Google pumps $12M into African solar energy project

By Jolie O'Dell | VentureBeat.com, Published: May 31, 2013

In is bajillionth green energy investment, Google has targeted the Jasper Power Project, a South African solar plant.

The investment totals $12 million and marks the search company’s first investment in Africa. This sum is part of a larger $260 million round including investors such as SolarReserve, a U.S. solar power developer; Intikon Energy, a South African renewable energy developer; and the Kensani Group, a South African empowerment investment firm.

The Jasper Power Project will be an advanced photovoltaic plant capable of generating 96 MW of clean energy for residents of South Africa. The project is designed not only to meet the country’s renewable energy goals but also to create long-term jobs and economic opportunity.

“Back in 2008, South Africa experienced a severe energy shortage, which resulted in blackouts throughout the country and slowed down economic growth,” writes Google energy and sustainability director Rick Needham today on the company blog.

“Since then the South African government has been actively supporting the growth of new sources of electricity to power the nation. … Given South Africa’s position as an economic powerhouse in Africa, a greener grid in South Africa can set an example for the whole continent.”

Previously, Google has made big investments in solar projects around the world. There’s a $168 million investment in a Mojave Desert power tower, a $94 million investment in photovoltaic projects throughout California, a smaller $5 million round for a plant in Germany, and a $280 million deal for SolarCity, which went public the following year.

All that is augmented by other investments in green energy, particularly wind farms.

Apple is planning a solar panel farm for its data center in Reno

By Katie Fehrenbacher | GigaOM.com, Published: July 2

Apple, working with Nevada utility NV Energy, is planning to build another solar panel farm next to a data center, and this time it’s for its new data center in Reno, Nevada. Apple has already been building two solar panel farms next to its data center in North Carolina, and this latest solar farm in Reno, called the “Ft. Churchill Solar Array,” shows Apple’s growing commitment to clean power at its new facilities.

Apple’s solar farm in Reno will be able to provide between 18 to 20 MW worth of power, which is about the same size as its two solar plants in North Carolina, which are both 20 MW in size. For an independent company (not a utility) — particular an internet company — 18 to 20 MW is a very large solar system.

But for the Reno solar farm, Apple is actually planning to use a new type of technology for the solar system, which includes both solar panels and also mirrors that concentrate the sun’s rays up to seven times onto the panels. That process increases the amount of power generated.

Apple is working with solar company SunPower on the engineering and construction, as well as the tracker technology that will be used with the solar panels. Apple also worked with SunPower for its North Carolina solar farms.

Apple’s partnership with utility NV Energy also shows how Apple is looking to work closely with utilities in states to create clean power options for its data centers. Apple is one of the first companies to take advantage of a new green tariff approved by Nevada’s utility commission that will enable Apple to pay for the cost of building the solar panel farm.

Since Apple will assume the incremental building costs throughout the project, the rates of NV Energy’s other customers doesn’t have to go up. Duke Energy and Google are working on a similar (though slightly different) proposal in North Carolina.

In the Nevada green tariff proposal, NV Energy can also pay Apple to use or even eventually buy the solar farm and include it in its energy generating assets. The Nevada state utility commission approved the green tariff on June 12. Apple has an option to expand the solar farm as well.

Because building the solar farm might take awhile, Apple plans to also use local geothermal power (the Galena 3 geothermal facility), which is widely available in the Reno area. Part of the reason that Apple chose to build its next data center in Reno, Nevada was because of the abundant clean power there.

The Apple Reno solar farm could create 100 jobs during the construction period.

Apple addressed the project in a statement:

All of Apple’s data centers use 100 percent renewable energy, and we are on track to meet that goal in our new Reno data center using the latest in high-efficiency concentrating solar panels. This project will not only supply renewable energy for our data center but also provide clean energy to the local power grid, through a first-of-its-kind partnership with NV Energy. When completed, the 137 acre solar array will generate approximately 43.5 million kilowatt hours of clean energy, equivalent to taking 6,400 passenger vehicles off the road per year.

NV Energy CEO Michael Yackira said in a statement:

We’re excited to be in partnership with Apple on a new solar energy project, the first project under our new Green Energy Program. This program allows customers such as Apple to choose to have a greater proportion of their energy coming from renewables than the law requires, without having a cost impact on our other customers.

Apple is looking to eventually use 100 percent clean power for its data centers through a combination of direct clean power generation, buying renewable energy credits and buying clean power from providers.

Suvolta’s energy-saving tech cuts an ARM chip’s power consumption in half

Chip startup Suvolta has developed a process that when used in manufacturing chips helps them conserve power, and it has shown off the results in a test with ARM. In that test, anARM microcontroller core consumed 50 percent less power than it previously would have running at 350 MHz. While these microcontroller cores aren’t the chips inside phones or servers, the Cortex M cores are ARM’s bet for the internet of things.

