Producing electricity with hydropower is the most water-intensive method, owing to evaporation from reservoirs. Nationwide, electricity from hydropower plants consumes about 9 gallons of water per kilowatt-hour (<abbr title="A kilowatt-hour is a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. One kWh is equivalent to 3,412 Btu."><a class="glossary-term" href="http://www2.buildinggreen.com/glossary/6#term2429">kWh</a></abbr>) of electricity produced.</p> <p class="Standard">In some parts of the world, this evaporation is a big problem because of the relative scarcity of water and its use for drinking water. In the arid Southwestern U.S. this evaporation is a huge issue, especially from reservoirs like Lake Mead.</p> <p class="Standard"><strong>Water use for thermoelectric power plants</strong></p> <p><a href="http://www2.buildinggreen.com/blogs/how-much-water-turn-light-bulb" target="_blank">read more</a></p> Energy Solutions Water Wise Guys http://www2.buildinggreen.com/blogs/how-much-water-turn-light-bulb#comments Wed, 16 Apr 2014 16:40:18 +0000 Alex Wilson 18853 at http://www2.buildinggreen.com 6 Ways Our Household is Saving Water—And Energy http://www2.buildinggreen.com/blogs/6-ways-our-household-saving-water-and-energy <div class="field field-type-text field-field-bg-blog-author-name"> <div class="field-label">Author name:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Alex Wilson </div> </div> </div> <div class="field field-type-text field-field-bg-blog-category"> <div class="field-label">Blog Category:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Energy Solutions </div> <div class="field-item even"> GreenSpec Insights </div> </div> </div> <h3 class="Standard">Saving energy isn’t only about using less electricity and fuel; it’s about saving water.</h3> <div><a href="https://www2.buildinggreen.com/sites/buildinggreen.com/files/Blog_Images/Alexs_blog_images/Kohler_Bancroft_showerhead_1614_MedRes.jpg" target="_blank"><img src="https://www2.buildinggreen.com/sites/buildinggreen.com/files/Blog_Images/Alexs_blog_images/Kohler_Bancroft_showerhead_1614_MedRes.jpg" /></a> <strong>Our 1.75 <abbr title="Gallons per minute (gpm) is a measurement of the flow rate of water faucets and fixtures."><a class="glossary-term" href="http://www2.buildinggreen.com/glossary/6#term1854">gpm</a></abbr> Kohler Bancroft showerhead.</strong><br /><em>Photo Credit: Alex Wilson<br /></em></div> <p class="Standard">In this weekly blog, I’ve focused a lot of attention on the energy-saving measures at our new home—from the innovative insulation materials we used to the air-source <abbr title="A type of heating and/or cooling equipment that draws heat into a building from outside and, during the cooling season, ejects heat from the building to the outside.
