Iceland is moving closer to plugging European homes into the volcanic island nation’s geothermal and hydropower reserves via what would be the world’s longest power cable, according to the country’s largest energy producer.

Electric utilities seeking the renewal of their franchises, and politicians seeking municipalization, both ignore the transformative possibilities of the microgrid. Microgrids represent a promising new business opportunity for both existing utilities and new entrants in the electricity business. Microgrid deployment will also provide the same public benefits as municipal control, likely more.

Nuclear power, which accounts for 19 percent of the nation's electricity generation, is facing some serious challenges. Not only did its hoped-for renaissance fizzle out, four reactors shut down last year, another is closing this fall, and the nuclear giant Exelon says it will announce plant closings by the end of this year if market conditions don't improve.

Meeting the world’s energy supply needs by 2035 will require $40 trillion of investment, as demand grows and production and processing facilities have to be replaced, the International Energy Agency said.

On what effect the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan will have on transmission development in the country, including potentially a need for more transmission to transport added renewable energy, Frank Poirot, senior media specialist of transmission with Northeast Utilities (NYSE:NU) told TransmissionHub that increasing the grid's capacity to transmit power is one way to meet the growing need and enable renewable generation.

On the heels of the EPA’s new carbon rules proposed by President Obama on June 2, I wanted to take a closer look at a potential disruptive technological breakthrough: taking CO2 waste streams and turning them into saleable, value-added feedstocks. Certainly, the deployment of renewables, energy efficiency, smart grid, and energy storage technologies offer some of the most cost-effective options for dramatically reducing emissions. But if you believe that fossil fuel power plants (along with other large-source emitters like steel and cement producers) will remain a part of our industrial ecosystem for some time to come, then capturing and utilizing C02 from these emitters is an important and critical piece of the carbon-management equation.

Power infrastructure in the East African countries of Uganda, Kenya, Tanzania and Rwanda is inherently connected to their economic growth. As urbanisation and industrialisation fuel the need for electricity in cities, the demand for electricity in East Africa is expected to grow at approximately 5.3 percent per year until 2020. To meet these requirements, generation capacity would have to increase by 37.7 percent in Uganda, 96.4 percent in Kenya, 75.3 percent in Tanzania and 115 percent in Rwanda. The government, in conjunction with development partners, must build a more favourable business environment to facilitate growth.

The argument industrial polluters and their friends in Congress are making against the new Environmental Protection Agency plan to curb power plant carbon emissions should sound familiar. After all, it's the same scare tactic they trot out every time the government proposes stricter emission controls: exaggerate the cost, overstate job losses, and completely ignore the benefits.

"Big data" is playing an increasingly big role in the renewable energy industry and the transformation of the nation's electrical grid, and no single entity provides a better tool for such data than the Energy Department's Energy Systems Integration Facility (ESIF) located on the campus of the National Renewable Energy Laboratory (NREL). Imagined by NREL leaders who foresaw the possibilities for high performance computing (HPC), the ESIF's HPC data center is fulfilling the goal of handling large and complex datasets that exceed traditional database processes.

Energy use in the U.S. can be split into two large (very, very large) pies. One is electricity for use in homes, buildings, and industry, and the other is transportation, which is powered primarily by liquid fuels (gasoline and diesel) from oil. There are some exceptions, and small overlapping fuel uses — direct industrial use of liquid fuel (a fairly significant quantity), some liquids burned to make electricity (this used to be a significant amount, but is now only a very small amount), and now a very small amount of electricity used to power electric vehicles (EVs).

July was a hard month for the stock market and clean energy stocks in particular. My broad market benchmark of small cap stocks, IWM, fell 7 percent and is down 2.7 percent for the year, while my clean energy benchmark PBW fell 9% and has slid into the red for the first time. It is down 0.1 percent for the year to date.

It's the environmentalist's third rail question: "Should we promote nuclear power as an expedient way to reduce CO2 emissions?" On the one hand, nuclear power generates electricity with almost negligible CO2 emissions — potentially a good way for our society to reverse the current global warming trends. On the other hand, nuclear power is...well...nuclear. Problems related to waste disposal, proliferation and high costs have not been solved, and we still have the occasional disaster.

“The times they are a' changin'.” So goes Bob Dylan's classic song from the '60s, and that's certainly the case when it comes to how we generate, distribute, use and store electricity. Having made great strides in enhancing performance and reliability and reducing costs, growing government support and incentives for intelligent energy storage solutions adds significant impetus to the growing wave of change sweeping across the U.S. power sector.

