March Webinar: Ocean Thermal Energy Conversion

craigshieldsPosted on March 6, 2012 Posted in Ocean Thermal

I hope you can join me for our webinar in March, in which I’ll interview Jim Greenberg, Chief Strategy and Marketing Officer of Ocean Thermal Energy Corporation. I first met Jim on my last trip to the East Coast, and I was immediately impressed with the executive team, the board of advisors, and the basic thoroughness and professionalism with which this organization forwards the OTEC concept.

Jim will discuss his company’s pilot projects in both the Pacific Ocean and Caribbean Sea, and cover the potential that OTEC holds, especially for island nations in tropical waters. I hope you’ll be able to carve out time for this fast-paced conversation, Thursday, March 22nd, at 10 AM PST (1 PM EST)

Here’s the sign-up form: http://2greenenergy.com/free-webinar/.

Infographic on Solar Energy

craigshieldsPosted on March 6, 2012 Posted in Solar Thermal

Here’s another in our ongoing series of infographics, designed to offer young people and clean energy newcomers an accessible introduction to the subject. Here, we provide an objective look at the “pros and cons” of solar.

While we advocate in favor of solar generally, we believe that it’s best to arm people with the unvarnished facts, one of which is “there is no such thing as a free lunch,” i.e., all forms of energy generation come with certain costs and other downsides. It’s by understanding the totality of these facts that one becomes able to have a meaningful, informed, and relevant discussion on the subject.

A Few Words on the Keystone XL Pipeline from Jim Hightower

craigshieldsPosted on March 6, 2012 Posted in Fossil Fuels

Supporters of the Keystone XL pipeline project may want to read this excellent piece by Jim Hightower, radio commentator, writer, and public speaker. The concept that the oil companies who are working so hard to make this happen are doing so for your benefit or mine is ridiculous – a point that Hightower makes with his classic populist style.

“Is Renewable Really Doable?” on Television

craigshieldsPosted on March 6, 2012 Posted in Renewables - Business

I’m shooting a television show on Wednesday whose producer wants me to speak on my new book: Is Renewable Really Doable? In preparation, he asked me for the main topics I’d like to address. I replied that we could get into the meat of the book:

• What the world’s biggest governments are doing to accelerate – and retard – the adoption of clean energy.

• How venture capitalists think with respect to clean energy start-ups.

• How pure and unbiased the thinking of the scientific community actually is.

• What the world will probably be like in ten years? 50 years.

• How the credit crunch and the end of cheap oil will affect us all.

But, while I think 2GreenEnergy readers will be absorbed by these conversations, I have to think that most people tuning into some TV channel might find this too esoteric and off-putting.

I told him, “When I go on most TV and radio shows, I talk about the basic issues: the tough realities, i.e., the technological, and the economic/political issues that make the clean energy discussion such a battleground. What exactly is renewable energy? Why is it better than extracting and burning fossil fuels? If there are good reasons for making the transition (which there are) – even though it comes at an expense, why isn’t it happening? This is much better fare for a general audience, so let’s go with this more simplified subject matter.”

I hope I’m right here. We’ll see.

The Pros and Cons of Wind Power

craigshieldsPosted on March 5, 2012 Posted in Wind Energy

[youtube http://www.youtube.com/watch?v=yQENswF5QQ0&w=500&h=284]

Here’s a short video I made explaining the basics of wind energy for young people, or newcomers to the subject. I explain why the wind blows, offer a brief history of man’s attempts to harness wind energy, and discuss our current efforts to use wind to generate large amounts of electricity with relatively little environmental impact.

From Guest-Blogger Joshua Okomo: A Nation Going Green Is Growing Jobs

craigshieldsPosted on March 5, 2012 Posted in Renewables - Business

Renewable energy investment is not only for energy deployment and world ecology management, it is also for jobs. Nations can choose ruthless economic growth when economic growth is never accompanied by democracy, empowerment and human rights or fruitless economic growth when growth is accompanied by reducing job opportunities.

