Three primary energy sources make up the energy mix in Guinea: fossil biomass, oil and hydropower. Biomass (firewood and charcoal) makes the largest contribution in primary energy consumption. [1] It is locally produced, while Guinea imports all the petroleum products it needs. [1] The potential for hydroelectric power generation is high, but largely untapped. Electricity is not available to a high percentage of Guineans, especially in rural areas, and service is intermittent, even in the capital city of Conakry.
The estimated 2012 national consumption was 903 million kWh. [2] Consumption per individual was less than the equivalent of half a ton of petroleum, broken down into 80% from biomass, 18% from hydrocarbons and 2% from electricity. [3]
At the national level, 34% of the population have access to electricity. In rural areas where 8.1 million people reside, 7% have access to electricity. [4]
In 1995, firewood was by far the greatest source of energy, accounting for 85%. [5] In 2008, biomass accounted for 89%. [1] According to a 2012 International Monetary Fund paper, over 74% of households use firewood for cooking. [3] 23% use charcoal. [3]
The Electricité Nationale de Guinée (National Electricity Company of Guinea) is responsible for all production and distribution of electricity in the country. [6] However, service is poor; even households in Conakry are served less than 12 hours a day. [3] According to The World Factbook , as of 2013, only 53% of urban areas and 11% of rural areas had access to electricity, leaving 8.7 million people without it. [2] There is also a sharp east-west divide: west of the Ouré-Kaba-Tougué axis, nearly 30% had electricity, but that figure dropped to barely over 5% to the east. [3]
In 2013, electricity production was an estimated 971 million kWh. [2] In 2012, an estimated 67.8% of the electricity was obtained from fossil fuel and the remainder from hydroelectric plants. [2] The country has considerable hydropower potential - about 6000 megawatts (MW) or 19,300 GWh annually - but taps only a small percentage of it. [1] [5] [3]
The country is currently engaged in interconnection projects such as the sub-regional Organisation pour la mise en valeur du fleuve Sénégal (Sénégal River Basin Development Organization), [7] Organisation pour la mise en valeur du fleuve Gambie (Gambia River Basin Development Organization) [7] and West African Power Pool. [8]
The country has no known reserves. [2] It imported an estimated 9,089 bbl/day in 2012. [2]
Guinea is believed to have substantial potential for renewable energy. Potential resources for hydroelectricity is estimated at 4,740 MW. [9] Government policy seeks to improve energy efficiency, increase the share of renewables, and cut local electricity tariffs. [9]
The country plans to install off-grid solar systems in rural areas to improve access to electricity. [4] The mini-grids will have capacities between 10 kilowatts to 10 MW. [10]
India is the third largest producer of electricity in the world. During the fiscal year (FY) 2021–22, the total electricity generation in the country was 1,719 TWh, of which 1,484 TWh was generated by utilities.
The energy policy of India is to increase the locally produced energy in India and reduce energy poverty, with more focus on developing alternative sources of energy, particularly nuclear, solar and wind energy. India attained 63% overall energy self-sufficiency in 2017.
In Honduras, there is an important potential of untapped indigenous renewable energy resources. Due to the variability of high oil prices and declining renewable infrastructure costs, such resources could be developed at competitive prices.
The electricity sector in Colombia is dominated by large hydropower generation (65%) and thermal generation (35%). Despite the country's large potential in new renewable energy technologies, this potential has been barely tapped. A 2001 law designed to promote alternative energies lacks certain key provisions to achieve this objective, such as feed-in tariffs, and has had little impact so far. Large hydropower and thermal plants dominate the current expansion plans. The construction of a transmission line with Panama, which will link Colombia with Central America, is underway.
The electricity sector in Argentina constitutes the third largest power market in Latin America. It relies mostly on thermal generation and hydropower generation (36%). The prevailing natural gas-fired thermal generation is at risk due to the uncertainty about future gas supply.
The largely government owned electricity sector in Haiti referred to as Électricité d'Haïti (ED'H for "Haiti Electric Utility", faced a deep crisis characterized by dramatic shortages and the lowest coverage of electricity in the Western Hemisphere in 2006. with only about 38.5% of the population having regular access to electricity. In addition, Haiti's large share of thermal generation makes the country especially vulnerable to rising and unstable oil prices.
Brazil has the largest electricity sector in Latin America. Its capacity at the end of 2021 was 181,532 MW. The installed capacity grew from 11,000 MW in 1970 with an average yearly growth of 5.8% per year. Brazil has the largest capacity for water storage in the world, being dependent on hydroelectricity generation capacity, which meets over 60% of its electricity demand. The national grid runs at 60 Hz and is powered 83% from renewable sources. This dependence on hydropower makes Brazil vulnerable to power supply shortages in drought years, as was demonstrated by the 2001–2002 energy crisis.
