On Tuesday, May 24, Nigerian Central Bank Governor Godwin Emefiele announced that the country will adopt a more flexible foreign exchange rate system in the near future. This move signals a major policy shift by Emefiele and President Muhammadu Buhari, who had until this point opposed calls to let the naira weaken. Many international oil-related currencies have depreciated against the dollar as oil prices began their decline in 2014. Nigeria, however, has held the naira at a peg of 197-199 per U.S. dollar since March 2015, depleting foreign reserves and deterring investors, who remain concerned about the repercussions of a potential naira devaluation. Following the announcement, Nigerian stocks jumped to a five-month high and bond prices rose in anticipation that a new flexible exchange rate regime would increase the supply of dollars and help attract foreign investors.

For now it remains unclear exactly what a more flexible system will entail for Nigeria, however, some experts suggest that the Central Bank may introduce a dual-rate system, which allows select importers in strategic industries to access foreign currency at the current fixed rate, while more generally foreign currency will be available at a weaker, market-related level. This new regime raises a number of questions, including how it will be governed and who will have access to foreign currency (and at what rate). On Wednesday, Nigeria’s parliament requested a briefing soon from Emefiele and Finance Minister Kemi Adeosun to provide additional clarity on the new system, although the date for such a meeting has not yet been set.

Earlier this month, Kenya announced plans to close the Dadaab refugee camp, located in northeast Kenya, amid security concerns. The move to close the camp has been widely criticized by international actors. United States State Department Press Relations Director Elizabeth Trudeau urged Kenya to “uphold its international obligations and not forcibly repatriate refugees.” The United Nations High Commissioner for Refugees stated that the closure of the refugee camp would have “devastating consequences.” Despite these concerns, this week, at the World Humanitarian Summit, Kenya stated that it will not go back on its decision and confirmed the closure of the refugee camps within a six-month period.

The camp houses 330,000 refugees, a majority of whom fled from conflict in their home country of Somalia. Kenya insists that the camp poses a threat to its national security, as it believes the camp is used to host and train extremists from Somalia’s Islamist group al-Shabab. Kenya also argued that the developed world, notably the United Kingdom, should host its fair share of African refugees. This is not the first time Kenya has threatened to close the refugee camp. After the Garissa University attacks last April, Kenya voiced its decision to close the refugee camps, although it did not follow through with the plan.

From May 23-27, Lusaka, Zambia hosted 5,000 delegates and participants for the 2016 Annual Meetings of the African Development Bank (AfDB), with the theme, “Energy and Climate Change.” Held in the wake of December’s COP21 climate agreement and in line with Sustainable Development Goals 7 (ensure access to affordable, reliable, sustainable and modern energy for all) and 13 (take urgent action to combat climate change and its impacts), the theme was timely and, as many speakers emphasized, urgent. Around 645 million people in Africa have no access to electricity, and only 16 percent are connected to an energy source. To that end, AfDB President Akinwumi Adesina outlined the bank’s ambitious aim: “Our goal is clear: universal access to energy for Africa within 10 years; Expand grid power by 160 gigawatts; Connect 130 million persons to grid power; Connect 75 million persons to off grid systems; And provide access to 150 million households to clean cooking energy."

As part of a push to transform Africa’s energy needs and uses, Rwandan President Paul Kagame joined Kenyan President Uhuru Kenyatta on a panel to support the AfDB’s “New Deal on Energy” that aims to deliver electricity to all Africans by 2025. Kenyatta specifically touted the potential of geothermal energy sources. Now, 40 percent of Kenya's power needs come from geothermal energy sources, he said, but there is still room for improvement—private businesses, which make up 30 percent of Kenya’s on-grid energy needs, have not made the switch yet.

