Abu Dhabi, United Arab Emirates - On the edge of the Arabian Peninsula's desolate Empty Quarter, hundreds of thousands of curved mirrors lined up in neat rows are quietly making electricity.

Sunlight bounces off the mirrors, which concentrate the rays to heat up a specially made liquid to almost 400 degrees Celsius. The scalding oil is then used to generate steam, which turns turbines that create electricity for about 20,000 homes in the United Arab Emirates (UAE).

This is Shams 1, the biggest single-unit concentrated solar power plant in the world when it opened last year. The idea behind concentrated solar isn't new: During the siege of Syracuse in 3rd century BC, the Greek inventor Archimedes was said to have used mirrors to focus the sun's rays on the invading Roman fleet, setting the ships on fire. (Perhaps as revenge for the stunt, Archimedes was killed by Roman soldiers after they won the siege.)

What is new is that oil-rich Middle Eastern countries - especially those in the Gulf region - have become increasingly bullish on solar power, in a bid to diversify their energy supply and perhaps turn a profit in the process.

For the Gulf's solar industry, 2013 was a year of firsts: In addition to the opening of Abu Dhabi's Shams 1 plant, Dubai's first solar power plant became operational, and Kuwait and Oman decided to build their first as well. In Saudi Arabia, one energy analyst found the cost of generating electricity from solar there had become as cheap as generating electricity from oil-fired power plants.

Saudi's solar goals appear to be the most gung-ho in the region: The kingdom has announced that it plans to throw down $109bn on solar energy and get one-third of its power from the sun by 2032. This target is "too ambitious", said Hussam Khonkar of Saudi Arabia's King Abdulaziz City for Science and Technology, but added the technology to do so is available.

Plummeting prices

So why now? "Before 2008, the cost of renewable generation was too high," said Yousif al-Ali, the general manager of Shams Power, which runs the Shams 1 plant. But in recent years, despite the global recession, Chinese companies manufactured huge amounts of photovoltaic solar panels. Now, said Ali, the cost of generating electricity from photovoltaic solar plants is in many cases as cheap as electricity generated by diesel.

You're seeing countries like UAE make substantial investments in renewables because they realise that clean energy is going to be one of the largest growth industries of the 21st century.


Just in the past five years, the price of photovoltaic panels has fallen by about 75 percent, according to Amit Ronen, the director of the George Washington University Solar Institute. This will make solar power more appealing in places where it wasn't previously thought affordable. "In 2014 and beyond, you're going to see a lot of new countries responding to these new economics around solar photovoltaic plants," said Matthew Campbell, senior director of SunPower, a US solar energy company.

Energy policymakers in the region realise the flush times won't last forever. At first glance, it's hard to take too seriously the energy issues faced by the Gulf countries, which have long stood among the world's biggest exporters of oil and natural gas. But the future doesn't look as sunny to those who worry their countries are at risk of squandering their geological inheritance.

'Systemic waste'

A 2013 report by London-based think-tank Chatham House detailed what it described as "systemic waste of natural resources" in the Gulf countries. If current trends continue, Saudi Arabia could be using all its oil production domestically in 15 years, said Khonkar.

Because petrol in the Gulf countries is subsidised at bargain-basement prices, a significant portion of the oil produced ends up in the fuel tanks of big SUVs at home. Because desalinated water is also provided to residents at low cost, the countries are among the most prodigious users of water in the world - which also takes a toll on fuel supplies. Because more workers are brought into the region each year to build infrastructure and staff the service industry, the demand for energy has continued to ratchet up.

Yet luckily for them, the Gulf's oil-rich countries are even more sun-rich. The Arabian Peninsula is among the sunniest places in the world, ranking alongside other solar hotspots such as Arizona and parts of South America's Andes Mountains. A single square kilometre of land in Qatar receives as much solar energy in one year as is contained in 1.5 million barrels of oil, according to one study.

Exporting clean energy

The UAE has been the most proactive in the region in promoting alternative energy. Its government said it plans on spending $350m on renewable energy projects in developing countries, and its capital, Abu Dhabi, hosts the International Renewable Energy Agency.

