Dear All,

Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This blog tries to capture that reality – enjoy the read.

RENEWABLE ENERGY – GENERAL (Policies, Events, Reports, Financing, …)

The Silent Energy [R]evolution 20 Years in the Making – Since the late 1990s, wind and solar installations have grown faster than any other power technology across the world. But it’s still too early to claim the end of fossil-based power generation. – Full Article http://www.renewableenergyworld.com/rea/news/article/2011/08/the-silent-energy-revolution-20-years-in-the-making?cmpid=SolarNL-Tuesday-August30-2011

New Studies on Global Status and Trends in Renewable Energy:

Global investments in green energy up nearly a third to $211 billion in 2010. – For the first time, developing economies overtook developed ones in terms of “financial new investment” on utility-scale renewable energy projects. – Renewables investment (including large hydro) is clearly ahead of both gross and net investment in fossil fuel capacity. – China, developing countries are now biggest investors in large-scale renewables while Germany surges ahead on rooftop solar. – Positive trend in government research and development in renewables spotlighted—up over 120 per cent to well over $5 billion.

Read at least the executive summaries of these studies:

In case you want to dig even deeper into the status of RE I recommend the 1544 pager of IPCCs final release of its “Special Report on Renewable Energy Sources and Climate Change Mitigation”, which is available for download from: http://srren.ipcc-wg3.de/report Chapters which add significantly to the above studies are: 8, 9 and 10. I would recommend that you start your read with having a look at the summary for policy makers and the technical summary.

The INTERNATIONAL ENERGY OUTLOOK 2011 (from US Energy Information Administration) is out. In the IEO2011 Reference case, which does not incorporate prospective legislation or policies that might affect energy markets, world marketed energy consumption grows by 53 percent from 2008 to 2035 and that half of that growth will come from China and India. – Download here http://www.eia.gov/forecasts/ieo/

Women’s participation in energy projects – Women in communities across India are playing an increasingly important role in identifying energy needs, confronting projects they deem unsustainable, and contributing to alternatives in the context of India’s rapid expansion of the energy sector to drive economic growth. Furthermore, their participation is contributing to a gradual process of social change and women’s empowerment. – Full report. http://www.brettonwoodsproject.org/art-569025

  1. I’ve been a practicing solar energy professional for over 10 years: My bachelor’s was in EE, master’s degree in solar energy engineering and now work as a solar project developer and investor. I picked up this book at the PV America conference a couple of days ago – and read the whole PV grid-connected section towards the end of the book. I also read through the early “intro” chapters and the

    The book covers a huge, but highly relevant selection of topics. Bottoms up, if you’re building up from basics, it covers all the relevant basics in the early chapters, and technology-specific basics wherever relevant. e.g. the PV coverage of cell-basics, equivalent circuits and modeling, and adding up to modules and array performance, system sizing and economic analysis is very well done – you have enough knowledge after reading these chapters to do calculations, basic-to-advanced designs, and understand more detailed texts.

    As a reference, almost anyone would benefit from the more advanced and thorough discussions. e.g. in the discussion on DC, standalone PV systems, you can quickly go through key issues relating to PV module performance with specific types of loads, e.g. resistors, DC motors etc, and understand the impact of max power point trackers, and design issues. The author has thought through the text from the readers’ point of view: Every relevant angle was discussed and covered with clear text, plus wherever relevant, numerical calculation examples are given such that a reader can replicate in real-life situations.

    A complaint and a couple of warnings. My one gripe: Much of the industry data in the book is “old”, i.e. 2002-2003 vintage. I have access to more recent data, but an update to the book might be useful. Caution (who’s this book for): If you’re not an engineer by training, have no technical background, and don’t like numbers, this book will be of limited use to you – though far from useless. Also, if you’re an experienced engineer working in either solar or wind design, your main utility for this book will be as a reference, a quick overview of basics and less-used topics.

    All in all, I was waiting for a book like this for a while. I’m glad I bought this, despite a discounted (conference) price above $120, and look forward to using it as a reference for a long time.
