CARICOM's Commercialization of energy efficiency programs and projects in the Caribbean.

As part of its mandate to promote resilient energy matrices region-wide, CARICOM has identified the promotion of investment into energy efficiency programs and projects as a priority action item.

On April 5th at 10.00am EST, the Caribbean Community (CARICOM) Secretariat and New Energy Events will co-host a webinar focused on new approaches to the commercialization of energy efficiency programs and projects in the Caribbean.

Confirmed panelists:

Jacob Corvidae, Manager, Rocky Mountain Institute

Kelly Tomblin, President & CEO, Jamaica Public Service Co.

Dr. Devon Gardner, Programme Manager, Energy, CARICOM

Joseph Williams, Sustainable Energy Advisor, Caribbean Development Bank

Despite the obvious potential for investment in energy efficiency across the Caribbean, the markets are yet to take off in any meaningful way. The unavailability of sustainable and affordable financing is widely recognized as the most significant hurdle to commercialization. The webinar will explore an emerging alignment of stakeholders around energy efficiency investments, and examine a number of innovative approaches to financing.

Topics will include:

• How do we introduce investment in energy efficiency into the mainstream?

• How do regional utilities look at investment in EE initiatives from a long-term ROI perspective? How can we align economic incentives to motivate utilities to invest in EE?

• What can we learn from the experience of other markets and other utilities? Hawaii, for example?

• What is the Integrated Utility Service (IUS) model? What can we learn from the initial experience in Fort Collins?

• How might utility-centric EE programs align with public sector and multilateral objectives and with what implication for the financing of EE programs?

• How do we de-risk EE investment?

• What are the opportunity costs associated with the inability of the current "market will deliver" philosophy to tap the regional EE potential?

• What are the key stakeholders - utilities, utility regulators, governments, multilaterals and private investors - prepared to do in order to deliver clean, efficient, reliable and cost-effective energy services to end-users? More

Renewable Energy After COP21: Nine issues for climate leaders to think about on the journey home

COP21 in Paris is over. Now it’s back to the hard work of fighting for, and implementing, the energy transition.

We all know that the transition away from fossil fuels is key to maintaining a livable planet. Several organizations have formulated proposals for transitioning to 100 percent renewable energy; some of those proposals focus on the national level, some the state level, while a few look at the global challenge. David Fridley (staff scientist of the energy analysis program at Lawrence Berkeley Laboratory) and I have been working for the past few months to analyze and assess many of those proposals, and to dig deeper into energy transition issues—particularly how our use of energy will need to adapt in a ~100 percent renewable future. We have a book in the works, titled Our Renewable Future, that examines the adjustments society will have to make in the transition to new energy sources. We started this project with some general understanding of the likely constraints and opportunities in this transition; nevertheless, researching and writing Our Renewable Future has been a journey of discovery. Along the way, we identified not only technical issues requiring more attention, but also important implications for advocacy and policy. What follows is a short summary—tailored mostly to the United States—of what we’ve learned, along with some recommendations.

1. We really need a plan; no, lots of them

Germany has arguably accomplished more toward the transition than any other nation largely because it has a plan—the Energiewende. This plan targets a 60 percent reduction in all fossil fuel use (not just in the electricity sector) by 2050, achieving a 50 percent cut in overall energy use through efficiency in power generation (fossil fueled power plants entail huge losses), buildings, and transport. It’s not a perfect plan, in that it really should aim higher than 60 percent. But it’s better than nothing, and the effort is off to a good start. Although the United States has a stated goal of generating 20 percent of its electricity from renewable sources by 2030, it does not have an equivalent official plan. Without it, we are at a significant disadvantage.

What would a plan do? It would identify the low-hanging fruit, show how resources need to be allocated, and identify needed policies. We would of course need to revise the plan frequently as we gained practical experience (as Germany is doing).

