Energy Vision 2050 - part I

This is a guest post by Sterling Smith (TOD user Sterling). This first installment of the series outlines the evolution of the energy panorama from now to 2050. A second installment will deal with technical and political aspects of the path put forward.



Sterling is a software architect who works in Silicon Valley and lives in Woodside, California. He was born in the suburbs of New York City and graduated from Dartmouth College, where he majored in physics. He has worked in the software business for 35 years, still writes code, and has been part of eleven start-ups as well as several major corporations. Sterling's wife, Deborah Metzger, PhD, MD, is a very prominent gynecologist with whom he is raising four kids.

API Energy IQ Game and Blogger Call

In this post, I will talk about American Petroleum Institute's new Energy IQ Game and a related bloggers call, which Nate Hagens, Robert Rapier, and I participated in.

Last year, the American Petroleum institute (API) developed an Energy IQ Survey. This year, they revised it slightly and made it into a game. You can play, by clicking on this link:

Gore sets goal of 100% carbon-free electricity by 2020

Al Gore has made a major speech in Washington this morning, setting out an ambitious goal for the USA to produce all of its electricity from carbon-free sources by 2020. I thought I'd comment on the technical feasibility of the plan, and the underlying economics of such an endeavour.


from the Department of Energy's recently published study about bringing wind power to 20% of total generation

The short answer is: while 100% is probably unrealistic, it's not unreasonable to expect to be able to get pretty close to that number (say, in the 50-90% range) in that timeframe, and it is very likely that it makes a LOT of sense economically.

Disclosure (or reminder): I am an investment banker for the energy sector. I do a lot of work with the wind sector, as the posts in my wind power series attest, but not only. Whether a pipeline or a wind farm, the job of a project financier is to ensure that the projects make sense for all interested parties (including the regulator) in the long run, and wind projects have to meet the same hurdles as other power plants or oil fields. Thus I'm supposed to remain level-headed when discussing wind projects!

Senate blocks debate of clean energy tax credits

Amazing. (link to article) (Previously discussed at TOD here.)

WASHINGTON (Reuters) - The U.S. Senate on Tuesday blocked debate of a bill to offer about $17.7 billion in tax incentives for consumers to build renewable energy sources like windmills and solar arrays, and buy plug-in cars that run on electricity rather than gasoline.

The Energy Independence and Tax Relief Act of 2008 would have extended a tax credit to build windmills by one year through December 31, 2009, and extend for three years similar credits for renewable energy sources like biomass, geothermal, landfill gas and trash combustion.

Green Cottage: eco-renovation of a 100-year-old Victorian end-terrace

This is a guest post from Andy Hunt (solar_bud on The Oil Drum). It's an inspiring account of what can be done today with a modest property to live efficiently and maintain a degree of energy security.

Vital Statistics

Our house was built around 1900. It is an end-terrace house with 2 bedrooms, located in an inner-city area in Bury, Lancashire, UK. Our household comprises me and my partner, with no children, and we live in the property all year round. No planning restrictions are in effect in our area.

An Update on the Renewable Energy and Energy Efficiency Tax Credits (H.R. 5984, H.R. 6049, and S. 2821)--Rejected, but...

The Senate today rejected the part of House bill H.R. 6049 that would have extended the renewable energy and energy efficiency tax credits that would otherwise expire at the end of this year. (Vote lists under the fold).

However, this is NOT the LAST potential opportunity for this Congress to extend the renewable energy and energy efficiency tax credits which will otherwise expire at the end of 2008. More under the fold.

If Portugal Can Do It, Why Can't We ?

The Guardian has an interesting article on the rapid build-out of renewable energy generation in Portugal. The country seems to be determined to become free of dependency on fossil fuels as soon as possible, with the country's energy minister also sagely pointing out "When you have a programme like this there is no need for nuclear power. Wind and water are our nuclear power".

The country currently has Europe's largest solar power plant, is constructing Europe's largest wind farm and is on the leading edge of research into wave and tidal power. The obvious question is - if Portugal can do this, why can't we ? This applies more to Australia than New Zealand obviously...

Andris Piebalgs' Blog


Andris Piebalgs is the European Energy Commissioner with responsibility for shaping European Union (EU) energy policy. These policies may then be adopted by the European Parliament and will effectively shape Europe's energy future.

Mr Piebalgs has an informative web site where he has newly installed a blog inviting comments on EU energy policy.

I would like to invite all my fellow bloggers and all citizens to contribute your ideas.

Andris, I would like to thank you for providing us bloggers with this wonderful opportunity to relay our ideas and opinions directly into the heart of the European Parliament. But beware, not all ideas and opinions are born equal.

There's more under the fold.....

Powering Civilization to 2050

Global marketed primary energy production 1970-2050. Expressed in thermal equivalent of millions of barrels/oil day (ie electricity streams such as hydro or photovoltaic are treated as if they had been converted from fuel at 38% efficiency). Source: BP for fossil fuel, hydro, and nuclear data, EIA and IEA for renewable data, and author's calculations as described in the text for projections. This is a scenario not a forecast.

Offshore Wind

I spent most of this week at the big conference organised every two years by EWEA (European Wind Energy Association) on offshore wind, which took place in Berlin over this week.
