When Bill Gates started Microsoft he set the goal of “a computer on every desk and in every home”. Up to that point computing had been highly centralized, based around powerful mainframes and “dumb” terminals that were limited to business settings. Gates’ vision largely came to be. Personal computers...
A solar energy system is seen as a decent solution to both economic and environmental challenges. For most people, the financial case is a major factor when considering solar systems. However, the times when solar panels were expensive and only affordable by the wealthiest homeowners are gone. That has...
Renewable energy, also known as sustainable energy, originates from limitless sources like the wind, sun, biomass, geothermal and hydro. Unlike fossil fuels, clean sustainable energy is non-polluting in the production process, in which greenhouse gasses emissions and toxic waste do not form. Not only that renewable energy is environment-friendly,...
Awareness for greenhouse gas emissions and carbon footprint is a game-changer in solar energy innovation and technology towards the usage of renewable solar energy in off-the-grid, urban, and industrial areas. Solar power has become more acceptable around the globe. Generating electricity from the sun by utilizing renewable solar energy...
Background Before COVID-19, sub-Saharan Africa was home to several of the fastest-growing economies in the world. At the same time, Africa’s population was out pacing global population rates. The continent is expected to be home to over a quarter of the global population by 2050. While the pandemic is...
Education is vital for prosperous, healthy and equitable societies. However, it is almost impossible to provide communities with a formal education without access to reliable and affordable electricity services. Despite the importance of energy access as a tool to deliver education, according to the World Bank, “the vast majority...
STORY HIGHLIGHTS West Africa has made great strides in electrification, but there is still a long way to go to connect the entire population and provide everyone with reliable and affordable energy. While several countries in the subregion have significant renewable energy sources, they lack the conditions to develop...
With the lowest power consumption per capita in the world, sub-Sahara Africa is arguably the darkest section of the global village with investments, social and economic growth and jobs creation hobbled by frequent outages, load shedding and total black outs. Over 645 million Africans lack access to electricity. Yet...
African nations are accelerating their use of renewable power generation as increasing urbanization, population growth, and economic development are driving electricity demand and governments look to improve access to affordable energy. The falling cost of solar energy systems is encouraging the adoption of the technology across sub-Saharan Africa, as...
