Assessment of Haiti’s electricity sector
INTRODUCTION:
This report summarizes the current state of the electricity sector in Haiti, to form a
knowledge base from which to subsequently evaluate options for how best to
increase electricity access in Haiti.
Accordingly, this report summarizes the results of an extensive review of the
publicly-available information on the electricity sector in Haiti, supplemented by
targeted interviews with selected individuals known to be knowledgeable about
electricity in Haiti based on their recent involvement in assessing the sector or in
pursuing/supporting development opportunities. [TRUNCATED
Assessing the potential for U.S. utility green bonds
EXECUTIVE SUMMARY:
Bonds are the largest single class of financial instrument across the world’s financial markets.
Recently, a subclass of these bonds, called green bonds, has emerged in the market place.
Green bonds are a type of bond whose proceeds may be used only for certain approved
“green” investments. In exchange for agreeing to invest only in such projects, the bond issuer
obtains some value greater than they would obtain from traditional financing, and are
therefore encouraged to finance and undertake a greater number of green projects. This
unique value may not be recognized in traditional financial accounting. Of course, like any other
capital-raising investment, green bonds enable their issuer to finance a new project that should
increase (or at least maintain) its revenues, profits, and cash flow.
The utility sector was the second largest issuer of green bonds in 2017, accounting for $26.2
billion dollars’ worth of green bond issuance globally. These were primarily issued to finance
renewable energy projects, a class of projects that makes the utility sector one of the most
logical for deployment of green bonds.
While choosing to issue green bonds does not seem to have any price advantage over regular
bonds in the market, green bonds can provide other benefits. These benefits may include
reputation effects, better treatment in secondary markets, and other intangibles (See Table ES1)

NUMERICAL MODELING OF DEFORMATION WITHIN RESTRAINING BENDS AND THE IMPLICATIONS FOR THE SEISMIC HAZARD OF THE SAN GORGONIO PASS REGION, SOUTHERN CALIFORNIA
Assessment of seismic hazards in southern California may be improved with more accurate characterization of active geometry, stress state, and slip rates along the active San Andreas fault strands within the San Gorgonio Pass region. For example, on-going debate centers on the activity and geometry of the Mill Creek and Mission Creek strands. Calculated misfits of model slip rates to geologic slip rates for six alternative active fault configuration models through the San Gorgonio Pass reveal two best-fitting models, both of which fit many but not all available geologic slip rates. Disagreement between the model and geologic slip rates indicate where the model fault geometry is kinematically incompatible with the interpreted geologic slip rate, suggesting that our current knowledge of the fault configuration and/or slip rates may be inaccurate.
Focal mechanism of microseismicity can estimate stress state; however, within the San Bernardino basin, some focal mechanisms show slip that is inconsistent with the interseismic strike-slip loading of the region. We show that deep creep along the nearby northern San Jacinto fault can account for this discrepancy. Consequently, if local stresses are estimated using these focal mechanisms, the resulting information about fault loading may be inaccurate. We also use another way to estimate the present-day, by calculating evolved fault tractions along a portion of the San Andreas fault using the time since last earthquake, fault stressing rates (which account for fault interaction), and co-seismic models of the impact of recent nearby earthquakes. Because this method considers the loading history of each fault, the evolved tractions differ significantly from the resolved regional tractions and can provide more accurate initial conditions for dynamic rupture models within regions of complex fault geometry.
