Friday Green Numbers round-up for Feb 11th 2011

Green Numbers

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

  1. Vice President Biden Announces Six Year Plan to Build National High-Speed Rail Network

    Vice President Joe Biden today announced a comprehensive plan that will help the nation reach President Obama?s goal of giving 80 percent of Americans access to high-speed rail within 25 years, as outlined in his State of the Union address. The proposal will place high-speed rail on equal footing with other surface transportation programs and revitalize America?s domestic rail manufacturing industry by dedicating $53 billion over six years to continue construction of a national high-speed and intercity passenger rail network.

    As a part of President Obama?s commitment to winning the future by rebuilding America?s roadways, railways and runways, the plan will lay a new foundation for the nation?s

  2. Energy and Carbon Software Market Poised for 300% Growth; Sector Leaders Named

    The market for enterprise energy and carbon accounting (EECA) software grew 400 percent during 2010 and is forecast to grow another 300 percent this year, according to research by efficiency system provider Groom Energy Solutions.

    The research found that more than 200 large corporations ? including Arch Coal, Bayer, RJ Reynolds, Safeway and Wyndham Hotels ? bought EECA software in 2010.

    The report names ten companies as EECA leaders for 2011. They are

  3. US diplomat convinced by Saudi expert that reserves of world’s biggest oil exporter have been overstated by nearly 40%

    The US fears that Saudi Arabia, the world’s largest crude oil exporter, may not have enough reserves to prevent oil prices escalating, confidential cables from its embassy in Riyadh show.

    The cables, released by WikiLeaks, urge Washington to take seriously a warning from a senior Saudi government oil executive that the kingdom’s crude oil reserves may have been overstated by as much as 300bn barrels ? nearly 40%.

    The revelation comes as the oil price has soared in recent weeks to more than $100 a barrel on global demand and

  4. Bridgelux Raises $20M For LEDs

    LED chip and array maker Bridgelux raised close to $50 million just a year ago, but is raising even more money, according to a filing. The nine-year-old venture-backed startup which is looking to do for lighting what Silicon Valley has done for communications and entertainment ? make it digital ? has raised $20.74 million of a planned $21 million round.

    The company opened a factory in California and was making an effort to scale up its production last year, so

  5. British windfarms blow Vestas towards 25% profit rise

    Strong demand from British windfarms helped the world’s biggest turbine manufacturer, Vestas, raise profits by 25% over the past year and have boosted future prospects.

    UK equipment deliveries totalled 530MW ? a leap from 120MW over the previous year ? helped in particular by shipments for the 300MW Thanet windfarm, which is currently the largest offshore windfarm ever built.

    Shares in Vestas soared 5% as the Danish-based group reported

  6. Vodafone [Ireland] embarks on green drive to cut paper bills by 70%

    Ireland?s largest mobile operator Vodafone has asked customers to opt to switch to paperless billing as part of its drive to cut down on paper by 70%. The move, it says, will be equal to saving 5,000 trees and 500 tonnes of CO2.

    The company today launched its paperless billing campaign ?Goodbye Paper Bills, Hello Trees? and calls on Vodafone customers to make the switch to paperless billing.

  7. EMC? Cork plant cuts energy use by 20% after ?radical? retrofit

    EMC?, which employs 1,650 people at its Ovens site, undertook a full retrofit project to implement energy saving technologies at the information technology and data centre site, using free cooling technology systems.

    The ?2.5 million project, which was designed and managed by consulting engineering company Arup, will achieve annual electricity savings of 13 million kilowatt hours and an annual carbon emission reduction of 7,000 tonnes.

  8. Hopes of 30% cut in greenhouse emissions dashed

    The UK government’s plan to push Europe to deeper cuts on greenhouse gas emissions has been dashed by the EU’s energy chief.

    G?nther Oettinger, the EU’s energy commissioner, dealt a heavy blow to the hopes of several member states that have been pressing for a target of slashing emissions by 30% by 2020, against the current 20%.

    He said the tougher target would force industries to ….

  9. China bids to ease drought with $1bn emergency water aid

    China has announced a billion dollars in emergency water aid to ease its most severe drought in 60 years, as the United Nations warned of a threat to the harvest of the world’s biggest wheat producer.

    Beijing has also promised to use its grain reserves to reduce the pressure on global food prices, which have surged in the past year to record highs due to the floods in Australia and a protracted dry spell in Russia.

    The desperate measures were evident at

  10. Obama Admin: 1M Electric Vehicles by 2015 Still On Course

    President Obama?s plan to put 1 million electric vehicles on the road by 2015 was reaffirmed on Tuesday.

