ERG Research Shows Reliability of Independent Solar Power in Sub-Saharan Africa

Nature Energy recently published research by ERG PhD Student Jonathan Lee and Professor Duncan Callaway quantifying the cost of reliability for decentralized solar and battery systems in Sub-Saharan Africa. Their research finds that falling costs of solar photovoltaics and lithium-ion batteries is enabling decentralized solar plus storage systems to be increasingly cost-competitive with traditional electricity grids in Sub-Saharan Africa at reliability that matches or exceeds traditional grids. They also find a scaling pattern that above 90% reliability, decentralized systems can be designed to have higher reliabilities by increasing the levelized cost of energy by $0.11 / kWh per additional “9” of reliability (i.e. going to 99%, 99.9%, and higher) on average.

Geographic Variation in Levelized Cost of Electricity for Representative Decentralized Solar System

Lee and Callaway have made their model available online with an interactive interface as a research and decision-support tool at https://emac.berkeley.edu/reliability.

ERG Student Zeke Hausfather Maps Global Warming

                  “Climate change is often communicated by looking at the global average temperature. But a global average might not mean much to the average person. How the climate is likely to change specifically where people live is, in most cases, a much more important consideration.” – Zeke […]

Carbon Footprint Map by ERG Alum Chris Jones is Putting Pressure on Bay Area Cities

Earlier this month, the Global Climate Action Summit convened in San Francisco to discuss ambitious climate action targets for global emissions by 2020, setting the stage to reach net zero emissions by midcentury.​​ Chris Jones, ERG alum and lead developer at UC Berkeley’s CoolClimate Network, spoke about his team’s interactive map of the Bay Area, color-coded […]

ERG Alumni Deshmukh, Mileva, and Wu Explore Renewable Alternatives to Mega Hydropower

ERG alumni Ranjit Deshmukh, Ana Mileva, and Grace Wu recently published their research on alternatives to the hydroelectric power Inga III Dam in the Democratic Republic of Congo (DRC). The team explores the feasibility and cost-effectiveness of possible renewable energy options, which offer lower economic, social, and environmental risks. “Given these [environmental and social] shortcomings, developing […]
