Energy efficient bulbs to save the world

Well, not quite, but a review has estimated that a global switch to efficient lighting systems would cut the world's electricity bill by up to 10%.

"Lighting is a major source of electricity consumption," said Paul Waide, a senior policy analyst with the IEA and one of the report's authors.

"19% of global electricity generation is taken for lighting - that's more than is produced by hydro or nuclear stations, and about the same that's produced from natural gas," he told the BBC News website.

Biodiesel from Algae

Biodiesel and ethanol could be vital parts of the switch from oil dependency, but some of the current means of producing them are too energy intensive and damaging in their own right. PetroSun Drilling Inc. has created a subsidiary- Algae BioFuels Inc.- to research and develop algae cultivation as an energy source in the production of biodiesel. Studies have demonstrated that algae is capable of producing 30 times more oil per acre than the crops currently grown for biofuel production and the resulting fuel is low sulphur, non-toxic and biodegradable.

If they can find a way to break down waste products to provide nutrients, that would be even better.

Greenphase

As it seems the planning laws will change to make it as easy to mount a windmill on your house as a satellite dish, I thought I'd have a look around for suitable resources.

I didn't need to go far. Greenphase has a page listing suppliers of domestic wind turbines. In fact they have information about everything Green. They are now bookmarked and I'm on their mailing list.

MPs' green press releases

Only the one this week-

ENOUGH ENERGY TO POWER HAMPSHIRE TEN TIMES OVER SAYS WHITEHEAD

Alan Whitehead, MP for Southampton Test, said that offshore wind energy would produce enough energy to power Hampshire ten times over.

Speaking in an adjournment debate on Friday, Dr Whitehead argued the case for an extension of the use of wind energy as not only a non-carbon emitting source but a source that can contribute a substantial amount of power to the energy mix – the question is how we move to maximise this contribution by making it a viable option.

The Energy Act of 2004 allowed for a three phase roll out of off wind energy. So far only the first two phases have seen any development: wind farms in inshore waters close to the coast, and larger wind farms slightly further out to sea such as the Wash, Morecombe Bay and the Thames estuary. Dr Whitehead is therefore keen to see the next and third phase rolled out which would allow for the wind farms to be built in deeper and further waters, essentially up to the boundaries of the energy allocation zone for gas and oil.

Tony Blair's plan to destroy democracy whilst doing nothing for the environment

Senior sources say Tony Blair wants to send a clear signal that the government will make it easier for firms to build new power stations by shortening and limiting the number of public inquiries when they are built.

The proposals are designed to cut costs and make it harder for objectors to cause delays.

The sooner Tony Blair goes, the better. The Ministers are also likely to discuss "sweeteners", in other words ways to make the taxpayer pay for the profits of an industry that is no longer financially viable.

Planning permission to be waived for micro-generation

The Government is planning to streamline planning guidelines so that householders no longer need planning permission to install renewable energy technologies on their homes. The announcement of the planned change should, according to the Observer, be announced within ten days.

Many local authorities insist householders apply for planning consent. 'It is patently absurd that you should be able to put a satellite dish on your house but have to wrestle with the planning process for small-scale micro-generation, which is no more obtrusive and can have a real impact on tackling climate change,' Yvette Cooper, the planning minister, told The Observer

'We want much more micro-generation to be treated as permitted development. We are reviewing the impact of a wide range of technologies so we can take account of things such as the impact on neighbours or listed buildings before consulting on details later this year.'

It sounds like a good idea. Obviously the NIMBYs are all over it, unable to see the beauty in a windmill and fearing that unobtrusive flat solar panels will somehow blight their landscapes. Neighbours of David Cameron have deployed the old nonsense that his plans to erect a windmill will reduce the values of their homes. Maybe if they mocked his attempts to greenwash his way to credibility I'd have more sympathy for them.

Build your own solar thermal panel

Solar heating is a more efficient way to utilise the sun's power than photovoltaics, but somewhat more limited in applications. It is also much cheaper. In fact the team at The Seitch built a solar thermal panel for $5. They used the heat dispersal tubing from the back of a fridge (which had been purged of CFCs at the local dump) mounted behind a sheet of glass.

If you watyched It's Not Easy Being Green (we finally caught it on DVD-RWs from my parents) you might have seen the clever heat trap built into the Strawbridge's greenhouse. Perhaps a solar thermal panel such as this could make a near tropical greenhouse for exotic gardening.

