Technically, all of the Star Wars films occur a long time ago in a galaxy far, far away, but there are countless gadgets featured in the films that human beings in this galaxy can find here on Earth. Here are a handful of gadgets you will see this weekend when the seventh Star Wars film, "The Force Awakens," blasts into theaters.

Drone surveillance

The evil Galactic Empire has long employed drones and machines to do their dirty work. Way back when the empire was just a glint in Darth Sidious' eyes, his merciless apprentice Darth Maul used autonomous drones to search the desert landscape of Tatooine for fugitive Jedi. Later, when Darth Vader tirelessly searched the galaxy for Luke Skywalker and the Rebel Alliance, he sent similar autonomous drones to countless worlds such as the ice planet Hoth.

Sure, the Empire may call them droids, but on the planet Earth these instruments are essentially remote drones you might see flying in cities or around your neighborhood. In the U.S. the use of unmanned drones to aid law enforcement is on the cutting edge of technology and sparks a spirited debate among privacy advocates. Should fear law enforcement as we would a Sith lord and thus burden them with a warrant-based, technology-centric approach to drone surveillance that might curtail the beneficial use of drones?

Gregory McNeal wrote last year in a Brookings report that a property rights-centric approach with limits on surveillance would best appease privacy advocates and law enforcement, enabling drones to protect privacy in ways even manned surveillance can't achieve. By crafting simple, duration based surveillance legislation, law enforcement would only be permitted to surveil a person for a limited amount of time. Additionally, data retention guidelines could limit the amount of time that surveillance would be accessible to law enforcement.

"Legislators should reject alarmist calls that suggest we are on the verge of an Orwellian police state," McNeal writes, as privacy advocates almost always invoke the the novel 1984 when technology makes surveillance more widespread and pervasive.

As McNeal points out, the police state is hardly as nefarious as Darth Vader, so sensible legislation may be enough in this case to keep law enforcement from falling to the dark side.

Holography

In the first Star Wars film, Princess Leia recorded a short holographic message for Obi-Wan Kenobi asking for his help delivering the Death Star plans to the Rebel Alliance. The droid R2-D2 recorded the message almost as succinctly as many of use record short videos on our cell phone. But when can we expect to send and receive holographic messages ourselves?

Barring some laughable election night hologram shenanigans on CNN, there have been some notable uses of holography in this galaxy. In 2012, the late rapper Tupac Shakur took the stage at the Coachella Festival with contemporaries Snoop Dogg and Dr. Dre. At the 2014 Billboard Music Awards, Michael Jackson performed on stage—five years after his death. These holograms were made possible by artful projections and reflections, creating convincing illusions suitable only for crowded concert halls. The technology is especially popular in South Korea where K-Pop performers regularly "perform" at virtual concerts to adoring fans.

But a bona fide hologram? Researchers at Swinburne University this year used lasers and a specialized graphene mesh to project 3D objects in the air very much like you would see in Star Wars. As TIME Magazine reported, "It’s not quite Princess Leia-quality, and researchers say it has a long way to go before commercialization, but it’s a step."

BB-8 Droid

Since the first teaser for the new Star Wars films, fans have had questions about the new droid character BB-8. Rather than resort to computer animation to bring the droid to life, director J.J. Abrams and Lucasfilm designers sought to produce a live prop that could portray the droid on film.

The filmmakers demoed the droid on stage at Comic Con to the roar of audience applause and delight—"It was the first official confirmation that BB-8 was not a CG creation, but rather, a practical effect."

The use of practical effects in "The Force Awakens" is a return-to-form for the filmmakers who have shunned the special effects and digital artistry of the Star Wars prequel trilogies and instead embraced the kinds of practical effects and puppetry that made the original trilogy so beloved.

The droid BB-8 even has a cousin here on Earth—the robotic ball toy Sphero. Inventors Ian Bernstein and Adam Wilson have adapted their smartphone-controlled spherical toy into a BB-8 toy that performs many of the same practical effects the screen version of BB-8 does in "The Force Awakens."

