There are several types of renewable energy systems that can be used in duplex villas:
1. Solar energy systems: These systems harness energy from the sun using photovoltaic (PV) panels. The energy can be used for lighting, heating, cooling, and other household appliances.
2. Wind energy systems: These systems generate electricity from wind turbines, which can be installed on the rooftop or in the backyard of the villa.
3. Geothermal energy systems: These systems use the heat from the earth to provide heating and cooling, through the use of geothermal heat pumps.
4. Hydroelectric energy systems: These systems generate electricity from the flow of water through a turbine, which can be installed near a stream or river.
5. Biomass energy systems: These systems use organic matter, such as wood or agricultural waste, to generate heat or electricity.
6. Micro-hydro energy systems: These are small-scale hydroelectric systems that can generate electricity from water flowing through a small turbine, typically used in off-grid locations.
