Africa is set to become increasingly influential in shaping global energy trends over the next two decades as it undergoes the largest process of urbanisation the world has ever seen, a new report from the International Energy Agency (IEA) said on Friday.
‘Africa Energy Outlook 2019’, a special in-depth study, finds that current policy and investment plans in African countries are not enough to meet the energy needs of the continent’s young and rapidly growing population.
Today, 600 million people in Africa do not have access to electricity and 900 million lack access to clean cooking facilities.
The number of people living in Africa’s cities is expected to expand by 600 million over the next two decades, much higher than the increase experienced by China’s cities during the country’s 20-year economic and energy boom.
Africa’s overall population is set to exceed 2 billion before 2040, accounting for half of the global increase over that period.
These profound changes will drive the continent’s economic growth, infrastructure development and, in turn, energy demand, which is projected to rise 60 per cent to around 1,320 million tonnes of oil equivalent in 2040, based on current policies and plans.
The new report is the IEA’s most comprehensive and detailed work to date on energy across the African continent, with a particular emphasis on sub-Saharan Africa.
It includes detailed energy profiles of 11 countries that represent three-quarters of the region’s gross domestic product and energy demand, including Nigeria, South Africa, Ethiopia, Kenya and Ghana.
The report makes clear that Africa’s energy future is not predetermined.
Current plans would leave 530 million people on the continent still without access to electricity in 2030, falling well short of universal access, a major development goal.
But with the right policies, it could reach that target while also becoming the first continent to develop its economy mainly through the use of modern energy sources.
Drawing on rich natural resources and advances in technology, the continent could by 2040 meet the energy demands of an economy four times larger than today’s with only 50 per cent more energy.
“Africa has a unique opportunity to pursue a much less carbon-intensive development path than many other parts of the world,” IEA’s Executive Director Fatih Birol said.
“To achieve this, it has to take advantage of the huge potential that solar, wind, hydropower, natural gas and energy efficiency offer. For example, Africa has the richest solar resources on the planet, but has so far installed only 5 gigawatts of solar photovoltaics (PV), which is less than one per cent of global capacity.”
If policy makers put a strong emphasis on clean energy technologies, solar Photovoltaic (PV) could become the continent’s largest electricity source in terms of installed capacity by 2040.
Natural gas, meanwhile, is likely to correspond well with Africa’s industrial growth drive and need for flexible electricity supply.
Today, the share of gas in sub-Saharan Africa’s energy mix is the lowest of any region in the world.
But that could be about to change, especially considering the supplies Africa has at its disposal — it is home to more than 40 per cent of global gas discoveries so far this decade, notably in Egypt, Mozambique and Tanzania.
Africa’s natural resources aren’t limited to sunshine and other energy sources. It also possesses major reserves of minerals such as cobalt and platinum that are needed in fast-growing clean energy industries.
“Africa holds the key for global energy transitions, as it is the continent with the most important ingredients for producing critical technologies,” Birol said.
African countries are on the front line when it comes to climate change, meaning the continent’s energy infrastructure planning must be climate resilient.
“Even though Africa has produced only around two per cent of the world’s energy related CO2 emissions to date, its ecosystems already suffer disproportionately from the effects of a changing climate,” Birol added. (IANS)
Indian origin girls -- New Jersey-based Natasha Peri (11) and Dubai-based Priyamvada Deshmukh (12) -- have been named in the worlds "brightest" students list based on results of above-grade-level testing of 19,000 students across 84 countries, according to Johns Hopkins Center for Talented Youth (CTY), a part of Johns Hopkins University in Baltimore, Maryland.
"Peri, a student at Thelma L. Sandmeier Elementary School, was honored for exceptional performance on the SAT, ACT, or similar assessment is taken as part of the CTY Talent Search," said a statement from the CTY.
Deshmukh, a student of GEMS Modern Academy, Dubai, has been honored for her exceptional performance on the SCAT assessment taken as part of the CTY Talent Search, a university statement said.
She was one of nearly 19,000 students from 84 countries who joined CTY in the 2019-21 Talent Search years. CTY uses above-grade-level testing to identify advanced students from around the world and provide a clear picture of their true academic abilities.
Peri took the Johns Hopkins Talent Search test in Spring 2021 when she was in Grade 5. Her results in the verbal and quantitative sections leveled with the 90th percentile of advanced Grade 8 performance.
"This motivates me to do more," she said, adding that doodling and reading J.R.R Tolkien's novels may have worked for her.
Deshmukh took the Johns Hopkins Talent Search test in Spring 2020 when she was still in Grade 6. Her results in the verbal sections leveled with the advanced Grade 10 performance. She made the cut for Johns Hopkins CTY 'High Honors Awards'.
Due to the Covid19, induced delay in Global logistics support, she finally received her much-awaited "High Honors" pin this week, which she lovingly kept in front of her Grandparents photograph as a tribute to her roots.
The delay in officially getting the certificates did not stop her from attending the summer program at John Hopkins University's CTY in English literature where she studied the confluence of Art and Science in literary writing and completed the course scoring 'A' Grade.
She followed up with top-scoring the second level of Asset Talent Examination which also qualified her for the summer program at Northwestern University this year, where she is learning about world-building in fiction writing this year.
Her elder brother was among the first UAE students to have cleared the Duke University TIP (Talent Identification Programme) when he was in Class 8.
Her parents joke that it's nothing but routine sibling rivalry that she wanted to achieve the same, just a year ahead of her brother. Even though she loves Physics and Computer Science as subjects, unlike her elder brother (who is Chancellor's Scholarship holder student of Astro Physics at the University of Massachusetts), Deshmukh wants to pursue humanities and literature when she goes to college five years down the lane.
As part of Johns Hopkins policy, granular information is not broken down by age or race.
Likewise, it is left to the guardian to disclose the prodigy's name. Within the US, awardees come from all 50 US states.
"We are thrilled to celebrate these students," said Virginia Roach, CTY's executive director.
"In a year that was anything but ordinary, their love of learning shined through, and we are excited to help cultivate their growth as scholars and citizens throughout high school, college, and beyond," Roach added.
The quantitative section of the Johns Hopkins CTY test measures the ability to see relationships between quantities expressed in mathematical terms, the verbal section measures understanding of the meaning of words and the relationships between them.
Basil scientifically called Ocimum basilicum, and also known as great basil, is a culinary herb from the Lamiaceae (mints) family. A common aromatic herb, it is usually used to add flavor to a variety of recipes, but what may astonish one is that there are various health benefits of basil that make it well-known for its immunity-enhancing properties.
Basil seeds or basil essential oil are proven to help prevent a wide range of health conditions, which makes it one of the most essential medical herbs known today. Basil has vitamin A, C, E, K, and Omega 3 components including cooling components too. It also contains minerals like Copper, Calcium, Manganese, Phosphorus, Zinc, and Potassium. An ancient Ayurvedic herb, basil has various proven benefits including being anti-inflammatory, ant-oxidant, immune-booster, pain-reducer, and blood vessel-protector.

