TEPCO using realtime information to help reduce energy consumption in Japan

TEPCO realtime energy chart

TEPCO, the Japanese power company who own the Fukushima nuclear power plant, are in an unenviable position. Their Fukushima nuclear power plant is the site of one of the world’s worst industrial accidents, they have been accused of not just incompetence but of falsifying safety records and yet they have to continue to supply power to Japan.

Japan itself is facing some significant challenges – only 17 of its 54 nuclear power reactors are operational heading into August, traditionally its month of peak demand. Japan needs to try to avoid rolling blackouts, and TEPCO has stepped up to helping out.

TEPCO energy message

TEPCO energy message

On TEPCO’s home page they give top line data for the maximum demand for the day, as well as the maximum amount that will be able to be supplied. As long as the demand doesn’t exceed the supply, no blackouts.

TEPCO have gone further though with a realtime chart of energy demand (updated every five minutes) versus maximum supply and also graphed against the demand on the same day in 2010 (see the chart at the top of this post). We have long argued here on GreenMonk that giving people access to information will help change behaviour. This campaign is a great example of realtime energy information in action and it appears to be helping because electricity consumption is down around 15% on last year.

This information is certainly not the only thing helping people reduce their electricity consumption – TEPCO and others also have energy reduction tips on their website and the tragedy of the Earthquake, followed by the devastating tsunami galvanised a sense of national unity, such that now anyone seen to be wasting scarce electricity is ostracised.

People and companies are turning off lights, removing bulbs, changing the thermostat on air conditioning units in a way that would previously have been thought impossible. In fact a certain pride is creeping into the campaign. Tatsuo Nakahara, administrative manager at Meiwa Rubber, a manufacturer of printing equipment with factories in Tokyo, said in an interview quoted in the New York Times

The government?s figure is 15 percent, but we?re aiming to cut by 25 percent

He added that in the months after the March disaster, the company had already succeeded in conserving 20 percent.

Can this effort be sustained? Only time will tell but if the Japanese can get through August, they’ll have passed through the worst of it. They should consider also giving people individual energy management dashboards and something else that may help maintain the momentum, as I have posited here previously, is the addition of social media and gaming to the effort. Letting people share their energy reduction achievements with their social networks, setting targets for reductions, creating leaderboards and awarding achievement badges etc.

TEPCO may want to seriously consider this. Its reputation, nationally and internationally, is in shreds. If they can be seen now as an agent of good in this crisis, they may be able to resurrect some bit of pride in their brand.

Friday Green Numbers round-up for April 29th 2011

Green Numbers

And here is a round-up of this week’s Green numbers…

  1. UN agency offers $10,000 cash for green phone application

    The United Nations telecommunications agency has launched a contest that will reward the winner with $10,000 for devising the most innovative ?app,? or mobile telephone application, that tackles the subject of climate change.

    ITU has launched a Green ICT Application Challenge to find the best and most innovative idea for a climate change focused app. The winning concept will be awarded USD10,000, thanks to challenge sponsors Research in Motion (RIM) and Telef?nica.

    As well as the cash prize, the winner will… Read on

  2. Unsure about nuclear power? Here’s the five questions you must answer to decide

    Containing the elemental forces that rage inside a nuclear reactor is one of the great achievements of science, but losing control, as happened 25 years ago on Tuesday at Chernobyl, is one of its greatest failures.

    So what to think of nuclear power? People often ask me if I support or oppose the building of new nuclear power stations, presuming I think that … Read on

  3. Feds: Global warming will cut West’s water 8-14% by 2050

    Even as California seemed to be shaking off the effects of its most recent drought, U.S. officials gave a word of warning Monday: water supplies could drop sharply in coming decades because of global warming.

    A new report from the Bureau of Reclamation says runoff to major western river basins, including the San Joaquin and Colorado that supply California, could drop 8 to 14 percent overall by 2050.

    And while the agency’s projections show that another California water source, the Sacramento River, could see a… Read on

  4. A Battery That Charges in Seconds

    Imagine being able to charge your cell phone in a matter of seconds or your laptop in a few minutes. That might soon be possible, thanks to a new kind of nanostructured battery electrode developed by scientists at the University of Illinois, Urbana-Champaign. The researchers found that their electrode can charge and discharge up to 100 times faster than existing devices while holding the same amount of energy.

