In Guyana, the areas outside of the coastal plain are referred to as hinterland. Approximately twenty percent of the Guyanese population live in the hinterland. The population mostly consists of Amerindian communities who have little access to modern energy services such as electricity, light and modern fuels for cooking and transportation. This situation contrasts with the coastal plain, where there is access to the electricity grid. Several initiatives are in place to improve energy services in the hinterland.
According to a 2013 survey of Amerindian villages done by the Inter-American Development Bank, "the most common source of electricity was a government-donated 65kW photovoltaic panel, and the second most common was a village-operated diesel generator. A few households reported having personal generators and privately purchased photovoltaic panels. In most villages, electric service is intermittent, provided for only four to six hours per day." St. Ignatius is an exception, as the community receives electricity from the Lethem grid. [1]
Photovoltaic systems can be Solar Home Systems, installations for a specific application (like a water pump or freezer) or community or mini-grids serving multiple users.
No public records exist on private solar home systems in use in Guyana. However, several development projects have comprising solar home system (SHS) installations or portable systems (Pico-PV) for small lights etc. have been carried out in Hinterland villages. These projects typically use a one size fits all approach to serve a large number of beneficiaries. Solar systems for community use or specific consumers are generally larger in size, and designed specifically to meet the electric load.
The Institute of Applied Science and Technology has been investigating rice husk for combustion, and vegetable oils (palm, coconut, jathropa, wastes) for biodiesel production, [2] with large scale palm oil based production facilities in Wauna, Region 1. Development of a national Agro-Energy Policy has been reported, [3] but information has not been updated since 2008.
The GEA reports small scale biogas production at 5 sites [4] in Georgetown, Linden and Berbice, using mostly low-cost polyethylene-film tube digesters of plug-flow digesters. Many have been supported by IDB and the Institute of Private Enterprise Development. Pay-back periods of 3-7 months have been reported. A similar digester has been built in Bina Hill, but this digester is currently not operational.
The Government of Guyana implemented this programme with loan support from the Inter-American Development Bank (IDB) in 2004, to make improvements for Guyana Power and Light, and a hinterland energy component, using Solar Home Systems and community-based systems for schools to provide community and household access to electricity. The systems in Yarakita, Capoey, Kurukubaru and Muritaro comprised a 125 W monocrystalline panel and flooded lead acid battery. The schools in these villages received 250 W system with inverter, 8x25W bulbs and 120 V outlets. Another 12 villages received a total of 1200 SHS with 65 W panels and maintenance-free AGM battery, and one 260 W system for the school. Wind speed measurements were carried out in Orealla, Jawalla, Campbelletown and Yupukari, but wind power potential was found to be insufficient [4]
This project was funded by CIDA, implemented jointly by the Latin American Energy Organisation (OLADE) and the University of Calgary School of Business. The Guyana Energy Agency was the national supporting agency. In the village of Wowetta the following were installed; 49 Solar Home Systems (40W MC Kyocera panel, 92Ah Deka AGM battery, 8 Amp Steca controller, one 7W and one 15W CFL 12V lightbulb), a freezer for the village shop (SunDanzer 24V freezer, 2x130W Kyocera panels, a 15 Amp Steca controller and two 12V lightbulbs), a Lorenz submersible water pump for irrigation of vegetable garden (four 85W panels, Lorenz 200 pump controller), an electric 110 V cassava mill powered by a diesel generator, and a joinery shop. A field visit in May 2011 showed that the SHS and solar freezer were working well, but the water pump was defective. In addition, due to several overcast days the freezer was temporarily emptied due to insufficient cooling.
The United Nations Development Programme and Office of Prime Minister installed 3 PV systems for income generation, one in Wauna to support a peanut processing business, one in Kato for a vaccine freezer and battery charging service and one in Orealla to support Fruit Cheese production. Also, efficient woodstoves were introduced in Orealla and Kato to reduce firewood consumption and respiratory illnesses from smoke inhalation. Wind measurement was carried out in Paramakatoi, but proved insufficient for wind power generation In Kato an opportunity was identified to use small hydro-power at the Chiung River to operate a water pump for irrigation purposes, and a prefeasibility study was carried out. In 2011 the hydro-power option is pursued by OPM and under EU support to provide the school in Kato with electricity and irrigation for the nearby fields.
