Japan Will Need To Dispose of 110,000 Solar Panels per Day!

A mess of panels.

TOKYO —  Solar panels have sprung up across Japan in the past few years, after the government introduced a “feed-in tariff” in July 2012 that guarantees prices for electricity generated from renewable energy. When these panels reach the end of their working lives in 20-30 years, they will create a mountain of waste.

 

By 2020, Japan’s Environment Ministry forecasts the country’s solar-panel waste will exceed 10,000 tons.

After that, the pile really starts growing: reaching 100,000 tons in 2031 and topping 300,000 tons in 2033, the 20th anniversary of the feed-in tariff.

Between 2034 and 2040 the amount of waste produced is expected to hover around 700,000-800,000 tons annually.

The projected peak of 810,000 tons is equivalent to 40.5 million panels.

To dispose of that amount in a year would mean getting rid of 110,000 panels per day.

10 Hours of Sun in Germany for December 2017

Tags: , , , ,

At NoTricksZone the insanity of Germany’s “plan” for saving the worlds from cheap electrcity is on display.

80GW of demand (the reddish line)

40 GW of installed solar producing almost nothing (the yellow)/

10 hours of sunshine in Germany for the whole month of December.

 

 

As Jo Nova says:

“Imagine what kind of havoc this kind of energy flux can do. Not one piece of baseload capital equipment can be retired, despite the fact that half of it is randomly unprofitable depending on cloud cover. Solar PV eats away the low cost competitive advantage. Capital sits there unused, spinning on standby, while wages, interest, and other costs keep accruing. So hapless baseload suppliers charge more for the hours that they do run, making electricity more expensive.

They just need batteries with three months supply.”

Solar Array UHI = PVHI = 3C to 4C

Do you have a lot of solar cells in your neighborhood or city or state? Then welcome to the PVHI.

“Because there are still large uncertainties surrounding the potential for a PHVI effect, we examined the PVHI empirically with experiments that spanned three biomes. We found temperatures over a PV plant were regularly 3–4 °C warmer than wildlands at night, which is in direct contrast to other studies based on models that suggested that PV systems should decrease ambient temperatures.”

And then your region can buy more air conditioners to try and cool off the evening, which will then pump more warm moist air into the area, which will increase the night time temperatures even more and then ….

Streamers

The wisps of smoke are birds/insects being immolated by the Ivanpah solar farm.

la-me-solar-bird-deaths-pictures-009

A macabre fireworks show unfolds each day along I-15 west of Las Vegas, as birds fly into concentrated beams of sunlight and are instantly incinerated, leaving wisps of white smoke against the blue desert sky.

Workers at the Ivanpah Solar Plant have a name for the spectacle: “Streamers.”

Federal biologists say about 6,000 birds die from collisions or immolation annually while chasing flying insects around the facility’s three 40-story towers, which catch sunlight from five square miles of garage-door-size mirrors to drive the plant’s power-producing turbines.

Coyotes are getting fat on Roadrunners.

In addition, coyotes eat dozens of road runners trapped  along the outside of a perimeter fence that was designed to prevent federally threatened desert tortoises from wandering onto the property.

The World’s Largest Solar Plant Just Torched Itself

Ouch.

Misaligned mirrors are being blamed for a fire that broke out yesterday at the world’s largest solar power plant, leaving the high-tech facility crippled for the time being. It sounds like the plant’s workers suffered through a real hellscape, too.

A small fire was reported yesterday morning at the Ivanpah Solar Electric Generating System (ISEGS) in California, forcing a temporary shutdown of the facility. It’s now running at a third of its capacity (a second tower is down due to scheduled maintenance), and it’s not immediately clear when the damaged tower will restart. It’s also unclear how the incident will impact California’s electricity supply.

Putting out the blaze was not easy task, either. Firefighters were forced to climb 300 feet up a boiler tower to get to the scene. Officials said the fire was located about two-thirds up the tower. Workers at the plant actually managed to subdue the flames by the time firefighters reached the spot, and it was officially extinguished about 20 minutes after it started.

Phrase of the Day: Duck Curve

Filed under: solar — sunshinehours1 @ 11:07 AM
Tags: ,

The problem with solar power on a state wide basis is that it peaks at mid day while “everyone” is at work and no one is doing laundry or cooking dinner or turning on the A/C at the end of a long hot day at work or school.

There is a real risk of overgeneration which means you need to dump electricity somewhere or quickly shutdown any non-solar power you can.

And then kids start coming home from school and then the sun starts to go down and the parents come home and put something in the oven and maybe do a load of laundry and plug in the hybrid car.

And suddenly you need 13,000MW of power to pump into the grid.

And the demand curve looks like a duck.

The surge in intermittent solar power will test the statewide electricity grid because it exacerbates the need for alternative sources such as gas outside of daylight hours. Regulators have warned it’ll make California more vulnerable to price spikes and power disruptions.

German Electricity Week 14 2016

Filed under: Germany,solar,wind turbines — sunshinehours1 @ 9:57 AM

Germany is planning to rely on wind and solar. Last week on April 8th, wind and solar combined for 0.94GW out of 55GW.

Averages don’t keep the electricity on. They will need lots more brown coal when they shut down the nuclear power stations.

Germany_Week_14_2016

The whole week (just solar and wind). Yes, sometimes combined they generate a lot of electricity.

But on April 8th Germany went almost a 1.5 days where almost nothing was generated by wind.

Word of the Day: Dunkelflaute

Word of the day:

In German, the term Dunkelflaute is used to describe the predicament. Dunkel means “dark”; solar is simply not available half the time, and solar power production is significant for only around six hours a day even when the sun is shining. Flaute is “doldrums” – when the wind is not blowing. So the “dark doldrums” are times when solar and wind power is not available in sufficient amounts.

This chart is just wind+solar for March in Germany. Red lines are periods less than 5GW.

Oooops. Germany Forgot About Eclipses

Oooops. Germany Forgot About Eclipses and their effect on a power grid with lots of expensive solar.

The German power grid operators are dreading March 20, 2015. On this day Germany will see a partial solar eclipse during the morning. Should there be no clouds in the sky at this time, all solar power generating systems all over the country would be feeding in drastically less power into the grid in just a matter of minutes – and the grids would become dangerously destabilized.”

Conservation group sues to stop California solar plant

It’s only fair …

“LOS ANGELES – A U.S. conversation group has sued the federal government over its approval of a major solar power plant in the California desert, the latest in a string of challenges to the nation’s renewable energy goals from the environmental community.

According to court papers, the non-profit Western Watersheds Project alleged U.S. regulators approved Brightsource Energy’s 370-megawatt Ivanpah solar energy plant without conducting adequate environmental reviews, and asked the court to order the defendants to withdraw their approvals.”

“”In an ill-conceived rush to accommodate massive renewable energy projects … the federal defendants precipitously approved unnecessarily destructive energy development of the California Desert Conservation Area without first conducting adequate environmental reviews.The complaint said the project’s approval process failed to analyze and mitigate the Ivanpah plant’s impact on migratory birds, the desert tortoise, which is a threatened species under federal law, desert bighorn sheep, groundwater resources and rare plants.“”
