Smart Meters in Every UK Home by 2020

In energy conservation, green policy on May 14, 2009 at 10:07 pm

UK Government Reveals Ambitious Smart Meter Plans
The European Union has already made moves to mandate smart meters, but according to the Guardian, UK will be following suit. The British Government has revealed that it will be ensuring that every UK home is fitted with a smart meter by the year 2020.

Here’s more from The Guardian:

“The meters most of us have in our homes were designed for a different age, before climate change. Now we need to get smarter with our energy … so it’s important we design a system that brings best value to everyone involved.”

Ed Miliband, Energy & Climate Change Secretary

Energy companies welcomed the switch, which will reduce their running costs by making meter readers obsolete and eliminating the customer service time spent on dealing with estimated bills. Consumers and small business owners could benefit from savings achieved through increased awareness of their energy use.

Previous studies have shown that smart meters encourage homeowners to cut their energy use by 3-15%, although experts warn that the technology requires consumer education and is not an “install and forget” energy-efficiency measure like loft insulation.

It’s certainly true that instantaneous feedback on our energy consumption can encourage more efficient behavior but in order to be successful, we’ll need efforts to educate the public about how to get the most out of these meters, and tips to reduce energy consumption in the household.

Energy Department’s Weatherization Program and its Benefits

For implementation of the American Recovery and Reinvestment Act (ARRA), theUS Department of Energy has announced that US$5 billion dollars allocated for theWeatherization Assistance Program, will be used to insulate, seal leaks, or modernize heating and air conditioning equipment for low-income families, “at a cost of up to $6,500 per home.” The assistance is for families making up to approximately $44,000 per year in the lower 48 states, $55,140 per year in Alaska, and $50,720 per year in Hawaii.

Details also were announced forState Energy Program; but, in this post we’ll have a closer look at just the Weatherization Program.

No handouts.
No money is handed out to individuals to cover costs incurred in “weatherizing.” Local contractors are paid by a state-level administering agency. And, in a pleasing development, quarterly reporting by the local administering agency is done electronically! (trees saved)

DOE expects Weatherization to:

  • result in 32% saved on an average family energy bill ( $350 per year depending on fuel prices).
  • support at least 8,000 technical jobs in low-income communities.
  • result in a local economic multiplier of three (see explanatory post here).
  • increase the value of weatherized housing stock, helping make up the shortage of affordable housing.

If you are interested in applying for Weatherization, qualification requirements and contacts are listed here.

Oak Ridge National Labs, Weatherization and SEP Support Program, provides technical assistance. There are some fascinating engineering studies on this topic, by ORNL, listed here.

Thermal Photovoltaics Breakthrough Boasts Theoretical Efficiency of 85%

Theoretical Efficiency of 85%!
Thermal photovoltaics has been around since the 1960s, but it never produced enough power to compete with solar thermal using steam turbines, or more traditional photovoltaic solar panels. However, recent breakthroughs at MTPV Corp. (which stands for Micron-Gap Thermal Photovoltaics, the name of the technology they’re using) supposedly deliver “an order of magnitude” more power than regular thermal photovoltaics.

mtpv thermal photovoltaics imageWhat’s the difference between conventional solar panel and photovoltaics from thermal photovoltaic systems?

A conventional solar panel absorbs light from the entire spectrum, but it only converts certain colors efficiently. Much of the energy in the other wavelengths of light goes to waste. As a result, the maximum theoretical efficiency of a conventional solar cell is 30 percent, or 41 percent if the sunlight is first concentrated using a mirror or lens. In a thermal photovoltaic system, light is concentrated onto a material to heat it up. The material is selected so that when it gets hot, it emits light at wavelengths that a solar cell can convert efficiently.As a result, the theoretical maximum efficiency of a thermal photovoltaic system is 85 percent.

-Technology Review

Using “micron-gaps” between the heated part and the photovoltaic part (instead of the traditional bigger gaps), they claim to have increased the flow of photons to the solar panel by 10 times compared to traditional TPV technology, which not only makes the whole thing less expensive (coupled with the fact that 1/10 as much solar-cell material as traditional TPV is used), but also lowers its working temperature significantly.

The 85% efficiency theoretical figure mentioned above is of course very hard to reach, but MTPV’s computer models show that 50% efficiency should be possible. So far the company has reached 10 to 15%, which is similar to many other solar panels on the market (not bad). With a bit more progress (it probably hasn’t been getting much R&D effort compared to silicon and thin film solar cells), this technology could become a big player in the solar power world.

