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.

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.

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.

Prepare yourself for the green economy

The UN estimates that there could be millions of green jobs created as the industry grows in the next few years. They call for subsidies to speed up the creation of these green jobs, but also acknowledge that the market will shift in that generation anyway as the cost of gas and oil continues to rise.

Let's form a climate change brain trust

Former UK chief scientist Sir David King is calling for a concerted effort to combat climate change. Especially, as it's his area of expertise, scientific work on the scale of CERN to look for alternative energies and clean up technologies.

Sir David commented that global warming was more dangerous than terrorism whilst he was chief scientist, a comment that anyone with half a brain could see was logical and nowhere near as controversial as some made it out to be. In fact, as it affects the poorer nations more, fuelling feelings of injustice and eventually leading to overcrowding and all the problems that entails, it could be said that climate change is a major factor in increasing terrorism. Fight the cause, not the symptoms.

Obama on energy policy

One of 14 questions about science issues answered by the presidential candidate.

3. Energy. Many policymakers and scientists say energy security and sustainability are major problems facing the United States this century. What policies would you support to meet demand for energy while ensuring an economically and environmentally sustainable future?

America's challenges in providing secure, affordable energy while addressing climate change mean that we must make much more efficient use of energy and begin to rely on new energy sources that eliminate or greatly reduce greenhouse gas emissions. My programs focus both on a greatly expanded program of federally funded energy research and development and on policies designed to speed the adoption of innovative energy technologies and stimulate private innovation.

First, I have proposed programs that, taken together, will increase federal investment in the clean energy research, development, and deployment to $150 billion over ten years. This research will cover:

• Basic research to develop alternative fuels and chemicals;

• Equipment and designs that can greatly reduce energy use in residential and commercial buildings – both new and existing;

• New vehicle technologies capable of significantly reducing our oil consumption;

• Advanced energy storage and transmission that would greatly help the economics of new electric-generating technologies and plug-in hybrids;

• Technologies for capturing and sequestering greenhouse gases produced by coal plants; and

• A new generation of nuclear electric technologies that address cost, safety, waste disposal, and proliferation risks.

I will also work closely with utilities to introduce a digital smart grid that can optimize the overall efficiency of the nation's electric utility system, by managing demand and making effective use of renewable energy and energy storage.

Second, it is essential that we create a strong, predictable market for energy innovations with concrete goals that speed introduction of innovative products and provide a strong incentive for private R&D investment in energy technologies. These concrete goals include:

• Increasing new building efficiency by 50 percent and existing building efficiency by 25 percent over the next decade, and taking other steps that will reduce the energy intensity of our economy 50 percent by 2030;

• Increasing fuel economy standards 4 percent per year and providing loan guarantees for domestic auto plants and parts manufacturers to build new fuel- efficient cars domestically;

• Extending the Production Tax Credit for five years and creating a federal Renewable Portfolio Standard that will require that 10 percent of American electricity be derived from renewable sources by 2012, and 25 percent by 2025; and

• Ensuring that regulations and incentives in all federal agencies support the national energy and environmental goals in ways that encourage innovation and ingenuity.

I will also encourage communities around the nation to design and build sustainable communities that cut energy use with walkable community designs and expanded investment in mass transit.

Solar planes can stay in the air for days

The Zephyr is a prototype solar powered unmanned aerial vehicle which recently unofficially broke the world endurance record for unmanned flight. Obviously, it's being developed for military use, but the company behind it are predicting civilian implementations. It'll be a long time before the equipment is able to carry large payloads around the world, but high flying drones could be used for pollution monitoring and other forms of information gathering.

Formula Zero- the hydrogen fuel cell racing series

Motor racing is often a testing ground for features that eventually make their way into everyday vehicles. So a zero emission karting series bodes well. The karts run on electric motors powered by fuel cells and compete to see not which is fastest but also which is most efficient. A British team placed third overall in a recent race, behind Dutch and Spanish entries.

Pimp my Prius

A trio of Swedish customisers have spent over $180,000 blinging up a Toyota Prius. Of course, all those mods add weight and energy requirements, so it'll certainly be a lot less efficient than a standard version.

Plus, most of what they've done just serves to make a dull car ugly.

It's about time somebody stepped up to make Prii more attractive, but this certainly isn't the way.

I prefer the Lib Dem's green energy policy

I'm with Nick Clegg when he talks about how wrong-headed the government is in its championing of nuclear power.

"The thing that I think has gone wrong in this debate is that the government has spooked everyone into thinking that we need nuclear by saying there's going to be a terrible energy gap - the lights are going to go out in the middle of the next decade.

"There's actually no evidence that's the case at all. They've raised the wrong problem in order to push the wrong solution.

"The real problem is that our energy mix is not green enough and we're over dependent on oil and gas from parts of the world that aren't very reliable."

This continued support of nuclear is typical of government. No matter what they may say, they don't want to devolve too much power to their electorate. Everything has to be solved by big, centralised projects that the general population has no say over and which will ultimately come in late and fail to deliver everything they promise. The answer isn't Uranium but a wide spread of projects at the local, and even household, level that will get the public enthused and involved in problems that effect us all.

Greenbird- wind powered record attempt

Wind cars are the future, according to the team behind Greenbird, a land yacht which is due to attempt to break the world record for a wind powered land vehicle. Greenbird uses a rigid wing rather than the traditional sail in its effort to exceed 116mph.

I can see wind vehicles as a a viable transport method for the great expanses of Australia, Africa and even the US midwest. Rigid sails and some sort of computer control would cut down on the need for tacking, but there'd still need to be a bit of room given to the vehicles, so they couldn't cope with crowded roads. Throw in some photovoltaic panelling and combined dynamos/motors in the wheels for electric drive at either end of the journey and it might work.

Wouldn't you like a solar powered car?

Well, you can have one, for less than twelve pounds. Admittedly, it'll fit in your hand and not be much use for the commute. But you could build a little track and let it race around when the sun shines.

Tidal power gets plugged into the grid

I missed this at the time- it's a couple of weeks old- but Britain's first tidal power generator has been plugged into the national grid. The SeaGen device is in Strangford Lough in Northern Ireland and generates 150 kilowatts- which should rise to 300 kilowatts by the end of the summer. The company behind the installation intends to set up a tidal power farm off Anglesey by 2011.

Kite Power

Wind turbines are okay, but they're close to the ground, whee wind speeds are relatively low and there can be turbulence to cut their efficiency. If you want to make the most of wind power you really need to go up to 800 metres with a kite.
