As global energy markets remain volatile and oil prices stay high due to instability and conflict in the Middle East, more countries are investing in renewable energy to shield their economies from fossil fuel shocks, reduce import bills, and meet climate targets, according to a press release published by United Nations (UN) on April 26, 2026. The report, the second in a series on renewables and energy security, examines four countries striving to increase the share of greener energy sources. Across Germany, India, Bolivia, and Nigeria, a clear trend is emerging: renewables are strengthening energy security while reducing dependence on volatile fossil fuel markets.
Unlike oil and gas, renewables offer stable, domestically produced power that can cut greenhouse gas emissions and support long-term growth. UN Secretary-General António Guterres stated in March: “The fastest path to energy security, economic security, and national security is clear: speed up a just transition away from fossil fuels and toward renewable energy.” Each of the four countries examined faces distinct structural challenges but shares a common push toward cleaner energy systems. Fossil fuels remain dominant across all four nations even as renewable capacity expands.
Germany’s renewables now provide 55 per cent of electricity consumption, with wind as the leading source, though grid stability and fossil fuel backup during the transition remain key challenges. India’s renewables account for around 30% of installed capacity, with solar expanding rapidly, while coal remains dominant and affordability concerns persist. Bolivia generates around 30–35% of its electricity from renewables, with hydropower leading, but heavy structural dependence on natural gas and limited financing slow the transition. Nigeria, Africa’s largest economy, generates around 20–25 per cent of electricity from renewables and aims to reach 50 per cent by 2030, despite frequent power shortages and reliance on diesel generators.
Progress is visible across all four countries. Germany is expanding offshore wind and solar while modernizing its grid, with storage investment described as “crucial” to the transition. India is scaling large solar parks, rooftop systems, and green hydrogen initiatives, with solar-powered livelihood programmes improving energy access in rural communities. Bolivia is advancing solar expansion in rural and high-altitude regions alongside wind farm development and a national renewable growth roadmap. Nigeria is growing off-grid solar and mini-grid systems, backed by national electrification programmes and increasing investment in home solar systems.
Challenges remain across all four economies, spanning financing gaps, infrastructure deficits, and the need to balance reliability with rapid renewable expansion. Nigeria must still build a more reliable grid and reduce industry’s reliance on gas-fired power plants to meet its 2030 target. Bolivia’s dependence on gas revenues and existing fossil fuel infrastructure continues to complicate a rapid shift. From industrialized Germany to developing nations such as Nigeria, the evidence points to renewables delivering tangible benefits to people and economies while reducing exposure to volatile global fuel markets.