As the new sequel trilogy continues, filmmakers are sure to wow audiences with amazing technologies—some we may even recognize from planet Earth.

An American drone strike that killed leader of the Afghan Taliban Mullah Akhtar Mohammed Mansour may seem like a fillip for the United States’ ally, the embattled government of Afghanistan’s President Ashraf Ghani. But as Vanda Felbab-Brown writes in a new op-ed for The New York Times, it is unlikely to improve Kabul’s immediate national security problems—and may create more difficulties than it solves.

The White House has argued that because Mansour became opposed to peace talks with the Afghan government, removing him became necessary to facilitate new talks. Yet, as Vanda writes in the op-ed, “the notion that the United States can drone-strike its way through the leadership of the Afghan Taliban until it finds an acceptable interlocutor seems optimistic, at best.”

[T]he notion that the United States can drone-strike its way through the leadership of the Afghan Taliban until it finds an acceptable interlocutor seems optimistic, at best.

Mullah Mansour's death does not inevitably translate into substantial weakening of the Taliban's operational capacity or a reprieve from what is shaping up to be a bloody summer in Afghanistan. Any fragmentation of the Taliban to come does not ipso facto imply stronger Afghan security forces or a reduction of violent conflict. Even if Mansour's demise eventually turns out to be an inflection point in the conflict and the Taliban does seriously fragment, such an outcome may only add complexity to the conflict. A lot of other factors, including crucially Afghan politics, influence the capacity of the Afghan security forces and their battlefield performance.

Nor will Mansour’s death motivate the Taliban to start negotiating. That did not happen when it was revealed last July’s the group’s previous leader and founder, Mullah Mohammad Omar, had died in 2013. To the contrary, the Taliban’s subsequent military push has been its strongest in a decade—with its most violent faction, the Haqqani network, striking the heart of Kabul. Mansour had empowered the violent Haqqanis following Omar’s death as a means to reconsolidate the Taliban, and their continued presence portends future violence. Mansour's successor, Mawlawi Haibatullah Akhundzada, the Taliban’s former minister of justice who loved to issue execution orders, is unlikely to be in a position to negotiate (if he even wants to) for a considerable time as he seeks to gain control and create legitimacy within the movement.

The United States has sent a strong signal to Pakistan, which continues to deny the presence of the Afghan Taliban and the Haqqani network within its borders. Motivated by a fear of provoking the groups against itself, Pakistan continues to show no willingness to take them on, despite the conditions on U.S. aid.

Disrupting the group’s leadership by drone-strike decapitation is tempting militarily. But it can be too blunt an instrument, since negotiations and reconciliation ultimately depend on political processes. In decapitation targeting, the U.S. leadership must think critically about whether the likely successor will be better or worse for the counterinsurgency endgame.

Rooftop solar is booming in U.S. cities.

One of the most exciting infrastructure developments within metropolitan America, the installation of over a million solar photovoltaic (PV) systems in recent years, represents nothing less than a breakthrough for urban sustainability — and the climate.

Prices for solar panels have fallen dramatically. Residential solar installations surged by 66 percent between 2014 and 2015 helping to ensure that solar accounted for 30 percent of all new U.S. electric generating capacity. And for that matter, recent analyses conclude that the cost of residential solar is often comparable to the average price of power on the utility grid, a threshold known as grid parity.

So, what’s not to like? Rooftop solar is a total winner, right?

Well, not quite: The spread of rooftop solar has raised tricky issues for utilities and the public utilities commissions (PUCs) that regulate them. 

Specifically, the proliferation of rooftop solar installations is challenging the traditional utility business model by altering the relationship of household and utility—and not just by reducing electricity sales. In this respect, the solar boom has prompted significant debates in states like New York and California about the best rates and policies to ensure that state utility rules and rates provide a way for distributed solar to flourish even as utilities are rewarded for meeting customer demands. Increasingly, this ferment is leading to thoughtful dialogues aimed at devising new forms of policy and rate design that can—as in New York—encourage distributed energy resources (DERs) while allowing for distribution utilities to adapt to the new era.

