Bangladesh is going for solar energy in a big way

Why Green Jobs Are Booming in Bangladesh, AN ATLANTIC SPECIAL REPORT The impoverished nation is going solar in a big way.  MAY 12 2014 according to a report released Sunday, the South Asian nation has become a top hot spot for renewable energy jobs, creating a green workforce as large as Spain’s in 2013.

How? Solar energy.

Bangladeshi’s are installing small photovoltaic systems at a rate of 80,000 a month, says the report from the International Renewable Energy Agency (IRENA). In a country where only 47 percent of the population had access to electricity in 2009, according to the Asian Development Bank, solar is increasingly becoming a way to leapfrog the need to build a bigger power grid. In the past 10 years, the number of solar systems in Bangladesh has jumped from 25,000 to 2.8 million, according to IRENA. That in turn has created some 114,000 jobs, from assembling solar panels to selling, installing and maintaining them. In fact, the number of solar-related jobs nearly doubled between 2011 and 2013. “The numbers are set to increase further,” wrote the report’s authors. (By comparison some 4 million people work in Bangladesh’s garment industry.)

Solar energy accounted for 2.3 million of the world’s 6.5 million renewable energy-related jobs in 2013, according to the report. About 70 percent of those solar positions were in China, the biggest green-job generator with 2.6 million people employed in renewable energy overall…….http://www.theatlantic.com/technology/archive/2014/05/why-a-green-jobs-boom-is-under-way-in-bangladesh/362087/

Conservative financier stresses energy security importance of renewable energy

flag-UKGuy Hands: Ukraine crisis underlines importance of UK renewable energy http://www.theguardian.com/environment/2014/may/12/guy-hands-calls-for-government-action-on-renewable-energy

City financier calls on government not to ignore energy security after instability in eastern Europe     The Guardian, Monday 12 May 2014 

WIND-FARMGuy Hands, one of the City’s most flamboyant deal-makers, warns on Monday that the Ukraine crisis has underlined the importance of the UK’s renewable energy sector, and attacks those wanting to phase out onshore wind subsidies.

The financier, who has close links to the Conservative party, says energy security cannot be achieved by markets alone and that the government needs to play a decisive role. “We should be grateful to President Putin for bringing energy security back to the top of the political agenda inEurope. But it is up to us to ensure we understand and act on the long-term threat. And that is certainly not by turning our backs on renewable energy, no matter how persistent or loud the voices against it,” Hands argues in an article on the Guardian website.

The intervention by Hands, who runs the Terra Firma private equity firm, comes at a time when instability in Crimea has been used as a major argument in favour of shale gas – most notably by a House of Lords committee last week.

Hands, whose best man at his wedding was the foreign secretary, William Hague, expresses astonishment that there has been speculation the Tory election manifesto could contain a commitment to end financial help for onshore wind, given it is the “most affordable” of all green power technologies.

Hands’s Terra Firma invests in onshore wind but also landfill gas and other green schemes through a business called Infinis. The financier said Vladimir Putin’s actions in Crimea had done Britain an indirect favour by putting energy security at the top of the agenda. “We have a large industry of successful and enterprising renewable energy businesses which are ready to rise to the challenge of powering homes and businesses from clean and sustainable sources. But politicians are being pressed by a coalition of opponents of renewable energy to ignore this potential.”

He argues that the subsidy debate has been dominated by those who believe energy is a market like any other, and that all efforts should be focused on prices.

“This is nonsense. Energy is not just another commodity but the lifeblood of an economy. No responsible government can step away from a market which is at the heart of a nation’s security and prosperity. Security of supply as well as affordability are  critical. So too are environmental impact and public acceptance.”

Solar panels are back on the White House

Flag-USAWhite House solar panels power up Barack Obama unveils new solar expansion plans as officials confirm White House panels are now operational http://www.theguardian.com/environment/2014/may/09/obama-solar-power-initiatives-california  Suzanne Goldenberg, US environment correspondent  theguardian.com, Friday 9 May 2014 Barack Obama will on Friday unveil several new initiatives intended to expand the deployment of solar power on Friday, as officials confirmed that a set of solar panels on the roof of the White House was now operational.