4X4 drivers more likely to be idiots

A study by Imperial College has shown that drivers of Chelsea tractors are four times more likely to use mobile phones on the move and less likely to wear their seatbelts. So they're not just bad for the environment, they're a danger to everyone else on the road.

The solar car park

Invisible Heating Systems plan to install a Road Energy System, which uses heat absorbed by tarmac to warm water, in their car park. owever, this being Britain, torrential rain has meant the Midsummer Day start date has had to be put back.

It sould be a requirement that systems like this are included in any new road building. It might not work so well on urban roads, with all the utility pipes are running underneath them, but A roads and motorways should be viable.

The WI vs packaging

The National Federation of Womens Institutes has announced a plan to boycott supermarkets that don't cut down on unnecessary packaging.

The federation has identified ten fruit and vegetables as examples of produce it believes to be wrapped in unnecessary packaging.

This includes shrink-wrapped coconuts and peppers sold by Morrisons, and turnips, broccoli and cucumber with similar packaging at stores such as Tesco and M&S.

It criticises stores which sell bananas and spring onions in plastic bags and says it is ridiculous to put courgettes, parsnips and baking potatoes into trays before wrapping them in plastic. The federation's chairman Fay Mansell said: 'Our members are very disappointed to see this sort of packaging. They want potatoes and other produce as it is meant to be.

Electric Cruising

The Guardian on the electric car in Britain. Plug in hybrids and fully electric cars would be a great answer for towns, but the lack of off road parking where they can be charged is holding them back.

I've seen illuminated road signs and various other roadside devices that are solar and/ or wind powered. How hard would it be to create parking meters which were actually charging points, with solar panels on the top, batteries stored in the ground under them and a trickle feed from the mains for winter and overcast days? Electric car owners could pay a minimal amount to charge or be given pass keys, non-electric drivers would pay normal rates or be barred from them altogether. Another possibility would be placing windmills atop multi storey car parks and reserving a few spaces on the top level for replenishing electric vehicles.

MPs' Green press releases

NUCLEAR DECISION TOO IMPORTANT – DEBATE IS ESSENTIAL

Following Tony Blair’s statement in Prime Minister’s questions on the 14th of June, that the new generation of nuclear power plants will produce 1/10th of the waste of previous plants, David Heath has questioned the veracity of his information in Business Questions where he called for a debate on the issue.

Local MP David Heath cited the Independent Committee on Radioactive Waste Management, which has stated that a new generation of plants would lead to an increase in high level toxic waste of 400%.

IT’S HIP TO BE ENERGY EFFICIENT SAYS WHITEHEAD

Alan Whitehead, MP for Southampton Test, says HIPs (Home Information Packs) will put energy efficiency of homes top of the home buying agenda.

HIPs will come into place from 1st June 2007 and every home owner will need to prepare a HIP before putting their home up for sale. The Packs will include searches, a Home Condition Report (compiled by an independent Home Inspector) and terms of sale. An energy efficiency rating similar to fridge ratings will be included in the Home Condition Report, to tell people the running costs and carbon emissions from the home as well as identifying measures which could improve their energy rating.

This means that the energy efficiency of your new home will be there for you to see in black and white and will undoubtedly have an affect on both the price of your home and its attractiveness to potential buyers.

Utopia in the Highlands

Robotics lecturer Dylan Evans has a bleak view of the future. He believes civilisation will collapse within the next 35 years. To pre-empt the apocalypse he has sold all his possessions and is going to set up a community, Utopia, in the Scottish Highlands.

I agree that we're heading for major problems, but I'm not as pessimistic as Mr. Evans. It's entirely possible that our current systems will stop working, but action now could mitigate against the worst possible outcomes.

Industry's £500million of wasted energy

A study for the Carbon Trust says that UK businesses will waste more than £500m worth of energy over the summer months. Businesses could cut their energy bills by as much as 15% if they were more careful about energy usage.

Last summer I was working in a hospital. It wasn't the best office for natural light, but when there was no-one else there and the sun was good enough I'd turn off a bank of lights. Sooner or later one of the bosses, who worked in another office, would come along, turn the lights on again and tell me off for saving energy (okay, not for saving energy, in fact they never actually explained why it was so bad I was turning off lights that weren't in use).

Is the Green movement racist?

