  Hong Kong generates most of its electricity locally. The vast majority of this energy comes from fossil fuels, with 46% from coal and 47% from petroleum. The rest is from other imports, including nuclear energy generated in mainland China. Renewable sources account for a negligible amount of energy generated for the territory. Small-scale wind-power sources have been developed, and a small number of private homes and public buildings have installed solar panels.
  
  With few natural lakes and rivers, high population density, inaccessible groundwater sources, and extremely seasonal rainfall, the territory does not have a reliable source of freshwater. The Dongjiang River in Guangdong supplies 70% of the city's water, and the remaining demand is filled by harvesting rainwater. Toilets in most built-up areas of the territory flush with seawater, greatly reducing freshwater use.
  
  Broadband Internet access is widely available, with 92.6% of households connected. Connections over fibre-optic infrastructure are increasingly prevalent, contributing to the high regional average connection speed of 21.9 Mbit/s (the world's fourth-fastest). Mobile-phone use is ubiquitous; there are more than 18 million mobile-phone accounts, more than double the territory's population.