Obama will – once again – bypass a deadlocked Congress and use his executive authority to announce $2bn funding for energy-saving measures at federal government buildings, as well as new financing and training programmes for solar installations.

The announcements, to be made on a trip to California, cap a climate-focused week at the White House, following the release of an authoritative report on the growing threat posed by heat waves, severe downpours and sea-level rise.

Inside the White House: Solar Panels

White House officials told a conference call with reporters the initiatives were intended to add momentum to the solar industry, which has seen rapid expansion over the last two years.

“We are going to be doing everything we can, with the tools that we have to move forward,” said Dan Utech, special assistant to the president on energy and climate change.

In a largely symbolic move, the White House began installing a small set of solar panels on the roof last summer. The fit was now complete, officials said, releasing a video in which the panels were shown being installed. “The size of the array we established here is the typical size for the average American house, ” said James Doherty, the White House usher. Security concerns had prevented the whole roof being covered, he said.

Obama launches renewable energy actions, aided by corporations

Obama-and-windWith corporate help, Obama announces actions on renewable energy http://af.reuters.com/article/energyOilNews/idAFL2N0NU2OG20140509 WASHINGTON May 9 (Reuters) – President Barack Obama on Friday will announce executive orders to increase the use of solar panels, boost energy efficiency in federal buildings and train more people to work in the renewable energy field, the White House said.

The president, who will make the announcement during a visit to Wal-Mart in Mountain View, California, will also highlight commitments by corporations to lift solar generation at their facilities. Wal-Mart, Apple Inc, Yahoo Inc, Google Inc and Ikea were among the companies making such commitments.

Several financial institutions, including Citigroup Inc and Goldman Sachs Group Inc, were announcing new plans for “large scale investment and innovative programs” to develop solar and renewable energy installations, the White House said.

Obama’s executive actions would support efforts at community colleges so that 50,000 workers would join the solar industry by 2020, it said.

Another initiative would press for $2 billion in energy efficiency upgrades for federal buildings over the next three years, building on another $2 billion commitment from 2011.

Actions to strengthen building codes were also part of the mix. “Investing in solar and efficiency makes sense to reduce our carbon emissions, but also for our pocketbooks and for our economy,” said Dan Utech, an energy adviser to Obama, during a conference call on Thursday to preview Obama’s announcement.

He said the U.S. solar energy industry had expanded dramatically under Obama’s watch, with installations increasing to an amount enough to power more than 2 million homes.

“So momentum is increasing,” Utech said. “Since President Obama took office we’ve increased production from U.S. solar electricity more than tenfold, and in the last year, U.S. production of electricity from solar energy was double what it was just two years ago.”

An Obama spokesman also announced the completion of a project to install solar panels at the White House itself. The panels were American-made and part of an energy “retrofit” for the building that would improve its energy efficiency.

 

“The project, which helps demonstrate that historic buildings can incorporate solar energy and energy efficiency upgrades, is estimated to pay for itself in energy savings over the next eight years,” spokesman Matt Lehrich said. (Reporting by Jeff Mason; Editing by Cynthia Osterman)

Renewable energy can bring Europe’s nations together in co-operation

flag-EUBalance of power: a renewed case for renewable energy for Europe EurActiv 9 May 14, Reinier de Graaf argues that in the midst of the Ukrainian crisis and the energy risks looming over Europe, EU member states should look more seriously into the Roadmap 2050 project initiated in 2009, and aim at cutting Europe’s greenhouse gas emissions by 80% by 2050 through renewable energy use.

Reinier de Graaf directs the work of AMO, the research and design studio established as a counterpart to the architectural practice of OMA. He has been responsible for AMO’s increasing involvement in sustainability and energy planning, which has included Zeekracht: a strategic Masterplan for the North Sea, the publication in 2010 of “Roadmap 2050: A Practical Guide to a Prosperous, Low-Carbon Europe” with the European Climate Foundation, and “The Energy Report,” a global plan for 100 percent renewable energy by 2050, made with the WWF……….

