The USA: energy self sufficiency - political myth or reality?
(OP)
I don't want this to be political, as this isn't what this site is about. This is purely to ask you all as expert engineers just how the USA can become energy self-sufficient i.e. no longer dependent on outside oil.
This, it would appear, is one of the poiltical claims of the democratic presidential contender, that he will make the USA self-sufficient.
OK, sure, he can say to the Californians, sorry, but we need your offshore oil. But what, practically can he do and what will be the consequences either of him doing it, or trying to do it?
Of course, if I have misunderstood him, please tell me so. I'd hate to vote for the wrong loony.

RE: The USA: energy self sufficiency - political myth or reality?
Such a plan would have to be:
Socially acceptable by the public
Scalable
"Economical" (including any subsidies)
Sustainable
Capable of being incorporated into existing infrastructure
A worthy vision, but from my point of view, not something deliverable by the individual presenting it.

The only way for us consumers to change life style would be a permanent shortage of oil that would curtail gasoline supplies, and force the price per gallon of gasoline to $4 or $5. This would place enormous pressure on politicians to promote active development of alternative energy sources for cars (electric or propane fired) or enhancement of mass transit systems to allow people to commute from remote areas to urban locations.
RE: The USA: energy self sufficiency - political myth or reality?
What I know from intuition is that we live on a finite planet. The resources are finite therefore at some point in time we will not be able to use petroleum for fuel or plastics or asphalt pavement and whatever else we benifit from its existence. Hopefully, the right people with a social conscience AND the scientific capabilities know what the extent of our natural resources are and are helping to develop new technologies and/or political policy to help guide us and the world through the end times of the petroleum reserves.
As far as the democratic candidate is concerned he has been in the senate for twenty years - why is he bringing this up now? What has he authored in the ways of energy self-sufficiency in that time? Has he known (just since just yesterday) what the secrets are to energy independence?
RE: The USA: energy self sufficiency - political myth or reality?
So for your pleasure, here are the design parameters as I see them, feel free to add to my list.
The solution to energy independence:
1) Must not include the expansion of oil drilling activities any where in North America, but it is ok to drill elsewhere in the world.
2) Must not include the destruction or cutting down of any trees, or the elimination of any wetlands.
3) Should include the elimination of all automobile exhaust emissions except H20, or N2. NO3, CO, CO2, and volatile organic compounds are strictly forbidden.
4)Should eliminate any power plant emissions as well.
5) Cannot in any way create radioactive byproducts from any form of nuclear reaction. (Eliminates fission, and fusion as well).
6) Cannot impact the natural vistas of our countryside. (Elimanates wind power)
7) Cannot impact the natural ecosystems of our rivers or oceans, (eliminates hydropower and tidal conversions)
8) Must not involve the use of hazardous or polluting chemical (pretty well eliminates known photovoltaic systems).
9) Must not include the use of any pesticides, or genetic engineering (pretty well eliminates converting crops to energy).
I am sure there are more...
My conclusions? If we want to maintain the status quo, then we need to invade a country that has lots of oil, but no trees, and use it until their oil runs out. As long as the drilling doesn't happen here, it is no problem.
If we really want to satisfy all of the constraints above, then we need to eliminate the majority of the population, and return to a simple life of living off the land such as the native Americans did prior to North America being invaded by those nasty Europeans.

