Three years after Hurricane Katrina left broad tracts of Gulf Coast states without power, Hurricane Gustav delivered winds of more than 110 mph to the same region, knocking power out for more than a million customers, a number that continued to grow as evening fell.

With more than 780,000 customers out of power, almost all of them in Louisiana where the company has 1.2 million customers, Entergy Corp. said restoring electricity will rival the scale and difficulty of Katrina.

It is the third greatest number of outages in Entergy's 95-year history, only topped by the 1.1 million customers who lost power during Katrina and 800,000 customers who lost power a few weeks later when Hurricane Rita struck.

Nearly all of the outages were in Louisiana with smaller numbers of customers losing power in the states east of Louisiana. The storm was expected to push west toward Texas, where the wind was beginning to accelerate and the rain had just begun.

"It's not as strong as originally projected and that's good news," said Entergy spokesman Mike Burns. "But we are experiencing extremely significant damage in areas."

Power, though, was already being restored. Entergy said nearly 30,000 customers in New Orleans already have been brought back online. The company said it did not know how long it would take to restore power to the rest of the customers.

Cleco Corp., which has 273,000 customers in the state, said about 185,000 were without power and those outages were also spreading. Dixie Electric Membership Corp. reported on its Web site that 94,000 customers were without power.

Burns said 9,000 Entergy personnel, contractors and hardhats from other utilities were on standby, waiting for the worst of the storm to pass before they could begin to assess the damage.

Entergy said 134 transmission lines and 78 substations were out of service. Its nuclear plant near New Orleans was shutdown in anticipation of heavy winds.

It was not clear how or if the outages would affect the oil refineries that dot the coast.

In southeast Texas, hammered by Rita that struck right after Katrina in 2005, Entergy Texas officials were hopeful that the storm would continue to weaken.

"It's turning out to be less than what we had anticipated," said Joe Domino, Entergy Texas' president and chief executive.

Further east, Mississippi Power reported about 8,000 customers were without power and other Southern Co. utilities in Alabama and the Florida Panhandle reported outages totaling about 8,000.

"I think rebuilding and strengthening our distribution and transmission system over the past two seasons since Katrina hopefully has aided in minimizing the impact of Gustav," Mississippi Power spokeswoman Cindy Duvall said.

In April, Louisiana regulators approved a $1 billion plan from two units of Entergy to cover hurricane repair costs from Katrina and Rita in 2005 and set up a storm reserve fund. Entergy has received permission to pass along the costs to customers.

One of Entergy's utilities, Entergy New Orleans filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code in October 2005. The company emerged 20 months later with a plan that paid off all creditors. The utility also received $200 million in federal funding for part of its storm recovery costs.

Meanwhile, telecommunications companies said they too were prepared for outages.

They advised customers that text messaging has a greater success rate in getting through network during high-usage periods versus voice calls. They asked that phone calls should be kept short.

Gulf Power to Provide One-Time Bill Decrease of 40%

Gulf Power 40% One-Time Bill Decrease approved by the Florida Public Service Commission delivers a May fuel credit and COVID-19 relief, cutting residential and business costs across rate classes while supporting budgeting and energy savings.

 

Key Points

PSC-approved fuel credit cutting May electric bills about 40% for homes and 40-55% for businesses as COVID-19 relief.

✅ One-time May fuel credit on customer bills

✅ Residential cut ~40%; business savings 40-55% by rate class

✅ Online tools show daily usage and projected bill

 

Gulf Power announced that the Florida Public Service Commission unanimously approved its request to issue a one-time decrease of approximately 40% for the typical residential customer bill beginning May 1, similar to recent Georgia Power bill reductions seen elsewhere. Business customers will also see a significant one-time decrease of approximately 40-55% in May, depending on usage and rate class.

"We are pleased that the Florida Public Service Commission has approved our request to deliver this savings to our customers when they need it most. We felt that this was the right thing to do, especially during times like these," said Gulf Power President Marlene Santos. "Our customers and communities now more than ever count on the reliable and affordable energy we deliver, and we are pleased that May bills will reflect this additional, significant savings for our customers."