    A new report issued by the Department of Energy outlines a strategy for achieving that goal, which Obama announced in his State of the Union address last month. David Sandalow, the Energy Department?s Assistant Secretary for Policy and International Affairs, said the goal can be reached if the proper steps are taken.

    ?To succeed in meeting the President?s goal, we?ll need …

  11. Ocean energy could create 70,000 jobs [in Ireland] ? Bord G?is

    Bord G?is have claimed that the ocean energy industry could create up to 70,000 jobs and be worth ?120bn to the Irish economy.

    In a speech to the Ocean Energy Industry Forum 2011 today, Bord G?is CEO John Mullins outlined his concern that ?not enough investment and planning is being put into developing Ireland?s ocean energy resources,? however.

Spain gets 53% of its energy from wind!

Record Spanish Wind Energy

Ok, not all the time, but last weekend at 5:50am on Sunday morning (8th Nov) Spain set a new record, hitting 53.7% of its energy requirements being supplied by wind energy.

As you can see from the graph above, the amount of electricity being supplied by wind, the light green portion of the graph, doesn’t go below 30% at any point in the 24 hours and is closer to between 40-50% for most of the time!

These are figures the world’s most ambitious countries are targeting hitting by 2020, at the earliest!

Notice also on the graph that the contribution from coal (the red band) during this period is in the low single digits, never rising above 6.4%.

And finally notice also that for a lot of the period significant amounts of generation is below the 0MW line – this occurs when the electricity is being either stored using pumped hydro storage, or being exported for sale on the international markets.

The Guardian reporting on this quoted Jos? Donoso, head of the Spanish Wind Energy Association

“We think that we can keep growing and go from the present 17GW megawatts to reach 40GW in 2020,” he told El Pa??s newspaper.

Windfarms have this month outperformed other forms of electricity generation in Spain, beating gas into second place and producing 80% more than the country’s nuclear plants.

Experts estimate that by the end of the year, Spain will have provided a quarter of its energy needs with renewables, with wind leading the way, followed by hydroelectric power and solar energy.

The graph above is taken from the site of the Spanish grid operator Red Electrica de Espa?a (REE).

The REE website has highly detailed and extremely interactive infographics produced using Adobe’s Flex software:

REALLY Smart Meters!

Smart meter

Smart electricity meter projects are being rolled out all over the globe at this stage (here’s a map of the Smart Meter projects in the US), and with the Smart Meters, come Smart Grids and Demand Response programs whereby the utilities implement peak shaving programs (and in certain cases demand stimulation) to match demand and supply curves. This will lead to a more stable grid and therefore increase the amount of variable generators (i.e. weather based renewables) it is possible to add to the grid. Great.

However, this is not nearly ambitious enough as far as I am concerned. First off, as I have said previously, cheaper electricity typically has a higher % of renewables in the generation mix. Therefore, if I am getting a smart meter, I want it to be a very smart meter. I want my meter to be going out across the grid, checking the realtime price from all utilities and dynamically sourcing the energy from the cheapest supplier at any given time. Nothing too new there, I have written about that concept previously.

Taking that idea to the next level. Imagine if utilities were mandated to publish, not only the price of electricity in realtime, but also the generation mix. I could then have a Smart Meter which would actively chose the greenest electricity for me at any time. Or the one with the best price/renewables mix.

And if we had a SuperGrid in place, then that Green electricity might be coming from Danish windfarms, Icelandic geothermal generation or North African solar farms.

Now that would be a Really Smart Meter!

UPDATE – I have been asked the relevance of the photo above – it is subtle, anyone care to guess?

New, radically more efficient wind turbines

Traditional wind farm

The traditional look of windfarms, like the one above, could be changing if an article I read on News.com recently is anything to go by. The piece was about a new type of wind turbine from a company called FloDesign.

The devices have:

  • -shorter sturdier rotors so the turbines can be placed closer together. This also vastly eases the problems associated with transporting normal blades
  • -smaller blades which also means that the turbines can continue operating at higher wind speeds long after existing wind turbines would have to shut down
  • -a fin which points it into the wind, negating the need for a motor to turn it and thus making it easier to maintain and more efficient and
  • -a cowled prop, not unlike jet engines, which generates vortices. These vortices magnify the energy from the wind allowing them to capture 3-4 times more energy than traditional wind turbines.

Small wonder then that they have been winning prizes all over the place and, according to the News.com article, attracting the attention of pre-eminent VC firm Kleiner Perkins Caufield & Byers.