Throughout the world availability of good jobs is the cheapest way to create human development, enlarging peoples choices to live a long , decent and productive life. Renewable energy technologies create more jobs per megawatt of power generated, and per dollar invested in construction, manufacturing and installation as compared to coal or natural gas. (more…)

Losing Patience with Concepts That Violate the Laws of Physics

craigshieldsPosted on March 4, 2012 Posted in Renewables - Science

I often write here that I’m never nasty or condescending to anyone who submits a business plan, regardless of how asinine their ideas. I have an admission to make: while that was true early, on, it’s no longer the case. Now, I get descriptions of perpetual motion machines and other theoretically impossible devices at the rate of approximately once a week. Each “inventor’ has one curious trait in common: he’s looking for that last couple hundred thousand dollars of investment capital to build a prototype.

True, a few years ago, I had the patience of Job with respect to garbage like this, but it’s wearing thin. I told one guy recently:

Though I don’t know anything about the securities laws in – (wherever he was from; I don’t remember) if you raise money from people here in the U.S., you’ll very likely wind up in prison.

He wrote back tersely: “I don’t need you.” LOL.

Just now, someone wrote me from Armenia with a detailed description of a machine that makes electricity from compressed air (somehow omitting the source of the energy that was required to compress the air). I spent several minutes of my (finite) life reading this, before responding:

Sorry, what you’re describing violates the laws of physics. I’m not saying you won’t be able to find investors, just that you’ll need to target people who lack even the most basic education. Don’t fret though; that’s not too great a challenge in today’s world.

See? I can be both nasty AND condescending. Just thought I’d get that off my chest.

Considering the Externalities of Fossil Fuels, Renewable Energy Is the Bargain of the Century

craigshieldsPosted on March 4, 2012 Posted in Fossil Fuels

As readers may have noticed, I’ve begun promoting the launch of my second book, Is Renewable Really Doable? (available March 15th) using the 32-page report “Insights into LCOE – The Levelized Cost of Energy” as a give-away.

In response to my mentioning the LCOE concept, Henk Daalder responds:

No, we do not need to know what it costs to get sustainable energy, because the fossil route is always more expensive than the sustainable route. (more…)

Thanks to Nate Hagens, Ph.D. For His Contribution to “Is Renewable Really Doable?”

craigshieldsPosted on March 4, 2012 Posted in Renewables - Science

Nate Hagens is a well-known authority on issues related to global resource depletion. Until recently he was lead editor of The Oil Drum, one of the most popular and highly-respected websites for analysis and discussion of global energy supplies and the future implications of energy decline.

Shortly after we were introduced, Nate suggested that I attend a small, private conference at the Aspen Institute in Washington D.C., at which he and some colleagues made a two-hour presentation to about 30 representatives of various NGOs. I was honored, and overwhelmed to be in the presence of so many brilliant people. As I told them as I was leaving the lovely reception that followed, “Sorry, I have to catch a train. And besides, I’ve absorbed as much as I possibly can in one day. My brain hurts.”

I am very grateful to Nate for his help with the project, and I know readers will find his insights quite enlightening.

Do Biofuels Hold the Promise They Claim?

craigshieldsPosted on March 3, 2012 Posted in Biomass

I’m one of these people who essentially runs his life off his “to-do” list — a list of incomplete actions in a Word file that is always open, to which I’m constantly adding, deleting, and reprioritizing.

Here’s something I’ve looked at every day for the last few weeks:

Identify and support a few of the top players in biofuels. Short list: Enerkem, LanzaTech, ZeaChem, Virent Energy Systems, Sapphire Energy, Coskata, Terrabon, Mascoma, Cobalt Technologies, Joule Unlimited, Genomatica, Algenol, SG Biofuels.

I suppose I really DO need to do this, but I’m dreading the task. (more…)