As part of the meetings, the AfDB, the Organization for Economic Cooperation and Development (OECD), and United Nations Development Program (UNDP) also launched their annual African Economic Outlook, with the theme “Sustainable Cities and Structural Transformation.” In general, the report’s authors predict that the continent will maintain an average growth of 3.7 percent in 2016 before increasing to 4.5 percent in 2017, assuming commodity prices recover and the global economy improves.  However, the focus was on this year’s theme: urbanization. The authors provide an overview of urbanization trends and highlight that successful urban planning can discourage pollution and waste, slow climate change, support better social safety nets, enhance service delivery, and attract investment, among other benefits.

This election cycle, what will separate Democrats from Republicans on energy policy and their approach to climate change? Republicans tend to be fairly strong supporters of the fossil fuel industry, and to various degrees deny that climate change is occurring. Democratic candidates emphasize the importance of further expanding the share of renewable energy at the expense of fossil fuels, and agree that climate change is a real problem—with some saying the challenge trumps most, if not all, other U.S. security concerns.

Now that there are presumptive nominees for both major political parties, it’s an important moment to outline, in broad strokes, the positions of Secretary Hillary Clinton and businessman Donald Trump. We realize that Democratic Presidential candidate Bernie Sanders has not dropped out of the race, but note that it is fairly unlikely at this point that he would clinch the nomination.

Clinton: Building on the Obama legacy 

Secretary Clinton has laid out the most comprehensive and detailed energy and climate policy proposals of the candidates to date. They are in essence a continuation, and in some cases a further expansion, of existing White House policies under President Obama. The Secretary has stated that she wants the United States to be the “clean energy superpower of the 21st century.”

This starts with the notion that climate change is an existential threat, which the global community has to address as soon as possible. In order to do that, in her view, the United States needs to continue to show leadership on the international stage, as the Obama administration sought to do surrounding the Paris agreement in December 2015. This will require substantial reforms to expand low-carbon options, including nuclear energy to some degree, while tightly regulating fossil fuels (and gradually phasing them out). 

[S]he wants the United States to be the “clean energy superpower of the 21st century.”

The first casualty of this transformation is the coal industry, which Clinton has explicitly acknowledged. She presented a $30 billion plan to revitalize communities where coal production is currently an important industry and job creator, for example, and has campaigned with this message in various state primaries. Implicitly, Secretary Clinton does not seem to believe in the economic viability of carbon capture and sequestration in the United States—this is despite the fact that most analyses, including those of the Intergovernmental Panel on Climate Change (IPCC), suggest that this technology could be a cost-efficient tool in a wider carbon emission mitigation portfolio. 

Clinton sees natural gas as a bridge fuel, though at this point it’s not clear how long that bridge is. Questions remain about the role that natural gas can play in scenarios of deep decarbonization in 2030 and beyond. At the moment, the gas industry is rather nervous of the Secretary’s statement that she’d increase regulations on, in particular, the fracking industry—if her conditions came to fruition, there would very few places where fracking would continue. 

Secretary Clinton believes that oil consumption has to be cut substantially in the coming years, and she has suggested that new drilling in places like the Arctic, off the Atlantic Coast, and on federal lands would be discouraged or banned. She has previously opposed crude oil exports, though we would not anticipate a roll-back of existing policies (in December 2015, the Obama administration lifted the decades-old ban). 

Clinton foresees a new energy economy built on rapidly increasing shares of renewable energy, which should comprise 25 percent of the U.S. fuel mix by 2025 according to her plan (solar energy would be a key focus, with half a billion panels to be installed by the end of her first term). To facilitate this transition, she presented an elaborate energy infrastructure plan to modernize the U.S. grid and improve efficiency in reviewing and approving projects. 

Tax credits to support renewables would be continued under a Clinton White House, whereas fossil fuel subsidies would be phased out. Increased energy efficiency, including harmonization of vehicle efficiency and fuel standards, are high on her agenda as well. The Secretary also supports the Clean Power Plan that the Environmental Protection Agency under the Obama administration has launched, and which is currently on hold in the Supreme Court. 

On the international stage, Clinton supports the Paris agreement on climate change. Should she win the presidency in November, she would make an effort to take this Treaty to the next step, thus continuing U.S. leadership. That would mean reinforcing U.S. leadership along the lines described above, while helping address current uncertainties about finance, transparency, and accountability, to name only a few challenges that remain.

