    Solar Power in Germany

    Solar Power Accounted for 10 Percent of Germany’s Electricity in May

    “Germany’s decision to replace nuclear energy with other sources is proving to not only be possible, but is creating many valuable prospects for the renewables sector. The continued strength of the solar market has sparked greater investment from abroad,” said Tobias Homann, photovoltaic industry expert from Germany Trade & Invest in Berlin.

    Thirty-six nonprofit groups with more than 1.1 million members have formed a coalition to advance a "serious renewable energy agenda" regardless of who occupies the White House or which party controls Congress after the November elections.

    The coalition's "American Clean Energy Agenda" calls for phasing out nuclear power, natural gas, coal and industrial biomass "and driving a grand transition to efficient use of renewable, non-polluting resources."

    As signed by the supporting citizen organizations, the American Clean Energy Agenda states, "The time is now for a new, grassroots-driven politics to bring about a renewable energy future. As Congress debates major new public investments in energy, we need to ensure that our taxpayer dollars support an energy system that protects public health, promotes energy independence and ensures the economic well being of all Americans."

    "Whether it be oil and shale gas drilling, coal mining or nuclear energy, this coalition of grassroots experts have witnessed firsthand the devastating impacts of mountaintop mining removal, fracking for natural gas, uranium mining and nuclear waste," said White. "We've banded together to take back our clean energy future from the seemingly all-powerful big oil, natural gas and energy companies that continue to spend hundreds of millions of dollars to keep us trapped in a dirty energy economy."

      MaidenHeaven, why are the groups going after industrial biomass? Does that mean corn waste and things like that?

      Had thought biomass could produce clean energy, but I guess it depends on what it is, and how it's utilized.

    Thanks Enenews Admin for adding this forum. Am needing to refresh my knowledge of converting to passive solar power and such …. Am sure there is plenty to learn after taking a hiatus from learning about alternative energy for 20 years.

    When I last looked at this, people studying global warming were just beginning to ask questions like how could it affect phytoplankton, and how much methane is produced by burping cows all over the planet. And are those cow burps a significant source of methane? (And things like that for economic and international policy studies.)

    For anyone interested, the US DOE's National Renewable Energy Laboratory issued a new report on potentials for developing renewable sources in the US.

    One conclusion I see pretty easy to develop from their numbers is that we can replace all our fossil fuel and nuclear production of electricity by exploiting less than 1.18% of our available renewable resources.

    You can find my article on it at http://geoharvey.wordpress.com/good-news-on-the-potential-for-renewable-power/

    Germany Installs 1 Nuclear Plant Worth Of Wind Energy In First Half Of 2012

    More than 400 turbines with a combined capacity of some 1,000 megawatts — roughly equivalent to one nuclear power plant — were installed, up from about 800 megawatt in same period last year, the Wind Energy Association said.

    Before Fukushima, nuclear power in Germany produced a little more than 20 percent of the country's electricity needs — about the same share it had in the U.S. and in Japan. It has since fallen well below 20 percent.

    New Bladeless Wind Turbine Claimed to be Twice as Efficient as Conventional Designs

    According to the company, their zero-blade technology devices are capable of overcoming the Betz' limit, which states that no turbine can capture more than 59.3 percent of the kinetic energy of the wind. An average wind turbine captures only 30 to 40%, while the Saphon turbine is said to be 2.3 times more efficient. Additionally, the cost is expected to be 45% less than a conventional turbine, mostly due to the fact that there are no blades, no hub, and no gearbox on the units.

    The Saphon Zero Blade technology is different in other ways as well, most significantly being storage of energy. Most of the kinetic energy can be stored (via a hydraulic accumulator) or converted to electricity with a hydraulic motor and generator.

    For many around the world who have no access to running water or electricity, the use of an electrically-powered washing machine and dryer is not an option.

    Working in concert with a South American NGO and the Safe Agua Peru project, Los Angeles-based design students Alex Cabunoc and Ji A You created the GiraDora, a compact foot-powered washing machine that drastically reduces the time needed to hand-wash laundry.

    To operate GiraDora, the user sits on top of the bucket to stabilize the contents, agitating the clothes by a foot pedal. Afterwards, the greywater is drained and reused, and the clothes are spun dry via the same action.

    JAPAN PREPARES TO TAP INTO GEOTHERMAL POWERAUGUST 11, 2012

    http://fukushimaupdate.com/japan-prepares-to-tap-into-geothermal-power/

    "Almost 18 months after the nuclear accident at the nearby Fukushima No. 1 power plant, that same natural resource is about to turn this spa resort into a trailblazer for the country’s push towards renewable energy.

