Gas Prices - A Load of Hot Air?

When George W. Bush is the man making the most sense, you know you've got problems.

But yesterday, he stood up in front of the nation and was surprisingly honest about America's imminent fuel crisis - admitting "If there was a magic wand to wave, I'd be waving it."

Petrol prices in America have been rocketing up. Prices at the pump have more than doubled since George Bush took office and in all fairness, not all of the blame can be laid at the doorstop of the White House. America's reliance on oil has been an Achilles heel for many years. The worry is that we've reached breaking point.

Presidential candidates Clinton and McCain are both launching rhetoric designed to tackle the rising fuel costs, but President Bush is right. There is no magic wand to solve the problem of expensive fuel and the only way forward is a longer term solution.

But what's causing the rocketing fuel prices?

One of the major reasons oil is becoming more expensive is because there's less of it. For decades, we've known that oil is a limited resource and the 'black gold' that does remain buried is getting more and more expensive to pump. Hence rising prices.

Secondly, global demand is increasing. Both India and China are becoming major oil consumers and the more demand there is for a limited resource, the more the suppliers can charge for it.

Thirdly, there's simply less oil in circulation. Before George Bush advocated invading Iraq, Saddam Hussein's regime produced 3.5 million barrels of oil a day. Since the invasion, the same country has struggled to sustain 2.3 million barrels of oil a day and this oil costs more to produce because of the increased security. That's more than a million barrels of oil taken out of circulation every single day.

Lastly - and importantly - the real 'oil giants' of the world (the OPEC members like Saudi Arabia) are holding the world's oil supplies ransom. They control the vast majority of the available oil resources and because demand is increasing, they can charge pretty much what they want for it.

Although President Bush has called for OPEC to release more oil for sale, you can't really blame the Organization of Petroleum Exporting Countries for refusing to do so. At the moment, they can sell their oil for a specific price. If they released more, that price would drop. Therefore, to meet the same profit level, they'd have to sell more of their commodity. It's basic business to charge the most that they can for their oil and the fact that we're all still willing to buy it suggests that this is a very successful strategy.

OPEC is a very powerful organisation. Their stranglehold on the oil industry inspired the gas crisis in the 70's, when the Shah of Iran warned America: "You buy our crude oil and sell it back to us, refined as petrochemicals, at a hundred times the price you've paid to us...; It's only fair that, from now on, you should pay more for oil. Let's say 10 times more."

Basically, the reason oil is so expensive these days has little to do with the White House. It's the law of supply and demand and the manipulation of OPEC. The only influence the federal government has on the price of petrol is in the tax they stick on it - which both John McCain and Hilary Clinton advocate dropping during the summer to cut the price at the pump.

It's an impotent gesture. For the average consumer, an entire summer's worth of savings would realistically only save them $30 or $40 dollars.

What can we do?

In the short term, the easiest solution to the oil crisis would be to find a new and plentiful source of cheap oil, to lower the overall cost of fuel and cut the legs from under the OPEC blackmailers.

George Bush suggests drilling in wildlife reserves in Alaska, which might well produce a plentiful new supply, reduce America's dependence on foreign oil and give us all a break when we fill our tanks.

There are several problems regarding this, however.

Primarily, drilling for oil in Alaska would devastate the wildlife. Wiping out species of birds and animals all for the sake of a cheaper fill-up seems rather wrong.

Secondly, it's a short term solution. Oil is running out. How much oil is there in Alaska? How long will it be before that runs out as well?

And thirdly - perhaps most importantly - the continued burning of oil and other fossil fuels is permanently damaging the environment. The question of how long the Alaskan oil will last might prove to be redundant if we oven-bake the globe exploiting it.

Alternative Suggestions

There are alternatives - and one of the reasons America's in such a crisis at the moment is because these alternatives are being explored in an utterly incompetent fashion.

The most touted solution to the oil crisis are alternative sources of energy. Sustainable organic fuels. Clean and renewable energy generation. The technology exists now and with sensible investment, we could solve the world's energy crisis practically overnight.

But misguided environmentalists and greedy politicians have utterly messed up the whole process.

As far as gas prices go, oil used for generating power could be diverted into the fuel market if America adopted clean, safe nuclear power. Instead, we still have costly, cumbersome and environmentally apocalyptic coal and oil fired power plants.

Nuclear power is clean and safe. France has successfully relied on it for decades. Yet the shadows of Chernobyl and misguided environmentalists argue about the perceived 'danger' of nuclear power and stand in the way of America finally fixing it's rickety and outdated power grid.

This is the twenty-first century, yet California continues to have 'brown outs' and power cuts because of primitive power-plant technology. This is really unacceptable.

When it comes to fuel itself, an alternative to petrol already exists - ethanol. Clean, cheap and easy to produce, ethanol could pretty much replace petroleum with very minor upgrades to most vehicle's fuel system.

Yet greedy politicians have created an ethanol stranglehold almost as wretched as OPEC's claw-like grip on the global oil market.

Ethanol is produced from organic crops. The vegetation you use to produce ethanol effects the power to production ratio involved in making it. In Brazil, sugarcane ethanol generates about eight times as much energy as it takes to produce.

In America, however, the vegetation of choice is corn - which has a pathetic one-to-one power to production ratio. Basically, it takes as much energy to make corn-based ethanol as the ethanol actually produces when poured into a gas tank.