In Florida, fuel savings are typically refunded to customers over the remainder of the year to provide level, predictable bills. However, given the emergent and significant financial challenges facing many customers due to COVID-19, Gulf Power instead sought approval to give customers the total annual savings in their May bill, similar to a lump-sum electricity credit approach, which will be reflected as a line-item fuel credit on their May statement.

New tools to help save energy and money

Many customers are working from home and, in general, staying at home more. More time and extra people in the home will likely increase power usage, which could lead to higher monthly bills.

Gulf Power recently added new tools to our customers' online account portal to help them better understand and manage their energy usage, including their monthly projected bill amount and a breakdown of daily energy usage, which is available for most residential customers*. Customers can now see their previous day's energy usage using their online account portal to help them more easily understand how their previous day's activities impacted energy usage, allowing them to quickly make adjustments to keep bills low. The new projected bill feature is a valuable tool to assist customers in budgeting for their next month's energy bill.

Additional energy-saving tips that can be implemented with no additional cost or equipment are also available. As always, Gulf Power's free online Energy Checkup tool will provide customers with a customized report based on their home's actual energy use.

Helping customers pay their bills

Gulf Power has a long history of working with its customers during difficult times, including periods of pandemic-related energy insecurity, and will continue to do so. Gulf Power encourages customers that are having difficulty paying their energy bill to visit GulfPower.com/help to view available resources that can provide assistance to qualifying customers.

Customers are encouraged to pay their electric bill balance each month to avoid building up a large balance, which they will continue to bear responsibility for. Gulf Power will work with the customer's personal situation and assist with a solution, similar to how utilities in Texas have waived fees during this period, to help customers fulfill their personal responsibility for their Gulf Power balance.

Those who can afford or want to help others who may need assistance with their energy bill can make a donation to Project SHARE in your online customer portal. Project SHARE donations are added to a customer's monthly bill and all contributions are distributed to local offices of The Salvation Army. Customers in need of utility bill assistance can apply for Project SHARE assistance at The Salvation Army office in their county.

Supporting our communities

The Gulf Power Foundation gave $500,000 to United Way organizations across Northwest Florida to assist those most vulnerable during this time, which has helped support food, housing and other essential needs throughout the region. In addition, the Foundation recently made a $10,000 donation to Feeding the Gulf Coast and launched an employee donation campaign to provide food for our neighbors in need, while Entergy emergency relief fund offers a similar example of industry support. In total, Gulf Power and its fellow NextEra Energy companies and employees have so far committed more than $4 million in COVID-19 emergency assistance funds that will be distributed directly to those in need and to partner organizations working on the frontlines of the crisis to provide critical support to the most vulnerable members of the community.

Lower fuel costs are enabling Gulf Power to issue a one-time decrease of approximately 40% for the typical residential customer bill in May, even as FPL faces a hurricane surcharge controversy in the state
- a significant savings amid the ongoing COVID-19 pandemic

Gulf Power will deliver savings to customers through a one-time bill decrease, rather than the standard practice of spreading out savings over the remainder of the year, even as FPL proposes multi-year rate hikes elsewhere

Sudbury Hydro crews aim to reconnect service after storm

Sudbury Microburst Power Outage strains hydro crews after straight-line winds; New Sudbury faces downed power lines, tree damage, and hazardous access as restoration efforts, mutual aid, and safety protocols aim to reconnect customers by weekend.

 

Key Points

A microburst downed lines in New Sudbury, cutting power as crews tackle hazardous access and complex repairs.

✅ Straight-line winds downed poles, trees, and service lines

✅ Crews face backyard access hazards, complex reconnections

✅ Mutual aid linemen, arborists, and crane work speed restoration

 

About 300 Sudbury Hydro customers are still without power Thursday after Monday's powerful microburst storm, part of a series of damaging storms in Ontario seen across the province.

