  description: 'The [HREA](http://www-personal.umich.edu/~brianmin/HREA/index.html)
    project aims to provide open access to new indicators of electricity access and
    reliability across the world. Leveraging satellite imagery with computational
    methods, these high-resolution data provide new tools to track progress toward
    reliable and sustainable energy access across the world.


    This dataset includes settlement-level measures of electricity access, reliability,
    and usage for 89 nations, derived from nightly VIIRS satellite imagery. Specifically,
    this dataset provides the following annual values at country-level granularity:


    1. **Access**: Predicted likelihood that a settlement is electrified, based on
    night-by-night comparisons of each settlement against matched uninhabited areas
    over a calendar year.


    2. **Reliability**: Proportion of nights a settlement is statistically brighter
    than matched uninhabited areas. Areas with more frequent power outages or service
    interruptions have lower rates.


    3. **Usage**: Higher levels of brightness indicate more robust usage of outdoor
    lighting, which is highly correlated with overall energy consumption.


    4. **Nighttime Lights**: Annual composites of VIIRS nighttime light output.
