Paige DeWitt-Holub 02/15 Energy – Group Discussion – and in groups -“40% of the energy used is for electricity, 30% for trains and automobiles, 21% industrial, ~9% personal home use.” 1 -coal, nuclear, then natural gas, the renewables (lowest factor of energy produced) -coal power plants (C, aerosols) -ecological consequences, European Union coal problem might even parallel America’s problems -the alternatives to “dirty” energy Group talk (10-15 minutes) weigh the costs, benefits, opinions… “1. Coal/Petroleum +’s Cheap, Abundant, Reliable, Economy, semi-reliable Jobs, old and reliable technology/factories -‘s detrimental to health (aerosol byproducts cause nerve and brain damage, cancer), cities are ruined with a mono-industry, emissions are dirty and so are coal mines but there are initiatives to clean-up destroyed land --consensus is that coal is a problem 2. Hydro/Hydro-Electric Dams -+’s relatively efficient and simple river/water technology, zero emissions (clean?), recreation/tourism -‘s high maintenance for concrete and power converters, kills fish, wildlife relocation, scale, limited lifetime, can fail occasionally (India), existence of dam is altered forever (sediments are trapped), water paths changed forever, recreation/tourism, limited areas and limited number that can be built = poor investment, major off-shore current (Australia) 3. Nuclear/Nuclear Fission -+’s/-‘s cleaner when it goes right?, power, war (Uranium)-‘s risk/failures are immensely dangerous, nuclear by-products are hard to maintain and stabilize, thermal pollution, finite, expensive to invest, Uranium mines are less environmentally unsound than coal mining, war 4. Natural gas +’s abundant, no refinement (methane, etc.), burns clean, $ source independently -‘s expensive and factory systems plus infrastructure pipelines of carrying the gas, transporting via truck as well (explosive), natural gas wells need methane, hydrocarbons, water intensive 5. Wind +’s multi-use, clean/ 0 inputs 1 All quoted pieces were taken from the words of Professor or Cody. -‘s requires a lot of land area (about 30% to run the whole world), high maintenance, inefficient conversion of energy, habitat (large wind farms in migration pathways of animals of flight causing death – cause more maintenance? Cost deterring from investing in land would make less land realistically available to this form of technology), large/ugly? 6. Solar +’s small-scale benefits, clean, mobile -‘s expensive to install, sun necessary, 7. Geo-thermal +’s clean -‘s locational 8. Agro-Fuel +’s could use spoiled/wasting food -‘s locational“ Paige DeWitt-Holub 2/17 -infrastructure lasting is based on investments, “infrastructure inertia” requires a lot of planning to deal with -energy needs to be created with less detrimental or excessive energy – efficiency is certainly more sustainable in relationship to raw materials GUEST SPEAKER: Topic: “The Politics of Fracking, Isaac Rivera, Department of Geography and Environmental Science, Isaac.email@example.com” -locality of fracking, as well as the global contentions between this -resumed after an informational video about the system of fracking based in hydrologic fracking, risks associated with green house gasses and other chemical by-products -already the film is outdated in terms of the facts -the price to utilize the energy of natural gas is rising faster than people can produce documentaries for -politics of fracking, reservations (fracking leakage appropriateness) -Harvard research project states 30-60% of natural gas comes from the U.S. – Dakotas, mid-areas -by-product water is arguably unsound, “spills” are considered unnatural and unsound, methane found in water -natural disasters, and in particular, earthquakes have raised concern about the safety of wells, wells could cause fault lines in the earth to become faulty (debatable) -Profit (more business $) -Groups of people where locational problems might become a state issue when maybe it should be a federal issue -mean average temperature: Copenhagen Climate Talk (’08) last year brought this temperature down one percentage in Celsius -OPEC = tries to keep oil functions at an importing standard to the U.S. from exports in the Middle East, all about prices within creating a demand for fuel in the America market ---------------- TPP , Trans-Pacific Partnership – desire for the U.S. to expand the markets -EPA. Movie: Gasland -about Methane in the water that cannot be treated with typical water purification problems, thus making water immensely flammable and toxic – Pennsylvania -debates are initiated in a manner in which something is politically on the table but perhaps is not in other spheres of the scientific framework/societal consciousness -> media is the olive branch of many different lobbyists on all levels -is fracking sustainable and able to be safely repurposed without contributing to negative increases in climate change, etc. ----> similar to petroleum oil spills that cannot be solved with ease by modern technological advances, as it appears that perhaps we, as citizens, will have to decide how we want to counteract all the injustices that the environment faces at the hands of energy for societies -economics of how to alter the the reliability first, on an international, particularly European level -societal and/or physical – “synthesis” experiment done at UMaryland -similar to incidents in Commerce City – spill located, N. Denver, spill located again at S. Platte River -Locke’s theory of property and the evolution to modern-day understandings of value, circumstance, etc. -oil and gas found in a property? Alters the rights of residential prices in favor of mineral rights - mineral rights can make the land with raw materials be expeditiously drilled by the govt. under the land but not over/on your land -ranch land, etc. because Colorado is a very divided state -not many companies, so how much is relegated to watchful control? How do you ban what the state government wants for the benefits? -“Tragedy of the Commons” – individual benefit – risks are everywhere -efficiency (a question of changing the form of energy to something less negatively impactful) and tax breaks/cuts – politicized, might still be going to non-renewable energies -thinking of the consequences still does not result in complete and non- debatable policies -- democratic system -Sharon Steinburg - NYS
