11 billion miles from Earth, "Grand Tour of the Solar System" comes to an end
December 14, 2011 02:25 PM - Click Green Staff, ClickGreen
In 1977, Jimmy Carter was sworn in as president, Elvis died, Virginia park ranger Roy Sullivan was hit by lightning a record seventh time, and two NASA space probes destined to turn planetary science on its head launched from Cape Canaveral. The identical spacecraft, Voyager 1 and Voyager 2, were launched in the summer and programmed to pass by Jupiter and Saturn on different paths. Voyager 2 went on to visit Uranus and Neptune, completing the "Grand Tour of the Solar System," perhaps the most exciting interplanetary mission ever flown. Now NASA has announced that Voyager 1 - about 11 billion miles from Earth - has now sailed to the edge of the solar system and is expected to punch its way into interstellar space in the coming months or years. Voyager 2 is not far behind, but on a different trajectory.
UK issues severe weather alert as experts warn of worst storm in decades
December 13, 2011 09:10 AM - ClickGreen staff, ClickGreen
Government officials have this afternoon issued a warning as one of the stormiest periods the UK has seen for several years is set to worsen. Weather experts warn the strength of an incoming low-pressure system can already be compared to the Great Storm of 1703. According to the advisory released by the Central Office of Information this afternoon, the end of the week in particular could see dramatic stormy conditions across England and Wales.
UK approach on renewable energy is deeply flawed, claims new report
December 12, 2011 07:48 AM - Click Green Staff, ClickGreen
The Government's roll-out strategy for sources of renewable energy are misguided, according to a highly critical report released today by the Adam Smith Institute and the Scientific Alliance. The UK’s plans for renewables are unrealistic, and these technologies cannot provide the secure energy supply the country needs, the report suggests and it claims present policies will lead to an energy crisis by the middle of this decade. The report states that wind and solar power do little to reduce carbon emissions, as they need large-scale back up generating capacity to compensate for their down times.
Measuring carbon emissions: How can business really be accurate?
December 9, 2011 12:22 PM - Click Green Staff, ClickGreen
The Department of Energy and Climate Change recently published the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme performance league tables which has ranked companies according to their carbon emissions. While the program is aimed at improving energy efficiency and cutting emissions in large public and private sector organizations, some believe there are alternative and more effective ways of doing this. Earlier this year, the US Department of Energy (DoE) issued recommendations for measuring and publishing energy efficiency in Power Usage Effectiveness (PUE) for all data centers with the aim of delivering a consistent and repeatable measurement strategy that allows data center operators to monitor and improve the energy efficiency of their facilities. The DoE has openly recognized how effective PUE is but the question remains as to which measurement should be used in the UK. Should we follow the US example of using PUE or stick to the controversial CRC scheme?
Weather experts warn of second huge storm to hit length and breadth of UK
December 9, 2011 09:30 AM - ClickGreen staff, ClickGreen
A second hurricane-strength storm is heading for the UK and this time the entire country looks set to suffer. Forecasters say the next severe storm is now brewing in the North Atlantic and will bring with it cold air, snow and sleet as well as hurricane-strength winds from Monday evening.
Wind turbines are supposed to like the wind!

Huge wind turbine erupts in flames as 165mph winds strike Scotland These amazing pictures show the moment a huge wind turbine erupted in flames after it was struck by hurricane-force winds in Scotland. Local photographer Stuart McMahon from Ardossan, North Ayrshire, snapped the fireball as it wrecked the turbine earlier this afternoon. Stuart told ClickGreen tonight the blades on the 30mw turbine had been braked and were not turning as the ferocious winds swept across Scotland. "It was clear that the turbine caught fire first and the flames spread to the covering of blades," he said. "There was debris still on fire being swept off in the wind and across the fields." "These are huge structures and to see one on fire was a spectacular sight." "The fire must have lasted for about 15 or 20 minutes until the fire brigade turned up to put out the fire." The Ardrossan wind farm was sold by Scottish and Southern Energy to Infinis last year for £54 million. It comprises of 15 turbines with the capacity to power about 29,500 homes.
Solar power can now be produced for less than $1 a watt, study finds
December 8, 2011 09:01 AM - ClickGreen staff, ClickGreen
Solar PV energy can now be produced for less than $1 a watt although the public is being kept in the dark about its true viability, according to a new study by Queen's University.
Three-quarters of English Channel sea birds contain toxic levels of plastic
December 5, 2011 08:35 AM - ClickGreen staff, ClickGreen
Data from studies monitoring the amount of consumer plastic eaten by sea birds suggest that levels in the North Sea are well above targets... and the figures are rising. For the most recent monitoring period, the target amount was exceeded in well over half the birds studied, with the English Channel being the worst affected region with 74% of birds over the threshold.
NASA data confirms pollution has nearly halved from US coal power plants
December 2, 2011 02:18 PM - ClickGreen staff, ClickGreen
A team of scientists have used the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite to confirm major reductions in the levels of a key air pollutant generated by coal power plants in the eastern United States. The pollutant, sulphur dioxide, contributes to the formation of acid rain and can cause serious health problems.
Green policies can halve CO2 emissions from energy sector, says OECD and IEA
December 1, 2011 04:08 PM - Click Green Staff, ClickGreen
Rising global energy demand and the need to drastically cut carbon dioxide (CO2) emissions require a transformation in the way nations produce, deliver and consume energy, according to a new joint report from the OECD and IEA. The Green Growth Studies: Energy report says governments need to increase energy efficiency and lower the carbon-intensity of the sector. As developed countries renew their energy infrastructure and developing countries build new power plants to meet growing energy demand, the time is right to make crucial choices for the future of the energy sector, the report says. With the energy sector responsible for the majority of CO2 emissions, green growth policies could halve worldwide energy-related emissions of CO2 by 2050 using a combination of existing and new technologies.
