Planning a more reliable electricity grid
A. Dr Amina Rahman: She argues that household batteries should be judged by how many years they remain useful, not only by how much energy they store on day one.
B. Professor Daniel Cho: He supports shifting some electricity use to off-peak hours, saying that demand planning can reduce pressure without building as many new power stations.
C. Engineer Sofia Mendes: She recommends small local storage systems for remote villages where extending the main grid is costly, while noting that repairs must be available nearby.
D. Dr Marcus Bell: He says any new pricing plan must protect low-income households, because a technically efficient system can still be unfair if people cannot afford peak rates.
