When You Start with a Faulty Assumption, You End Up with a Faulty Conclusion: The Problem with an Anti-Cellulosic Ethanol Study
This weekend, the Associated Press published its coverage of the results of a recent University of Nebraska study that wrongly concluded that cellulosic ethanol from corn residue (like stover) could result in 7% more greenhouse gas emissions than gasoline in the short term. The study was conducted under conditions that are entirely inapplicable to modern cellulosic ethanol production, rendering its findings meaningless. Renewable fuel experts and agricultural scientists alike have slammed the study’s methodology and the EPA also distanced itself from its findings - with good reason.
With Washington adrift and the United Nations climate change panel again calling for action, the search for new clean energy finance solutions continues.
Renewable energy. The very concept itself is undeniably awesome. So awesome, in fact, that sometimes we can’t help but proclaim our love for renewables. Luckily, Earth Day is fast approaching, April 22, so this seems like an appropriate time for us to proclaim our enthusiasm for clean energy.
This is the second piece of a two part series. The first post is here.
Smart grids are being introduced in certain military installations, such as in Washington, DC and San Diego, CA, but are not yet fully operational. They are impressive but the big question remains – are they vulnerable to cyber-threats? In-the-field applications experimentation and training for applications-oriented “real world” sites is laudable, but the learning curve takes time on optimizing energy savings and generation, load shifting and shedding, sensor coordination, and maintenance. The first DoD step should be a DoD-wide requirement that all on-site energy systems connected to the electric grid must minimally have “smart” switching. This requirement must become a standard practice; meaning when there is independent on-base electric generation, if the grid goes down, the electric power is redirected towards critical functions. This can be accomplished automatically and not via computer or internet so there can be no cyber-interference.
