Analysis: Renewable “gold rush” powers Germany’s north shore

 

 

By Erik Kirschbaum

ROSTOCK, Germany | Mon Oct 17, 2011 6:04am BST

(Reuters) – Renewable energy has created a “gold rush” atmosphere in Germany’s depressed north-east, giving the country’s poorhouse good jobs and great promise.

The natural resources attracting investors and industry are of a simple variety: wind, sunshine, agricultural products and farm waste such as liquid manure.

The rush to tap green resources in Mecklenburg-Vorpommern state is reminiscent of the frenzies that came with gold or oil discoveries in past centuries. The buzz can be felt in towns and sparkling new factories across the Baltic shore state.

“Renewable energy has become extremely valuable for our state,” said its premier, Erwin Selling, in an interview with Reuters. “It’s just a great opportunity — producing renewable energy and creating manufacturing jobs.

“From an industrial point of view we’d been one of Germany’s weaker areas. But the country is abandoning nuclear power. That will work only if there’s a corresponding — and substantial — increase in renewables. It’ll be one of Germany’s most important sectors in the future. We want to be up there leading the way.”

Taiwan Does Solar In A Big Way – Asia in general understands the need to ditch coal

China is having smog days in some cities that have pollutants 50 times higher then allowed in the United States. Rates that can cause lung damage in mere minutes. So everyone in Asia is well aware that they need to switch from carbon fuels to renewables. Unfortunately, India has not learned the lesson yet.  But Taiwan definitely has.

The rise and rise of Taiwan Solar

21 Oct, 2013

(I skipped the first couple of paragraphs)

Either way, this beautiful, mountainous, island nation has become a technological powerhouse in Asia. Driven initially by Japanese influences prior to World War 2, it has developed a highly successful semiconductor industry including wafer foundries, Integrated Circuit (IC) packaging and testing industries and was considered the world’s number one in 2011 in terms of IC revenues.

The Taiwanese semiconductor industry developed an early vertical integration model (upstream, midstream, and downstream sectors) including silicon materials and silicon wafering; midstream IC design, IC manufacturing, and IC packaging industries; and downstream computer, cellular phone, and consumable electrical product companies. The transition from semiconductor to photovoltaic industries was a therefore a logical and natural progression for Taiwan and explains why it has become so enormously important.

Fast forward to 2012 and the beginning of trade tariffs on Chinese made PV products in some countries.  With deep historical and business ties to China but technically an independent status, the importance of Taiwan’s PV manufacturing sector took a huge leap forward.

One example of the Taiwanese PV industries rise to PV success is WINAICO.  WINAICO’s parent company is Win Win Precise Material Co Ltd who established themselves in 2003 as a supplier and marketer to the semi-conductor industry. By 2007, it had created Winergy Solar and soon afterwards WINAICO, establishing a network of global sales offices and joint ventures to develop, market and deploy its PV technologies.

The OIL Drum goes offline – Does that mean that Peak Oil Theory is wrong?

That is a very interesting question. At one level is is just a case of a bad attribution. It would be like saying if Jane’s stopped publication then there are no airplanes. At another level, as all the authors say that were involved, they may have just run out of new and bright things to say. It could also be that with many other things predicting the END OF THE WORLD, when it never happens, the readers got bored. That several major religions have preached that for thousands of years and nobody has gotten bored yet would speak against that. I have always been skeptical about the doom and gloom nature of the blog itself but when the CIA and the Defense Department believe something then, you have to believe it has some credibility and really oil is a finite resource. So with deep water drilling and fracking we may just be buying time. Then there is global warming. Anyway I drivel on.

Our Clean Energy Future

Posted by Big Gav

Following on my recent post bidding Farewell to The Oil Drum, I’d like to have a look at what I view as our longer term future for energy production and consumption.

As noted in my previous post, for the time being the combination of unconventional oil extraction and the ramping up of extraction of natural gas (from both conventional and unconventional sources) has continued to push the point of peak oil production out into the future, defying the predictions of the more pessimistic peak oil observers. During this period we have seen a boom in the research and development of solutions to help us eliminate our dependency on fossil fuels, which I’ll explore in this post.

