Water system
The water system of our house works using rainwater that goes through some filters to be drinkable.
Wood and Windows
Windows and wood are made from recycled plastic,
Garden
It is also advisable to use a garden to plant vegetables and fruits, for example in my grandmother's house it is not a garden but she has some pots where she grows green peppers and tomatoes.
Etanol
The cars in our house use biodegradable fuel called ethanol, ethanol is a chemical compound obtained from the fermentation of sugars that can be used as fuel alone or mixed in varying amounts with gasoline and its use has spread mainly to replace the consumption of petroleum derivatives.
Solar panels
Solar panels are an essential feature for any eco home. They can help you economize on your electricity bills, increase your property value and help create a cleaner future for the next generations.
Energy efficient light
Not only do energy efficient bulbs use less electricity, they also last longer, which means it isn't necessary to spend money replacing them. The most energy efficient light bulbs are compact fluorescent light bulbs, or CFLS, and LED bulbs.
Insulate your home
Insulation reduces the exchange of heat through a surface such as a wall, attic, duct or roof. In a well-insulated home, less warm air escapes from the house during the winter, and less cool air escapes during the summer, reducing the amount of energy needed for heating and cooling.
