European study shows biofuel production can increase with low impacts
January 16, 2015 07:07 AM - EurActiv
EU countries could increase their production of biofuels with a minimum impact on the environment, Utrecht University scientists concluded in a study published on Tuesday (13 January).
Biofuels are the main green alternative to fossil fuels used in transport, but they compete with feed crops that share the same agricultural land.
As a consequence, forests are being turned into farmland to increase the terrestrial surface for planting more food crops, a phenomenon known as indirect land use change (ILUC).
Britain brings back the battery-powered train
January 13, 2015 08:14 AM - ClickGreen Staff, ClickGreen
The first battery-powered train to run on Britain’s rail network in more than half a century is to enter passenger service this week. The pioneering engine marks an important milestone in the project to demonstrate the viability of an eco-friendly battery-powered train for the twenty-first century.
Denmark Sets New Wind Power World Record
January 9, 2015 08:47 AM - Leon Kaye , Triple Pundit
Denmark has long been one of the world’s leaders in wind power. The country of 5.6 million has set a goal of generating 50 percent of its power from clean energy sources by 2020 and aims to be entirely fossil fuel-free by 2050. Those goals, especially the one for 2020, are well achievable: Denmark has announced it scored 39.1 percent of its energy from wind in 2014.
Carbon capture and the UN Economic Commission for Europe
January 9, 2015 07:32 AM - EurActiv
The only way to limit global warming to less than two degrees is to combine renewable energy and energy efficiency with a large expansion in the use of carbon capture and storage, writes Christian Friis Bach. Christian Friis Bach is executive secretary and under-secretary-general of UN Economic Commission for Europe (UNECE).
I will admit that just a few years back I was very sceptical. Today I am convinced that we must do it. We must capture the carbon dioxide emitted from burning fossil fuels.
Oil prices tumble. Coal resources are vast. Large new gas reserves have been found. Fossil fuels will be with us for many decades and will continue to underpin social and economic development around the world. We need to invest heavily in energy efficiency and in renewable energy sources, but the only way we can hope to limit global warming to less than two degrees is to combine it with a significant expansion of the use of carbon capture and storage (CCS).
Which fossil fuels must remain in the ground to limit global warming?
January 8, 2015 08:58 AM - University College London
A third of oil reserves, half of gas reserves and over 80% of current coal reserves globally should remain in the ground and not be used before 2050 if global warming is to stay below the 2°C target agreed by policy makers, according to new research by the UCL Institute for Sustainable Resources. The study funded by the UK Energy Research Centre and published in Nature today, also identifies the geographic location of existing reserves that should remain unused and so sets out the regions that stand to lose most from achieving the 2°C goal.
Wave Energy looks very favorable from a cost standpoint
January 8, 2015 06:59 AM - Ted Brekken, Oregon State University
A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power.
The findings, published in the journal Renewable Energy, confirm what scientists have expected – that wave energy will have fewer problems with variability than some energy sources and that by balancing wave energy production over a larger geographic area, the variability can be even further reduced.
Renewables Dominate New US Electrical Generating Capacity
December 24, 2014 10:01 AM - Clean Techies Staff, Clean Techies
According to the latest “Energy Infrastructure Update” report from the Federal Energy Regulatory Commission’s (FERC) Office of Energy Projects, wind energy and solar power combined provided over 70 percent (71.82%) of the 873 megawatts (MW) of new U.S. electrical generating capacity placed into service in November 2014. Specifically, three wind farms came on line last month, accounting for 333-MW of new generation in service. These included Stella Wind Farm’s 182-MW Panhandle Wind Farm Phase II expansion in Texas and the 150-MW Origin Wind Energy project in Oklahoma. New wind generating capacity this year thus far has more than doubled that for the same period in 2013 (2,525-MW vs. 1,112-MW).
Study finds reefs reduce wave energy by 97%
December 18, 2014 08:50 AM - Brendan Bane, MONGABAY.COM
We have a lot of stake in the coast. Coastal waters are where we host fisheries, build homes and turn to for tourism and recreation. So how should coastal communities, which comprise nearly 40 percent of the world's population, safeguard against flooding, erosion and violent weather? Marine scientist Michael Beck suggests the solution is growing right beneath some waves and, in many cases, it has been waiting there for thousands of years.
New York fracking ban has broader implications for America
December 18, 2014 06:48 AM - Center for Biological Diversity
After years of public pressure, New York today became the second state to ban hydraulic fracturing because of risks to people and the environment. The announcement from Gov. Andrew Cuomo adds to the pressure on the Obama administration to end fracking across the country, including on America’s public lands.
“New York just took a huge leap forward in protecting its people and wildlife from the dangers of fracking,” said Kassie Siegel of the Center for Biological Diversity. “Now it’s time for other leaders to follow, including President Obama and Gov. Jerry Brown in California.”
New process turns biomass 'waste' into chemical products
December 17, 2014 03:13 PM - Elizabeth K. Gardner, Purdue University
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets. A team of researchers from Purdue University's Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities. Lignin is a tough and highly complex molecule that gives the plant cell wall its rigid structure.
