The use or existence of renewable energy is not directly related to carbon emissions. Ghana had a 3.54% carbon footprint in 2016, while Africa's global compounded carbon footprint is expected to be 3.8% by 2021. This means that Africa's contribution to the total of 76% of CO2 emissions is extremely small.

Renewable energy sources are more of a convenience factor than a global concern. In remote villages, using a solar-paneled lamp at night is easier and safer than using a kerosene lamp. How much more expensive is kerosene today compared to 20 years ago?

Renewable energy will not be able to replace conventional energy. Take note that the amount of fossil fuels used to manufacture an electric car's battery is greater than the amount used to drive 60 (average fuel consumption) cars over a 100km road.

For a family, having a well dug within their property is safer and easier than having the kids run to the streams at night out of a rampant fear of watercraft. Renewable energy sources play an important role.

How many years do we need to wait for geothermal sources?

Is electricity, by the way, not derived from a renewable source? Dams are used to generate electricity from naturally flowing streams that are fed by an inland flow of water.

The more living things die, the more biomass there is. Renewables will always be a question, as old as recycling and as new as 7th generation electric vehicles.

I am ready to learn more from you.

Off shore wind energy in your context should refer to the use of winds blown from the land towards the water bodies. It is important to evaluate the amount of offshore wind energy we have available.

Every project is feasible depending on the necessity, emergency and cost of the projects. Offshore winds utilisation is not a profitable one for Africa.

Of course, offshore wind energy is set to grow. At the moment only about 1.7 Tera Watts are mobilised on an average using windmills. Wherever need be, the resources could be better utilized. It is not Africa's priority and shouldn't be.

What Africans could do is research and optimistic analysis of such a project, bringing it to lower scales could be better. For example, having a team of mechanical and electrical engineering students designing local windmills in localities to assist with increasing access to electricity (this is the end of point of wind energy utilisation).

The goal of blockchain is to mobilise digital currencies. The link with energy supply is a far-fetched but not very much insignificant link. The structure of blockchain should be similar to that of internet communication (fluidity of data flux). Blockchain technology will be influenced more by economic transactions between energy suppliers and consumers in the energy sector. The blockchain technology issue is narrowed down to purchasing ability and mobility. Whether the energy is renewable or not, the question becomes relevant if "cryptos" are used to pay. Many countries already use the P-2-P transaction, which allows traditional currencies, bank cards, and crypto vendor platforms to be purchased (such as Binance without any publicity). When considering this question in terms of mining these coins, the CPU units, According to the Digiconomist's Bitcoin Energy Consumption Index, one bitcoin transaction consumes 1,449 kWh, or roughly 50 days of power for the average US household. Many African businesses consume more energy than this over the course of 50 days. As a result, it has no bearing on Africa's energy sustainability. Africa's most pressing issue is how to manage the energy it generates (how the laws work and how much people can buy). I hope I've quenched your thirst.

By the way, how many countries are to adopt a currency which doesn't satisfy the basis laws of currency credibility?

How many fishers will be ready to tell you, fishing at large scale is very profitable? How many even in your environment will consistently encourage and mentor you to gain more.

The role of an engineer, beyond his analytical sense and political ambitions is that of developing substantial growth even low scale.

As a computer engineer (that's how you ought to be addressed even by yourself: the consciousness of who you are) no one hinders you from developing programs and tools to solve issues in your community. Renewable energies utilisation could be part of it.

Have you ever thought of how in coaction with other engineers around you, you could mobilise waste resources in Buea to make it active?

What of developing plants which will assist the women along the Muea market to easily wash their fish for example?

What of extension to use streams, to generate electricity for Student hostels or automation of water plants in student hostels.

Your question shows you have interest in solving Education and Health issues? What plans have you taken towards that? If you do consistently, the same funding agencies will come to you, then we could assess your loyalty to solve Africa's problems with your skills.

The earlier we stop the blame game, the better.

You might also want to host a session which people who share interest in your field. This particular session comes from a public demand to elucidate with persons having interest in renewable energies.
