The first example relates to the predicted increase in the number of electric cars in California:
A typical Santa Monica circuit, which serves about 10 households, may be overloaded should two or three of those customers charge vehicles simultaneously, even if they do so overnight during off-peak hours, Ted Craver, Edison’s chief executive officer, said in a phone interview on Oct. 20.
While surplus power is available at night at cheaper rates, the grid needs adjustments to handle such charging, Craver said. For example, additional or larger transformers may be needed in neighborhoods with numerous plug-in car owners.
In the second example, Science magazine describes the potential impact of biofuel production on the water distribution infrastructure:
Making matters worse, other U.S. energy sectors are growing and increasing their demand for water. Another recent report from Argonne by Deborah Elcock, an energy and environmental policy analyst, for example, found that water consumption for energy production in the United States will jump two-thirds between 2005 and 2030—from about 6 billion gallons of water per day to roughly 10 bgd—driven primarily by population growth. About half of that increase will go toward growing biofuels.
