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.

More than 100 world leaders converged upon New York City today to discuss international efforts to reduce carbon emissions and combat climate change. The list of speakers at the UN Climate Summit included U.S. President Barack Obama, UK Prime Minister David Cameron, Brazilian President Dilma Rousseff, French President François Hollande, and Chinese Vice Premier Zhang Gaoli.

California and Quebec, which together created the largest carbon market in North America this year, may come away empty-handed as they woo northeastern U.S. states to join their system.

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.

The European Union is seeking to speed up the creation of a common energy market to help its shift to a low-carbon economy and boost security of energy supplies amid a natural-gas dispute between Russia and Ukraine.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Global investment in clean energy slumped 15 percent in the first quarter to the lowest level in two years because of a decline in wind and utility-scale projects.

Clean water — it’s a precious resource in hot demand right now, for more than taking a shower or watering our crops. The United Nations projects the world’s population will grow by another billion people, to 8.4 Billion, by 2030. More people means more need for food, water, electricity, and other necessities. Beyond the obvious demands for water, our increasing appetite for electricity also requires water — and plenty of it. Most of the electricity generated in the U.S. uses water in some capacity.

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.

Coal is having a hard time lately. U.S. power plants are switching to natural gas, environmental restrictions are kicking in, and the industry is being derided as the world's No. 1 climate criminal. Prices have crashed, sure, but for a real sense of coal's diminishing prospects, check out what's happening in the bond market.

While it’s well known that corporations were some of the earliest trailblazers of large-scale renewable energy purchasing — they’ve closed over 14 gigawatts of deals in the past six years, according to tracking by Rocky Mountain Institute’s Business Renewables Center — higher education has also made impressive strides. In fact, a report released last fall showed that the top 30 renewable energy-buying universities are using around 3 billion kilowatt-hours of green power annually. That’s enough to power 276,000 homes.
