Electric cars could drive from London to Edinburgh on a single charge using a new battery technology being developed at Cambridge Univeristy, scientists have said.The lithium-air technology could be used to develop batteries that are a fifth of the cost and weight of current electric car batteries – enabling them to match the range of petrol and diesel cars.Although real-world usage remains “at least a decade away”, scientists say they have overcome a number of obstacles to develop a working laboratory prototype of the battery.
UK small and medium-sized (SMEs) businesses are wasting more than £82 million per year on their energy bills.That’s according to new analysis from the Energy Efficiency Financing (EEF) Scheme which stated the overspending is due to inefficient technology and old equipment.The EEF scheme is a joint initiative between the Carbon Trust and Siemens Financial Services.They studied businesses’ use of lighting, heating and hot water, cooling and ventilation and other areas of energy consumption.The report concluded “potential” energy savings of more than £414 million could be achieved per year if they invest in more energy efficient equipment.Richard Baker, Sales Manager, EEF scheme said: “Today’s tightened credit environment makes it increasingly difficult for SMEs to obtain affordable funding as traditional lenders have become more risk-adverse in their lending policy.“Consequently, many firms feel discouraged from investing in green technologies because of insufficient access to capital. However, with funding available from innovative schemes like EEF, where expected savings pay for the investment, organisations can now act on their green endeavour without having to worry about upfront capital.”
A factory that makes the traditional British dish of pie and mash has become the first factory in the world to be run entirely on power generated by potatoes.
Power is generated for the Cavaghan and Gray ready-meals plant in Carlisle, Cumbria, through a bio-refinery that converts leftover potatoes and peelings into electricity and steam.
The state-of-the-art green generator will produce 3,500 MWh a year, which is enough to supply power to 850 homes.
The potato-powered generator is also expected to produce 5,000 MWh a year in steam.
The potatoes used to create the power are taken from their own pie and mash food line, used to create ready-meals that are available in all major supermarkets.
New onshore windfarms are now the cheapest way for a power company to produce electricity in Britain, according to Bloomberg New Energy Finance (BNEF).Costs have dropped to $85 (£55) per megawatt hour (MWh) compared with the current costs of about $115 for constructing coal or gas-fired plants, its analysis found.The price of wind, which has fallen from $108 just 12 months ago, compares with nuclear which Bloomberg assesses at $190 – the latter up on a year ago as project delays are factored in to developments.
