Conservation used to be the coolest thing in energy planning. But now all most people want to talk about is the next great renewable energy source -- wind farms, solar arrays, small-scale nuclear plants, even wave energy.
And while all those sources of energy are promising, the Northwest Power Planning Council's new 20-year power plan is right to go back to the future: It proposes doubling down on the Northwest's long history of conservation to meet 85 percent of the region's new demand for electricity.
It's a smart and bold plan, even if it disappoints the clean-energy activists who have pressured the council to declare the Northwest a coal-free zone.
The most important factor to consider when evaluating the environmental impact of wind generation is that the power source is inconsistent and intermittent. This variability can present substantial challenges to incorporating large amounts of wind power into a grid system, since to maintain grid stability, energy supply and demand must remain in balance.
In order to integrate wind energy, utility companies must provide a power load to meet the base requirements of the population.
Winds of change: Oregon’s charge for clean, green electricity may be neither quite so clean nor quite so green as it first seemed

Electricity is so cool. Always there for us, at the flick of a switch. But where, exactly, does it come from? And what gets hurt on its way? When deciding how to generate power, this much is clear. Oregonians don't like nukes. Too scary. And they don't like coal. Too dirty. They're not even sure about liquefied natural gas. What is that stuff, anyway?
Hydro? Sure, Oregonians used to like hydro. But that was then: before salmon started disappearing by the gazillion. This is now: We're tearing out dams, not building new ones. But wait, here comes the answer: blowing in the wind.
Make that in the safe, reliable, clean, green, free, fish-hugging wind. We all love windmills, right? But hang on there, Bub. What about loving windmills in your backyard?
Just about everyone in the Northwest should be concerned about the potentially devastating effects of climate change.
And just about everyone should realize that there is only one way to head off the environmental disaster looming ahead -- an aggressive combination of improvements in energy efficiency and a major increase in the use of energy sources that do not release global-warming gases. With no possibility of increases in our large-scale hydropower projects and now talk of removing some existing dams, that means an increasing use of the only other large-scale, emissions-free source: Nuclear power.