Solutions can be divided into 3 groups :

 

  • Renewable energy – solar power, wind power, geothermal power, hydro power, ocean energy and biomass derived power (including biofuels)
  • Distribution of renewable energy – energy storage and the electricity grid
  • Adopting alternatives to oil and other fossil fuels – electric transport, bioplastic, alternatives to fossil fuel based fertiliser and new models for manufacturing, construction and agriculture

 

Renewable Energy

The graphic below shows the energy available from renewable energy sources annually compared to global energy consumption. The numbers are intended to give a rough idea of relative scale – for any given energy source a wide range of estimates can be found in the literature so the numbers are indicative.

 

These numbers in some ways understate the amount of energy potentially available (ignoring solar power potential at sea or in space, for example, or wind power at high altitudes or far offshore, or geothermal power deep below the surface of the earth) but still serve the demonstrate that the renewable energy available to us is orders of magnitude larger than our current global energy consumption.

The contribution made by renewable energy to our energy needs is expected to exceed that made by gas (and double that made by nuclear power) by 2016, though progress needs to be accelerated if we wish to create a sustainable energy system.

Solar power

Solar power is the largest energy source available to us, dwarfing all other sources – renewable and non-renewable. Approximately 36,000 Terawatts of power could be captured by land based solar power generation – compared to current global energy use of around 16 TW. As a result, most of the plans floated for shifting to 100% renewable energy (examples include proposals by Mark Jacobson and Stuart Staniford and local plans for countries like Germany and Australia) rely primarily on solar power.

Solar power is not only the largest energy source available to us but it is also the fastest growing energy source, with solar power generation increasing by over 58% in 2012.

There are a number of options for harnessing solar power – power generation using solar photovoltaic (PV) cells and solar thermal arrays along with passive solar techniques such as solar hot water heaters.

I have been of the view that solar thermal power generation (also known as concentrating solar power or CSP) would become our most important source of power in the longer term. This view was based on a number of advantages that solar thermal possesses – it does not require rare or expensive materials (enabling it to scale without hitting resource limits), it can be built on (and is best suited to) arid land that has few other uses, it can incorporate energy storage (thus avoiding the intermittency issue), it is compatible with the existing centralised generation model and it can be combined with traditional sources of power generation (coal or gas) in hybrid power plants that allow an easy transition using existing connections to the electricity grid.

An area of desert around 250 km by 250 km covered with solar thermal power generation could supply all the world’s current electricity demand.

Fukushima – The ongoing threat

Posted on by

While it is true that this “underground river of water” or what ever it is, is troubling. It is also clear that the bloggers and the fear mongers also want to have an end of the world hissy fit. The truth probably lies in the middle somewhere, BUT the fact that this is 2 and 1/2 years later is both dangerous and unacceptable. I lay this one at the foot of the antiquated class structure of Japan and its notion that deference is the only honorable approach to major social conflicts. This is at its heart a cultural conflict between the business community and the government which the business community wants to win. Such a win could end us all and the fact that the Japanese government is just now catching on is frightening.

Official: Tepco Plan Could Cause Fukushima Reactor Buildings to “Topple”

Posted on August 7, 2013 by WashingtonsBlog

Japan’s Nuclear Accident Response Director Warns that Tepco’s Actions Might Cause Reactor Buildings to Collapse

Tepco’s ill-considered efforts to change soil permeability and water flow have caused severe problems at the site … including highly radioactive groundwater bubbling up to the surface.

NHK notes:

The vice governor of Fukushima Prefecture has asked the government to take the lead in handling the matter and stop the leakage. Masao Uchibori told an official from the Nuclear Regulation Authority that some of Tepco’s measures have increased the risk of further leaks.

The Wall Street Journal’s Michael Arnold says:

Obviously this is a massive public health issue … if it gets into the ocean obviously this could be spread throughout the Pacific, could also get into the food supply.

Background here and here.

But there is another – stunning – threat.

Specifically, BBC points out:

Engineers are now facing a new emergency. The Fukushima plant sits smack in the middle of an underground aquifer. Deep beneath the ground, the site is rapidly being overwhelmed by water.

What happens when you pour hundreds of thousands of tons of water (400 metric tons each day times 2.5 years times 365 days in a year equals 365,000 metric tons of water)  onto soil which sits above a massive aquifer?

Should SolarCity Change Its Name – Changing their name to EfficiencyCity

Posted on by

I mean really if they are going to drop their insistence on solar panel installations as part of a retrofit then why keep the name? Are they now a software company or are they now a software and then install whatever company? Good questions with no answers. It would be like Tide if it were to stop making soap and started making dishwashers. Would they keep the name and why?

http://www.greentechmedia.com/articles/read/a-peak-at-solarcitys-new-energy-efficiency-software?