The introduction of a European Supergrid would thus create a situation of mutual complementarity between both Europe’s energy sources and its individual nations. This would help overcome a major disadvantage of renewable energy: the volatility of supply of its individual sources (wind, sun, tidal, etc…) in the face of constant demand. The possibility to draw from multiple sources would create a robust system where the surplus of one source could immediately be used to mitigate the shortfall of another. A system of permanent back-up between nations would ensure constant energy supply for all. (When there is no wind in the north, there is fair chance that there is sun in the south, and vice versa.) A conservative estimate of the amount of terawatt-hours that could be derived from such a system – relying exclusively on existing technology and assuming no major technological breakthroughs – indicates an energy capacity that would surpass that of the entire oil and gas reserves of the Middle East.

Although little more than a footnote at the time, there was another important aspect to the project: Europe could become self-sufficient in its energy supply. Tied to this is an interesting political trade off: independence from external energy providers in exchange for increased energy interdependence between EU member states. Strangely enough, the byproduct of this essentially technical exercise turned out to be a more compelling case for European integration than any which had ever been made in the political arena. ……..

At the time of its launch in 2010, Roadmap 2050 was primarily driven by technological and environmental parameters; today, it is first and foremost the political aspect that grants the project a renewed momentum. Roadmap 2050 could provide Europe the necessary energy security, so it can remain firm about its democratic principles. Energy is primarily exchanged between European states that have committed to the same values and the dependence on outsiders is drastically reduced. The beauty of the idea lies in that within the proposed system no single European state can ever claim a monopoly on energy provision. Energy is exchanged for energy; todays suppliers are tomorrow’s recipients. Dependencies shift, simply on the basis of seasonal or meteorological conditions. The very strength of the project resides in the fact that it ultimately does not assume energy is ever un-political and the profound knowledge that a Europe that relies on energy provided by those who do not share its principles may ultimately well be a Europe unable to afford those principles.  http://www.euractiv.com/sections/energy/balance-power-renewed-case-renewable-energy-europe-302030

Agua Caliente, Florida – the first of many big solar power arrays

World’s Largest Solar Array Set to Crank Out 290 Megawatts of Sunshine Power     Megaplants like Agua Caliente in Arizona herald a new efficiency in solar-sourced electricity Megaplants like Agua Caliente in Arizona herald a new efficiency in solar-sourced electricity Scientific American May 9, 2014 |By Roni Jacobson 

 Global climate change is here, and it’s only going to get worse, according to a White House report released on Tuesday. To combat rising sea levels and blistering summers, the Obama administration has been pushing for clean, renewable energy sources that cut down on carbon emissions. Now one of its projects is poised to pan out: Agua Caliente, the largest photovoltaic solar power facility in the world, was completed last week in Arizona.
 
The plant comprises more than five million solar panels that span the equivalent of two Central Parks in the desert between Yuma and Phoenix. It generates 290 megawatts of power—enough electricity to fuel 230,000 homes in neighboring California at peak capacity. The Agua Caliente Solar Project represents a significant advance in the technology compared with just four years ago, when the largest solar facility in the U.S. generated only 20 megawatts. “Solar has completely arrived as a competitive energy resource,” says Peter Davidson, executive director of the Loan Programs Office at the U.S. Department of Energy (DoE).

Agua-Caliente-solar-project


 
The project, which cost a total of $1.8 billion to construct, received a million-dollar loan from the Loan Programs Office. Under its “SunShot” initiative (so-named in the spirit of president John F. Kennedy’s “moon shot” program), the DoE provides guaranteed loans to unproved ventures in solar power in the hopes of promoting innovation and making the technology more cost-effective.* Although Agua Caliente (owned by U.S. energy giant NRG Energy and partner MidAmerican Solar) is now the largest photovoltaic solar facility in the world, it probably will not hold that distinction for long. …….

Consumers won’t notice much of a difference right away, as utility companies typically draw from a wide array of energy sources, DoE’s Davidson says. “Its like pouring water into a pool: It all gets blended in and then patched out.”
 
But as solar power becomes cheaper, Davidson predicts that utilities will pass those savings on to consumers. And as the technological advancements emerging from megaplants like Agua Caliente become more widely available, individual solar power adopters may eventually see savings as well. http://www.scientificamerican.com/article/world-s-largest-solar-array-set-to-crank-out-290-megawatts-of-sunshine-power/

Africa’s powerful future with renewable energy

logo-IRENARenewable energy will power Africa’s ambitious future Adnan Amin May 3, 2014  It’s time to prove wrong the widely held stereotype about renewable energy only being for rich countries.

