Choosing renewable energy sources to replace fossil fuels is a major challenge. Policymakers must consider issues of geography, economics, and the energy potential of each source.
Part B: Examine the Data Set
One consideration is the amount of water consumed by the cooling rates of different energy sources.
In comparing different energy sources, one important consideration is the amount of water consumed by cooling processes within the plant itself. This data table shows the liters of water consumed per megawatt-hour generated for five different energy sources.
| Generation Technology | Water Consumed in Cooling (L/MWh) |
|---|---|
| Concentrating Solar | 3,180 |
| Fossil Fuels | 1,476 |
| Biomass | 1,476 |
| Nuclear | 2,120 |
| Geothermal | 5,300 |
