A detailed description of windmills.

No carbon footprint here.

I enjoyed seeing this recent review of windmills.  I’ve always been fascinated by the technologies and struck by large wind farms in central northwest Texas.  A couple of counties there are trying to out do each other with respect to the total energy output.  The devices are beautiful to watch.  We picked up a low frequency ground roll from them also.

Enjoy the article.  Here is the link.

Here is a link to a nice description of Texas Wind Energy.

The wiki page for wind power in Texas can be found here.

A beautiful idea.

The state has been classified by Wind Power potential.  An example can be found here.

NREL (National Renewable Energy Laboratory) has produced a GIS-based tool for dynamic maps, which include wind resource maps.  Here is their website.

A higher resolution tool is available at the Wind and Hydropower Technologies Program site of the U.S. Department of Energy (DOE), Energy Efficiency and Renewable Energy program.  Here is their site related to wind power.

A useful handbook, earlier published by the DOE, “Wind Energy Resource Atlas of the United States” can be found here. It is somewhat dated, but a useful reference.

The economic situation is darkly reviewed below.  I’m not sure about the comparisons drawn, but there is a nice collection of economic data presented.

Here is a link to the PDF of the discussion (including all figures).

The economy is transitioning between a cheap energy economy to an expensive energy economy.  Unfortunately global climate change, scarce drinkable water resources, and population increase towards a limiting planet carrying capacity, are simultaneously unfolding.  This human cultural, economic and political transition, which will occur over the next 20 years, will be a key component of human history.  I have no doubt  it will rank with the transition from the dark ages to the age of reason or the fall of the Roman Empire, depending on how it all works out.

Happy Halloween!