As a native of Kenya, I am fortunate to have personal experience of how renewable energy can transform a country that is developing fast. Energy sources in Kenya have diversified since 2000, when renewable power capacity contributed 5.4 per cent of the country’s total energy mix. By 2012, this figure had grown to 16.2 per cent.

With smart planning and prudent investment, all African countries can reduce their dependence on fossil fuels and leapfrog into a sustainable future. And, as Africa makes the transition to renewable energy in the coming years, new projects will provide much-needed jobs and power economic growth………Irena’s initiative encourages the deployment of hydro, geothermal, biomass, wind and solar options from Cairo to Cape Town to increase capacity, stabilise the grid, and reduce fossil fuel dependency. It is a regional approach, promoting international cooperation across countries of the eastern and southern African power pools to develop vast energy resources, optimise the energy mix and attract more investment. The plan identifies development zones to cluster renewable plants in areas with high potential, resource planning, new financing models and knowledge and capacity building.

This week, as we convene for the Abu Dhabi Ascent, we are welcoming many African ministers who have engaged with us on this project.

The Africa Clean Energy Corridor is one of the many concrete steps needed that offer a cost-effective, economically viable solution to the climate challenge that lies ahead of us.

With the right combination of policy, investment and rapid deployment, we can make substantial progress in decarbonising the world’s energy mix while generating growth and employment. http://www.thenational.ae/thenationalconversation/comment/renewable-energy-will-power-africas-ambitious-future#ixzz30tYRkXQl

Island goes 100% renewable energy – a world first

This Island Is The First In The World To Be Powered Fully By Wind And Water BY ARI PHILLIPS MAY 1, 2014 THE SMALLEST AND SOUTHERNMOST OF SPAIN’S CANARY ISLANDS IS ABOUT TO MAKE AN OUTSIZED MARK ON THE PATH TOWARD A MORE RENEWABLE ENERGY-POWERED FUTURE. HTTP://THINKPROGRESS.ORG/CLIMATE/2014/05/01/3433002/SPANISH-ISLAND-RENEWABLE-ENERGY/

With the opening of a new wind farm next month, El Hierro, population just over 10,000, will become the first island in the world to be fully energy self-sufficient through combined wind and water power. The five wind turbines will provide 11.5 megawatts of power, enough to meet the demand of the population and the desalination plants on this small crop of land off the coast of Africa in the Atlantic Ocean.

When the wind isn’t blowing, hydropower will fill the void. When the wind is blowing, power will be used to pump water into a reservoir in a volcanic crater about 2,300 feet above sea level. Then when power is needed, that water will be released down to a lower reservoir and used to generate electricity on the way. This process is known as pump-storage hydroelectricity, and is used in many other countries across the globe — including the world’s largest outside of Washington, D.C.

“This system guarantees us a supply of electricity,” said the director of the Gorona del Viento wind power plant, Juan Manuel Quintero.

With the $75 million project set to come online, El Hierro will no longer have to rely on costly and dirty diesel generators for electricity — although it will maintain an oil power station just in case. According to Phys.org, the island’s transition to renewable energy will cut carbon dioxide emissions by 20,600 tons per year and save the island from using 40,000 barrels of oil a year.

Other islands are taking advantage of renewable resources to become wind- and solar-powered, but El Hierro is believed to be the first to do so exclusively with wind and hydro power and without having any connection to an outside electricity grid.

100,000 renewable energy jobs now in Britain

Renewable energy sector now supports over 100,000 UK jobs by ClickGreen staff. Published Wed 30 Apr 2014 The renewable energy industry has attracted nearly £30 billion of private sector investment since 2010, according to a new joint report published by the REA, Innovas and PwC.

The huge investment has enabled the industry to sustain over 100,000 jobs in 2013, generate turnover last year of £14 billion and deliver 4.2% of UK energy. 

The report, REview – Renewable Energy View: 2014, builds on the REA’s 2012 report Renewable Energy: Made in Britain, the first industry-wide analysis of employment in the UK renewable energy industry. 

green-jobs

The 116-page paper is the most complete assessment to date of the UK renewable energy market and will be formally launched this evening by Energy Minister Greg Barker in the House of Commons.