However, in some states, the ferment has prompted a cruder set of backlashes. Most pointedly, some utilities contend that the “net-metering” fees paid to homeowners with rooftop installations for excess solar power they send back to the grid unfairly transfer costs to the utilities and their non-solar customers.

And so in a number of states, utility interests have sought to persuade state regulators to roll back net-metering provisions, arguing they are a net cost to the overall electricity system.  Most glaringly, the local utility in Nevada successfully wielded the cost-shift theory last winter to get the Nevada Public Utilities Commission to drastically curtail the state’s net-metering payments, prompting Solar City, Sunrun, and Vivint Solar—the state’s three largest providers of rooftop panels—to leave the Nevada market entirely. The result: New residential solar installation permits plunged 92 percent in Nevada in the first quarter of 2016.

All of which highlights a burning question for the present and future of rooftop solar: Does net metering really represent a net cost shift from solar-owning households to others? Or does it in fact contribute net benefits to the grid, utilities, and other ratepayer groups when all costs and benefits are factored in? As to the answer, it’s getting clearer (even if it’s not unanimous). Net metering — contra the Nevada decision — frequently benefits all ratepayers when all costs and benefits are accounted for, which is a finding state public utility commissions, or PUCs, need to take seriously as the fight over net metering rages in states like Arizona, California, and Nevada.  Regulators everywhere need to put in place processes that fairly consider the full range of benefits (as well as costs) of net metering as well as other policies as they set and update the policies, regulations, and tariffs that will play a critical role in determining the extent to which the distributed solar industry continues to grow.

Fortunately, such cost-benefit analyses have become an important feature of state rate-setting processes and offer important guidance to states like Nevada.  So what does the accumulating national literature on costs and benefits of net metering say?  Increasingly it concludes— whether conducted by PUCs, national labs, or academics — that the economic benefits of net metering actually outweigh the costs and impose no significant cost increase for non-solar customers.  Far from a net cost, net metering is in most cases a net benefit—for the utility and for non-solar rate-payers.

Of course, there are legitimate cost-recovery issues associated with net metering, and they vary from market to market. Moreover, getting to a good rate design, which is essential for both utility revenues and the growth of distributed generation, is undeniably complicated.  If rates go too far in the direction of “volumetric energy charges”—charging customers based on energy use—utilities could have trouble recovering costs when distributed energy sources reach higher levels of penetration. On the other hand, if rates lean more towards fixed charges—not dependent on usage—it may reduce incentives for customers to consider solar and other distributed generation technologies.  

Moreover, cost-benefit assessments can vary due to differences in valuation approach and methodology, leading to inconsistent outcomes. For instance, a Louisiana Public Utility Commission study last year found that that state’s net-metering customers do not pay the full cost of service and are subsidized by other ratepayers. How that squares with other states’ analyses is hard to parse.

Nevertheless, by the end of 2015, regulators in at least 10 states had conducted studies to develop methodologies to value distributed generation and net metering, while other states conducted less formal inquiries, ranging from direct rate design or net-metering policy changes to general education of decisionmakers and the public. And there is a degree of consensus.  What do the commission-sponsored analyses show? A growing number show that net metering benefits all utility customers:

• In 2013 Vermont’s Public Service Department conducted a study that concluded that “net-metered systems do not impose a significant net cost to ratepayers who are not net-metering participants.” The legislatively mandated analysis deemed the policy a successful component of the state’s overall energy strategy that is cost effectively advancing Vermont’s renewable energy goals.

• In 2014 a study commissioned by the Nevada Public Utility Commission itself concluded that net metering provided $36 million in benefits to all NV Energy customers, confirming that solar energy can provide cost savings for both solar and non-solar customers alike. What’s more, solar installations will make fewer costly grid upgrades necessary, leading to additional savings. The study estimated a net benefit of $166 million over the lifetime of solar systems installed through 2016. Furthermore, due to changes to utility incentives and net-metering policies in Nevada starting in 2014, solar customers would not be significantly shifting costs to other ratepayers.

