Grid parity is the point at which alternative means of generating electricity are equal to or cheaper than grid power.
Reductions in production costs are driving some of the increase in market share for renewable energy, Frantzis said.
"With the federal and state incentives in place, [renewables] are very competitive with existing technologies today," she said.
Another major driver: the price of natural gas, which could derail the competitiveness of renewable technologies.
"We do see the price of natural gas going up -- probably not as much as we expected -- because of the shale gas now available," she said.
A 25 percent renewable energy standard can result in significantly more U.S. jobs supported by the renewable energy industry, Frantzis said.
"The key takeaway here is that if there were a 25 percent standard in place, there would be 274,000 more jobs by 2025," she said.
She also said that after a 50 percent compound annual growth rate globally for last five years, the forecast is unclear, thanks to "strong influence" from a German feed-in tariff that may not continue and "uncertainty" of what will unfold in China and India.
A feed-in tariff is a policy to help accelerate the adoption of renewable energy. Much like an on-ramp to a highway, the tariff helps renewable energy sources enter the market by tying the purchase prices of "green" electricity to the cost incurred to generate it. Long-term contracts ensure that utilities buy the power.
"There are some unknowns that can drive this thing one way or the other," she said.
Diving into the solar market, Frantzis said U.S. demand for photovoltaic solar power is expected to grow between 31 and 46 percent over next five years -- that's more than the global rate -- and drive the market from only 0.48 gigawatts to 1.8 to 4.9 gigawatts of capacity.
Grid-connected markets currently dominate U.S. market applications, with a 92 percent market share, she said. That includes utility, commercial and residential, though the utility slice of the 475-megawatt total in 2009 remains small.
One upside, however: utilities now qualify for the 30 percent Investment Tax Credit through 2016. "That makes it very competitive," she said.
Third parties are also in the mix, Frantzis said. "They're getting into it just to get the operational experience just in case this takes off."
Moving to the wind power market, Frantzis said there's "no question" that it's a large one, with an installed wind power capacity in the U.S. of 35,603 megawatts thanks to the addition of 10,050 megawatts in 2009, mostly in Texas, California and Oregon.
One cautionary note, however: a production tax credit could expire at end of 2012. Frantzis said that if the federal incentive isn't renewed, the wind power industry will drop from 8,000 megawatts to 2,000 megawatts per year.
Transmission issues are also "a critical piece" for the wind industry, she said. About 35 percent (or 11,000 mi.) of 200 kilovolts-or-greater lines will be needed for renewables integration, Frantzis said.
"This is needed," she said. "There is recognition that it's needed. You've got to run resources to the load centers."
Above all, it comes down to jobs creation, Frantzis said.
"There's tremendous opportunity out there," she said. "Natural gas prices and jobs creation will play a significant role in increasing market share [of renewables]."
Also among the panelists was CERES president Mindy Lubber who stressed that the issue of climate change was the true driver of the renewables industry.
"If every one of us in this room is not acting to have an influence on public policy -- and I would argue to put a price and cap on carbon pollution -- than we are not acting to influence the most profound market driver," she said.
"Can we separate climate and renewables? We can't separate them. I think climate is a huge driver from the perspective of financial policy, practical implications for the industry."
Overpopulation is also an issue, Lubber said. (That would seem to be in line with what legendary animal expert Jack Hanna told us in May. --Ed.)
"We live in a world where there are six billion people going to nine billion people," she said. "We don't have the resources. We also know that every day we are seeing more black swan weather events -- whether it's the Gulf or the increase in tsunamis or the earthquakes -- profound things that have an impact on our economy."
The increase in greenhouse gas emissions is causing events that cost companies millions or even billions, Lubber said.
"We're seeing a continued rise in CO2," she said. "Many companies are continuing to emit more and more carbon. The collective implications are clear: we need to change our energy mix, we need to build an energy infrastructure to be able to bring our carbon footprint down. We need to focus on the most important economic policy driver."
That starts with honest accounting and putting a price "on things that cost our society real money" -- carbon.
"Right now we are saying that carbon pollution costs us zero," she said. "We do not have a price on carbon pollution here in the United States. When something is free, you get more of it. And we are getting more of it."
"Putting a price on carbon and putting a cap on carbon is perhaps the most important thing we can make happen [to help the renewables industry]."
