Power Paradigm: Charting Africa’s Journey to Sustainable Electrification

Power Paradigm: Charting Africa’s Journey to Sustainable Electrification

 

The transformative threshold of Africa. Getting Africa on-line is not all about pulling together the disparate elements, but that this approach can be truly inspirational for the innovative technologies which shun conventional ‘hard-wired’ powers and embrace sustainable energy delivery. Despite all that, flickering of the previous shadows in some dimmed-down villages is the sign of change. Nevertheless, the narrative goes beyond the question of access and moves even further into green energy as light for illuminating our environment which is being over polluted at an unheard pace. This transformation encapsulates a dual ambition: clean and green lighting to homes, schools and factories, big and small, in this continent’s crowded cities and small villages under clear day and night skies. During the course of our discourse on details and stories surrounding Africa’s energy map, we will analyze more than just statistical aspects of electric power availability between towns and villages and the recent movement towards renewables – from darkness to sustainable light, which portrays an illuminating future.

We can also check the disparity between urban and rural areas in Africa.

Our initiative seeks to illuminate the African continent by expanding access to electricity, with the firm commitment to SDG 13.2—integrating climate change measures into national policies, strategies, and planning. We aim to electrify the future of Africa through the adoption of renewable energy solutions, ensuring that every watt powering development is also protecting our planet. By fostering the use of clean, renewable energy sources, we are not only turning on the lights but also paving the way for a sustainable and resilient energy ecosystem across African communities.

Increasing electric power consumption (kWh per capita) in Africa does not inherently lead to a rise in CO2 emissions (metric tons per capita) when we strategically incorporate renewable energy sources. By integrating solar, wind, hydro, and geothermal power into the energy mix, Africa can satisfy its growing energy needs while mitigating carbon footprint. This sustainable approach aligns with the global ambition to combat climate change, embodying the spirit of SDG 13.2. It demonstrates that economic growth and environmental stewardship can coexist, powering development that honors our collective commitment to a greener future.

We can see from this graph that in the European Union, increasing electric power consumption per capita did not lead to an increase in CO2 emissions per capita. This is due to the fact that they have increased their reliance on renewables, shown in the following graph.

In conclusion, the imperative for Africa is not just to electrify but to do so sustainably. Green energy solutions offer a pathway to empower the continent with the electricity it needs, without compromising the health of our planet. The adoption of renewable energy technologies in Africa represents a convergence of developmental aspirations with ecological responsibility. By harnessing the abundant renewable resources available, from solar to wind to hydro, Africa can leapfrog traditional, carbon-intensive energy models, setting a global example of sustainable growth. This approach not only addresses immediate energy needs but also aligns with long-term climate goals, fulfilling our collective responsibility to future generations.

Have you ever imagined a world out of coffee and chocolate?

Have you ever imagined a world out of coffee and chocolate?

Believe it or not, climate change may prevent us from enjoying many of our favorite meals in the next years. Some crops may go extinct, while others may become scarce and expensive. Who does not enjoy chocolate? The cocoa plant may be completely wiped out by 2050. Who doesn’t drink coffee in the morning? By 2100, 50% of the land will be unsuitable to grow coffee. Human activities have been the primary cause of climate change due to burning fossil fuels.

When fossil fuels are burnt, significant amount of greenhouse gases are released into the atmosphere and these gases trap heat in our atmosphere and contribute to global warming. Methane is greenhouse gas that is responsible for around 30% of the rise in global temperatures and as you can see, methane emission has increased rapidly over the years all around the globe.

Nitrous oxide is the third most major greenhouse gas, accounting for around 7% of global warming. Coffee production has declined mostly as a result of rising yearly temperatures in coffee-producing countries such as Brazil, Vietnam, Indonesia, and Colombia. This map visualizes the precent of Nitrous Oxide, the darker the color, the higher the percentage.

There is no planet B, so we shouldn’t need another reason to act and try to prevent climate change from getting worse or risk the extinction of our favorite food. The question is, what can we do? We start from ourselves. There are a lot of things that we can do as individuals to help in reducing climate change effect. We should work on generating electricity from wind, solar and other renewable sources, as opposed to fossil fuels, which emits little to no greenhouse gases or pollutants into the air. We can also help by following the rule of reduce, reuse, repair, and recycle in our everyday activities. We can also pay attention to throwaway less food, save more energy, and speak up about the issue to raise awareness.