Abengoa SA, a Spanish energy and environment company, plans to issue its first green bond to raise 500 million euros ($642 million) to finance projects.

The threat of climate change is driving China and the U.S. — frequent rivals and the world’s two largest greenhouse-gas emitters — to collaborate on dozens of potential clean-energy breakthroughs.

More than 100 world leaders converged upon New York City today to discuss international efforts to reduce carbon emissions and combat climate change. The list of speakers at the UN Climate Summit included U.S. President Barack Obama, UK Prime Minister David Cameron, Brazilian President Dilma Rousseff, French President François Hollande, and Chinese Vice Premier Zhang Gaoli.

California and Quebec, which together created the largest carbon market in North America this year, may come away empty-handed as they woo northeastern U.S. states to join their system.

Worries including the conflict with ISIL, Ebola, and economic slow-down in Europe, sent the stock market down in the month to October 3rd, with small cap stocks and clean energy stocks falling even farther than the large cap S&P 500.

The renewable energy market is fast-paced and growing with each passing day. It’s hard to keep up with every industry announcement and insight, so we decided to highlight interesting developments that took place during the past few weeks, and some valuable insights that are worth revisiting.

German electricity consumers will for the first time see a drop in the fee added to their bills to fund renewables, a boost for Chancellor Angela Merkel, who has pledged to curb the cost for voters.

Last month, NRDC engaged a nationally recognized opinion research firm to conduct polling in New York State to evaluate public attitudes about fracking and clean energy. Importantly, this is the first statewide poll in at least two years — and perhaps ever — to directly ask residents their views of the now six-year-old de facto moratorium on fracking.

Imagine a place where there is no electricity market. No rules, no policies, no market. A clean slate. This is what the Solar Energy Power Association (SEPA) calls the 51st State, a new initiative to get people to think outside the box when it comes to utility design and infrastructure.

European Union leaders backed the most-ambitious carbon emissions goals of any major economy, in a bid to crank up pressure on the U.S. and China ahead of climate talks in December.

Every time the U.S. holds midyear elections, the country almost always goes against the incumbent President’s party, which is always sobering to whomever holds The White House. And this week’s elections were no exception.

President Barack Obama pledged deeper U.S. cuts in greenhouse-gas emissions and China will for the first time set a target for capping carbon emissions under an agreement between the world’s two biggest economies.

In early 2013, a group of women, dubbed the Women in Power committee, assembled in Orlando, Florida to figure out how to honor women who have dedicated their careers to the power industry. The industry is male-dominated with men making up more than 75 percent of the workforce, according to estimates.

This year’s Project of the Year Award finalists truly represent the evolving energy landscape and exciting global efforts to transition to a cleaner, renewable future. The five projects vying for the Renewable Energy Project of the Year crown include a wide range of innovative technologies from coal-to-biomass conversion to concentrating solar power.

While OPEC is helping drive down global prices for crude, it’s having less success squeezing the $250 billion clean power industry.

The Western States Petroleum Association (WSPA) — whose members include Chevron, ExxonMobil, Shell, ConocoPhillips, BP, and others — was caught red-handed late last month when a leaked internal presentation revealed a coordinated campaign to stomp out climate and clean energy progress in California, Oregon and Washington by propping up over 15 front groups that purport to represent the views of concerned citizens and the broader business community.

Let's review some notable news headlines from the month of November.

Shinzo Abe’s re-election as prime minister risks undercutting Japan’s commitment to clean energy at a time when incentives are under review and the nation’s utilities say they can’t accommodate capacity already planned.

Despite years of successful experience, dozens of studies, and increasing utility support for clean energy, urban myth holds that electricity from renewable energy is unreliable. Yet over 75,000 megawatts (MW) of wind and solar power have been integrated, reliably, into the nation’s electric grid to date. That’s enough electricity to supply 17.9 million homes.

At the close of each year, we like to take a look back to see which stories made an impact on our readers. This year's most read articles show the many twists and turns that the industry took this year and reveal interesting trends for us as editors and for other industry insiders.

In June, the U.S. Environmental Protection Agency (EPA) proposed a rule to restrict the amount of carbon dioxide released from power plants. The rule calls for reducing carbon 30 percent by 2030 over 2005 levels. Many have praised the aggressive proposal, while others are less favorable.

