In today’s age of technology developments and exciting advances, there is still a population of up to 1.3 billion people living without access to electricity. The IEA, or International Energy Agency, shows that “this is the equivalent to 18 percent of the global population and 22 percent of those living in developing countries.”
While this is true, though, the world recognizes that energy is essential to economic development. UN studies have stated, “Energy provides mobility, heat, and light; it is the fuel that drives the global economy. But the production and use of coal, oil, and gas cause air pollution and climate change, harming public health and the environment.”
In response, studies have been made to find the most cost-efficient way to provide eco-friendly energy sources. The new power source that is currently being tested comes in the form of human waste.
To show the true potential of the source, the United Nations University created a study to find the value of human waste in terms of energy.
The study showed that “biogas from human waste, safely obtained under controlled circumstances using innovative technologies, is a potential fuel source great enough, in theory, to generate electricity for up to 138 million households – the number of households in Indonesia, Brazil, and Ethiopia combined.”
With that number in mind, the UNU’s Institute in Canada estimated “that biogas potentially available from human waste worldwide would have a value of up to US$ 9.5 billion in natural gas equivalent.”
The waste would be dried and charred, producing a sludge-like substance similar to coal but with the added bonus of being eco-friendly.
With all of these facts, however, the concept is still a major taboo in people’s eyes. To combat this, experts have shown that the world already reuses water and nutrients from wastewater and continue to fight for the new energy source potential.
With World Toilet Day on Nov. 19 being around the corner, the U.N. hopes to combat the stigma. UNU-INWEH Director Zafar Adeel stated that it will hopefully “promote new thinking and to continue puncturing the taboos in many places that inhibit discussion and perpetuate the disgrace and tragedy of inadequate human waste management in many developing world areas. This report contributes to that goal.”
