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.

Pope Francis turned a keen eye toward the environment and the problem of climate change with his encyclical,“Laudato Si” (“Praised Be”). As a clean energy advocate, I’m heartened that Pope Francis recognizes the need to transform our energy system.

Trillions of dollars will be invested in renewable energy over the next 25 years, driving some of the most profound changes yet in how humans get their electricity. That's according to a new forecast by Bloomberg New Energy Finance that plots out global power markets to 2040. 

German Economy Minister Sigmar Gabriel said 13 percent of power stations burning lignite, a cheap form of coal, would be phased out by 2021 under a program to cut power industry pollution. The government abandoned talks on proposals to impose a climate-change fee that the industry said would have forced mines and plants to close, threatening jobs.

This month alone, we Americans celebrated our nation’s birthday, capped off perfectly by the USA women’s soccer team’s sensational 5-2 victory in the World Cup final. As we hit the halfway point of 2015, the clean-energy industry also has much to celebrate, much of it in the month of June alone and much of it financial.

In a lopsided 23-3 vote, the U.S. Senate Finance Committee voted yesterday to extend a number of renewable energy production tax credits through the end of 2016. The vote allows developers of wind, geothermal, biomass, landfill gas, incremental hydroelectric, and ocean energy to take advantage of federal tax credits for projects begun before December 31, 2016.

Chief among big renewable winners was the wind energy industry, which received extensions to the Production Tax Credit (PTC) and the Investment Tax Credit (ITC). If passed, wind farms would qualify for a 2.3-cent-per-kilowatt-hour (kWh) credit through the end of 2016.

Executives from 13 major U.S. corporations are announcing at least $140 billion in new investments to decrease their carbon footprints as part of a White House initiative to recruit private commitments ahead of a United Nations climate-change summit later this year in Paris.

Companies including Apple Inc., Berkshire Hathaway Energy Co., and Goldman Sachs Group Inc. will join Secretary of State John Kerry and top administration officials at the White House for the announcement. In addition to pledges to cut emissions, provide financing to environmentally-focused companies, and reduce water consumption, the companies have said they will procure at least 1,600 MW of new, renewable energy. The White House said in a statement that it expects to announce a second round of similar pledges later this fall from additional companies.

The commitments are being announced as President Barack Obama is looking to build momentum toward a legacy-defining global climate accord in Paris. In addition to company-specific commitments, the corporate leaders on Monday will signal their support for a strong climate agreement out of the United Nations talks. They administration is using the pledges to set an example for companies to find ways to eliminate their carbon emissions.

Climate Talks

“As the world looks toward global climate negotiations in Paris this December, American leadership at all levels will be essential,” the White House said in a fact sheet detailing the announcement.

The administration’s actions are pushing the issue into the 2016 presidential debate. Hillary Clinton, the front-runner for the Democratic nomination, released an energy strategy saying she would both defend and go beyond Obama’s efforts. Republican candidates have criticized the administration’s initiatives as costly to the economy and unnecessary.

Among the pledges, aluminum manufacturer Alcoa Inc. has agreed to reduce emissions by 50 percent from its 2005 levels, while agricultural giant Cargill Inc. says 18 percent of its total energy use will come from renewable sources.

Coca-Cola Co. said it would drive down the carbon footprint of its beverage production by 25 percent over the next five years, while Google says it plans to triple its purchases of renewable energy over the next decade. Berkshire Hathaway says it plans to invest up to an additional $15 billion in the construction and operation of renewable energy generators, while Bank of America Corp says it will increase its environmental business initiative by $75 billion over the next decade, according to the White House

Other participating firms include Wal-Mart, United Parcel Service Inc., PepsiCo Inc., Microsoft Corp., General Motors Inc.

The corporate commitments won’t be the administration’s only major climate announcement in the next few weeks. The Environmental Protection Agency is set to present final regulations that aim to reduce carbon emissions from power plants by 30 percent from 2005 levels by 2030 later this week.

While visiting Kenya over the weekend, Obama repeatedly praised the country for its efforts to address climate change, saying its efforts tor educe emissions “has put it in the position of being a leader on the continent.” And next month, the president will travel to Alaska for an international summit on Arctic climate issues.

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.

More than a year after Prime Minister David Cameron publicly announced support for the Perpetuus Tidal Energy Center (PTEC), Great Britain’s Marine Management Organization (MMO) issued a license on April 20 to Royal HaskoningDHV to deploy and operate a proposed 30-MW tidal array at the center, located off the Isle of Wight.

Five companies were recognized this week by the National Hydropower Association during its annual Waterpower Week in Washington conference for work in hydroelectric power that exemplifies "extraordinary recreational, historical, environmental or educational value."

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).

Update: On March 2, 2017, U.S. Senators confirmed Rick Perry as the new Secretary of Energy of the United States. The vote was 62-37 with nine democratic senators casting "yes" votes. 

The possibility of producing shale gas in some European countries has triggered a very heated debate about the environmental and social impacts of the technique used to extract gas from shale rocks (today only in the US and Canada); this technique is widely known as hydraulic fracturing or fracking.

So here we are: the U.S. federal government is in shutdown mode after Congress failed to pass the budget. We've seen this several times in the past couple of decades, usually ranging from a few hours to a few days, though the most recent one lasted nearly a month from late 1995 into early January 1996.

Mandatory spending cuts triggered by the March 1st sequester (automatic spending cuts) in the U.S. are being felt across the renewable energy sector sparking fears that reduced federal investment could curtail research, development and commercialization of new renewable energy technologies.

Alternative energy mutual funds (MF) racked up extremely robust gains in the past year. Returns range from a low of 16 percent, to a high of 64 percent for a mutual fund that is heavy into solar investments. Exchange traded funds (ETF) also did well, but returns are much more variable. They range from a loss of 34 percent for a carbon ETF, to more than doubling of a solar ETF.

