Optimal energy mix for the future.
Creation of a stage where each and every person can lead a rich life.
All the energy we need to live comes into this world from Mother Nature. For this reason, if we choose the excessive pursuit of comfort and convenience, we will face difficulties in maintaining and protecting the recycling-oriented society and environment from ancient times, which may threaten to close the road to the future. Prospec AZ Inc.(PR-AZ) is in the business of creating the infrastructure needed for each and every person to lead their lives and for society to develop based on renewable energy. One of our philosophies is to supply only the amount of energy needed for the development of each region, such as Japan, Asia, Europe and North America, in the most appropriate way possible, rather than achieving happiness in exchange for the environment that has been nurtured. PR-AZ will continue to form an optimal energy mix based on waste-free power generation systems and supply systems that have been tailored to this.
What we seek is the creation of a Smart City that fulfills the dream of a recycling society in which there are no by-products and waste resulting from power generation. As well as the foundations for daily life, PR-AZ also creates the industries needed to develop an economic foundation, as well as cultural activities to help people live even richer lives.
The future of PR-AZ is here as we aim at the formation of healthy and sound societies and lifestyles in anticipation of the next 100 years.
