Energy diversity brings stability.

چکیده
Energy diversity brings stability W hen I pull up to a gas-station pump, I have three choices: regular, premium, or something in between. I make the obvious choice and fill up with the cheapest option (while I wonder who uses those even more expensive fuels). It is the same scenario whether I'm in State College, Pa., or Los Angeles. All across the U.S., we have a transportation infrastructure based almost entirely on one fuel and one source: gasoline and oil. Our energy portfolio for electricity production is only slightly more diverse, with coal and oil providing most of our energy needs. Despite our brush with a national oil crisis in the late 1970s, we still have not gotten serious about alternative and renewable energy. Rather than facing serious energy shortages in the U.S. by developing other options, we simply extended our pull of energy to substantial reserves outside the country and postponed the inevitable decision to face our " addiction to oil ". Current plans to increase drilling in environmentally sensitive areas or exploit new types of fuels, such as coal gasification or mining methane hydrates, miss a more critical point: We must solve our energy needs while addressing climate change. Our situation is not as simple as it was 30 years ago when we exploited additional sources of carbon-based fuels: We must now solve the energy issue and reduce emissions of CO 2 and other greenhouse gases. There seems to be an underlying need in our energy planning for " the answer " —some sort of techno-magical solution that can solve all our energy needs. Such a technology doesn't exist and, barring a miraculous breakthrough in fusion, isn't likely to be developed soon enough. Instead of searching for a single solution, we need to pursue all the little solutions that, when taken together, add up to something more powerful. We need energy diversity. We could stretch our own national reserves of oil, using it as a fuel of choice in remote areas, while building a new infrastructure based on different fuels that match our potential for energy production in other areas. For transportation, I can imagine biodie-sel-and bioethanol-powered cars in the Midwest; hybrid vehicles augmented by solar energy and hydropower on the West Coast; and clean, hydrogen-gas vehicles in our cities. For housing, I envision strict building codes for eco-minded, energy-efficient housing and government-financed energy-conservation fixes. We must also …

Using energy scenarios to explore alternative energy pathways in California
This paper develops and analyzes four energy scenarios for California that are both exploratory and quantitative. The businessas-usual scenario represents a pathway guided by outcomes and expectations emerging from California’s energy crisis. Three alternative scenarios represent contexts where clean energy plays a greater role in California’s energy system: Split Public is driven by local and ...
متن کاملResearch on Social Stability Mechanisms Based on Activation Energy and Gradual Activation Reaction Theory
This paper draws a comparison between social stability and chemical reaction process, and brings forward the concept of “social temperature” and “activation energy of social agent”. It is considered that social temperature turns out to be the macro symptom of social average energy, and its unceasing upclimbing roots in the energy accumulation of “inferiorization” process of social system; that ...
متن کاملPlant diversity controls arthropod biomass and temporal stability.
Understanding the linkages among species diversity, biomass production and stability underlies effective predictions for conservation, agriculture and fisheries. Although these relationships have been well studied for plants and, to a lesser extent, consumers, relationships among plant and consumer diversity, productivity, and temporal stability remain relatively unexplored. We used structural ...
متن کاملN-glycosylation diversity of CBHI
Background: The information on the role of N-glycosylation is limited. Results: The site and structure of N-glycosylation have evident effects on the activity and stability of CBH. Conclusion: N-glycosylation affects the characteristics of CBHI, and also brings a new function to CBHI as a nonenzymatic synergism factor. Significance: Understanding the effects of N-glycosylation is important for ...
متن کاملSelection Relaying at Low Signal to Noise Ratios
Performance of cooperative diversity schemes at Low Signal to Noise Ratios (LSNR) was recently studied by Avestimehr et. al. [1] who emphasized the importance of diversity gain over multiplexing gain at low SNRs. It has also been pointed out that continuous energy transfer to the channel is necessary for achieving the max-flow min-cut bound at LSNR. Motivated by this we propose the use of Selec...