The utility's spokesperson, Wendy Watson, says the power in the affected New Sudbury neighbourhoods should be back on by the weekend, even as Toronto power outages persisted in a recent storm.

The storm, which Environment Canada said was classified as a microburst or straight line wind damage, similar to a severe windstorm in Quebec, downed a number of power lines in the city.

Now crews are struggling with access to the lines, a challenge that BC Hydro's atypical storm response also highlighted, as they work to reconnect service in the area.

"In some cases, you can't get to someone's back yard, or you have to go through the neighbour's yard," Watson said.

"We have one case where [we had] equipment working over a swimming pool. It's dicey, it's really dirty and it's dangerous."

Monday's storm caused massive property damage across the city, particularly in New Sudbury. (Benjamin Aubé/CBC)

Veteran arborist Jim Allsop told CBC News he hasn't seen damage like this in his 30-plus years in the business.

"I don't know how many we've done up to date, but I have another 35 trees on houses," Allsop said. "We'll be probably another week."

"We've rented a crane to help speed up the process, and increase safety, and we're getting five or six done in our 12-hour days."

Scott Aultman, a lineman with North Bay Hydro, said he has seen a few storms in his career, and isn't usually surprised by extensive damage a storm can cause.

"When you see a trailer on its side, you know, you don't see that every day," Aultman said.

But during the clean up, Aultman said the spirit of camaraderie runs high with crews from different areas, as seen when Canadian crews helped Florida during Hurricane Irma.

"We were pumped. It's part of the trade, everybody gets together," Aultman said. "We had a big storm in 2006 and the Sudbury guys were up helping us, so it's great, it's nice to be able to return the favour and help them out."

Green energy could drive Covid-19 recovery with $100tn boost

Renewable Energy Economic Recovery drives GDP gains, job growth, and climate targets by accelerating clean energy investment, green hydrogen, and grid modernization, delivering high ROI and a resilient, low-carbon transition through stimulus and policy alignment.

 

Key Points

A strategy to boost GDP and jobs by accelerating clean power and green hydrogen while meeting climate goals.

✅ Adds $98tn to global GDP by 2050; $3-$8 return per $1 invested

✅ Quadruples clean energy jobs to 42m; improves health and welfare

✅ Cuts CO2 70% by 2050; enables net-zero via green hydrogen

 

Renewable energy could power an economic recovery from Covid-19 through a green recovery that spurs global GDP gains of almost $100tn (£80tn) between now and 2050, according to a report.

The International Renewable Energy Agency’s new IRENA report found that accelerating investment in renewable energy could generate huge economic benefits while helping to tackle the global climate emergency.

The agency’s director general, Francesco La Camera, said the global crisis ignited by the coronavirus outbreak exposed “the deep vulnerabilities of the current system” and urged governments to invest in renewable energy to kickstart economic growth and help meet climate targets.

The agency’s landmark report found that accelerating investment in renewable energy would help tackle the climate crisis and would in effect pay for itself.

Investing in renewable energy would deliver global GDP gains of $98tn above a business-as-usual scenario by 2050, as clean energy investment significantly outpaces fossil fuels, by returning between $3 and $8 on every dollar invested.

It would also quadruple the number of jobs in the sector to 42m over the next 30 years, and measurably improve global health and welfare scores, according to the report.

“Governments are facing a difficult task of bringing the health emergency under control while introducing major stimulus and recovery measures, as a US power coalition demands action,” La Camera said. “By accelerating renewables and making the energy transition an integral part of the wider recovery, governments can achieve multiple economic and social objectives in the pursuit of a resilient future that leaves nobody behind.”

The report also found that renewable energy could curb the rise in global temperatures by helping to reduce the energy industry’s carbon dioxide emissions by 70% by 2050 by replacing fossil fuels, with measures like a fossil fuel lockdown hastening the shift.

Renewables could play a greater role in cutting carbon emissions from heavy industry and transport to reach virtually zero emissions by 2050, particularly by investing in green hydrogen.

The clean-burning fuel, which can replace the fossil fuel gas in steel and cement making, could be made by using vast amounts of clean electricity to split water into hydrogen and oxygen elements.

