Re: Actually (none / 0)

So what could be holding back the US government from initiating a massive program to put the entire nation on a wind energy footing?

The oil lobby?

Re: Actually (4.00 / 3)

No, that initiating a massive program to put the entire nation on a wind energy footing would be "socialism".

Re: Actually (none / 0)

As Migeru said. At last year's rate of expansion, it would take something like 75 years for wind to give half of consumption.

How do you figure that?

Re: Actually (none / 0)

Total US consumption is was 4,119 TWh in 2008. (Wind was 55.4 TWh.) Last year 10 GW were added, if we can assume an average capacity factor of 30% (this being the US), they should be good for 26.3 TWh, or an annual increase of market share by around 0.66 percentage points. 48.7/0.66 = 73.8.

Re: Actually (none / 1)

The relevant figure is 26.3TWh/55.4TWh = 47% increase each year (or, x1.5 per year). The model of growth should be logistic and not linear (see Marchetti's curves by Luis de Sousa).

In other words, if in 2009 the installation was 10GW, in 2010 one should expect 15GW, in 2011 22.5GW, and so on, and the rate should slow down only when penetration is a substantial fraction of the total...

Re: Actually (none / 0)

You can expect logistic growth if market conditions are stable. But the development of the US market is anything but regular, more like stop-and-go. This year it should be another massive drop.

Re: Actually (none / 0)

But that's also an argument against your extrapolation.

I guess you can always do a moving average.

Re: Actually (4.00 / 2)

My 'extrapolation' was merely intended to give a picture of what last year's growth rate means relative to total consumption, i.e. that it is not insignificant but even greater growth would be desirable.

Regarding real long-term trends, I would agree that a logistic curve fits both emergence/maturing and phaseout best, but Marchetti curves seem too simplicistic. In Luís's diary, the oil shocks are named as explanation for deviation; on one hand, methinks a lot more reasons can throw development off the Marchetti track (rule changes being one, see wind power in Denmark), on the other hand, I rather doubt that all significant energy modes will peak at the same market penetration level (50%).

Re: Actually (none / 1)

Oh, and the coal and nuclear lobbies are more relevant to wind's expansion (oil is primarily used for transport, gas is primarily used for heating and peak power generation, neither of which is detrimentally affected by wind power).

Re: Actually (4.00 / 3)

The oil lobby is more preventing the US from pursuing a massive program to put in long haul electric rapid freight rail and local electric rail and trolleybus transit ... preventing the US from massive investment in our massive wind resource is more the coal lobby.

Huh, vested interests with massively lucrative cash flows in dead-end industries holding a nation back from moving into the future. So this is what it was like to be Hapsburg Spain.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.

No, being Hapsburg Spain was spending all your blood and treasure fighting wars of religion... Oh, wait!

What's the emoticon for ... (none / 1)

... "hit it on the nose".

I was referring to the other side, the lucrative but ultimately unsustainable mining of the mountain of silver in Mexico and the mountain of silver in Peru ... but the analogies keep spinning on for a while.
