Global warming caused by carbon emissions is both humanity’s greatest challenge, as well as an enormous financial opportunity. Buildings cause over 30% of the world’s carbon emissions, making them the largest singular source of carbon emissions because they consume about 60% of global electricity. More than 70% of all buildings were built before the first energy crisis in the 1970’s, which creates an enormous market for improving their energy efficiency. Bluenote is launching the world’s first blockchain-based energy efficiency protocol. It creates a decentralized ecosystem which allows building operators around the world to learn from one another how to waste less energy through distributed data intelligence. Making buildings more energy efficient has a number of key benefits: - It generates an enormous direct and continuous cost saving by reducing their energy costs. - These cost savings make buildings more profitable and therefore substantially more valuable. Potentially unlocking $6.5 trillion in global real estate value. - The non financial, but sustainability benefit, is that the increased energy efficiency greatly lowers carbon emissions.