In recent years, the Abu Dhabi Fund for Development and Masdar, a clean energy company owned by Abu Dhabi's government, have developed and funded a major solar plant in Mauritania, a wind farm in the Seychelles, and planto launch renewable energy projects in five Pacific island states as well.

Self-interest is one factor driving the country's policy. "You're seeing countries like UAE make substantial investments in renewables because they realise that clean energy is going to be one of the largest growth industries of the 21st century," said Ronen. "And they want to get in the game."

But is it 'green'?

Reports of solar energy's spread in the Gulf would seem to be heartening news to environmentalists. If even major oil exporters are planning large-scale alternative energy projects, surely there's hope that global climate change can be curbed before it's too late?

On the other hand, it may be facile to assume that a potential solar bonanza in the Gulf will necessarily be a green one. With crude oil selling for more than $100 a barrel in recent years, exporters may figure they can make more money if they use less of the stuff at home, and sell more abroad.

Developing more renewable energy capacity will allow the Gulf countries to "keep making money exporting their oil and natural gas and create more jobs at home", said Ronen. "It's not like the natural gas is staying in the ground because of the solar."

As economist Jeffrey Sachs noted this week at the International Renewable Energy Agency's annual assembly in Abu Dhabi, it's not enough merely to develop alternative sources of energy: In order to limit global warming, one also has to limit the use of fossil fuels.

In the post-Fukushima era, some environmentalists may also recoil at another strategy considered by some Gulf states to diversify their energy supply: nuclear power. Saudi Arabia is considering building several nuclear reactors that could cost up to $100bn, and the UAE plans on having four plants operational by 2020.

Sun Kings: Can Solar Power Solve Pakistan’s Energy Crisis?


Amid an ever-worsening energy shortage in Pakistan, the country’s parliament has chosen an alternative source of power: solar. A 1.8-megawatt (MW) solar power plant funded by the Chinese is being installed in Parliament House in Islamabad, which the Pakistan government hopes will save some $1 million in its annual energy utility bills and reduce greenhouse gas emissions. AlertNet, part of the Guardian newspaper’s Environment Network, reported that construction of the solar panels commenced in the first week of the New Year. The Chinese government is picking up the tab of the initial cost (of about $60 million) as a gesture of friendship between the two Asian giants.

This is the first project of its kind [in a public building] in Pakistan, and late, more public buildings will be converted to solar power to overcome the energy crisis,” said Munawar Abbas Shah, a special secretary at the National Assembly (the lower house of Pakistan’s Parliament). Both the National Assembly and the Senate (upper house of parliament) meet in the building. “The consumption of electricity in the parliament even jumps over 2 MW in summers when the house is in session,” Shah added. AlertNet noted that while Pakistan does not plan a comprehensive switch to solar power, it has enlisted Chinese help to build a 10,000-acre solar park in Punjab province, which could generate 1,000 MW.

Separately, in a country where millions of people are not even connected to the national electricity grid (and even millions more who are connected suffer periodic power outages that can last for hours), solar energy may offer a form of relief. According to the World Bank report, almost half (44 percent) of all households in Pakistan are not connected to the electricity grid. About four-fifths of these families are located in rural regions, leading many of them to use kerosene as a source of light. Iftikhar Ahmad Qaisrani, founder of the Renewable Energy Society for Education, Awareness Research and Community Help, an Islamabad-based renewable energy advocate, said that Pakistan needs investments from the government and private sectors to build a solar power infrastructure, noting that the county enjoys 320 days of sunshine annually and about eight hours of sun every day.

Qaisrani also noted that Pakistan is far behind India and Bangladesh on these fronts -- these nations have already significantly engaged the use of solar power in rural and farming areas (where people also lack links to the electricity grid). But Pakistan, he added, must make it economical and practical. “Installation of solar power is a one-time expenditure, and people should be encouraged to avail [themselves of] the opportunity,” he said. “This is the right time to encourage the public and private sector to focus on solar energy and provide off-grid solutions to people living in far-flung areas of the country.”


