The United States is undergoing a major shift in how it generates electricity. Over recent years there has been a large shift away from coal and towards gas, wind, and solar. Electricity Transition has released a great story map which illustrates this movement from coal powered electricity to other forms of energy.
Electricity Transition uses a series of animated heat-maps to show the rise of solar and wind energy over recent years. These animated heat-maps are very effective in showing the increasing use of solar and wind energy and also the areas where both methods of electricity generation are being most used.
After viewing the animated tours of electricity generation you can explore the map and data for yourself. A drop-down menu allows you to select to view different sources of energy, including coal, gas, solar, wind, nuclear and hydro. Once you select an energy source you can use the map timeline to view the levels of electricity production from that source over time. If you zoom in on the map you can view the locations of individual power plants. The dot markers that appear when you zoom in are scaled to show the levels of electricity generated. The size of these markers will change as you change the year to reflect the different levels of power generation at plants over the passage of time.
You can also explore America's power supply on the U.S. Power Plants map. U.S. Power Plants is an interactive map showing the locations, size and type of America's electric power plants. The map is a great way to see where different types of power plant are located, how much each type of energy source contributes to the country's power supply and how much each source contributes to America's CO2 emissions.
