An American researcher from ABC News has found that up to 80% of jobs in the US windpower sector are going overseas, particularly to China. Meanwhile, a story in the Los Angeles reports that the US wind energy industry is in decline:
"wind installations drop 71% in the first half and the forecast past 2010 looks dreary," the Los Angeles Times reports:

-------
"The U.S. wind industry is in distress," a top renewable energy advocate said Tuesday, and the situation appears as though it could get worse.

Denise Bode, chief executive of the American Wind Energy Assn., said that without a national renewable energy standard, investment and interest in wind projects past 2010 would be headed for a free fall.

Despite more than 5.5 gigawatts under construction, the…

Interview with Michael Ruppert on Peak Oil and Collapse

Source: Youtube videohttp://www.youtube.com/watch?v=b4gr6T_FHPI
Michael Ruppert interviewed by Chelsea Green and filmed for a Youtube video. Author of the From The Wilderness newsletter, Ruppert had become aware of Peak Oil by 2001 and predicted the 2008 economic collapse. Ruppert believes the first stage of the recession occurred when the oil price reached $47 per barrel and that there was no going back. Peak oil awareness really originates from the calculations of Hubbert from 1947 who predicted the pattern of oil exploration would follow a bell curve and would therefore reach a 'peak', hence the term 'peak oil'. When Hubbert predicted that US oil would peak in the 1970's, he was castigated for it, however as history showed, his prediction was correct. Ruppert believes that long before the Bush administration, the US government was aware of the approach of Peak Oil. The From The Wilderness website apparently contains declassified CIA documents showing that the CIA…

The UK company Narec are developing an offshore wind test site in the North Sea. It basically consists of up to 20 'pods' which may be used by tenants to test their prototype or pre-production wind turbines and foundations. The project employs Natural Power's ZephIR lidar at an onshore site to acquire data concerning wind characteristics across the site.

UK Climate Change Plan to hit poorest harder according to CSE

A recent study by the Centre for Sustainable Energy and the Association for the Conservation of Energy (ACE) has found that the impacts of the government's Low Carbon Transition Plan will hit poorer households harder in real terms.
The study pursued four main lines of enquiry:
What needs to be done to UK housing, in terms of sustainable energy deployment, in order to meet the target of 15% reduction by 2020.The proportion of this target to be met by renewable heat, renewable power and energy conservation.The range and size of technology required.The cost of meeting these targets and how these costs are recovered through domestic energy bills, income tax or a financial transaction tax.The study found that if the costs are recovered through domestic energy bills, the average household energy expenditure in 2020 will increase by £103 (assuming an existing figure in 2020 of £1,154) representing a rise of 8.5%. …

Renewable energy project for the Somerset levels

A new sustainable energy project has just started on the Somerset Levels, the intention being to help communities on the Levels to install their own small-scale renewable energy facilities. The Levels and Moors Energy Project will run in three phases:
Stage 1 involves publicity and calling for expressions of interest from the local community. This is the position the project has reached at the moment. A short list of viable projects will then be compiled. Stage 2 involves workshops and feasibility studies of accepted schemes. Grounds for acceptance include financial and technical viability, likelihood of receiving planning permission and broad acceptance by the local community.Stage 3 involves selection of the best 10 to 15 schemes which will then be given more detailed support to ensure financial and technical viability plus support for acquiring equipment , action planning and community engagement.The …

US Navy completes successful trial of biofuel-powered gunboat

Forced to adapt to the rising price of oil, the US Navy has successfully tested a gunboat which runs on algae-based fuel. Essentially the fuel is a 50-50 mix of algae and diesel and the navy plants to run half of the fleet on a mixture of biofuel and nuclear power by 2020. Rear Admiral Cullom, director of the US Navy's sustainability division stated that this was more to do with maintaining combat capability while avoiding being held hostage by restrictions on conventional fuel sources than it was to do with climate change.

Chicken Poo lights up Gloucestershire Town

http://www.guardian.co.uk/environment/2010/oct/28/chicken-poo-lights-town

A new plant in Cirencester will shortly be using chicken poo to supply energy to homes in the town. The biogas facility, a Combined Heat and Power (CHP) plant is estimated to be able to power around 350 homes and will begin operations in November. Essentially the plant works by capturing methane from decomposing agricultural waste. This is then burned in a generator to produce renewable electricity and heat. This is not the first such plant to operate in the UK as recently Centrica opened one near Didcot which uses human waste to supply energy.

Oxfam climate poster campaign cleared of being misleading by ASA

The Advertising Standards Authority have received four complaints about Oxfam's new poster campaign which has been designed to highlight the fact that climate change is happening right now and that people are dying directly because of it.
The ASA dismissed the complaints stating that Oxfam's message was not misleading. The bright pink poster reads "You're right. People dying thanks to climate change is a long way off. About 5000 miles give or take".

Images of London following climate change described as 'lazy' by refugee groups

The Museum of London recently staged a photomontage exhibition showing images of London following the impact of climate change. Some of them rely on photoshopped images of refugees and squatter camps and this has led to refugee charities denouncing the exhibition as 'cheapening' and 'stereotyping' refugees.

Licences for Oil and Gas Exploration cut back to protect Wildlife

Source: BBC News Online http://www.bbc.co.uk/news/uk-scotland-11635921
Licences for oil and gas exploration in UK waters were announced on Wednesday, including 22 licences for deepwater oil drilling opposed by environmental campaigners. These deepwater licences were granted across 64 sea blocks to the north and west of the Shetland Isles. However, the total number of licences granted has been cut by more than a quarter to 144. Other licences, due to be granted for areas such as the Thames Estuary, Liverpool bay and the north sea off the coast of Norfolk, have been withheld whilst tests are carried out by the Department of Energy and Climate Change (DECC) to establish potential impacts on wildlife.

Aberdeen-based oil company Petrofac has been awarded a £500m contract to develop a gas processing plant on Shetland. The scheme is being led by French company Total and is thought to promise hundreds of jobs whe…

News from Renewable Energy Focus

Here is an interesting story featured on Renewable Energy Focus, a very interesting an informative renewable energy website which is well worth a visit (see link).

http://www.renewableenergyfocus.com/view/13459/potential-for-deepwater-floating-offshore-wind-turbines/
According to the Energy Technologies Institute (ETI) offshore wind turbines could be sited in deep water off the British coast using floating foundations. These would be floating, tension-legged platforms located in areas of depth 70-300m. A feasibility study looking into this project was carried out by a consortium consisting of Blue H, BAE Systems, the Centre for the Environment, Fisheries and Aquaculture (CEFAS), EDF, Romax Technology Ltd, SLP Energy and PAFA Consulting Engineers.
ETI CEO Dr David Clarke stated that although there is a view that the cost of foundations increases with the depth of water, the wind speeds are significantly stronger and more consistent thereby resulting in a higher and more reliable energy ou…

What are the problems of relying on renewable technology? (Part 1)

This is the first part of a two-part article dealing with renewable technology and asking how efficient it is and whether it can be relied upon to replace fossil fuels on its own. At the present time, this looks dubious. The first part of this article looks at solar power. Both this and the article that follows it relies upon the Power Density Primer articles written by Manitoba University Professor Vaclav Smil as a stimulus for discussion.

Deepwater, Black Horizon: Deep offshore drilling and the coming energy crisis

The title of my second piece for Ask The Experts said it all really. Deep offshore drilling is another sign of an industry beginning to run out of options. If oil companies are willing to risk such dangers, both to the environment and to their reputations, they must be fairly keen to find new sources of oil resources as soon as they can. What does that say about how much oil we have left?
