Category: Energy Matters

The twentieth century way of life has been made available, largely due to the miracle of cheap energy. The price of energy has been at record lows for the past century and a half.As oil becomes increasingly scarce, it is becoming obvious to everyone, that the rapid economic and industrial growth we have enjoyed for that time is not sustainable.Now, the hunt is on. For renewable sources of energy, for alternative sources of energy, for a way of life that is less dependent on cheap energy.

    Gilbert school ‘green’ in more ways than 1

    Although the Campo Verde High School name was not chosen for the “green” elements found throughout the Gilbert campus, it’s even more fitting that the school has green in its name because of all the energy-saving details.


    Former Gilbert Unified School District governing board member Elaine Morrison said she chose Campo Verde, which means “green field” in Spanish, because of the area’s farming and cultural history.


    When freshmen and sophomores start at their new school on Aug. 10, they’ll walk under green, patina-coated metal walkways throughout the campus, which provides shade for them and keeps the buildings cooler, said Dave Tucker, the project manager with CORE Construction, the company building the school. CORE is a member of the United States Green Building Council.



     


    The exterior windows have 1-inch-thick, insulated glass, and those not shaded by the walkways have green, patina-coated aluminum shades, which reduces cooling and heating costs. The windows also have interior window blinds, and students will notice more windows in their classroom to let in more natural light.


    As students walk into their new classrooms, the motion-detector lights will turn on; when they leave, the lights will turn off.


    A campuswide lighting control system will give school staff an opportunity to easily turn off various lights around campus to reduce energy costs, Tucker said.


    Gilbert governing board member Helen Hollands said she is “thrilled” the board chose to put “green” elements into the district’s fifth and final high school on the northwest corner of Germann Road and Quartz Street, just west of Val Vista Drive off the Santan Freeway stretch of Loop 202.


    Hollands was board president in February 2008 when the board approved the $1.4 million in “green” elements.


    The school cost about $52.8 million to build, with an additional $4.7 million for nearby road improvements.


    “I think it’s important that we are conscious protectors of our environment,” Hollands said. “Personally, I wish we could have gone further, but we have to balance it with the money we have available.”


    The green grass on the football field is made of synthetic turf, which requires little maintenance. There’s no need for fertilizer, mowing, and repainting the lines on the field since the yard markers are actually sewn into the turf, Tucker said.


    Water is only used to cool and clean off the $500,000 field, which is another savings. Eight water cannons on the perimeter of the field can spray water onto the field to cool it off for the Campo Verde Coyotes, the school’s mascot.


    The turf will last 15 years, Tucker said, and sits next to the six baseball and softball fields, six tennis courts and three basketball courts.


    “It certainly is an absolutely beautiful facility, and I understand from a maintenance standpoint we will realize quite a bit of savings,” Hollands said. “Yes, from a capital standpoint it’s more expensive, but long term we don’t have those maintenance and operations expenses.”


    Besides the “green” aspects of the turf, since the field is not real grass, it can be used year-round for practice, band and soccer, and even after rain, without tearing up the field. This also eliminated the need for two practice fields, Tucker said.


    Students eating outside under the dining canopy will be cooled by solar-powered fans.


    “I like that the students will be able to see it in action,” Hollands said.


    Desert landscaping replaced several lawn areas throughout the campus, although there is still lots of green grass for the students.


    A “state of the art” central air conditioning plant is in a large room in back of the cafeteria and is the “most energy efficient” to cool the campus, Tucker said.


    The fields and landscape are irrigated with nonpotable water, and faculty bathrooms have two-stage flushing.


    Students will also have a “very cutting-edge technology” educational tool with the opportunity to see the electrical consumption the school is using by accessing a Web site, Tucker said.


    A 400-kilowatt solar panel array could also be placed on top of the cafeteria and an adjacent classroom building to tie into the power grid and save even more money for the school. The school board is still considering the extra costs for the solar panels.


    “This is the first high school we’re (CORE Construction) building with synthetic turf and sonar panels,” Tucker said. “As the technology improves and items become more affordable, ‘green’ elements will become more common.”


    The 60-acre, 250,000-square-foot school also has an amphitheater with seating capacity for 725 people, a main gym with three basketball and three volleyball courts, and a practice gym with an additional basketball and volleyball court.