Trump: Drill, baby, drill

Although Donald Trump’s candidacy remains highly controversial, he is now the presumptive Republican nominee for president. To the extent that we know any detailed plans, quod non, it is safe to say that his views on energy and climate change are diametrically opposed to most of Clinton’s. Broadly speaking, Mr. Trump has come out as a fervent supporter of the fossil fuel industry, and has expressed skepticism about the economic viability of renewable energy.

Mr. Trump’s views start with the belief that climate change is not man-made. In the past, the controversial businessman has suggested that climate change might be a hoax invention from China, in order to undermine U.S. industrial interests and job creation. This starting point allows Mr. Trump to be extremely supportive of existing industrial interests (if carbon and other greenhouse gas emissions are not a problem, the thinking goes, then business as usual is the way to go). 

In a speech in North Dakota in late May, Mr. Trump laid out some broad initial ideas for his energy policy. He declared that under his presidency the United States would “accomplish complete American energy independence,” leaving unaddressed arguments about what that would mean for existing international energy trade. 

It is probably safe to say that Mr. Trump would like to further expand oil, gas, and coal production in the country. The latter, in particular, is remarkable: even coal executives have declared that market forces (particularly very competitive natural gas) have been the primary threat to the coal industry. Since Mr. Trump is also a strong supporter of the natural gas industry—and considering the challenges of building new bulk terminals for exports—it is unclear how a revitalization of the coal industry would occur. 

If climate change is a hoax, it will come as no surprise that Mr. Trump will not support efforts to mitigate carbon and other greenhouse gas emissions.

Contrary to his opponent, Mr. Trump would also like to revoke restrictions on drilling for oil and gas, and would permit production on federal lands. He also supports further expansion of energy infrastructure, and would, if elected, ask Trans Canada to resubmit a permit application for the Keystone pipeline, which he’d approve. He has caveated his support for projects like these by demanding that a portion of the revenues from oil and gas flows be redistributed to local communities, to compensate them for intrusion on their private property. Mr. Trump has also indicated that he wants to use revenues from oil and gas production to rebuild U.S. infrastructure more broadly.

If climate change is a hoax, it will come as no surprise that Mr. Trump will not support efforts to mitigate carbon and other greenhouse gas emissions. The candidate has called the Obama administration’s Clean Power Plan “stupid,” and when asked what he would do about the Paris agreement on climate change, he said he’d cancel it. 

Though Trump says the United States must pursue all forms of energy—including renewables—he has expressed skepticism about their economic viability, calling solar energy “very expensive.” Wind energy received similar pejorative feedback, since Trump says it kills eagles and is noisy. During one of the few debates about renewable energy during the Iowa primary, he voiced his support for blending biofuels in vehicles. 

To the polls

The 2016 U.S. presidential election will have a profound impact on global affairs. Not only will it affect a range of security and economic issues in important ways, it also means a lot for global energy and climate policy. Will the United States continue on the trajectory that President Obama has started and continue a major energy transition strategy? Or will it shift course, potentially undermining existing domestic policies and investments, as well as international obligations? In November 2016, the American people will decide.

Saudi deputy crown prince and defense minister Mohammad bin Salman is just wrapping up a heavily hyped visit to Washington, aimed at reinforcing the kingdom’s partnership with the United States. Recent years have frayed what is traditionally the central strategic relationship for Riyadh, principally over the Obama administration’s nuclear diplomacy with Iran.

Since the conclusion of the Iranian nuclear deal last July, the perennial antagonism between Riyadh and Tehran has reached a dangerous pitch, fueling the violence that rages in Syria, Iraq, and Yemen and the undercurrent of instability that saturates the region. And the fallout of their rivalry has left its mark well beyond the boundaries of the Gulf, exacerbating volatile energy markets and, by extension, the global economy. 