What else can be done? Some coffee beans generally grown in hotter climates, and we should investigate more about and encourage farmers it to plant more of it in the future. We can also develop technologies to enable the adaptation of coffee production to future climatic change conditions. One of the initiatives being pursued by scientists at the University of California is to utilize new technology to help the plant survive. The team at Berkeley is working with the Mars company on gene-editing technology, to help the plant to survive in the uncertain years to come.

In 2020, emissions fell by 5.8 percent due to COVID-19 and the resulting economic crisis. Therefore, our individual efforts count, and we can make a difference!

Climate Change: The Crisis of our time

A Step Away From The Disaster

A Step Away From The Disaster

The Arab World has been witnessing an increasing number of greenhouse gas emissions (Figure-1), and we are not doing anything about it.

Figure-1

A result of This increase is the climate change which is manifested in the record-breaking temperatures witnessed in summer 2021 in several countries within the Arab World, such as, in Iraq, Kuwait, KSA and even Lebanon. High temperatures mean endangering our food security as with the high temperatures the yields of major crops are reduced, their nutritional value also, this means less supply and higher food prices.

The solution is already available, it is solar energy, as 80% of the land in the region is covered by deserts, making use of it will of course decrease the dependency on fossil fuels and that would be the first step toward tackling climate change in the region.

This solution is already being implemented by other countries, for example, the European union, and data show (Figure-2) that the total number of greenhouse gas emissions has been decreasing for them and this is associated with an increase in the proportion of their electricity output that is generated by renewable energy.

Figure-2

Finally, it is worth mentioning that for some of the European countries who are depending more on renewable energy are investing in north-African deserts such as in Algeria and Tunisia, so this is a proof that we already have significant exposure to solar radiation and enough land area, and these resources, if used correctly can make an impact in addressing the problem of climate change.

The impact of CO2 emission on Global Warming

The impact of CO2 emission on Global Warming

Antarctica has been suffering for years due to the high CO2 emission levels around the globe.

I have brought an expert that would be able to shed light on the matter based on personal experience and what he and his family have been witnessing for the past decades.

Please help me in welcoming Frosty the Penguin!

Frosty was born and raised in Antarctica by a family of scientists.

His grandfather was among the first penguins to witness the melting of glaciers and the family kept records of changes that have occurred throughout the years in Antarctica.

While growing up, his surroundings were changing rapidly due to higher temperatures.

The sled that he used to play at with his penguin friends has turned into water; friends from other species have already left, or even died at sea.

Today Carbon Dioxide levels are rising rapidly from 400mg/L in 2019, to 409mg/L in 2020 to reach 420mg/L in 2021 due to the burning of fossil fuels, industrial processes, and tropical forest destruction.

As a result, Glaciers are rapidly melting and Frosty is facing the danger of migration or even death.

CO2 emission in 1980 started increasing drastically in countries like China going from 1.5 gigatons of CO2 to a record high of 11 gigatons in 2017!

Also, countries like Indonesia have witnessed a consistent increase in emissions while we see that Germany in gypsy blue has seen a drop in their emissions despite being the number 1 producer in Europe; they must be doing something right.

Based on his recent study in 2018, countries like USA, Canada, Russia, Australia and China are among the highest emitting countries of CO2 compared to the European Continent (excluding Russia), the African continent and South America.

For Frosty, this means that the sea ice extent which represents the area of ocean where at least 15 percent of the surface is frozen has been shrinking especially in recent years due to our negligence.

However, it is still not too late to help Frosty have his home back!!

To decrease the level of CO2 emissions, many solutions are available such as:

  • Substituting car trips with bike rides or any form of public transportation.
  • Apply Emission Regulations on automobiles
  • Plant trees
  • Switch to Clean Energy

All of these solutions are easily implemented through deploying bicycles for rent off the streets, Carpooling or using Hybrid/Electric Cars as well as renewable energy.

The cheapest and considered to be one of the most efficient ways of reducing CO2 emission is planting trees to absorb and store the carbon dioxide in the atmosphere.

We can see these reforms being applied mostly in the European continent, Eastern and Western, which lead to the decrease in the level of CO2 from 1990 till 2018 as per the World Map visualization.

We urge countries to follow the steps of Europe and ameliorate their CO2 emissions by planting trees, adopting renewable energy and encouraging people to use lower emitting means of transportation
