Military Biofuel Costs Slashed Thanks to Massive Navy Purchase

Fuel is still nearly five times as expensive as traditional fuel
For better or worse the U.S. military is trying to fight an "army of one" campaign to
switch its massive fuel consumption base
to domestic biofuels, safeguarding itself from foreign volatility. And despite some small bills to the U.S. taxpayers the push appears to be working.
Biofuels work pretty much like any production industry -- you produce more, and price per unit drops. Back in October 2010 the Navy purchased 20,055 gallons of
whopping cost of $424/gallon
. At the time that was one of the biggest U.S. purchases of a (non-corn ethanol) biofuel to date.
Fast-forward a year and the Navy is back at it. It's
a reported $12M USD to get 450,000 gallons of biofuel. The bad news? The fuel cost works out to around $26.67 per gallon -- around 6 to 8 times as much as traditional gas. The good news? The cost per gallon has plunged by a jaw-dropping factor of 15.9.

While the incredible cost reduction is unlikely to continue at its current pace, the purchase validates something some national security and environmental advocates have been emphasizing all along -- if you produce more, costs will drop.
The latest fuel purchase is a mixture of repurposed cooking oil ("yellow grease") from Tyson Foods, Inc. (
) and algae-based oils from Solazyme, Inc. (
). Tyson is current partnered with a refining company named Syntroleum Corp. (
) in a joint venture called Dynamic Fuels. The Navy's contract is with Dynamic Fuels, who has signed a subcontract with Solazyme to buy its algal oils for refining, to help fill the large order.
Navy Secretary Ray Mabus lauded the purchase as helping to grow the domestic biofuels market. The fuel will be used to help power the Navy's "green" Carrier Strike Group during exercises in the Pacific Ocean next summer.

The Navy, which uses 80,000 barrels of oil a day (3.36M gallons/day), has made the amibitious pledge of getting 50 percent if its fuel from fossil fuel alternatives by 2020. At current demand levels, that would work out to around 613M gallons of biofuel a year.
It's not alone in that objective. The U.S. Air Force now has
98 percent of its aircraft
ready to run on a biofuel blend (though the allowed amount of biofuel in the blend is application-dependent).
The U.S. Armed Forces accounts for about 2 percent of total U.S. fuel consumption. Of last year's approximately 4.62 billion gallon, $15B USD fuel budget, 75 percent was used in overseas operations, while 25 percent was utilized at home.

Well solar is actually viable. 10 % of the federal land of nevada could power the united states.
Cost is up front more expensive pr. kwh than example nuclear.
Factor in 30 year fuel/maintenance on both sides and its cheaper to run a solar.
Sun doesn't shine. Well, there is allready two solar farms in spain using salt heat retention to run nearly 24 hours a day. A full system running 24h is economically viable and technically feasible. Essentially creating a huge battery thaat can be tapped on demand.
But a country will never rely solely on solar. Its just not smart to put all your eggs in one basket. But it could probably do 80% of the work, converting some 10% of desert area to powerplants.
I think the last was a 2 billion project designed to provide peak power demand.
A couple of terms for google if you want to know more.
