You can't miss it -- 213 solar panels and a battery the size of a tractor trailer sit alongside one of Duke Energy's electric substations on Charlotte, North Carolina's Highway 51.

And that is intentional, said Paige Layne, Duke Energy's corporate communications manager. "We found because the solar panels are out there on one of the busiest highways in Charlotte, people call in and ask us about them."

Duke Energy's chief executive doesn't mince words.

It was early May, under stormy skies, when Jim Rogers gave the opening keynote, "Smart Grid: The Catalyst to Transform the Energy Sector," at the Smart Grid Roadshow in Cincinnati. Later that morning, he followed up about his vision for the utility industry. One of his key messages: Keep educating the customer, and pay attention to the customer's wants and needs.

"As we design products for customers, it's important to listen to what the customer wants," Rogers said. "But it's also important to notice that the customer doesn't necessarily know what he wants yet."

Juggling four bowling pins is difficult enough, even for the polished entertainer.

But add four more pins to the mix, then light one or two on fire, and you might grasp a clearer understanding of the daunting demands facing California's investor-owned utilities as they navigate toward the smart grid of the next decade.

"If you look at all of the policies and directives, 2020 is a really important year for us," said Mike Montoya, director of grid advancement at Southern California Edison (SCE). "We're going to have to do a lot of things differently than we are today. It's going to be a challenge."

Hydropower may be green energy's forgotten cousin. But industry representatives are keen to push it hard now that the U.S. Congress is grappling with energy legislation. They say that hydro holds great potential, noting that despite being an emissions-free source only 3 percent of 79,000 U.S. dams are capable of producing such energy.

Producing electricity from dams is one way to increase the hydro sector's prominence. Generating power from smaller hydro units is another way. Such facilities are less disruptive environmentally but useful in supplying electricity to remote areas. All told, researchers say that almost 60 percent of the nation's water energy resources are potentially available for development using new technologies.

Efforts to enact legislation that would limit carbon emissions have seemingly stalled. So it would appear that new standards to make the transmission wires more amenable to transporting green electrons are untimely. But those who are in charge of ensuring the dependency of the electric grid say that such measures are vital.

The essence of the argument presented by the North American Electric Reliability Corp. is that climate change initiatives are ongoing and that utilities are already incorporating those standards into their business plans. As such, if greenhouse gas emissions are to be cut, then it would require those power companies to diversify their generation portfolios and to offer more sustainable energy.
