Friday Linkage 2/24/2017

November 9th was a day of some serious despair, but I see a lot of potential in the awakening of a progressive spirit and an exposure of the right wing’s anti-people agenda.  Yes, it will be a lot of work to make any kind of meaningful change given the dynamics of elections in the U.S.  Yes, Donald Trump is a dumpster fire in human form that happens to inhabit the Oval Office.  However, there has been a spark that has ignited a liberal fire like no other time in recent memory.

On to the links…

U.S. Greenhouse Gas Emissions Lowest Since 1994—A lot of this decline has to do with the replacement of coal with natural gas in the electrical generation sector and a recession that dampened demand across a whole host of industries.  Nonetheless, the data is compelling:

The Future of Solar Power Technology is Bright—No matter what the political environment looks like in the future, the potential of solar is very real.

Record Wind & Solar Keep The Lights On In NSW As Coal & Gas Went Missing—Renewable energy can make the grid more reliable.  This should put the argument about intermittency to bed.

Wind Technician Jobs Growing, in Iowa and Nationally—The sooner that everyone realizes that there are more people working in renewable energy jobs, like wind turbine technicians, the sooner that we can get past the narrative of coal jobs being the only energy jobs that matter.

Drilling Experts Explain why Trump Can’t Bring Back Oilfield Jobs—The jobs will not be coming back because like coal before it automation and market changes are driving the need for actual human labor down.

University of Iowa Announces it will be Coal-Free by 2025—Each power generating facility or consumer that goes coal-free is another brick in the wall in eliminating coal from our energy infrastructure.  Yes, it will take a long time.  Yes, it is inevitable if we keep up the pressure.

Petcoke Piles Gone, but Another Dangerous Pollutant Discovered in the Air—If you think that there is no place for the EPA it is likely that you do not live in a community affected by this kind of pollution.  Low income communities are at the mercy of polluters because they do not have the political clout of the Koch brothers.

Which Ski Run Is Better for the Planet?—Ski hills go out of business.  What comes after is hard to imagine as you spend your days sliding.  However, the way we develop ski runs can make a major difference for the next stage of the land’s lifecycle.

Almost Every Packaged Food Comes from These Two Companies—The merger between Kraft Heinz and Unilever may have died, but this should give you some sense as to how consolidated the center aisles of the grocery store have become.

Olive Oil Shortage Looms as Prices and Demand Rise—Climate change has come for our coffee, chocolate, and hops.  Now olive oil is the crosshairs.  When will the larger populace realize that the impacts of climate change is here.

Fifth of World’s Food Lost to Over-Eating and Waste—Food insecurity is not a question of production it is a question of distribution, availability, and affordability.  It is a god damned shame that we live in a world where a significant portion of the world’s population is overweight while a similarly large portion of the world’s population is food insecure.

The Tesla Model X came out this week and I want one. But, at a starting price of $80K I might be better off looking at used Nissan Leafs costing under $10K. When will the Model 3 come out?

Note, there will be no Friday Linkage next week since I will be spending the week in Los Angeles evaluating suppliers for my job.

Coal Mine Starts Continue To Decline—This is the second step on the journey to the death of coal. If fewer mines are opening than fewer mines will be operating further eroding the ability of the fuel to be effectively and efficiently pulled from the ground. Let’s kick coal while it is down.

Is Cargill Backsliding on its Promise to End Deforestation?—Few large corporations are as hard to pin down on issues than Cargill. As a privately-held firm it is not beholden to the same reporting rules that allow shareholders to extract information from publicly-held firms. Perhaps public pressure can take some of the slack and get Cargill to be a good corporate citizen. I am not holding my breath.

Nearly Half of U.S. Seafood Is Wasted Annually, New Study Shows—Food waste is the single biggest environmental issue that we have control of in our own homes and through our consumption patterns. Every piece of food that we throw away is a wasted opportunity to reduce our impact on the world.

Batteries May Curb Sales by Power Companies, Moody’s Says—If the large scale deployment of energy storage technology is truly able to reduce peak demand power companies may lose a major source of profit. Power becomes very expensive and profitable for power companies when it comes at peak times.