Argentina Joins Ban Against Incandescent Lightbulbs

In energy efficiency, green policy on January 20, 2009 at 11:47 pm

Incandescent Light Bulbs Ban Campaign Greenpeace Photo
Picture: Greenpeace Argentina.

In the midst of the end-of-year-holiday-rush the Argentine Senate approved a law to ban incandescent light bulbs. The rule establishes that from December 31, 2010, the importing and commercialization of incandescent light bulbs for residential use will be forbidden in the country.

With this measure, Argentina joins the list of regions and countries that have already said goodbye to regular light bulbs, which includes the European UnionAustralia, and Canada.

The law, which doesn’t have an official number but whose file is 36/08, has five articles:

  1. The first establishes the ban of importing and commercialization of incandescent light bulbs for residential use in all the Argentine territory.
  2. The second gives the Executive Power the ability to establish exceptions to the rule for, “technical, functional and operative reasons.”
  3. The third says that the Executive will be able to announce measures to encourage the imports of finished efficient bulbs or their parts for production.
  4. Finally, the fourth article says the law will enter force when published at the governmental Official Bulletin (the fifth is only operational).

Greenpeace’s local office had pushed this project all 2008 and celebrated the approval of the law. The idea is indeed a great step for Argentina in the face of the country’s deepening energy crisis. However, much remains to be seen about the efficacy of this law; political steadfastness and proper enforcement are just as important factors to success. A negative example would be the woods protection law, which was sanctioned in November 2007 and steady for a year without entering force (heavy interests from the agriculture sectors at stance there).

Changing incandescent light bulbs for CFLs (Compact Fluorescent Lightbulbs) is one of the simplest ways to reduce the amount of energy you spend at home and pay your contribution to the planet.

New Battery Technology Improves MacBook Pro Battery Life by 60%

New battery technology in the 17″ MacBook Pro was shown off at MacWorld today, which lays claim to a battery life improvement of 60%. The new battery can last up to 8 hours on a charge, and can be charged 1,000 times, equivalent to about 5 years. It’s also recyclable at the end of it’s life. But there are even more green features to this new technology.

Apple made a block of batteries, rather than the usual cylindrical cells that end up wasting space. The newly utilized space allows the notebook to have a 40% bigger battery, without making the notebook bigger. The problem, of course, is that you have to take the notebook apart if you want to replace the battery. 

But the upside is that it will last three times longer than the industry standard. The trick for making it last longer is using a chip within the battery that communicates with each cell to make adjustments to the current for each cell. This means a maximized battery life.

With it lasting so much longer, and being recyclable at the end of it’s life, that alone is enough to get Dell to hush up a bit. But additionally, Apple has a take-back program for the batteries, making recycling even easier, and it is EPEAT Gold, arsenic, BFR, mercury, PVC free, and touts 34% smaller packaging.

EU Wants to End Conventional Incandescent Lightbulbs

In environment, global warming, green policy, green politics, green technology on December 28, 2008 at 1:02 pm

Improvements to conventional bulbs reached a limit 50 years ago
A European Union report has recommended banning conventional incandescent light bulbs by 2012 to save energy and cut down on greenhouse gas emissions.

 

Most light bulbs sold in the EU are of the type developed by Thomas Edison in 1879.

But the report says the EU could save up to $12bn (£8bn) a year in energy bills by switching to low-energy bulbs.

The report needs the backing of the European parliament and all 27 member states to become law.

“It’s very clear that this is a measure that will change the way that we consume energy,” EU Energy Commissioner Andris Piebalgs told journalists.

Phase out

Once approved, the EU would phase out conventional bulbs between September 2009 and September 2012.

 

Consumers will choose between long-life fluorescent bulbs or halogen lamps.

The EU says the measure will save households up to 50 euros ($64, £43) a year and pump up to 10bn euros ($13bn) into the economy.

“European homes will keep the same quality of  lighting while saving energy, CO2 and money.” Andrea Piebalgs, EU Energy Commissioner 

The new-style lamps carry energy savings of 25% to 75% compared to traditional incandescent bulbs, which are little changed since they were invented almost 130 years ago.

The report also says the switch will reduce carbon dioxide emissions by 12 million tonnes a year, and save energy equivalent to the consumption of 11 million European households.

Mr Piebalgs said that the phasing out had to be gradual so that “production facilities could adapt to the new lighting” and the quality of illumination could be ensured.

“European homes will keep the same quality of lighting, while saving energy, CO2 and money,” he said.