What follows are some components of a possible plan, based on work already done by many researchers in the United States and elsewhere; far more detail (with timelines, cost schedules, and policies) would be required for a fleshed-out version. It groups tasks into levels of difficulty; work would need to commence right away on tasks at all levels of difficulty, but for planning purposes it’s useful to know what can be achieved relatively quickly and cheaply, and what will take long, expensive, sustained effort.

Level One: The “easy” stuff

Nearly everyone agrees that the easiest way to kick-start the transition would be to replace coal with solar and wind power for electricity generation. That would require building lots of panels and turbines while regulating coal out of existence. Distributed generation and storage (rooftop solar panels with home- or business-scale battery packs) will help. Replacing natural gas will be harder, because gas-fired “peaking” plants are often used to buffer the intermittency of industrial-scale wind and solar inputs to the grid (see Level Two). More

Caribbean States 'lighting path' towards sustainable future, says UN chief in Barbados

"I want to salute Caribbean countries for taking on ambitious renewable energy targets. By 2020, for example, Barbados will be one of the world's top five leading users of solar energy on a per capita basis. You are lighting the path to the future,"


Secretary-General Ban Ki-moon My main message to you is to remain fully engaged and keep working with us to strengthen our partnership during this vital year for humanity. Together, we can build a better, more sustainable world, for all.said during a high-level symposium focused on sustainable development in the Caribbean.

This meeting was among the UN chief's first stops in Barbados, where later on Thursdayhe is expected to make opening remarks to the 2015 Caribbean Community (CARICOM) Summit, and where tomorrow, he will, among others, hold an interactive dialogue at the University of the West Indies.


"Twenty years ago, this very building was the site of the First Global Conference on Small Island Developing States that adopted the Barbados Programme of Action – the first compact between this group and the international community," he noticed


For small island developing States, Ban added, this space is "hallowed ground."

Encouraged by the presence of so many leaders of governments, regional and international organizations, the private sector, academia, and civil society, the Secretary-General highlighted the "continuing Caribbean commitment to put our world on a safer, more sustainable and equitable pathway," a few days from theThird International Conference on Financing for Development in Addis Ababa, Ethiopia.

"As leaders of some of the most vulnerable countries in the world, you don't need to be told that our planet is at grave risk. You are on the climate frontlines. You see it every day," he continued.

Convinced that sustainable development and climate change are "two sides of the same coin," the UN top official went on to say that this generation could be the first to end global poverty, and the last to prevent the worst impacts of global warming "before it is too late."


To get there, he underlined, the international community must make sure that the proposed sustainable development goals (SDGs) are "focused, financed and followed up – with real targets, real money and a real determination to achieve them."


Considering these goals as a sort of a "to-do list for people and the planet", Ban emphasized that it will take partnerships to make that happen. In that regard, he said, the Third International Conference on Small Islands Developing States in Samoa last year laid a pathway for collective action and success within the post-2015 development agenda.


But, as the world prepares for a new sustainability framework and the sustainable development goals, a number of critical partnership areas must be strengthened, in particular the need for capacity building; financing; access to technology; and improved data collection and statistics.

Member States also must continue working together to link the global agenda to regional agendas and to deepen regional integration and to address the "unique needs and vulnerabilities" of small island developing states and middle-income countries, such as the debt challenge.

"And we need to keep forging the way forward towards a low-carbon, climate-resilient development pathway that will benefit both people and the planet," the Secretary-General underlined.

He gave the assurance that, through the Green Climate Fund, and in working with world leaders, he will continue to insist that small islands and least developed countries are top funding priorities.


"My main message to you is to remain fully engaged and keep working with us to strengthen our partnership during this vital year for humanity. Together, we can build a better, more sustainable world, for all."

Later, in an address to an event on ending violence against women, the Secretary-General said the Caribbean has among the highest rates of sexual assault in the world. Three Caribbean countries are in the global top ten for recorded rapes. Moreover, he noted that in the eastern Caribbean, UNICEF estimates that child sexual abuse rates are between 20 and 45 per cent – meaning at least one in five precious children are affected. Most are girls who have no choice but to live close to their attacker.

