As of recent estimates, approximately 2.4 billion people worldwide still rely on wood as their primary energy source, primarily for cooking and heating in developing regions. This reliance is particularly prevalent in parts of Africa, Asia, and Latin America, where access to modern energy sources is limited. The use of wood as an energy source poses challenges related to health, environmental sustainability, and deforestation. Efforts are ongoing to provide cleaner and more sustainable energy alternatives to these communities.