    High-storage batteries that could charge and discharge quickly might make a number of still-marginal technologies much more attractive. For example, if you could recharge an electric car in minutes rather than hours, filling up your battery at a charging station would take no longer than the amount of time it takes to buy a tank of gas. And batteries that gave up their stored energy quickly could mean uninterrupted solar power… Read on

  5. Legalizing Marijuana Could Reduce Its Energy Consumption 75%

    When we found out a couple week ago that the marijuana industry is responsible for 1% of all US electricity consumption, the first and perhaps obvious big question that popped to my mind was how would that figure change if pot was legalized? Surely the electricity bill is so high in part because of the necessity of indoor grow operations to avoid detection.

    Well, as the infographic excerpted below shows, legalization of pot would indeed radically slash the energy footprint of the marijuana industry… Read on

  6. High Gas Prices: Supply and Demand – Efficiency and Better Cars Will Fuel America Faster than Drilling

    The United States consumes 19 million barrels of oil a day, 25 percent of the global supply, but we have less than 2 percent of the world?s proved oil reserves. That means no amount of domestic drilling will reduce gas prices or provide enough to meet America?s daily demand for oil. The only solution: develop better cars and cleaner, safer sources of fuel. By 2025… Read on

  7. America?s Nuclear Nightmare – The U.S. has 31 reactors just like Japan?s ? but regulators are ignoring the risks and boosting industry profits

    The NRC’s “safety-last” attitude recalls the industry-friendly approach to regulation that resulted in the BP disaster in the Gulf of Mexico last year. Nuclear reactors were built to last only 40 years, but the NRC has repeatedly greenlighted industry requests to keep the aging nukes running for another two decades: Of the 63 applications the NRC has received for license extensions, it has approved all 63.

    In some cases, according to the agency’s own Office of the Inspector General, NRC inspectors failed to verify the authenticity of safety information submitted by the industry, opting to simply cut and paste sections of the applications into their own safety reviews. That’s particularly frightening given that some of America’s most troubled reactors… Read on

  8. Google?s Clean Energy Projects (7 Big Ones)

    Google is one of the largest clean energy corporate leaders in the U.S. If we had more Googles (and fewer Facebooks or Apples), it looks like we?d have a much brighter future. Hopefully, others will follow Google?s lead sooner than later on this front, or even try to one-up it. For now, though, it?s clean energy enthusiasm and investments are hard to compete with.

    With a number of recent clean energy project announcements… Read on

  9. UK Electric car scheme has only 534 takers

    The government’s hoped-for electric car revolution, jump-started by a ?5,000 purchase grant per vehicle, is getting off to a slow start with just over 500 people signing up to the scheme since it was introduced at the start of the year.

    The figures, revealed in a parliamentary answer by the junior transport minister Norman Baker, show that 534 electric vehicles were registered to the so-called plug-in car grant during the first quarter of 2011. So far, 213 have been delivered.

    The incentive scheme… Read on

Friday Green Numbers round-up for Feb 25th 2011

Green Numbers

And here is a round-up of this week’s Green numbers…

  1. After 50 Years, Nuclear Power is Still Not Viable without Subsidies, New Report Finds

    Since its inception more than 50 years ago, the U.S. nuclear power industry has been propped up by a generous array of government subsidies that have supported its development and operations. Despite that support, the industry is still not economically viable, according to a report released today by the Union of Concerned Scientists (UCS). The report, ?Nuclear Power: Still Not Viable Without Subsidies,? found that more than 30 subsidies have supported every stage of the nuclear fuel cycle, from uranium mining to long-term waste storage. Added together, these subsidies often have exceeded the average market price of the power produced.

    ?Despite the fact that the nuclear power industry has benefited from decades of government support, the technology is still uneconomic, so the industry is demanding a lot more from taxpayers to build new reactors,? said Ellen Vancko, manager of UCS?s Nuclear Energy and Climate Change Project. ?The cost of this technology continues to …

  2. UN reveals $1.3trn green strategy

    A new sustainable strategy by the United Nations proposes to invest 2pc of wealth generated by the global economy, or some $1.3trn annually, in 10 key sectors.

