80% of Europeans want a low carbon economy to help tackle climate change
March 3, 2014 08:17 AM - ClickGreen Staff, ClickGreen

Four out of five people in the European Union recognize that fighting climate change and using energy more efficiently can boost the economy and employment, according to a special Eurobarometer opinion poll on climate change published today.

Electric cars and the grid
February 28, 2014 07:31 AM - Click Green Staff, ClickGreen

Car owners in the United States last year bought more than 96,000 plug-in electric cars, a year-on-year increase of 84 percent from 2012. However, this growing fleet will put a lot of new strain on the nation’s aging electrical distribution systems, like transformers and underground cables, especially at times of peak demand — in the evening when people come home from work.

Potential new source of renewable energy found in humidity
February 27, 2014 12:15 PM - Kristin Kusek, Harvard University

A new type of electrical generator uses bacterial spores to harness the untapped power of evaporating water, according to research conducted at the Wyss Institute of Biologically Inspired Engineering at Harvard University. Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors.

Passing the baton in oil spill research on the Gulf Coast
February 26, 2014 09:30 AM - Woods Hole Oceanographic Institution Media Relations Office

As part of on-going research nearly four years after the Deepwater Horizon oil spill, scientists from the Woods Hole Oceanographic Institution (WHOI) will team up with a group of high school students in Florida to collect remnants of oil from Gulf Coast beaches this week. Marine chemist Chris Reddy studies how the many compounds that compose petroleum hydrocarbon, or oil, behave and change over time after an oil spill. He and his researchers have collected and analyzed about 1,000 oil samples from the Gulf Coast since the Deepwater Horizon oil spill.

Off-shore Wind Turbines May Weaken Hurricanes

As one of nature's most destructive forces, hurricanes are unstoppable storms that can cause total devastation for coastal communities. While Mother Nature is unpredictable and uncontrollable, there are researchers and scientists who think hurricanes can be weakened or even stopped. One idea: wind turbines. New research by the University of Delaware and Stanford University shows that an army of offshore wind turbines could reduce hurricanes' wind speeds, wave heights and flood-causing storm surge.

Limitations of climate engineering
February 25, 2014 12:59 PM - Jan Steffen, GEOMAR Helmholtz Centre for Ocean Research Kiel

Despite international agreements on climate protection and political declarations of intent, global greenhouse gas emissions have not decreased. On the contrary, they continue to increase. With a growing world population and significant industrialization in emerging markets such as India and China the emission trend reversal necessary to limit global warming seems to be unlikely. Therefore, large-scale methods to artificially slow down global warming are increasingly being discussed. They include proposals to fertilize the oceans, so that stimulated plankton can remove carbon dioxide (CO2) from the atmosphere, or to reduce the Sun's incoming radiation with atmospheric aerosols or mirrors in space, so as to reduce climate warming. All of these approaches can be classified as "climate engineering". "However, the long-term consequences and side effects of these methods have not been adequately studied," says Dr. David Keller from the GEOMAR Helmholtz Centre for Ocean Research Kiel. Together with colleagues the expert in earth system modeling has compared several Climate Engineering methods using a computer model. The results of the study have now been published in the internationally renowned online journal Nature Communications.

Free mobile green apps

Incorporating sound environmental decisions in our daily lives has been made easier with the availability of several green apps for the mobile device. Below is a list of five useful environmental apps that are free and feature discussions and motivators for carbon footprint identification and reduction, climate change, global forest cover, product scoring based upon environmental impact, and environmental actions all aimed at making better choices for sustainable living.

UK unveils world first carbon capture project at gas-fired power station
February 24, 2014 01:46 PM - ClickGreen Staff, ClickGreen

Deputy Prime Minister Nick Clegg and Energy Secretary Ed Davey have announced a ground-breaking deal with Shell which could generate enough clean energy to power half a million homes, and capture 1 million tonnes of CO2 each year.

COLLEGIATE CORNER: Fossil Fuels vs. Renewable Resources
February 24, 2014 01:07 PM - Flavio Avalos, Class of 2015, Wakefield High School, Arlington, VA

Fossil fuels have been the main source of the energy all over the world. They increase the amount of CO2 emissions, and the emission of CO2 is a great cause of global warming in the atmosphere, destroying the atmospheric layers. What can we do to lower the demand of fossil fuels and become more eco friendly with renewable energy resources? The percent of US transportation sector consumption is 95.4% fossil fuels (Article 3), and this shows the reliance of the US on fossil fuels. As the Institute for Energy states, "Fossil Fuels make modern life possible" and that the only reason that our modern society works and the privileges we get are all due to the fact of fossil fuels (Article 3). Need I remind you: fossil fuels are limited and could go out?

Experts develop low-cost solar panels by recycling rare metals