"They desperately need our help. Too many women are afraid to seek help. One study showed that up to two thirds of all victims suffer without ever reporting the crime. I am outraged by this. Shame belongs to the perpetrators – not the victiWe have to change mindsets – especially among men," declared the UN chief.

In that light, he said he was proud to be the first man to sign onto the UN's HeForShecampaign, and he invited more men to take the HeForShe pledge.

"I encourage you to join UNICEF's End Violence global campaign. And every day, I count on all of you to work for true equality."


In the margins of the 36th meeting of the Conference of Heads of Government of the Caribbean Community in Barbados, the Secretary-General met with Prime Minister Freundel Stuart, and Minister for Foreign Affairs and Foreign Trade, Maxine McClean, of Barbados, a country he congratulated for its upcoming leadership of CARICOM.

The energy transition tipping point is here

In late February, Bloomberg finally addressed the most problematic issue in shale gas and tight oil wells: their incredible decline rates and diminishing prospects for drilling in the most-profitable "sweet spots" of the shale plays. I have documented that issue at length (for example, "Oil and gas price forecast for 2014," "Energy independence, or impending oil shocks?," "The murky future of U.S. shale gas," and my Financial Times critique of Leonardo Maugeri's widely heralded 2012 report).

The sources for the Bloomberg article are shockingly candid about the difficulties facing the shale sector, considering that their firms have been at the forefront of shale hype.

The vice president of integration at oil services giant Schlumberger notes that four out of every 10 frack clusters are duds. Geologist Pete Stark, a vice president of industry relations at IHS—yes, that IHS, where famous peak oil pooh-pooher Daniel Yergin is the spokesman for its CERA unit—actually said what we in the peak oil camp have been saying for years: "The decline rate is a potential show stopper after a while…You just can’t keep up with it."

The CEO of Superior Energy Services was particularly pithy: "We've drilled all the good stuff…These are very poor quality formations that I don't believe God intended for us to produce from the source rock." Source rocks, as I wrote last month, are an oil and gas "retirement party," not a revolution.

The toxic combination of rising production costs, the rapid decline rates of the wells, diminishing prospects for drilling new wells, and a drilling program so out of control that it caused a glut and destroyed profitability, have finally taken their toll.

Numerous operators are taking major write-downs against reserves. WPX Energy, an operator in the Marcellus shale gas play, and Pioneer Natural Resources, an operator in the Barnett shale gas play, each have announced balance sheet “impairments” of more than $1 billion due to low gas prices. Chesapeake Energy, Encana, Apache, Anadarko Petroleum, BP, and BHP Billiton have disclosed similar substantial reserves reductions. Occidental Petroleum, which has made the most significant attempts to frack California’s Monterey Shale, announced that it will spin off that unit to focus on its core operations—something it would not do if the Monterey prospects were good. EOG Resources, one of the top tight oil operators in the United States, recently said that it no longer expects U.S. production to rise by 1 million barrels per day (mb/d) each year, in accordance with my 2014 oil and gas price forecast.

Coal and nuclear

When I wrote “Why baseload power is doomed” and "Regulation and the decline of coal power" in 2012, the suggestion that renewables might displace baseload power sources like coal and nuclear plants was generally received with ridicule. How could "intermittent" power sources with just a few percentage points of market share possibly hurt the deeply entrenched, reliable, fully amortized infrastructure of power generation?

But look where we are today. Coal plants are being retired much faster than most observers expected. The latest projection from the U.S. Energy Information Administration (EIA) is for 60 gigawatts (GW) of coal-fired power capacity to be taken offline by 2016, more than double the retirements the agency predicted in 2012. The vast majority of the coal plants that were planned for the United States in 2007 have since been cancelled, abandoned, or put on hold, according to SourceWatch.

Nuclear power plants were also given the kibosh at an unprecedented rate last year. More nuclear plant retirements appear to be on the way. Earlier this month, utility giant Exelon, the nation’s largest owner of nuclear plants, warned that it will shut down nuclear plants if the prospects for their profitable operation don’t improve this year.