Hydrogen is no salvation either. Until you replace 100% of the electrical generation infrastructure with renewables (with or without nuclear, your choice), there's no net energy efficiency benefit to be had from hydrogen if the original energy source is fossil fuels. It might be a way for you to reduce oil dependency by using coal as your hydrogen source, but I doubt that would make the environmentalists too happy.
The only hope for true US fossil fuel trade independence would be a massive restructuring of your society. The majority of personal automobiles would have to go in favour of public transit. City planning would have to take a 180 degree turn, focusing around public transit and higher population density. You'd have to replace 100% of your existing oil-fired power plants with coal or nuclear so that the remaining oil could be refined for chemical and remaining transportation fuel uses. And you'd have to exploit your oil shale deposits on top of that.
If independence from Middle Eastern oil were the only goal, you could get by with massive investments in Canada's oilsands projects. Enough for 100 years+ at current consumption levels. Estimates are that the capital to do this would cost less than what the US spends on its military in a year. But this heavy oil is considerably less energy-efficient than the low lift-cost oil from the Middle East- it takes more gallons of raw material to produce a gallon of finished product, resulting in more carbon dioxide emissions.
But let's face reality here. It isn't going to happen. US culture is based around total dependence on cheap oil, and US foreign policy will take the directions necesary to keep up the supply of low lift-cost oil from the Middle East until it's utterly exhausted. Chinese and Indian consumption will increasingly drive up oil prices worldwide, and increased prices will lead to some pressure to reduce US demand, but I doubt you'll see the political will in the US to tax fuels at European rates. While fuel remains cheaper in real dollars than it was in the '70s, there's no real pressure to do anything to curb demand.
RE: The USA: energy self sufficiency - political myth or reality?
Metro services have proven to be the ideal means for the inner city poverty stricken to access the richer suburbs for the purposes of burglary and other larcenous behaviour. The better of suburbanites being well equipped with cars se less need for these public transport systems especially as city and payroll taxxes are what forced many of them out of the cities in the first place thereby concentrating the poor within the city where their is no work and no busines to pay taxes to pay welfare.
The modern city is an expensive luxury and we see many of the more affluent seduced by images of tranquile suburn or rural living fleeing to the countryside or semi-rural comunities. This isn't just an American probem. Berlin is bankrupt, and that country has very high unemployment but it is in the US where i believe the majority of the welfare bill falls on the city and not the state, or am i wrong here?
It isn't just a case of getting people out of their cars, it is what public transport will do to lifestyles that counts a much as anything and while curtailing car use might seem a simple enough solution, like anything else, it is the secondary effects that will cause the problems. You may pursuade people to use their cars less, but you may have a bigger problem if you want to channel crime into their neighbourhood, wittingly or unwittingly.

RE: The USA: energy self sufficiency - political myth or reality?
So, eliminate the big cities and have us all live in villages? I am not necessarily disagreeing with you. There is something in the small-town atmosphere which did, in the past, limit some crime and other problems. How do we deal with issues such as employment, tranportation/importation of goods and services and people?
Where do we put factories, a no-mans- land? or does each village have a blacksmith or high-tech micro-reactor.
Nothing like a good topic to provoke questions.
RE: The USA: energy self sufficiency - political myth or reality?
We should also remember that some of our isntitutions came into being under one set of circumstances and that those circumstances no longer exist. Hospitals are as recent as Lister, as we know them, and the trend is now back to small community hospitals and peripatetic surgical teams doing routine surgery locally, not yet back on your own kitchen table, but if the superbugs take over, it may come to that. Cities are the same. If we didn't have cities, would we want them today?
This isn't a forced change, it is a change more and more people are electing to take. It is society evolving as we live it!

RE: The USA: energy self sufficiency - political myth or reality?
Remove the cheap auto and fuel and you are left with a lot of people stuck in suburbia ( and rural areas) with no practical way to get to work. In particular, for persons of marginal income( working poor), a tripling of fuel prices would make it impossible to get to work, unless massive carpooling were to become fahionable for everyone ( only done today by undocumented immigrants).
I think the US would be energy independent if they reduced their oil consumption to 30% of current levels. Basically, one would need to revert to the lifestyle of the 1950's, or emulate the lifestyle of 3rd world countries , or emulate the consumptionhabits of most undocumented workers
( seriously- see how they make ends meet.)
RE: The USA: energy self sufficiency - political myth or reality?
So, having a bus between the city and the suburbs is welcoming crime into your neighborhoods?
News flash: The majority of the crime in your suburban heaven is committed by your suburban kids, who try oh so hard to make themselves feel like the "inner city thugs" they watch on MTV. I work with kids on both sides on a daily basis, and I will be the first in a long line of people to tell you that the kids from the cities are far less likely to break into your house tonight than the trust-fund brats who are raised in the 'burbs.
Funny enough, its these same suburban kids who you see driving around in the new SUV that daddy just bought for them. And when they're not cruising the streets, they are just idling in the McDonalds parking lot, complaining about how bored they are. Taking the buses out of the suburbs only puts more of these kids into cars. Not exactly helping ANY problem.
And really, who takes a bus to go rob a house? Wake up.