Qaisrani estimated that it would cost between $3,500 and $4,000 to convert an individual home to solar power -- a rather large expenditure for the average Pakistani household. But he pointed out that such a system could deliver continual energy for 25 years. “Pakistan can also save millions of dollars [in] foreign reserves per [year] just by switching to solar power,” Qaisrani further noted, citing that fossil fuels still account for almost two-thirds (65 percent) of annual power generation in the country. Since half of that fuel has to be imported, Pakistan’s power supply can be quite costly.

But solar energy is not cheap either -- at least in the short term, since parts necessary for solar panels and power systems must be manufactured overseas (principally from China, Japan and Germany) and imported. These costs are exacerbated by heavy import duties slapped on solar power units. Abdul Hanan Siddhu, a solar energy consultant, urges the Islamabad government to do away with such taxes. “The government should also encourage local manufacturers to start cell manufacturing to reduce the cost,” he said. ”On top of this, government subsidies could help boost the solar off-grid lighting sector.”

In an op-ed published in the Express Tribune newspaper, Ahsan Ashraf said Pakistan should pursue solar and wind power instead of nuclear energy. “We have ample supplies for wind and solar power, which we can use to tackle our energy crisis,” Ashraf wrote. “With Pakistan’s incredible potential of untapped renewable resources, why is Pakistan trying an untested nuclear technology when the rest of the world is moving towards greener energy solutions?”

Ashraf noted that advocates of nuclear power in Pakistan over-estimate the country’s ability to meet economic targets and overcome the failures of its incompetent and corrupt government. “In order for Pakistan to meet its own nuclear development estimates, it would have to emulate and surpass the efforts of countries like the United States and France. This idea seems highly unlikely and unrealistic to me,” he declared. “Development of nuclear power requires long-lasting coordination between private and government sectors and a strong government effectiveness and control of corruption, since nuclear projects require large capital expenditures. Compared to countries like the United States, France and South Korea, that have developed nuclear power at impressive rates in the past, Pakistan cannot compare in government effectiveness and control of corruption.”

Solar and wind, in contrast, can be developed much more easily and can eventually provide safe, cheap power to a country in need of such blessings. Ashraf cited the example of a Pakistani village called Narian Khorian (near Islamabad), which has installed 100 solar panels with help from a local company. “Today, all houses in the village have sufficient energy to run an electrical fan and two light bulbs,” he said. “An average solar panel lasts almost 25 years and has no maintenance costs associated with it. There is no downtime or risk of failures that may cause large-scale evacuations or other threats to life and/or property. This is the solution that Pakistan has been looking for: A change that is driven by the people on fundamental grassroots level.”

Meanwhile, Pakistan is likely to endure worsening power surges, especially in its sweltering summers when demand surges beyond the capacity of the existing electrical grid. Power outages lasting 18 to 20 hours a day are not unusual across Pakistan -- all of which hurts an already faltering economy. The extended absence of electrical power leads to wasted food in refrigerators and families unable to cook, clean or wash, and hospital patients in grave danger, not to mention the extreme discomfort of dealing with heat and humidity.

There are many reasons why Pakistan undergoes repeated power outages, but it basically all boils down to soaring demand mixed with mismanagement and corruption among virtually all levels of government. The public’s discontent has manifested itself in frequent street protests that frequently turn violent. “Pakistan’s dilemma on the electricity front does not have to do with the capacity already installed for generation purposes, noted Farhan Bokhari, writing in the Gulf News newspaper. Instead, the shortages are driven mainly by the inability of the government to pay for electricity produced by privately owned companies, as it tries to overcome a ballooning fiscal deficit -- thanks to the visible squandering of precious budgetary resources. “Tackling such a challenge in part must also be linked to inspiring the broad mainstream public across Pakistan, Bokhari added.

On a daily basis, Pakistan’s power demand averages 16,000 MW, but the nation can produce only about 12,000 MW. In the summer months, this gap can be as high as 7,000 MW, Reuters reported. Bilal Mustafa, who sells solar energy kits to households as the owner of Hussain Electronics in Rawalpindi, said demand has jumped in the past few years. “One of the reasons behind the soaring demand for solar energy systems is itself the sale of the systems. People watch others using solar power and they hanker to try it out, too,” he said.
