Zoom-in and check out how many turbines are in your areaThe U.S. Geological Survey, better known as USGS, aims to provide "reliable scientific information to describe and understand the Earth and manage water, biological, energy, and mineral resources." Part of that mission includes keeping track of all kinds of things that are on U.S. ground, including wind turbines. Using high-resolution aerial imagery and data from the Federal Aviation Administration (FAA), they created a very cool interactive map that shows around 47,000 ground-based wind turbines!
Above you can see the map of the US all the way zoomed out, but you can also zoom in and see individual turbines. Here's an example of a wind farm in Iowa (notice all the straight lines):
And here's a very different-looking wind farm close to San Francisco:
Let's not forget Alaska:
Here's the USGS's description of this project:
The purpose of this project is to provide a publicly available, spatially referenced, national dataset of onshore wind turbine locations and their corresponding facility information and turbine technical specifications. The project compiled wind turbine information from the Federal Aviation Administration (FAA) Digital Obstacle File, as well as other manually digitized turbine locations.
Verification of the turbine position was done by visual interpretation using high-resolution aerial imagery. Wind farm facility location data from various sources were collected and used to search for and digitize turbines. The database, current through July 2013, has ~47,000 wind turbine records. These have been collected, digitized, positionally verified, and internally reviewed as part of the USGS Fundamental Science Practices. For more information about the dataset, see USGS DS-817.
Above is a big cluster of wind power around Iowa.
This one shows part of Texas.
And this is the surroundings of San Francisco in California.