Japan has just announced a draft plan that would restart its nuclear reactors, but the plan is "vague" and, to my expert nose, stinks of political machinations. What we do know is that the country has abandoned its plans to build a next-generation "fast breeder" reactor due to mounting technical challenges and skyrocketing costs.

Grid competition

Nuclear and coal plant retirements are being driven primarily by competition from lower-cost wind, solar, and natural gas generators, and by rising operational and maintenance costs. As more renewable power is added to the grid, the economics continue to worsen for utilities clinging to old fossil-fuel generating assets (a topic I have covered at length; for example, "Designing the grid for renewables," "The next big utility transformation," "Can the utility industry survive the energy transition?" "Adapt or die - private utilities and the distributed energy juggernaut" and "The unstoppable renewable grid").

Nowhere is this more evident than in Germany, which now obtains about 25 percent of its grid power from renewables and which has the most solar power per capita in the world. I have long viewed Germany’s transition to renewables (see "Myth-busting Germany's energy transition") as a harbinger of what is to come for the rest of the developed world as we progress down the path of energy transition.

And what's to come for the utilities isn't good. Earlier this month, Reuters reported that Germany’s three largest utilities, E.ON, RWE, and EnBW are struggling with what the CEO of RWE called “the worst structural crisis in the history of energy supply.” Falling consumption and growing renewable power have cut the wholesale price of electricity by 60 percent since 2008, making it unprofitable to continue operating coal, gas and oil-fired plants. E.ON and RWE have announced intentions to close or mothball 15 GW of gas and coal-fired plants. Additionally, the three major utilities still have a combined 12 GW of nuclear plants scheduled to retire by 2020 under Germany’s nuclear phase-out program.

RWE said it will write down nearly $4 billion on those assets, but the pain doesn’t end there. Returns on invested capital at the three utilities are expected to fall from an average of 7.7 percent in 2013 to 6.5 percent in 2015, which will only increase the likelihood that pension funds and other fixed-income investors will look to exchange traditional utility company holdings for “green bonds” invested in renewable energy. The green bond sector is growing rapidly, and there's no reason to think it will slow down. Bond issuance jumped from $2 billion in 2012 to $11 billion in 2013, and the now-$15 billion market is expected to nearly double again this year.

A new report from the Rocky Mountain Institute and CohnReznick about consumers "defecting" from the grid using solar and storage systems concludes that the combination is a "real, near and present" threat to utilities. By 2025, according to the authors, millions of residential users could find it economically advantageous to give up the grid. In his excellent article on the report, Stephen Lacey notes that lithium-ion battery costs have fallen by half since 2008. With technology wunderkind Elon Musk's new announcement that his car company Tesla will raise up to $5 billion to build the world's biggest "Gigafactory" for the batteries, their costs fall even farther. At the same time, the average price of an installed solar system has fallen by 61 percent since the first quarter of 2010.

At least some people in the utility sector agree that the threat is real. Speaking in late February at the ARPA-E Energy Summit, CEO David Crane of NRG Energy suggested that the grid will be obsolete and used only for backup within a generation, calling the current system "shockingly stupid."

Non-hydro renewables are outpacing nuclear and fossil fuel capacity additions in much of the world, wreaking havoc with the incumbent utilities' business models. The value of Europe's top 20 utilities has been halved since 2008, and their credit ratings have been downgraded. According to The Economist, utilities have been the worst-performing sector in the Morgan Stanley index of global share prices. Only utilities nimble enough to adopt new revenue models providing a range of services and service levels, including efficiency and self-generation, will survive.

In addition to distributed solar systems, utility-scale renewable power plants are popping up around the world like spring daisies. Ivanpah, the world's largest solar "power tower" at 392 megawatts (MW), just went online in Nevada. Aura Solar I, the largest solar farm in Latin America at 30 MW, is under construction in Mexico and will replace an old oil-fired power plant. India just opened its largest solar power plant to date, the 130 MW Welspun Solar MP project. Solar is increasingly seen as the best way to provide electricity to power-impoverished parts of the world, and growth is expected to be stunning in Latin America, India and Africa.

