Renewable energy as a factor of sustainable development and regulation of ecological problems in Africa

Abstract

The analysis of the main directions of renewable energy in Africa, as a factor in sustainable development and reduction of greenhouse gas emissions is performed. The ecological problems of the modern and prospective development of the energy complex of African countries are considered. For African countries the issue of ensuring reliable and environmentally friendly access to electricity for the population is extremely acute. It is shown, that the electricity demand for industry in Sub-Saharan Africa the most problematic region is growing on a very large scale. The construction of new large coal-fired thermal power plants in the required volumes will lead to serious environmental and climatic consequences. The study of regional data allowed us to conclude that PV solar systems are of priority importance for increasing people’s access to electricity in rural SubSaharan Africa. Based on numerous materials from international energy structures the estimates and calculations of volumes of reduction of greenhouse gas emissions due to the use of renewable energy sources as an alternative to carbon fuel are carried out. The study has shown that of particularly great importance for reducing CO2 emissions in Kenya is the development of geothermal energy.

Biodigester models used worldwide in the context of intelligent cities

“…Entretanto, o modelo de cúpula fixa enfrenta gargalos relevantes quando instalados em áreas muito vulneráveis como em Camarões, onde o projeto da planta de biogás falhou pela falta de fornecimento de água para adicionar ao substrato, tornando os sólidos totais muito altos para o funcionamento eficiente do digestor (MUNGWE et al, 2016). Há um campo promissor para a inserção de biodigestores em ações de produtividade de energia limpa atrelada à problemática do lixo no continente africano, que ainda esbarram, contudo, em barreiras associadas com a falta de normativas regulatórias (NEFEDOVA et al, 2020;SEMELANE;TAZVINGA;NZAKI, 2018).…”