REA Chief Executive Dr Nina Skorupska said the report should provide the Government with a reminder of learning from past mistakes and provide market stability.

She added: “This report highlights the close relationship between clear, stable policies and sustained growth and jobs in the renewable energy industry. The Government’s renewable electricity policies have incentivised nearly £28 billion of private investment since 2010, achieving annual growth rates of over 20%. The world’s first Renewable Heat Incentive is also beginning to spur positive growth in green heating. This is a tremendous success story.

“This positive message also comes with a warning. Drastic Feed-in Tariff cuts in 2011/12 led to widespread job losses in the solar industry, and the continued policy uncertainty for renewable transport has seen employment and investment opportunities in UK refineries go begging.

“Clear, stable policies create the investment, jobs and growth in renewables that the UK needs. We urge the Government to learn the lessons from past experiences, such as solar FITs and biofuels uncertainty, and engage closely with industry to resolve outstanding uncertainties, such as State Aid rules and the details of CfDs.”

Analysis by the REA reveals that:

* Renewable electricity generation has grown steadily, increasing on average by 20.3% year-on-year between 2009 and 2013………

SunEdison going ahead with large solar energy plants

Flag-USASunEdison Lighting Up California (And Elsewhere) http://www.energymatters.com.au/index.php?main_page=news_article&article_id=4287 SunEdison has announced it has secured construction financing for the 60 MW Regulus solar power plant located in Kern County, California.

  Regulus will consist of around 250,000 solar panels and once operational; SunEdison will provide management and monitoring, field dispatch and reporting services via its Renewable Operation Center (ROC).
   
“Regulus is our largest North America project to date and is evidence of the momentum we are building in the California utility scale solar market,” said Bob Powell, SunEdison president of North America.
   
Announcements concerning SunEdison’s involvement in big ticket solar plants in California have become rather commonplace these days – just in the last couple of 6 weeks; the 24 MW Cascade solar farm and the 20MW Adobe Solar Facilityhave been brought online. 
  
Last Thursday, the company also announced it had secured financing from Deutsche Bank Securities Inc. for two solar power plants to be built in Ontario, Canada. Combined, the solar farms will supply enough clean energy to power 1,300 average households.
   
As well as large-scale flashy solar farms, SunEdison also has interests in helping out those less fortunate with clean energy too. 
 
Last Friday, the company dedicated a solar power system to the Mariposa Center for Girls in the Dominican Republic. The facility assists at-risk schoolgirls in support of the UN’s goals to increase energy access for all. SunEdison donated $10,000 in cash plus an in-kind donation of equipment  – a 9.9 kW solar panel system. 
   
“Electricity facilitates education, the delivery of healthcare services, and economic growth,” said Steve O’Rourke, senior vice president and chief strategy officer for SunEdison. 
   
“We are proud to support the UN’s Sustainable Energy for All initiative in this and future endeavors to ensure all people have access to clean, affordable energy.”

Investment analysts point to the opportunities in solar power

solar-panels-and-moneySolar Power on the Rise The Motley Fool, By Stephen O’Brien April 28, 2014 “…..The obvious solution is to substitute these fossil fuels with solar power. While the technology to harness the sun’s energy is perpetually being upgraded and refined, solar power is gradually becoming the most attractive choice for many consumers to power their homes, and not only for environmental reasons, but often for the lower costs solar energy is affording.

Flag-USAThe corporate sector has also begun to see solar’s advantages. IKEA has committed to becoming a zero-energy company 2020, and has allotted $2 billion for a number of renewable energy endeavors. It has already installed more than 550,000 solar panels. The company is additionally involved in wind energy, and has established a wind farm about a hundred miles south of Chicago and other wind projects in eight countries. In 2013, renewable energy sources accounted for close to 40% of IKEA’s energy usage.

Aside from such moves by a few of the larger corporations, demand for solar power has been increasing significantly in the U.S. residential market. SunPower (NASDAQ: SPWR  ) , a U.S. firm headquartered in San Jose, California, has been leasing its solar-panel systems to over 20,000 U.S. customers.

