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.

For the past 13 years, Clean Edge has published the annual Clean Energy Trends report that has sized the global market for solar, wind, and biofuels and tracked everything from venture capital and stock market activity to total global investments. This year, instead of issuing one single report, we'll be producing infographics, tables, charts, and webinars throughout the year – so be on the lookout in the coming weeks and months.

The lush hills of Strangford Lough are truly a place of magic scenery. Portaferry, a small fishing village, is located one hour’s drive from Belfast in Northern Ireland, and is today perhaps most famous for being close to the location where blockbuster Games of Thrones is filmed. In this idyllic fishing village, struggling with a high unemployment rate and a diminishing population, something new and prosperous is growing. Looking out over the calm waters of Strangford Lough, one could hardly believe that under the ocean surface — that electricity can be produced.

Researchers at Chalmers University of Technology have discovered that the insulation plastic used in high-voltage cables can withstand a 26 per cent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.

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.

2015 got off to a rocky start for both the broad market in general, as well as clean energy.

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.

Actress Natalie Portman, environmentalist Robert F. Kennedy, Jr., and other high-profile Harvard University alumni are calling for demonstrations to urge divestment from fossil fuels.

Apple and Google have changed our lives forever, both because of their technological innovations and sheer size as global corporations. Now, they’re aiming to reshape the energy landscape.

After a rough start to the year, My Ten Clean Energy Stocks for 2015 posted a strong recovery in February.

Many businesses can now perform the traditional functions of an electric utility — provide affordable, reliable, resilient power to homes and businesses. The barriers to entry in the business have fallen. For instance, a home with rooftop solar panels, batteries, and gas-based generators may choose to be grid-independent. Even when homes decide to remain grid-tied, utilities face falling demand and revenue, and the possibility of future grid-defection. Further, competing electricity solutions can emerge quickly, and not one-home-at-a-time — microgrids can offer community, village, or campus-level solutions.

Business leaders have an important decision to make this year: to continue operating under the status quo or to join the list of successful companies creating a more sustainable future by contracting or investing in renewable energy and making a positive impact on their brand, customers, employees and bottom line.

Global emissions were unchanged last year, the first time that’s happened amid economic growth in four decades, according to the International Energy Agency.

Sweden and Norway agreed to boost their target for renewable energy production amid concerns the additional capacity will exacerbate a power glut and strain the region’s electricity grid.

Sen. Troy Fraser (R-Horseshoe Bay) has filed a bill that would eliminate Texas’ Renewable Portfolio Standard (RPS) – a policy that has catapulted Texas to world leadership in wind energy and strengthened Texas’ energy diversity. In addition to terminating the RPS at the end of the year, SB 931would make it more difficult to build renewable energy infrastructure. The argument behind the bill is that because Texas has achieved its RPS goals it’s time to move on. Sounds reasonable, right? Well…

President Barack Obama ordered the federal government to reduce greenhouse gas emissions by 40 percent from 2008 levels over the next 10 years by shifting to renewable energy sources such as solar power.

The U.K. company planning the world’s first tidal-lagoon power station said its next plant may generate electricity at almost half the price.

My Ten Clean Energy Stocks for 2015 model portfolio added a second month to its winning streak, with a 6.1 percent gain for the month and a 5.7 percent gain for the year, despite a continued drag by the strong dollar. If measured in terms of the companies' local currencies, the portfolio would have been up 7.5 percent for the month and 10.5 percent for the quarter or year to date. For comparison, the broad universe of US small cap stocks rose 1.5 percent for the month and 4.0 percent for quarter, as measured by IWM, the Russell 2000 index ETF.

A report released recently by the International Energy Agency's Ocean Energy Systems shows that the marine and hydrokinetic sector moved closer to commercial viability through 2014.

A "dark horse" is defined as a little-known entity that emerges to prominence in the face of competition — a contestant that seems unlikely to succeed. I borrow the term from a conversation last week, wherein India was referred to as the dark horse in the global race to go solar.

Reflecting the azure skies of the Caribbean, solar panels on private houses, hotels and businesses are an increasingly common sight across all the islands. Many Caribbean customers are seeking a degree of energy independence, which is not surprising given that many pay five or six times as much for their grid-provided electricity than their neighbours in mainland USA.

According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's (FERC) Office of Energy Projects, wind, solar, geothermal, and hydropower combined provided over 75 percent (75.43 percent) of the 1,229 megawatts (MW) of new U.S. electrical generating capacity placed into service during the first quarter of 2015. The balance (302 MW) was provided by natural gas.