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.

Geothermal industry leaders say they are losing a popularity contest with wind and solar power, but claim they are offering a better product.

Germany’s power grid operators boosted the surcharge consumers pay for renewable energy by 18 percent to a record, adding to pressure on Chancellor Angela Merkel’s government to act against rising electricity bills.

October 17 marks the 40th anniversary of the start of the 1973 Arab Oil Embargo — an event that arguably launched the United States' ongoing pursuit of a national energy policy.

Coal contributes 60 percent to India's power mix today; solar is less than 1 percent. But what was a factor-of-seven difference between the cost of coal and solar two years ago shrank this summer to just a 1.8x gap. Can solar catch up within the next ten years?

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.

Walk into any panel discussion at a geothermal power event and you will often hear about barriers hindering geothermal development. In spite of the obstacles, the geothermal industry has grown and adapted to adversity, and it is unfortunate when more attention is not given to geothermal power’s technological accomplishments and the long-term potential. Today, 73 countries across the globe are actively engaged with the geothermal energy sector, showing that more governments, utilities, and industry stakeholders are recognizing the long-term value geothermal power can bring to their power systems.

In early 2013, a group of women, dubbed the Women in Power committee, assembled in Orlando, Florida to figure out how to honor women who have dedicated their careers to the power industry. The industry is male-dominated with men making up more than 75 percent of the workforce, according to some estimates. The Women in Power committee believed that it was time to give recognition to the pioneering women who have worked to advance the power industry. To do this, the committee decided to allow anyone in the industry to nominate a woman for a Woman of the Year Award, which would be given out at POWER-GEN International. To judge the nominees, the committee came up with three focus areas.

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 Advanced Research Projects Agency-Energy (ARPA-E) program was officially launched in 2009 as the result of the 2007 America COMPETES Act, which was signed by President George W. Bush. Congress appropriated and President Barack Obama allocated $400 million in 2009 to begin funding the agency’s first projects. ARPA-E exists within the broader organizational framework of the Department of Energy and was modeled after the very successful Defense Advanced Research Projects Agency (DARPA), which has been credited with developing technological innovations such GPS (global positioning system), the stealth fighter jet and more.

The SEC has finally proposed its rules to allow crowd-funding under the Jumpstart Our Business Startups (JOBS) Act. What do they mean for small-scale investments in renewable energy companies and projects?

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.

Canada’s stock exchanges have long had the lead as the place for energy infrastructure companies to list. This includes green energy, as well as the fossil fueled sort. Because Canada’s reporting rules are somewhat less stringent, and its markets less liquid than those in the U.S., the large number of offerings trade at lower valuations and higher yields than do their (few) U.S.-listed equivalents.

StatWeather Founder and President Ria Persad was announced as the recipient of Renewable Energy World and Power Engineering’s first POWER-GEN Woman of the Year Award last Monday during the Annual Awards Gala at POWER-GEN International.

What’s the next big opportunity for geothermal? According to panelists at last week's Renewable Energy World North America international geothermal session, it’s emerging markets. Kicking off the two-hour discussion, special guest Agnes Dasewicz of the U.S. Agency for International Development (USAID) explained the Power Africa initiative, which launched in June 2013. USAID is attempting to unlock energy growth in six countries: Kenya, Tanzania, Ghana, Nigeria, Liberia, and — of particular interest to the geothermal crowd — Ethiopia.

The U.S. brought online nearly 700 MW of new electricity generation in October, and practically all of it was large-scale solar energy, according to data from the Federal Energy Regulatory Commission's (FERC) Office of Energy Projects.

The third quarter earnings season has been quite eventful for my Ten Clean Energy Stocks for 2013 and six alternative picks model portfolios, so much so that writing about them has taken a back seat to keeping up with the announcements. There were a number of earnings disappointments and earnings announcements which were in line with my expectations but the market treated like disappointments. These resulted in an overall decline of 2.5 percent for the portfolio since the last update, even as my industry benchmarks, the Powershares Wilderhill Clean Energy (PBW) and my small cap benchmark (IWM) were up 1.0 percent and 3.9 percent over the months since October 15th.

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.

As we come into the final stretch of 2013, my annual model portfolio of Ten Clean Energy Stocks for 2013 looks certain to break its five year winning streak of beating its industry benchmark. As of December 6th, the model portfolio's total return has been 19.0 percent, compared to a sunny 56.1 percent for my benchmark, the Powershares Wilderhill Clean Energy (PBW). The broad market, as represented by the Russell 2000, also resoundingly beat my model portfolio, and is up 37.5 percent. My six alternative picks fared even worse than my top ten.

Developing countries that are interested in geothermal energy may see transformational results by approaching World Bank and other institutions, as Djibouti did. In an interview, the World Bank Djibouti geothermal project team talks about the project investment, lessons from Kenya’s experience, and preparations that are being made for the private sector to take up the next steps.

It’s easy to get caught up in the holiday bustle: shopping, decorating, parties, and preparation. Our to-do lists can seem endless, but we carry on because it is that special time of year, a season of giving.

For those clamoring for (and against) the year-end-expiring legislation, and anyone in favor of some tax-code simplification, today the government has offered an early holiday present: proposed reform for some key areas including the production tax credit (PTC) and investment tax credit (ITC).

According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, solar, biomass, wind, geothermal, and hydropower "units" provided 394 MW — or 100 percent — of all new electrical generation placed in-service in November 2013. There was no new capacity during the month from natural gas, coal, oil, or nuclear power. Renewable energy sources also provided 99 percent of all new electrical generating capacity in October.