Andrew Steer, chief executive of the World Resources Institute, said: “As the world looks to recover from the current health and economic crises, we face a choice: we can pursue a modern, clean, healthy energy system, or we can go back to the old, polluting ways of doing business. We must choose the former.”

The call for a green economic recovery from the coronavirus crisis comes after a warning from Dr Fatih Birol, head of the International Energy Agency, that government policies must be put in place to avoid an investment hiatus in the energy transition, even as the solar and wind industry faces Covid-19 disruptions.

“We should not allow today’s crisis to compromise the clean energy transition, even as wind power growth persists despite Covid-19,” he said. “We have an important window of opportunity.”

Ignacio Galán, the chairman and CEO of the Spanish renewables giant Iberdrola, which owns Scottish Power, said the company would continue to invest billions in renewable energy as well as electricity networks and batteries to help integrate clean energy in the electricity.

“A green recovery is essential as we emerge from the Covid-19 crisis. The world will benefit economically, environmentally and socially by focusing on clean energy,” he said. “Aligning economic stimulus and policy packages with climate goals is crucial for a long-term viable and healthy economy.”

840 million people have no electricity – World Bank must fund more energy projects

World Bank Energy Policy debates financing for coal, oil, gas, and renewables to fight energy poverty, expand grid reliability, ensure baseload power, and balance climate goals with development finance for affordable, reliable electricity access.

 

Key Points

It outlines the bank's stance on financing fossil fuels and renewables to expand affordable, reliable electricity.

✅ Focus on energy access, baseload reliability, and poverty alleviation

✅ Debate over coal, gas, and renewables in development finance

✅ Geopolitics: China and Russia fill funding gaps, raising risks

 

Why isn’t the World Bank using all available energy resources in its global efforts to fight poverty? That’s the question I’ve asked World Bank President David Malpass. Nearly two years ago, the multilateral development bank decided to stop supporting critical coal, oil and gas projects that help people in developing countries escape poverty.

Along with 11 other senators, and as a member who votes on whether to give U.S. taxpayer dollars to the World Bank, I am pressing the bank to lift these restrictions. Developing countries desperately need access to a steady supply of affordable, reliable clean electricity to support economic growth.

The World Bank has pulled funding for critical electricity projects in poor countries, including high-efficiency power stations that are fueled by coal, even as efforts to revitalize coal communities with clean energy have grown.

Despite Kosovo having the world’s fifth-largest reserves of coal, the bank announced it would only support new energy projects from renewable sources going forward. Kosovo’s Minister of Economic Development Valdrin Lluka responded: “We don’t have the luxury to do such experiments in a poor country such as Kosovo. … It is in our national security interest to secure base energy inside our country.”

The World Bank’s misguided move comes as 840 million people worldwide are living without electricity, including 70 percent of sub-Saharan Africa, and as the fall in global energy investment may lead to shortages.

Even more troubling, nearly 3 billion people in developing countries rely on fuels like wood and other biomass for cooking and home heating, resulting in serious health problems and premature deaths, and the pandemic saw widespread electricity shut-offs that deepened energy insecurity. In 2016, household smoke killed an estimated 2.6 million people.

The World Bank’s mission is to lift people out of poverty. The bank is now compromising that mission in favor of a political agenda targeting certain energy sources.

With the World Bank blocking financing to affordable and reliable energy projects, Russia and China are stepping up their investments in order to gain geopolitical leverage.

President Vladimir Putin is pursuing Russian oil and gas projects in Mozambique, Gabon, and Angola. China’s Belt and Road Initiative is supporting traditional energy resources, with 36 percent of its power projects from 2014 to 2017 involving coal. South Africa had to turn to the China Development Bank to fund its $1.5 billion coal-fired power plant.

There are real risks for countries partnering with China and Russia on these projects. Developing countries are facing what some are calling China’s “debt trap” diplomacy. These nations have also raised concerns over safety compliance, unfair business practices, and labor standards.

