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.

U.S. electricity markets face years of higher prices as clean-air regulations shut more coal-fired power plants than earlier forecast, cutting supply and forcing producers to rely more on natural gas.

Humans are causing irreversible damage to the planet from burning fossil fuels, the biggest ever study of the available science concluded in a report designed to spur the fight against climate change.

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.

President Barack Obama will pledge $3 billion to a United Nations climate-change fund that’s intended to help poor nations boost renewable energy and counter the ill effects of global warming.

Halifax Regional Municipality of Nova Scotia, Canada, is the first Canadian city to use an in-pipe hydroelectric generation system within a pressurized water distribution pipeline, according to Halifax Water. On Nov. 13, a 32-kW generating system within a drinking water distribution control chamber for Halifax Water began providing power.

According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's (FERC) Office of Energy Projects, wind power provided over two-thirds (68.41 percent) of new U.S. electrical generating capacity in October 2014. Specifically, five wind farms in Colorado, Kansas, Michigan, Nebraska, and Texas came on line last month, accounting for 574 MW of new capacity.

The clean energy revolution is now, and the U.S. Energy Department is stepping up its commitment to help innovators commercialize their best ideas. At the recent Industry Growth Forum (IGF) in Denver, Colorado, Assistant Secretary for Energy Efficiency and Renewable Energy David Danielson announced the new Lab-Corps program to accelerate the transfer of clean energy technologies from the national laboratories to the marketplace, so that game-changing innovations don't languish for lack of money and equipment.

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.

The National Hydropower Association and Ocean Renewable Energy Coalition have announced the formation of the Marine Energy Council, which will offer a new home for marine energies at NHA.

The siren call of 2020 corporate environmental sustainability goals is quickly getting louder, as corporate leaders realize they must go further today to achieve their sustainability targets for tomorrow. Increased use of renewable energy is an ambitious goal for some of the world’s largest companies, as 59 percent of the Fortune 100 and nearly two-thirds of the Global 100 have set GHG emissions reduction commitments, renewable energy commitments or both, according to a recent Ceres’ report, Power Forward: Why the World’s Largest Companies Are Investing in Renewable Energy. One global consumer products company, for example, plans to derive 30 percent of its energy from clean sources by 2020.

Renewable energy stakeholders are well aware that clean energy is slowly but steadily transforming the energy landscape and that message couldn’t have been more clear at the recently concluded Power-Gen International, the largest show for the traditional power generation industry. Since all forms of power generation are represented at the show through the four co-located conferences, PennWell calls the second week in December "Power Generation Week."

The U.S. Department of Commerce just announced that it will add high tariffs for solar modules imported from China. The Canadian government is also investigating the adoption of similar measures, following recent complaints filed by Ontario-based solar manufacturers. With the solar industry in hypergrowth, it’s not a surprise that these governments are interested in boosting new jobs, protecting their economies, and fostering the solar sector. The problem is that tariffs are a short-sighted approach that actually attack the future of North American solar on its home soil, and likely destroy more jobs than they create.

Earlier this month, when EPA proposed a new health-protective air quality standard for the pollutants that form “ozone,” some critics predictably pounced on it as another example of a long string of “job-killing EPA regulations.” Yet last week, we learned that the U.S. economy created about 320,000 new jobs in November, and average wages are starting to rise as the labor market tightens.

As the holidays wind to a close and we ring in the new year, sit back and relax with your favorite libation and enjoy our most popular videos of the year. We guarantee you will learn something new.

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.

California Governor Jerry Brown proposed spending $59 billion to fix crumbling roads and raising the state’s renewable energy mandate to 50 percent.

President Obama has been under intense scrutiny for what he would do about climate change ever since he was elected in 2008. Part of that scrutiny takes place during his State of the Union Speech, when renewable energy proponents search for key words about solar and wind energy and count how often he mentions "climate change."

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.

A tool only has value if it’s used. For example, you could be the sort of person who’s set a goal of wanting to exercise more. If someone gives you a nifty little Fitbit to help you do that, and you never open the box, how useful, then, is this little device? The same is true about smart energy management solutions: good tools exist, but whether it’s calories or energy use that you want to cut, at some point those helpful devices need to be unpacked.

The Obama administration is proposing a $4 billion fund to reward states that exceed cuts in greenhouse-gas emissions, and wants Congress to back steeper royalty rates for oil, gas and coal extraction from public land.

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.

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.

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.

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.

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.

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.

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…

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.

This week New York Governor Andrew M. Cuomo announced the signing of an agreement between the New York Power Authority (NYPA) and State University of New York Polytechnic Institute (SUNY Polytechnic) that aims “to create a world-class facility devoted to energy technology innovation and the rapid deployment of smart-grid technology to modernize New York's electric grid.”

It’s been a big news day in the U.S. Senate, with Senate Democratic Leader Harry Reid announcing he won’t run for another term.

Mexico has become the first developing nation to formally promise to cut its global-warming pollution, a potential milestone in efforts to reach a worldwide agreement on tackling climate change.

The proposed U.S. commitment to tackling climate change in support of a new international climate agreement is a serious and achievable plan that demonstrates the United States is ready to take significant action. Coming today, eight months before the UNFCCC Conference of the Parties in Paris this December, known as COP 21, the U.S. submission adds momentum toglobal climate negotiations and should help spur other countries to act.

Researchers at Yale have unveiled a new interactive map that estimates public opinion on global warming right down to the county level.

In our second annual survey on American homeowners’ attitudes toward clean energy, one thing is resoundingly clear. In a nation divided on climate change, immigration policy, and so many other issues, Americans are overwhelmingly united in their support of renewable energy.

Yale University police cited 19 students after they staged a sit-in outside President Peter Salovey’s office to push for divestment from fossil-fuel companies.

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.

Brazil will increase the use of renewable energy, target zero net deforestation and push for low-carbon agriculture as part of its climate proposal, Environment Minister Izabella Teixeira said in an interview.

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.

Europe’s utilities are re-evaluating their business models due to the energy transition. Members of POWER-GEN Europe’s Advisory Board consider how a reliance on fossil fuels is no longer politically desirable, forcing utilities to transform their portfolios to adapt to radical change.

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.

Alternative energy became a serious market player after the turn of the millennium. Since that time, solar, wind, smart grid and other alternative energy stocks have experienced both strong up and down trends. The forces at work driving these markets are complex, counterintuitive, and sometimes mysterious. This article looks at what has been driving the price of alternative energy markets, and as a result, alternative energy company stocks.

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.
