Britain leads the world in offshore wind power

With the latest batch of offshore wind turbines to come on line Britain has overtaken Denmark to become the world leader for offshore wind. However, we lag behind Europe in overall renewable energy generation and most of our turbines are built abroad.

Towards more efficient solar power

P Z Myers reports on research that could lead to near 100% efficient photovoltaic cells. It's still at an early stage and very small scale, but it sounds promising.

How to talk to a climate skeptic

I think I've linked to this useful collection of counter arguments to standard climate change denial before. But i find myself dropping links from it into occasional comments on some blogs that still use the tired old lines, so I thought I'd highlight it again.

British Waterways gets into the energy business

British Waterways is looking at ways to install windmills and hydroelectric generators along the banks of the 2,200 miles of rivers and canals it oversees.

Make way for the organic battery

Laccase, an enzyme produced by certain woodland fungi, has been shown to be a potential replacement for catalysts such as platinum in batteries and fuel cells. Deployment is a long way away, but if it happens it could see an end to energy intensive mining operations. Also interesting to note, Laccase breaks down lignin, one of the important steps in preparing cellulose materials for fermentation. So it could have an interim use in the production of ethanol from plant waste.

The Journey to Forever

Journey to Forever is a pioneering expedition by a small, mobile NGO (Non-Government Organization) involved in environment and rural development work, starting from Hong Kong and travelling 40,000 kilometres through 26 countries in Asia and Africa to Cape Town, South Africa.

Our route will take us away from the cities and populated districts to remote and inaccessible areas (usually also the least developed and poorest areas), where we'll be studying and reporting on environmental conditions and working for local NGOs on rural development projects in local communities.

The focus will be on trees, soil and water, sustainable farming, sustainable technology, and family nutrition.

The aim is to help people fight poverty and hunger, and to help sustain the environment we all must share.

The solar still information was found in The Journey to Forever's online library, which I shall have to trawl through for other useful snippets.

Wanna become a solar powered good ole boy?

How to build a solar still to distill alcohol. This is a chapter from a book all about home production of ethanol to run your car, but I'm sure the Dukes would find a way to make moonshine with it. Obviously it works better the more sunshine you get, but I think it would work almost as well with winter sun as with summer, albeit for shorter periods. The active solar still described could have its pump powered by solar cells and theoretically run faster when there's more sunlight, solving the regulation problems.

I'm against the production of ethanol as it's currently envisioned by governments and corporations, because it's taking away chunks of food producing land. The mash for the first brew should come from sugar loaded waste, not from perfectly good food products. On a domestic level would it be possible to make, say, an apple peel (and other compostables) brew that would taste vile but be a good basis for distillation?

Update Onfurther investigation I've found that the book has chapters on fermenting various base materials including starchy sources such as potatoes and cellulose materials including cor stalks and paper.

Hulme has a new eco school

The Rolls Crescent Community Primary School in Hulme has had a £5million revamp to incorporate energy and water saving technologies. All new public buildings should be required to be net zero carbon, or better, before they're given the go ahead. It sounds like a lot to ask, but in the long run it'll save money and set a good example.

The Queen has bought a big windmill

The Queen has invested in what is reportedly the largest wind turbine in the world, to be installed off the North East coast of England. She has previously had a water turbine installed in a wier near one of her castles and I believe the royal households are all going over to energy saving bulbs. All in all a good example to set to we commoners.