    The school also has a dance room with mirrors covering three walls of the room, a weight room next door, and several rooms for orchestra, band and choir.


    To continue the greenness of the school, students chose copper and dark green as the school colors.

    Perhaps propelled by the recent dawn of solar powered airplanes, this stunning solar powered blimp is poised to take flight by harnessing sunlight for fuel. Dubbed Nephelios, the solar-powered helium blimp was designed and built by high school engineering students in France. The history making blimp will begin test flights in the next 2 weeks, and by summer’s end the designers hope to fly Nephelios across the English Channel, “just to show that it’s possible.” Nephelios will be the first manned solar airship in existence, and its inaugural flight will prove that CO2-free air travel is now a reality.
    Part of the Sol’R Project, Nephelios consists of a lightweight aluminum frame with an outer wrap of nylon and polyethylene, which is filled with helium (He, atomic #2, and a noble gas, just in case you forgot). Stretched out on top of the blimp are flexible solar panels that collect energy from the sun and convert it to power a small motor, which turns two large red propellers. The solar panels are capable of generating 2.4 kW of power and provide enough energy to propel the 18 foot in diameter blimp at 25 mph.


    In June, Nephelios debuted at the French Air Show in Le Bourget, where it was well received and commended for resurrecting the airship. As previously mentioned, within the next two weeks, the student group will be testing the blimp for the first time, and by the end of the summer the students hope to fly it across the English Channel at the Strait of Dover, which is the shortest span of ocean between the two continents. They expect the flight to take a little less than an hour. When they succeed, this will be the first flight of a solar powered airship, and we eagerly await the landing of Nephelios in the UK.

  • World Bank Outlines Priorities for Sustainable Hydro Development

    World Bank Outlines Priorities for Sustainable Hydro Development


    by John Braden, Senior Associate Editor, Hydro Group

    Washington, D.C. United States [RenewableEnergyWorld.com]

    Acknowledging a sharp change in direction from the 1990s, the World Bank is emphasizing a growing role for sustainable hydropower to bring both energy and water resources benefits to the developing world.


    The World Bank report said total economically feasible potential hydro capacity in developing countries exceeds 1,900,000 MW, 70 percent of which, 1,330,000 MW, is not exploited.



    In “Directions in Hydropower,” a newly issued exposition of the World Bank Group’s views on the value of hydropower, the bank said hydropower now is viewed as an integral factor in addressing energy security, climate change, water security and regional cooperation.





    World Bank lending for hydropower bottomed out in 1999 due to growing opposition from environmental and other non-governmental organizations.

    “There are risks inherent in development and operation of hydropower, many of which were the focus of passionate debate in the 1990s,” the bank said. “These risks cross the range of financial, geological, engineering and market concerns, with particular attention to environmental protection, resettlement, social inclusion and sharing of the benefits of development across all stakeholders.”

    Triple Bottom-line Policy: Social, Environmental, Economic

    As a consequence, the bank said, the definition of acceptable hydropower has shifted to one that recognizes core principles of sustainable development with attention to social and environmental, as well as economic “bottom lines.” It said the shift has been supported by a decade of better understanding and of developing best practices, safeguards and self-assessment measures from players including the World Bank, Equator Banks, International Hydropower Association, International Energy Agency, the World Commission on Dams and the United Nations Environment Program.

    “The priority is shifting towards development ‘done right’ and comprehensive environmental management and benefits sharing,” the bank said.

    In a stark change from a decade ago, World Bank lending now reflects a Water Resources Sector Strategy approved in 2003 that says significant levels of investment in water infrastructure are required throughout the developing world.

    New lending for hydropower increased significantly, from less than US $250 million per year from 2002-2004, to US $500 million per year from 2005-2007. In fiscal year 2008, new lending for hydro exceeded US $1 billion.

    The bank said 67 hydropower projects have been approved since fiscal year 2003, amounting to US $3.7 billion in World Bank Group contributions to support a total of US $8.5 billion and nearly 9,700 MW in project investments. Within those numbers, the bank noted, is money for rehabilitation of existing capacity at the 350-MW Inga 1 and 1,424-MW Inga 2 hydro projects in the Democratic Republic of Congo (HydroWorld 4/20/09) and of hydro plants totaling 1,338 MW in Niger. (HydroWorld 2/11/09)

    Bank Sees Pipeline of US $2 Billion in Projects

    Major hydro projects have been approved in Africa and Asia, as well as several rehabilitation projects in Eastern Europe. The bank said a range of new projects is under discussion in India, Vietnam, the Nile Equatorial Lakes Region, Ethiopia, Guinea, Brazil, Romania, Turkey, Georgia and Tajikistan. Bank-backed carbon finance projects are under discussion in Russia, Sri Lanka and Madagascar.

