Final answer:
Solar powered lanterns solve multiple problems by providing access to electricity, reducing reliance on kerosene, and empowering local communities.
Step-by-step explanation:
The solar powered lanterns solve multiple problems by providing access to electricity in regions where it is lacking. This extends the day and allows people to work, study, and engage in other activities at night.
Additionally, solar power reduces the reliance on kerosene and the emission of carbon dioxide, benefiting the environment. For example, Barefoot College in India trains grandmothers as solar engineers, empowering the local community to operate and maintain the solar projects themselves.