Solar Hit ~7% Of Spain’s Electricity This Summer—Damn, 7% from solar is impressive any way you slice it.

Brazil Doubles Its Solar PV Target To 7 GW By 2024—What is the target in the good ol’ U.S.A.? Right, we do not have a national target for solar.

North Carolina Passes 1 GW Of Installed Solar—That seems like a lot of solar for one state that is not known as a particularly sunny locale.

Fracking has a Big Water Footprint, but That’s Not the Whole Story—The extraction of fossil fuels is a story about water. Without a lot of water it would not be possible.

Electric Buses Could Lead to Significant Savings Even for Smaller Cities—Why the government is not pushing electric buses and garbage trucks I will never understand. These vehicles seem like perfect candidates for conversion.

Saving Electricity—Spend a few minutes going through the various categories to see where you could be saving a lot of watts. Since I cannot get solar panels in the near term—thanks homeowner’s insurance—I am going to try and reduce my rolling twelve month usage below 300 kWh.

‘Thirsty’ Concrete Absorbs 880 Gallons of Water a Minute to Minimize Urban Floods—Why is this stuff not replacing hard concrete and asphalt in southern climes affected by heavy seasonal rains?

The rides the past couple of weeks have been perfect. Just perfect. The temps are in the 70s to low 80s, the winds have not been too bad, and the crowds are gone. Especially on Saturdays when people are busy tailgating and watching college football, I have the trails and gravel all to myself. Unheard of in July.

Ban on Microbeads Offers Best Chance to Protect Oceans, Aquatic Species—The U.S. needs to enact a nationwide ban on plastic microbeads. Exfoliation is not worth the health of the oceans.

How Strict California Rules on Emissions led to Lower Cancer Risk—Regulation works. Plain and simple. Without emissions reductions California would still be blanketed in a horrible stew of smog and death.

Taxpayers Lose Billions to Coal Subsidies—Stories like this cannot get enough press. As taxpayers we pay billions to coal companies in order for them foul our air, dirty the water, and generally behave badly.

Balls of DNA Could Fix Geothermal Energy’s Biggest Problem—Geothermal is a great renewable energy resource because it is dependable enough to be considered “base load” like coal, natural gas, or nuclear. Unlike hydropower, the other base load renewable, large dams are not required and drought will not impact production. It looks like one of the thorniest problems may now be solved as well.

Obama Sets Up Cost Of US Solar Energy For Another Freefall—Fundamental research is being paid for that will drive down the entire system cost for solar. Remember when solar panels were only something you saw in Mother Earth News or on the lot of some burnt out hippie? Yeah, it’s mainstream now and will be more so in a few years.

Beyond Sprawl: A New Vision of The Solar Suburbs of the Future—We have a lot of development tied up in suburbs. This infrastructure is not going to go away and be replaced by dense, urban communities. How can we reform the suburb to make sense in a new era?

Tesla Gigafactory & Battery Improvements Could Cut Battery Costs 50%–A reduction of this magnitude would make some serious waves.

UK To Remain Offshore Wind Giant With Forecasted 23.2 GW By 2025, GlobalData—I keep wondering when offshore wind is going to explode. Maybe that time is now.

China’s Wind Energy Capacity To Triple By 2020, Says GlobalData—For all of the bad things China does—pollution out of control, corruption, political repression—they sure are going after this whole renewable energy thing with gusto.

Your Body Immediately After Drinking a Pumpkin Spice Latte—It’s that time of year when the pumpkin spice comes out and everyone wearing Ugg boots seems to have one in their hands. Here is what that concoction from satan’s belly does to your body.

I Ate a Bunch of Vegan Cheese, and It Was Actually Quite Tasty—As someone who has a child who is lactose intolerant and loves cheese all of these products are going to be on my next shopping list.

If You Never Knew You Needed It, Don’t Buy It—This is a rule we all should live by when shopping. How do you think Costco works? How many times have you ended up with something that was not on your list because it seemed so cool and useful?

