Goal 7: Affordable and Clean Energy
Needs:
It needs to be made of locally available materials
Since transportation of materials is emits greenhouse gases, the product needs to be made of locally available materials, to eliminate this factor of pollution.
It needs to have a safety storage for extra energy
Energy blackouts are frequent in these countries, and therefore, the product needs t be able to store energy that can be used in those scenarios.
It needs to be cost efficient
Since many people in these countries are struggling financially, the initial setup/production cost needs to be lower than the value of the energy is will potentially produce.
It needs to be size efficient
Many of these countries are overpopulated, and therefore the product cannot be too big compared to the energy it provides.
The product needs to be cheaper than existing fossil fuels,
This is important, since many people are struggling financially in these countries, the energy needs to be cheaper
The product needs to be producing 100% renewable energy
This is important so that the product does not contribute at all to global warming
TA:
Where:
Sub- Saharan Africa
Who:
Producer/funder:
Government Agencies
NGO's
Private Companies
User:
Why:
The majority of the energy produced and used in this are of the world are comes from non-renwable sources like oil, and other fossil fuels.
In these countries, the average income is very low, so there are many people who cannot afford electricity all the time, and some even not at all.
How:
The goal of the product is to create a product that creates low-cost, yet sustainable energy that is accessible for as many people as possible.

For the investment to produce and set up this product (power plant) to be "worth it" for the users, the cost of the product needs to be lower than the energy it will produce. The price of the sold energy needs to surpass the cost for manufacturing it within 5 years.
Average Electricity consumption in Sub-Saharan Africa is 483 KwH per capita per year.
If each new power plant can give energy to 5000 -10000 people yearly, that would become 2.5-5 million KwH yearly.
If the electricity from the power plant costs USD 0.1/KwH, the power plant would make 250 000 to 500 000 USD yearly.
So then, the production of the power plant would cost less than 1.25 million USD.