    The bank’s two-track strategy of investment lending, and energy and water sector strengthening, has only just begun. The bank said it has identified a “promising pipeline” of US $2 billion in projects under preparation for the next several years, not including projects that are only under preliminary discussion with clients.

    The World Bank report said total economically feasible potential hydro capacity in developing countries exceeds 1,900,000 MW, 70 percent of which, 1,330,000 MW, is not exploited. That is four times the current installed hydro capacity of Europe and North America and nearly double the 740,000 MW installed worldwide. It said significant additional amounts of energy and capacity are available from rehabilitation of existing hydropower and water resources assets.

  • Ooops. The nuclear ‘ solution’ just melted down

    Ooops. The nuclear ’solution’ just melted down.




    For all those who suggest that nuclear power is the only solution to climate change, there’s a little spanner in the works – nukes don’t deal with the heat…


    The Times of London is reporting that:



    France is being forced to import electricity from Britain to cope with a summer heatwave that has helped to put a third of its nuclear power stations out of action.


    As temperatures in France head up over 30C (not hot for us, sure, but it is for them!), the cooling water gets too hot and the plants need to be ramped way down or even shut down to avoid breaching safe operational temperatures. Coinciding with increased demand for electricity in hotter weather, this ain’t good news for the world’s only power sector heavily reliant on nukes.



     


    This isn’t the first time this has happened. But, as Paris sizzles in the summer more frequently, it is happening more often. And the trend is only due to increase.


    On the other hand, some forms of renewables do well in a climate changing world. Solar thermal obviously will be helped by greater heat, and wind and ocean power will benefit from greater turbulence in both systems. Geothermal won’t be impacted at all. Only bioenergy, the least attractive renewable source to many anyway, stands to be negatively impacted by climate scenarios.


    This is, of course, only one more reason on top of several others why nuclear is no solution. The massive cost blowouts in every nuclear development for decades is one, the very long lead times is another, and the intractable waste issue – linked to nuclear weapons proliferation – is the most critical. But heat shutting down existing plant is a killer from a base PR point of view ;-)


    As they say, if you can’t stand the heat, get out of the kitchen.

  • BP shuts alternative energy HQ

    BP shuts alternative energy HQ


    • ‘Beyond Petroleum’ boast in doubt as clean energy boss quits
    • Renewables budget will be reduced by up to £550m this year

    BP has shut down its alternative energy headquarters in London, accepted the resignation of its clean energy boss and imposed budget cuts in moves likely to be seen by environmental critics as further signs of the oil group moving “back to petroleum”.



     


    But Tony Hayward, the group’s chief executive, said BP remained as committed as ever to exploring new energy sources and the non-oil division would benefit from the extra focus of being brought back in house.


    BP Alternative Energy was given its own headquarters in County Hall opposite the Houses of Parliament two years ago and its managing director, Vivienne Cox, oversaw a small division of 80 staff concentrating on wind and solar power.


    But the 49-year-old Cox – BP’s most senior female executive, who previously ran renewables as part of a larger gas and power division now dismantled by Hayward – is standing down tomorrow.


    This comes alongside huge cuts in the alternative energy budget – from $1.4bn (£850m) last year to between $500m and $1bn this year, although spending is still roughly in line with original plans to invest $8bn by 2015.


    The move back to BP’s corporate headquarters at St James’s Square in London’s West End made sense, particularly when the group was sitting on spare office space due to earlier cutbacks, said Hayward.


    “We are going through a major restructuring and bringing the alternative energy business headquarters into the head office seems a good idea to me.


    “It saves money and brings it closer to home … you could almost see it as a reinforcement [of our commitment to the business],” he said.


    Cox was stepping down to spend more time with her children, Hayward added. “I know you would love to make a story out of all this,” he said, “but it’s quite hard work.”


