Looks at how replacing desktops with thin clients can save money and power for an organization. The post builds its case using step by step comparison of the computing resources usage scenarios and how these would layout in a thin client deployment versus a desktop deployment of a 5,000 workstation scenario.
This post reports on the newly announced loan guarantees for the concentrated solar power (CSP) Crescent Dunes Solar Energy Project that is to be built in Nevada. This kind of solar power, because it is paired with a molten salt thermal energy storage capacity has the ability to be a load following generation source that is somewhat insulated from intermittency issues as well. For large concentrated solar thermal energy this decoupling of the energy collection from electricity generation makes a lot of sense, because the molten salt is already being used as the working fluid that captures the sun’s heat.
Forecasting what the Earth’s climate might look like a century from now has long presented a huge challenge to climate scientists. But better understanding of the climate system, improved observations of the current climate, and rapidly improving computing power are slowly leading to more reliable methods.
In a troubling development for proponents of geologic carbon sequestration a Saskatchewan farmer has just made public an independent study that links high levels of CO2 found in their farm’s soil to the thousands of tons of CO2 that is currently being pumped into deep oil bearing deposits under their land by Canadian Energy giant Cenovus.
What is the meaning and importance of embodied energy as a measure of sustainability and why we need to develop widely accepted standards for embodied energy? This article explores this somewhat arcane concept that seeks to measure how much energy is “embodied” in a product or service; in other words how much energy is used throughout the entire life cycle of the thing being measured including the energy required by decommissioning, disassembly and deconstruction.
Algae Biofuels – Not Sustainable (Another Response to “Could Algae be the New Corn?” by Julia Verdi)
Last week, Frank Ciampa, posted Algal Biodiesel: Pros and Cons, his response to Could Algae be the New Corn?, written by Julia Verdi. This week, Eamon Keane, responds to Julia’s post, explaining why he does not feel that algae biofuels is a good alternative to oil.
Studies show that corn based ethanol may nearly double greenhouse gas emissions instead of reducing them. Does Algae pose the same risks as corn? Are biofuels the wrong way to go when it comes to identifying fuel sources?
Amid a growing call for reducing atmospheric concentrations of CO2 to 350 parts per million, a group of economists maintains that striving to meet that target is a smart investment — and the best insurance policy humanity could buy.
The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe? by David Biello, Editor of Scientific […]
