Biocombustibles de primera generación: ¿Buenos o malos para el hombre y la biósfera? (1)

Los autores de este estudio concluyen que “bajo los actuales sistemas de producción, el efecto negativo de los imoactos de la producción de biocombustibles sobre la depleción del fósforo parece exceder a los impactos positivos sobre la mitigación del cambio climático.” Y, agregan, “los actuales objetivos para biocombustibles” – que dicen que solamente pueden alcanzarse con fuentes de biocombustibles de primera generación, como ha sido descrito por la Agencia Internacional de Energía (2008) – “afectará la seguridad alimentaria futura y puede tener un impacto neto negativo[...]

La optimización térmica de todos los ecosistemas (1)

Si por cualquier motivo el mundo comenzara a calentarse nuevamente, es muy probable que la mayor parte de la vasta variedad de ecosistemas se convertirían en más productivos de lo que lo son hoy en día.

Pueden los focos ahorradores dañar la piel?

Un nuevo estudio indica que los focos ahorradores pueden dañarse y producir daños en la piel. Can Compact Fluorescent Lightbulbs Damage Skin? A new study suggests that certain types of the energy-saving lightbulbs can become damaged and then may hurt skin cells By Umair Irfan and ClimateWire  | July 25, 2012 The curlicue compact fluorescent lamps (CFLs) oft touted as an Earth-friendly alternative to standard incandescent bulbs may cause skin damage, according to a new study by researchers at Stony Brook University. The bulbs are already known to pose hazards from using mercury, a toxic element,[...]

Time to terminate Big Wind subsidies

The time has come to terminate Big Wind subsidies and protect environmental values, endangered species, jobs and human welfare. by Paul Driessen Unprecedented! As bills to extend seemingly perpetual wind energy subsidies were again introduced by industry lobbyists late last year, taxpayers finally decided they’d had enough. Informed and inspired by a loose but growing national coalition of groups opposed to more giveaways with no scientifically proven net benefits, thousands of citizens called their senators and representatives – and rounded up enough Nay votes to run four different bills[...]

UN Fails to Finalise Rio+20 Plan

After two weeks of closed door negotiations, a U.N. preparatory committee has failed to reach consensus on a global plan of action, titled “The Future We Want,” to be adopted by a summit meeting of world leaders mid-June in Brazil. In an effort to break the deadlock, the PrepCom will give another shot at the zero draft when it holds an unscheduled five-day session beginning May 29. This will be a last ditch attempt to finalise the draft action plan. –Thalif Deen, IPS News, 7 May 2012 Representatives from governments negotiating the outcome document for the United Nations Sustainable[...]

Why Obama is Absurd to Suggest Algae

by Newt Gingrich It’s true that research labs are experimenting with algae-based biofuels, and we wish them well. If someday in the future, we’re all driving cars based on inexpensive fuel from algae, it’s possible that would be a positive development. But there’s a big difference between that and offering algae today as an answer to high gas prices, or using taxpayer money to subsidize this particular technology — such as the $14 million grant the administration gave an algae experimenter, or the tens of millions of dollars in loan guarantees the Department of Agriculture[...]

Who Are the Environmentalist Extremists?  by Marita Noon on March 19, 2012

Second of a three-part series of excerpts from Energy Freedom by Marita Noon Originally published in the Washington Examiner Part 1, “Big Green Wants To Repeal the Industrial Revolution,” is available here. So who are all these evil-appearing “environmentalists?” Should all Birkenstock wearers be suspect? What about the lady at the grocery store with the canvas sack for her purchases? There is a difference between those of us who care for the earth, want to use it wisely, and believe in recycling—and those who are in decision-making positions, setting policy and/or funding the programs.[...]

Big Green Wants To Repeal the Industrial Revolution  by Marita Noon on March 15, 2012

First of a three-part series of excerpts from Energy Freedom by Marita Noon Originally published in the Washington Examiner Environmentalists would have everyone believe that oil, gas, and coal—all fossil fuels—are at the base of much of the world’s ills. Nuclear is no better. They even oppose hydropower, wind energy, and commercial solar. Yet, they claim the high ground and position themselves as the moral authority. What would the world look like if they were setting truly setting energy policy rather than merely influencing it? An in-depth study of environmental groups’ energy-related[...]

US: Charles Manson energy

by Paul Driessen     “… gleaming white wind turbines generating carbon-free electricity carpet chaparral-covered ridges and march down into valleys of Joshua trees.” This is “the future” of American energy – not “the oil rigs planted helter-skelter in [nearby] citrus groves,” nor the “smoggy San Joaquin Valley” a few miles away.The Forbes article’s poetic paean to Aeolian energy nevertheless voiced consternation that a 300-megawatt “green” turbine project might kill some of the magnificent California condors that are just coming back from the edge of extinction –[...]
