In Liberia, the availability of grid-connected electricity is limited, which has one of the world's lowest electricity consumption rates with <50 kWh per capita per year. As shown in Fig. 8, i. [pdf]
The update highlights key advancements in Liberia's energy sector, including notable progress in power generation and the expansion of energy access. However, despite these gains, the country faces significant power shortages, calling for substantial investments to achieve reliable, affordable, and sustainable energy access for all Liberians.
The report offers a comprehensive analysis of recent economic developments in Liberia, underscoring the crucial role of reliable energy in fostering sustainable growth. The update highlights key advancements in Liberia's energy sector, including notable progress in power generation and the expansion of energy access.
The country will need to invest heavily in energy infrastructure to achieve universal access to electricity by 2030 . The primary energy sources in Liberia are traditional biomass fuels such as firewood and charcoal, which account for more than 80 % of the country's total energy consumption [5, 12, 13].
In addition, the government signed a Power Purchase Agreement with a solar energy company to provide the country ≥20 MW of electricity in 2020 . Despite these efforts, much work remains to be done to improve access to reliable and affordable energy in Liberia.
Additionally, adopting off-grid and mini-grid solutions presents another opportunity for energy access in Liberia . Given the challenges of extending the central grid to remote areas, off-grid and mini-grid systems offer cost-effective alternatives. Some of the energy sources utilized in Liberia are summarized in Table 3. Table 3.
Petroleum products, including gasoline and diesel, contribute a significant to Liberia's energy consumption. These fuels are primarily used in transportation, power generation from small diesel and gasoline generators and industrial applications. Liberia is a net importer of petroleum products, relying on imports to meet its energy needs.

In February 2022, two days after Russia's full-scale invasion, Ukraine requested that American aerospace company SpaceX activate their Starlink satellite internet service in the country, to replace internet and communication networks degraded or destroyed during the war.

A Ukrainian serviceman stands next to a vehicle that carries a Starlink satellite internet system near the front line in Donetsk region, Ukraine, on February 27, 2023. In recent months, Russian social media channels run by crowdfunders have been increasingly open about Starlink purchases.
In February, Musk responded to Ukrainian claims the Russians were using Starlink by stating that his company did not do business with the Russian government, and that the system would not work in Russia. But Starlink was unclear if the technology might work in Russian-occupied areas of Ukraine.
The Starlink internet service has provided a significant frontline advantage to Ukraine’s smaller military since the 2022 invasion, permitting its forces to share real-time drone feeds between units, and communicate in areas where combat has disrupted cellphone service.
Russia said Starlink was not certified in their country and accordingly could not be officially supplied in Russia and was not officially used there. Similarly to SpaceX's terminals, DJI 's drones are sold in Russia without the company knowing or agreeing with the sales.
The standard package of satellite Internet by Starlink costs $110 per month. You also need to purchase equipment worth $599. Since August 24, Ukraine has received a special price: a $60 subscription fee and $385 for the equipment. The preferential price will be valid until the pricing policy is revised next time.