Several nations including Australia, New Zealand, Canada and the Philippines have already announced they will phase out or restrict sales of traditional bulbs.

ASUS, in addition to getting its N series notebooks ranked EPEAT Gold, has earned the first ever EU Flower Eco Award for computers for that very same notebook series.

While the name is rather, well, flowery, the award is not. It’s a really big deal they achieved it and makes a big green-hued statement to the rest of the computing world.

ASUS has been a quiet leader for some time in environmental sustainability in the computer world. That is recognized by its earning one of the industry’s toughest awards, and being the company that made the world’s first computers to earn it.

With the awarding of EU Flower certification to the N50, N80, N20, and N10 notebooks, ASUS notebooks have secured a spot in history as the world’s first computers to be conferred the prestigious award. Underscoring the magnitude of this achievement is the fact that 15,000,000 computers are sold in Europe each year, and ASUS N Series notebooks are the first to obtain EU Flower certification.

The award criteria includes energy savings, hazardous substances, product design, user instructions, packaging, labeling, noise, lifetime extension, and Takeback programs. A computer has to be all-around green to even rank for the EU Flower award – one of the highest rated and strictest standards for computing in the world.

Go, go Green ASUS!

Incredible Sahara Forest Project to Generate Fresh Water, Solar Power and Crops – A Collaboration between CSP & Seawater Greenhouses

In alternative energy, architecture, environment, solar energy on September 14, 2008 at 12:43 pm

The Sahara Forest Project image

Can you imagine being able to produce enough water in the Sahara to grow crops there? Can you imagine harnessing sufficient quantities of solar power to supply electricity to cities in Africa and cities in Europe? Can you imagine producing a sustainable bio-fuel that doesn’t impact on world food supplies? Charlie Paton,Michael Pawlyn and Bill Watts can and what’s more they can imagine all these happening in the same place at the same time.

This week this trio of visionaries launched the Sahara Forest Project: their proposal to combine two innovative technologies, Concentrated Solar Power (CSP) and Seawater Greenhouses, to produce renewable energy, water and food in an area of desert known to be one of the hottest places on earth.

Multitasking renewable solutions
It has often been said that there will be no one solution to solving the climate crisis and all those issues that surround it, such as energy sources, food prices and water supply. We need a portfolio of technologies to help us to combat these advancing problems. The Sahara Forest Project is one of the first projects we’ve seen that proposes not only to combine technologies to optimise performance and production, but also aims to tackle all of the serious challenges mentioned above. It is a bold and ambitious plan that, if realised, could have a powerful positive impact not only for the Sahara region, but also for Europe and the rest of the world.

Positive Collaboration
The most exciting aspect of the Sahara Forest Project is not specifically the use of these technologies. We’ve read about Seawater Greenhouses and Concentrated Solar Power and how they’re being used to great effect. It is the fact that they are being used together in the same place, to support each other and optimize their operating capacities to produce energy and water and by proxy vegetation.

This sense of collaboration is echoed in the team of people behind the proposal: an inventor – Charlie Paton, creator of the Seawater Greenhouse; an architect – Michael Pawlyn of Exploration Architecture, previously of Grimshaw and the lead architect on the iconic Eden Project; an engineer – Bill Watts of Max Fordham & Partners, an engineering firm that focuses on energy efficient systems for the built environment. These three men have brought their considerable expertise together to create a truly innovative proposal.

Illustration of greenhouses having a similar effect on the climate as a region of forest, yet providing a net input of water vapour from the sea.

What does a Seawater Greenhouse do?
The Seawater Greenhouse was designed to address the problem of irrigating crops in arid coastal regions by evaporating seawater and condensing it into fresh water. This helps to reverse the trend of desertification created by normal industrial greenhouses, which can use up to five times more water to irrigate crops than the respective region’s average annual rainfall. The system works by mimicking the natural hydrological cycle where seawater heated by the sun, evaporates, cools down to form clouds and returns to the earth as rain, fog or dew.

What does Concentrated Solar Power do?
CSP is currently seen as one of the most exciting and powerful ways of harnessing the sun’s energy to create power. Like the Seawater Greenhouse, CSP works well in hot arid areas where the sun is at its most powerful. The sun’s rays, collected through reflecting mirrors, are used to heat water which then produces steam to power turbines. Examples currently working are Nevada Solar 1 near Las Vegas, and the solar tower in Barstow California. It has been proposed that the energy created by CSP in the Sahara could be transported to Europe with minimal loss via high voltage DC power lines.

