I have enormous respect for the Energy Committee Chairman his account should be defeated but unfortunately circuit and solid the following five reasons.
First, energy efficiency is standard (RPS) in many State renewable portfolio and include clean energy standards (CES), and it should be. Amory Lovin applicable have been many substantive reports that show it is always cheaper and compensate for cleaner production, the word "Negawatts" old-fashioned and analytical groups such as ACEEE as energy. Perform the same task with less energy (and water) should be a national priority and a priority objective of the energy policy of the Federal and local government.
If we were to compete in the global market, we never equivalent with the developing countries work prices and material inputs were now global are - only better processes and lower inputs (energy and water) our U.S. can improve competitive advantage and it is time we take it seriously.
Secondly, the portfolio of renewable energy sources is next cleanest option if sustained. Of water and air pollution, waste and greenhouse gas emissions: geothermal energy, marine (Freeflow tidal, hydropower, ocean currents, waves and thermal), solar (daylight, concentration, solar energy, photovoltaic and solar thermal), wind and heat (heat and power, CHP) are essentially emission-free and low-or no water have. Geothermal energy and CSP are heat engines (Brayton, Organic Rankine cycle and Stirling), thermal energy, power use without to make water as well as more recent approaches use less water than standard power plants.
Third parties, biomass energy and fuels, based in the ground such as contaminated agricultural wastes, forest disturbances on organic waste, and manure and litter not returned can - are clearly winners as well as the air and water pollution and the benign disposal of waste. Instead of manure in open basin (pigs), litter piles (poultry), or to leave in much manure (cattle) and so that these wastes decrease in methane - a 20 times + more potent greenhouse gas - biomass can a solid winner on all counts.
Fourthly, natural gas is triad, the third leg of energy traditionally in most cases, it is the cleanest fossil fuel, and well integrated into the future renewable and hydrogen economy. I still believe that it can serve this purpose. Ambitious Fracking can however this vision in danger brought. Apart from bans as a result of the earth quake in certain areas of Ohio and Great Britain - the real threat is the copious use of water resources and some of the items also sold study Duke University of Glencore, the 2011 closed "Methane contamination of drinking water accompanying gas wells drilling and hydraulic Division (PDF)" below.
Directional drilling and hydraulic Division increase dramatically natural gas extraction technologies. In aquifer on the Marcellus and Utica of schist formations of Northeastern Pennsylvania and upstate New York, we document systematic evidence of methane contamination of drinking water in shale gas extraction associated.
In August 2012 released EPA its report on whether Glencore had contaminated the ground water or contaminated wells and the Wind River in Wyoming. According to an article on MSNBC.com "EPO stressed that the results are specifically pointed out regarding Pavilion, that the specific type of Fracking used by Glencore methods elsewhere distinguished it in regions with different geological characteristics." "The Fracking occurred below the level of the aquifer water and nearby water wells, said the EPA."
But more seriously can radiation in the Fracking waste. An article published in the March 2011 in the following declared Post-Gazette Pittsburgh:
Wastewater from Marcellus shale drilling can contain unhealthy levels of radioactivity, and federal officials, scientists, industry, and the former head of the Pennsylvania Department of environmental protection, testing of drinking water sources and full disclosure of the results called for have.
The New York Times reported in a story Saturday that 116 of the 179 that had fountains of Marcellus in Pennsylvania high radiation in wastewater samples and sewage were discharges into rivers and streams for radiation not tested, while authorities and industry aware of the risks. The radiation is used by water, to hydraulic fracture that deep, 380 million-year-old slate level and allow the natural gas keeps picked it
Fifth, all of the above faded in comparison to the carcinogens found in coal. In February 2011, who worked environmental integrity project, along with Earth, justice and physicians for social responsibility published a report called "EPA blind spot: hexavalent chromium in the coal ashes." The West Virginia register-Herald, which covered the report, wrote:
Hexavalent chromium can is a well-known congener and very toxic even in small doses. According to the report, which took environmental protection agency, that coal ash bases chrome in great excess of EPA thresholds and chrome, leach almost that of coal ash 100 percent hexavalent chromium…