• A 2014 study commissioned by the Mississippi Public Services Commission concluded that the benefits of implementing net metering for solar PV in Mississippi outweigh the costs in all but one scenario. The study found that distributed solar can help avoid significant infrastructure investments, take pressure off the state's oil and gas generation at peak demand times, and lower rates. (However, the study also warned that increased penetrations of distributed solar could lead to lower revenues for utilities and suggested that the state investigate Value of Solar Tariffs, or VOST, and other alternative valuations to calculate the true cost of solar.)

• In 2014 Minnesota’s Public Utility Commission approved a first-ever statewide “value of solar” methodology which affirmed that distributed solar generation is worth more than its retail price and concluded that net metering undervalues rooftop solar. The “value of solar” methodology is designed to capture the societal value of PV-generated electricity. The PUC found that the value of solar was at 14.5 cents per kilowatt hour (kWh)—which was 3 to 3.5 cents more per kilowatt than Xcel's retail rates—when other metrics such as the social cost of carbon, the avoided construction of new power stations, and the displacement of more expensive power sources were factored in.

• Another study commissioned by the Maine Public Utility Commission in 2015 put a value of $0.33 per kWh on energy generated by distributed solar, compared to the average retail price of $0.13 per kWh — the rate at which electricity is sold to residential customers as well as the rate at which distributed solar is compensated. The study concludes that solar power provides a substantial public benefit because it reduces electricity prices due to the displacement of more expensive power sources, reduces air and climate pollution, reduces costs for the electric grid system, reduces the need to build more power plants to meet peak demand, stabilizes prices, and promotes energy security. These avoided costs represent a net benefit for non-solar ratepayers.

These generally positive PUC conclusions about the benefits of net metering have been supported by research done by a national lab and several think tanks. Important lab research has examined how substantially higher adoption of distributed resources might look.

In a forward-looking analysis of the financial impacts of net-metered energy on utilities and ratepayers, Lawrence Berkeley National Lab found that while high use of net-metered solar generation may decrease utility shareholders' earnings, it will have a "relatively modest" impact on ratepayers. The report examined solar penetration levels that are "substantially higher than [those that] exist today" — 10 percent compared to today's 0.2 percent — and concluded that “even at penetration levels significantly higher than today, the impacts of customer-sited PV on average retail rates may be relatively modest." The report further said that utilities and regulators "may have sufficient time to address concerns about the rate impacts of PV in a measured and deliberate manner"

Similarly, a growing number of academic and think tank studies have found that solar energy is being undervalued and that it delivers benefits far beyond what solar customers are receiving in net-metering credits:

• For instance, a review of 11 net metering studies by Environment America Research and Policy Center has found that distributed solar offers net benefits to the entire electric grid through reduced capital investment costs, avoided energy costs, and reduced environmental compliance costs. Eight of the 11 studies found the value of solar energy to be higher than the average local residential retail electricity rate: The median value of solar power across all 11 studies was nearly 17 cents per unit, compared to the nation’s average retail electricity rate of about 12 cents per unit.

• A 2015 cost-benefit study of net metering in Missouri by the Missouri Energy Initiative found that even accounting for increased utility administrative costs and the shifting of some fixed expenses, net metering is a net benefit for all customers regardless of whether they have rooftop solar. The study used values for two kinds of costs and two benefits and concluded that net metering’s “net effect” is positive. The typical solar owner pays only 20 percent less in fixed grid costs and costs the utility an estimated $187 per interconnection. Meanwhile, solar owners benefit the system through reduced emissions and energy costs.

• Likewise, a study by Acadia Center found the value of solar to exceed 22 cents per kWh of value for Massachusetts ratepayers through reduced energy and infrastructure costs, lower fuel prices, and lowering the cost of compliance with the Commonwealth's greenhouse gas requirements. This value was estimated to exceed the retail rate provided through net metering.