As the bank’s largest contributor, the United States has a duty to make sure U.S. taxpayer dollars are used wisely and effectively. Every U.S. dollar at the World Bank should make a difference for people in the developing world.

My colleagues and I have asked the bank to pursue an all-of-the-above energy strategy as it strives to achieve its mission to end extreme poverty and promote shared prosperity. We will take the bank’s response into account during the congressional appropriations process.

The United States is a top global energy producer. And yet Democrats running for president are pursuing anti-energy policies that would hurt not only the United States but the entire world, with implications for U.S. national security as well.

Utilizing our abundant energy resources has fueled an American energy renaissance and a booming U.S. economy, even as disruptions in coal and nuclear have strained the grid, with millions of new jobs and higher wages.

People who are struggling to survive and thrive in developing countries deserve the same opportunity to access affordable and reliable sources of power.

As Microsoft founder and global philanthropist Bill Gates has noted of renewables: "Many people experiencing energy poverty live in areas without access to the kind of grids that are needed to make those technologies cheap and reliable enough to replace fossil fuels."

Ultimately, there is a role for all sources of energy to help countries alleviate poverty and improve the education, health and wellbeing of their people.

The solution to ending energy poverty does not lie in limiting options, but in using all available options. The World Bank must recommit to ending extreme poverty by helping countries use all of the world’s abundant energy resources. Let’s end energy poverty now.

Most Energy Will Come From Fossil Fuels, Even In 2040

2040 Energy Outlook projects a shifting energy mix as renewables scale, EV adoption accelerates, and IEA forecasts plateauing oil demand alongside rising natural gas, highlighting policy, efficiency, and decarbonization trends that shape global consumption.

 

Key Points

A data-driven view of future energy mix, covering renewables, fossil fuels, EVs, oil demand, and policy impacts.

✅ Renewables reach 16-30% by 2040, higher with strong policy support.

✅ Fossil fuels remain dominant, with oil flat and natural gas rising.

✅ EV share surges, cutting oil use; efficiency curbs demand growth.

 

Which is more plausible: flying taxis, wind turbine arrays stretching miles into the ocean, and a solar roof on every house--or a scorched-earth, flooded post-Apocalyptic world? 

We have no way of peeking into the future, but we can certainly imagine it. There is plenty of information about where the world is headed and regardless of how reliable this information is—or isn’t—we never stop wondering. Will the energy world of 20 years from now be better or worse than the world we live in now? 

The answer may very well lie in the observable trends.


A Growing Population

The global population is growing, and it will continue to grow in the next two decades. This will drive a steady growth in energy demand, at about 1 percent per year, according to the International Energy Agency.

This modest rate of growth is good news for all who are concerned about the future of the planet. Parts of the world are trying to reduce their energy consumption, and this should have a positive effect on the carbon footprint of humanity. The energy thirst of most parts of the world will continue growing, however, hence the overall growth.

The world’s population is currently growing at a rate of a little over 1 percent annually. This rate of growth has been slowing since its peak in the 1960s and forecasts suggest that it will continue to slow. Growth in energy demand, on the other hand, may at some point stop moving in tune with population growth trends as affluence in some parts of the world grows. The richer people get, the more energy they need. So, to the big question: where will this energy come from?


The Rise of Renewables

For all the headline space they have been claiming, it may come as a disappointing surprise to many that renewable energy, excluding hydropower, to date accounts for just 14 percent of the global primary energy mix. 

Certainly, adoption of solar and wind energy has been growing in leaps and bounds, with their global share doubling in five years in many markets, but unless governments around the world commit a lot more money and effort to renewable energy, by 2040, solar and wind’s share in the energy mix will still only rise to about 16 to 17 percent. That’s according to the only comprehensive report on the future of energy that collates data from all the leading energy authorities in the world, by non-profit Resources for the Future.

The growth in renewables adoption, however, would be a lot more impressive if governments do make serious commitments. Under that scenario, the share of renewables will double to over 30 percent by 2040, echoing milestones like over 30% of global electricity reached recently: that’s the median rate of all authoritative forecasts. Amongst them, the adoption rates of renewables vary between 15 percent and 61 percent by 2040.