Numerical models of restraining bends in a viscoelastic material have implications for how we model the Earth’s crust. Deforming the model at faster velocities decreases the amount of visco-relaxation, allowing the model to behave more elastically. Viscoelastic models allow for velocity-dependent deformation, which could improve our understanding of crustal deformation, especially within complex fault systems
Long-term U.S transportation electricity use considering the effect of autonomous-vehicles: Estimates & policy observations
In this paper, we model three layers of transportation disruption – first electrification, then autonomy, and finally sharing and pooling – in order to project transportation electricity demand and greenhouse gas emissions in the United States to 2050. Using an expanded kaya identity framework, we model vehicle stock, energy intensity, and vehicle miles traveled, progressively considering the effects of each of these three disruptions. We find that electricity use from light duty vehicle transport will likely be in the 570–1140 TWh range, 13–26%, respectively, of total electricity demand in 2050. Depending on the pace at which the electric sector decarbonizes, this increase in electric demand could correspond to a decrease in LDV greenhouse gas emissions of up to 80%. In the near term, rapid and complete transport electrification with a carbon-free grid should remain the cornerstones of transport decarbonization policy. However, long-term policy should also aim to mitigate autonomous vehicles’ potential to increase driving mileage, urban and suburban sprawl, and traffic congestion while incentivizing potential energy efficiency improvements through both better system management and the lightweighting of an accident-free vehicle fleet
Cities and climate change: Strategic options for philanthropic support
Now, more than ever, cities are at the front lines of U.S. climate action. As national action stalls,
there is still a daunting amount to be done in reducing human-generated climate emissions.
Fortunately, this report comes in the wake of a groundswell of initiatives to engage on climate
change by cities, countries, and states across the U.S. Several important and thorough reports
on the types of mitigation actions cities can take have recently been released. We already have
examples of cities taking significant leadership roles in reducing their own climate emissions,
from New York and Boston to Austin, Boulder, and Los Angeles - yet U.S. climate emissions
continue to rise, and cities have an outsized role to play.
The purpose of this project is to review current U.S. city climate activities in order to identify
areas where additional investment by foundations could help accelerate city action to reduce
urban greenhouse gas emissions. The focus of the inquiry is on aggressive actions cities can take
that significantly increase their “level of ambition” to achieve emissions reductions on an
accelerated timetable. City strategies on climate adaptation are not encompassed in this
project. [TRUNCATED
Sustainable Tourism Recommendations: Southern Maine
Through the lens of sustainable tourism one can assess the impacts and benefits of economic, environmental and social variables on communities and the landscape in order to manage them and create responsible tourism opportunities. In this poster, data from economic development and tourism practitioners in the Greater Portland region is aggregated into suggested tourism policy and planning strategies for Southern Maine
Life Skills Development in Youth: Impact Research in Action
Developing life skills is a key element of 4-H programming, but research on the impact of 4-H on life skill development is minimal. 4-H alumni and volunteers were surveyed to explore the question Does involvement in 4-H Youth Development programs help youth learn and use specific life skills? 4-H alumni identified life skills learned through 4-H participation from a list of choices and in an open-ended format. Volunteers agreed that life skills were learned, although their assessment of specific skills differed from that of alumni. Findings indicate that long-term impacts of 4-H membership exist and can be measured
The Roles of Non-Cognitive and Cognitive Skills in the Life Course Development of Adult Health Inequalities
Previous research has suggested that greater cognitive skill is protective against the development of socio-economic health inequalities across the life course, but the relative role of non-cognitive skills has been less investigated in this context. Using the prospective UK 1958 National Child Development Study (N = 18,558), higher factor scores for adolescent non-cognitive skills (NCS; i.e. a combination of work habits and pro-social behaviours) and mean cognitive skill (CS) at age 16 were examined with a path analysis model in relation to socioeconomic status (SES) across the life course (at ages 16, 33 and 50) and poor self-reported health at age 50. Adjusting for adolescent NCS explained over a third of the association between education and health, but the path between social class at age 50 and health was unaffected. Adjustment for CS explained larger proportions of the paths to adult health inequalities; and paths between CS and SES across the life course were stronger than the same paths with NCS. However, NCS was still independently associated with paths to later health inequalities in fully adjusted models, and both types of skill had equivalent inverse direct effects with poor health (OR: 0.82 [95% CI 0.73,0.93] vs 0.83 [0.72,0.96], respectively). Since NCS retained independent associations with SES and health across the life course, they could be a target for policies aimed at ameliorating the production of health inequalities for a wide range of children, regardless of their cognitive skill