Renewable energy now supplies 23 percent of global electricity generation, according to the National Renewable Energy Laboratory, with capacity having doubled from 2000 to 2012. If that growth rate continues, it could become the dominant source of electricity by the next decade.

Environmental disasters

Faltering productivity, falling profits, poor economics and increasing competition from power plants running on free fuel aren't the only problems facing the fossil-fuels complex. It has also been the locus of increasingly frequent environmental disasters.

On Feb. 22, a barge hauling oil collided with a towboat and spilled an estimated31,500 gallons of light crude into the Mississippi River, closing 65 miles of the waterway for two days.

More waterborne spills are to be expected along with more exploding trains as crude oil from sources like the Bakken shale seeks alternative routes to market while the Keystone XL pipeline continues to fight an uphill political battle. According to the Association of American Railroads, the number of tank cars shipping oil jumped from about 10,000 in 2009 to more than 230,000 in 2012, and more oil spilled from trains in 2013 than in the previous four decades combined.

Federal regulators issued emergency rules on Feb. 25 requiring Bakken crude to undergo testing to see if it is too flammable to be moved safely by rail, but I am not confident this measure will eliminate the risk. Light, tight oil from U.S. shales tends to contain more light molecules such as natural gas liquids than conventional U.S. crude grades, and is more volatile.

Feb. 11 will go down in history as a marquee bad day for fossil fuels, on which 100,000 gallons of coal slurry spilled into a creek in West Virginia; a natural gas well in Dilliner, Pa., exploded (and burned for two weeks before it was put out); and a natural gas pipeline ruptured and exploded in Tioga, ND. Two days later, another natural gas line exploded in the town of Knifely, Ky., igniting multiple fires and destroying several homes, barns, and cars. The same day, another train carrying crude oil derailed near Pittsburgh, spilling between 3,000 and 7,500 gallons of crude oil.

And don't forget the spill of 10,000 gallons of toxic chemicals used in coal processing from a leaking tank in West Virginia in early January, which sickened residents of Charleston and rendered its water supply unusable.

No return

At this point you may think, "Well, this is all very interesting, Chris, but why should we believe we've reached some sort of tipping point in energy transition?"

To which I would say, ask yourself: Is any of this reversible?

Is there any reason to think the world will turn its back on plummeting costs for solar systems, batteries, and wind turbines, and revert back to nuclear and coal?

Is there any reason to think we won't see more ruptures and spills from oil and gas pipelines?

What about the more than 1,300 coal-ash waste sites scattered across the United States, of which about half are no longer used and some are lacking adequate liners? How confident are we that authorities will suddenly find the will, after decades of neglect, to ensure that they'll not cause further contamination after damaging drinking water supplies in at least 67 instances so far, such that we feel confident about continuing to rely on coal power?

Like the disastrous natural gas pipeline that exploded in 2010 and turned an entire neighborhood in San Bruno, Calif., into a raging inferno, coal-ash waste sites are but one part of a deep and growing problem shot through the entire fabric of America: aging infrastructure and deferred maintenance. President Obama just outlined his vision for a $302 billion, four-year program of investment in transportation, but that's just a drop in the bucket, and it's only for transportation.

Is there any reason to think citizens will brush off the death, destruction, environmental contamination of these disasters—many of them happening in the backyards of rural, red-state voters—and not take a second look at clean power?

Is there any reason to believe utilities will swallow several trillion dollars worth of stranded assets and embrace new business models en masse? Or is it more likely that those that can will simply adopt solar, storage systems, and other measures that ultimately give them cheaper and more reliable power, particularly in the face of increasingly frequent climate-related disasters that take out their grid power for days or weeks?

Is there any reason to think the billions of people in the world who still lack reliable electric power will continue to rely on filthy diesel generators and kerosene lanterns as the price of oil continues to rise? Or are they more likely to adopt alternatives like the SolarAid solar lanterns, of which half a million have been sold across Africa in the past six months alone? (Here's a hint: Nobody who has one wants to go back to their kerosene lantern.) Founder Jeremy Leggett of SunnyMoney, who created the SolarAid lanterns, intends to sell 50 million of them across Africa by 2020.

