We often post news that we feel will get people to view important topics from new angles, offering insights and opinions about technology, policy and more. Often that leads to engaging and informative discussions that add even more value to the article that we have posted.

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 May of 2014, Speaker of the House John Boehner responded to a climate change question with, “listen, I’m not qualified to debate the science over climate change. I am astute to understand that every proposal that has come out of this administration to deal with climate change involves hurting our economy and killing American jobs. That can’t be the prescription for dealing with changes to our climate.” Speaker Boehner is not the only one reluctant to enter into the debate on climate change. In a March interview Mitch McConnell responded to a climate change remark with, “For everybody who thinks it's warming, I can find somebody who thinks it isn't…”

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.

Not all alternative energy mutual funds are created equal. In a recent interview with the Wall Street Journal, a reporter asked me which alternative energy mutual funds were the most focused on renewables, noting that many mutual funds hold non-energy related companies such as Apple, PepsiCo and Google. The answer to this question is not as straight forward as one might think. This article sorts out which mutual funds are truly invested in the dynamic and growing green energy sector, and which ones are more peripheral.

In visualizing microgrids as smaller versions of the existing grid, we ignore a whole new dimension of the impending electricity revolution that I wish to call “microgrid as metaphor,” and distinguish it from “microgrid as fact.” Let me elaborate.

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

China is mulling a policy to provide a subsidy for lithium batteries deployed in electric vehicles. This new favorable policy is expected to propel the development of the country’s electric vehicle sector. China has existing subsidy policies for the sector, but higher prices for the parts used in electric vehicles, in particular lithium batteries, prevent many consumers from purchasing the vehicles.

The UN climate conference in Lima set the stage for Paris in 2015. Next year’s accord is to provide a working, albeit not a final, answer to the question: Is it possible to keep global warming at or below the 2 degree Celsius limit? This limit is considered the boundary beyond which the negative climatic, economic and social consequences of climate change are thought to become intolerably severe and potentially irreversible.

The Brazilian bank Itau Unibanco Holding SA raised 1.05 billion reais ($408 million) to finance renewable energy and water treatment projects.

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.

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.

Germany’s utilities, battered by the country’s shift to wind turbines and solar panels, would be glad to sell you a power plant on the cheap. They’ll even pack it up and ship it to another country.

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.

For many mining companies, the rallying cry for investigating solar or wind energy options has been that the price of oil and other conventional fuels is too high — and will almost certainly rise over time. Now, though, with oil prices having taken a dramatic nosedive, this argument no longer packs quite the same punch that it once did.

India said cheaper credit along with foreign investment will help the world’s third-largest polluter fund an ambitious renewable energy program that would build green power plants faster than China.

Apple Inc. may already be positioned to evolve into a global automaker in many ways that other Silicon Valley companies aren’t.

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 renewable energy industry has come a long way in relatively little time. The costs of renewable technologies continue to go down, while renewable capacities at many utilities continue to go up. Although, in many cases, renewable technology is mature and ready for utility-scale deployment, state and federal production and investment tax policies appear less evolved.

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.

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.

Iberdrola SA, Spain’s largest electricity company, agreed to buy UIL Holdings Corp. in a deal valued at about $3 billion in cash and shares to create a U.S. utility with about 3.1 million customers.

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.

In recent months, a veritable open patent war has erupted between Tesla Motors and Toyota. Both companies have been widely cited in the industry and financial press for their respective announcements opening up their electric vehicle (Tesla) and fuel cell (Toyota) patents. Tesla CEO Elon Musk opened the first salvo with a blog post last June in which he announced that Tesla would “not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.”

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.

The annual outlook issue of Renewable Energy World magazine is our attempt to predict what will happen within the renewable energy industry over the course of the year. To do this, we went straight to the top of major renewable energy companies, asking CEOs and presidents to tell us where they are devoting their company resources in order to capitalize on some of the market growth that they expect to see in 2015.

In a must-read report released this week on fast-changing energy markets, the National Bank of Abu Dhabi signals a once-in-a-lifetime opening for investors in Middle Eastern renewables and energy efficiency.

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.

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.

The Russian Prime Minister Dmitry Medvedev has amended Russia’s federal law on the electric power industry. Ordinance No47 lays out a number of measures aiming to stimulate renewable energy sales in the national retail market.

We love electric vehicles (EVs) in California and we want that love to spread. Why? It isn’t because of the cool factor — though, believe me, EVs like the Tesla are undoubtedly cool. Instead, it’s because these cars can offer significant benefits to the environment, electric grid, and economy.

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.

Following the conclusion of the United Nations climate negotiations in Lima, Peru, last December, a busy schedule of breakout sessions has begun for Latin American business and political leaders in early 2015.

Ormat is a successful developer of geothermal energy projects. Two former employees have brought a lawsuit alleging that Ormat made inaccurate 1603 Cash Grant submissions to obtain grants for projects that should not have qualified for such grants.

Beijing, where pollution averaged more than twice China’s national standard last year, will close the last of its four major coal-fired power plants next year.
