As of 2017, among all the countries in the Americas, Haiti is producing the least energy. Less than a quarter of the country has electric coverage. Most regions of Haiti that do have energy are powered by generators. These generators are often expensive and produce a lot of pollution. The areas that do get electricity experience power cuts on a daily basis, and some areas are limited to 12 hours of electricity a day. Electricity is provided by a small number of independent companies: Sogener, E-power, and Haytrac. There is no national electricity grid within the country. The most common source of energy used is wood, along with charcoal. In Haiti, about 4 million metric tons of wood products are consumed yearly. Like charcoal and wood, petroleum is also an important source of energy for Haiti. Since Haiti cannot produce its own fuel, all fuel is imported. Yearly, around 691,000 tons of oil is imported into the country.
