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.

A new report by utility and finance experts contains positive news for the environment, our air and our (and our utilities’) pocketbooks — the economics of electric power resources have made zero-emissions energy efficiency and renewable energy technologies the most financially attractive options to meet the nation’s future energy demands.

The downfall of two leading marine- energy developers is damping hope that the emerging industry, which has already lost almost $1 billion, will ever get the technology to market.

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.

Warren Buffett wants to tell you the best time to wash your clothes. Or at least his energy company in the U.K does. Buffett’s Northern Powergrid Holdings Co. is working with Siemens AG to test a so-called smart grid that has the ability to control when consumer appliances will be used in the home.

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."

Japan’s trade ministry is setting stricter rules for production and sales of renewable energy in what it says is a drive to speed up development of projects and ensure stable power supply.

The Detroit Power Outage brought eight hours of hardship to Detroit on Dec. 2 — hardship that could have been averted with microgrids.

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.

The last two months have not been kind to clean energy stocks. Most commentators attribute the weakness to declining oil prices and the Republicans' strong showing in the midterm elections.

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

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.

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 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.

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.

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.

Labor, business, and environmental leaders have formed a unique coalition that will urge Illinois lawmakers to pass new standards for energy efficiency and renewable energy, leading to tens of thousands of new, local jobs.

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.

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.

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.

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.

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.

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.

U.K. electricity from low-carbon sources accounted for almost a quarter of the country’s generation in the fourth quarter as Drax Group Plc converted a second coal-power plant to burn wood.

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.

Investors have spent more than $2 trillion on clean-energy plants in the past decade and last year added more renewable capacity than ever before.

Jim Keffer is Republican state lawmaker in Texas with a permit to carry a concealed weapon and doubts about whether human activity is causing global warming.

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.

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.

The World Bank indicated in its new report "Building Competitive Green Industries: The Climate and Clean Technology Opportunity for Developing Countries" that small and medium-sized enterprises (SMEs) in developing countries are set to undergo significant growth and create more jobs in the field of clean technology. Anabel Gonzalez, senior director for the World Bank's Global Practice on Trade and Competitiveness, said developing home-grown clean-tech industries will help developing countries more effectively increase the adoption of low-cost clean energy and drive sustainable economic development.