This herb also contains cooling components thus making it really helpful for summers. It detoxifies the body and maintains one's body temperature pace. Adding to the benefits Basil contains antioxidant-rich volatile essential oils, which are considered hydrophobic, meaning they don't dissolve in water and are light and small enough to travel through the air and the pores within our skin. Basil's volatile essential oil is something that gives the herb its distinct smell and taste, but basil contains some great healing properties.
In the long history of Ayurveda, basil seeds were also called tukmaria seeds. These seeds may support one's gut health, may complete one's fiber quota, reduce blood sugar, help in weight loss, and also reduce cholesterol.
The herb has rounded leaves.Pixabay
There are more than 60 varieties of basil, with sweet basil being one of the most widely used. The herb has rounded leaves that are often pointed. It is a bright green plant, although some varieties have hints of purple or red in their leaves, basil makes a colorful and flavorful addition to many different dishes.
It has been observed that many of the cooks use basil to thicken their dessert instead of using any artificial/ unhealthy powder to do so. Sometimes people are not able to differentiate between Chia seeds and basil seeds, to make it clear basil seeds are different in nature they are larger and a bit duller in their color. These herbs are used in various recipes as a cooling component in desserts, drinks, and fruit juices for refreshment, also beating the summer heat.
For better digestion, weight loss, and immune system, I suggest this simple recipe which can be easily made at home:
*Take 2 tsp of Basil seeds (sabja) + Add in 1/2 liter of water +10 mint leaves crushed
*1/2 tsp cinnamon powder + A little bit of sendha salt (pink Himalayan salt)
*Or to make a sweeter version one can add organic honey.
*Mix it well and drink it.
This recipe will help to flush out toxins from our body making it feel light and healthy. (IANS/SP)
The US researchers have discovered a class of immune cells that plays a role in miscarriage, which affects about a quarter of pregnancies.
Researchers at the University of California-San Francisco found that the recently discovered subset of cells known as extrathymic Aire-expressing cells in the immune system may prevent the mother's immune system from attacking the placenta and fetus.
The researchers showed that pregnant mice who did not have this subset of cells were twice as likely to miscarry, and in many of these pregnancies fetal growth was severely restricted.

"When you're pregnant, the immune system is seeing the placenta for the first time in decades -- not since the mother made a placenta when she herself was a fetus," said Eva Gillis-Buck, from UCSF.
"Our research suggests that this subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the fetus, the placenta and other tissues involved in pregnancy," she added. The findings are published in the journal Science Immunology.
The immune system has to be educated not to attack one's own tissues and organs to prevent autoimmune disease. But pregnancy presents a unique challenge since the fetus expresses proteins found in the placenta as well as proteins whose genetics are distinct from the mother.

"It was a conceptual leap to link Aire-expressing cells, which are critical for preventing autoimmune disease, to pregnancy," said Tippi Mackenzie, Professor of Surgery at UCSF's Center for Maternal Foetal Precision Medicine.
In the thymus, Aire-expressing cells begin interacting with other immune cells very early in life to teach them what not to attack. The thymus begins to shrink and is nearly gone by adulthood, by which time most immune cells have been educated. But as the thymus shrinks, the population of eTACs in lymph nodes and the spleen expands, the researchers explained.
The study suggests a healthy pregnancy may depend on having these cells around, they added. (IANS/KB)
