Somos una empresa enfocada a la Eficiencia Energética y la Cogeneración con Sistemas Solares para industria y comercio principalmente. About Us We are a company with different lines of business, all with a focus on real estate and sustainability, derived from the professional experience acquired by the founders and the need of our clients to build, maintain or improve the efficiency of their properties. We have developed other lines of business which allows us to provide a greater and better solution for each industrial or commercial project. The Story We were born in 2015 with a clear focus on Energy Efficiency solutions in the industry, at the height of environmental awareness and carbon footprint reduction. We were excited by the recent shift to LED, which was geared towards efficiency, design and regulations , and also driven by the UN agreement in Paris that same year (2015) where 196 countries agreed to limit global warming to less than 2°C (ideally 1.5°C) above pre-industrial levels. This consolidated the idea of reducing the carbon footprint as a global commitment to the UN Sustainable Development Goals (2030). As well as, derived from the real possibility of installing solar panels with the recent launch of the CFE interconnection contract for distributed generation systems, in 2014. And finally motivated by Tesla's greatest discovery, alternating current , which enabled the electrification of rural and urban areas around the world, facilitating access to electricity for millions of people . Which gives rise to our name and brand EALTERNA® . Founding team At EALTERNA, it all began with a simple but powerful idea: to offer sustainable energy solutions. With dedication and commitment, our founders, with extensive experience in infrastructure and maintenance projects for the industry, have worked to make that vision a reality. Their experience in developing large projects allows us to guarantee efficient and reliable solutions for the future. CEO & Founder Antonio Salinas Passionate about offering cost-effective solutions with the best and fastest possible implementation under a planned project management to obtain the expected results. He believes that a committed and well-communicated team is the key to project success. CSO & Cofounder Horacio Tello Always seeking to gain the trust of customers, listening to them and offering the most appropriate solution for each need, he considers that each client is a new, very important relationship for him and for the company.
