Investment in energy transmission infrastructure can prevent or minimize the impact of future blackouts and brownouts, yielding further protection for 529,000 jobs, personal incomes, GDP, and US exports. Finally, investment in surface transportation infrastructure can both create millions of jobs and protect existing positions, save nearly 2 billion hours in travel time, save each family $1,060 per year, and add $2,600 in GDP for every person in the United States.

The American Society of Civil Engineers (ASCE) has for several decades issued a report card for America's infrastructure; the last one came out in 2009 -- and for 15 categories of infrastructure assigned an average grade of D.2 Consider these facts: • Leaking pipes lose 7 billion gallons of clean treated drinking water each day.

Water Many regions in the United States are juggling competing needs for water between municipal and domestic users, agricultural and industrial users, and the environment. Population growth, urbanization, and climate change will continue to stress water resources and accelerate the need for new solutions to conserve, supply, treat, store, and distribute water.

• Develop new sources of water, such as desalination plants, tertiary water treatment for recycled water use, or rainwater collection treat ment and redistribution systems. Energy The main sectors of energy consumption in the United States are electric power generation, which is the largest at 40 percent of the total, followed by transportation at 28 percent, industry at 20 percent, and residential at 11 percent.

Sustainable transportation systems help lower the number of transportation-related deaths and injuries and significantly reduce negative environmental impacts by, for example, decreasing greenhouse gases and other harmful air emissions. INVESTMENT Engineers play a unique role in the built world -- planning, analyzing, designing, building, and rebuilding things that touch the planet -- and therefore have an optimal and natural role in changing the built environment to meet new needs.

However, an additional $84 billion invested between now and 2020 could help prevent those increased costs to businesses and households, and protect 700,000 jobs, $541 billion in personal income, $460 billion in GDP, and $6 billion in exports. In terms of electrical transmission, an additional $11 billion per year between now and 2020 could prevent blackouts and brownouts that cost businesses $126 billion and households $71 billion (Figure 3)

This investment would create millions of new jobs, protect a million existing jobs, save nearly 2 billion hours in traffic time, save families over $1,000 a year, and add $2,600 in GDP for every person in the United States. Figure 5 summarizes some of the key results of the "Failure to Act" reports.

54 LIVABLE CITIES OF THE FUTURE CONCLUSION Engineers are at the forefront of the nation's infrastructure upgrades, with a critical opportunity to approach infrastructure repair, enhancement, and construction in new ways that incorporate sustainability and resiliency to make existing and emerging cities and megaregions smarter and greener.