Even the most bullish of the forecasts on renewables is still far below the 100-percent renewable future many would like to fantasize about, although BNEF’s 50% by 2050 outlook points to what could be possible in the power sector. 

But in 2040, most of the world’s energy will still come from fossil fuels.


EV Energy

Here, forecasters are more optimistic. Again, there is a wide variation between forecasts, but in each and every one of them the share of electric vehicles on the world’s roads in 2040 is a lot higher than the meagre 1 percent of the global car fleet EVs constitute today.
Related: Gas Prices Languish As Storage Falls To Near-Record Lows

Government policy will be the key, as U.S. progress toward 30% wind and solar shows how policy steers the power mix that EVs ultimately depend on. Bans of internal combustion engines will go a long way toward boosting EV adoption, which is why some forecasters expect electric cars to come to account for more than 50 percent of cars on the road in 2040. Others, however, are more guarded in their forecasts, seeing their share of the global fleet at between 16 percent and a little over 40 percent.

Many pin their hopes for a less emission-intensive future on electric cars. Indeed, as the number of EVs rises, they displace ICE vehicles and, respectively, the emission-causing oil that fuels for ICE cars are made from.  It should be a no brainer that the more EVs we drive, the less emissions we produce. Unfortunately, this is not necessarily the case: China is the world’s biggest EV market, and its solar PV expansion has been rapid, it has the most EVs—including passenger cars and buses—but it is also one of the biggest emitters.

Still, by 2040, if the more optimistic forecasts come true, the world will be consuming less oil than it is consuming now: anywhere from 1.2 million bpd to 20 million bpd less, the latter case envisaging an all-electric global fleet in 2040. 


This Ain’t Your Daddy’s Oil

No, it ain’t. It’s your grandchildren’s oil, for good or for bad. The vision of an oil-free world where renewable power is both abundant and cheap enough to replace all the ways in which crude oil and natural gas are used will in 2040 still be just that--a vision, with practical U.S. grid constraints underscoring the challenges. Even the most optimistic energy scenarios for two decades from now see them as the dominant source of energy, with forecasts ranging between 60 percent and 79 percent. While these extremes are both below the over-80 percent share fossil fuels have in the world’s energy mix, they are well above 50 percent, and in the U.S. renewables are projected to reach about one-fourth of electricity soon, even as fossil fuels remain foundational.

Still, there is good news. Fuel efficiency alone will reduce oil demand significantly by 2040. In fact, according to the IEA, demand will plateau at a little over 100 million bpd by the mid-2030s. Combined with the influx of EVs many expect, the world of 20 years from now may indeed be consuming a lot less oil than the world of today. It will, however, likely consume a lot more natural gas. There is simply no way around fossil fuels, not yet. Unless a miracle of politics happens (complete with a ripple effect that will cost millions of people their jobs) in 2040 we will be as dependent on oil and gas as we are but we will hopefully breathe cleaner air.

Iceland Cryptocurrency mining uses so much energy, electricity may run out

Iceland Bitcoin Mining Energy Shortage highlights surging cryptocurrency and blockchain data center electricity demand, as hydroelectric and geothermal power strain to cool servers, stabilize grid, and meet rapid mining farm growth amid Arctic-friendly conditions.

 

Key Points

Crypto mining data centers in Iceland are outpacing renewable power, straining the grid and exceeding residential electricity demand.

✅ Hydroelectric and geothermal capacity nearing allocation limits

✅ Cooling-friendly climate draws energy-hungry mining farms

✅ Grid planning and regulation lag rapid data center growth

 

The value of bitcoin may have stumbled in recent months, but in Iceland it has known only one direction so far: upward. The stunning success of cryptocurrencies around the globe has had a more unexpected repercussion on the island of 340,000 people: It could soon result in an energy shortage in the middle of the Atlantic Ocean.