    By spring 2014, Tsuchiyu, 15 kilometres from Fukushima, will be generating 250 kilowatts of electricity – about a quarter of the city’s total needs – at a geothermal plant hidden away in the surrounding mountains.

    The plant will be the first to be built inside a national park, a controversial move that only became possible after the environment ministry recently relaxed regulations on developing protected areas."

    The sunflower inspired a researcher to create a new solar panel system that rotates toward the sun, increasing the energy harvesting capability by 10 percent.

    A field of young sunflowers will slowly rotate from east to west during the course of a sunny day, each leaf seeking out as much sunlight as possible as the sun moves across the sky through an adaptation called heliotropism.

    Unlike other "active" solar systems that track the sun's position with GPS and reposition panels with motors, electrical and computer engineering professor Hongrui Jiang's concept leverages the properties of unique materials in concert to create a passive method of re-orienting solar panels in the direction of the most direct sunlight.

    New Thin-Film Solar Cells More Efficient, Cheaper

    IBM researchers have created new thin-film solar cells that are more efficient and less expensive than any others of their kind. The solar cells are made from readily available copper, zinc, tin and selenium (CZTS), and can be manufactured using simple ink-based techniques like printing. With 11.1 percent efficiency, they are 10 percent better than any before.

    The new technology may also enable thin-film solar cells to reach many more people. Because of the rarity and cost of indium and gallium, IBM says that current CIGS cells only have the potential to produce 100 gigawatts of electricity per year. With CZTS tech, that number could jump to as much as 500 gigawatts. The solar cells are still in development, and the researchers hope to continue to push for even more efficiency.

    Suburbs Putting Solar Farms On Landfills

    Landfills are typically unusable as land after being filled in and left to rot, as the methane being released from deep within them is toxic and responsible for about one-third of all methane emissions in the US. And while some landfills have been fitted with systems to capture and burn the methane in order to generate electricity, most of them sit idle in towns across the country waiting for someone to figure out how to reuse the space.

    In New Jersey for example, the state’s main utility company Public Service Electric and Gas recently began construction on a six-acre solar farm. Once completed, it will generate 1 MW of electricity, enough to power 1,000 average homes.

    Massachusetts also has its eyes on utilizing the land once used for waste disposal. According to the Boston Globe, the city of Canton will soon be home to the largest solar energy system installed on landfill space in the country, covering 15 acres with 24,000 photovoltaic panels. As of June 2012, twenty-three other Massachusetts towns have applied for permits to do the same.

    Microwave Ovens May Help Produce Lower Cost Solar Energy Technology

    "All of the elements used in this new compound are benign and inexpensive, and should have good solar cell performance," said Greg Herman, an associate professor in the School of Chemical, Biological and Environmental Engineering at OSU.

    These thin-film photovoltaic technologies offer a low cost, high volume approach to manufacturing solar cells. A new approach is to create them as an ink composed of nanoparticles, which could be rolled or sprayed — by approaches such as old-fashioned inkjet printing — to create solar cells.

    To further streamline that process, researchers have now succeeded in using microwave heating, instead of conventional heating, to reduce reaction times to minutes or seconds, and allow for great control over the production process. This "one-pot" synthesis is fast, cheap and uses less energy, researchers say, and has been utilized to successfully create nanoparticle inks that were used to fabricate a photovoltaic device.

    Solar Power Much Cheaper to Produce Than Most Analysts Realize, Study Finds

    The public is being kept in the dark about the viability of solar photovoltaic energy, according to a study conducted at Queen's University.

    Dr. Pearce says some studies don't consider the 70 per cent reduction in the cost of solar panels since 2009 . Furthermore, he says research now shows the productivity of top-of-the-line solar panels only drops between 0.1 and 0.2 percent annually, which is much less than the one per cent used in many cost analyses.

    Microwave ovens are NOT banned in Russia for health reasons or any other reasons. The USSR banned them briefly in the 1970's for economic reasons.

    " IRENA

    The International Renewable Energy Agency (IRENA) is an intergovernmental organisation dedicated to renewable energy.

    In accordance with its Statute, IRENA's objective is to "promote the widespread and increased adoption and the sustainable use of all forms of renewable energy". This concerns all forms of energy produced from renewable sources in a sustainable manner and includes bioenergy, geothermal energy, hydropower, ocean, solar and wind energy.

    As of May 2012, the membership of IRENA comprised 158 States and the European Union (EU), out of which 94 States and the EU have ratified the Statute."

    TThere never has been good cause to poison people, animals, and plants, except as driven by greed, & lust for personal power.