Within OPEC, Riyadh and Tehran are eyeing each other warily, and their continuing differences torpedoed a proposed ceiling on oil production at OPEC’s latest meeting. The outcome was not surprising; a similar effort to agree on a production freeze between the group and a handful of non-OPEC producers fizzled in April. In the meantime, any incentives for drastic measures to address soft oil prices have abated as oil prices creep back up to approximately $50 a barrel. 

Iran and Saudi Arabia have plenty of reasons to continue pumping for the foreseeable future. Since the lifting of nuclear-related sanctions in January, Iranian leaders have been determined to make up for lost time and lost revenues, already defying expectations by quickly raising production to levels that hadn’t been reached since November 2011 and aggressively cutting prices in hopes of winning back its pre-sanctions export market. 

The centrality of oil to the legitimacy and autonomy of both regimes means that these plans are little more than publicity stunts.

Meanwhile, Saudi Arabia appears prepared to continue pumping at record-high levels, part of a larger strategy aimed at maintaining market share and driving down non-OPEC production. The two states’ economic incentives are compounded by their fierce geostrategic and sectarian rivalry, which has intensified, as evidenced by the standoff over Iranian participation in the annual pilgrimage to Mecca.

But even as the two states duel over oil production and prices, both Saudi Arabia and Iran are conspicuously planning for a post-oil future. Leaders in both countries have decreed an end to the era of oil dependency, endorsing ambitious blueprints for restructuring their economies that—if implemented—would ultimately transform state, society, and the wider region. The centrality of oil to the legitimacy and autonomy of both regimes means that these plans are little more than publicity stunts. Still, just imagine for a moment what it would mean for Iran, Saudi Arabia, and the Middle East if these grandiose agendas were adopted.

Competing and complementary visions

Tehran’s plan actually dates back more than a decade, with the 2005 release of its “20 Year Perspective” (sometimes called “Vision 2025”). The plan laid out extravagant expectations: rapid growth and job creation, diversification away from oil, a knowledge-based economy. Intervening developments—sanctions that targeted Iran’s oil exports and helped expand non-oil trade—have only bolstered the rhetorical commitment of Iran’s supreme leader, Ayatollah Ali Khamenei, to a “resistance economy” in which oil exports constitute a minor part.

“One of our most serious losses is dependence on oil,” Khamenei bemoaned in a 2014 speech. “I am not saying that oil should not be used. Rather, I am saying that we should reduce our dependence on selling crude oil as much as we can.” 

Not to be outdone, Saudi Deputy Crown Prince Salman announced Saudi “Vision 2030,” to address what he described as “an addiction to oil.” The plan, which has met with equal doses of fanfare and skepticism since its announcement last month, aims to create a “thriving economy” and end Saudi dependence on oil revenues by 2020. Vision 2030 includes provisions to sell off a small stake in the kingdom’s state oil company, Saudi Aramco, and create the world’s largest sovereign wealth fund to manage the country’s income, as well as goals of creating 450,000 new private sector jobs, cutting public sector wages, and tripling the country’s non-oil exports all within the same abbreviated time frame.

Jeopardizing domestic stability

There is one hitch, however: these aspirations, though laudable, are preposterously unmoored from current political and economic exigencies. The institutions of governance and the structure of power in resource-rich states such as Saudi Arabia and Iran are organized around the state’s role as purveyors of vital social and economic goods. Riyadh and Tehran distribute cash handouts, provide jobs in already-bloated state bureaucracies, and levy few taxes. Diversifying away from reliance on oil would essentially require Riyadh and Tehran to radically curtail this distributive role, inviting historic social and political changes that could ultimately compromise regime ideology and weaken state legitimacy. 

[T]hese aspirations, though laudable, are preposterously unmoored from current political and economic exigencies.

In Saudi Arabia, the supply of these benefits is central to the monarchy’s legitimacy. To diversify away from oil, which currently accounts for over 70 percent of government revenues, Riyadh would have to drastically cut spending, far more than it already has. Not only would this further slash subsidies and hike fees, it would also effectively force Saudi workers—two-thirds of whom are employed by the state—to take up private sector jobs, 80 percent of which are currently staffed by expatriates. To accomplish this transition would require fundamental changes to the incentive structure for the Saudi labor force: a much broader willingness to accept low-skill, low-wage jobs, as well as the requisite improvements in education and productivity to support larger numbers of Saudi nationals moving into private sector positions.

