Record-breaking summer for renewable power

Record-breaking summer for renewable power

Technology
Supplies of renewable energy, such as solar and wind power, in the UK have outstripped fossil fuels this summer.On 26 May, solar panels produced more than a quarter of all electricity needed in the country, with windy and bright conditions helping renewable energy generation to smash records.And for the first time on 7 June, wind, nuclear and solar were all generating more than gas and coal combined.The falling cost of wind and solar technology makes it increasingly attractive and energy firms have installed tens of thousands of solar panels in recent years.The home roof market has also boomed with an estimated 900,000 systems now online, despite generous government subsidies all but drying up in the last two years.Image:Wind and solar power are quickly growing in popularityDunsfold Aerodr...
Power firms alerted on hack attack scenarios

Power firms alerted on hack attack scenarios

Technology
Power firms around the world are being warned about how to spot if they are being targeted by hackers who shutdown parts of Ukraine's electricity grid.The warnings have emerged from analysis of the malware used in an attack in Ukraine in December.That left about 230,000 people without power for hours after substations were shut down via implanted malware.The move comes as researchers at Black Hat and Def Con reveal ways power firms are lax on security.Immediate risk"Power grid operators need to be aware that these styles of events are out there and they need to prepare for them," said Robert M Lee of Dragos Security during a talk at the Black Hat show which detailed its work to analyse the malware used in the Ukraine attack.Ukraine suffered two attacks on its network - one in March 2015 an...
Spending power in longest decline since 1970s

Spending power in longest decline since 1970s

Business
Household spending power is in its longest decline since the 1970s and the rate at which consumers are saving has fallen to a record low, official figures show.The Office for National Statistics said household disposable income, adjusted for inflation, fell by 1.4% in the first quarter of this year.It was the third quarter of decline in a row - the first such extended squeeze on households since the period up to the second quarter of 1977.It prompted a fall in the percentage of household income which is saved to 1.7%, the lowest savings ratio since records began more than 50 years ago.The figures will add to concerns about the squeeze caused by higher inflation - largely as a result of the slump in the pound after the Brexit vote.They come a day after Bank of England figures showed consume...
Questions raised over Battersea Power Station

Questions raised over Battersea Power Station

Technology
The cage that hoists you to the top of the north west chimney of Battersea Power station, 102 metres high, stops with a shudder.Clamber out and you see a wide and telling view. You're eye level with the three other famous chimneys; around you, the cavernous, hollow interior of the turbine hall and switch houses; below, three thousand builders on site, a hive of activity; and following the flow of Thames up to Vauxhall, a mess of crane-strewn sites, the biggest redevelopment project in Europe.I'm here to see the finishing touches put, by hand, to the chimney. One of the conditions for redeveloping the power station was keeping the power station.They were in bad shape, so they were laser scanned, demolished, then rebuilt - using the same technique as their original construction in the 1930s....
Liquified gas electrolytes power new lower-temperature battery

Liquified gas electrolytes power new lower-temperature battery

Science
June 16 (UPI) -- Scientists at the University of California, San Diego have developed new electrolytes capable of powering batteries at temperatures as low as negative 80 degrees Celsius.The technology could help make lithium ion batteries safer and more efficient, as well as boost the range of electric vehicles during cold winter months. The new batteries could also power vehicles and instruments operating in extreme cold, like space rovers, satellites and high-alitiude weather baloons.The electrolytes are composed of liquefied gas solvents. Many gases require extreme pressure to liquify. Gases that liquify at moderate pressures are less apt to freeze.To create their battery's electrolyte, researchers liquified fluoromethane gas. For the capacitor electrolyte, scientists liquified difluor...
