In the name of fighting climate change, solar, geothermal, wave and tidal energy are getting a new look
By LISA STIFFLER
P-I REPORTER
The Northwest is spoiled.
Since the first hydroelectric dam was completed on the Spokane River in 1885, a steady flow of water has provided cheap, clean power to the state. This resource doesn't produce planet-warming pollution and renews itself each winter with snow and rain.

But the region can't rest on its hydroelectric laurels alone. There are too many people, too many businesses, too much demand for new juice.
Over the next two decades, energy demand could surge by 13 percent.
Where will the supply come from?
The best stretches of the region's rivers have been dammed. Turning to fossil fuels such as coal and natural gas is increasingly unpopular. Leaders and residents are calling for reductions -- not increases -- in greenhouse gas emissions in an effort to avert a climate crisis.
Initiative 937, narrowly passed by voters last fall, is the road map for Washington's energy future.
It provides the destination -- the state's 17 largest utilities must set aggressive goals for conserving power, and must, in phases, generate 15 percent of their electricity from renewable sources by 2020. The initiative hints at how to get there, by specifically naming the types of renewable energy that are acceptable, and those that don't count.
"This is the fork in the road on climate," said K.C. Golden, policy director for the non-profit Climate Solutions. "Public awareness is there, business and utilities awareness is there that we need to turn from the high emissions path to the low emissions path."
How do we do that?
The specific course to clean energy remains unclear, despite I-937's guidelines. Wind has taken off as the front-runner in our state's renewable resources, but solar, geothermal, wave and tidal, and even poop power from manure -- all of which were championed mostly by hobbyists and inventors up to now -- are getting a serious new look. They all have tremendous potential, but there are drawbacks to each.
In fact, I-937 itself has problems.
Critics worry about the cost of implementing the initiative while others complain that its goals are too timid, weaker than measures adopted in other states.
The new national eco-energy mantra is "25 by 25," meaning 25 percent of power from renewable sources by 2025. Oregon recently adopted those goals. In fact, more than half of the 23 states with renewable requirements reach higher than Washington's 15 percent.
Overarching goals -- such as Gov. Chris Gregoire's aim of reducing carbon dioxide releases statewide by 50 percent below 1990 levels by 2050, or Al Gore's even bolder national target of 90 percent reductions -- trump the cuts required in the initiative.
Weaning consumers off fossil fuels is going to be tough. A recent study by the Electric Power Research Institute said reducing the power industry's greenhouse gas production to 1990 levels will take until at least 2025 -- even if nuclear power production were increased fivefold and wind and solar power were doubled.
The research group, funded in part by electric utilities, warned in a recent presentation: "The challenges to actually achieving these reductions are daunting in their scope and complexity."
Washington faces unique challenges. The state gets more than two-thirds of its power from hydroelectric dams -- a source that's not included in the acceptable renewables list in I-937. Initiative supporters said that's because they're targeting new energy development and the best dam sites are gone. The measure also excludes nuclear power as well as coal plants that promise to one day catch and dispose of carbon dioxide pollution.
Environmentalists are undeterred by the difficulties.
"We have to severely slash our emissions," said Marc Krasnowsky, spokesman for the Seattle-based Northwest Energy Coalition. "That means we're really going to have to switch to efficiency and clean renewables, far beyond what 937 requires, or the 25 by 25.
"Are we doing enough? We've only begun."
Difficult to add up the costs
Embracing green power will either break the bank or save money and the environment. It depends on who you ask.
I-937 supporters see an Earth-friendly future free of oil and coal pollution.
I-937 detractors see an energy debt that could dull the state's economic competitive edge.
In truth, the exact costs of the measure are far from known -- its first goal for renewables is more than four years away.
Some folks already are anxious.
"We are convinced that we're going to see higher power bills," said Chris McCabe, a governmental affairs director for the Association of Washington Business, a non-profit group that lobbies for business interests.
Renewables "are going to cost more and they're going to raise rates," McCabe said.
It's true that renewable energy costs can be many times higher than power from traditional sources. For solar, utilities might have to shell out 10 to 20 times more money per kilowatt-hour compared with the cost of power from existing dams. The price of building wind turbines and coal plants is roughly comparable, though some estimates put wind higher.
But if you wait five minutes those costs could change.
Supporters of green energy expect prices to improve with the adoption of state and national renewable energy requirements, creating a more predictable marketplace for investors and new companies -- though they admit the increased demand also could bump prices up, at least initially.
Federal tax credits defray the costs of wind and solar power, keeping those resources ahead of the pack. Rep. Jay Inslee, a Washington Democrat and a prime backer of I-937, is pushing for improved tax breaks on other technologies, such as wave, tidal and geothermal power.
Eleven years ago, lawmakers here approved sales tax exemptions for the purchase and installation of equipment that makes power from the wind and sun. There are additional programs to support investment in renewable energy at the local level.
The greatest windfall for renewable power could be the creation of a fee that penalizes the production of greenhouse gases. Congress is considering a carbon tax, which would put a premium on the generation of polluting power from fossil fuels.
And if all else fails, I-937 has an escape clause. A utility is in compliance with the initiative once it spends 4 percent of its annual revenue on renewables -- even if it doesn't reach the percentage goals. There are financial penalties for utilities that miss the mark.
Green-energy innovators
The quest for new power sources inspires grand comparisons with some of the nation's most historic technological achievements -- the Wright brothers' first flight, putting a man on the moon, the Internet.
"Within the lifetime of this initiative, things are going to become possible that we don't foresee right now," said Golden, from Climate Solutions. "When you put in place a very strong policy commitment ... you unleash a lot of investment and innovation."
Inslee envisions the Northwest leading the green energy innovations. At a recent news conference, he predicted the region will become the Boeing of wave and tidal power, and said that 20 percent of total U.S. energy needs could be satisfied from this approach.
Puget Sound area utilities already are exploring a range of options. Snohomish County Public Utility District is studying the potential for tidal energy. Seattle City Light has geothermal energy and power from the gas released by decaying landfills at the top of its to-do list. Puget Sound Energy is looking to increase its already sizeable number of wind turbines and is considering biomass projects that turn waste into watts.
It appears that micro ventures will have a role to play, too, including wind and solar installations at homes and businesses that feed energy back into the grid. Dairies and regional sewage treatment plants are getting into the game with small-scale operations that trap methane for electricity production.
Important changes are afoot. It will require experimentation and risk-taking to fuel the revolution demanded by I-937. But in a Northwest outgrowing its supply of electrical juice, on a planet where fossil fuels are wreaking environmental havoc, clean and green is no longer an impossible dream.
"We need to get beyond our comfort zones," Inslee said.