The UNDP further expanded on this in 2011-2012 and 2013–2015 by a needs assessment survey carried out in Regions 1 and 7 to identify specific energy needs and potential energy sources.
In 2009 the Guyana Energy Agency and Office of Prime Minister in collaboration with Ministry of Amerindian Affairs provided 1000 portable solar light kits to 19 Villages in Regions 1,2,7,8 and 9. The kit consists of a 15W panel, a charge control cabinet containing a 20Ah battery and three 11W CFL light bulbs. [4] In 2011 another 100 solar light kits were procured, with new design and LED light bulbs.
In 2011 the government made plans to invest more on distributed PV technology by deploying 11.000 Solar Home Systems (65W) [5] [6] to mostly Amerindian Hinterland and riverine communities as part of the Low Carbon Development Strategy (LCDS). The systems will be equipped with maintenance-free AGM batteries. Due to delays in accessing funding by the Guyana REDD+ Investment Fund (GRIF) the acquired equipment will be paid from the national treasury and the government will seek retroactive financing. [5]
The project will also include training the communities to install and maintain their systems.
This German foundation Eerepami Regenwaldstiftung has carried out several renewable energy initiatives in Guyana. In Bina Hill and Shell Beach 1 kW PV systems have been installed, and the Bina Hill system will later be extended to 11 kW. In Annai and Agatash a set of 100 solar lights have been distributed. The foundation also encourages other hinterland activities and volunteering.
After identifying the lack of knowledge on PV technology the Peace Corps has initiated efforts to provide engineering support to specific locations in the Hinterland as well as prepare training for community volunteers in 2011. Support consisted of 2 volunteers stationed in Region 1 and Region 9.
Mobile operators (Digicel and GTT) are expanding their coverage to off-grid areas and thus require electricity for the base stations. As conventional diesel generators face maintenance and fuel cost issues and the price of PV equipment is declining, it is envisaged that mobile base stations will be powered by PV systems. Digicel has already installed PV power systems in the villages of Wakapau, Kwebanna, Red Hill and Matthews Ridge, 58 miles, Mahdia Trail, Mahdia, Port Kaituma and Mabaruma. To support local communities and improve the mobile communication potential a phone charging service is provided to the communities free of charge.
Several private users and tourism businesses have installed renewable energy systems in the Hinterland. PV electricity, typically using diesel backup, is in use at least at Iwokrama Field Station, Surama Ecolodge, Gamell's Back Shop (Kumaka), Adel's Eco-Resort, Arrow Point and Karinambo.
The stalled Amaila Falls Hydro Energy project was projected to create electrical power is 165MW, mainly for mining.
The Caricom Renewable Energy Development Programme (CREDP) is a joint project of CARICOM and the German International Cooperation GIZ, formerly GTZ, delivering technical expertise to renewable energy projects. CREDP seeks to remove barriers for the use of Renewable Energy and application of Energy Efficiency measures in the Caribbean Region. In Guyana, CREDP is currently providing technical support to a small hydro-power project in Kato, as well as a business in Georgetown in utilising PV.
The SIDS DOCK Support Programme is a joint initiative of UNDP and the World Bank, developed in close consultation with the Alliance of Small Island States. This initiative aims to support Small Island Developing States (SIDS) to transition to low-emission economies through development and deployment of renewable energy resources and promotion of greater energy efficiency. An important component is the one-stop-shop function, facilitating SIDS's access to global financial flows, especially from the carbon market enabling them to fund transformational energy policies.
The programme was from July 2011 to December 2012. Funding of US$14.5 million was mobilized from the Government of Denmark.
The Solar Electric Light Fund (SELF) is a non-profit organization whose mission is to design, fund and implement solar energy solutions to benefit those in poor rural communities without access to an electrical grid. This allows students to study at night and brings computers and Internet into schools. It makes it possible to bring in water for irrigation without having to hand-carry it long distances, allowing women to spend their time on money-earning enterprises. Access to electricity and water improves health care. SELF has completed several projects in more than 20 countries including a solar powered drip irrigation in Benin, a health care centre in Haiti, telemedicine in the Amazon rainforest, online learning platform in South Africa, and a microenterprise development in Nigeria.