    The reason for the departure of Cox is variously said by industry insiders to be caused by frustration over the business being downgraded in importance or because she really does intend to stay at home more with her young children. Cox had already reduced her working week down to three days and had publicly admitted the difficulty of combining different roles.


    She will be replaced by another woman, her former deputy Katrina Landis, but the moves will worry those campaigning for more women in business, especially as Linda Cook, Shell’s most senior female executive, has recently left her job too.


    BP has gradually given up on plans to enter the UK wind industry and concentrated all its turbine activities on the US, where it can win tax breaks and get cheaper and easier access to land.


    In April the company closed a range of solar power manufacturing plants in Spain and the US with the loss of 620 jobs and Hayward has publicly questioned whether solar would ever become competitive with fossil fuels, something that goes against the current thinking inside the renewables sector.


    Hayward has also moved BP into more controversial oil areas, such as Canada’s tar sands, creating an impression that he has given up on the objectives of his predecessor, Lord Browne, to take the company “Beyond Petroleum”.

  • A plea to President Obama-end mountaintop mining

     

    Recently, the administration unveiled its new position on mountaintop coal mining and set out a number of new restrictions on the practice in six Appalachian states. These new rules will require tougher environmental review before blowing up mountains. But it’s a minimal step.

    The Obama administration is being forced into a political compromise. It has sacrificed a strong position on mountaintop removal in order to ensure the support of coal-state legislators for a climate bill. The political pressures are very real. But this is an approach to coal that defeats the purpose of the administration’s larger efforts to fight climate change, a sad political bargain that will never get us the change we need on mountaintop removal, coal or the climate. Coal is the linchpin in mitigating global warming, and it’s senseless to allow cheap mountaintop-removal coal while the administration is simultaneously seeking policies to boost renewable energy.

    Mountaintop removal, which provides a mere 7 percent of the nation’s coal, is done by clear-cutting forests, blowing the tops off of mountains, and then dumping the debris into streambeds — an undeniably catastrophic way of mining. This technique has buried more than 800 miles of Appalachian streams in mining debris and by 2012 will have serious damaged or destroyed an area larger than Delaware. Mountaintop removal also poisons water supplies and pollutes the air with coal and rock dust. Coal ash piles are so toxic and unstable that the Department of Homeland Security has declared that the location of the nation’s 44 most hazardous coal ash sites must be kept secret. They fear terrorists will find ways to spill the toxic substances. But storms and heavy rain can do the same. A recent collapse in Tennessee released 100 times more hazardous material than the Exxon-Valdez oil spill.

    If the Obama administration is unwilling or unable to stop the massive environmental destruction of historic mountain ranges and essential drinking water for a relatively tiny amount of coal, can we honestly believe they will be able to phase out coal emissions at the level necessary to stop climate change? The issue of mountaintop removal is so important that I and others concerned about this problem will engage in an act of civil disobedience on June 23 at a mountaintop removal site in Coal River Valley, West Virginia. [Editor’s note: Hansen and 30 other protesters were arrested at the June 23 protest and charged with impeding traffic outside a Massey Energy coal site in Raleigh County, West Virginia.]

    Experts agree that energy efficiency and carbon-free energies can satisfy our energy needs. Coal left in the ground is useful. It holds up the mountains, which, left intact, are an ideal site for wind energy. In contrast, mountaintop removal and strip mining of coal is a shameful abomination. Mining jobs have shrunk to a small fraction of past levels. With clean energy, there could be far more, green-energy jobs, and the government could support the retraining of miners, to a brighter, cleaner future.

    Politicians may have to make concessions on what is right for what is winnable. But as a scientist and a citizen, I believe the right course is very clear: The climate crisis demands a moratorium on new coal-fired power plants that do not capture and safely dispose of all emissions. And mountaintop removal, providing only a small fraction of our energy, should be permanently prohibited.

    President Obama remains the best hope, perhaps the only hope, for real change. If the president uses his influence, his eloquence, and his bully pulpit, he could be the agent of real change. But he does need our help to overcome the political realities of compromise.

    We must make clear to Congress, to the EPA, and to the Obama administration that we the people want mountaintop removal abolished and we want a move toward a rapid phase-out of coal emissions now. The time for half measures and caving in to polluting industries is over. It is time for citizens to demand — yes, we can.