• In yet another study, researchers at the University at Albany, George Washington University, and Clean Power Research have found that solar installations in New York deliver between 15 and 40 cents per kWh to ratepayers. The study noted that these numbers provide economic justification for the existence of incentives that transfer value from those who benefit from solar electric generation to those who invest in solar electric generation.

In short, while the conclusions vary, a significant body of cost-benefit research conducted by PUCs, consultants, and research organizations provides substantial evidence that net metering is more often than not a net benefit to the grid and all ratepayers.

As to the takeaways, they are quite clear: Regulators and utilities need to engage in a broader and more honest conversation about how to integrate distributed-generation technologies into the grid nationwide, with an eye toward instituting a fair utility-cost recovery strategy that does not pose significant challenges to solar adoption.

From the state PUCs’ perspective, until broad changes are made to the increasingly outdated and ineffective standard utility business model, which is built largely around selling increasing amounts of electricity, net-metering policies should be viewed as an important tool for encouraging the integration of renewable energy into states’ energy portfolios as part of the transition beyond fossil fuels. To that end, progressive regulators should explore and implement reforms that arrive at more beneficial and equitable rate designs that do not prevent solar expansion in their states. The following reforms range from the simplest to the hardest:

• Adopt a rigorous and transparent methodology for identifying, assessing, and quantifying the full range of benefits and costs of distributed generation technologies. While it is not always possible to quantify or assess sources of benefits and costs comprehensively, PUCs must ensure that all cost-benefit studies explicitly decide how to account for each source of value and state which ones are included and which are not. Currently methodological differences in evaluating the full value of distributed generation technologies make comparisons challenging. States start from different sets of questions and assumptions and use different data. For instance, while there is consensus on the basic approach to energy value estimation (avoided energy and energy losses via the transmission and distribution system), differences arise in calculating other costs and benefits, especially unmonetized values such as financial risks, environmental benefits, and social values. In this regard, the Interstate Renewable Energy Council’s “A Regulator’s Guidebook: Calculating the Benefits and Costs of Distributed Solar Generation” and the National Renewable Energy Laboratory’s “Methods for Analyzing the Benefits and Costs of Distributed Photovoltaic Generation to the U.S. Electric Utility System” represent helpful resources for identifying norms in the selection of categories, definitions, and  methodologies to measure various benefits and costs.

• Undertake and implement a rigorous, transparent, and precise “value of solar” analytic and rate-setting approach that would compensate rooftop solar customers based on the benefit that they provide to the grid. Seen as an alternative to ‘traditional’ net-metering rate design, a “value of solar” approach would credit solar owners for (1) avoiding the purchase of energy from other, polluting sources; (2) avoiding the need to build additional power plant capacity to meet peak energy needs; (3) providing energy for decades at a fixed prices; and (4) reducing wear and tear on the electric grid. While calculating the “value of solar” is very complex and highly location-dependent, ultimately PUCs may want to head toward an approach that accurately reflects all benefits and costs from all energy sources. Value of solar tariffs are being used in Austin, Texas (active use) and Minnesota (under development).

• Implement a well-designed decoupling mechanism that will encourage utilities to promote energy efficiency and distributed generation technologies like solar PV, without seeing them as an automatic threat to their revenues. As of January 2016, 15 states have implemented electric decoupling and eight more are considering it. Not surprisingly, it is states that have not decoupled electricity (such as Nevada) that are fighting net metering the hardest. Typically, decoupling has been used as a mechanism to encourage regulated utilities to promote energy efficiency for their customers. However, it can also be used as a tool to incentivize net metering by breaking the link between utility profits and utility sales and encouraging maximum solar penetration. Advocates of decoupling note that it is even more effective when paired with time-of-use pricing and minimum monthly billing.