    The new United Nations Environment Programme (UNEP) report that was released yesterday, when more than 100 environment ministers met in Nairobi, underlines a sustainable public policy and investment path that will not only launch the transition towards a low-carbon, resource-efficient green economy, but will also …

  3. Wind generation is not increasing wholesale electricity prices in Ireland

    The growing levels of wind generation on the Irish electricity network is not increasing wholesale electricity prices, a new study published by EirGrid and the Sustainable Energy Authority of Ireland (SEAI) suggests.

    The report by grid operator EirGrid and the SEAI, employs detailed modelling tools to examine the wholesale prices in the Irish electricity system in 2011, which has a total annual value of an estimated ?2bn.

    The analysis revealed that wind generation lowers wholesale prices by …

  4. 7 Fear Factors That Move Solar Stocks

    Solar companies have seen their stocks head up over the past two months as they?ve been reporting killer sales and profits for 2010 and remain bullish about 2011. Shares of key players, such as SunPower, Suntech Power, First Solar and Trina Solar, all have seen their shares rise about 30 percent or more since the beginning of the year.

    But no stocks can keep climbing forever, and news events that …

  5. OnChip Power, aiming a shrink ray at bulky transformer ‘bricks,’ raises $1.8 million from Venrock

    I am fairly sure that if you manage to raise $1.8 million for your start-up while enrolled in a business school course called “Entrepreneurial Finance,” you are almost guaranteed an A.
    Last week, MIT Sloan student and OnChip Power CEO Vanessa Green was signing the papers on her company’s first round of funding: $1.8 million from Venrock and Arunas Chesonis, chairman of PAETEC Holding and an MIT alumnus.

    OnChip is commercializing new power electronics technology developed at …

  6. Transphorm Unveils Efficient Power Module, $38M From Kleiner, Google Ventures

    Here comes the biggest cleantech startup launch since Bloom Energy: Acompany called Transphorm has emerged from stealth on Wednesday afternoon at Google Venture?s headquarters, touting an energy-efficient power conversion module for power-hungry devices from servers to electric car batteries to solar panels, and an enviable $38 million in venture capital from Kleiner Perkins, Google Ventures, Foundation Capital, and Lux Capital.

    Founded in 2007, Transphorm is looking to make power conversion more energy-efficient and reduce the …

  7. Harvard Study Reveals Coal Energy To Be One of the Most Expensive Forms of Power

    Advocates of coal power argue that it is among the cheapest sources of energy in the United States and allows for lower-cost power. But a new Harvard study found that whatever money is saved in operation costs is completely negated by the cost coal plants inadvertently pass on to the American public: $345 billion.

    These hidden expenses are not borne by miners or utilities, but come from the detrimental side affects of coal burning, like health problems in mining communities and pollution around coal plants. The study is the first to look at the entire cost of coal, from extraction to combustion …

  8. Oil surges nears $120 a barrel on Libya and Middle East fears

    Oil prices soared to almost $120 a barrel on Thursday amid fears that the unrest in Libya and Bahrain could spread to other oil-rich countries in the Middle East, including Saudi Arabia.

    Brent crude leapt $8.54 to $119.79 a barrel, the highest price since August 2008, and later traded at $113.93 a barrel. It closed at…

Green bits and bytes for Feb 24th 2011

Green bits & bytes

.

Some of the Green announcements which passed by my desk this week:

  1. Digital Lumens, maker of Intelligent LED Lighting Systems, today announced that its Midbay fixture is the only ?Recognized Winner? in the Industrial Category of the Next Generation Luminaires competition. The competition is jointly organized by the Illuminating Engineering Society of North America (IESNA), the International Association of Lighting Designers (IALD) and the U.S. Department of Energy (DOE), as part of a broad initiative to advance solid-state lighting technology and adoption.
  2. Symphony Environmental Technologies, a maker of degradeable plastics has announced [PDF] the signing of a 25 year distribution agreement for its products throughout the US. According to their announcement, “The core of Symphony?s business is a suite of chemical formulations called d2w, which turn plastic at the end of its service-life into a material with a completely different molecular structure. At that stage it is no longer a plastic and can be safely bioassimilated in the open environment in the same way as a leaf”
  3. The Union of Concerned Scientists (UCS) released a new report detailing the full range of subsidies that have benefited the commercial nuclear power industry in the United States over the last 50 years. The report found that subsidies for the entire nuclear fuel cycle — from uranium mining to long-term waste storage — have often exceeded the average market price of the power produced. In other words, if the government had purchased power on the open market and given it away for free, it would have been less costly than subsidizing nuclear power plant construction and operation.
  4. The International Aluminium Institute has launched a new Website, Aluminium for Future Generations to highlight the recycling advantages of aluminium products. The site provides data on recycling rates and energy and emissions savings; measures that are central to the aluminium industry’s sustainability strategy of reducing the environmental impact of its facilities, increasing the use of aluminium in energy saving applications and maximising the recycling of products at the end of their useful life.
  5. Environmental Business Journal, a business research publication that provides strategic business intelligence for the environmental industry, announced the winners of its 2010 Business Achievement awards. One of those awarded was Locus Technologies, who were awarded an IT Companies Business Achievement award for ” for growth in revenue, client base, and product introductions”