And if you think reducing power consumption on mobile devices is important, imagine having to plug in 40 or 50 sensors in order for your smart home to function. Those connected door locks or thermostats need power too.

Yet, that’s not all that’s packed into the news about Suvolta’s ARM partnership. Jeff Lewis, SVP business development and marketing with Suvolta, notes that what happens with the Cortex M core could be duplicated in the higher-level A-15 and other ARM cores that are used in mobile phones. So while the Suvolta technology isn’t designed into those or used for manufacturing ARM’s cores today, an ARM licensee could easily bring the power-saving tech to the upper tiers of ARM cores if it chose.

The technology works best for systems on a chip — multiple cores combined together onto one chip. SoCs, as they are called, are becoming more important as companies integrate more functions on one chip.

Suvolta on Tuesday also announced apartnership with UMC, a semiconductor manufacturing plant, where UMC can make chips using the Suvolta Deeply Depleted Channel process at sizes down to 28 nanometers. The chip-making process aims to cram as many transistors on a chip as possible, and the lower that process number is, the more advanced (and energy efficient) the chip is. The ARM core tested was manufactured at 65 nanometers.

I’ve been amped up about Suvolta for a few years now, and am excited that its technology is gaining ground with big name companies such as ARM. We’re placing computing in more places, but without new breakthroughs in battery life, those computers will have to have wires or compromise compute for battery life. With Suvolta, they can double their run-time without time-consuming architecture changes or expensive manufacturing techniques.

Nelson Mandela dies; former president of South Africa was 95

View Photo Gallery — Nelson Mandela dies at age 95: In an extraordinary life that spanned the rural hills where he was groomed for tribal leadership, anti-apartheid activism, guerrilla warfare, 27 years of political imprisonment and, ultimately, the South African presidency, Nelson Mandela held a unique leadership cachet that engendered respect and awe in capitals around the globe.

Nelson Mandela, the former political prisoner who became the first president of a post-apartheid South Africa and whose heroic life and towering moral stature made him one of history’s most influential statesmen, died Thursday, the government announced. He was 95.

The death was announced in a televised address by South African President Jacob Zuma, who noted, “We’ve lost our greatest son.” No cause was provided.

Timeline

Nelson Mandela, also known as Madiba, led the struggle to replace South Africa's apartheid regime with a multi-racial democracy. See key moments in his life.

Listen to an excerpt of Mandela's famous speech.

To a country torn apart by racial divisions, Mr. Mandela became its most potent symbol of national unity, using the power of forgiveness and reconciliation to heal deep-rooted wounds and usher in an era of peace after decades of conflict between blacks and whites. To a continent rife with leaders who cling to power for life, Mr. Mandela became a role model for democracy, stepping down from the presidency after one term and holding out the promise of a new Africa.

And to a world roiled by war, poverty and oppression, Mr. Mandela became its conscience, fighting to overcome some of its most vexing problems. He was a Nobel Peace Prize laureate who spent 27 years in prison as part of his lifelong struggle against racial oppression.

Throughout this moral and political fight, Mr. Mandela evoked a steely resolve, discipline and quiet dignity, coupled with a trademark big, charismatic smile. He ultimately carried them into office as South Africa’s first black president.

His victory capped decades of epic struggle by the African National Congress and other liberation groups against South Africa’s brutal white rulers, first under British colonialism and then under a white-run system called “apartheid,” or racial separation.

On the day of his inauguration — May 10, 1994 — Mr. Mandela stood at the podium near South Africa’s last apartheid-era president, F.W. de Klerk. A year earlier, they had shared the Nobel Prize for what the Nobel committee called “their work for the peaceful termination of the apartheid regime, and for laying the foundations for a new, democratic South Africa.”

“We have, at last, achieved our political emancipation,” Mr. Mandela, then 75, declared. “Never, never and never again shall it be that this beautiful land will again experience the oppression of one by another . . . the sun shall never set on so glorious a human achievement.”

Only a few years before, the 20th century’s most celebrated political prisoner had been dubbed a terrorist by the conservative governments in the United States and Britain under Ronald Reagan and Margaret Thatcher, respectively.

In the decades after Mr. Mandela’s release from prison in 1990, many South Africans of all races referred to him reverentially as Madiba, his Xhosa clan name. Countless others called him Tata, which means father in the Xhosa language.

For all his achievements, Mr. Mandela will also be remembered as slow to react to the HIV/AIDS epidemic that began sweeping South Africa on his watch. It was not until 1998, four years into his presidency, that he directly addressed the South African public about the disease. Later, he would acknowledge that he had not initially recognized the severity of the epidemic.
