Can solar power transform Ethiopia's energy landscape?

Among these, solar energy emerges as a beacon of hope, poised to transform Ethiopia's energy landscape and drive socioeconomic development. Significantly, the country has relied heavily on hydropower, which accounts for more than 90% of its electricity generation.

Why is solar energy important in Ethiopia?

By improving energy access, solar energy can stimulate local economies, enhance educational opportunities, and improve healthcare services, thereby contributing to overall development. Moreover, the transition to solar energy aligns with Ethiopia's ambitious climate goals.

Why is Ethiopia investing 300 million USD in solar energy?

She mentioned that the country's focus is on the solar energy sector, where Ethiopia is investing 300 million USD in a project aimed at generating 300 megawatts of solar energy. It does not only support the country's renewable energy goals but also contributes to reducing carbon emissions and promoting sustainability, she said.

Why is extreme precipitation important in Ethiopia?

Extreme precipitation is an important part of extreme climate change. It is of great significance to study the distribution, trend and mechanism of extreme precipitation in Ethiopia in order to mitigate climate change. Therefore, we analyzed in detail patterns and trends of extreme precipitation through 10 widely used extreme precipitation indices.

What is the correlation between extreme precipitation indices in Ethiopia?

In Western and Southeastern Ethiopia, the correlations with three indices were negative, and the values were about −0.4 (Figure 15 d–f). For the duration indices of extreme precipitation, the correlations with R10mm were not significant in the whole of Ethiopia, and the range was −0.31 to 0.33 (Figure 15 g).

What is the trend range of r10mm in Ethiopia?

The trend range of annual R10mm for the whole of Ethiopia was −1.53 to 0.27 days/year, with the highest decline in the Northwestern Ethiopian Plateau, southern desert and savanna.

Does complementarity support integration of wind and solar resources?

Monforti et al. assessed the complementarity between wind and solar resources in Italy through Pearson correlation analysis and found that their complementarity can favourably support their integration into the energy system. Jurasz et al. simulated the operation of wind-solar HES for 86 locations in Poland.

Which cluster of wind power stations exhibit the weakest complementarity with radiation?

Analysis of the matrix reveals that the 4th, 5th, 7th, and 8th clusters of wind power stations exhibit the weakest complementarity with the radiation of photovoltaic stations. In contrast, the 5th, 7th, 8th, and 10th clusters of photovoltaic stations similarly demonstrate poor complementarity with the wind speed of wind power stations.

What is the complementary coefficient between wind power stations and photovoltaic stations?

Utilizing the clustering outcomes, we computed the complementary coefficient R between the wind speed of wind power stations and the radiation of photovoltaic stations, resulting in the following complementary coefficient matrix (Fig. 17.).

Is there a complementarity between wind and solar energy?

Studying the complementarity between wind and solar energy is crucial for optimizing the use of these renewable resources. Multi-energy compensation systems need to consider multiple metrics, and current research relies on the correlation of single metrics to study this complementarity.

Do wind and solar resources have a complementarity metric system?

To this end, we propose a novel variation-based complementarity metrics system based on the description of series' fluctuation characteristics from quantitative and contoured dimensions. From this, the complementarity between wind and solar resources in China is assessed, and the trend and persistence are tested.

How do we evaluate the complementarity of wind and solar resources?

Previous studies have primarily used the Pearson correlation coefficient (CC) and similar metrics to evaluate the complementarity of wind and solar resources. For instance, Che et al. directly calculated Pearson CC to analyze the complementarity between wind and solar power and between wind and hydropower.

Can wind energy be used to power mobile phone base stations?

Worldwide thousands of base stations provide relaying mobile phone signals. Every off-grid base station has a diesel generator up to 4 kW to provide electricity for the electronic equipment involved. The presentation will give attention to the requirements on using windenergy as an energy source for powering mobile phone base stations.

Why do off-grid telecommunication base stations need generators?

As the incessant demand for wireless communication grows, off-grid telecommunication base station sites continue to be introduced around the globe. In rural or remote areas, where power from the grid is unavailable or unreliable, these cell sites require generator sets to provide power security as prime power or backup standby power.

What are the primary sources of power for a mobile base-station?

The primary sources of power for these mobile base-station vary by region and can generally be categorized into 3 buckets: Reliable grid power: AC mains or grid power can reliably serve as the primary power supply.

What is the main source of power for a base station?

In the case of base stations situated in regions with bad-grid or off-grid power availability, the predominant source of power for the base stations is diesel generators. [4,6] Diesel generation is costly in both the procurement of fuel and travel required to maintain adequate fuel levels at the base stations.
