英文摘要	Updated results Due to error in the spatial analysis code, not all pixels were properly masked from renewable energy suitability when deriving technical potential according to the sector-specific methodology we employed (supplementary data section 4, available online at stacks. iop.org/ERL/14/109501/mmedia). Specifically, not all pixels with elevation >2000m were properly masked from the wind suitability map, and similarly, not all pixels with cropland >20% (within a 3×?3 window) or slope >5% were excluded from the concentrated solar power (csp) and utility-scaled photovoltaic (pv) suitability maps before calculating technical potential. All other masking procedures were correct and none of the above mentioned changes affected rooftop technical potential estimates. While correcting these errors resulted in lower estimates of renewable energy potential on converted lands for each sector and collectively (max TWh map), there were no changes to the study's conclusions. We have updated the relevant main manuscript and SI text, figures, and data tables as detailed below and provided online. Updated main text Abstract Line ff7: The world has 17 times the required energy targets on converted lands, and most countries, including the top ten emitters, can meet the Paris agreement goals. 3. Results and discussion Line ff3: After removing areas unsuitable for renewable energy development (e.g. areas that are protected, have low energy resource value, contain biophysical constraints, or experience high multiuse competition; see supplementary information), we estimated that 151 055 TWh technical potential are available on converted lands (figure 2(A)) from wind (11 849 TWh, figure S3A, supplementary data S2) and solar (CSP: 59 995 TWh, PV: 76 090 TWh, and rooftop PV: 3121 TWh, figures S3(B), (C), supplementary data S2). With additional gains from retrofitting of existing dams (134 TWh) and repurposing of non-hydroelectric dams (88 TWh), a total of 151 277 TWh are available. While nine countries (Bulgaria, Macedonia, Moldova, Romania, Singapore, Slovakia, South Korea, Thailand, Trinidad and Tobago) cannot meet their NDC commitments on converted lands (figure 2(B)), the total global TWh available on converted lands is 17 times larger than the total NDC energy targets (9017 TWh; supplementary data S2). Line ff36: While we recognize that these demand projections may be over-optimistic in allocation of all consumer sectors' demands to renewable energy and have other limitations, we encouragingly found that current converted lands have 1.6 times the amount of technical potential (166 686 TWh) than the 2050 projected demands (103 716TWh). Line ff56: Despite the encouraging global and regional results, country-specific analyses reveal that 68 countries are unable to meet 2050 energy demands solely on converted lands, including five of the top ten GHG emitters (China, EU28, Japan, India, and Indonesia; supplementary data S2, figures 2(B), (C)). Line ff149: We post hoc explored this overestimation potential using global datasets for existing CSP and wind turbines (no global data were available for PV) and found such overestimation is marginal at best, with existing CSP and wind installations respectively accounting for 0.001% and 0.125% of the total estimated renewable energy on converted lands (see details in supplementary information section 4).
