Renewable sources in the energy matrix are indispensable.

Our energy matrix is mostly made up of non-renewable sources, although the electricity portion of it can be 90% fossil-free.

According to the characteristics of sustainable development, which must simultaneously promote the social, economic, and environmental elements in a viable, viable and equitable way (ECLAC, 2018), the sustained inclusion of renewable sources in the energy matrix is vital. 

The United Nations has proposed an action plan based on 17 goals to bring us closer and closer to the goal of sustainability. One of these goals (number 7) proposes to ensure access to affordable, reliable, sustainable, and modern energy for all. 

In the same way, other efforts converge in the achievement of a common goal based on Peace and Environment. The energies that are having the most development at the moment are wind and solar. Both types of power are intermittent and cannot be used as base power in an interconnected system. 

This energy roaming could cause disturbances in the network strong enough to generate problems at the level of distributors and consumers, although for this to be perceptible in an interconnected system, a high percentage of participation is required (which is not even visible today).

In regions such as Australia or the Hawaiian Islands, the excessive incorporation of solar systems and other itinerant systems has led to the growth of another large renewable industry, that of storage and regulation.

Although we have already gone through the energy era of solids (such as coal), or liquids (such as oil); Gas has yet to be developed on a massive scale. It is certain that this source will be the main global energy base in the not-too-distant future, of course, followed by wind and solar. These three energy sources will be a global pillar and will contribute to the reduction of GHGs. 

However, to achieve these objectives, the problems of stability and energy management that they entail must be addressed. It's where energy administration, management, and storage systems shine. 

Pumping systems, lead and lithium accumulators, and others such as green hydrogen are being developed, each at a particular point of performance, but all in the end in a common struggle to face the challenges of a very dynamic and democratic matrix.

The growth of distributed generation and consumer producers is inevitable. This formula is the basis for achieving the energy goals based on the 2030 agenda that we already have around the corner.

In the face of this exponential growth, it remains to adjust to the market responsibly and efficiently. For this reason, the country must train more professional designers and much more installation and maintenance personnel.

There are several areas of action in this regard. For example, the Chamber of Distributed Generation has published (for its members), a manual of good practices, which is basically a pocket extension of the National Electrical Code that is based on the NFPA70/NEC2014. 

Likewise, some other entities such as electricians' associations, technical universities, and professional associations, are taking provisional measures in this regard and are generating action plans to be able to continue with this growth safely.

We can all be part of this change, but let's do it responsibly.
