All significant aspects of the energy stream were estimated. land-use figure is a Bloomberg News analysis of current land-use estimates. (Sources and additional information for acreage estimates are detailed in the next section) Energy Information Administration, Department of Homeland Security, U.S. Uses 81 Million Acres to Power Its Economy Estimates are for current infrastructure and do not project future efficiency advances since study dates. Medians incorporate capacity factors and account for the total footprint, including surface area used in additional infrastructure, not just the power plant. Estimates are median values of 177 different density studies.

This will include sources and notes to describe the Bloomberg News analysis of current energy land use, as well as additional notes to further explain how maps depict Princeton University’s Net-Zero America project.Ĭhart: Power Densities: Renewables Need More Space The following section will describe sources and additional information, where applicable, for each visualization in the story. will need to rethink land use for an emissions-free future. think tank Carbon Tracker concluded that renewables actually require less space than fossil fuels. could take to eliminate greenhouse gases, and there’s little consensus among researchers regarding how much land the U.S. Both pathways identify infrastructure and technological challenges and quantify health and environmental benefits, as well as necessary capital investment To show how that land-use picture could change by 2050, Bloomberg considered two of five detailed scenarios outlined by Princeton University’s Net-Zero America project-one requiring the least amount of land and one that calls for the most. Departments of Energy, Interior and Agriculture and the Nuclear Regulatory Commission to estimate how much land the U.S. may need to meet Biden’s goals, Bloomberg News first analyzed data from the U.S. ![]() Power Densities: Renewables Need More Space would need up to four additional South Dakotas to develop enough clean power to run all the electric vehicles, factories and more. By 2050, when Biden wants the entire economy to be carbon free, the U.S. Expanding wind and solar by 10% annually until 2030 would require a chunk of land equal to the state of South Dakota, according to Princeton University estimates and an analysis by Bloomberg News. needs to increase its carbon-free capacity by at least 150%. To fulfill his vision of an emission-free grid by 2035, the U.S. A natural-gas power plant with that same generating capacity could fit onto a single city block.Īchieving Biden’s goal will require aggressively building more wind and solar farms, in many cases combined with giant batteries. A 200-megawatt wind farm, for instance, might require spreading turbines over 13 square miles (36 square kilometres). Wind farms, solar installations and other forms of clean power tend to take up more space on a per-watt basis than their fossil-fuel-burning brethren. The goal will require sweeping changes in the power generation, transportation and manufacturing sectors. greenhouse gas emissions in half by 2030. At his international climate summit in April, President Joe Biden vowed to cut U.S.
