The economy of Tanzania is a lower-middle income economy that is overwhelmingly dependent on agriculture. Tanzania's economy has been transitioning from a planned economy to a market economy since 1985. Although total GDP has increased since these reforms began, GDP per capita dropped sharply at first, and only exceeded the pre-transition figure in around 2007.
Transport in Tanzania includes road, rail, air and maritime networks. The road network is 86,472 kilometres (53,731 mi) long, of which 12,786 kilometres (7,945 mi) is classified as trunk road and 21,105 kilometres (13,114 mi) as regional road. The rail network consists of 3,682 kilometres (2,288 mi) of track. Commuter rail service is in Dar es Salaam only. There are 28 airports, with Julius Nyerere International being the largest and the busiest. Ferries connect Mainland Tanzania with the islands of Zanzibar. Several other ferries are active on the countries' rivers and lakes.
Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels, such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial biowaste. Biofuels are mostly used for transportation, but can also be used for heating and electricity. Biofuels are regarded as a renewable energy source. However, the use of biofuel has been controversial because of the several disadvantages associated with the use of it. These include for example : the "food vs fuel" debate, biofuel production methods being sustainable or not, leading to deforestation and loss of biodiversity or not.
Sustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint by altering their home designs and methods of transportation, energy consumption and diet. Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology. The practice and general philosophy of ecological living closely follows the overall principles of sustainable development.
Kilwa District is one of six administrative districts of Lindi Region in Tanzania. The District covers an area of 15,000 km2 (5,800 sq mi). The district is comparable in size to the land area of the nation state of East Timor. Kilwa district is bordered to the north by Rufiji District in Pwani Region, to the east by the Indian Ocean, to the south by the Lindi District, Nachingwea District together with Ruangwa District, and to the west by the Liwale District. The district borders every other district in Lindi Region except Lindi Municipal District. The district seat (capital) is the town of Kilwa Masoko. The district is named after the medieval Swahili city state of Kilwa Kisiwani. According to the 2012 census, the district has a total population of 190,744.
The energy industry is the totality of all of the industries involved in the production and sale of energy, including fuel extraction, manufacturing, refining and distribution. Modern society consumes large amounts of fuel, and the energy industry is a crucial part of the infrastructure and maintenance of society in almost all countries.
Algaculture is a form of aquaculture involving the farming of species of algae.
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. Net energy import dependency was 40.9% in 2021-22.
Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. The biofuel and food price debate involves wide-ranging views, and is a long-standing, controversial one in the literature. There is disagreement about the significance of the issue, what is causing it, and what can or should be done to remedy the situation. This complexity and uncertainty is due to the large number of impacts and feedback loops that can positively or negatively affect the price system. Moreover, the relative strengths of these positive and negative impacts vary in the short and long terms, and involve delayed effects. The academic side of the debate is also blurred by the use of different economic models and competing forms of statistical analysis.
Electricity in Paraguay comes almost entirely from hydropower. As Paraguay is landlocked and has no significant natural gas reserves, its citizens often burn firewood which contributes to deforestation. The government imports fuel to use, and state-owned Petróleos Paraguayos (Petropar) has a monopoly on all crude oil and petroleum product sales and imports in Paraguay. It operates Paraguay's sole refinery, the 7,500 bbl/d (1,190 m3/d) Villa Elisa facility.
Climate change has received significant scientific, public and political attention in Sweden. In 1896, Swedish chemist Svante Arrhenius was the first scientist to quantify global heating. Sweden has a high energy consumtion per capita, but reducing the dependency on fossil energy has been on the agenda of cabinets of the Governments of Sweden since the 1970s oil crises. In 2014 and 2016, Sweden was ranked #1 in the Global Green Economy Index (GGEI), because the Swedish economy produces relatively low emissions. Sweden has had one of the highest usages of biofuel in Europe and aims at prohibiting new sales of fossil-cars, including hybrid cars, by 2035, and for an energy supply system with zero net atmospheric greenhouse gas emissions by 2045.
Seaweed farming or kelp farming is the practice of cultivating and harvesting seaweed. In its simplest form farmers gather from natural beds, while at the other extreme farmers fully control the crop's life cycle.
Eucheuma, commonly known as sea moss or gusô, is a rhodophyte seaweed that may vary in color. Eucheuma species are used in the production of carrageenan, an ingredient for cosmetics, food processing, and industrial manufacturing, as well as a food source for people in the Philippines, Caribbean and parts of Indonesia and Malaysia. Eucheuma cottonii – which grows in the Caribbean and cultivated in the Philippines – is the particular species known as gusô. Other species include Betaphycus gelatinae, Eucheuma denticulatum, and several species of the genus Kappaphycus, including K. alvarezii. Since the mid-1970s, Kappaphycus and Eucheuma have been a major source for the expansion of the carrageenan industry.
All regions and seasons of Norway are expected to become warmer and wetter due to climate change.
Ubungo I Thermal Power Station, also known as the Ubungo Power Plant, is a natural gas-fueled power plant located in Ubungo of Ubungo District in Dar es Salaam Region of Tanzania. It began commercial operations on 30 July 2008 with an installed capacity of 110 megawatts (150,000 hp).
Environmental issues in the United Arab Emirates (UAE) are caused by the exploitation of natural resources, rapid population growth, and high energy demand. The continuing temperature rise caused by global warming contributes to UAE's water scarcity, drought, rising sea level, and aridity. The countryside of the UAE, characterized with its great arid land, infrequent precipitation, and high temperatures are already facing long-term aridity. This precondition is very vulnerable to the effects of climate change and contributes to worsening water scarcity, quality, and water contamination.
Climate change is having a considerable impact in Malaysia. Increasing temperatures are likely to greatly increase the number of heatwaves occurring annually. Variations in precipitation may increase the frequency of droughts and floods in various local areas. Sea level rise may inundate some coastal areas. These impacts are expected to have numerous environmental and socioeconomic effects, exacerbating existing environmental issues and reinforcing inequality.
The Cook Islands is a net importer of energy, in the form of petroleum products. Total energy consumption was 1,677,278,000 BTU in 2017, of which 811,000,000 was in the form of oil. In 2012 47% of imported oil was used in the transport sector, 30% in aviation, and 27% for electricity generation. Electricity consumption is 31.6 GWh, from 14 MW of installed generation capacity, with most load concentrated on the main island of Rarotonga. Per-capita electricity consumption is approximately two-thirds that in the European Union. Greenhouse gas emissions total 88,810 t per year, or 10.36 t per capita.
Flower Ezekiel Msuya is a Tanzanian phycologist. She specialises in algaculture and integrated aquaculture.
World energy supply and consumption refers to the global primary energy production, energy conversion and trade, and final consumption of energy. Energy can be used in various different forms, as processed fuels or electricity, or for various different purposes, like for transportation or electricity generation. Energy production and consumption are an important part of the economy. A serious problem concerning energy production and consumption is greenhouse gas emissions. Of about 50 billion tonnes worldwide annual total greenhouse gas emissions, 36 billion tonnes of carbon dioxide was emitted due to energy in 2021.
