var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
.filter('country_lg == "Belgium"');

// Remove duplicate features according to property values.
print('Distinct based on a single property', fc.distinct('fuel1'));
print('Distinct based on two properties', fc.distinct(['fuel1', 'source']));
print('Distinct based on geometry', fc.distinct('.geo'));