Some of the Green announcements which passed by my desk this week:

  1. This year’s annual Transmission & Distribution Europe and Smart Grids Europe conference will be held in Copenhagen from 12-14 April. More than 30 utilities, as well as utility experts, regulators and technology giants from all over Europe, as well as the USA, South Africa, Japan and Australia, will be attending. I hope to be there too!
  2. Synapse Energy Economics released a report this week which outlines in detail the enormous hidden health and water impacts of coal and nuclear power in the US.

    Some of the costs mentioned in the report include 200 billion gallons of water withdrawn from America?s water supply each day ? annual costs to society from premature deaths due to power plant pollution so high that they are up to four times the price of all electricity produced in the U.S. ? and four metric tons of high-level radioactive wastes for every terawatt of electricity produced by nuclear reactors, even though there is no long-term storage solution in place.

  3. Optimum Energy, maker of heating, ventilating and air conditioning software solutions, has rolled out a new partner program with enhanced project development tools and training resources. Optimum Energy’s software maximizes the energy reduction potential of high-efficiency, variable speed heating and cooling systems, leading to energy savings for customers and the ability to improve overall project return on investment.
  4. Tropos Networks, maker of wireless IP networks for Smart Grids, has added two new products to its portfolio – the Tropos 1310 Distribution Automation (DA) Mesh Router and their Directional Radio Systems to deliver economical long range, high capacity wireless communications for sparse suburban and rural areas or as backhaul for Tropos Mesh networks.
  5. New York’s Mayor Bloomberg launched an Urban Technology Innovation Center at Columbia university. The center brings together academia, the public sector and companies like IBM to design and deploy new technology that will help the city’s buildings save energy, water and other resources. The challenge is to use advanced IT systems – analytics software and powerful new hardware – to create facilities that reduce energy, streamline operations and optimise real estate use.

Friday Green Numbers round-up 11/19/2010

Green Numbers

And here are this week’s Green numbers…

  1. Smart grids could save the EU ?52 billion annually, according to leading smart grid companies that have teamed up to promote European leadership in smart grids.

    The sizeable savings would arise from reducing losses in the electricity distribution network through automation and encouraging consumers to cut energy consumption with smart meters that provide more accurate and timely information, experts from the Smart Energy Demand Coalition said at its launch yesterday (15 November) in Brussels

    Utilities will also be able to lower the system voltage level and make meter-reading redundant, argued Chris King, chief regulatory officer at eMeter. After deducting necessary costs like the installation of smart meters and new software, the net benefit would still be ?31 billion per year, he said.

  2. Exelon Corp. plans to invest $3 billion to boost the output of its nuclear plants as environmental regulations make competing coal-fired generation more expensive.

    The investment is part of a plan announced Tuesday to spend $5 billion between 2010 and 2015 to increase generation capacity and reduce the company’s carbon footprint.

    The company already has the lowest carbon footprint of any major power producer because 93% its power is generated by its huge fleet of nuclear reactors, which emit almost no carbon dioxide. As Exelon increases its output of nuclear power, the company will close a pair of money-losing coal plants in Pennsylvania.

  3. To reduce emissions of greenhouse gases 10 percent below 1990 levels, Oregon?s PGE (Portland General Electric) plans to replace coal plants with 2,362 MW of wind energy and 557 MW of simple-cycle combustion turbines burning natural gas

    To pay for the new investment in building renewable energy, utility rates will likely rise 13% in 2019, and 25% in 2020, the utility calculates.
    But the other utilities in the state that utilize the regions plentiful hydro can make a gentler transition, as they currently have surplus generation from clean sources in the spring and winter.

