Carbon Separation and Capture for Power Generation: Searching for the Holy Grail

If there is a Holy Grail of efforts around the world to maintain coal in the power generation mixes of electric utilities, the technologies offering a way to separate and capture carbon dioxide have long been at the top of scientists’ and policymakers’ agendas. But for all the attention, and the public and private dollars […]

With Obama’s win, cleaner energy has another chance, but these questions loom

Just because President Obama won four more years, doesn’t mean the next four will be any easier. Sure, it’s now his legacy he is beginning to focus on. But there are tall hurdles even the election results will do to change. Renewable energy developers and suppliers have a few rays of sunshine and a more […]

10 reasons to create a carbon tax

The possible revival of serious talks about a U.S. carbon tax should take thought-leaders to the most recent credible analysis in a book finished earlier this year by Shi-Ling Hsu,  a professor at the University of British Columbia: The Case for a Carbon Tax. Here I cut to the chase to spotlight the 10 reasons […]

Federal Court’s Upholding EPA on Greenhouse Gases Boosts Opportunity for Hybrids and Power from Renewables and Natural Gas

A federal appeals court has done for natural gas and renewable sources of electricity that no executive branch stimulus package could ever hope to do: raise the bar higher still to justify building another coal-fired power plant in the U.S. The same can be said in favor of hybrid and all-electric passenger cars. Now that […]

Low natural gas prices are driving coal gasification out of business

Here we have yet another example of less expensive energy trumping efforts not only to use home-grown energy but technologies built and designed by local or regional companies that create local jobs. What toll this trend will take on America’s clean energy landscape already is being felt wherever cleaner energy policies were enacted. How much a recovering economy and slow this trend is front-of-mind for just about everybody in the clean tech space.

Tax toxins – not carbon dioxide – from coal-fired power plants

Buried inside Robert Bryce’s relatively new book entitled Power Hungry is a call to “aggressively pursue taxes or caps on the emissions of neurotoxins, particularly those that come from burning coal” to generate electricity such as mercury and lead. This is notable not because Bryce agrees with many environmental and human health experts, but also […]

Fallout from Japan’s nuclear crisis

How will Japan fill the gap left by disabled nuclear power plants? And how will other countries with nuclear power plants react to risks posed by  GE’s boiling water reactors in earthquake-prone regions? The answers may not be known for weeks, or months. But as the earthquake damage assessments become more credible, some implications are […]

Coal’s health costs at least $140 billion per year: ‘heads in the sand’

How many credible studies will it take before elected officials and regulators acknowledge that coal has a quantifiable, net negative, impact on the health of human beings and the U.S. economy? The latest study, from the Harvard Medical School’s Center for Health and the Global Environment does a credible and persuasive job of estimating the […]

Searching for the most compelling clean energy innovators

Wherever one looks, from China to India to Denmark to the United States, the race to innovate to a cleaner energy future is on. The more President Obama talks about clean energy nnovation the more U.S. seems to be losing the race because other nations are already very busy at this or are racing ahead. Or are they? […]

A U.S. clean energy standard could bridge partisan divide

Given the widening divide between proponents and opponents of a bonafide national renewable electricity standard / requirement, a discussion is expanding about roles for a “clean energy standard,” or CES. This trek is fraught with gamesmanship that could sully the definition of what is “clean” and what isn’t. But maybe this is moot now. A […]