    IMHO we must collectively wary of how the policies & law on "sustainable" technologies are implemented. I don't care to become part of a "smart grid" (i.e. stupid grid) & have my appliances "snitch" on me — so that some nosy government agency can use the info. to increase its bloated budget.

    Agencies could drum up cause for suspicion could use "renewables policy" & the stupid grid to make anyone & everyone a potential "suspect." Am 100% in support of renewables, but wary of "sustainable" concept & what TPTB's potential fishing expeditions, under guise of sustainability.

    EDUCATE THE PEOPLE!

    The following simple, but poignant FACTOID needs to be brought back FRONT AND CENTER for all of the MACFLY's out there that choose to ignore the truth!

    http://enenews.com/forum-alternative-energy/comment-page-2#comment-262476

    <<<<<One of the first arguments to come out of an ill-informed (or blatant lying) pro-nuker's mouth is "you'll have brown-outs; what happens when the sun goes down."

    The simple illustration aconfirms that with thermal salt batteries:

    (1) 24/7 baseload power can be provided.
    (2) A total land-mass less than 80 miles X 80 miles can meet electrical requirements of ALL 100 million US households.
    (3) No excess heat (and CO2 emmissions, etc.) is generated, using only incident solar radiation.

    The 'light-bulb-goes-off' concept to first hook-them is simply this:
    An 80 mile X 80 mile landmass of solar tower concentrator plants is all that is needed meet all 100million US household needs. Such a number can be simply verified without uncertainty or obsfucation.>>>

    THAT'S IT! AN 80×80 SQUARE MILE LANDMASS can meet the electrical needs of all 100 MILLION USA households using 'SOLAR TOWER CONCENTRATOR' technology.

    Now, if 'WE' add in the addtional potential for WIND ENERGY, PHOTOVOLTAICS, GEOTHERMAL, BIOMASS, etc., one may start to wonder WHETHER WE'VE REALLY BEEN HAD ALL OF THESE YEARS, by being captured to TOXIX ENERGY INDUSTRIES, NUKE POWER BEING CHIEF!

    EDF caves in…sucks up to frackers:

    "we want to be as clear as we can be as to why EDF is so deeply involved in championing strong regulation of natural gas."

    http://blogs.edf.org/energyexchange/2012/09/10/why-edf-is-working-on-natural-gas/

    "Our view on natural gas is shaped by three basic facts. First, hydraulic fracturing is already a common practice in the oil and gas industry. Over 90 percent of new onshore oil and gas development taking place in the United States today involves some form of hydraulic fracturing, and shale gas accounts for a rapidly increasing percentage of total natural gas production—from 16% in 2009 to more than 30% today. In short, hydraulic fracturing is not going away any time soon."

    SP: "Not going away anytime soon"… that's what they said about the Nazis after they imvaded Poland. That is s damn poor excuse proffered by the EDF for the abuses of the environment created by out of control frackers.

    We won't need a second Fukushima to kill off the American population…we will just poison our water resources forever and die twice as fast.

    Naked apes have never learned to stop crapping in their water holes…Big Brother lets energy businesses crap in the water at an extinction-level pace.

    We will regret the low prices of fracking-derived oil and natural gas very soon. The bad public water you drink now is only a fraction of the poisonous liquids we will see in ten years.

    Plastic-to-oil machine

    The contraption, which is the first of its kind in North America, looks like a mad scientist’s workshop and takes over an area roughly the size of a pool table at the warehouse at P&M Recycling.

    Plastic that has been cut into coarse granules is fed into a trough, moves through various tubes and chambers until it turns into a gas and is cooled.

    At the end, a light-coloured oil drips from a spigot into a receptacle.

    The machine processes about 10 kilograms of plastic, producing about 10 litres of oil every hour, and can run continuously.

    The oil that comes out is a blend of gasoline, diesel, kerosene, and some heavy oils. It can be fed directly into an oil furnace, or could be processed further into something that could go straight into a diesel engine.

    I just posted a couple items on my daily energy blog.
    I THINK THIS MIGHT TURN OUT TO BE THE MOST IMPORTANT I HAVE SEEN RECENTLY: Researchers at Murdoch University have developed a water-based sodium battery, similar to a lithium battery, that can be used for utility-scale energy storage.
    Also, China keeps increasing its goals for solar capacity. Originally, it was 5 GW by 2015. They had to increase that three times, because they are installing new capacity faster and faster – 7 GW in 2012 alone. Their current goal is 40 GW for 2015. They will probably have to increase the goal for 2020 from 50 GW to 100GW.

    Hamburg, Germany here. Just wanted to share with you, that I am going to install photovoltaik on our roof in october, as much as possible, and it feels soooo good!