Imagine a World without Waste: It’s Possible with a Circular Economy—Would this even fly in the west anymore? The minute someone would talk about these concepts in a political space the cries of “socialist!” and “communist!” would ring out.

Winter is coming. At least that is what my daughter thinks now that the air conditioning is off for the summer and the night time temperature is dropping into the 40s. She is constantly asking how many days it is until ski resorts in Colorado open. We might have created a monster here.

On to the links…

US Solar Capacity Now Exceeds 20 GW—Believe it. I am hoping to add my own little bit to this number before the close of the year with an approximately 5 kWh system on a west facing roof. Permits be damned.

Why Solar PV is Unstoppable – and Renewable Targets will Cost Little—Fossil fuels are looking over their shoulder at the ultimate killer app in solar. Once deployed it is cheap because the fuel is free and the lifespan is long because the technology is solid state.

The Default Move For US Oil Is Downward. Here’s Why—An interesting technical analysis of the recent drop in oil prices and why we may be looking at a new normal. I think this price drop is a temporary reprieve that gives our economy some breathing room to start making a real transition away from fossil fuels.

Kauai Utility Signs Deal with SolarCity on Energy System to Provide Power at Night—Hawaii has mad renewable energy potential, but the problem is that peak demand continues after the period of peak production crests. This pilot project aims to level out some of that disparity and pump clean power back into the grid after the sun goes down.

Colorado Invests $1.2M In Low-Income Community Solar Projects—One of the biggest and most poignant critiques of solar is that it is something reserved for people with a large degree of discretionary income. Community solar that is subsidized by some degree may be an answer to this critique.

India’s Installed Solar Power Capacity Tops 4 GW—I am kind of a solar junkie when it comes to news stories. I love hearing/reading about new milestones.

Delhi Eyes 2 GW Rooftop Solar Power Capacity By 2022—Remember, this is rooftop solar so it is going on top of existing buildings instead of taking up ground in greenfield or brownfield sites. What is the potential across the world for such an endeavor.

India’s Wind Energy Potential Upgraded To 302 GW—The interesting thing about this number is that slightly more than half is available in what is considered waste land.

How Australia’s Electricity Demand Is Slashed By Solar PV—Simply put when solar panels are producing the most power is when there is a spike in demand. Point of use solar power generation is knocking down the peak of demand.

From Icky Bugs to Good Grub: Why More People are Eating Insects—I think that I read one or two of these stories each year that claims the boom in eating insects is a year or so away. It feels a lot like nuclear fusion. It’s a ten years away and that was true ten years ago.

In Praise of Cheap Knives—I am always reminded of a woodworker I knew who collected beautiful tools in a manicured shop, but no one could ever recall him actually building anything.

Damn, I looked up and it was September. Without cable and no more HDTV football season will not be the same. Listening to games on the radio, however, gives me the opportunity to spend some time in the shop working on a handful of projects that have languished most of the summer.

On to the links…

MidAmerican Energy Announces New Wind Farms—By the end of 2015, MidAmerican will get 42 percent of its power from wind versus 36 percent from coal. That is an impressive renewable energy footprint that is only going to get bigger with the construction of these recently announced projects.

Simple Solar From Cedar Falls Utilities — Crowdfunded Community Solar—Iowa has a long way to go with regard to climate change mitigation, but there are a lot of good things happening on the ground. Cedar Falls, famous for its public internet company, is also getting into the community solar game.

Xcel Energy Taking Heat for Slow Rollout of Solar Garden Program in Minnesota—Meanwhile, Xcel in Minnesota seems to be doing everything to kill the community solar project with a thousand cuts.

Hawaii’s Going 100 Percent Renewable, And It’s Not Using Natural Gas As A ‘Transition’—Hawaii is going to try and make the leap to all renewables without taking the baby step of using natural gas as a bridge fuel. I wish them the best of luck because the islands can be a laboratory for the rest of the United States.

