Solar power could be world's top electricity source by 2050

Solar energy could be the top source of electricity by 2050, aided by plummeting costs of the equipment to generate it, a report from the International Energy Agency (IEA), the West’s energy watchdog, said on Monday.

IEA Reports said solar photovoltaic (PV) systems could generate up to 16% of the world’s electricity by 2050, while solar thermal electricity (STE) - from “concentrating” solar power plants - could provide a further 11%.

“The rapid cost decrease of photovoltaic modules and systems in the last few years has opened new perspectives for using solar energy as a major source of electricity in the coming years and decades,” said IEA Executive Director Maria van der Hoeven.

Solar photovoltaic (PV) panels constitute the fastest-growing renewable energy technology in the world since 2000, although solar is still less than 1% of energy capacity worldwide.

The IEA said PV expansion would be led by China, followed by the United States, while STE could also grow in the United States along with Africa, India and the Middle East. More

Energy Efficiency Simply Makes Sense

What simple tool offers the entire world an extended energy supply, increased energy security, lower carbon emissions, cleaner air and extra time to mitigate climate change? Energy efficiency. What’s more, higher efficiency can avoid infrastructure investment, cut energy bills, improve health, increase competitiveness and enhance consumer welfare — all while more than paying for itself.

Maria van der Hoeven - IEA

The challenge is getting governments, industry and citizens to take the first steps towards making these savings in energy and money.

The International Energy Agency (IEA) has long spearheaded a global move toward improved energy efficiency policy and technology in buildings, appliances, transport and industry, as well as end-use applications such as lighting. That’s because the core of our mandate is energy security — the uninterrupted availability of energy at an affordable price. Greater efficiency is a principal way to strengthen that security: it reduces reliance on energy supply, especially imports, for economic growth; mitigates threats to energy security from climate change; and lessens the global economy’s exposure to disruptions in fossil fuel supply.

In short, energy efficiency makes sense.

In 2006, the IEA presented to the Group of Eight leading industrialized nations its 25 energy efficiency recommendations, which identify best practice and policy approaches to realize the full potential of energy efficiency for our member countries. Every two years, the Agency reports on the gains made by member countries, and today we are working with a growing number of international organizations, including the European Bank for Reconstruction and Development, the Asian Development Bank and the German sustainable development cooperation services provider GIZ.

The opportunities of this “invisible fuel” are many and rich. More than half of the potential savings in industry and a whopping 80 percent of opportunities in the buildings sector worldwide remain untouched. The 25 recommendations, if adopted fully by all 28 IEA members, would save $1 trillion in annual energy costs as well as deliver incalculable security benefits in terms of energy supply and environmental protection.

Achieving even a small fraction of those gains does not require new technological breakthroughs or ruinous capital outlays: the know-how exists, and the investments generate positive returns in fuel savings and increased economic growth. What is required is foresight, patience, changed habits and the removal of the barriers to implementation of measures that are economically viable. For instance, as the World Energy Outlook 2012 demonstrates, investing less than $12 trillion in more energy-efficient technologies would not only quickly pay for itself through reduced energy costs, it would also increase cumulative economic output to 2035 by $18 trillion worldwide.

While current efforts come nowhere close to realizing the full benefits that efficiency offers, some countries are taking big steps forward. Members of the European Union have pledged to cut energy demand by 20 percent by 2020, while Japan plans to trim its electricity consumption 10 percent by 2030. China is committed to reducing the amount of energy needed for each unit of gross domestic product by 16 percent in the next two years. The United States has leaped to the forefront in transportation efficiency standards with new fuel economy rules that could more than double vehicle fuel consumption.

Such transitions entail challenges for policy, and experience shows that government and the private sector must work together to achieve the sustainability goals that societies demand, learning what works and what does not, and following the right path to optimal deployment of technology. Looking forward, energy efficiency will play a vital role in the transition to the secure and sustainable energy future that we all seek. The most secure energy is the barrel or megawatt we never have to use.

Maria van der Hoeven is the Executive Director of the International Energy Agency, an autonomous organization which works to ensure reliable, affordable and clean energy for its 28 member countries and beyond. This commentary appeared first this month in IEA Energy, the Agency’s journal.

Inside the Huge Solar Farm That Powers Apple's iCloud

Inside the Huge Solar Farm That Powers Apple's iCloud

This story was originally published by the Guardian and is reproduced here as part of the Climate Desk collaboration. The article was reported by the Guardian's Suzanne Goldenberg, and the video was produced by Climate Desk's James West.

The skies are threatening to pour on the Apple solar farm but as the woman in charge of the company's environmental initiatives points out: The panels are still putting out some power. Apple is still greening its act.

The company, which once drew fire from campaigners for working conditions in China and heavy reliance on fossil fuels, is now leading other technology companies in controlling its own power supply and expanding its use of renewable energy.

After converting all of its data centers to clean energy, the Guardian understands Apple is poised to use solar power to manufacture sapphire screens for the iPhone 6, at a factory in Arizona.

