3. Timeline

4.  Hydropower accounts for about 7% of our country’s energy production  Hydropower makes up about 52% of all renewable energy production  There is definitely room to improve those numbers, but building the support to make it happen has been challenging How Hydropower Meets Our Energy Needs

5.  Fuel is not burned, so there is minimal pollution  Water to run the power plant is provided free by nature  Hydropower plays a major role in reducing greenhouse gas emissions  Relatively low operations and maintenance costs  The technology is reliable and proven over time  It’s renewable – rainfall renews the water in the reservoir, so the ‘fuel’ is almost always there Advantages of Hydropower http://water.usgs.gov/edu/wuhy.html

6.  High investment costs  Dependent on precipitation  In some cases, inundation of land and wildlife habitat  In some cases, loss or modification of fish habitat  Fish entrainment or passage restriction  In some cases, changes in reservoir and stream water quality/flow  In some cases, displacement of local populations Disadvantages of Hydropower http://water.usgs.gov/edu/wuhy.html

7.  How hydropower affects aquatic species  Draught/flood risk  Global warming emissions Current Issues

8.  Not as efficient as possible because of disadvantages  The Hydropower Regulatory Efficiency Act of 2013  The Bureau of Reclamation Small Conduit Hydropower Development and Rural Jobs Act Efficient Use and Current Policies

9.  Department of Energy’s “Hydropower Vision”  NHA’s plans for the next decade  Public Opinion Future of Hydropower
