Renewable Energy – Wind – Remote Learning –
Esri Geoinquiries: Wind
Activity: Explore potential and developed wind capacity by state, as well as challenges that Texas has faced to develop wind power
Map URL: http://esriurl.com/enviroGeoinquiry11
Engage: What are the typical wind conditions in the US?
Click the map URL link above to open the map.
In the Details pane, click the button, Show Map Legend.
The map shows typical winds across the U.S.
1. Where is the wind speed the highest? What direction is it blowing? [Click the legend to see wind-speed scale. The direction is indicated by the arrow.]
What is your local wind speed and wind direction?
EXPLORE: What is the highest potential capacity for wind power?
Click the checkbox to the left of the layer, Wind Capacity.
3. What states have the highest potential for wind power based on average wind speeds and suitable land available?
Click the markers on the map to view details of various states.
Hover the mouse over the layer name, Wind Capacity. Click the button, Show Table.
In the table, click the column header for Installed Wind Power in 1999. Sort descending.
In the table, click the column header for Installed Wind Power in 2015. Also sort descending
4. Which state has shown the greatest increase?
EXPLAIN: Why does Texas have the greatest wind power capacity?
5. What factors determine wind-power capacity?
Turn on the Texas Wind Farm layer.
6. Based on the placement of the wind turbines, where is the average wind speed the highest?
Wind power measures the energy available in wind. Cube the wind speed to determine wind power.
7. What is the power from an average wind speed of 8 mph and 10 mph?
ELABORATE: How has Texas developed its wind power?
8. Where are the highest power demands?
Click the button, Measure. Choose the Distance button and set units to miles. Hint: See tool tip below for additional help.
9. How far is it from a wind farm (group of linked turbines) to a large city (Dallas or Austin)?
Turn on the CREZ layer.
In 2005, Texas created renewable-energy zones and installed large transmission lines to carry future wind and solar power to urban areas.
10. What patterns do you notice?
Zoom in on wind turbines for site details.
EVALUATE: How can renewable power supply a city’s electricity demands?
Turn on the layer, Map Notes.
Zoom in to Georgetown, TX. Click the pop-up to read about the city’s power plans for 2017.
11. How many wind turbines will Georgetown need to supply 50 percent of their power needs? (Zoom in and click individual wind turbines for detailed energy generation information.)
12. City planners cite cost savings for their choice, but what are other ways that the city could benefit?
How to Use Measure Tool
Click Measure, select the Distance button, and from the drop-down list, choose a unit of measurement.
• On the map, click once to start the measurement, click again to change direction, and double-click to stop measuring.
• Hint: Position the area of interest on the map so that it is not obscured by the Measure window.
How to sort in tables
Tables are only available for certain map layers.
• In the Details pane, point to the desired layer name and click the Show Table button.
• Click the Name column header and choose Sort Ascending or Sort Descending.
