Solar energy not as green as you think

Published

on

The potential environmental effects of solar power isn’t much talked about with the benefits of it is often more publicized as green energy. Solar is a renewable energy – energy derived from a source that replenishes quicker than consumption. However, we can not say it is 0 emissions or 100% green. What are the environmental impacts of solar panels?

Land usage

Solar panels depending upon their location can use up a sizable amount of land. The total area of land needed can vary depending on the techniques used to build the farm. The estimated land usage for PV solar settings ranges from 3.5 to 10 acres per megawatt and estimations for CSP facilities range between 4 and 16.5 acres per megawatt.

Unlike wind turbines, there is less opportunity for solar projects to share the land. However, the land utility problem can be minimized by choosing the right location such as abandoned mining sites and rooftops of existing buildings. Deforestation can also be another threat due to the land clearance needed for solar installation.

Water Usage

Water us used in the manufacturing process of solar panels. The water is used to manufacture solar PV components. CSP panels 2300 to 2500 liters of water per megawatt-hour.

Hazardous Materials

The PV cell manufacturing process requires a number of hazardous materials most of which are used to clean and purify the semiconductor surface. Silicon dust can cause a loss of health problems when inhaled. PV cells contain a number of more toxic materials. If not handled and disposed of properly, these chemicals can cause serious environmental problems.

Carbon Footprint

The manufacturing of PV cells requires some minerals like copper, nickel, and cadmium and the lining of these minerals emits carbon and requires energy that might be coming from fossils. mining also causes deforestation and soil erosion.

Hard to dispose

Currently, there are no large companies doing mass recycling of solar panels leaving the junk of unusable panels with not so good ways to dispose of them. Most panels of high quality have a lifespan of 25-35 years but with the introduction of cheaper ranges from China, their lifespan can be a minimal as 5 years.

Comparison with nuclear power

Solar Energy has a death rate of 0.44 deaths per TWh while nuclear has only 0.04 deaths per TWh. In the United States, nuclear energy costs $0.02 per KWh while solar costs $0.12 per kWh. It will take about 177 Square millimeters of land with solar panels to produce the same amount of one nuclear power station.

Conclusion

While solar energy is very promising as a renewable source of energy, more has to be done to ensure that the problems it posses can be minimized.

Visa Free Into Nigeria in 2020 – Nigerian President

The president of Nigeria Muhammadu Buhari has announced a visa-free entrance into Nigeria for all people holding passports of African countries.

Published

The president of Nigeria Major General Muhammadu Buhari has announced a visa-free entrance into Nigeria for all people holding passports of African countries. President Buhari announced this at the Aswan Forum in Egypt. This will come into effect beginning in January 2020.

Nigeria is one of the countries in strong support of the free movement of Africans in the African continent as this has a number of advantages for African economies to share skills, culture and resources effectively. One of the major barriers we have been limited by as Africans is the inability to distribute our goods and services in cross-border trade and the requirement of visas and approvals limits the rate at which trade can be carried out effectively.

Some have expressed concerns over the president’s decision outlining the fact that other African countries still need Nigerians to apply for visas. Other concerns were that of the potential influx of migrants from neighboring nations who might add on top of the current problems Nigerians are facing like high unemployment rates.

Critics on Twitter have gone to say that, instead of pursuing such policies, there are other pressing matters the president must be currently addressing.

Fairly speaking, the idea of a visa-free movement across Africa could benefit Africans more than the harms it might bring about. In order for Africans to achieve the global economic status of the upcoming fourth industrial revolution, free movement and open trade are crucial. The question is, who is to start by opening up to welcome others?

We expect to see other countries choosing a similar path. “Someone has to lower his guard and start it. There’s what they call reciprocity in international diplomacy. Wait and see how other African countries will gradually follow suit.” Said a commenter on Twitter.

Some Nigerian nationals have expressed doubt against the idea of pioneering such a policy since they believe it is very unlikely that other countries like South Africa, Kenya, and Ethiopia would implement such a policy.

What do you think about Nigeria opening up free movement?

Ever heard of the term “black is beautiful”? Well, whether you might have believed it or not, the world has confirmed it. Although it is not the first time for black women to win the pageant crowns, this moment in 2019 is unique because four of the major pageant titles are being held by black women. The crowning of Miss Universe Zozibini Ntunzi on the 8th of December in Atlanta, Georgia was the biggest proud-maker amongst people of color. Miss Universe, Miss USA, Miss Teen USA and Miss America are all women of color.

Having four beautiful black ladies holding these prestigious crowns is by no means a coincidence. It reflects the current trend and state of mind worldwide. Looking back at our history, we see a very swift change in social perception as we see black women being recognized for their beauty and this goes a long way instilling self-confidence among women of color. The world has changed remarkably and it seems like it is time for people of color people to take up their place in society.

“The most important thing we should be teaching young girls today is leadership. It’s something that has been lacking in young women and girls for a very long time, not because we don’t want to [lead], but because of what society has labelled women to be. I think we are the most powerful beings in the world and that we should be given every opportunity, and that is what we should be teaching these young girls- to take up space. Nothing is as important as taking up space and cementing yourself.”

We see maturity, tolerance, unbiased love and erasure of racial boundaries when things like these happen. These ladies do not only give a sense of pride to women but to millions of men who care for their black queens.

Miss Universe

Miss Universe is the biggest and the most prestigious pageant competition on the planet. Zozibini Ntunzi of South Africa won the 2019 crown as she has taken the world by storm with her elegance, beauty and captivating aura as well as her eloquent way of answering questions. On the night of the announcement, cheers were already coming from the audience from all over the world whom she had won their hearts.

One thing very special about Zozibini is her hairstyle. She did not wear a weave nor excessive make-up. She stood tall with her beautiful smile representing the natural features of a black woman and the universe has recognized her natural beauty. It does not matter if you are a fan of natural hair or not if you are a woman of color be proud of who you are because you are beautiful.

Miss USA, Miss America and Miss Teen USA

Earlier in May 2019, another beautiful woman Amerian television presenter Cheslie Kryst of North Carolina United States was crowned as Miss USA at the event held in Nevada.

Miss Teen USA’s crown is prestigiously held by Hailey Colborn, another pretty woman of color From Kansas. This a symbol of black excellence. As we move on, we see the world slowly but surely ignoring racial lines and there is a very good sign of hope that one day we will all talk in terms of people as people without thinking about race at all. This is just the beginning.
