How to Make Your Home Smart and Energy Efficient
July 2, 2014 07:43 AM - Jessica Oaks, Triple Pundit
You may not realize it, but at this very moment, you’re probably wasting electricity. Don’t feel too bad though; the fact of the matter is, most people are using more electricity than they need. The home is filled with electronic devices, and keeping track of them all can be a real hassle. Most of us tend not to think about it. After all, what damage can possibly be done by leaving the lights on in a room or setting the thermostat a couple of degrees cooler? Well, more than you probably think. When it comes to electrical usage, one should think of the age-old economic theory, the Tragedy of the Commons. The principle is simple: Individuals acting rationally and in their own self-interest can actually act against the best interests of the group, by wasting a common resource needed by the collective whole. You may not believe that you’re using an exorbitant amount of electricity, but over time, this usage adds up. And this usage burdens the electrical grid and increases your spending. Thankfully, by being conscious of this fact, you can make changes that benefit your wallet, and the community as well.
Choosing the Right Path: How Air Travel Affects Climate Change
June 26, 2014 10:40 AM - Winfield Winter, ENN
It has been well documented that one negative of air travel — besides the food — is the emission of CO2 from jet engines. But what about contrails? Dr. Emma Irvine, Professor Keith Shine, and Professor Sir Brian Hoskins, at the Department of Meteorology at the University of Reading have linked contrails to global climate change in a study published in IOP Publishing’s journal Environmental Research Letters. According to their report, contrails may have a greater radiative forcing (the capacity for an agent to enact climate change via warming) than CO2.
Solar Power Meets Half of Germany's Energy Demand
June 26, 2014 10:00 AM - Andrew Burger, Triple Pundit
A core facet of Chancellor Merkel's historic "Energiewende" clean energy transition, Germany has led the world in driving adoption of solar energy technology and systems. Although it is now pulling back hard on incentives, the market momentum created by its precedent-setting solar energy feed-in tariff (FiT) persists.
Getting a better handle on CO2, NASA will help!
June 26, 2014 06:17 AM - Roger Greenway, ENN
From all the news about how anthropogenic emissions of CO2 are increasing tremendously (remember the hockey stick graph?) you would think that these emissions are causing all the atmospheric increases of CO2. And, our use of fossil fuels is increasing exponentially, with more than half of all fossil fuels ever used by humans being consumed in the last 20 years. However, in comparison with the amount of carbon that enters the atmosphere from natural sources, our fossil fuel emissions are modest. "Carbon dioxide generated by human activities amounts to only a few percent of the total yearly atmospheric uptake or loss of carbon dioxide from plant life and geochemical processes on land and in the ocean," said Gregg Marland, a professor in the Geology Department of Appalachian State University, Boone, North Carolina. "This may not seem like much, but humans have essentially tipped the balance."
Bio-fuel from Whisky distilling in Scotland
June 25, 2014 08:00 AM - ClickGreen staff, ClickGreen
Edinburgh-based biofuel company Celtic Renewables has signed an agreement with Europe’s foremost biotechnology pilot facility to undergo next-stage testing of its process to turn whisky by-products into biofuel that can power current vehicles. The partnership, which will allow the company to develop its technology at Bio Base Europe Pilot Plant (BBEPP) in Ghent, has been made possible by second round funding worth €1.5million, including more than €1million from the UK Government, to help meet its ambition of growing a new €125 million-a-year industry in the UK.
Coal mines to Solar PV in UK

Energy specialists Anesco is to undertake a major regeneration of a number of former colliery sites with the development of a 30MW solar portfolio. The ground-mounted solar installations will be operational for 25 years and, once completed, will generate enough low-carbon energy to provide powerfor around 10,000 homes, while saving up to 15 tonnes of carbon per year.
Update: the future of EV's in China
June 21, 2014 09:45 AM - Belfer Center, Harvard University
China has ambitious goals for developing and deploying electric vehicles (EV). The stated intention is to "leapfrog" the auto industries of other countries and seize the emerging EV market. Since 2009, policies have included generous subsidies for consumers in certain locations, as well as strong pressure on local governments to purchase EVs. Yet four years into the program, progress has fallen far short of the intended targets. China has only about 40,000 EVs on the road, of which roughly 80% are public fleet vehicles such as buses and sanitation vehicles. China’s EV industry faces the same challenges as companies in the West: a) high battery costs; b) inadequate range between charges; and c) no obvious infrastructure model for vehicle charging.
Wind power to reduce shipping CO2?
June 20, 2014 09:29 AM - Manchester University
Wind propulsion such as kites and Flettner rotors could offer a viable route to help cut CO2 emissions in the shipping sector, according to Dr Michael Traut, a Research Associate from The University of Manchester. Speaking at the 'Shipping in Changing Climates: provisioning the future' Conference in Liverpool today (Thursday), Dr Traut will present research that uses a new model to couple wind-power technologies with weather data to show how in theory, and with supporting incentives, wind energy could cut CO2 and fuel use by as much as 50% on smaller cargo vessels up to 5,000 dead weight tonnes. This would also have a knock-on impact of cutting sulphur and nitrogen oxide and dioxide emissions by reducing the total amount of fuel burnt.
Soccer Under The Sun
June 20, 2014 08:00 AM - Winfield Winter, ENN
The 2014 FIFA World Cup Brazil is underway and off to a bright start. For the first time in the tournament's history, matches will be held in stadiums powered by solar energy. Footballers from the 32 nations represented may curse the sun and the swelter it brings, but Yingli Solar, the world's largest solar panel manufacturer and a FIFA World Cup Sponsor, has captured an opportunity on the world's biggest stage. Yingli Solar estimates its solar panels to generate more than 1MW per year and clean electricity for 25 years or more. The iconic Estádio do Maracanã that witnessed Pelé's 1000th career goal and much of Brazil's rich footballing history is one of the two sites that received this modern upgrade. This Rio de Janeiro landmark that opened in 1950 now boasts 1,500 Yingli Solar panels with the capability to produce 550MWh of clean electricity per year.
Brazilian Courts order lower electromagnetic pollution
June 12, 2014 02:09 PM - Elza Boiteux
The Brazilian Judiciary determined to reduce the level of electromagnetic pollution generated by power lines to standard adopted by Swiss law (1.0 microtesla). Two associations of residents in São Paulo — the largest city of Brazil — proposed the action. The plaintiff has pleaded to not be exposed to electromagnetic fields incompatible with the human health. The electromagnetic fields generated by power lines that cross these areas is 10 times greater than the level determined by the court. The judgment of the Court of State of São Paulo (Tribunal de Justiça de São Paulo) has determined that the concessionaire of electric power reduces the electromagnetic field generated by power lines that pass through these neighborhoods.
