The FINANCIAL -- Producing energy requires a lot of water. Yet, the availability of and
access to water is negatively impacting energy production around the
world, according to the World Bank Group.
Last year alone, water shortages shut down thermal power plants in India, decreased energy production in power plants in the United States and threatened hydropower generation in many countries, including Sri Lanka, China and Brazil.
The problem is expected only to get worse. By 2035, the world’s energy consumption will increase by 35 percent, which in turn will increase water consumption by 85 percent, according to the International Energy Agency.
“The world’s energy and water are inextricably linked. With demand rising for both resources and increasing challenges from climate change, water scarcity can threaten the long-term viability of energy projects and hinder development,” said Rachel Kyte, World Bank Group Vice President and Special Envoy for Climate Change.
Part of the challenge for the energy sector is the competing demand for water. This demand will grow as the world’s population reaches 9 billion, requiring a 50 percent increase in agricultural production and a 15 percent increase in already-strained water withdrawals. With two-thirds of the world’s population - or 5 billion people - urbanized by 2030, cities in developing countries will be under tremendous pressure to meet the demand for food, energy, and water services. Yet today, some 780 million people lack access to improved water and 2.5 billion, more than one-third of the world's people, do not have basic sanitation, according to the World Bank Group.
Thirsty Energy is a global initiative aimed to help governments prepare for an uncertain future by:
identifying synergies and quantifying tradeoffs between energy development plans and water use
piloting cross-sectoral planning to ensure sustainability of energy and water investments
designing assessment tools and management frameworks to help governments coordinate decision-making
With the energy sector as an entry point, initial work has already started in South Africa and dialogue has been initiated in Bangladesh, Morocco, and Brazil where the challenges have already manifested and thus where demand exists for integrated approaches.
Failing to anticipate water constraints in energy investments can increase risks and costs for energy projects. In fact, the majority of energy and utility companies consider water a substantive risk and report water-related business impacts, according to the World Bank Group.
The issue is too large for any partner or sector to tackle alone.
“Water constraints on the energy sector can be overcome, but all stakeholders, public and private, must work together to develop innovative tools and use water as a guiding factor for assessing viability of projects,” said Maria van der Hoeven, Executive Director of the International Energy Agency. “The absence of integrated planning is unsustainable,” she added.
Solutions exist, but countries must continue to innovate and adapt policies and technology to address the complexity of the landscape. These solutions include technological development and adoption, improved operations to reduce water use and impacts in water quality, and strong integrated planning.
“We cannot meet our global energy goals of extending access to the poor, increasing efficiency and expanding renewables without water. The water energy interrelationship is critical to build resilient as well as efficient, clean energy systems. The time to act is now,” said Kyte.
