How much power (what percentage) do the Dams along the Columbia really generate? PGE also has a dam operating off the Clackamas river.
Although it has a vast generating capacity, the BPA does not produce enough power for the region. This coupled with public utility districts (PUD's) having first dibs through contractual agreements, leaves PGE and Pacific Power having to generate their own energy to supplement what little they receive from the BPA.
The paying more for renewable energy aspect that both PP&L and PGE offer is somewhat of a joke as they are mandated to have a certain percentage of their generating capacity be green within the next couple of years. Thus, the public is being solicited to pay for something that these companies will have to do eventually anyway. As you astutely point out, the energy all goes into the same grid, and thus this feel good measure is almost duplicitous in that the energy produced from a wind turbine in eastern Oregon, that you are paying for, does not go directly to your house, but rather is simply added to the grid that day.
I saw this info when I got my first PGE bill, asking me to pay more for renewables. I don't think this is a secret at all, unless things people are oblivious to are suddenly "secrets". Secret poverty, secret genocide, and on, all hidden by a conspiracy of reality to not magically populate the mind with information, but actually requiring one to read something. Dastardly!
Anyway, I support pressure on energy producers to switch to carbon-neutral sources, and I support paying more for it, which we will have to do. I do not like the idea of natural gas. It's better than coal, but still contributes to global warming. Maybe we should give the Feds a couple six months to put out some Cap'n'Trade legislation before we decide how to generate our energy? Just a thought.
Having perused the department of energy's website, I have not found the reference to 70 precent aspect being generated by hydro that you refer to. Do you have a specific weblink?
I ask as coming up with this number would be questionable as the western states our all on the same grid (the other two are the eastern grid, and Texas of all things having its own). If we all share the same grid, the statement that Oregon has a specific percentage in generation is arbitrary, and subsequently misleading as it is combined with all the other western states and thus is a moot point.
This having been said, one would then look to a specific provider (PGE, Pacific Power, EWEB, etc.) to see what their generating mix is into the shared grid.
To paraphrase the page, coal supplies roughly 9% of Oregon's energy.
The 40 percent number in the article comes from the Oregon Department of Energy, not PGE. You can download the pdf of their 2007-2009 energy plan confirming the resource split at this website: http:/www.oregon.gov/energy/docs/energypla…
Thanks for bringing up that Portland's energy mix is slightly different than Oregon's as a whole. According to PGE, 24 percent of the energy they provide to Portland is straight from coal sources. But another 20 percent is bought off the market from other provides and that energy is from 15-16 percent coal sources. So energy provided to Portland from PGE breaks down to being about 39-40 percent coal, too.
The numbers quoted in the document you referenced are from 2005. If you go to the (updated weekly) page referenced in my post and look under "Coal, Electricity and Renewables", you will that 2/3 of Oregon's electricity is hydroelectric, 1/4 is LNG, and the rest is split between the remaining resources. No one is arguing that 40% of Portland's electricity is coal-produced, but the title of your article states that 40% of Oregon's electricity is coal-produced, which is incorrect.
If you want to green up your power your choices are: Conserve/Reduce and add solar/wind to the grid. Everything else is rearranging the deck chairs.