That's simply unsustainable.

But it gets worse. The likes of environmentalist Al Gore have pushed so hard for the production of ethanol that they've given American farmers enormous subsidies to produce it - and whacked a 52 cent import tariff on ethanol imported from overseas.

This means that American farmers are using food-crop to produce ethanol, rather than corn flakes, which is shooting up the cost of food across America. In addition, the expensive fuel they produce is no cheaper than imported gasoline. What's worse, the cheap ethanol from overseas (that could be mixed with American petrol and actually bring the pump-price down) is no longer priced competitively because the government has slapped a tariff on it.

Basically, Al Gore and his cronies have successfully tied up American ethanol production with so much red tape, graft, greed and corruption that it's effectively a dead end. A self serving money-generating gravy-train for a few politicians and thousands of farmers.

If we're going to end the fuel crisis and finally give America sustainable and cheap power, here's what we need to do:
  1. Build nuclear power stations to replace the coal-fired ones. This will make a huge difference to the environment (but put thousands of coal miners out of work. Still, it worked in England.)
  2. End the subsidies for farmers to produce ethanol from corn. That corn will return to the food-market and lower the cost of groceries across the country.
  3. End the tariff on imported ethanol. This will mean that cheap, efficient ethanol can be mixed with petrol in the short-term to lower the price at the petrol pump.
  4. Research and develop cheap, clean efficient alternatives to oil. They already exist. We just need to make them practical.
Given the corruption and incompetence in government, plus the stranglehold of the misguided environmentalists, I can't see this happening any time soon.

Ethanol...

While we're on the subject of fuel (see my previous post, The Great American Gas Swindle Revisited) I thought it might be worth writing a bit about ethanol.

I'm not an expert! This is just stuff I've read online and in The Economist. But it all seems pretty credible to me.

What is Ethanol?

Ethanol is a petroleum substitute made from various organic sources, such as sugarcane or, in the United States, corn. Presently, a mix of 10% corn-fuel ethanol is added to most of the petrol in the United States, reducing our reliance on foreign oil.

On the surface of it, ethanol looks absolutely fantastic as a replacement for petroleum. First off, it's pretty much a standard replacement. Most modern cars could run on 100% ethanol fuel without any adjustment whatsoever. Even old clunkers like mine could run pretty easily on ethanol once some of the gubbins had been adjusted.

Secondly, we can produce ethanol fuel in the United States, which is awesome. It's a renewable resource, unlike oil (which is rapidly running out. Currently, the supply can barely meet the demand.) Additionally, the three major suppliers of oil to the United States are Venezuela, Iran and Saudi Arabia. Venezuela and Iran hate our guts, while 'friendly' Saudi Arabia was the birthplace of no less than 15 of the 19 hijackers responsible for 9/11.

So on the face of it, roll on the production of corn-ethanol! Let's cut the apron strings from the likes of Venezuela and Saudi Arabia. We'll see how far their anti-American rhetoric gets them after their economy is robbed of American oil-dollars.

But, sadly, it's not as simple as that. Is it ever?

Corn vs. Petrol.

The problem with the type of ethanol America produces is that it's not an efficient source of fuel.

Although production of ethanol in Brazil and other southern countries seems to work very well, this is because it's based on ethanol produced through sugarcane. Sugar is a highly efficient energy source and it takes just 1 'unit' of regular energy to produce 8 'units' of ethanol energy.

Unfortunately, sugar doesn't grow very well in the United States, so we're left using corn. The problem is that corn doesn't have a very good energy balance. In fact, it takes almost one and a half units of regular energy to produce a single unit of ethanol energy.

This simply doesn't make sense. If you're using traditional sources of energy to produce corn ethanol, you end up burning more oil or coal than you produce. It's utterly unsustainable.

Secondly, corn-ethanol requires crops to produce it. A lot of crops. To replace the 140 billion gallons of imported fuel used by America every year, you'd have to plant corn over every single inch of the United States... and then some.

Not to mention that corn-ethanol produces just as much CO2 as regular petrol, meaning it's just as bad for the long-term future of the environment (contributing to global warming.)

As it is currently, it doesn't look like corn ethanol makes any sense as a replacement to imported foreign oil. But there is hope...

The future...

Cellulosic ethanol is a possible alternative source of ethanol. Cellulosic ethanol is fuel produced from lignocellulose - the 'stuff' that plants and trees are made from.

This type of fuel is made by breaking down the lignocellulose with water or gas and then fermenting the generated sugars. Basically brewing a type of rum your car can drink!

The advantage is that garbage itself (like cardboard and wood) could be used as a base to produce this fuel - and the production itself generates 80% less CO2 which will make a dramatic reduction in America's contribution to global warming.

But the best part is that it takes just 1 unit of regular energy to make 5 units of cellulosic ethanol - and it's cheap, too. Within 10 years, it's estimated that the cost of a gallon of cellulosic ethanol will be about $1.07. That's compared to regular petrol, which costs between $1.20 and $1.50 a gallon.

It's still early days for this fledgling fuel - but it's an exciting proposition. Perhaps within the next decade, we'll see the clock turn back to the golden age when the United States was self-sufficient!

With the economy in the doldrums and the news looking ever bleaker, it's quite exciting to peek at something positive on the horizon.

Roll on cellulosic ethanol. The gas-tanks of both my American guzzlers are eagerly awaiting their first taste!