Japan anticipates that by 2030 clean energy such as solar and hydro will generate slightly more of the nation’s electricity than nuclear power plants.

The surprise Conservative victory in the recent UK elections have some worrying about the future of renewable and climate progress, but officials are now calming those fears.

Last week, Canada has announced its contribution to the global effort to reduce greenhouse gases by announcing its post-2020 target. The target announced today is off-track to the 80 percent cut by 2050 they committed to in 2009 and significantly higher than the U.S. target. They also announced a series of new measures, but failed to address their largest source of growing emissions — tar sands.

Every industry has its challenges and misunderstandings. Sometimes the obstacles we face in simply trying to do our jobs can be very frustrating.

Carbon emissions in 2014 remained at the previous year’s levels of 32.3 billion metric tons — a milestone that points to the impact worldwide renewable energy investment is having in the face of a 1.5 percent annual increase in global energy consumption, according to a new report from REN21. The tenth annual Renewables 2015 Global Status Report cites “increased penetration of renewable energy” and improvements in energy efficiency as the chief reasons for the noted emissions stabilization.

The government abandoned talks on proposals to impose a climate-change fee that the industry said would have forced mines and plants to close, threatening jobs.

Oregon Gov. Kate Brown, Democrat, has proclaimed “July 13-17, 2015 to be Oregon Wave Week in Oregon and encourages all Oregonians to join in this observance.”

This month alone, we Americans celebrated our nation’s birthday, capped off perfectly by the USA women’s soccer team’s sensational 5-2 victory in the World Cup final. As we hit the halfway point of 2015, the clean-energy industry also has much to celebrate, much of it in the month of June alone and much of it financial.

Publicly, the United Nations climate-change talks look mired in disputes over everything from money to the length of the proposed agreement.

Executives from 13 major U.S. corporations are announcing at least $140 billion in new investments to decrease their carbon footprints as part of a White House initiative to recruit private commitments ahead of a United Nations climate-change summit later this year in Paris.

Companies including Apple Inc., Berkshire Hathaway Energy Co., and Goldman Sachs Group Inc. will join Secretary of State John Kerry and top administration officials at the White House for the announcement. In addition to pledges to cut emissions, provide financing to environmentally-focused companies, and reduce water consumption, the companies have said they will procure at least 1,600 MW of new, renewable energy. The White House said in a statement that it expects to announce a second round of similar pledges later this fall from additional companies.

The commitments are being announced as President Barack Obama is looking to build momentum toward a legacy-defining global climate accord in Paris. In addition to company-specific commitments, the corporate leaders on Monday will signal their support for a strong climate agreement out of the United Nations talks. They administration is using the pledges to set an example for companies to find ways to eliminate their carbon emissions.

Climate Talks

“As the world looks toward global climate negotiations in Paris this December, American leadership at all levels will be essential,” the White House said in a fact sheet detailing the announcement.

The administration’s actions are pushing the issue into the 2016 presidential debate. Hillary Clinton, the front-runner for the Democratic nomination, released an energy strategy saying she would both defend and go beyond Obama’s efforts. Republican candidates have criticized the administration’s initiatives as costly to the economy and unnecessary.

Among the pledges, aluminum manufacturer Alcoa Inc. has agreed to reduce emissions by 50 percent from its 2005 levels, while agricultural giant Cargill Inc. says 18 percent of its total energy use will come from renewable sources.

Coca-Cola Co. said it would drive down the carbon footprint of its beverage production by 25 percent over the next five years, while Google says it plans to triple its purchases of renewable energy over the next decade. Berkshire Hathaway says it plans to invest up to an additional $15 billion in the construction and operation of renewable energy generators, while Bank of America Corp says it will increase its environmental business initiative by $75 billion over the next decade, according to the White House

Other participating firms include Wal-Mart, United Parcel Service Inc., PepsiCo Inc., Microsoft Corp., General Motors Inc.

The corporate commitments won’t be the administration’s only major climate announcement in the next few weeks. The Environmental Protection Agency is set to present final regulations that aim to reduce carbon emissions from power plants by 30 percent from 2005 levels by 2030 later this week.

While visiting Kenya over the weekend, Obama repeatedly praised the country for its efforts to address climate change, saying its efforts tor educe emissions “has put it in the position of being a leader on the continent.” And next month, the president will travel to Alaska for an international summit on Arctic climate issues.