• Move towards a rate design structure that can meet the needs of a distributed resource future. A sizable disconnect is opening between the rapidly evolving new world of distributed energy technologies and an old world of electricity pricing. In this new world, bundled, block, “volumetric” pricing—the most common rate structure for both residential and small commercial customers—can no longer meet the needs of all stakeholders. The changing grid calls, instead, for new rate structures that respond better to the deployment of new grid technologies and the proliferation of myriad distributed energy resources, whether solar, geothermal, or other.  A more sophisticated rate design structure, in this regard, would take into consideration three things: (1) the unbundling of rates to specifically price energy, capacity, ancillary services,  and so on; (2) moving from volumetric bloc rates to pricing structures that recognize the  variable time-based value of electricity generation and consumption (moving beyond just peak versus off-peak pricing to  fully real-time pricing); and (3) moving from pricing that treats all customers equally to a pricing structure that more accurately compensates for unique, location-specific and technology specific values.

• Move towards a performance-based utility rate-making model for the modern era. Performance based regulation (PBR) is a different way of structuring utility regulation designed to align a utility’s financial success with its ability to deliver what customers and society want. Moving to a model that pays the utility based on whether it achieves quantitatively defined outcomes (like system resilience, affordability, or distributed generation integration) can make it profitable for them to pursue optimal grid solutions to meet those outcomes. The new business model would require the PUC and utilities to make a number of changes, including overhauling the regulatory framework, removing utility incentives for increasing capital assets and kilowatt hours sold, and replacing those incentives with a new set of performance standard metrics such as reliability, safety, and demand-side management. New York’s Reforming the Energy Vision  proceeding is the most high-profile attempt in the country to implement a PBR model.

Options also exist for utilities to address the challenges posed by net metering:

• Utilities, most notably, have the opportunity to adjust their existing business models by themselves owning and operating distributed PV assets (though not to the exclusion of other providers).  On this front, utilities could move to assemble distributed generation systems, such as for rooftop solar, and sell or lease them to homeowners. In this regard, utilities have an advantage over third-party installers currently dominating the residential rooftop solar industry due to their proprietary system knowledge, brand recognition, and an existing relationship with their customers. Utilities in several states such as Arizona, California, and New York are investigating or have already invested in the opportunity.

• Furthermore, utilities can also push the envelope on grid modernization by investing in a more digital and distributed power grid that enables interaction with thousands of distributed energy resources and devices.

Ultimately, distributed solar is here to stay at increasing scale, and so state policies to support it have entered an important new transitional phase. More and more states will now likely move to update their net-metering policies as the cost of solar continues to drop and more homeowners opt to install solar panels on their homes.

As they do that, states need to rigorously and fairly evaluate the costs and benefits posed by net metering, grid fees, and other policies to shape a smart, progressive regulatory system that works for all of the stakeholders touched by distributed solar.

Utilities should have a shot at fair revenues and adequate ratepayers. Solar customers and providers have a right to cost-effective, reliable access to the grid. And the broader public should be able to expect a continued solar power boom in U.S. regions as well as accelerated decarbonization of state economies. All of which matters intensely. As observes the North Carolina Clean Energy Technology Center and Meister Consultants Group: “How key state policies and rates are adapted will play a significant role in determining the extent to which the [solar PV] industry will continue to grow and in what markets.”

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.

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.

The increasing diversification of news media—from online versions of major newspapers to political bloggers, to 24-hour cable news to social media—plus the profession’s changing economics have caused the balance of power between political reporters and presidential candidates to change. Stephen Hess, senior fellow emeritus, says our very good, well-trained reporters are “almost dangerous” to presidential candidates who are trying to stay on message. Thus, says Hess, the way the press covers campaigns has changed as well, and not for the better.

Senior Fellows Fiona Hill and Clifford G. Gaddy discuss their book, Mr. Putin: Operative in the Kremlin in a five part podcast series.

In the book, Hill and Gaddy write that Russian President Vladmir Putin’s style of rule is influenced by his identities as a Statist, a Man of History, a Free Marketeer, a Survivalist, an Outsider, and a Case Officer; these are distinct personalities, they note, that interact and affect policy decisions. On February 6, the Center on the United States and Europe at Brookings hosted an event for the launch of Mr. Putin with a discussion featuring the authors.