For the Saudi economy to be truly competitive, Riyadh would have to initiate dramatic changes to a central component of the Saudi social compact—women’s rights and freedoms. The Vision 2030 document boasts that over 50 percent of Saudi university graduates are women and pledges to “continue to develop their talents, invest in their productive capabilities and enable them to strengthen their future and contribute to the development of our society and economy.” 

But the domestic Saudi labor force is overwhelmingly male, and even the plan’s modest aspirations to raise female participation in the workforce from 22 to 30 percent are likely to run into logistical and social obstacles. Shortly after announcing Vision 2030, Deputy Crown Prince Salman said Saudi Arabia is not yet ready to let women drive. A diversified economy will not emerge in the kind of constricted social environment mandated by the Saudi interpretation of sharia (Islamic law). 

Iran’s Islamic Republic doesn’t have the same degree of gender segregation, but Iran’s official interpretation of Islam has still constrained female participation in the workforce. Iran employs an equally low percentage of women—according to a 2014 U.N. report around 16 percent—and women’s unemployment is more than double that of men (nearly 20 percent).

The bigger challenge for Iran will be truly opening up its economy to foreign direct investment. This remains hotly contested among the leadership, even in the aftermath of the nuclear agreement and the lifting of related sanctions. While there is some consensus around the need for foreign capital and technology, hardliners including Khamenei are determined to insulate Iran from any accompanying cultural influence and dependency. As the supreme leader recently inveighed, the global economy is “a plan and system that has been devised mainly by Zionist capitalists and some non-Zionists with the purpose of usurping the economic resources of the whole world...If a country merges its economy with the global economy, this is not a source of pride, rather it is a loss and a defeat!”

This deeply-rooted paranoia has provided a convenient platform for the Islamic Republic to galvanize citizens’ loyalty to the state and hostility to outside interference. And it also inhibits the liberalization that makes foreign investment possible: measures to enhance transparency and security, develop more attractive legal and fiscal frameworks, shrink the role of the state, and undertake an array of other structural reforms. Without these measures, Tehran will struggle to capitalize on its extraordinary reengagement with the world. 

While Saudi Arabia has maintained a more consistent and mutually beneficial pattern of foreign investment, its leadership too will have to revamp its approach if it is to broaden its economic base. For Riyadh, the challenge is less one of attracting foreign capital than of developing a sustainable influx of technology and expertise to develop sectors other than energy. The kingdom will also have to overcome serious regulatory hurdles and a proclivity for mammoth (and often white elephant) projects.

Compromising regional clout

Riyadh and Tehran will need to balance their economic aspirations and their approach to the region, too. Historically, their role in global energy markets has largely shielded both states from the fallout of regional instability. The world’s need for reliable oil at reasonable prices has inculcated the commitment of outside powers to secure transportation of resources and considerable autonomy for Riyadh and Tehran from the implications of their own policies. 

As a result, Saudi Arabia and Iran can fund nefarious activity across the region, violate the civil and human rights of their citizens and other residents, and carry out belligerent foreign policies without severe repercussions for their oil revenues. Only in the past five years has Tehran seen the limits of the world’s reluctance to jeopardize its investment with a major oil exporter; and the recent reversal of the U.N. condemnation regarding the Saudi-led coalition in Yemen demonstrates that Riyadh remains insulated.

Saudi Arabia and Iran can fund nefarious activity across the region, violate the civil and human rights of their citizens and other residents, and carry out belligerent foreign policies without severe repercussions for their oil revenues.