As Iceland has become one of the world's prime locations for energy-hungry cryptocurrency servers — something analysts describe as a 21st-century gold-rush equivalent — the industry’s electricity demands have skyrocketed, too. For the first time, they now exceed Icelanders’ own private energy consumption, and energy producers fear that they won’t be able to keep up with rising demand if Iceland continues to attract new companies bidding on the success of cryptocurrencies, a concern echoed by policy moves like Russia's proposed mining ban amid electricity deficits.

Companies have flooded Iceland with requests to open new data centers to “mine” cryptocurrencies in recent months, even as concerns mount that the country may have to slow down investments amid an increasingly stretched electricity generation capacity, a dynamic seen in BC Hydro's suspension of new crypto connections in Canada.

“There was a lot of talk about data centers in Iceland about five years ago, but it was a slow start,” Johann Snorri Sigurbergsson, a spokesman for Icelandic energy producer HS Orka, told The Washington Post. “But six months ago, interest suddenly began to spike. And over the last three months, we have received about one call per day from foreign companies interested in setting up projects here.”

“If all these projects are realized, we won’t have enough energy for it,” Sigurbergsson said.

Every cryptocurrency in the world relies on a “blockchain” platform, which is needed to trade with digital currencies. Tracking and verifying a transaction on such a platform is like solving a puzzle because networks are often decentralized, and there is no single authority in charge of monitoring payments. As a result, a transaction involves an immense number of mathematical calculations, which in turn occupy vast computer server capacity. And that requires a lot of electricity, as analyses of bitcoin's energy use indicate worldwide.

The bitcoin rush may have come as a surprise to locals in sleepy Icelandic towns that are suddenly bustling with cryptocurrency technicians, but there’s a simple explanation. “The economics of bitcoin mining mean that most miners need access to reliable and very cheap power on the order of 2 or 3 cents per kilowatt hour. As a result, a lot are located near sources of hydro power, where it’s cheap,” Sam Hartnett, an associate at the nonprofit energy research and consulting group Rocky Mountain Institute, told the Washington Post.

Top financial regulators briefed a Senate panel on Feb. 6 about their work with cryptocurrencies like Bitcoin, and the risks to potential investors. (Reuters)

Located in the middle of the Atlantic Ocean and famous for its hot springs and mighty rivers, Iceland produces about 80 percent of its energy in hydroelectric power stations, compared with about 6 percent in the United States, and innovations such as underwater kites illustrate novel ways to harness marine energy. That and the cold climate make it a perfect location for new data-mining centers filled with servers in danger of overheating.

Those conditions have attracted scores of foreign companies to the remote location, including Germany's Genesis Mining, which moved to Iceland about three years ago. More have followed suit since then or are in the process of moving. 

While some analysts are already sensing a possible new revenue source for the country that is so far mostly known abroad as a tourist haven and low-budget airline hub, others are more concerned by a phenomenon that has so far mostly alarmed analysts because of its possible financial unsustainability, alongside issues such as clean energy's dirty secret that complicate the picture. Some predictions have concluded that cryptocurrency computer operations may account for “all of the world’s energy by 2020” or may already account for the equivalent of Denmark's energy needs. Those predictions are probably too alarmist, though. 

Most analysts agree that the real energy-consumption figure is likely smaller, and several experts recently told the Washington Post that bitcoin — currently the world's biggest cryptocurrency — used no more than 0.14 percent of the world’s generated electricity, as of last December. Even though global consumption may not be as significant as some have claimed, it still presents a worrisome drain for a tiny country such as Iceland, where consumption suddenly began to spike with almost no warning — and continues to grow fast.

Some networks are considering or have already pushed through changes to their protocols, designed to reduce energy use. But implementing such changes for the leading currency, bitcoin, won't be as easy because it is inherently decentralized. The companies that provide the vast amounts of computing power needed for these transactions earn a small share, comparable to a processing fee or a reward.

They are the source of the Icelandic bitcoin miners’ income — a revenue source that many Icelanders are still not quite sure what to make of, especially if the lights start flickering.
