Some of these places only have things like cow dung, wood from local forests, or crop residue to burn. All of these are either inefficient or hurt the environment, or both. But they have been the only light sources that these people have open to them.
That may change due to a study done in Gujarat, one of Western India’s poorest states. Researchers have proposed that solar lanterns could end up being a good way to solve the problems of these countries, as well as help the environment while they are providing them a light source.
This is on the whole very true in India, where the average number of sunny days ranges from 250 to 300 per year, which makes it possible to generate solar energy equivalent to greater than the country’s total energy consumption.
Since India has such a large and growing population, solar lanterns, which would continue using the country’s abundant sunlight, may be the cleanest and most practical energy alternative available to them.
Above all, the solar lighting would both provide a cheap and easy light source to the poorest of peoples, and at the same time help save the environment from damage or loss of natural resources like trees.
