Remember a fews years ...Our power grid is decrepit. Remember a fews years ago when the northeast had that huge black out? In the near future there will have to be a major investment in updating the infrastructure of the United States. (if there is any actual financial resources available.) Our system will follow a German model, which has the highest rate of solar energy production of any country in the world. The German government recognizes they have to invest in an updated power grid that allows for localized energy production. The germans also use different solar energy collectors like concaved mirrors for large scale production. <BR/>With current solar panel technology you can get 5Kwh a day from a solar panel on your roof. In comparison, 1 litre of gasoline contains 10Kwh of power. The most important aspect of solar power technology is getting efficiency rates up from 9% to 12 to 15%. that makes solar panels economically viable. Technological advancements are happening to raise efficiency but they are a few years from mass production.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7417847976778607501.post-5486648692137095132008-08-29T13:54:00.000-05:002008-08-29T13:54:00.000-05:00Hi Mary,To add a little bit of perspective on the ...Hi Mary,<BR/>To add a little bit of perspective on the solar issue:<BR/><BR/>Renewable energy has the potential to reduce the use of natural resources (coal and gas) for power generation, but it's still at a significant capital investment. <BR/> <BR/>While the sun's rays are free, the solar panels to capture and convert that energy into electricity are expensive--even with the Federal Tax Credit (which expires 12/31/08 and is capped at $2,000 for residents) and TVA's Generation Partners program (which currently pays $0.15 per kilowatt hour of solar energy you generate over a 10-year period). <BR/> <BR/>An example of the economics: A 2-kilowatt (kW) solar array will cost between $14,000 and $20,000 installed, based on national averages. That 2-kW system will produce between 2,600 and 2,800 kilowatt hours (kWh) of electricity per year, according to the National Renewable Energy Laboratory's rating of solar resources for the Memphis area. The average MLGW household uses 1,300 per month--so in one year's time, you would generate two month's worth of electricity, for a capital investment of about 20 grand. <BR/> <BR/>While TVA is very interested in anything that reduces the overall load (consumption is growing faster than capacity for them), our best bet right now is to reduce the amount of energy our homes require. Easy, low/no cost options such as thermostat settings, caulking and weatherstripping around doors and windows still represent the best bang for your buck, as do capital investment choices such as replacing your air conditioner with an energy-efficient model of 14 SEER or above. I replaced my old warhorse central AC unit last year and it's made a big difference in our summer bills. <BR/> <BR/>MLGW offers two renewable energy programs administered by TVA, the federal power authority that supplies electricity for MLGW and 158 other utilities in our region. For further information on TVA's Generation Partners solar generation program or TVA's Green Power Switch voluntary pricing program, contact MLGW at greenpowerswitch@mlgw.org. Also, our blog at www.mlgw.blogspot.com often contains green and energy conservation info. <BR/><BR/>Thanks for weighing in with you interest -- energy efficiency is becoming more essential for all of us as residents.<BR/><BR/>Glen Thomas,<BR/>Supervisor, Communications & PR<BR/>MLGWmlgwglenhttps://www.blogger.com/profile/03705672355492390998noreply@blogger.comtag:blogger.com,1999:blog-7417847976778607501.post-1967143062499604512008-08-29T12:43:00.000-05:002008-08-29T12:43:00.000-05:00I think it depends on how long you plan to live in...I think it depends on how long you plan to live in your house. <BR/><BR/>On the other hand, I doubt MLGW sees it's in its best interest to help regular people generate their own energy.<BR/><BR/>I heard a story recently from a couple who want to put solar panels on their house. While out somewhere, they saw an MLGW rep who was wearing a button that said, "Ask me about solar energy" or something to that effect. <BR/><BR/>So they did. And the guy said something like, oh, I can't help you with that. I'm talking to people about the green power switch.marycashhttps://www.blogger.com/profile/11723540914036793887noreply@blogger.comtag:blogger.com,1999:blog-7417847976778607501.post-53612604688220321292008-08-29T11:47:00.000-05:002008-08-29T11:47:00.000-05:00$24000 over a thirty-year mortgage vs. $1800 a yea...$24000 over a thirty-year mortgage vs. $1800 a year MLGW bill sounds like a pretty good deal to me over the long term.fancycwabshttps://www.blogger.com/profile/14522689806577600647noreply@blogger.com
