fuels hit 36 billion gallons. Â Of that, 15 billion gallons must be conventional biofuels--aka corn-based ethanol
Not a single commercially viable biorefinery exists for converting cellulosic biomass to fuel, the NRC said.
and converting it into fermentable sugars so it can be refined into fuel is too expensive to be commercially viable.
The NRC notes other difficulties with cellulosic biofuels including its reliance on subsidies to compete with fossil fuels
and increasing the conversion yield from biomass to fuels--something that's already happening, albeit more at a more limited scale than is perhaps necessary.
One of the goals I had was to get the house off heating fuel (it was an old cast iron steam system with an oil burner,
The state of Maine is more dependent on home heating fuel than any other state. More than 85 percent of homes are heated with oil.
So part of our struggle is to get ourselves off fuel, and that s part of the $11 million bond:
along with liquid fuel. We're also producing a very low-cost product for the developing world.
Talk about the liquid fuel that can be produced by the device for the developing world. It's called bio-oil.
It's a low-grade crude oil substitute. We can upgrade it to a point where it can run a diesel generator.
Up to 80 percent of people rely on it as a fuel source. The price of charcoal is highly volatile.
Hydrogen fuel made from a tiny forest of nanotreeselectrical engineers at the University of California-San diego have built a forest of nanowire trees that use solar energy to turn water into  hydrogen  fuel.
Hydrogen fuel is considered a clean fuel because it doesn't generate carbon emissions. However, the conventional method of producing hydrogen gas relies on energy from fossil fuels to separate the atoms from other molecules like water.
Deli Wang, professor in the Department of Electrical and Computer Engineering at the UC San diego Jacobs School of engineering
and his team sought out a way to cleanly capture solar energy without using fossil fuels and harvest it for hydrogen fuel generation.

Khera advocates reducing other subsidies like those on fuel (in 2011-2012 to the tune of 1. 4 trillion rupees or $27. 7 billion),
which is nearly 25 times the amount of carbon is released annually to the atmosphere from combined fossil fuel burning and land use changes.

more carbon dioxide than crude oil, and approximate the emissions of the much-maligned oil mined from tar sands.
And with ILUC added to the mix, it looks like some top biofuel crops are worse for the environment, in terms of carbon emissions, than crude oil.
The EU's default value for measuring carbon efficiency for oil from tar sands is 107g CO2 equivalent per megajoule of fuel (CO2/mj.
Meanwhile, crude oil's efficiency value is 87. 5g CO2/mj. Here are the data (g CO2/mj) from the EU documents,

but they are much less expensive to feed than a power mower is to fuel. Won't some people take issue with farm animals trampling all over their dearly departed?
The truck uses 30 percent to 50 percent less fuel than the alternative. On 25 of its larger semi delivery trucks, Oakhurst will install side panels that are supposed to improve aerodynamics and,
therefore, fuel efficiency. The dairy figures that it will save between 6 percent and 8 percent in fuel costs based on current driving habits (an average of 30,000 miles annually per truck.
The retrofit should be completed by the end of 2010. The dairy figures it will cut about 7. 6 million pounds of carbon dioxide emissions annually through the retrofit.
bamboo has provided biomass fuel at power plants in the Philippines. Don't worry graphene. As far as I know,
Why it matters The federal government has mandated that 36 billion gallons of renewable fuel be blended into transportation fuel by 2022.
and converting it into fermentable sugars so it can be refined into fuel is too expensive to be commercially viable.
Another mandate missed (and by a lot) Another year, another missed renewable fuel production mandate. The Environmental protection agency released this week its 2012 targets for renewable fuels
and once again next-generation biofuels will fall far short of the production volume mandated by Congress.
Meanwhile,  less than one-tenth of 1 percent of renewable fuels produced next year will come  from cellulosic ethanol-- the transportation fuel panacea expected to wean the U s. off of foreign oil

-and corn-based ethanol to meet the national mandate for renewable fuels in 2012. Unfortunately, this annual ritual of missing mandated production targets is likely to continue.
A National Resource Council report released in October said it's unlikely the U s. will meet specific biofuel mandates under the Renewable Fuel Standard by 2022
Not a single commercially viable biorefinery exists for converting cellulosic biomass to fuel, the NRC said.
The renewable fuel standard requires refiners to either purchase cellulosic ethanol or buy waivers. In other words, refiners have to spend money to meet mandates that can't be met.
E coli bacteria that eats switchgrass to make fuel How do you solve a problem like next-gen biofuels?
RTI International received a $1. 3 million grant to fund the development of a self-contained toulet system disinfects liquid waste and turns solid waste into fuel or electricity through a biomass energy
and feedstock costs enough to make their product competitive with corn-based ethanol and ultimately fossil fuels.

which has helped fuel our exploding population and our overwhelming population is now causing even more problems.
These are things we should be doing right away to buy us some time to solve the harder problem of how to stop burning fossil fuels.
Eighty percent or more of our energy is still coming from fossil fuels. Eventually we need to go to zero or negative with our CO2 emissions.
there are still parts of the world where wood is the primary fuel source. We need to get started on our transition from fossil fuel burning
so that we can complete the transition in time to save human civilization. That is if we want the Anthropocene to be more than a blip in the geologic record.
even if we burn all the fossil fuels, the planet as a rock will survive and so will a lot of the life on the planet,
They are trying to get us off fossil fuels. SP: Are they as â Å out there â Â as their brother, DARPA,

by taking sunlight and somehow turning it into a fuel that you can burn. We are going to need every little bit of innovation to displace the burning of fossil fuels.
SP: What does success look like to you? DB: Success has three parts. One is a resilient and robust human civilization.
The fuel is cheap and inexhaustible. Green nuclear power can solve the global crises of air pollution deaths and climate change.
 Hargraves is particularly keen on a reactor that uses liquid thorium fuel instead of solid uranium,

As a corporation, Sappi Fine Paper established a goal to reduce its emissions from fossil fuels by 40 percent between 2008 and 2013 against a 2007 baseline measurement.
and the produce does need not to be shipped long distances, conserving precious fossil fuels. Farmedhere employs local workers to reduce transport requirements.
That reduced erosion, the runoff of chemicals into waterways and the use of fuel for tractors.
Freitas points out that the isotope gadolinium-148 could provide much of the fuel the body needs.
Corn-based ethanol costs $1. 40 a gallon to produce, according to the Renewable Fuels Association.
May Wu, an environmental scientist at Argonne National Laboratory, says Coskata's ethanol produces 84 percent less greenhouse gas than fossil fuel even after accounting for the energy needed to produce
"Still, consumers will need some way of getting that fuel into their vehicle. Less than 1 percent of the nation's 170,000 gas stations sell E85, said Mike Omotoso, senior manager of the global power train group at J. D. Power & Associates."
"People aren't going to go to some remote location for fuel.""But with production set to ramp up quickly to meet the 36 billion gallon mandate,
and because low-income and poor families are faced with higher fuel and housing costs, they are still unable to buy sufficient food
The fuel of the futureone has to ask oewhat the hell were they thinking? Clearly, instead of thinking, the EU political elites were seduced by Greenpeace, FOE and similar activists.
By far the largest so-called renewable fuel used in Europe is wood. In its various forms, from sticks to pellets to sawdust, wood (or to use its fashionable name, biomass) accounts for about half of Europe renewable-energy consumption.
38%of non-fossil fuel consumption comes from the stuff. After years in which European governments have boasted about their high-tech
low-carbon energy revolution, the main beneficiary seems to be favoured the fuel of preindustrial societies.
