The alternative is to read his book "The Economics of Global Turbulence"

Make of this what you will.

Good thing we have lots of unused rooftops!

And a good thing the actual, physical footprint of wind turbines is orders of magnitude smaller than the area of a wind park.

 

[Masada]

I actually think wind turbines look pretty. :3

 

[Murky]

This is graph is misleading and not taking many things into account. The most important is the land area affected by a nuclear meltdown. I'm sure that's going to be a lot more than that of the solar or wind. Also, the solar could be put on rooftops or low land use locations. The wind turbines can be either offshore or integrated with farmland.

One thing that regularly comes up in wind energy/renewables discussions is the problem of intermittency.

For wind power this becomes a much, much less severe problem when considering scales of >=1000 kilometers

For the West European winter it looks like the total wind power output is below half the average output for less than 10% of the time, with a minimum output of about 20% of the average. (Capacity factor was 21%, average output about 13.5GW)

Should work similar for US or Australia.


For the summer, even continental scale interconnected solar would likely need more capacity, peak output and cycle durability of storage, though.

You must be so very ashamed of yourself.

This is so sad.

 

[Arwon]

well then

I did. And it really belongs, if anywhere, in humor.

 

[Cutlass]

Spoiler :

Source? I find that highly disputable.

 

[Hygro]

Really? It seemed highly plausible to me. What do you find wrong?

 

[Cutlass]

Most of the Northeast and rustbelt is showing a plurality of housing built before 1930. Now maybe they're using the term "plurality" in a way that it wouldn't occur to me to use it. But the suburbs really didn't get their start in a big way until the 1950s. And the national population has tripled since then while at the same time the average household size has gone way down, meaning greater numbers of residential units per capita.

 

[potatokiosk]

Plurality meaning the "1930s and before" category is larger than any decade since. It's quite plausible that, say, 20% of the houses in the northeast were built then.

Census date.