Has SolarCity Created the Amazon 1-Click for Energy Efficiency?

 

“We believe SolarCity has the best database of residential energy use of anyone in the world.”

 

Stephen Lacey: June 28, 2013

 

After SolarCity shifted its energy efficiency strategy and pulled back from doing residential retrofits in-house, the solar services behemoth is moving straight into intelligent efficiency.

 

GTM’s Eric Wesoff recently reported on SolarCity’s evolving business plan and the resulting changes that company executives say will scale residential efficiency in the same way solar services have scaled residential solar.

 

But solar is very different from efficiency. For the most part, solar is very standardized and installations are uniform from home to home. Efficiency retrofits encompass an extraordinarily broad category of activities and skills. Incentives are also quite different for efficiency, making it more complicated from a financial perspective. That’s why only a handful of U.S. solar contractors have offered efficiency as an in-house service.

 

SolarCity decided that doing the retrofit work itself was not the best way to scale. Instead, it has turned from manpower to the power of big data.

 

The secret sauce is a “simulation engine” that shows homeowners exactly how much they’re spending on energy everywhere in their house. The initial database was created using information from 16,000 home energy audits performed over the last five years. It relies on an algorithm developed at the Department of Energy that crunches 100 million calculations per home for each individual energy efficiency audit (which is still performed by SolarCity when installing solar).

 

“The simulation software looks at every component in a home in relation to one another,” said SolarCity COO Peter Rive. “Every ten minutes, it thinks about what one thing is doing and about its effect on the rest of the systems within the home.”

Petersburg Is An Energy Producer – At the high school no less

Petersburg school nominated for solar energy program

Dan Petrella 06/18/2013 – 11:22 PM EDT

PETERSBURG — The PORTA School District could soon add more solar power to its alternative energy portfolio.

Thanks to a wind turbine, solar panels and geothermal heating installed in 2009 at PORTA High School, the district has been saving about $350,000 a year in energy costs, School Superintendent Matt Brue said.

Now, a former student who works for Joule Solar Energy in New Orleans has nominated PORTA Central School for a program that aims to bring solar panels to schools through crowdfunding

Oakland, Calif.-based Mosaic offers an online platform for individuals to invest in solar projects.

When Bob O’Hara received an email from Mosaic saying that the company was looking for schools to work with, he thought of PORTA Central.

O’Hara, 29, attended PORTA schools through eighth grade before enrolling at Sacred Heart-Griffin High School in Springfield. He moved to New Orleans after graduating in 2002 to attend Tulane University, but he still visits his parents in Petersburg regularly.

He likes to check out the wind turbine at the high school on his visits and thought PORTA Central would be a good candidate for solar panels because of its long, south-facing roofline.

O’Hara said he also knows the district has been facing budget cuts due to dwindling state funding.

“One way to be able to invest in a school is to help them with their energy costs,” he said.

Even Georgia Has Tough Energy Codes Now – Some things have changed

Posted on by

Other things have not changed. I mean we are still burning coal to fuel electric generators, 30 years after we should have stopped. We still flirt with the idea of Nuclear Powered power plants. But here is part of the Georgia Code, a State not known for anything progressive.

http://www.southface.org/learning-center/library/res-code-faq#24

22.    What is the difference between a mass wall and a basement wall, and what are the insulation requirements for both?

A mass wall is a heavy wall that is more than half above grade wall and is constructed of a fairly massive material (e.g., concrete, block, insulated concrete forms, masonry cavity, non-veneered brick , adobe, compressed block, rammed earth, and solid logs). A basement wall is a wall that is more than half below grade and encloses conditioned space. Insulation requirements for basement walls and mass walls depend on the location of the insulation and the type of insulation (whether it is continuous or insulation installed in a cavity). Requirements also vary by climate zone. Below is a table detailing the insulation requirements in the energy code.

Wall Type Insulation Location and Type Climate Zone 4 Climate Zone 3 Climate Zone 2
Basement Wall Interior – Continuous R-10 R-5 R-0
Basement Wall Interior – Cavity R-13 R-13 R-13
Mass Wall Interior-Cavity R-13 R-13 R-13
Mass Wall Exterior or Integral- Continuous R-5 R-5 R-4

220 Megs Of Solar Power – The revolution gains speed

I promised Emily Hois that I would link up with her organization, Solar Reviews, last week. Since I am only blogging once a week, it took awhile to honor her request.  So here it is. Great story about where the world is going.

