Nuclear reactor Vogtle 1 at August shut down

Nuclear really more reliable than wind or solar? What’s with the unscheduled shutdowns?

Colin McClelland reported for Bloomberg 21 April 2011, U.S. Nuclear Output Falls as Vogtle Reactor in Georgia Shuts

U.S. nuclear-power output remained near a 4½-year low for a fourth day as the Vogtle 1 reactor in Georgia shut down unexpectedly, the Nuclear Regulatory Commission said.

Power generation nationwide decreased 538 megawatts to 71,781 megawatts from yesterday, or 71 percent of capacity, the smallest amount since Oct. 22, 2006, according to an NRC report today and data compiled by Bloomberg. Twenty-nine of the nation’s 104 reactors were offline.

Southern Co. (SO)’s 1,109-megawatt Vogtle 1 reactor automatically tripped offline yesterday at 5:34 p.m. when it was at full power. The cause is under investigation, the NRC said.

The shutdown was ironically two days after an NRC public meeting “to discuss Plant Vogtle’s annual safety evaluation and assessment.”

That would be the same location where, according to Tice Brashear back in 18 March 2009: Continue reading →

Conversation for jobs —Cristobal Serran-Pagan @ VCC 7 April 2011

Dr. Serran-Pagan suggests we have a conversation among all types of people and do the math. Let’s put the money where it will produce jobs. Solar, wind, why haven’t we been doing it? Real clean renewable sources of energy. He brings up the water the biomass plant would use.
Water is precious. Air is precious. Oil, coal, is not precious. Biomass is not precious. We have plenty of good clean, renewable sources of energy. Let’s do that…. and get rid of old models, and let’s try to do what is right for community, for our economy, and for public interest.

Here’s the video:

Why solar cuts it better than any other energy source

Solar power is the fastest growing industry in the world, and south Georgia is an excellent place for it to grow and produce jobs, with plenty of rooftops and parking lots for solar panels.

This is despite the misinformation people with vested interests in other energy sources put out about solar power. After Dr. Matthew Richard made some points about solar vs. biomass, one of the members of the 6 December 2010 panel that VLCIA spent more than $17,000 to assemble to defend biomass responded that he was in favor of the nearby 300kWatt solar plant, but: well, I’m going to interleave his buts with what he’s ignoring.

Big oil tax subsidies: $9 billion / year —API

After last night’s Valdosta City Council meeting, someone told me he thought all renewable energy sources required subsidies, and that was the problem. Well, I think the real problem is the much larger subsidies to big oil.

Dan Froomkin wrote in huffpo How The Oil Lobby Greases Washington’s Wheels:

Despite astronomical profits during what have been lean years for most everyone else, the oil and gas industry continues to benefit from massive, multi-billion dollar taxpayer subsidies. Opinion polling shows the American public overwhelmingly wants those subsidies eliminated.
That’s at least $4 billion a year to big oil while Congress debates cutting Social Security and Medicare and maybe shutting down the government. According to the American Petroleum Institute (API), Continue reading →

“I’d put my money on the sun and solar energy.” –Thomas Alva Edison

Sometimes he was a prophet:
“We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature’s inexhaustible sources of energy — sun, wind and tide. … I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.”

— Thomas Alva Edison talking to Henry Ford and Harvey Firestone in 1931

Nuclear (Stewart Brand) vs. renewable energy (Mark Z. Jacobson) at TED

Stewart Brand of Whole Earth Catalog fame is a long-time environmentalist who in recent years decided nuclear was necessary. (He also decided no-till was necessary, which was enough to convince me he’s gone barmy.) Here at TED he debates Mark Z. Jacobson, whose new study says we can power the world with wind, water, and sun. I think Jacobson should reconsider including building more hydroelectric dams, but his study does demonstrate that we don’t need nuclear or biomass. But watch it and see what you think:

Here is my critique of Brand’s arguments: Continue reading →

Solar and wind: All that is lacking is the political will

Mike Childs wrote in the Guardian on 27 March 2011, Our green energy potential is huge, but gets little support: The crisis at Fukushima calls into question our nuclear power policy
Nuclear power is a gamble we don’t need to take. Studies show that the UK can meet its energy needs and tackle climate change without resorting to nuclear power or burning fossil fuels – all that is lacking is the political will.
Studies like this one for Scotland and this one for the whole world.

And the U.K. is way north of Georgia. Georgia gets a lot more sunlight and has plenty of wind off the coast. All that is lacking here, too, is the political will.

If Atlanta won’t lead, why not Valdosta and Lowndes County?

Scotland planning more offshore wind power than needed for all its homes

Aaron Colter wrote 23 March 2011: 5 GW Of Offshore Scottish Wind Power By 2020?
The Scottish Government has released a plan for offshore wind that highlights six areas for potential development. The original plan had selected ten regions for offshore renewable energy, however, four were ultimately abandoned due to predicted negative environmental and economic impact.

The six sites still in the running have an estimated energy potential of nearly five gigawatts by 2020, or enough to power 3 million homes. Richard Lochhead, Rural Affairs and Environment Secretary, said that Scotland’s commitment to offshore wind production could generate over $11 billion for the country’s economy and support up to 28,000 jobs over the next ten years.

For comparison, Scotland has about 370,000 households. According to the General Record Office for Scotland, Estimates of Households and Dwellings in Scotland, 2009:
In mid-2009, there were 2.34 million households in Scotland
That’s right, they’re talking eight 1.28 times as much power as all of Scotland’s homes could use. I would guess this means they plan to export some of that power, perhaps to England.

It seems renewable energy planning has spread beyond the Highlands to the rest of Scotland.

How to power the world with Wind, Water, and Sun

…a new study just published in the journal Energy Policy states that the world can provide for all of its energy needs, including electric power, transportation, heating/cooling, etc using only wind, water, and solar (WWS) energy by the year 2030.
By water the study authors, Mark Z. Jacobson (pictured) Mark A. Delucch, mostly mean hydroelectric power, which would involve building more dams, with all their environmental problems. Still, it’s an interesting study demonstrating that true renewable energy could power the world: no coal, no oil, no nuclear.

Current costs of major power sources

According to the U.S. Department of Energy, here are the current costs of coal, natural gas, nuclear, wind (onshore and offshore), solar (electrical and hot water), geothermal, biomass, and hydroelectric:

Here’s a four page explanation of that table.

Coal is not the cheapest: natural gas is. Onshore wind actually costs about the same as coal, and less than nuclear. Offshore wind is currently about 2.5 times more expensive.

Solar photovoltaic (PV) currently costs a bit more than twice as much as coal, and already less than offshore wind.

The table does not take into account the environmental costs of the various power sources, or obviously coal would fare far worse, and biomass would not be rated anywhere near as good as wind.

Remember, the cost of solar is falling rapidly, so solar will rapidly become more cost-effective compared to other energy sources.