RE: The USA: energy self sufficiency - political myth or reality?
Again, it makes no difference urban or rural, our society would be unwilling to sacrifice cars. However, I just noticed that the price per barrel of oil hit $44 bucks, while the Dow and Nasdaq hit more lows. Just wait, if this trend continues we may be riding bicycles to work!!!!
RE: The USA: energy self sufficiency - political myth or reality?
I beg to differ. Here in the Boston area public transportation is very positive. Towns that have a stop are becoming famous almost at a celebrity level. Real estate has gone up ridiculously in these towns. These towns are now becoming more of an up and coming white collar communities. Where people who make the Boston salary and live and spend it in the suburbs. The people who use the public transportation are praising it. They have a strait shot into Boston versus being stuck in traffic and then get there and look for parking. A parking space in Boston can cost $100,000.00 or more! I know guys who will not drive into Boston. They would go to a town that has public transportation and take the train in.
“Metro services have proven to be the ideal means for the inner city poverty stricken to access the richer suburbs for the purposes of burglary and other larcenous behaviour.”
This has the flavor of a politician just saying the wrong statement at the wrong time. I grew up in NYC and I knew some shady characters and trust me, they would not take a train out to the suburbs, walk five to ten miles to the nearest sweetest target, rob it, then walk five to ten miles back to the train. Even if inner city kids just wanted to hang out, there is no place for them to hang out in. Most stops in the suburbs are just really big parking lots. Boy that is exciting. There is no reason what so ever for inner city teens or young adults to take the train out to the burbs.

There is no engineering solution to vainity... and too many Americans use personal automobiles as an extension of self image, or rather- that image they'd like to extend the public.
Sometimes this overwhelming pressure to "express one's personality" through a nice car overshadows the necessity of efficentcy and energy conservation in today's USA. The true scope and definition of the issue escapes the mass public consciousness.
RE: The USA: energy self sufficiency - political myth or reality?
A little background info for those who read: Hydro One is a corporation that was created as a result of the Priviatisation of Ontario's energy grids. One of the worst mistakes made in our Province's history... in my opinion at least.
Many people reading this will undoubtedly remember the 2003 blackout that they mention as well... Still, it was nice to see the stars from the roof of my building, a rare occurrence in the city.
Further down the article speaks about a Laundromat in Toronto that uses Solar Power to pre-heat the incoming water, reducing the load on the Natural Gas boilers. They also use city water to cool the air during the summer time, the warmed water then being used as Hot water in the laundry machines.
I had the opportunity to visit this laundromat a while back. The answers to many of the USA's, and indeed the rest of the world's upcoming energy issues can be found just by taking a look at solutions like this, and then looking beyond at how else we can reduce our dependence on something that won't always be there.
The policies in question are the ones that would offer benefits to people and businesses who use these systems, helping to offset the initial cost of the equipment. As of now, it is difficult to see the rewards in being energy conscious, especially when you have Ol' Tex in the White House backing out of almost every energy saving initiative (ironically, his Texas ranch uses Geothermal power, and is a model of energy efficiency... Does he know something you don't???).