How will the Sahara Forest Project work?
These CSP / Seawater Greenhouse technologies will work together at a location some distance from the north coast of Africa, hopefully at a point below sea level which will reduce or potentially eliminate the costs of pumping seawater. The scheme has been designed as a ‘hedge’ of greenhouses providing a windbreak and shelter for the outdoor planting. CSP arrays will be placed at intervals along the greenhouse ‘hedge’. The greenhouses produce five time more fresh water than needed for the plants inside. This surplus will be used to irrigate the planted orchards and the Jatrophra crop, which can be turned into bio-fuel for transportation and other needs.

Commercial Synergies
The Sahara Forest Project team tell us that the innovative interaction between the two technologies helps each to function more efficiently:

1.CSP systems need water for cleaning the mirrors and for the generation of steam to drive the turbines which the greenhouses can provide.

2.The Greenhouse evaporators make very efficient dust traps (as do plants that are growing outside) which benefits the CSP since the mirrors stay cleaner and therefore operate more 
efficiently.

3. In solar thermal power plants, only about 25% of the collected solar energy is converted into electricity. If combined with sea water another 50% of the collected energy, normally released as heat, can be used for desalination. This way, up to 85% of the collected solar energy can be used.

In conclusion the Sahara Forest Project works on many levels. By combining the benefits of Concentrated Solar Power and Seawater Greenhouses the design team has vastly scaled up the positive outputs of renewable energy, food production and fresh water supply. Furthermore they tell us that “the scheme would also have the restorative effect of returning areas of desert to forested land and sequestering substantial quantities of atmospheric carbon in new plant growth and reactivated soils.” Surely this is a perfect example of the potential power of human and technological collaboration.

IKEA Puts $U.S. 75 Million Toward Cheap Solar

In architecture, environment, green policy on August 25, 2008 at 10:53 am

IKEA Invests In Green Tech photo

Johan Stenebo is chief of an IKEA susidiary called Greentech, and a man with a dream. Stenebo wants to invest in the “cheapest, best” PV roof panels available in order to sell them in IKEA stores in the next two to four years.

Low-cost solar a tall order
Of course, that’s a very tall order. But IKEA founder Ingvar Kamprad’s son Peter is an avowed green tech believer, and Stenebo’s Greentech will put about US$75 million into at many as ten companies in five different areas: solar technology, energy conservation, water saving products, alternative lighting, and new product materials. Scandinavian companies are Greentech’s first focus. Nearly all of these areas are ones we would welcome the IKEA low-cost approach to, although setting up solar roof panels with just the simplistic diagrams and little Allen keys that accompany IKEA’s usual do-it-yourself furniture seems something of a stretch. Then there’s the problem than many installations require building and other permits. But IKEA’s fabulous distribution network of 270 global superstores would mean green tech for the global masses, a welcome development.

Solar supermarkets in four years?
Up until now, IKEA has held itself to interior decoration rather than pursuing the constructing and building sector that is dominated (at least in the U.S.) by players such as Lowe’s and Home Depot. But these megastores haven’t tried to sell green solutions in any organized fashion, so IKEA sees little current competition for its plans to get products to stores in three to four years.

“Repowering America”, Speech by Al Gore

In environment, green policy on August 11, 2008 at 5:18 pm

At D.A.R. Constitution Hall in Washington D.C., Al Gore delivered a speech which outlines his vision of how the United States needs another ‘moon shot’ to solve the intertwined problems of climate change and energy independence. Though he doesn’t come out and say it, he even alludes to peak oil.

Here are some of choice quotes from Mr Gore’s speech:

Reliance on carbon-fuels the source of the environmental problems we’re facing

Yet when we look at all three of these seemingly intractable challenges at the same time, we can see the common thread running through them, deeply ironic in its simplicity: our dangerous over-reliance on carbon-based fuels is at the core of all three of these challenges – the economic, environmental and national security crises. We’re borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the planet. Every bit of that’s got to change. But if we grab hold of that common thread and pull it hard, all of these complex problems begin to unravel and we will find that we’re holding the answer to all of them right in our hand.

Renewable energy the solution to climate crisis, economic woes, national security

The answer is to end our reliance on carbon-based fuels. In my search for genuinely effective answers to the climate crisis, I have held a series of “solutions summits” with engineers, scientists, and CEOs. In those discussions, one thing has become abundantly clear: when you connect the dots, it turns out that the real solutions to the climate crisis are the very same measures needed to renew our economy and escape the trap of ever-rising energy prices. Moreover, they are also the very same solutions we need to guarantee our national security without having to go to war in the Persian Gulf.

