Los materiales más populares para el aislamiento son la fibra de vidrio y la lana de roca. Después de ser fabricados, no requieren energía para el uso y no requieren mantenimiento a menos que estén dañados. Usar la inflación adecuadamente es la manera más efectiva de reducir el uso de la energía y las emisiones de gases de efecto invernadero.[5]​.

cool covers

Another more efficient way to reduce energy consumption and save money, along with the latest plant-based insulation, is with proper roofing. "Cool Roofing" involves the use of roofs that direct sunlight back into the atmosphere instead of being absorbed by the material and passing into the building. This "cool roof" can save money by reducing the cost of keeping a building cool using only air conditioners. The same process can be used to keep warm and reduce the cost of heating. A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof.[6]​ Cool roofs can be made of a type of highly reflective paint, a sheet covering, or highly reflective shingles.

La incorporación de materiales reciclados en el proceso de fabricación de nuevos bienes es un cambio integral. Los recursos minerales son finitos, como el mineral de bauxita para el aluminio o los combustibles fósiles para hacer plásticos, por lo que es imprescindible comenzar a reutilizar lo que ya hemos minado para que no agotar lo que queda. Hay muchas tecnologías disponibles que ayudan enormemente con los esfuerzos de reciclaje, tales como equipos de infrarrojo-cercano que "es una tecnología de clasificación común en grandes operaciones de reciclado y puede identificar con precisión muchos tipos diferentes de polímeros."[7]​.

Aluminum

Aluminum offers the greatest savings, with cans from recycled material requiring as little as 4% of the energy needed to make the same cans from bauxite ore. Metals do not degrade, as they are recycled in the same way as plastics and paper, the fibers shortening each cycle, many metals are prime candidates for recycling, especially considering their high value per ton compared to other recyclable materials.[8]​.

Plastics

Polystyrene from recycled material costs 88% less than without recycling, but a negligible amount of polystyrene is recycled in the United States due to the difficulty of sorting it from other plastics. Other plastic products, such as polyethylene terephthalate bottles, cost 76% less to manufacture recycled materials, and this percentage, as well as the variety of plastics that can be recycled, will increase with new separation technologies such as foam flotation and skin flotation. [3, 6] However, plastic degrades every time it is recycled, so some plastics will always have to come directly from fossil oils, if we want to continue producing these plastics.

Paper

Paper (particularly newspaper) and glass are less energy efficient than previous materials, with recycled products costing respectively 45% and 21% less energy. Recycled paper has a large market in China, although work still needs to be done to facilitate the recycling of mixed paper instead of newspaper.

If we were to use these recycling methods, we would not have to spend energy and resources mining to obtain new resources for use in manufacturing. Recycled aluminum, for example, has the same properties as newly manufactured aluminum, but uses less energy in the manufacturing process. This assumes, however, that the recycling plants are being run as efficiently as possible.

Con la reutilización de los materiales, se utiliza aún menos energía que con el reciclaje. La reutilización es preferible al reciclaje, porque elimina el costo de transporte a una planta de reciclaje, clasificando, re-fabricando, distribuyendo, y además, no se usan los salarios necesarios para los empleados contratados en realizar estas tareas. Los contenedores reutilizables sólo deben fabricarse una vez por cientos o miles de usos (como una botella de agua utilizada todos los días durante años), y el costo de energía entre usos es aproximadamente el de limpiar el recipiente con agua y jabón, un gasto insignificante comparado con el de la clasificación, fusión y vertido del material en un molde nuevo, por ejemplo. La reutilización de contenedores podría, en teoría, reemplazar contenedores reciclables y recipientes de un solo uso, si están hechos de un material lo suficientemente resistente. Hay, sin embargo, inconvenientes en la reutilización de materiales. Algunos de estos inconvenientes, incluyen tener que limpiar los recipientes entre usos, usando envases llenos o vacíos, y requieren además, un compromiso, debido a tener que aferrarse a ellos, en vez de botarlos a la basura.

glass and paper

For products with glass containers, a deposit-refund system to encourage people to return containers to the store for reuse may seem more useful than recycling, given the durability of glass and the small energy savings for recycling.

Currently there are three types of light bulbs: incandescent, compact fluorescent (CFL) and light-emitting diode (LED). Electric lighting alone can account for around 14% of your current home energy bill.[4]​ In addition to this, only 10 percent of the electricity used by an incandescent bulb generates light; the rest is lost. Below are two comparative tables where the three types of light bulbs are compared:

Another way to reduce electricity consumption and save money with lighting is by installing dimmer switches with these bulbs. A dimmer can increase and decrease the amount of light emitted by the bulb as you like. You can't make a bulb brighter than its maximum design allows, but you can reduce its intensity, therefore using less electricity and saving more money.