And in a departure for its reputation for secretiveness, Apple is going out of its way to get credit for its green efforts.

"We know that our customers expect us to do the right thing about these issues," Lisa Jackson, the vice-president of environmental initiatives told the Guardian.

This week the company invited journalists on a rare tour of its data center in North Carolina to showcase its efforts.

Until a year ago, the telegenic Jackson was the front woman for Barack Obama's environmental ambitions as the administrator of the Environmental Protection Agency.

Now she is leading the effort to shrink Apple's carbon footprint—and make sure customers realize the company is doing its bit to decarbonize its products and the internet.

Data centers require huge loads of electricity to maintain climatic conditions and run the servers carrying out billions of electronic transactions every day.

With Apple's solar farm, customers could now be confident that downloading an app or video-chatting a friend would not increase carbon pollution, Jackson said.

"If you are using your iPhone, iPad, Siri or downloading a song, you don't have to worry if you are contributing to the climate change problem in the world because Apple has already thought about that for you. We've taken care of that. We're using clean energy," she said.

The company is also moving to install solar and geothermal power at a plant in Mesa, Arizona, that has been manufacturing sapphire glass. Apple would not directly comment on the Arizona factory but the state's governor, Jan Brewer, has publicly praised the company's decision to relocate there and to use solar and geothermal in manufacturing.

"We are aware that almost 70 percent of our carbon footprint is in our supply chain," Jackson said. "We are actively working on the facilities that we have here in the United States."

The initiatives mark a turnaround for Apple, which was criticized in the past for working conditions and the use of toxic chemicals at its factories in China and for its heavy reliance on carbon intensive sources such as coal to power the cloud.

Greenpeace now says the company is out ahead of competitors like Google and Facebook, which also operate data centers in North Carolina.

"They are the gold standard in the state right now," said David Pomerantz, a senior Greenpeace campaigner. "There are a lot of data centers in North Carolina and definitely none has moved as aggressively as Apple has to power with renewable energy," he said.

The 55,000 solar panels tracking the course of the sun from a 400,000 square meter field across the road from Apple's data center in Maiden were not in the picture seven years ago when Duke Energy and local government officials sought to entice Apple to open up a data center in North Carolina.

Duke Energy, which has a near monopoly over power supply in the Carolinas, set out to lure big companies like Apple, Facebook and Google to the state with offers of cheap and reliable power for the data centers that are the hub of internet.

Data centers, with their densely packed rows of servers and requirements for climatically controlled conditions, are notorious energy hogs. Some use as much power as a small city. In Apple's case, the North Carolina data center requires as much power as about 14,000 homes—about three times as much as the nearby town of Maiden.

Charging up a smart phone or tablet takes relatively little electricity, but watching an hour of streamed or internet video every week for a year uses up about as much power as running two refrigerators for a year because of the energy powering data centers elsewhere.

That made data centers a perfect fit for Duke, said Tom Williams, the company's director of external relations. With the decline in textile and furniture factories that had been a mainstay in the state, the company had a glut of electricity.

"What the data centers wanted from Duke was low cost and reliable power. Those two things—cost and reliability—are fundamental to their operations," he told the Guardian. "What we like about these data centers is that it's an additional load on our system."

In the early days, Apple bought renewable energy credits to cover the center's electricity use. In 2012, the company built its first solar farm across the road from the data center.

Apple built a second solar farm, and announced plans this month for a third, all roughly about the same size, to keep up with the growing use of data. It also operates fuel cells, running on biogas pumped in from a landfill. All of the power generated on-site is fed into the electricity grid.

"On any given day 100 percent of the data center's needs are being generated by the solar power and the fuel cells," Jackson said.

The company has been less successful in its efforts to get other companies to switch to solar power. Duke, in cooperation with Apple, launched an initiative last year to encourage other big electricity users to go solar but so far there have been no takers.

Renewable energy accounts for barely 2 percent of the power generated in North Carolina, and Duke does not see the share growing significantly by 2020. More

IEA says ‘peak oil demand’ could hit as early as 2020

Little more that a year after the International Energy Agency added its voice to the chorus chiming that peak oil was dead, a new report from the uconservative adviser to industrialised nations suggests it has changed its tune. Only this time it is not peak supply that is on its radar, but peak demand.

The IEA’s Medium-Term Oil Market Report 2014 has predicted that global growth in oil demand may start to slow down as soon as the end of this decade, due to environmental concerns and cheaper alternatives, and despite boosting its 2014 forecast of global demand by 960,000 barrels per day.

While supply is forecast to remain strong – thanks largely to the unconventional, or “tight” oil revolution currently underway in north America – the IEA says it expects the global market to hit an “inflexion point”, by the end of 2019, “after which demand growth may start to decelerate due to high oil prices, environmental concerns and cheaper fuel alternatives.”

These factors, says the report, will lead to fuel-switching away from oil, as well as overall fuel savings. In short, it says, “while ‘peak demand’ for oil – other than in mature economies – may still be years away, and while there are regional differences, peak oil demand growth for the market as a whole is already in sight.”