Is there any reason to believe solar and wind will not continue to be the preferred way to bring power to the developing world, when their fuel is free and conventional alternatives are getting scarcer and more expensive?

Is there any reason a homeowner might not think about putting a solar system on his or her roof, without taking a single dollar out of his or her pocket, and using it to charge up an electric vehicle instead of buying gasoline?

Is there any reason to think that drilling for shale gas and tight oil in the United States will suddenly resume its former rapid growth rates, when new well locations are getting harder to find, investment by the oil and gas companies is being slashed, share prices are falling, reserves are getting taken off balance sheets and investors are getting nervous?

I don't think so. All of these trends have been developing for decades, and new data surfacing daily only reinforces them. More

Europe 24 Air Traffic

This data visualization of Air Traffic in Europe was created from real flight data. It shows the air traffic which flies on a typical summer day and highlights the intensity of the operation in Europe - an operation which runs 24x7x365.

NATS and the UK are at the heart of the operation. With Heathrow as the busiest international airport in Europe, and Gatwick as the busiest single runway airport in the world, the UK plays a key role in ensuring air traffic under our control in European airspace is as safe and efficient as it can be.

The question and the elephant in the skies is of course how much fossil fuel is burned and converted into carbon dioxide by aviation globally on a daily basis? For those of us that live on small low lying islands (SIDS) the outcome will be disasterous as our homes will eventually be submerged by rising sea level. Editor

Seychelles Grid Connected Rooftop Photovoltaic Systems

The Seychelles, like many Small Island Developing States (SIDS) is almost 100% reliant on imported oil for energy needs, which is a significant economic and budgetary cost, and is the single largest contributor of greenhouse gases in the country (based on emissions during the shipping process and in the burning of fuel to produce electricity).

Given that Seychelles is a tropical country receiving large amounts of sunshine, with an average 6.9 hours of sunshine per day, there is great potential to replace at least some of the current oil-generated (and polluting) electricity with solar energy systems. One opportunity with high economic, financial and environmental viability is the implementation of rooftop grid-connected PV systems. Current barriers to a more widespread utilization of PV systems in the Seychelles include market barriers, institutional and regulartory barriers, and technical barriers.

The objective of the project is to increase the use of PV systems as a sustainable means of generating electricity, thereby significantly reducing reliance on fossil fuel, through pilot projects for rooftop PV systems on all of the main and selected smaller islands, of the Seychelles. The identified barriers to the deployment, diffusion and transfer of solar PV systems will be addressed through the following project components: a) establishing a strategic policy and legal framework, b) strengthening technology support and delivery systems, and c) creating pilot PV projects.

ENERGY DARWINISM The Evolution of the Energy Industry

The global energy industry has been transformed in the last five years in ways and to an extent that few would have thought credible.

Of the $9.7 trillion of global investment in Power Generation, 71% will be in renewables or clean technologies.

The emergence of shale gas has transformed the U.S. energy market while Germany has seen some gas-fired power stations running for less than 10 days a year due to the impact of solar leading utility owners to issue profit warnings. Developed markets now spend more on renewable capital expenditures than they do on conventional generation, largely due to uncertainty over commodity pricing and likely future utilisation rates, while the legacy of Fukushima has seen Japan burning gas at $16-17/mmbtu while the U.S. basks in $3 shale, driving the introduction of the world’s most attractive solar subsidy scheme and catapulting Japan to be the world’s second largest solar market.

Conversely, the intermittency of renewables has led to the greater demand for the flexibility of gas-fired power plants in some markets. So, fuel and technology substitution is happening – and not just in developed markets. The shift in emerging markets is less marked, but is nonetheless there. The voracious appetite for power displayed by emerging markets will engender a higher level of new conventional generation (in particular coal), though gas is gradually taking demand from coal and renewables are forecast to represent 10% of new installed power generation capacity in China over the next two years. Despite these shifts, the analysis of individual fuel and technology cost curves – a key determinant in setting the market price – has continued largely on a standalone basis, with limited emphasis on the risks of substitution.

