The initial map shows the percent change in total electricity consumed by state from 1960 to 2021.
Each of the above highlighted attributes can be changed in the grey sidebar to the left of the map. Click the Update Map button to refresh the map based on your selections.
Click a location on the map and scroll down to see how electricity consumption changes over time at that location. Click on the tabs to view additional information. Click on the magnifying glass icon on the right side of the map to search for a location.
Electricity over time (left) shows the electricity consumed over time for the selected energy type and location.
All types of energy over time (right) shows all energy types over time for the selected location.
Energy Mix shows the percentage of electricity generated by energy type for the selected location (top) and nationally (bottom) in the start year (left) and end year (right).
Over which time periods were there significant trends? shows the slope (more electricity is positive and less electricity is negative) and p-value (how significant is the trend) for different time periods with 10+ years of data. This shows how consistent changes in electricity have been over time and helps compensate for when a time period starts or ends in extremity. Highlighted cells are for the selected start year (row).
Slope (Trillion Btu / yr):
| Slope ≥ 10,000 | -10,000 < Slope < 10,000 | Slope ≤ -10,000 |
P-value:
| Pval > 0.10 | 0.05 < Pval ≤ 0.10 | Pval ≤ 0.05 |
Energy is needed produce electricity for everyday life. At the same time, water is needed to produce electricity and the volume of water needed depends on the energy source. Electricity can be produced from fossil fuels (such as coal and natural gas), by nuclear power plants, and through renewable energy such as solar, wind, and hydropower. Hydropower is the largest renewable energy source for electricity generation in the U.S. Hydropower grew steadily during the big dam building era of the 1950s and 1960s prior to leveling off. Hydropower is affected by the availability and timing of water flowing into reservoirs, as well as the capacity of the reservoir to release water to meet regulatory requirements such as minimum flows or the Endangered Species Act.
