6.A. - Page 56 of 251 Strategies and Actions Connection between Energy and Water Use Energy and water use are linked. Energy is needed to transport and to treat water, treat wastewater, and heat domestic hot water in homes and businesses across California. Approximately 20 percent of California's electricity and approximately 30 percent of natural gas used by homes and businesses across the state is dedicated to pumping, treating, and heating water. Figure 13 indicates the 10 percent of energy used to transport and treat water; energy used to heat water is distributed among the various customers.

Over time, emissions associated with each kilowatt hour of electricity generation in California have continued to decline as the grid relies less on fossil fuel power generation sources, including coal and natural gas, and more on renewable power generation sources, including solar, wind, and hydropower. In Redwood City, natural gas accounted for 67.5 percent of building emissions in 2017, while electricity accounted for 32.5 percent of building emissions. Electricity emissions in Redwood City have decreased 65.4 percent since 2005 and natural gas emissions have increased 2.7 percent, but have been in a period of decline from 2010-2017. With the launch of Peninsula Clean Energy, which has a stated target of all electricity sales being 100 percent GHG- free by 2021, and the State's requirement through Senate Bill 100 (SB 100) that utilities procure 100 percent of electricity through renewable resources by 2045, the percent of building emissions associated with electricity will only continue to decline. The State of California remains a leader in implementing policies aimed at reducing water consumption. Assembly Bill 1668 (AB 1668) and Senate Bill 606 (SB 606), adopted in 2018, require urban water providers to establish a City of Redwood City Climate Action Plan 45 361 a f� 3 Cr {6 N p 3 {6 :J Residential Use BreaRcrown s - Shower Bath Clothes Faucet Leaks Dishwasher 149 2% YVasher 130/. 1°% 30% 9% How Are We Doing?
