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.

Four energy companies are proposing an $8 billion renewable energy project that would supply Los Angeles with more than twice the power generated by the Hoover Dam.

Scotland’s decision to vote no to independence from the United Kingdom of Great Britain and Northern Ireland has elicited a collective sigh of relief from energy sector players. Those companies with significant investments in Scottish renewable energy assets had understandably been anxious over the uncertainty that an independent Scotland would engender, for example potentially changing the rules on support measures for renewable energy investment north of the border.

As a businessman exploring investments, I need simple answers, however complicated the problem. I wish to know: Are microgrids economical? How much investment is needed and for what? What are the factors that principally affect profitability, within the system and in the environment? If microgrids are not profitable at the present, when will they be? I recognize that understanding microgrids as a system requires complicated mathematics and modeling. I’m sympathetic to and respect those who do that.

Renewables became Germany’s most important power source for the first time this year, according to Agora Energiewende.

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.

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.

The green revolution and, in particular, renewable energy products such as solar power, wind turbines, geothermal and algae-based fuels are not waiting for viable technology — it already exists in many forms. What they are waiting for is a massive sea change in our antiquated financial accounting systems.

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.

As more intermittent renewable capacity is added to grid networks around the world, the need for greater system flexibility in order to cope with the variable supply is growing. In parts of the Europe, grid operators complain that balancing the system is becoming more and more difficult as new renewable sources are added, requiring ever more complex management techniques, as well as repeated use of polluting and inefficient standby capacity. Surges of solar and wind power are often not fully utilised, causing some to question the wisdom of adding further variable renewable capacity.

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.

The U.S. expects to earn $5 billion to $6 billion from a federal loan program, bolstering President Barack Obama’s decision to back low-carbon technologies.

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.

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.

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.

Technology and equipment giant Siemens AG has decided to sell its tidal energy company, Marine Current Turbines Ltd., citing slow development in the marine and hydrokinetics sector.

The news about the Environmental Protection Agency’s plan to limit carbon pollution from existing power plants just got even better: the proposed Clean Power Plan (CPP) can save the power industry and its customers — us — as much as $2 to $4 billion in 2020 and $6 to 9 billion in 2030, while cleaning our air and modernizing the electricity sector.

The power sector crisis in Japan has entered a new stage. The recent refusal of Japanese utilities to grant grid access to new renewable energy projects should not be seen as a failure of Japan’s renewable energy policy, but as a consequential and necessary phase to extend Japan’s technological leadership into the power sector.

The Brazilian government is seeking to award contracts in an auction tomorrow for natural gas- and coal-fueled power plants, reversing a drive that previously favored renewable-energy projects. It would lead to the first new thermal plants in three years, after the government scaled back such projects and awarded wind contracts starting in 2009 and solar energy earlier this year.

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 California Energy Commission (CEC) and U.S. Navy (USN) are teaming up to spur deployment of grid-integrated local renewable energy resources and advanced energy storage solutions. On December 1, Imergy Power Systems announced that its ESP30 series vanadium-flow batteries will be used in a CEC-sponsored Smart Microgrid project hosted by the Navy at its Mobile Utilities Support Equipment (MUSE) Facility in Port Hueneme, California.

Germany’s biggest utility E.ON — long a pillar of the country’s fossil fuel and nuclear industry — dropped a bombshell on Europe’s business world with the announcement that the multinational was exiting the conventional energy market in favor of a new business model based on renewables, intelligent grid systems, energy management and other services. Indeed, the company seems finally to have drawn the logical consequences from the Energiewende, Germany’s renewable energy transition, after years of resisting the ambitious transformation of the nation’s energy supply.

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.

India, the world’s third-largest polluter, will spend at least $100 billion on climate-related projects but isn’t ready to follow China and the U.S., the top two emitters, in promising to limit its fossil-fuel emissions.

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.

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."

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.

Developers, manufacturers, investors and other renewable energy industry stakeholders need updates on the latest and greatest finance mechanisms available today. Since 2003, global consultancy Ernst & Young has released its Country Attractiveness Indices, which ranks global renewable energy markets by analyzing investment strategies and resource availability.

Developers, manufacturers, investors and other renewable energy industry stakeholders need to know where the next big market is going to be so that they can adjust their business decisions accordingly.

The online community of readers who visit RenewableEnergyWorld.com is an important aspect of the news and information that we offer renewable energy stakeholders. 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.

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.

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.

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.

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.

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.