It’s worrying news for the over-invested and under-prepared; not least of all oil importing nations, to which, as Samuel Alexander noted in this article last September, the economic costs of peak oil are especially significant.

“When oil gets expensive, everything dependent on oil gets more expensive: transport, mechanised labour, industrial food production, plastics, etc,” he wrote. “This pricing dynamic sucks discretionary expenditure and investment away from the rest of the economy, causing debt defaults, economic stagnation, recessions, or even longer-term depressions. That seems to be what we are seeing around the world today, with the risk of worse things to come.”

This then adds to the peak oil cycle, increasing governments’ motivation to decarbonise their economies – better late than never – “not only because oil has become painfully expensive, but also because the oil we are burning is environmentally unaffordable.”

This view has been echoed in numerous recent reports. US investment banks Sanford Bernstein raised the prospect of “energy price deflation”, caused by the plunging cost of solar and the taking up of market share by that technology as it displaced diesel, gas and oil in various economies. It predicted that could trigger a massive shift in capital.

Analyst Mark Fulton last month also questioned the wisdom of the private-sector investing over $1 trillion to develop new sources of high-cost oil production. While Mark Lewis, of French broking firm, suggested that $US19 trillion in revenuescould be lost from the oil industry if the world takes action to address climate change, cleans up pollution and moves to decarbonise the global energy system.

The IEA report also includes an updated forecast of product supply, which draws out the consequences of the shifts in demand, feedstock supply and refining capacity.

“Given planned refinery construction and the growth in supply that bypasses the refining sector, such as NGLs and biofuels, the refining industry faces a new cycle of weak margins and a glut of light distillates like gasoline and naphtha as a by-product of needed diesel and jet fuel,” it says.

It also predicts that “the unconventional supply revolution that has redrawn the global oil map” will expand beyond North America before the end of the decade, just as OPEC supplies face headwinds, and regional imbalances in gasoline and diesel markets broaden.

The report projects that by 2019, tight oil supply outside the United States could reach 650 000 barrels per day (650 kb/d), including 390 kb/d from Canada, 100 kb/d from Russia and 90 kb/d from Argentina. US LTO output is forecast to roughly double from 2013 levels to 5.0 million barrels per day (mb/d) by 2019.

“We are continuing to see unprecedented production growth from North America, and the United States in particular. By the end of the decade, North America will have the capacity to become a net exporter of oil liquids,” IEA Executive Director Maria van der Hoeven said as she launched the report in Paris. “At the same time, while OPEC remains a vital supplier to the market, it faces significant headwinds in expanding capacity.”

Beyond ageing fields, the major hurdle facing OPEC producers is the escalation in “above-ground woes,” as security concerns become a growing issue in producers like Iraq, and investment risks deter investment and exploration.

The report notes that as much as three-fifths of OPEC’s expected growth in capacity by 2019 is set to come from Iraq. The projected addition of 1.28 mb/d to Iraqi production by 2019, a conservative forecast made before the launch last week of a military campaign by insurgents that subsequently claimed several key cities in northern and central Iraq, faces considerable downside risk.

Pakistan’s First Solar Project Is One Of The World’s Largest

Last week Pakistan’s Prime Minister Nawaz Sharif inaugurated Pakistan’s first solar power park, which will start generating 100 megawatts of energy by the end of the year and a total of 1,000 megawatts by 2016.

Solar Farm in Bahawalpur, Pakistan

The Quaid-e-Azam Solar Park project has 400,000 solar panels, with a total cost of around $131 million. When complete the plant will produce about 2.5 times the power coming from the 392 megawatt Ivanpah solar thermal plant in California’s Mojave Desert, making it one of the largest solar parks in the world.

“If you come here after one and a half years, you will see a river of solar panels, residential buildings and offices — it will be a new world,” said site engineer Muhammad Sajid, pointing towards the surrounding desert.

This is big news for a country suffering from chronic energy shortages that leave people without power for large chunks of the day on a regular basis. And then there’s the nearly half of the households that aren’t even connected to the grid,according to a World Bank study. When temperatures soar in the summer, electricity demand can fall short by around 4,000 megawatts.

At the inauguration, the prime minister said “the dearth of electricity has pushed the country backwards and its entire industry and agriculture sector have suffered immensely.”

Pakistan is one of the most vulnerable countries in the world to the impacts of climate change due to its location, population, and environmental degradation. A recent study in the journal Nature Climate Change found that people are already migrating out of the Pakistan for climate-related reasons such as flooding and heat stress, which have negative effects on agriculture and can prove very costly.

“We need energy badly and we need clean energy, this is a sustainable solution for years to come,” Imran Sikandar Baluch, head of the Bahawalpur district administration in Punjab where the plant is located, told the AFP. “Pakistan is a place where you have a lot of solar potential. In Bahawalpur, with very little rain and a lot of sunshine, it makes the project feasible and more economical.”

At a meeting shortly after the inauguration, Sharif approved expanding the project from from 10,000 acres to 15,000 acres and increasing the capacity from 1,000 megawatts to 1,500 megawatts. More