The Democratic Republic of the Congo was a net energy exporter in 2008. Most energy was consumed domestically in 2008. According to the IEA statistics the energy export was in 2008 small and less than from the Republic of Congo. 2010 population figures were 3.8 million for the RC compared to CDR 67.8 Million.
The electricity sector of Uruguay has traditionally been based on domestic hydropower along with thermal power plants, and reliant on imports from Argentina and Brazil at times of peak demand. Over the last 10 years, investments in renewable energy sources such as wind power and solar power allowed the country to cover in early 2016 94.5% of its electricity needs with renewable energy sources.
Renewable energy in Nepal is a sector that is rapidly developing in Nepal. While Nepal mainly relies on burning biomass for its energy needs, solar and wind power is being seen as an important supplement to solve its energy crisis. The most common form of renewable energy in Nepal is hydroelectricity.
Renewable energy in Afghanistan includes biomass, geothermal, hydropower, solar, and wind power. Afghanistan is a landlocked country surrounded by five other countries. With a population of less than 35 million people, it is one of the lowest energy consuming countries in relation to a global standing. It holds a spot as one of the countries with a smaller ecological footprint. Hydropower is currently the main source of renewable energy due to Afghanistan's geographical location. Its large mountainous environment facilitates the siting of hydroelectric dams and other facets of hydro energy.
Nepal had a total primary energy supply (TPES) of 10.29 Mtoe in 2012. Electricity consumption was 3.57 TWh. Most of this primary energy represents solid biofuels used in the residential sector . About 23% of the electricity is imported, with the rest almost completely supplied by hydroelectricity. Nepal also exports hydroelectricity to India in the wet season.
Myanmar had a total primary energy supply (TPES) of 16.57 Mtoe in 2013. Electricity consumption was 8.71 TWh. 65% of the primary energy supply consists of biomass energy, used almost exclusively (97%) in the residential sector. Myanmar’s energy consumption per capita is one of the lowest in Southeast Asia due to the low electrification rate and a widespread poverty. An estimated 65% of the population is not connected to the national grid. Energy consumption is growing rapidly, however, with an average annual growth rate of 3.3% from 2000 to 2007.
Renewable energy in South Africa is energy generated in South Africa from renewable resources, those that naturally replenish themselves—such as sunlight, wind, tides, waves, rain, biomass, and geothermal heat. Renewable energy focuses on four core areas: electricity generation, air and water heating/cooling, transportation, and rural energy services. The energy sector in South Africa is an important component of global energy regimes due to the country's innovation and advances in renewable energy. South Africa's greenhouse gas (GHG) emissions is ranked as moderate and its per capita emission rate is higher than the global average. Energy demand within the country is expected to rise steadily and double by 2025.
Vietnam utilizes four main sources of renewable energy: hydroelectricity, wind power, solar power and biomass. By the end of 2018, hydropower was the largest source of renewable energy, contributing about 40% to the total national electricity capacity. In 2020, wind and solar had a combined share of 10% of the country's electrical generation, already meeting the government's 2030 goal, suggesting future displacement of growth of coal capacity. By the end of 2020, the total installed capacity of solar and wind power had reached over 17 GW. Over 25% of total power capacity is from variable renewable energy sources. The commercial biomass electricity generation is currently slow and limited to valorizing bagasse only, but the stream of forest products, agricultural and municipal waste is increasing. The government is studying a renewable portfolio standard that could promote this energy source.
Burning of charcoal and wood fuel provides approximately 94 percent of the energy in Malawi. Much of the renewable hydroelectric potential of the country is untapped. As per 2018 Population and Housing Census, the national electrification rate in Malawi was 10%, with 37% of the urban population and only 2% of the rural population having access to electricity.
Zambia is potentially self-sufficient in sources of electricity, coal, biomass and renewable energy. The only energy source where the country is not self-sufficient is petroleum energy. Many of the sources of energy where the country is self-sufficient are largely unexploited. As of 2017, the country's electricity generating capacity stood at 1,901 megawatts.
Koukoutamba Hydroelectric Power Station is a planned 294 megawatts (394,000 hp) hydroelectric power station, across the Bafing River, a tributary of the Senegal River, in Guinea. The power station is under development by the Organisation pour la mise en valeur du fleuve Sénégal (OMVS),. OMVS will sell the electricity to the four member electricity utility companies of the organization. Sinohydro, a hydropower engineering and construction company, owned by the Chinese state, was awarded the engineering, procurement and construction (EPC) contract. The US$812 million project is funded by the Exim Bank of China.
Ethiopia has abundant resources that can generate 60,000 MW electricity from hydroelectric, wind, solar and geothermal sources in the next 10 years. The electrification process causes GDP growth and high public demand for 110 million of its population. On total, Ethiopia produces 11 billion kWh from all facilities and exports other resources like natural gas or crude oil.
