Document Summary
Non-hydro renewables - wind, solar, geothermal, tidal, biomass/biofuels. Collected solar energy concentrated in order to produce steam for driving turbines and generating electricity. Needs lots of water to clean mirrors, and also to cool main system. High setting up cost but lower when combined with natural gas turbine backup. To be cost effective, wind and solar depend on high quality resources and. Wind in midwest, mountains (high elevation), east coast. Wind and solar are difficult to store. Renewable portfolio standards are specified min share of electricity. What are the basics designs and components of hydropower systems. Water - hence is limited to specific places (reservoir or river system) Power house (turbines > generators > transformers ) Transmission lines - often source areas are far away from electricity consumption areas. Most suitable for fluctuating for fluctuating weather patterns. Longer penstock passes water through a series of turbines. Downside is affected by fluctuations in weather (river can go down) can"t be regulated.
