Links and facts to back up this statement?

Advantages of electricity are:

- cheaper and faster to put in power lines than to dig and bury a large gas line

- Electricity is quickly dispatchable for load balancing. Flip some switches and electricity can be moved at close to the speed of light. Gas can take days to cover the same distance.

- Electricity can have a smart grid, gas cannot.

- energy needed to compress and move gas through a pipe is a lot higher than pushing electricity through a wire.

- improvements needed to the electricity infrastructure to handle vehicle charging are consideralby less than the improvements needed to bring CNG to homes, highways and gas stations

If the electric vehicle industry can crack the battery problem, then they win.]]>

I don't think so. The Yuan is tied to the dollar, so a falling dollar causes it to fall with it. That's why with the USD down about 40% from its year 2000 high the cost of Chinese imported goods remain cheap. If anything there are more signs of deflation in the US economy than inflation.]]>

Thoughts on Energy Trading Position Limits http://seekingalpha.com/article/170442-thoughts-on-energy-trading-position-limits?source=feed#comment-741121 741121 ===

OK, well, I've never seen evidence of banks in "control" of the markets. In Congressional testimony, a hedge fund manager pointed out that hedge funds, pension funds, ETFs, etc., increased their positions in futures contracts from $13 billion to $260 billion from 2003 to 2008. It was a huge momentum trade, making a profit on the rollover from one contract to the next, and never taking delivery of the oil.

So much money poured in that the price got disconnected from the actual demand for oil.

In a normal free market, prices are high when goods are scarce. When the price of oil hit the peak, world oil storage was full. America's top oil storage facility, Cushing Oklahoma, was turning away oil. The fact that prices were high while oil was in surplus -- is strong proof that the oil futures market was distorted and unbalanced by financial players.

People need to understand that if you truly want the free market to exist in the futures markets, we need to limit participation to professionals who actually produce and consume the commodity at the wholesale level.]]>

Speculators Keep the Market Liquid http://seekingalpha.com/article/156565-speculators-keep-the-market-liquid?source=feed#comment-634729 634729
Everyone knows what really happened in 2007-08. Hedge funds, pension funds, ETFs, etc. poured billions of dollars into energy futures. Trend followers jumped in. As long as the price went up a few dollars every month with the rollover, the trend kept going.

The problem is that the financial speculators never take delivery of physical product. Futures markets work best when most of the participants actually produce or buy the product at the wholesale level. That's when supply and demand are truly in balance.

When oil ramped up to $150/bbl under a normal supply-and-demand regime you would think there would be a shortage of oil. The opposite was true -- inventories were very high. That's because the financial demand for futures got way ahead of the physical demand for oil. Position limits on financial speculators (but not industry hedgers) are a good thing and will help keep futures markets undistorted.]]>

Since I'm new, can you reconcile that statement with this for me please? (link to UNG's SEC filing)

===========

I laughed when I read UNG management's "defense" in its SEC filings. They best they could do was a simple price chart? The elephant in the room they tried to ignore is, how much more would the price of NG gone down if UNG hadn't been pouring money into futures?

Regardless, I have to discount UNG's own arguments -- they obviously are not an unbiased source.

Credit Suisse's energy analyst says,

"A wave of UNG purchases in May occurred in the absence of natural shortsellers in the market, creating a sort of self-fulfilling prophesy. UNG buyers may have been purchasing shares on the belief that the price of gas would rise and cause it to gain ground from the lows set in April. Up until last week’s sell-off, the floor for gas prices had seemingly reset $0.50 higher, based on the ebb and flow of UNG fund. However, during June, even the increased surge of investors into UNG has failed to lift prices above $4.50.”

“We believe one of the primary reasons the market was unable to rally above market highs set in May was that there were a number of producers that began to add hedges in June in order to capture the improvement in the curve. A temporary restriction preventing UNG from issuing additional units, and subsequently purchasing incremental contracts of natural gas, means that the season’s most important buyer has stepped to the sideline. The vacuum created by UNG’s absence in the gas market seems likely to lead to continued pressure on prices.”

Wall St Journal, July 16 "Natural-Gas Prices Slide as a Key ETF Can't Buy" -- discusses how UNG's trading halt pulled the rug from NG's price.

I can't see how another add vs. reduction *proves* that UNG distorts.
========

Drillers have been eating up 2010 hedges at $6 and $7. Now take UNG's $3 billion of market cap out of the market, how much lower would the 2010 prices be? If 2010's were at $3 or $4 absent UNG then drillers wouldn't be so eager to hedge because they can't make a profit at that price. And so what UNG is doing is encouraging more drilling even when more physical gas isn't needed.

========

Can you explain to me these prices 2000-2008? Prices rose *long* before UNG existed. Look at this chart.

========

The 2008 bubble was driven by hedge fund money, Amaranth, pension funds, etc. -- UNG was a very small player then (as the chart shows). Basically what we're seeing now is that UNG is the new Amaranth, a dominant player, but without the speculative positions.]]>

Stocks have a fixed float, futures do not. As money pours into UNG, more and more front month contracts get written, sending a signal to the markets that there is a huge demand for natural gas. But wait! This is a false signal because UNG holders never take physical delivery of the product. As a result the linkage between the true physical demand for natural gas and the financial demand for natural gas contracts is broken.