Best way to use renewable energy is for electricity

The quickest, cheapest and best way to start using all this renewable energy is in the production of electricity. In fact, we can start right now using solar power, wind power and geothermal power to make electricity for our homes and businesses. But to make this exciting potential a reality, and truly solve our nation’s problems, we need a new start.

100% renewably generated electricity in 10 years

Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years. This goal is achievable, affordable and transformative. It represents a challenge to all Americans – in every walk of life: to our political leaders, entrepreneurs, innovators, engineers, and to every citizen.

 

National grid infrastructure must be expanded to areas best suited for renewable development

To be sure, reaching the goal of 100 percent renewable and truly clean electricity within 10 years will require us to overcome many obstacles. At present, for example, we do not have a unified national grid that is sufficiently advanced to link the areas where the sun shines and the wind blows to the cities in the East and the West that need the electricity.

 

Carbon tax should replace large part of payroll tax

Of course, we could and should speed up this transition by insisting that the price of carbon-based energy include the costs of the environmental damage it causes. I have long supported a sharp reduction in payroll taxes with the difference made up in CO2 taxes. We should tax what we burn, not what we earn. This is the single most important policy change we can make.

 

U.S. Should rejoin the international community regarding climate change

In order to foster international cooperation, it is also essential that the United States rejoin the global community and lead efforts to secure an international treaty at Copenhagen in December of next year that includes a cap on CO2 emissions and a global partnership that recognizes the necessity of addressing the threats of extreme poverty and disease as part of the world’s agenda for solving the climate crisis.

 

Peak Oil? In all but name.

If you want to know the truth about gasoline prices, here it is: the exploding demand for oil, especially in places like China, is overwhelming the rate of new discoveries by so much that oil prices are almost certain to continue upward over time no matter what the oil companies promise. And politicians cannot bring gasoline prices down in the short term.

 

Obligatory memory of the first ‘moon shot’

On July 16, 1969, the United States of America was finally ready to meet President Kennedy’s challenge of landing Americans on the moon. I will never forget standing beside my father a few miles from the launch site, waiting for the giant Saturn 5 rocket to lift Apollo 11 into the sky. I was a young man, 21 years old, who had graduated from college a month before and was enlisting in the United States Army three weeks later. 


I will never forget the inspiration of those minutes. The power and the vibration of the giant rocket’s engines shook my entire body. As I watched the rocket rise, slowly at first and then with great speed, the sound was deafening. We craned our necks to follow its path until we were looking straight up into the air. And then four days later, I watched along with hundreds of millions of others around the world as Neil Armstrong took one small step to the surface of the moon and changed the history of the human race.

We must now lift our nation to reach another goal that will change history. Our entire civilization depends upon us now embarking on a new journey of exploration and discovery. Our success depends on our willingness as a people to undertake this journey and to complete it within 10 years. Once again, we have an opportunity to take a giant leap for humankind.

Perhaps Bill McKibben, quoted in the We Campaign’s press materials, says it more succinctly that I can, “Finally a response to both the science of climate and the economics of energy on a scale commensurate with the problem. This is a plan that breaks us out of muddling, temporizing stalemate and sets a clear path forward towards an imaginable future.”

Forbes Magazine has produced a special report on a subject dear to our hearts, efficiency, the fifth fuel. Amory Lovins kicks it off with The Case for Efficiency:

“Using smarter technologies, more brains and less money to wring more work from less delivered energy–what energy experts call “end-use efficiency”–is the largest, cheapest, safest, cleanest, fastest, most diverse, least visible, least understood and most neglected way to provide energy services.”

The Train that Stops for No One: Efficiency to the Max

In Uncategorized on July 20, 2008 at 6:32 pm

 

The Train That Never Stops

The above video, demonstrates a rather interesting concept by Taiwanese inventor Peng Yu-Lun for a train that never stops. He correctly points out that trains would be far more efficient (and on-time) if they didn’t have to go through the trouble of, you know, stopping to pick up passengers, Unfortunately, at present not stopping for passengers would mean, well, no passengers. Yu-Lun’s design solves that problem with a kind of “top-mounted boarding shuttle that is scooped up when the train passes one station and automatically deposited when it reaches the next stop.” See the video to get a better sense of how it would work.

Taiwanese inventor Peng Yu-Lun believes that trains are more energy inefficient than they have to be, hobbled ecologically by the totally unnecessary task of having to stop to pick up passengers. To counter the problem, he has invented a concept for a constantly moving train, or a “non-stop MRT system.”
