Sub-Saharan Africa, Subsahara, or Non-Mediterranean Africa is the area and regions of the continent of Africa that lie south of the Sahara. These include Central Africa, East Africa, Southern Africa, and West Africa. Geopolitically, in addition to the African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region. The African Union (AU) uses a different regional breakdown, recognizing all 55 member states on the continent—grouping them into five distinct and standard regions.

Rural electrification is the process of bringing electrical power to rural and remote areas. Rural communities are suffering from colossal market failures as the national grids fall short of their demand for electricity. As of 2019, 770 million people live without access to electricity – 10.2% of the global population. Electrification typically begins in cities and towns and gradually extends to rural areas, however, this process often runs into obstacles in developing nations. Expanding the national grid is expensive and countries consistently lack the capital to grow their current infrastructure. Additionally, amortizing capital costs to reduce the unit cost of each hook-up is harder to do in lightly populated areas. If countries are able to overcome these obstacles and reach nationwide electrification, rural communities will be able to reap considerable amounts of economic and social development.

Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. However, since 2015, investment in non-hydro renewable energy has been higher in developing countries than in developed countries, and comprised 54% of global renewable energy investment in 2019. The International Energy Agency forecasts that renewable energy will provide the majority of energy supply growth through 2030 in Africa and Central and South America, and 42% of supply growth in China.
A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of an LED lamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of a solar photovoltaic panel.
New York City Waterfalls is a public art project by artist Olafur Eliasson, in collaboration with the Public Art Fund, consisting of four man-made waterfalls placed around New York City along the East River. The most famous was at the Brooklyn Bridge in lower Manhattan. At $15.5 million, it is the most expensive public arts project since Christo and Jeanne-Claude's installation of The Gates in Central Park. The waterfalls officially began flowing on June 26, 2008. They ran from 7 am to 10 pm, until October 13, 2008.
Husk Power Systems, founded in 2008, is a company based in Fort Collins, Colorado, US, that provides clean energy services to off-grid or weak grid rural communities in East Africa, West Africa and South Asia, primarily by building renewable energy mini-grids/micro-grids. Its original technology generated electricity using a biomass gasifier that created fuel from rice husks, a waste product of rice hullers that separate the husks as chaff from the rice, a staple food in both Asia and Africa. In the mid-2010s, with the rapid decline in the price of solar PV and batteries, Husk pivoted its business model to focus more on solar-plus-storage mini-grids, while continuing to use biomass in combination with solar to serve communities with larger electricity demand. In 2021, Husk Power was recognized in the REN21 Renewables Global Status Report as the first mini-grid company to achieve significant scale, by surpassing 100 solar hybrid community mini-grids, and 5,000 small business customers. In 2022, Husk signed an Energy Compact with the United Nations, in which it set a target of building 5,000 mini-grids and connecting at least 1 million customers by 2030.
Energy in Common (EIC) was a not-for-profit organization issuing microloans specifically and only for renewable energy technologies. It operated between 2009 and 2013 when it suspended its lending activity due to a lack of funds.
Energy use and development in Africa varies widely across the continent, with some African countries exporting energy to neighbors or the global market, while others lack even basic infrastructures or systems to acquire energy. The World Bank has declared 32 of the 48 nations on the continent to be in an energy crisis. Energy development has not kept pace with rising demand in developing regions, placing a large strain on the continent's existing resources over the first decade of the new century. From 2001 to 2005, GDP for over half of the countries in Sub Saharan Africa rose by over 4.5% annually, while generation capacity grew at a rate of 1.2%.
Africa is often considered and referred as the "Sun continent" or the continent where the Sun's influence is the greatest. According to the "World Sunshine Map", Africa receives many more hours of bright sunshine during the course of the year than any other continent of the Earth: and many of the sunniest countries on the planet are in Africa.

Ethiopia generates most of its electricity from renewable energy, mainly hydropower.
Nuru Energy is an international social enterprise which is working to address the global problem of energy poverty and climate change in Africa and India. This is through the distribution of affordable LED lamps that are recharged using a simple to use human powered generator that is more efficient than current solar.
Akon Lighting Africa is a project started in 2014 by music artist Akon with Samba Bathily and Thione Niang which aims to provide electricity by solar energy in Africa. Their initial technique is to install solar street lights and small energy systems.
The International Solar Alliance (ISA) is an alliance of more than 120 signatory countries, most being sunshine countries, which lie either completely or partly between the Tropic of Cancer and the Tropic of Capricorn. The primary objective of the alliance is to work for the efficient consumption of solar energy to reduce dependence on fossil fuels. This initiative was first proposed by Indian Prime Minister Narendra Modi in a speech in November 2015 at Wembley Stadium, in which he referred to sunshine countries as Suryaputra. The alliance is a treaty-based inter-governmental organization. Countries that do not fall within the Tropics can join the alliance and enjoy all benefits as other members, with the exception of voting rights.
