Water and Energy for a Sustainable Future

MEETING THE WATER AND ENERGY Those who lack access to improved water and sanitation are also likely to lack access to electricity, and rely on solid fuel for cooking. The health consequences are devastating: Indoor air pollution is linked to respiratory disease, and the lack of safe drinking water and sanitation can result in chronic diarrhea. Women and children represent disproportionately high fraction of the unserved. NEEDS OF PEOPLE AND SOCIETIES WATER 768 million people don't have access to clean water The world population is increasing by 80 million people each year AND ENERGY ( 3.5 billion people's right to water is not satisfied for a sustainable future By 2050 the world will need: 2.5 billion don't have Access to water and energy are essential to strengthening human dignity and to the development of people and societies. We must find new ways to save water and energy and optimize our modes of production and consumption. We need to produce more with less. access to adequate sanitation + 60% food +55% water PRODUCING ENERGY 1.3 billion have no electricity FROM WASTEWATER +100% electricity +70% Innovative ways of producing energy from wastewater energy 2.6 billion use solid combustion - essentially biomass - to cook THE CHALLENGE WILL BE GREATEST WHERE THE WATER-ENERGY NEXUS WATER RESOURCES, INFRASTRUCTURE AND SERVICES ARE INADEQUATE OR SCARCE 4 The water treatment plant La Farfana treats 50% of wastewater of Santiago (Chile) and produces about 24 million liters of biogas. This energy, which replaces natural gas, benefits 100 000 people of the Santiago region In Stockholm (Sweden) buses and taxis use biogas produced by wastewater plants WATER AND ENERGY ARE HIGHLY INTERCONNECTED AND INTERDEPENDENT THE COST OF PROGRESS What's needed to achieve universal water/energy access : Not estimated ALL WATER SERVICES REQUIRE AN INPUT OF ENERGY. ENERGY PRODUCTION ACCOUNTS FOR 15% OF THE WORLD'S TOTAL WATER WITHDRAWALS. Little or no water scarcity Physical water scarcity Approaching physical water scarcity This average should increase by 20% from now to 2035 - Producing more energy comes at the cost of water An extra $49 billion per year needs to be invested to achieve universal energy Additional partners, including the private sector, can help Economic water scarcity close the infrastructure GLOBAL PHYSICAL AND ECONOMIC WATER SCARCITY 90% of all electricity generation is water intensive 80% of the world's access by 2030 financing gap electricity is generated by thermal power ENERGY CONSUMPTION PER CAPITA FOOD FOR THOUGHT $103 billion per year would have been necessary to finance water sanitation and treatment from 2000 to 2015 WATER AND ENERGY: A TWO-WAY RELATION :0: aln: 8 UN WATER Report IIESCO United Nations Educational, Scientific and Cultural Organization The United Nations World Water Development Report 2014 Water for energy Energy for water WATER AND ENERGY The contents of this infographic In several areas where freshwater resources are scarce or limited, a growing number of water desalination plants have been developed to cope with increasing demands for water, and these require lots of energy To diversify and enhance their energy supplies, certain countries have turned towards alternative and have been extracted from the VOLUME 1 United Nations World Water ANNUAL CONSUMPTION Development Report (WWDR) 2014.

Globally the demand for water and energy is soaring. Yet in many parts of the world, people live without access to either. Our infographic shows how we can bring water and energy to all, through col...