As a white, middle class (lapsed) man, it's not something I've thought about before, but representatives of ethnic minorities believe the environment debate isn't including them. That respect for the environment is at the heart of the Sikh, Hindu and Rastafarian religions is ignored, they say. The concerns are being raised at a London Sustainability Week conference.

Co-op Green Q&A

I recently ended a nine month contract in the CIS Tower in Manchester. One of the ten top Green projects of 2005 was the re-cladding of its service tower with solar panels. I thought it would be worth finding out a bit more about the Cooperative group's Environmental policies, sop I sent them a few questions. They were answered by Liz Thompson, an Environment Adviser at the company.

How much electricity will the solar tower generate?

The solar tower will generate 181MWh of electricity each year. This will result in a CO2 saving of 78 tonnes each year.

What percentage of the buildings total consumption is this?

The electricity generated will be enough to light six floors of the 25-storey high building or is equivalent to the annual electricity consumption of 55 average UK homes.

How long will it take for the solar panels to pay for themselves?

When the Tower was built in the early sixties, it was a pioneering and experimental building, and was, at the time, the tallest commercial building in the UK, leading to it becoming Grade 2 listed. However, while many aspects of the design were a success, the choice of millions of one-inch mosaic tiles to clad the windowless service tower was not. While the project will generate renewable electricity, its primary motivation was to tackle health and safety concerns. The mosaic tiles have been falling off since the building was built, and despite on-going re-fixing, over time it became clear that this was an increasing risk to the health of nearby pedestrians and was risking serious long-term damage to the building's structure. Various re-cladding solutions were explored, all of which cost many millions of pounds. The Tower's listed status meant that any solution which altered its external appearance would need robust justification. Given the significant expenditure already needed for repair and the ethics and sustainability stance of Co-operative Financial Services (see www.cfs.co.uk/sustainability2004), it made sense for us to look at novel construction materials that promote sustainable development. Due to the provision of grants, this sustainable construction project is cost neutral when compared to other repair solutions.

What other microgeneration schemes does the CFS have planned or completed?

CFS has placed 19 micro-wind turbines on the roof of its Portland Street office in Manchester, making it the largest commercial application of micro-wind turbines in the UK. It is estimated that the wind turbines will produce 44MWh of renewable electricity and save 19 tonnes of CO2 each year. The micro-wind turbines became operational in May 2006.

Are the schemes to generate power on or near sites linked with energy saving initiatives (eg. replacing all filament bulbs with compact fluorescent lights, making better use of natural lighting)?

We do look at lighting and energy management programmes across the organisation.

Are there any other environmental initiatives being taken by the CFS?

Yes there are numerous initiatives - please see www.cfs.co.uk/sustainability2004 then refer to the section on ecological sustainability.

What is the company doing to encourage green behaviour in its customers?

Again, numerous initiatives - we offer 'green banking/insurance products' such as our mortgages and CIS insurance product for car loans, our Customers Who Cares campaign - this year is all about Combatting Climate Change. More details can be found in the 2004 Sustainability Report.

The African Humid Period and its lessons on Global Warming

Between 8,000 to 5,500 years ago the Earth was as warm as it is now, and the Sahara was a rainforest. Much of this was down to the Earth's tilt, or precession, the stronger sun on the greenery driving water further inland to keep even the heart of the area moist. Over the course of a century the Sahara's ecosystem collapsed as the precession continued and changed sunlight levels and localised browning reduced the amount of moisture to be transferred. Now the dust that used to be the bed of lake Megachad is picked up by the wind and carried across the Atlantic to fertilise the Amazon.

It's possible that global warming could see a return of heavy rains to the Sahara and a regreening of the arid zone. However this isn't such good news on the global scale as other areas, notably prosperous zones like the west of North America, suffer ever longer drought periods. The Amazon could collapse as the Sahara blooms.

The Independent article linked to is an edited extract from The Last Generation by Fred Pearce.

Tycoons against CO2

A dozen representatives of big business will today meet with Tony Blair to urge him to take stronger action against CO2 emmissions and do more to combat climate change. They, rightly, argue that forcing British industries to innovate will make them more efficient and give them a lead in what is going to be a major field.

Other industry groups, of course, have argued the opposite. I think it's time to close down the CBI (Confederation of British Industry) because they obviously don't have their members' best interests at heart. Every time I hear Sir Digby Jones on Today he sounds like an arrogant buffoon. I know I wouldn't want him speaking for me.