Accordingly, in this report we have combined the work of our alternative energy oil & gas, mining (coal), utility and commodity research teams to create an integrated energy cost curve, which allows us to assess the impact and risks of this substitutional change across all fuel and technology types. Importantly, this integrated curve looks at incremental energy demand and supply, meaning relatively small changes in the mix can have a material impact on the returns of projects, particularly those at the upper end of the cost curve.

Richard Branson Launches A Green Energy Plan For The Caribbean

In 1979, when Richard Branson bought the 74-acre Necker Island in the British Virgin Islands, he paid less than $300,000. It was untouched, undeveloped, inhabited only by birds and jungle critters. Back then, no one worried a wit about carbon emissions, ocean acidification, rising sea levels. To bring electricity to his island retreat Branson, like virtually everyone else on the small islands of the Caribbean, installed diesel generators.

Necker Island

As far as fuels go, diesel is hard to beat. It’s easy to transport and contains a lot of energy in a small volume. It’s already ubiquitous in the islands as fuel for boats. And it’s never been cleaner, with U.S. government standards limiting sulfur content to no more than 15 parts per million. For decades, diesel was simply the way to go.

But Branson wants to change that. Because running on diesel means that the cost of electricity on Caribbean islands averages about 50 cents per kwh, about five times what it is on the mainland United States.

In early February, Branson leveraged his star power to convene a three-day meeting of dignitaries from 13 Caribbean nations including the Virgin Island, St. Kitts & Nevis, Turks & Caicos and the Cayman Islands. While enjoying both Necker Island and Branson’s neighboring Moskito Island, they discussed the costs of powering their island homes and the economics of switching over to clean, green renewable energy.

Working with The Carbon War Room (an anti-carbon group he co-founded) as well as the energy experts at the Rocky Mountain Institute, Branson is promoting something called the 10 Island Renewable Challenge. The idea is to get the island nations of the Caribbean to switch away from diesel. The argument is simple: going carbon-free won’t just help keep the air clean and reduce greenhouse gases in the atmosphere — it will save lots of money too.

To help the cause, Carbon War Room and RMI have worked with the World Bank and the U.S. Overseas Private Investment Corporation to earmark $300 million for new renewable energy projects in the islands.

Necker Island will be the first to make that shift. Within three years Branson aims to be using solar and wind, with battery backup, to provide for 80% of Necker’s energy needs, with a long-term goal of 100%. Branson has contracted with NRG EnergyNRG Energy to build Necker’s renewable micro-grid.

“What we hope to do is use Necker as a test island to show how it can be done,” said Branson in a statement. “The only way we’re going to win this war is by creative entrepreneurship.”

Among the world’s CEOs and billionaires, Branson has real environmentalist cred. Sure the founder of Virgin Records, Virgin Airways, and now Virgin Galactic is responsible for millions of tons of carbon emissions over the years. But he’s been trying to make up for it. As early as 2008 his airline flew a Boeing Boeing 747 from London to Amsterdam on a low-carbon fuel made of babassu oil and coconut oil. He’s also a backer of the new solar-powered airplane SolarImpulse.

Jon Creyts, a managing director at the Rocky Mountain Institute, was in attendance at the conference, and shared with the group RMI’s research on just how much sense it makes for the islands to shift from diesel. According to Creyts, when you factor in the costs of fuel, transmission and capital investment, the average cost of electricity in the Caribbean ranges from 32 cents to 65 cents per kwh. That’s as much as five times what the average American pays for electricity. Most of that cost is in the diesel; a 1,000 kw diesel generator running at 100% capacity gulps about 70 gallons in an hour. That equates to .07 gallons per kwh. At current diesel prices in the Virgin Islands of $3.50 per gallon that comes out to 25 cents per kwh in diesel.

