Off the grid.

  1. 1. Off The Grid. By Nikki Dwyer J.T. Oldham.
  2. 2. <ul><li>In 2008 the average annual electricity for a U.S. customer is 920 kilowatt-hours per month. </li></ul><ul><li>The average price per kilowatt-hour is about $0.11 in Massachusetts. </li></ul><ul><li>The average electricity consumption is 11,040 kilowatt-hours. </li></ul><ul><li>The average price yearly is $1,214.40! </li></ul><ul><li>That’s from some unhealthy resources like coal and petroleum which are very expensive! </li></ul>
  3. 4. <ul><li>Heat Pumps. </li></ul><ul><li>Central Air. </li></ul><ul><li>Water Heater. </li></ul><ul><li>Clothes Drier. </li></ul><ul><li>Water Pump. </li></ul>
  4. 5. <ul><li>Some alternative energy solutions are geothermal energy, solar energy, wind energy and hydroelectric energy. </li></ul><ul><li>These sources can be expensive upfront because you need to drill holes and build windmills, but in the long run you can save an enormous amount of money. </li></ul>
  5. 6. <ul><li>Geothermal energy is becoming a very popular alternative source for energy. </li></ul><ul><li>It’s a very clean and sustainable source of energy. </li></ul><ul><li>Geothermal heat is obtained from internal heat in the earth and then is used to generate steam to run a turbine and then you have electricity. </li></ul>
  6. 8. <ul><li>First of all you must drill a hole into the earth at most three miles and sometimes the heat is exchanged for the air in your house and that’s how it is heated. </li></ul><ul><li>It’s also very capable of generating plenty of energy. </li></ul>
  7. 9. <ul><li>Geothermal energy has many pros such as low emissions, it is renewable, its very clean, it will save you plenty of money and the plants are inexpensive to operate. </li></ul><ul><li>However, a few cons to consider are that it is only available at some parts of the earth, initial drilling costs are expensive and there tends to be some unpredictability with sites. </li></ul>
  8. 10. <ul><li>The cost of drilling a hole could cost anywhere from $10,000 to $30,000. </li></ul><ul><li>An average home would use a three-ton geothermal energy/heat pump system costs roughly $7,500. </li></ul><ul><li>The price is $0.04 for a kilowatt hour. </li></ul><ul><li>Over time it becomes a very inexpensive and smart choice. </li></ul><ul><li>Utility costs become considerably lower. </li></ul>
  9. 11. <ul><li>It would be beneficial for modern and newly built homes to use geothermal energy. </li></ul><ul><li>Appliances would be much less likely to use so much energy, and therefore money would be saved. </li></ul>