Report Anticipates 220 new Gigawatts of Distributed Solar Generation by 2018

by Chris Meehan on 04/29/2013 in Alternative Energy, Renewable Energy, Solar Cells, Solar Energy, Solar Panels, Solar Power, Solar Rebates

A recent Navigant Research report anticipates that the world will add 220 new gigawatts of distributed solar photovoltaics by 2018 as solar comes into parity with other energy sources, creating $540.3 billion in revenue in the process. That’s a significant jump in the amount of solar that’s currently installed throughout world, which the European Photovoltaic Industry Association (EPIA) said reached 100 gigawatts at the end of 2012.

In recent years, much of the growth in solar is attributable to the giant PV projects being installed to meet utility demand in certain markets. The Navigant report anticipates that just the distributed generation projects—or projects under 1 megawatt in

size—being installed over the next five years will more than double the world’s total solar capacity that’s now online. “Used in applications ranging from residential to small commercial

to industrial settings, distributed solar generation offers significant benefits to consumers while adding resiliency to an electric grid evolving beyond the traditional centralized model,” says Dexter Gauntlett, research analyst with Navigant Research. “Though this market is still primarily driven by government incentives, distributed solar PV will continue its steady march toward grid parity in major markets over the next few years.”

The report anticipates the solar market is transitioning from one that relies on a financial and engineering model based on the wants and needs of utilities to own or source electric generation from large projects to a more diverse model. Under the emerging model, both the sources of generation and the ownership of the generation assets will be more diverse, include third-party financing from companies like SolarCity and SunRun and other new financing mechanisms. These changes will partly be driven by some of distributed solar’s advantages, which include generating electricity onsite to offset the need to build new transmission capacity while avoiding line losses, according to Navigant.

The Nest Thermostat Is A Smart One – A utility company’s wet dream

Posted on by

I think that the Smart Grid is a 2 edged sword. On the one hand it makes integrating renewable energy sources into the grid much easier. On the other hand it could be a step towards big brother. Whatever the case it is coming no matter what.

How Nest Will Save You More Money By Teaming Up With Utility Suppliers

Jamie Condliffe

The smart thermostat from Nest just got a little smarter: by teaming up with utility providers, the device can now predict when power will be in high demand and price, and tweak your heating accordingly.

The new system links the device to a collective, cloud-based knowledge of utility companies. If you’re with an Energy Services-aware power company, the thermostat will learn of upcoming peak energy periods—where power is in high demand and prices rocket as a result—which are sometimes known as rush hours. With that data, it will fine tune your heating, using less energy while it’s expensive.

The cloud will also feed the device data about seasonal discounts, allowing it to fine tune the heating to save you as much cash as possible over the longer term, too. Sadly, only Austin Energy, Green Mountain Energy, Reliant and Southern California Edison have joined forces to make the scheme happen so far. There are deals to be had with provides, though—customers of National Grid can get a $100 rebate through Nest, and Reliant offer a free thermostat with some plans—and it seems likely that other provides will join the fold soon.

Phase Nuclear Power Out Of The USA – Finally somebody had the guts to say it

This is so big that I just had to find the original source. Once I got to the source the article did not carry the same headline as the inflammatory piece from Washington Blog but in the last paragraph he does imply phasing out the nukes. He also points out that no upgrades have been ordered in response to Fukushima nor included in the new licenses issue. This IS the insanity of Nuclear Generation of electricity.

INTERVIEW: Former U.S. nuke watchdog chair says regulators must stay independent

March 14, 2013

By SHIRO NAMEKATA/ Correspondent

As it is poised to impose strict regulatory measures on the operation of nuclear power plants, the Nuclear Regulation Authority is increasingly met by opposition that it is making the resumption of plants that are currently offline virtually impossible.

In a recent interview with The Asahi Shimbun in Washington, Gregory Jaczko, former chairman of the U.S. Nuclear Regulatory Commission (NRC), said it is crucial for a nuclear watchdog to stay independent from the nuclear industry.

Jaczko, who, unlike his four colleagues, opposed the first new construction and operation of a nuclear plant in the United States since the 1979 Three Mile Island accident, also discussed the future of nuclear energy. Excerpts from the interview follow:
