The University of Washington’s Dr. Brian Polagye contributed to the book’s chapter on hydrokinetics.

His work focuses on responsibly harnessing the kinetic energy in moving water, in particular, developing a better understanding of the practically recoverable resource for tidal streams. He says, “There is no one energy solution that gets you all the way there. I mean, you wouldn’t legitimately expect to replace all the power we currently consume with a single source like in-stream river hydrokinetics. That being said, I think that river, tidal, wave, ocean current, all of these can make a valuable contribution, either nationally or regionally, to the electric grid. So I think it’s important not to discard an idea simply because it doesn’t solve all of our problems.”

Paul Thomsen, spokesperson for Ormat Technologies, provided the book’s chapter on geothermal, discussing his company’s power plants that are a field-proven, mature commercial product operating worldwide.

The first geothermal project was about 1905 in Italy. A farmer drilled a well, hot water came out, which turned to steam and the concept of putting a steam turbine on that to produce electricity was created. Soon we had flash technology, where water comes out of the ground, turns to steam and you put a turbine on it. And there are projects like that in Northern California at the geysers; there are projects like that in Iceland, in Africa – but they tend to be unique anomalies.

Ormat Technologies became a company in 1965. Our chairman decided that there were probably more stable ways to produce electricity and started to work on a heat exchanger and a turbine design utilizing what’s called the organic Rankine cycle. The cycle simply creates a secondary loop; where there are deviations in temperature, you can heat a working fluid which does the vaporizing, which builds pressure and turns a turbine. He first implemented this on a solar project in Mali, Africa. It was technically a success, but commercially not that attractive, so he turned towards geothermal.

Dr. Mills, known worldwide for pioneering Compact Linear Fresnel Reflector (CLFR) technology and for his work over the past 30 years in non-imaging optics, solar thermal energy, and PV systems, contributed to the book’s chapter on solar thermal.

This chapter addresses the notion of scale.  Dr. Mills believes wind and solar can all scale to be very large; each of them has the capability to take on the entire electricity load. But the question is how much does that cost and do they do it in a way where we have reliable energy?

Bruce Allen is supremely well-qualified to have contibuted to the book’s chapter on photovoltaics.  His recent book Reaching the Solar Tipping Point describes the key technologies and applications that are enabling solar energy to become a primary cost-effective energy source. He has designed solar concentrator systems sold worldwide and worked at the Jet Propulsion Laboratory, under contract to NASA, DOD and the US Missile Defense Agency.

Dr. Amir Mikhail, Clipper’s senior vice president of engineering, contibuted to the book’s chapter on wind. Clipper Windpower is one of the most visible organizations on Earth in the race to provide solutions that offer utility-scale clean energy. The company strives to advance the technologies and services that make its customers successful in the expansion of wind energy, lessening the impacts of fossil fuel generation.

Dr. Mitchell contibuted to the book’s chapter on algae as biofuel. 

Fundamentally, the photosynthetic process reduces inorganic compounds like carbon dioxide, water, nitrogen, and phosphorous, and builds these biochemicals. Initially sugar, and then the sugar’s burned to build all sorts of other things, and nutrients are brought in and you build membranes with phosphorous and you build proteins with nitrogen and so forth. It is all ultimately derived out of the sunlight.

The World Resources Institute’s Vice President for External Relations Robin Murphy contributed to the book’s chapter on the role of NGO in the migration to clean energy.  WRI assists leaders in both the private and public sectors in making sound decisions with respect to practices that affect our environment, working at the intersection of environment and human needs. WRI’s mission is to provide analysis, research and recommendations, that will help advance sound environmental decisions. And those are decisions made by leaders in business, leaders in government, leaders in fellow NGO’s – non-profits around the world, in academia and elsewhere.

Johanna Wald contributed to the book’s chapter on litigation – using the court system to force public and private entities to conform to laws that are in place to protect the people and the planet we call home.

There are many parts of NRDC. And certainly a watchdog function, as I think of it, has been traditionally and historically a big part of our activities. My work, in particular, has been in opposition to fossil fuel development on public lands. I’ve been at NRDC for more than 35 years now; my whole career has been devoted to defending the federal public lands – those that are managed by the Parks Service, the Bureau of Land Management, the Forest Service, and so forth. While I am also trying to prevent harmful and irresponsible renewable development, I am at the same time affirmatively trying to promote well-sited development.

Leadership action that Vectoris following was announced shortly after Obama’s Oval Office speech. It comes from former Senator Tom Daschle (Senior Fellow at the Center for American Progress) and a coalition of clean energy industries. Coalition members include, among others, the American Wind Energy Association, the Business Council for Sustainable Energy, the Biomass Power Association, the Geothermal Energy Association and the Solar Energy Industries Association.

At a press conference on June 23rd, the coalition called on the White House and Senate to take urgent action on legislation for clean energy.        (more…)

The Carbon War Room’s CEO, Jigar Shah, contibuted to the book’s chapter on Free Market Capitalism. Founded by British industrialist and humanitarian Richard Branson, the Carbon War Room uses the principles of laissez-faire capitalism to deal with the problems brought about by our planet’s addiction to fossil fuels. The organization points out, “Our global industrial and energy systems are built on carbon-based technologies and unsustainable resource demands that threaten to destroy our society and our planet. Massive loss of wealth, expanding poverty and suffering, disastrous climate change, water scarcity, and deforestation are the end results of this broken system. This business-as-usual system represents the greatest threat to the security and prosperity of humanity – a threat that transcends race, ethnicity, national borders, and ideology.”
