Green Energy Risks

Some citizens who are concerned about the long-term viability of the electric grid will no doubt want to purchase their own solar systems with inverters and back-up batteries. I won't discourage those who want to do this–the systems may prove to be of assistance. But I see no reason to subsidize these purchases.[read more]

Want Green Power? Try Community Choice Aggregation

October 29, 2014 by Christine Hertzog

Community Choice Aggregation (CCA) or municipal aggregation, is defined as an energy policy that can promote distributed and/or renewables generation through community-based contracts with electricity suppliers. The community acts as an aggregator, and residents within it are automatically part of that CCA.[read more]

The Two Energy Revolutions Are Progressing in Tandem

September 22, 2014 by Geoffrey Styles

Last year I wrote about the two major energy revolutions happening globally, the shale revolution--mainly in the US--and the renewable energy revolution, focused more on technologies than geography but with big concentrations in Europe and increasingly Asia and the Americas.[read more]

Let's Glocalize! It's a Green Bonding Moment

June 19, 2014 by Clare Taylor

Local authorities are taking an increasingly active role in a clean energy future. Their biggest worry is financing. One way is outsourcing to energy service companies, another is crowdfunding. But perhaps the most effective method to raise substantial money is by giving out municipal bonds.[read more]

Green Gas and Intermittency

Albert van der Molen recently faced a quandary. As Innovation Leader for Stedin, the third-largest grid operator in the Netherlands, his job includes improving electricity and natural gas delivery while expanding the utility’s use of renewable energy.[read more]

Dueling Charts of the Day: Peaker Plants vs. Green Power

Peaker Plants and Green Power

Wind and solar power are transitioning from marginal to central players in the grid energy landscape. But wind and solar are also subject to the vagaries of daily and seasonal weather patterns, which means they sometimes can't be relied on to meet the grid’s critical needs.[read more]

The (not so) green energy race

September 2, 2010 by David Hone

Pick up almost any mainstream media publication today and there will doubtless be a story about the “green race”, the rapid growth of investment in renewable energy, sustainable transport and energy efficiency. It is certainly true that these areas have seen a stunning upswing in recent years, often backed by government mandates, fiscal support mechanisms and in some places a carbon price, but there is also another reality in play.[read more]

The world is at a crucial moment in the battle against runaway climate change. Entire populations and ecosystems are threatened by climate change impacts including drought, heat waves, fires, floods, storms and rising sea levels. World leaders will meet in Copenhagen, Denmark this December to negotiate the next phase of a global climate...[read more]

Wake-Up Call

September 28, 2009 by Geoffrey Styles

In his column in Sunday's New York Times, Tom Friedman highlighted the growth of renewable energy in China and proposed that it represented "The New Sputnik"--referring to the wake-up call this country received when the Soviet Union orbited the world's first satellite in 1957. As is so often the case when Mr. Friedman turns his...[read more]

Nuclear Power as Green Power? Debate Will Heat Up as U.S. Eases Permitting Process

September 20, 2007 by Stephen Del Percio

Currently, 439 nuclear reactors in 31 nations supply 15 percent of global electricity, and 31 new plants are currently under construction throughout the world, including in Finland- Europe’s first in 15 years. Last week, in a fascinating and expansive cover piece on nuclear power’s “new age,” The Economist reported a projection that...[read more]
