Two Free Books on Energy (and Ecology) Issues

I want to introduce two amazingly well-written energy (and ecology) books that are freely available online. (Their download links and tables of contents are below.)
I didn't read them all yet. However, from my first impressions from the books, my short description is:
Girardet & Mendonça's book is newer. This book is more concentrating on social issues.
The book by Professor MacKay (pronounced mac-EYE) is covering relatively more technical issues with exhaustively selected data.

Rural Electrification Policies in Brazil, China, India and South Africa

This IEA report is very informative about "country-specific" problem-solving policies taken by four major emerging-economy countries: Brazil, China, India and South Africa.

Niez, A. (2010). Comparative Study on Rural Electrification Policies in Emerging Economies: Keys to Successful Policies. Paris, France: International Energy Agency.

Full-text: http://www.iea.org/papers/2010/rural_elect.pdf

Let us think of these four countries' share of world's energy consumption.

Primary Energy Consumption in 2008

Country Million tonnes oil equivalent Share
Brazil 228.1 2.0%
China 2,002.5 17.7%
India 433.3 3.8%
South Africa 132.3 1.2%
4-Country Total 2,796.2 24.8%
United States 2,299.0 20.4%
European Union 1,728.2 15.3%
OECD 5,508.4 48.8%
Former Soviet Union 1,028.9 9.1%
World Total 11,294.9 100.0%

Pledges for the Copenhagen Accord and "How we can verify actual fulfillment"

Although the UNFCCC posted official documents from the Copenhagen meeting (COP-15), they didn't summarize the pledges of all the participating countries to support the Copenhagen Accord.
All I could find online is this Reuters article.

FACTBOX-Backers of Copenhagen climate deal, 2020 plans
31 Mar 2010 10:54:36 GMT

If you want to read original pledges of nations, you can find them on the UNFCCC's website at
http://unfccc.int/home/items/5262.php
Annex I countries' pledges are neatly compiled in one table.
Non-annex I party's pledges are separately collected as scanned pdf files.

At this point, we can ask, "How can we verify counties' actual commitments to their pledges?"
Here comes an interesting and informative publication from the US National Research Council.

Satisfying 100% of Europe's Electricity Needs by Renewable Sources

PricewaterhouseCoopers, an international accountancy and professional services firm, published an ambitious plan for Europe's energy future. Three research institutes (PIK, IIASA and ECF) have collaborated with PwC.

Their analysis for the plan asserts a pan-European, cross-Mediterranean grid (dubbed SuperSmart Grid) will enable Europe to meet their electricity needs 100% from renewable electricity.

If this kind of geographically optimized power mix is achievable thanks to a high-voltage direct current (HVDC) transmission system, the same is possible in North America.

IEA. (2010). Projected Costs of Generating Electricity - 2010 Edition

Today, the International Energy Agency (IEA) published its latest estimation of the levelised costs of generating electricity (LCOE).
In every region in the world, nuclear power is computed to be the cheapest source of electricity, when the discount rate is 5%. The 10% discount rate just increases the costs of onshore wind electricity, while nuclear powered electricity still demands the lowest costs in North America and Asia Pacific regions.
This kind of analysis not new. Nuclear electricity always tops the electricity from renewable sources in terms of costs. When numbers are out, governments cannot ignore them.
How can renewable energy sources compete with non-renewable (and possibly dangerous) ones?
I want to find the answer!!!!!

Solar power market is half of wind power market

Last year, global solar power market ($30.7 billion) was less than half of world's wind power market ($63.5 billion).
