+ - Reducing UK housing CO2 emissions by 80% by 2050->

Submitted by
DamonHD
DamonHD writes "The Low-carbon Strategy from the Environmental Change Institute http://www.eci.ox.ac.uk/ at Oxford University identifies the policies needed to deliver an 80% cut in carbon emissions from UK homes by 2050. These cuts are achievable but will require a quantum leap in commitment from Government and a radical new approach.

The policies have been designed not only to dramatically reduce carbon emissions, but also to be delivered equitably. The poorest households will be prioritised for assistance and fuel poverty will be wiped out. The scientific consensus is that for the UK to play its part in helping the world avoid a rise of more than 2C, we must reduce our carbon emissions by 80 per cent by 2050. The household sector represents 27% of our total emissions and achieving deep cuts here is an imperative.

The low-carbon revolution starts at home.



Their previous work at http://www.40percent.org.uk/ from two years ago is also very interesting and thorough.

I'm amazed to find that with some simple measures at my home/office my family seems to have hit something like the 2014 targets already..."

+ - Dead Milk Tanker for Zero-Carbon London Home->

Submitted by
DamonHD
DamonHD writes "Is it possible for a small urban (London, UK) home to be powered entirely by locally-collected Renewable Energy, both for electricity and for heating?

An important issue is that there is only ~20% of the solar energy per day in winter compared to summer, so one way to make the whole project more likely to work is to store energy from the summertime to the winter.

This article looks at storing enough heat energy out of the ~26GJ used by one house per year for water and space heating to last the winter, 'charged' by solar thermal panels year-round.

And yes somewhere between 1 and 3 dead water-filled milk tankers buried in the the ground could hold the required energy!"

DamonHD writes "Timed for when the clocks go back, Sainsbury's said it wanted to encourage people to save electricity during the dark months ahead.

To claim their bulb, customers will have to take an energy-saving pledge that urges people to recycle bags and switch to showers from baths.

Sainsbury's typically sells an average of one million green lightbulbs a year."

+ - Asia Pacific Cable Network 2 break(s) off Taiwan

Submitted by
DamonHD
DamonHD writes "It seems that the earthquake off Taiwan on Boxing Day caused the Asia Pacific Cable Network 2 submarine cable fault between Shantou, China and Tanshui, Taiwan and between Lantau, Hong Kong and Chongming, China.

Connectivity within AsiaPac can be patchy at the best of times: this APCN2 break has made it noticeably worse and disrupted traffic to and from the US and Europe too..."

+ - What will be the new clockspeed ceiling at 45nm

Submitted by
DamonHD
DamonHD writes "http://www.reghardware.co.uk/2006/11/30/intel_45nm _crossover_coming_2008/

It looked like 3GHz to 4GHz has been a practical ceiling for CPU clocks for mainstream microprocessors with current fabs.

What kind of practical increase can we expect from a move to 45nm without blowing the thermal envelope and toasting our laptops and co-lo server farms? 2x?