Once the front month ends, UNG has to roll its huge holdings into the next month. This again creates an artificially high demand for contracts, pushing up the prices and making the contango steeper than it would be if the number of contracts actually represented the physical demand.

Proof that UNG is distorting the markets is that the gas rig count went up last week despite record inventories. UNG pushes up the price, giving an incentive for drillers to drill, making the inventory even bigger. This is key: if you buy UNG, your own money is used against you to increase supply!

Gas would probably be below $3 if UNG never existed. The end result of all this will be higher utility bills for electricity and home heating.]]>

1 gallon of gasoline = 125,000 BTU
1 kW-h of electricity = 3413 BTU
Battery on Volt is 16 kW-h.
Range on battery only is 40 miles.
16 kW-h = 54600 BTU = 0.4 gallons of gasoline
40 miles / 0.4 gal = 100 mpg energy equivalent

... but you paid maybe 10 cents per kW-h at your home power plug, or $1.60 to charge the battery.
Assuming $3/gal gas, $1.60 is equivalent to 0.53 gallons.
40 miles / 0.53 gal = 75 mpg price equivalent

True answer seems to be around 75 to 100 mpg, which is very good, but it's not 230 mpg. ]]>

How Natural Gas Can Save the U.S. Economy http://seekingalpha.com/article/155434-how-natural-gas-can-save-the-u-s-economy?source=feed#comment-627137 627137
We know that the Chevy Volt will be rated EPA about 230 mpg and the Nissan Leaf over 300 equivalent mpg. The most efficient CNG vehicle comes in at __ mpg? There's no way no how any CNG vehicle is going to be over 50 mpg. CNG is not in the same ballbark.

The problem is the internal combustion engine. It has too many moving parts, too much internal friction. It's an old technology that's served us well but it's time to move on.

The free market is answering the EV vs. CNG question: automakers are rushing new electric vehicles to market but are not rushing CNG. I think it's because the engineers know that electric cars are the next quantum leap in energy efficiency and low cost operation.

I say develop nat gas, nuke, coal, wind, etc. and make lots of electricity and use it to power small urban cars. Farmers, ranchers, big rigs, etc. can continue to use gasoline, diesel and CNG.

if you agree to 1) and 2), then please tell me how the US will signficantly reduce it oil imports *without* using natural gas transportation. <<<<

You might want to read my original post again. Yes, I think US addiction to foreign oil is a problem. Yes I am all for developing domestic natural gas. However, I think it has been demonstrated repeatedly that less energy is wasted if natural gas is used to make electricity, and then that electricity used to power electric cars, than putting NG directly into NG-powered vehicles.

If we are serious about maximizing the use of domestic energy sources, whether it be nuke or NG, then a key component of any strategy will have to be the phase out of the internal combustion engine for passenger cars.

As I've posted on SA before, the problem is that all internal combustion engines are relatively inefficient. Depending on which study you quote, anywhere from 60% to 84% of the energy you put into internal combustion is wasted on heat and internal friction losses. What a shame it would be to take our precious natural gas reserves and waste most of it out of our collective tailpipes.

Electric motors are the most efficient motors known (actually, the bicycle is the most efficient motor known to man, but let's not go there) and approximately 75% of the energy put into an electric motor rolls the car forward, and only 25% is wasted on friction losses.

More efficiency is gained when natural gas is burned for electricity. Modern combined cycle generation plants are very efficient at converting gas to electricity -- combined cycle means the waste heat of the first turbine is captured to make steam and drive a second set of turbines. And so at the end of the day a fleet of electric cars, with electricity generated by nat gas will always trump nat gas cars that burn gas direct. The only barrier that remains is improving battery technology to increase range and decrease charging times.]]>

Electric cars have an advantage of being diversified -- the electricity can come from a portfolio of sources, e.g., nuclear, oil, natural gas, coal, solar, and so on. In addition, the electric motor is the most efficient type of motor available. Internal combustion engines waste 86% of energy as heat and friction. Electric motors only waste 30% on friction losses.

The other advantage of electric cars is we already have a widespread distribution network for electricity. Converting gasoline stations to NG stations would require an expensive and costly retrofitting.]]>

> If the CFTC curbs trading, how will it impact any Energy market?

By making it better. The CFTC position limits will not hamper the legitimate energy professional who needs to hedge or swap; instead, they will be targeted at the purely financial speculators who are trying to make a fast buck and who never intend to actually produce or consume physical energy.

Futures markets are vital in balancing the risks and needs of wholesale producers and consumers of any commodity. It's very important to control and limit the influence of hedge funds and hot money, so they don't distort the market and upset the equilibrium of supply and demand.

It's incredibly obvious that oil and gas hit new highs in 2008 because hedge funds and speculators bid up the prices. This, in turn, encouraged the drillers to overcapitalize, drill and produce at a faster rate than we were consuming. That's why we have a natural gas glut today.]]>
