i thought we were talking about businesses, not individuals? I dont think he means using merely optional measures.

this is a good post, ty for teaching me something

"The Crescent Dunes CSP plant cost just under $1 billion, or $10,000 per KW, which is approximately 10 times the cost of an NGCC plant at $1,100 per KW."

Lol Solar, how many billions you guys want to waste?

Not that I'm just accepting whatever that blog says as fact, but cost per kw is not the correct way to compare. Life-cycle cost per kwh is and utility scale solar is delivering at under 3 cents per kwh and still going down fast.

Cost per kw doesn't even account for the cost of fuel during operation.

Also, whatever that project is sucks if that's true. Utility scale solar is routinely built for about $2000 per KW and I expect there are already projects as low as $1700/ KW.

So less than a month ago I posted a record low bid for utility solar at $0.0242/kwh and there's a bid in for the same project at $0.023/kwh. Also, a bid for a 500MW project in China for $0.46/W which is insanely low.

This is from that wordpress blog:

At this rate, solar plus storage and located in regions that aren't even that sunny will be reaching parity soon if it hasn't already. In sunny areas and not including storage solar is crushing and it will continue to be installed as quickly as solar modules can be manufactured.

I'm happy about this for the sake of humanity, but Shifty, I think you'll understand that this makes solar a challenging business. It's not easy to be part of an industry where prices are rapidly falling. Yeah, it's mostly material prices and I'm not a module manufacturer, but competition for price is very intense.

note: Bids per kwh are selling energy and that would be for a contract over time, usually 20 years. Bids per watt is based on the power rating of the system and is the equipment and construction, but turned over to the client. They just get the energy from that point on rather than paying for it.

Hey guys, this random Wordpress site said solar is bad, which I already want to believe is true so let me suspend my critical thinking for now and just celebrate that I found a source which agrees with my preconceived notions!

Go go Tesla! Super excited about this if I someday happen to be a home owner.

It's a cool but not original idea. I built a waterproof roof with solar modules like 6 years ago. The modules were semi-transparent - so like a big skylight.

There have been lots of solar shingles and tiles over the years and none really sold.

The battery (powerwall) isn't really original either, but it could have a big impact because what is really the big story is the gigafactory will hopefully bring prices for large lithium based batteries way down.

Just saw an ad

FLORIDA'S FIREFIGHTERS SUPPORT AMENDMENT 1!

Like why in the actual **** would "Florida's firefighters" give a squirt of piss about that?

The first thing the FD wants to do when they come to fight a fire at your house is turn off your power. The solar panels are on whenever the sun is shining. Another thing the FD likes to do is climb on your roof and cut holes in various places without getting electrocuted.

It took a while for everything to be cool with the FDs in California, but It's all working smoothly at this point.

FD's first reaction is basically "are those things going to kill me? "

Well when/if you see the ad, note the acute lack of concern on the part of our hero for any of those dangers you cited

Dunno why else they would especially care. I wouldn't be surprised if firefighters skew conservative though.

Otoh, firefighters and cops are good customers. I've installed on bunch of their homes.

Colonial pipeline, same pipeline company as had the big spill about a month ago, had a pipeline explosion in Alabama. Killed one person so far.

In other fossil fuel news, 33 coal miners killed in an explosion yesterday in China.

is this actually unsafe? when i looked a couple of months ago, most connected solar inverters will shut themselves off if they detect no current coming from the grid. i.e. firefighters should still be able to shut off the power. is this incorrect?

As far as I know, no firefighter in America has been killed by a solar array and there's a fair chance I'd hear about it as the few times an installer has died (from falling of the roof or ladder every time I've heard of) it seems like word gets around.

In California (and probably elsewhere too) there are guidelines from the State Fire Marshall designed to protect firefighters and allow them to fight a fire on a structure with solar. The rules include pathways for the firefighters, clear space at the ridge so that the roof can be vented, labeling and rules about the conductors in attics to keep them away from chain saws.

Ok, now to get to your question.

The inverters automatically shut down on a grid connected system because otherwise when the power were out the system could continue to supply energy to the utility lines, which could shock unsuspecting utility personnel working on the lines.

The solar modules (panels) don't turn off when the inverter turns off. If you have a system with a central inverter and solar modules strung together you can have voltages on residential systems up to 600 volts. With the inverter off that's just voltage - potential - there's nowhere for the current to go. But, if your body became part of a circuit because you put your axe into a conductor while another part of your body were grounded, you could get shocked.

(a few things left out to avoid complication - there are ungrounded systems - microinverters or power conditioners change the answer)

One of the most anxious nights I've ever spent came after someone told me there was a fire at a winery where I had recently installed solar and that's all they knew. But, thankfully, no one was hurt, the damage wasn't too severe and the cause had nothing to do with the solar. A natural gas forklift inside caught fire.

As temperatures go into the 20s at Standing Rock they are spraying the protestors with water canons and hit one woman with a concussion grenade and she might end up having to have her arm amputated.

There have been 3300+ pipeline spills since 2010. The Dakota Pipeline was originally planned to go near Bismarck, but the Gov't decided:

But, the reservation is a perfectly acceptable place to risk a spill. (Not that a spill will necessarily stay on the reservation if it gets into the Missouri River.)

3300+ spills. How many were contained? Cleaned up safel.? If your against pipelines do you have a safer way to transport light crude?

Yes, through Bismarck or not at all. Sunoco just acquired ETP and has the worst record of spills since 2010. You don't see these spills on the news unless you are local where they happen, for "some" reason they don't make national headlines. I'd much rather have trains and trucks than half a million barrels a day flowing under the Missouri River at the source of drinking water for one of the larger (and beautiful) reservations in the nation.

Do conservatives purposely refuse the learn the proper use of your and you're - or does it just come naturally?

But yeah - you're much smarter and wiser than those over-educated ivory tower egghead libtards who can't figure out earth big/humans small or stuff like melting ice in water won't raise sea levels. Dumb dumb scientists. So dumb.

Yup you caught me, I had no idea there was a difference. Or It was 5am and I was at an airport and didn't care about proper grammar while posting in the politics section of a poker forum.

High consequence areas are determined by population density. Many, many go through high consequence areas, but they have different regulations that they have to follow. For example the pipe depth is required to be deeper to prevent third party excavation damage, which is by far the number one cause of leaks.

A modern pipeline installed more than 50ft below the river bottom has a miniscule chance of contaminating the water. Forcing these companies to transport product through older shallower pipelines is much more risky since the existing lines are most likely dredged in or simply weighted down across river bottoms. This increases the chances of third party damage dramatically.

I want to obstruct new fossil fuel projects because that speeds up the transition to renewables and means more fossil fuel will ultimately be left in the ground.

Surprised this has not been posted.
