- Solar cookers: These cookers use the power of the sun to cook food, reducing the need for firewood and saving energy.
- Biogas digesters: These systems use organic matter to produce biogas, which can be used for cooking or heating. They also produce a nutrient-rich fertilizer that can be used to improve crop yields.
- Rainwater harvesting systems: These systems collect rainwater for use in irrigation or household purposes, reducing the need for water from other sources.
- Ceramic water filters: These filters can remove bacteria and other contaminants from water, providing safe drinking water.
- Compost toilets: These toilets use a natural process to break down human waste into a nutrient-rich compost, eliminating the need for a sewer system.
- Low-cost housing technologies: These technologies use locally available materials and construction methods to build affordable, sustainable housing.
- Solar panels: Solar panels convert sunlight into electricity, which can be used to power lights, appliances, and other devices.
- Wind turbines: Wind turbines convert the energy of the wind into electricity, which can be used to power homes, businesses, and communities.
- Hydropower systems: Hydropower systems harness the energy of flowing water to generate electricity, providing a clean, renewable source of power.
- Electric vehicles: Electric vehicles use electricity to power their motors, reducing the need for gasoline and reducing air pollution.