Regional developments make the prospect of economic diversification even less likely, as sensitivity to such developments will only increase if either country successfully develops its non-oil sectors. At the same time, regional stability is a basic prerequisite for economic diversification. Robust growth and good governance throughout the Middle East would provide the optimal context for the economic transformation of Iran and Saudi Arabia, since the marketplace for their non-oil exports is concentrated in the immediate neighborhood. But such transformation would require both countries to put economic priorities that serve their general populations above the ideological and religious agendas—supported by oil rents—that propel their regional and international influence and that provide a large portion of their autonomy in foreign policymaking. 

Technocrats in both countries understand this intuitively. At a 2015 conference on Iran’s economy, President Hassan Rouhani wondered “How long can the economy pay subsidies to politics?” He added that the country’s economy “pays subsidies both to foreign policy and domestic policy. Let us try the other way round for a decade and pay subsidies from the domestic and foreign policy to the economy to see [what] the lives and incomes of people and the employment of the youth will be like.” The problem, of course, is political will: neither country is prepared to elevate the interests of its people over the demands of ideology.

Imagining an unlikely future

Can either Iran or Saudi Arabia really kick the oil habit? It seems exceptionally unlikely. Even as Khamenei extols the need for inward-focused development, Tehran is racing to expand crude output level to four million barrels per day by March 2017. 

Oil enabled the creation of the modern Middle Eastern state and fueled the rise of both countries to regional predominance. Oil is a vector for their regional rivalry, and it provides prestige and funds to be used in other arenas of competition. A genuine diversification of the two largest economies in the Middle East and North Africa would jeopardize their revenue streams and domestic legitimacy, as well as their efforts to assert their primacy across the Islamic world.

[N]either country is prepared to elevate the interests of its people over the demands of ideology.

“All success stories start with a vision,” Deputy Crown Prince Salman is quoted as saying on the Vision 2030 website. But vision is insufficient to bridge the gap between aspiration and reality; a serious agenda to implement either the Saudi or the Iranian vision would require painful compromises to regime ideology and a fundamental overhaul of the institutions and the structure of power in both countries. 

Imagine, though, for a moment, that these far-fetched ambitions were quite serious, and that both the Saudi and Iranian leadership were determined to do what was necessary to truly wean their economies off oil dependence. Consider what it might mean for the region if these grandiose ambitions were not simply the illusions of overpriced consultants and embattled technocrats—if a leadership emerged in one or both of the Middle East’s most powerful actors prepared to invest political capital in a genuine transformation of priorities and policies. What might be possible if Tehran and Riyadh sought to compete for economic opportunities instead of fueling violence and sectarianism around the region? If instead of a vicious sectarian and geopolitical rivalry, these two old adversaries engaged in a race to the top?

What will it take to move these visions from wishful thinking to reality? More than rhetoric, to be sure. But even the articulation of improbable objectives will have its impact. As documented in a recent book, Iran’s post-revolutionary experience demonstrates that the regime’s reliance on promises of economic gains has generated public expectations for effective and accountable governance. Now Iranians and Saudis have been told by their leaders—who happen to be officially infallible—that the time has come to transcend oil. What might happen if they believe it?

Renewable energy is an important source to tackle against climate change, as the latest IPCC report has pointed out. However, due to the existence of multiple market failures such as negative externalities of fossil fuels and knowledge spillovers of new technology, government subsidies are still needed to develop renewable energy, such as solar photovoltaic (PV) cells. In the United States, there have been various forms of subsidies for PV, varying from the federal level to the state level, and from the city level to the utility level. California, as the pioneer of solar PV development, has put forward the biggest state-level subsidy program for PV, the California Solar Initiative (CSI). The CSI has planned to spend around $2.2 Billion in 2007–2016 to install roughly 2 GW PV capacity, with the average subsidy level as high as $1.1/W. How to evaluate the cost-effectiveness and incentive pass-through of this program are the two major research questions we are pursing.

Our cost-effectiveness analysis is based on a constrained optimization model that we developed, where the objective is to install as much PV capacity as possible under a fixed budget constraint. Both the analytical and computational results suggest that due to a strong peer effect and the learning-by-doing effect, one can shift subsides from later periods to early periods so that the final PV installed capacity can be increased by 8.1% (or 32 MW). However, if the decision-maker has other policy objectives or constraints in mind, such as maintaining the policy certainty, then, the optimally calculated subsidy policy would look like the CSI.

