Ten Years to Renewables Totality

Posted August 18, 2008 8:00 AM

Former U.S. Vice President Al Gore has called on the nation to become totally reliant on renewable energy by 2020. The Nobel Peace Prize winner, now a cleantech venture capitalist, said the key to solving economic and environmental challenges is to stop burning carbon-based fuels. A national electric grid is envisioned to transmit power from solar and wind farms nationwide and to provide infrastructure for plug-in electric cars. Some industry experts say that these these lofty goals are attainable in the 10-year time frame. However, the required expenditure of capital and materials seems daunting, considering that renewables currently comprise only about 8% of national electric capacity. Is this renewables target reachable and realistic?

Ronwagon--I apologise for not citing source on the the windmill versus wind generators--Since I read your post, taht makes perfect sense and I have altered my typing and I am a changed man forever, thanks.

I think it's incumbent on us to think out of the box. Al Gore might be making political brownie points (and getting rich) by bringing these issues to the forefront in a doomsday format.... but.... so what. The earth will change whether Gore likes it or not. It's the lunatic fringe that pisses me off. Because they have become the 'true believers' without the benefit of critical thought the issue becomes one of faith.

"An Inconvenient Truth" just might be Gore trying to empiricize on some rudimentary data that those in the knowhow consider to be nothing less than sociology 101.

Something to consider as we seem soooo desperate for new/renewable sources in energy.

This is a copy paste from a new thread:

http://cr4.globalspec.com/thread/26697/Price-construction-of-windturbines

State line was and is a Florida Power & Light project in Washington and Oregon--Seattle City Light has contracted to buy some or all of the power--Seattle City Light web page claims construction cost to be at $2 million a MW--Within reasonable distance of $3.6 per 1.5MW.($2.4/MW)

Something interesting: John Day Dam output-in megawatts is twice that of Bonneville Dams'(Almost exactly twice) JJD-2160MW, and Bonneville-1084.9MW.

The John Day Dam is upstream, two dams and has a height of 183'(The Dalles Dam is between them). Bonneville is 197' tall.

1075.1 MW difference--The Wind, White Salmon, Klickitat and the Dechutes rivers enter the Columbia after the John Day Dam. These are all substantial rivers and are not taken into consideration. The John Day Dam was built between 1959-1968. The Bonneville Dam was built from 1933-1943 for an output of 526,700MW and in 1974-1981 had a second power house built that more than doubled the output(558,200MW).

NOW--By Buznegs construction cost of $2.4 million a MW--This represents $2,580,2400 or my $2,150,200,000. That is 2.58 or 2.15 BILLION DOLLARS.

This is ONE dam and a conservative estimate and is based on technology differences of 1968 versus 1943 and 1981.

We could remodel/rebuild one dam and affect very little and there is enough potential gain to offset 10 huge wind farms. (based on 35%,out of the 30-35% figure published in the wiki info for state line)

100% grid penetration--Roll On Columbia Roll ON.

I think people should get a choice--If one wants wind power, they should get it and that's all, and they should be required to live where the generators are.

I am curious what you think.
