Proven savings at the energy-water nexus are stepping into the spotlight
NITI Aayog’s Composite Water Management Index (2018) highlights that 75% of households in India lack drinking water on premise and 70% of India’s water is contaminated. Integrating water and energy efficiency in solutions to provide 24x7 clean water and sanitation will help curtail the associated increase in municipal and residential electricity demand. Weston Berg of the American Council for an Energy-Efficient Economy, the premier policy think tank on Energy Efficiency in the US, throws light on integrated approaches to water and energy efficiency in the US.

World Energy Outlook 2018: Water-Energy Nexus
Interational Energy Agency
Energy supply depends on water. Water supply depends on energy. World Energy Outlook found that in 2014 some 4% of global electricity consumption was used to extract, distribute and treat water and wastewater. It also highlights a range of potential synergies between Sustainable Development Goal (SDG) 6 on water and SDG 7 on affordable and clean energy. For instance, taking water supply needs into account when planning electricity provisions in rural areas can open different pathways for both, which in turn can bring down the cost of electricity for households.
Integrated pathways for meeting climate targets and ensuring access to safe water
International Institute for Applied Systems Analysis
Energy is vital to water and sanitation provision, for example in water pumping and treatment, while the energy sector is itself a large consumer of water, for example in power plant cooling and fuel processing. Reducing emissions from energy is key to achieving the Paris Agreement, therefore the research, which quantifies the interactions between the Paris Agreement and SDG6, will be useful to policymakers developing strategies for joint implementation.
Workshop highlights conservation of water, energy
The Tribune
The workshop aimed to increase awareness about the various interventions which can be adopted by farmers to save water and energy for sustainable agriculture.
Improvements in Water Desalination Tech Lead to Energy Savings, Market Growth
Environmental Leader
The market for water desalination pumps will register a CAGR of more than 6% by 2023, with growth being driven by regulatory changes and the increased need for energy efficiency.The governments of several countries such as the US, India, and Saudi Arabia are focused on increasing the energy efficiency of desalination technologies through applied research and science.
Tata Power seeks to tap Delhi EV charging as demand growth slows
The Economic Times
Tata Power Co. is seeking to set up electric vehicle chargers in the Indian capital, a company official said, as one of the most polluted cities on earth plans an ambitious push toward cleaner vehicles.
Smart meters will tell you when it is cheaper to run heavy appliances
The Times of India
Smart meters and associated mobile app will soon transform the way domestic consumers use electricity by allowing them the option to run heavy appliances such as washing machines or press clothes when tariffs are lower, such as during off-peak hour.
Blockchain and energy
The Hindu BusinessLine
On the transmission and distribution side, blockchain can facilitate central monitoring and control systems to form “Virtual Power Plants” (VPP). With increased transparency and immutability, VPPs can enhance grid security, process efficiency and lead time reduction for energy transactions.
Micro and Mini Grids Could be the Answer to Grid Stability and Reliable Power in India
Mercom India
The market for microgrids is still in its nascent stage and as of January 2018, 63 solar microgrids totaling 1,899 kW had been installed in the country. For rural India, these are ideal, as communities tend to be spread across large areas, and therefore localized systems are likely to work better.