Off-the-grid or off-grid is a characteristic of buildings and a lifestyle designed in an independent manner without reliance on one or more public utilities. The term "off-the-grid" traditionally refers to not being connected to the electrical grid, but can also include other utilities like water, gas, and sewer systems, and can scale from residential homes to small communities. Off-the-grid living allows for buildings and people to be self-sufficient, which is advantageous in isolated locations where normal utilities cannot reach and is attractive to those who want to reduce environmental impact and cost of living. Generally, an off-grid building must be able to supply energy and potable water for itself, as well as manage food, waste and wastewater.
Microgeneration is the small-scale production of heat or electric power from a "low carbon source," as an alternative or supplement to traditional centralized grid-connected power.
Hybrid power are combinations between different technologies to produce power.
Solar power is a fast-growing industry in Australia. As of September 2023, Australia's over 3.60 million solar PV installations had a combined capacity of 32.9 GW photovoltaic (PV) solar power, of which at least 3,823 MW were installed in the preceding 12 months. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW were either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 12.4% of Australia's total electrical energy production in 2021.
India's solar power installed capacity was 73.32 GWAC as of 31 December 2023.
For solar power, South Asia has the ideal combination of both high solar insolation and a high density of potential customers.
The developing nations of Africa are popular locations for the application of renewable energy technology. Currently, many nations already have small-scale solar, wind, and geothermal devices in operation providing energy to urban and rural populations. These types of energy production are especially useful in remote locations because of the excessive cost of transporting electricity from large-scale power plants. The applications of renewable energy technology has the potential to alleviate many of the problems that face Africans every day, especially if done in a sustainable manner that prioritizes human rights.
Financial incentives for photovoltaics are incentives offered to electricity consumers to install and operate solar-electric generating systems, also known as photovoltaics (PV).
Solar power has a small role in electricity production in the United Kingdom.
Renewable energy in the United Kingdom contributes to production for electricity, heat, and transport.
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine.
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery.
Solar power has been growing rapidly in the U.S. state of California because of high insolation, community support, declining solar costs, and a renewable portfolio standard which requires that 60% of California's electricity come from renewable resources by 2030, with 100% by 2045. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.
Renewable energy in Tuvalu is a growing sector of the country's energy supply. Tuvalu has committed to sourcing 100% of its electricity from renewable energy. This is considered possible because of the small size of the population of Tuvalu and its abundant solar energy resources due to its tropical location. It is somewhat complicated because Tuvalu consists of nine inhabited islands. The Tuvalu National Energy Policy (TNEP) was formulated in 2009, and the Energy Strategic Action Plan defines and directs current and future energy developments so that Tuvalu can achieve the ambitious target of 100% renewable energy for power generation by 2020. The program is expected to cost 20 million US dollars and is supported by the e8, a group of 10 electric companies from G8 countries. The Government of Tuvalu worked with the e8 group to develop the Tuvalu Solar Power Project, which is a 40 kW grid-connected solar system that is intended to provide about 5% of Funafuti’s peak demand, and 3% of the Tuvalu Electricity Corporation's annual household consumption.
The energy sector in Hawaii has rapidly adopted solar power due to the high costs of electricity, and good solar resources, and has one of the highest per capita rates of solar power in the United States. Hawaii's imported energy costs, mostly for imported petroleum and coal, are three to four times higher than the mainland, so Hawaii has motivation to become one of the highest users of solar energy. Hawaii was the first state in the United States to reach grid parity for photovoltaics. Its tropical location provides abundant ambient energy.
Solar power is an important contributor to electricity generation in Italy, accounting for 8% of the total in 2017. As of 2022, the country has a total installed capacity of 22.56 GW. In 2019, Italy set a national goal of reaching 50 GW by 2030.
Solar power in Mexico has the potential to produce vast amounts of energy. 70% of the country has an insolation of greater than 4.5 kWh/m2/day. Using 15% efficient photovoltaics, a square 25 km (16 mi) on each side in the state of Chihuahua or the Sonoran Desert could supply all of Mexico's electricity.
The following outline is provided as an overview of and topical guide to solar energy:
The Australian Renewable Energy Agency (ARENA) is an independent agency of the Australian federal government, established in 2012 to manage Australia's renewable energy programs, with the objective of increasing supply and competitiveness of Australian renewable energy sources.