As to the incentive pass-through question, we took a structural approach and in addition used the method of regression discontinuity (RD). While in general, the incentive pass-through rate depends on the curvature of the demand and supply curve and the level of market competition, our two estimations indicate that the incentive pass-through for the CSI program is almost complete. In other words, almost all of the incentive has been enjoyed by the customer, and the PV installers did not retain much. Based on the RD design, we observe that PV installers tend to consider the CSI incentive as exogenous to their pricing decision.

The relative good performance of the CSI in terms of both the cost-effectiveness and the incentive pass-through aspect are tightly related to its policy design and program management. International speaking, the biggest challenge for the design of any PV subsidy program is the quick running out of the budget, and in the end, it looks like customers are rushing for the subsidy. Such rushing behavior is a clear indication of higher-than-needed incentive levels. Due to the policy rigidity and rapid PV technological change, the PV subsidy policy may lag behind the PV cost decline; and as a result, rational customers could rush for any unnecessarily high subsidy.

Due to the high uncertainty and unpredictability of future PV costs, the CSI put forward a new design that links the incentive level change and the installed capacity goal fulfillment. Specifically, the CSI has designed nine steps to achieve its policy goal; at each step, there is a PV capacity goal that corresponds to an incentive level. Once the capacity goal is finished, the incentive level will decrease to the next lower level. Furthermore, to maintain the policy certainty, the CSI regulated that every step-wise change in the incentive level should not be higher than $0.45/W, nor smaller than $0.05/W, together with other three constraints.

A good subsidy policy not only requires flexible policy design to respond to fast-changing environment, but also demands an efficient program management system, digitalized if possible. For the CSI, the authority has contracted out a third-party to maintain a good database system for the program. Specifically, the database has documented in detail every PV system that customers requested. Key data fields include 22 important dates during the PV installation process, customers’ zip code, city, utility and county information, and various characteristics of the PV system such as price, system size, incentive, PV module and installer. All information is publicly available, which to some extent fills in the information gap held by customers and fosters the market competition among PV installers. For customers to receive the incentive, their PV systems have to pass the inspection of the local government, and also to be interconnected to the grid. On the supply side, the CSI has also certified and created a list of PV installers that every customer can choose from.

Although the CSI has ended in 2014 due to fast PV cost reduction starting from 2009, its experience has been transferred to other areas in the United States and in Europe. It is highly possible that other similar new technologies and products (e.g. the electric car and the battery) can adopt the CSI policy design, too. In summary, a good and successful policy may need to be simply, clear, credible, foreseeable, flexible, end-able, and incentive-compatible. The PV subsidy policy in China still has a long way to go when compared to the CSI.

What do Americans think about U.S. natural gas? 

The answer depends on who you ask. Presidential candidates, Washington think tank analysts, and ordinary citizens all give widely different answers to that question. In the United States, natural gas is sure to play an important role in the energy mix for the foreseeable future and has yielded several major economic, environmental, and health benefits in the short- and medium-term. Despite this, the image of natural gas has deteriorated in recent years, particularly within the environmental community. 

In a new policy brief, "Natural gas in the United States in 2016: Problem child and poster child," Tim Boersma discusses the various sentiments surrounding the debate over natural gas, analyzing the data supporting or refuting these varied points of view. Additionally, Boersma discusses the role that natural gas can play as a bridge fuel to a low-carbon economy, outlining a policy and research agenda for the utilization of natural gas going forward.

More than a decade after the start of the war in Afghanistan, America continues to face significant challenges in the Middle East. While news of U.S. struggles often dominate foreign policy discussions, Senior Fellow Bruce Riedel says it is important to remember that the United States is also making progress in the region. From the death of Osama bin Laden to an agreement on the use of Afghan military bases for U.S. counterterrorism operations, America is learning from its past mistakes and using these lessons to guide its response to the Arab Spring.
