After watching the presentation, Energy Mix, analyze the changes in consumption and energy mix percentages in the U.S. since 2010 and predict changes in the future.
The table below shows the changes in consumption in the U.S. from 2010 to 2018, from the nine different energy sources discussed in the video.
- Calculate the percentage of total supply in 2010 and 2018.
- Then calculate the percentage change (increase or decrease).
- Next, project the change in the consumption that would occur over the eight years from 2018 to 2026 from these sources if the trends outlined in the presentation were to continue.
- Finally, calculate the percentage of total supply in 2026.
| Energy Source | Quads Used 2010 | % of Total Supply | Quads Used 2018 | % of Total Supply | % Change in Each Source | Projected 2026 Quads Used | % of Total Supply 2026 |
| Solar | 0.130 | 0.949 | |||||
| Nuclear | 8.4 | 8.44 | |||||
| Hydro | 2.5 | 2.69 | |||||
| Wind | 0.92 | 2.5s | |||||
| Geothermal | 0.21 | 0.217 | |||||

| Which energy source has the greatest percent change (increase) from 2010 to 2018? | |
| Which energy source has the greatest percent change (decrease) from 2010 to 2018? | |
| Considering energy consumption trends alone, if your projections are accurate, will nonrenewable or renewable sources fill the majority of energy consumption needs in 2026? | |
| What does Dr. T recommend as a strategy for the energy transition? |
