A Princeton-based working group published its analysis of potential pathways to zero carbon by 2050: the Net Zero America Project.
The Net-Zero America study aims to inform and ground political, business, and societal conversations regarding what it would take for the U.S. to achieve an economy-wide target of net-zero emissions of greenhouse gases by 2050. Achieving this goal, i.e. building an economy that emits no more greenhouse gases into the atmosphere than are permanently removed and stored each year, is essential to halt the buildup of climate-warming gases in the atmosphere and avert costly damages from climate change. This study provides granular guidance on what getting to net-zero really requires and on the actions needed to translate pledges into tangible progress.The Final Report (100MB) / The Final Report Summary.pdf)
The work outlines five distinct technological pathways all of which achieve the 2050 goal
E+ (high electrification)Some major takeaways:
E- (less high electrification)
E- B+ (high biomass)
E+ RE- (high electrification, implementation of wind and solar limited to maximum recent GW/y build)
E+ RE+ (high electriciation, unlimited implementation of wind and solar). This model is the only one that doesn't allow for nuclear power in 2050.
• In all five cost-minimized energy-supply pathways, coal use is essentially eliminated by 2030. • Overall, fossil fuels in the primary energy mix decline by 62% to 100% from 2020 to 2050 across scenarios. Oil and gas decline 56% to 100%.And from here
• In pathways with aggressive electrification (E+, E+RE-, and E+RE+) use of petroleum-derived liquid fuels declines more rapidly than with less-aggressive electrification (E-, E-B+). Natural gas use also declines.
• Oil & gas contributions in 2050 are largest in E+RE-, where fossil, nuclear, and renewables each account for about one-third of primary energy.
• Renewable energy (primarily wind & solar power) accounts for the majority of primary energy in 2050 (60-68%) in the other scenarios, and supply 100% of primary energy in the case of E+RE+.
• Nuclear power is maintained at roughly today’s levels in the least-constrained cases (E+, E-, E-B+), expands significantly when renewable energy deployment is constrained (E+RE-) and is eliminated by 2050 in a 100% renewable energy pathway (E+RE+).
• All pathways rely on large-scale CO2 capture and utilization or storage. In E+RE+, 0.7 Gt/y of CO2 is captured and utilized to synthesis liquid and gaseous hydrocarbons. In all other scenarios, more than 1Gt/y of CO2 is captured with the majority being stored in geologic formations. • Annualized energy spending across the full 30-year transition as a fraction of GDP is similar to spending levels experienced during recent prosperous periods, but all net-zero pathways are much more capital intensive than historical energy sector capital spending.
Direct land use for wind-turbine pads in net-zero scenarios is small, but the (visual) footprint of wind farms is significant. In 2050, total wind farm visual footprint is smallest for E+RE- at ¼ million km2 , or the equivalent of the combined land areas of Illinois and Indiana. The footprint is largest for E+RE+ at 1 million km2 , or the equivalent of Arkansas, Iowa, Kansas, Missouri, Nebraska, and Oklahoma combined. Wind projects are concentrated in the Great Plains, Midwest, and Texas, primarily on crop, pasture, and forested lands.
Land use for solar farms in 2050 is much smaller than the visual footprint of wind farms, but directly impacted lands are greater, ranging from the equivalent of the area of Connecticut for E+RE- to that of Virginia for E+RE+. Solar deployment is greatest in the Northeast and Southeast, and forested lands make up the largest directly impacted land cover type.
nuclear capacity is a more costly option for providing firm power to balance wind and solar variability than other means available in the model for accomplishing this. However, there is significant nuclear expansion in the E+Nu-- and E+Nu--Rate- cases, when capital costs are assumed to reach 1800 $/kW (Figure B26 and Figure B28). Nuclear primarily displaces wind and solar in these cases (Figure B27). These results underline the importance of aggressive nuclear cost reductions if the technology is to play an important role in the transition.submitted by shaokim to nuclear [link] [comments]
2021.12.01 13:25 salcas9490 Possible to Install Doorbell without White Wire?
Long story short, I was installing a Nest Hello doorbell and the little little amount of white wire connector that I had to work with broke off. The way the wire was ran, I cannot get any additional slack. Is there anyway to get the doorbell to work with just the red wire? Maybe a jumper or some sort?

2021.12.01 13:25 A395740849 Can the VBA mandate I sign a release of information for my claim even if I’ve already given them stuff?
I have already submitted my medical records that I deemed relevant to my case.
I just had my C&P exam. It went weird. The examiner said she didn’t see the majority of documents I had submitted. So, I tried my best to summarize them. I told her the name of my private practice as well as my doctor’s name.
I don’t want them having full access to my records that an ROI would entail. Would they mandate I sign one even though I already gave them stuff?

2021.12.01 13:25 SupraLegato The Gavotte is a lively French dance that became popular during the Baroque era when Jean-Baptiste Lully was the lead composer at the court of Louis XIV. This one written by lutenist Silvius Leopold Weiss comes from suite 11 and can also be found in the The Dresden Manuscript (as suite no. 6).

I started noticing that my laptop screen slightly flashes when I type something is a menu or a search bar but it doesn't do that when I plug it into power. Is there any way to make it not flash?
