Active search for alternative energy solution & The importance of good habits

The world has changed dramatically over the past 200 years, thanks largely to fossil fuels, coal, oil and natural gas. These provided us with cheap and convenient energy that we use to heat and cool our homesand run our cars, appliances and industries.

But there has been a cost. No city in the world is immune to the effects of polluting fossil fuels, and contribute vast amounts of gases into the atmosphere, which many scientists believe to cause global warming.

In the past decades scientists have been looking for ways to produce energy without adverse side effects. Promising renewable energy sources such as wind, sunlight and biomass are discussed among other new alternatives. It may pass a few years before these energy sources have a big impact, but they illustrate the diversity of options that are available.

With that goal in mind and aware of the consequences of what we can leave to future generations that we operate continuously in the search and transmission of information on alternative solutions.

Good habits start at home, it only takes a family or community to make a difference. Most people who show no interest in what you’re doing, are to repair and learn from you, sooner or later they will pass your habits, and make a difference.

Start by separating recyclables such as plastic, paper, glass, and metal, you’ll see that then you will be making a habit, it costs a few seconds of your life and gives many years to our environment.

01. Rethink: Seriously rethink habits. Think carefully before buying. Choose to buy only what you really need. Excessive consumption causes environmental degradation.

02. Refuse: Refuse products manufactured by a company that does not respect nature or harms the environment. Choose to buy from those who produce with low impact on the environment and benefit society.

03. Reduce: Correctly using products with greater durability and packaging in the right measure will reduce energy consumption, water consumption, and the amount of residual waste. So, when buying something, think about how to reduce the amount of waste that will be generated with what you buy and avoid excess consumption.

04. Repair: Often, a broken product is cheaper than a new repair. In addition to being sustainable, you still save.

05. Reuse: Use the same package several times. With a little imagination and creativity, we can take advantage of materials for other functions.

06. Recycle: Transforming waste that was previously useless into raw points or new products is a benefit both from an environmental and energy point of view.

07. Reintegrate: What cannot be recycled, such as food waste and other organic materials, can be reintegrated into nature.

We are present in 8 countries and 5 continents.