Demand for solar power around the world is also increasing rapidly. SunPower has offices in Europe, Australia, Africa and Asia to meet the growing cries for sun-generated energy. SunPower recently announced that it has begun selling megawatts of cell packages in inner Mongolia, and plans further moves to serve companies and consumers in China.It will have to contend, however, with the Chinese companies that currently serve the Chinese market, the leaders being Trina Solar (NYSE: TSL  ) and JinkoSolar (NYSE: JKS  ) .

Solar companies are in their early stages of development, and it is unclear who will become the dominant player a few years from now. Currently, there seems to be plenty of growth ahead for a number of solar companies. SunPower is said to have an advantage in that its solar panels are smaller in size and convert energy efficiently, making them well suited for rooftop installations.

Brean Capital recently initiated coverage on the company’s shares and rated them as a buy. SunPower’s stock currently has a forward price to earnings ratio of under 20, and its five-year growth rate in earnings per share looks to be over 30%, making the stock highly attractive to a longer-term investor who don’t mind price volatility. This company is clearly worth considering when investing in the solar sector, and in clean energy generally.

As the world shifts to solar power due to its increasingly cheaper cost or to ward off environmental catastrophe in the years ahead, a great investment opportunity has presented itself. While there certainly are strong competitors to SunPower, there is also a vast market for solar energy, and SunPower is poised to flourish……http://www.fool.com/investing/general/2014/04/28/solar-power-on-the-rise.aspx

‘photoswitches,’ – a coming breakthrough in solar energy?

Scientists Discover How to Generate Solar Power in the Dark Meet ‘photoswitches,’ a breakthrough set of materials that act as their own batteries, absorbing energy and releasing it on demand. THE ATLANTIC, APR 15 2014, The next big thing in solar energy could be microscopic.

Scientists at MIT and Harvard University have devised a way to store solar energy in molecules that can then be tapped to heat homes, water or used for cooking.

The best part: The molecules can store the heat forever and be endlessly re-used while emitting absolutely no greenhouse gases.  Scientists remain a way’s off in building this perpetual heat machine but they have succeeded in the laboratory at demonstrating the viability of the phenomenon called photoswitching……….

“One design we have for such an application is purely gravity driven – the material flows from one tank to another. The flow rate is restricted so that it’s exposed to the sun long enough that it gets fully charged. Then, when it’s time to cook dinner, after the sun is down, the flow direction is reversed, again driven by gravity, and the opposite side of the setup is used as the cooking surface.”

“As the material flows back to the first tank, it passes by an immobilized catalyst which triggers the energy-releasing process, heating the cooking surface up,” he adds.

Other versions of such device could be used to heat buildings.

Kucharski said the MIT and Harvard team is now investigating other photoswitching molecules and substrates, “with the aim of designing a system that absorbs more of the sun’s energy and also can be more practically scaled up.” http://www.theatlantic.com/technology/archive/2014/04/scientists-discover-how-to-generate-solar-power-in-the-dark/360679/

Vast majority of French people prefer renewable energy, would not invest in nuclear power

flag-franceFrance moving away from Nuclear power http://www.enn.com/energy/article/47327 27 April 14 France may be the world’s most nuclear energy dependent country, but times are changing as the country looks to increase the amount of wind—sourced electricity in its power mix. 

When French President François Hollande took the reins of power in 2012 he pledged to reduce the country’s nuclear dependency from 75% to 50% by 2025. Today, France has a goal of reaching 19 GW of wind energy by 2020, up from its current level of 8.2 GW, according to the European Wind Energy Association’s (EWEA) latest statistics. This will significantly raise the percentage of wind powered electricity in the country from the 3% wind covers today. And, according to a very recent survey, the French people are firmly behind the transition.

Some 64% of French people see wind energy as a solution, among others, in the context of the energy transition, says a CSA survey published in March 2014. Moreover, 80% of the 1010 respondents consider it necessary to invest in wind without waiting for the traditional power plants to reach the end of their lifecycle.

65% of those surveyed said that they would invest in renewable energy (wind and solar/photovoltaic) today if they had to personally invest in one energy source, while 15% chose nuclear, 7% chose gas and 1% chose coal. Meanwhile, 69% of French people would choose wind energy if they had to choose one energy type to be constructed in their region. 75% chose solar, 21% chose nuclear, 16% chose gas and 4% chose gas.

The results show that the French are aware that an energy transition must take place, they are confident enough in renewables to invest if they could, and they know that the time to act is now.
