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.

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.

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.

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.

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.

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.

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.

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.

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.

We've made great progress with renewable energy — but from an almost zero base we still have a long way to go. Fortunately, the path is clear. California is already over 12 percent with a combination of hydroelectric, wind and solar (unfortunately not much hydro this year). Getting to 50 percent only requires the deployment of existing technology. But can we get to 100 percent?

Political deadlock over Australia’s clean energy future is prompting companies such as Vestas Wind Systems A/S and Acciona SA to increasingly turn to rival markets for growth.

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.

Australia’s largest electricity producer committed to close its coal-fired power plants within 35 years as part of an effort to cut the nation’s dependence on the fossil fuel.

Last June, the Environmental Protection Agency (EPA) proposed the first ever national carbon pollution standards for existing power plants. Fossil fuel-fired power plants account for almost 40% of U.S. carbon dioxide emissions, making them the largest source of greenhouse gas emissions in the nation and one of the single largest categories of greenhouse gas sources in the world.

A $2 trillion push in the U.S. to blend renewable energy into the power supply and fortify transmission lines against extreme weather means that Americans must act more like Europeans to keep their power costs down.

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.

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.

Ongoing growth in renewable energy investment and deployment is creating jobs worldwide — and lots of them. This job growth is helping governments address a fundamental economic problem plaguing developed and developing countries alike. Deploying renewables rather than fossil fuel capacity is also reducing greenhouse gas (GHG) emissions and other environmental pollution that holds the threat of a sixth great extinction.

Carbon emissions in 2014 remained at the previous year’s levels of 32.3 billion metric tons — a milestone that points to the impact worldwide renewable energy investment is having in the face of a 1.5 percent annual increase in global energy consumption, according to a new report from REN21. The tenth annual Renewables 2015 Global Status Report cites “increased penetration of renewable energy” and improvements in energy efficiency as the chief reasons for the noted emissions stabilization.

In West Virginia, where workers have harvested coal seams for centuries, Pope Francis’ new warning about the risks of fossil fuels will find skepticism even among the faithful.

Publicly, the United Nations climate-change talks look mired in disputes over everything from money to the length of the proposed agreement.

Here’s a nightmare for you: at night, when you’re asleep and you think things are quiet, there are vampires sucking power out of your house and increasing your electric bill. The fact of the matter is that every plugged in electrical device in your home uses a small amount of standby power -- even if you think these devices are off.

Hawaii Governor David Ige on Aug. 21 joined executives from the Office of Ocean Naval Research (ONR), Makai Ocean Engineering and other organizations on-site at the Natural Energy Laboratory of Hawaii Authority (NELHA) in cutting the ribbon and commissioning the first U.S., and world's largest, grid-connected ocean thermal energy conversion (OTEC) power plant.

The World Bank has approved US$390 million in additional financing to be used by Pakistan's Water and Power Development Authority for extensions of its Tarbela hydroelectric plant.

Power Africa and Trade Africa Coordinator, Andrew Herscowitz, announced on Feb. 14 during the Abuja Electricity Distribution Co.’s two-day Distribution Company Workshop in Abuja, Nigeria, that the U.S. will invest US$1billion in the country through the U.S. Trade and Development Agency (USTDA).

IT Services Giant Offers Update During Quarterly Financial Results Call
Cognizant estimates that the April ransomware attack that affected its internal network will cost the IT services firm between $50 and $70 million in losses, according to the company's latest financial results. Cognizant has said that the Maze ransomware gang is behind the attack.

To those in the climate change field the name Mark Z. Jacobson needs no introduction. The director of the Atmosphere and Energy Program at Stanford University is credited with having written the book on computer modeling for atmospheric changes, as well as being a recognized expert in the impacts of energy production and a staunch supporter of renewables.

In the third quarter, clean energy stocks in general continued their upward trend, turning in a 27 percent gain for the quarter and a 64 percent gain for the year as a whole, as measured by my benchmark and most broadly held clean energy ETF, Powershares Wilderhill Clean Energy (PBW.) This brings PBW back up to levels last seen in September 2011.

Oracle Corp. Chief Executive Officer Larry Ellison plans to build one to power the Hawaiian island he bought last year. EBay Inc. has one to run a data center. The University of California at San Diego and the federal government have invested tens of millions of dollars in the technology.

This month marks the anniversaries of two notable events, decades apart yet related in terms of historical impact, awareness of vulnerability, and challenge to business as usual: the Arab oil embargo 40 years ago (Oct. 19-20, 1973) and Superstorm Sandy, which hit the Northeast on Oct. 29 last year. Both events sparked a national and global focus on two concepts I’ve been hearing quite a bit about in recent months: adaptation and resilience.

One of Europe's largest utilities is on the cusp of reportedly transforming its business from being a centralised energy provider into a decentralized energy provider.

The European Commission has offered up some new guidelines about managing electricity markets among its Member States, offering direction for design and support schemes for renewable energy, managing capacity, and addressing demand at the consumer level to mitigate new generation investments -- which, while technically not binding, likely will inform future regional environmental and aid policies.

Wind farms and solar parks are changing hands at record rates, signaling both an increased taste for the assets among pension funds and hard times for utilities that are the biggest sellers.

In the global competition for appealing clean energy solutions, a leading entry is the new West Village at the University of California at Davis (UC Davis), which today celebrated significant progress toward its goal of becoming the largest planned “zero-net energy” community in the United States.

Nearly one month after Typhoon Haiyan ravaged the Philippines, affecting more than 12 million people and killing almost 6,000, many residents are still sitting in the dark. The Superstorm not only decimated the islands’ transmission systems, it knocked out one of its main power sources — geothermal.

The United States broke one record after another for extreme weather in 2013. From deadly floods in Colorado to prolonged drought across the Southwest, Americans saw what unchecked climate change can do to our communities. But we also witnessed another kind of powerful force: real and positive climate action.

Prime Minister David Cameron urged the European Commission to reject calls for a renewable energy target, saying such a plan may cost U.K. consumers 9 billion pounds ($14.8 billion) a year by 2030.

The European Union is poised to take its first formal steps to expand the world’s most ambitious limits on fossil fuel pollution. That may widen a rift in how it balances green policies with the need for cheaper power.

Wind and solar power producers say they're at risk of losing investment after the European Union's executive arm scrapped proposals for a mandatory target on renewable energy use in 2030.

Tesla Motors Inc. Chief Executive Officer Elon Musk said shifting to greater use of solar and wind power will challenge utility companies.

The European Union should ensure that future climate and energy policies do not undermine the competitiveness of its industry, already weakened by a price gap with the U.S., the bloc’s member states said.