RE: The USA: energy self sufficiency - political myth or reality?
If American drivers can't accept electric-powered cars right away, there will be hydrogen fuel cell vehicles and eventually H2-burning internal combustion engines (they already have a mostly-stock Mazda RX-8 prototype running on H2.) H2 can be safely cooked up in your garage each night, in an appliance fed by your electric service and water utility. Diesel oil would still be needed in the long term, but by replacing much of our current fuel with smarter coal combustion, it can be cut back to levels US sources can support.
Power companies will resist buying new technology when their current plants still have 30 or more years of life remaining. But politicians do have the power to remove those barriers-to-entry the government puts in place to insulate the well-connected power lobby from competition. This will take political courage, to accept campaign donations from the entrenched power companies (as each candidate has) and then "allow" small co-ops to use new technology to compete against them, new technology even the government is actively funding:
http://www.fe.doe.gov/programs/powersystems/index.html
We have enough coal within our borders to support current usage and growth rates for at least the next 300 years. By then we'll have solved our dependence on domestic coal, probably with a big mirror in orbit that reflects concentrated sunlight down to a photochemical power plant on the roof of your great-great-great-great grandson's house, or other method satisfying all of sms' criteria listed above.
RE: The USA: energy self sufficiency - political myth or reality?
Fuel independence will probably happen first by necessity.
I personally believe that it will come in 3 stages. The first one will take advantage of infra-structure already in place. Biofuels such as biodiesel will lead the path and scratch the surface. Presently, short term goals are to produce 400 million gallons of BD per year. Long term goals are to reach 8 billion gallons/yr. We consume well over 50 billion gallons of BD per year. 8 billion will overreach our waste oil/recycled oil and farmed oil resources as of now. Stage 1 will be extended by farming more efficient biomass such as mustard and algae, and making a real market out of trap grease (an additional 8 billion gallons). In theory, 1 hectacre can output 10,000 gallons of biodiesel per year with algae farming procedures currently in place, and a 100% energy efficiency.
This is still a far stretch from independence.
I may have the stages predicted wrong, because I believe the second stage to be thermal depolymerization. Oils and other fuels will be produced at an 85% efficiency, which is okay, and in the near future may compete with foreign oil. This technology will allow for fuel conversions from the current gas powered vehicles on the road. Natural gas internal combustion will actually become an industry. Waste treatment plants may become thermal depolymerization plants, or biodiesel plants. The latter being more energy efficient (560% as opposed to 85%)
The third and final stage will be manifest of the first two stages. The efficient usage of carbon-sink byproduct. Specifically, I believe that all of the glycerol product of biodiesel, and biomass CHO product for biodisel, and all other biomass waste will eventually be used in aqueous phase reforming. Eventually we'll figure out how to use AFR on fibrous biomass. That is, H2 will be a main byproduct and hydrogen fuel cell technology will have a purpose. The H2 made from biological sources will be cost competitive with foreign sources by 2025 by current projections. This is a 100% (or so) energy efficient process, but catalysts currently make this process uncometitive with petro H2 produced from natural gas.
I believe that the most efficient of these processes will eventually be "naturally seelected" based on efficiency. Thermal depolymerization will be a strong force from otherwise useless waste. Soon we will learn that H2 technology allows for the hydrocarbon energy to be used, AND we can sequester the CO2. This may be our future.
RE: The USA: energy self sufficiency - political myth or reality?
The first, essential and of course politically impossible step in all of this, though, is to tax stupid, wasteful consumption of fossil fuels to rebalance the economic equation in favour of alternatives.
Anyone who understands energy techology knows that there is no simple technological fix for our energy woes. It isn't coal, bio-derived fuels, nuclear, hydrogen or even fusion. Technological first aid of the bandaid variety, perhaps, but no true "fix" is available from any of these energy sources, as all of them have environmental, societal and economic consequences. Those who idealize the technological fix generally fall into two categories from what I've seen: politicians etc. with little technological background, and technological people who are touting their products as part of the "fix"...