Florida Public Service Commission OKs FPL’s Plan To Purchase & Shut Down 250 MW Coal Plant, As Means Of Getting Out Of Costly PPA—This is how you know coal is troubled. It is easier for a power company to buy and shut down a plant as a means of avoiding contractual power purchase obligations than to go ahead with the contract.

Digging into Big Coal’s Climate Connections—The great thing about bankruptcy of a public company in the U.S. is the enormous amount of information that becomes public as a result. Alpha Natural Resource’s bankruptcy is pulling the curtain back on climate shenanigans.

Unicornomics—If you want to understand right wing thinking in the 21st century you need to understand that it is based on the belief that reality and facts are secondary to dogma. I want a unicorn farm, but that does not mean I am going to get a unicorn farm.

Farmed Fish could bring Us Cheaper Food, but is it Ethical?—Aquaculture is the future of the fish on our tables because we have trashed and overfished the oceans. There are a lot of problems with aquaculture, but we can try to work through those for a better system.

9 of 10 Seabirds Have Glow Sticks, Lighters, Toy Cars, Other Plastics in their Guts—We have trashed the planet, the animals are paying the price, and we have to figure out a way to start cleaning up after ourselves.

Climate Change Means One World’s Death and Another’s Birth—The world is going to change. It might change at a pace that is understandable on the human being’s lifespan. This is unprecedented.

The True Story of Kudzu, the Vine That Never Truly Ate the South—This story kind of bummed me out because kudzu was the plant from a horror movie in my youth. It was the cautionary tale that every biology teacher used to illustrate the folly of trying to mess with nature.

It got unseasonably cool here in eastern Iowa this week. Like, mid-50s at night and no more than mid-70s during the day. I am sure that we will pay for this comfortable weather with a slap of hot and humid in the coming weeks, but it was a nice preview of the cool fall weather to come.

How The EPA Plans To Cut Methane Emissions From Oil And Gas Wells—This falls into the “boring, but important” category of news. The EPA is proposing new regulations on methane emissions, which is important because methane is a very potent greenhouse gas and a lot of methane is released at gas drilling sites.

Four Powerhouse Bills to Help California get to 50 Percent Renewable Energy—In a lot of economic and policy circles the saying goes “As goes California…” because the size of California determines a lot of what happens in the rest of the country. If California could really get to 50% renewable energy it would be a major change.

World Needs 53GW Of Solar PV Installed Per Year To Address Climate Change—If that is the number, how do we get to 53 GW per year? I know that this is more of a thought exercise than anything else, but in order to beat the worst of climate change we are going to need addressable goals.

Coal Mining Sector Running Out of Time, says Citigroup—I am not going to start playing the funeral dirge just yet, but when major financiers and banks are pulling out of coal and being public about the shift the winds of change are blowing.

90 Years of U.S. Fuel Economy Data Shows the Power of Incentives, Dangers of Stagnation—This is a pretty compelling chart:

Why did we have such a lull in the 90s and early-2000s? Oh right, SUVs and a right wing that encouraged nothing but “drill, baby drill.” Thanks.

How Much Of California’s Drought Was Caused By Climate Change? Scientists Now Have The Answer.—California is bound to go through periodic droughts, but it looks like the current drought cycle is being exacerbated by climate change.

How Killing Elephants Finances Terror in Africa—This is just a fascinating read. The author placed GPS chips into fake elephant tusks to track where illicit ivory made its way across the globe.

The Pork Industry is Full of this Drug You’ve Never Heard Of—Ractopamine, besides sounding like the name of a plague in a spy movie, is bad stuff. Most of the rest of the world has not deemed meat raised with this drug safe for human consumption, but in the good ol’ USA it’s what’s for dinner.

How the Midwest’s Corn Farms Are Cooking the Planet—Industrial corn production is turning out to be one of the more environmentally damaging agricultural pursuits of the modern age. Maybe it is time we start looking at a different paradigm.

The American Lawn Is Now The Largest Single ‘Crop’ In The U.S.—If corn is bad, lawns are downright insane. At least there is something that comes out of a corn field. A lawn is just a green carpet that requires more maintenance than wall-to-wall white shag carpeting.
