A Closer Look at Fossil and Renewable Energy Subsidies

By Susan Kraemer, Contributor
Published on June 10, 2015

A new study by the International Monetary Fund puts the total cost of fossil fuel subsidies at approximately $10 million a minute globally, when health costs and environmental degradation are included, never mind the effects of a destabilized climate in future centuries.

The most perverse of these subsidies are aimed at finding new reserves of oil, gas and coal, even though it is generally understood that these must be left in the ground if we are to avoid catastrophic irreversible climate change.

Uncovering Green Alternative Energy Mutual Funds

By Harris Roen
Published on January 20, 2015

Not all alternative energy mutual funds are created equal. In a recent interview with the Wall Street Journal, a reporter asked me which alternative energy mutual funds were the most focused on renewables, noting that many mutual funds hold non-energy related companies such as Apple, PepsiCo and Google. The answer to this question is not as straight forward as one might think. This article sorts out which mutual funds are truly invested in the dynamic and growing green energy sector, and which ones are more peripheral.

renewable energyIlias Tsagas’ report on solar policy in Spain highlights the struggle the rooftop solar industry is experiencing as it tries to demonstrate its value for the power grid.

Spain Approves ‘Sun Tax,’ Discriminates Against Solar PV

By Ilias Tsagas
Published on October 23, 2015

Until recently, Spain had a very general self-consumption policy framework that applied to both grid-connected and off-grid systems. This month though, Spain’s Council of Ministers approved a new self-consumption law that has set the country’s solar advocates up in arms with the government. 

The main problem with the new law, say solar advocates, is that it taxes self-consumption PV installations even for the electricity they produce for their own use and don’t feed into the grid. Spain’s PV sector calls the new law a ‘sun tax.’

Will Solar Plunge Off the Tax Credit Cliff?

By Pamela Cargill
Published February 20, 2015

The Federal Investment Tax Credit (ITC) is set to expire at the end of 2016 — and if it does, residential solar may be in trouble. “The ITC is the swing factor for homeowners — the plunge from 30 percent to zero will dramatically slow down sales for customer-owned systems,” opined Barry Cinnamon, CEO of Cinnamon Solar.

On top of this, many local solar rebates are declining or sunsetting altogether, leaving the ITC as one of the last remaining solar incentives. Net energy metering (NEM) — another kind of incentive — is also under fire in many utility jurisdictions as witnessed in a number of high-profile battles since 2011. (See Vote Solar’s website Our Solar Rights for more on NEM battles nationwide.)

Photoessay: A Day in the Life of a Wind Farm Operator

By Christine Duval, First Wind
Published on January 23, 2015

Have you ever wondered what it takes to run a wind farm? You’ve seen all the amazing photos taken from the tops of turbines, but do you know what the technician is actually doing up there?

A photographer followed around the crew at the Bull Hill Wind farm in Maine. Here’s a glimpse into their daily lives on the job.

Seven Reasons Cheap Oil Can’t Stop Renewables Now

By Tom Randall
Published on January 30, 2015

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.

Here are seven reasons why humanity’s transition to cleaner energy won’t be sidetracked by cheap oil.

1. The Sun Doesn’t Compete With Oil

Oil is for cars; renewables are for electricity. The two don’t really compete. Oil is just too expensive to power the grid, even with prices well below $50 a barrel.

Instead, solar competes with coal, natural gas, hydro, and nuclear power. Solar, the newest to the mix, makes up less than 1 percent of the electricity market today but will be the world’s biggest single source by 2050, according to the International Energy Agency. Demand is so strong that the biggest limit to installations this year may be the availability of panels.

renewable energyIn this review of a renewable energy/physics course, Ann Kenda shares what it’s like to learn about Professor Arango’s sustainable energy home project.

Professor’s Solar-Powered Passive House a Real-life Physics Lesson

By Ann Kenda, Mount Holyoke College
Published on January 9, 2015

Assistant Professor of Physics Alexi Arango has been telling students in his Renewable Energy class for years about a little house in Maine that’s so energy efficient that it heats itself without a furnace.

The home of physics professor Alexi Arango operates entirely by solar power.

“I love the reaction,” he said of students in the physics and environmental studies course, which is open to all majors. “There’s disbelief, and the concept almost seems magical. Then you go through it and talk about the physics, and it’s really not some wild idea.”

Ten Clean Energy Stocks For 2015: Riding The Storm

By Tom Konrad
Published on July 6, 2015

The first half of 2015 saw a mild advance in the broad market, but concerns about rising interest rates and the ongoing Greek debt drama sent income stocks, clean energy, and most non-US currencies down decisively. My Ten Clean Energy Stocks for 2015 model portfolio has heavy exposure to not only clean energy, but income stocks (6 out of 10) and foreign stocks (4 out of 10.)  Despite this the stormy market for all three, the portfolio delivered admirably.

Tesla CTO: Bulk Energy Storage Will Grow Much Faster Than People Expect

By Jennifer Runyon, Chief Editor, RenewableEnergyWorld.com
Published on July 14, 2015

At the standing-room-only opening keynote at Intersolar 2015, all the talk was on the future of solar and how energy storage was helping to pave the way for greater adoption of it. Dr. Eicke R. Weber, the director of the Fraunhofer Institute for Solar Energy Systems (ISE) opened the show outlining the great progress that solar has made in the past two years by stabilizing supply and demand. “Therefore in 2016, 17, 18 you will see production capacity and the market catch up, which means we should not expect further falling prices for PV modules,” he said, adding “You can expect stable prices and maybe even some modest increases.”

What Americans Think About Climate Change in Seven Maps

By Eric Roston
Published on April 7, 2015

Researchers at Yale have unveiled a new interactive map that estimates public opinion on global warming right down to the county level.

As a nation, 63 percent of Americans believe that the globe is warming. (Note: It is.) But that single statistic reveals little about what people in different states, local communities, and congressional districts think. The research, which was published today in the journal Nature Climate Change, makes estimates for those geographies and asks: 

  • Whether people believe humans are causing most of the warming (Note: They are.)
  • If people are aware that scientists understand the world is warming. 
  • What implications of the warming may be: Are people afraid? For themselves? For people in developing countries? For the future? Should we fund renewables, regulate carbon, or do something else?