Although the U.S. made it through a quiet 2014 Atlantic hurricane season this year, it doesn’t mean we’re out of the waters. Natural disasters are an ongoing threat to our infrastructure, and utilities need to be conscious of the present state and future of our power grid. Fortunately, in recent years many utilities across the country have recognized the importance of being prepared for major storms, and have been actively researching and implementing solutions to prepare for the next big one.

2015 marks my seventh annual list of ten clean energy stocks. An equal weighted portfolio of the ten stocks in each year's list has outperformed my industry benchmark every year except 2013. 2014 was no exception, but it was a bittersweet victory in that the model portfolio was slightly down while the benchmark lost considerably more in a very challenging year for clean energy stocks.

Hybrid car sales have taken off in recent years, with a fuel-sipping combination of electric- and gas-powered technologies that simultaneously deliver energy efficiency, low emissions, and strong performance. The Energy Department's National Renewable Energy Laboratory (NREL) — which played a pivotal role in putting hybrids on the road — has applied a similar strategy to its talent base and partnerships, bringing together the best minds from the worlds of research and industry.

Clean energy investments in India increased to $7.9 billion last year and are expected to surpass $10 billion in 2015.

Oil prices have fallen by more than half since July. Just five years ago, such a plunge in fossil fuels would have put the renewable-energy industry on bankruptcy watch. Today: Meh.

California’s bet on green energy is paying off, with clean technology companies creating more jobs and investing more money than competitors in any other state.

Ending a year-long race that had been nip-and tuck every month, renewable energy sources cumulatively provided more new electric generating capacity in 2014 than did natural gas.

The recent dramatic plunge in oil and natural gas prices, to their lowest level since the global recession in 2009, has some observers worried about the effect on clean tech. Conventional wisdom has it that renewables have a tougher time competing when fossil fuels are cheap, making grid parity (in the case of natural gas-fired electricity) more elusive for solar and wind power.

Cleantech investing has taken quite a hit in recent years. Last year, CBS News highlighted the “cleantech crash” on U.S. primetime television, and Bloomberg New Energy Finance, a Bloomberg-owned energy data firm, has tracked the multi-year decline in cleantech investing. However, there are additional trends that tell another side of the cleantech story and suggest innovation and hope for a low-cost, low-carbon future are far from gone.

In a previous article, I had a conversation with former-CIA chief Jim Woolsey to discuss one of America’s greatest national security vulnerabilities, its power grid. The issues that Woolsey has been concerned with for over a decade has been the ease in which a terrorist group or other actor (think North Korea for example) could attack the grid and plunge the country into darkness for months, if not years. And if that seems far-fetched, just recall how a tree limb fell in Ohio in 2003 and blacked out the entire Northeast and part of Canada for several days.

In a crammed Washington conference room last week, speaker after speaker seemed to apologize for their ‘broken record’ talking points as Bloomberg New Energy Finance and the Business Council for Sustainable Energy unveiled their annual Factbook. But, of course, they were only being honest — like 2013 before it, 2014 had been an unprecedented year for clean energy.

Last year the U.S. Environmental Protection Agency (EPA) proposed its aggressive Clean Power Plan (CPP), which calls to reduce carbon emissions 30 percent by 2030 over 2005 levels. States are required to submit reduction plans that can include increasing renewables, efficiency, and cap and trade programs by June 2016.

When I worked at the New York Attorney General's Office, we sued coal-fired power plants because their air pollution was making people sick. But in some towns, I saw that the reliance on coal really had people in a bind. The coal plant was making them sick, but it was also a major tax generator for the town. If the plant closed, the town might have to lay off teachers and cops, in addition to losing the plant jobs.

The European Commission has unveiled “A Framework Strategy for a Resilient Energy Union with a Forward-Looking Climate Change Policy,” which is a key plank in the development of its plans for Europe’s energy sector through 2030.

The first round of the Contracts for Difference (CfD) programme — the UK scheme that is designed to support low-carbon generation and a capacity margin in the energy sector — has concluded. Contracts were offered to 27 renewable electricity projects with a total value of some £315 million (US$500 million), which include two offshore wind farms with a total planned capacity of more than 1.1 GW, 15 onshore wind projects and five solar projects. In total, more 2 GW of new low-carbon capacity (including renewables, nuclear and carbon capture and storage) could be built under the CfD scheme.

Policies favoring clean energy and increased competition would normally dim prospects for existing producers. Not in Chile, where foreign investors are driving a renewable boom at a time of surging returns by local utilities.