    I planned this for 15 years now (Our roof is far from ideal for PV. So we always got discouraged.) and now I am so excited to finally DO it.

    We will get 14.000 kWh each year. That is enough for our house with two families + an office and at least 30.000km/year with an electric car in the future.

    It is a big deal for me, and a lot of research and money go into it, there will be no considerable rate of return, but we will have secure and clean energy, and I enjoy very much to be part of the change. Just wanted to let everybody now, that it feels good to do the right thing – so much better then buying electricity from coal or nuclear. We ordinary people make the difference / make the change.

    German Grid Reaches Record Reliability in 2011 Thanks to Renewables

    The country not only avoided major blackouts during the winter, “but its availability actually increased over the average going back to 2006, when reporting began,” thanks in part to the recent increases in small-scale renewable energy.

    Such a high level of grid reliability is possible for any country with a high penetration level of intermittent wind and solar power. As an example, Denmark, with an even greater share of wind power in Germany, has a very reliable grid also. And an even better example is the great increase in grid reliability that Spain has experienced as they have increased their wind and solar power, as the chart above shows.

      Part of this improvement may be helped by changes in their power grid. Germany made changes that took the power grid out of the hands of four big companies. The grid is now being bought back by cities and regional authorities who originally owned the power grid but had sold it off to big power companies over the years. This put more entities and more of the people back in control of the power grid. Most wind farms in Germany are also owned by smaller companies or regional authorities. This has helped to decentralise power production and encourage competition.

        Our research finds that just one typical wind farm of 250-MW creates 1,079 direct jobs over the lifetime of the project. Already 25 projects of similar or greater size have already been built in the U.S., and another 100 wind projects sized from 150-MW to 250-MW are in operation.

        In addition to jobs, wind projects boost revenues and create new markets for a wide-range of companies across many different industries. Each of the 14 steps in building a wind farm outlined in this report represents new opportunities for dozens of companies across many different cities and states.

        Unfortunately, misconceptions about the viability of wind power downplay the strong economic and employment benefits of wind power, and ignore the continued innovation in this sector. This report is ultimately an exercise in telling the story of one large wind farm — showing the full economic impact — to demonstrate the impressive value created by these projects, to highlight the opportunities for American companies, communities and workers, and to caution what is at risk if we don’t continue to invest in these renewable technologies.

    Most islands are well endowed with one or more renewable energy source — rivers, waterfalls, wind, sunshine, biomass, wave power, geothermal deposits — yet virtually all remain heavily or entirely reliant on imported fossil fuels to produce electricity and power transport.

    “The Renewables and Islands Global Summit” in Malta was co-hosted by the 100-nation International Renewable Energy Agency (IRENA) based in Abu Dhabi and by the government of Malta — a 316 sq km Mediterranean island republic of 410,000 inhabitants, and EU’s smallest member state.

    Representatives (including 15 ministers) from 26 developing Pacific, Caribbean and African developing island nations and from coastal developing states with islands reported a wide range of renewables deployment, from detailed long-term plans and ongoing activities to reach up to 100 percent renewables, to admissions of very low deployment and no firm goals or plans yet.

    Hi all,

    There was a lot about renewable energy in the news today:

    In Japan, renewable power generation is growing at about twice the rate needed to achieve government goals.

    The new Japanese Nuclear Regulation Authority will not use the results of stress tests performed by its predecessor. This sets nuclear restarts back.

    The European Commission’s Joint Research Center says renewable energy generation is the only set of power sources that offers price reductions. All others offer price increases.

    Germany now has over 30GW PV of solar capacity.

    A report from GlobalData says renewable power generation in the UK will equal thermal by 2025.

    Denmark is now getting 40% of its power from renewable sources.

    Scottish Energy Minister Fergus Ewing, talking of the country’s goal of 100% electrical generation by 2020, said, “We are confident, that the target, while being ambitious, is achievable.”

    There are links to articles on all of these at my blog site:

    Wind’s Latest Problem: It Makes Power Too Cheap
    “Utilities don’t like wind not because it’s not competitive, but because it brings prices down for their existing assets, thus lowering their revenues and their profits. Thus the permanent propaganda campaign against wind. The reality is that wind power brings prices down for consumers….”

    Solar power is contagious People are more likely to install a solar panel on their home if their neighbors have one.

    The study also shows that the visibility of the panels and word-of-mouth led to larger installations. "If my neighbor installs a solar panel and tells me he's saving money and he's really excited about it, it's likely I'll go ahead and do the same thing," said Gillingham. "Then there are others who'll install because they don't want to be one-upped by their neighbors."