Compare that with the U.S. Energy Information Administration’s figures for the all-in costs of other generation methods. Gas turbines can do about 7 cents per kwh, offshore wind 22 cents, and solar photovoltaic 14 cents.

The increased costs of building in isolated locations might add a couple cents per kwh, but overall it’s hard to argue that the islands should stick with diesel. Even before Richard Branson’s new efforts, Aruba had worked with RMI and Carbon War Room to institute a green energy revolution. In recent years Aruba invested $300 million to build a 20-turbine wind farm rated at 30 mw that meets 20% of the island’s power needs. It replaced its old electric turbines with more efficient models, and is building a solar panel park. Since beginning its efforts in 2006 Aruba has reduced its imports of heavy fuel oil from 3,000 barrels per day to 1,700 barrels, saving some $50 million a year.

The U.S. Virgin Islands had taken tentative steps toward solar, signing long-term deals with solar developers to buy power from three systems with peak capacity of 18 mw. That will meet about 18% of the territory’s peak demand. A 20-year deal with Toshiba Toshiba will cost an average of 17 cents per kwh. The islands also require that all new construction use solar power for hot water heating.

It sounds good, but even on the islands, reality is a challenge. According to a study last year by the National Renewable Energy Laboratory, solar developers need an average of 10 acres of land to put up 1 mw of solar panels. That implies that if the U.S. Virgin Islands were to go totally solar and replace its two big oil-burning generators that put out about 100 mw around the clock, they would likely need at least 1,500 acres of land (or roofs) covered in panels, a bunch of wind turbines to provide power at night, plus some sort of ingenious energy storage system smooth out the peaks. That could be doable on St. Croix, which consists of about 53,000 acres and the 1,500-acre Hovensa oil storage terminal on its south side. A 1,100-acre chunk of land adjacent to the terminal is now in process of being cleaned up and redeveloped.

An even better idea for the very long term is for these islands to tap their enormous and endless domestic energy opportunity: geothermal. Most of the islands in the eastern Caribbean were formed by volcanic action. The volcano on Montserrat erupted violently in 1997, killing 19. Because they are located close to the boundaries of two tectonic plates, the islands have plenty of natural volcanic heat that they could tap at relatively shallow depths. Already Iceland Drilling Company, based in the world’s capital of geothermal energy, is reportedly working on exploratory geothermal projects in Dominica and Montserrat. Projects are also being drawn up for Nevis and St. Vincent.

In time each of these islands could be powered by steam turbines running on virtually endless supplies of cheap energy harnessed from the Earth’s own internal furnace.

But solar, wind and geothermal are all expensive. Another part of the challenge, says Creyts, who was a McKinsey consultant before joining RMI, is that most of the Caribbean islands have pretty lackluster credit ratings and not much borrowing capacity. Indeed, Jamaica, St Kitts-Nevis, Grenada, Barbados and Antigua and Barbuda all have public debt loads approaching or surpassing 100% of GDP. That’s why it was so vital to get the World Bank and OPIC on board to help arrange low-cost financing.

There’s no shortage of potential projects for the islands to pursue, with energy-hungry hotels, hospitals and schools offering the lowest-hanging fruit. Naturally, there’s plenty of corporate partners ready to help the islands make the shift. Executives from Philips, Johnson Controls, Sungevity, Vestas and NRG were present at the Necker Island retreat.

There’s some incentive for these island nations to think about moving a little quicker in their renewables plans. Many Caribbean nation’s have joined the PetroCaribe pact created by Venezuela’s late President Hugo Chavez, whereby Venezuela has for years sent them discounted oil. Though Chavez’ successor Nicolas Maduro has continued the oil discounts, there is concern that amid Venezuela’s slow-motion economic collapse the largesse will soon end, forcing the islands to pay more on the world market.

Renewable, carbon-free energy doesn’t yet make economic sense in the most densely inhabited parts of the world that are already well served by reliable energy sources. But islands like these represent a motivated laboratory of energy evolution. In time, the lessons learned in the islands will be ripe for application across the other energy-starved corners of the world. More