  4. The Carbon Disclosure Project launches first water disclosure report on world?s largest companies

    The report findings show that water is already impacting business operations with 96% of responding companies able to identify whether or not they are exposed to water risk and more than half of those reporting risks classifying them as current or near-term (1-5 years). 39% of companies are already experiencing detrimental impacts relating to water including disruption to operations from drought or flooding, declining water quality necessitating costly on-site pre-treatment, and increases in water prices, as well as fines and litigation relating to pollution incidents.

    Water security is already high on the corporate agenda with 67% reporting responsibility for water-related issues at the board or executive committee level. The majority of companies (89%) have already developed specific water policies, strategies and plans, and 60% have set water-related performance targets.

Is there really any need for baseload power?

No nuclear waste

Photo credit wonderferret

The electricity grid may not need “baseload” generation sources like coal and nuclear to backup the variability of supply from renewables.

Jon Wellinghof is the Chairman of the US Federal Energy Regulatory Commission (FERC). FERC is an independent agency that amongst other things, regulates the interstate transmission of electricity, natural gas, and oil – for more on FERC’s responsibilities see their About page. Chairman Wellinghoff has been involved in the energy industry for 30 years and appointed to the FERC as a commissioner by then president Bush in 2006.

Last year, shortly after being appointed as Chairman of the FERC, Mr Wellinghoff announced that:

No new nuclear or coal plants may ever be needed in the United States….

Wellinghoff said renewables like wind, solar and biomass will provide enough energy to meet baseload capacity and future energy demands. Nuclear and coal plants are too expensive, he added.

“I think baseload capacity is going to become an anachronism,” he said. “Baseload capacity really used to only mean in an economic dispatch, which you dispatch first, what would be the cheapest thing to do. Well, ultimately wind’s going to be the cheapest thing to do, so you’ll dispatch that first.”…

“What you have to do, is you have to be able to shape it,” he added. “And if you can shape wind and you can effectively get capacity available for you for all your loads.

“So if you can shape your renewables, you don’t need fossil fuel or nuclear plants to run all the time. And, in fact, most plants running all the time in your system are an impediment because they’re very inflexible. You can’t ramp up and ramp down a nuclear plant. And if you have instead the ability to ramp up and ramp down loads in ways that can shape the entire system, then the old concept of baseload becomes an anachronism.”

This was quite an unusual contention at the time (and still is) and despite the Chairman’s many years working in the sector it was, by and large, ignored – even by the administration who had appointed him to the Chairmanship. In fact, the Obama administration has since announced financial backing for new nuclear power plants.

However, a study published last week by the Maryland-based Institute for Energy and Environmental Research backs Chairman Wellinghoff’s assertion. In a study of North Carolina’s electricity needs it concluded backup generation requirements would be modest for a system based largely on solar and wind power, combined with efficiency, hydroelectric power, and other renewable sources like landfill gas:

“Even though the wind does not blow nor the sun shine all the time, careful management, readily available storage and other renewable sources, can produce nearly all the electricity North Carolinians consume,” explained Dr. John Blackburn, the study’s author. Dr. Blackburn is Professor Emeritus of Economics and former Chancellor at Duke University.

“Critics of renewable power point out that solar and wind sources are intermittent,” Dr. Blackburn continued. “The truth is that solar and wind are complementary in North Carolina. Wind speeds are usually higher at night than in the daytime. They also blow faster in winter than summer. Solar generation, on the other hand, takes place in the daytime. Sunlight is only half as strong in winter as in summertime. Drawing wind power from different areas — the coast, mountains, the sounds or the ocean — reduces variations in generation. Using wind and solar in tandem is even more reliable. Together, they can generate three-fourths of the state’s electricity. When hydroelectric and other renewable sources are added, the gap to be filled is surprisingly small. Only six percent of North Carolina’s electricity would have to come from conventional power plants or from other systems.”

With larger and more inter-connected electricity grids, the requirement for baseload falls even further because the greater the geographical spread of your grid, the greater the chances that the wind will be blowing or the sun shining in some parts of it.

So, is there really any need for baseload power any more, or is this now just a myth perpetuated by those with vested interests?
