What is Hydropower? • Hydropower is energy that comes from the force of flowing water. • Hydropower is referred to as a renewable energy source because water on Earth is continuously restored through precipitation. • As long as the water cycle continues we will never run out of Hydropower. • Hydropower currently provides 96% of the United States renewable energy.
Importance • Hydropower currently supplies about 10% of the United States electricity, but it has supplied much more • In the 1920’s hydroelectric power supplied near 40 % • True importance lies with its ability to respond quickly in times of need. • Hydropower can be started and shutdown instantly to go for immediate demands
Challenges and Barriers • Site Specific impacts on local ecosystems and surrounding committees • Environmental and regulatory issues • Timing and development of ways to transport the power • Hydropower is often feasible in remote locations • Transport is difficult, and in order to do so efficiently the power must follow the process below
Policy • Currently the constraints on hydroelectric development stem from but aren’t limited too these main issues: technical, environmental, financial, and tariff related Some examples of this policy include… • The Hydroreform pointed out these acts as being very influential in hydroelectric power • Feed In Tariffs • EPAct • Green Pricing Programs
Hoover Dam • Construction started in 1931 and was completed in 1936 • Built along the Colorado River • Designed for power generation, agricultural purposes, and to prevent flooding • Dam formed Lake Mead which is the largest water reservoir in the United States
Hoover Dam (Cont…) • Hoover Dam generates about 4 billions kilowatt-hours of hydroelectric power which is enough to provide for about 1.3 million people in Nevada, Arizona, and California • Was largest hydroelectric installation but still remains one of the countries largest • Provides energy to many people with no associated greenhouse gases and allows Colorado River to be controlled, which helps provide local farmers with a regular supply of water
Wind Energy • Wind Turbines convert wind in to electricity • Use of wind power is growing every year • Provide electricity through out the world
Wind Energy Statistics • World Wind Power Capacity: 190,000 MW • U.S. Wind Power Capacity: 43,000 MW • States with Utility-Scale wind turbines: 38 • Most productive state: Texas 10,000 MW • Ohio: 27th with 67 MW
Wind Energy Policies • Tax Credit: 2.2 cents/kilowatt-hour • Renewable Electricity Standard • Ohio: 25% by 2025 • Transmission Policies • Federal Energy Regulatory Commission passed Order 1000 • Siting Policies • U.S. Fish & Wildlife Service
Fowler Ridge Wind Farm • Located in NW Indiana in Benton County • Owned and operated by both BP Alternative Energy North America and Dominion Resources with each owning a 50% stake in it • Being built in three phases • Phase 1- constructed from 2008 to 2009 and can produce 400 MW of power • Phase 2- constructed from 2009-2010 and can produced 200 MW of power • Phase 3- is expected to begin soon and will produce 150 MW of power
Fowler Ridge Wind Farm (Cont…) • 460 turbines with a capacity of 600 MW • Can power about 200,000 average American households • Along with other projects has led to Indiana to be ranked as one of the top three fastest growing states in generating wind power by the American Wind Energy Association • Spread over 50,000 acres of land it is one of the largest wind farms in the world
Solar Energy • Passive Solar Energy • Active Thermal Energy • Solar PV
Passive Solar Energy • Simplest form of Solar Heating • Used for Centuries • South Facing Windows • Overhangs on Windows
Solar Thermal Systems • Power Generation – Trough System, Heliostat • High Heat Produced • Home Water Heating – Evacuated Tubes, Flat-Plate, Non-Glazed Collectors • Medium to low heat produced
Solar Photovoltaic • Monocrystalline Silicon – One large Crystal • Polycrystalline Silicon – Thousands of Compressed Crystals • Thin Film
SEGS • Located in California’s Mojave Desert • Consists of several solar plants constructed from 1984 to 1991 • Newer plants are more technologically advanced and cheaper at providing electricity • Designed to supply power during peak demand periods • Specifically hot summer afternoons because power usage is high and so is plant production
SEGS (Cont…) • Largest solar energy facility in the world with capacity of 354 MW • During peak production it can power 230,000 homes • Offsets an estimated 3,800 tons of pollutants that would have been produced • Covers more than 1,500 acres in the desert with more that 900,000 mirrors that convert the sunlight to energy we can use • Can still work on cloudy days because the plant has a supplementary gas boiler which can heat water the generate electricity through steam
Beginnings of Alternative Energy Legislation • Clean Air Act of 1970 • Called for a reduction in mobile pollutants • Alternative Motor Fuels Act • Established the use of CAFE Credits • Corporate Average Fuel Economy • Aimed to improve average fuel economy of cars and light vehicles.
Energy Policy Act 1992 • Energy Policy Act 1992 • Imposed regulations and requirements for state, federal and alternative fuel providers to develop more energy efficient vehicles • Amended several times over the years • Also included provisions on wind, biomass, geothermal , hydropower energy. • Energy Policy Act of 2005 • Expanded focus on the development and growth of the alternative fuel sector • Focused on developing an infrastructure
Extensions • Incentive programs for alternative energy have continually been extended from the Energy Policy Act of 1992. • Extensions on alternative energy, in particular wind production tax incentives, are currently being considered by the Ways and Means Committee (2016)
Energy Independence and Security Act of 2007 and 2008 • Aimed to increase alternative energy sources and raise CAFE standards • Provides tax credits and exemptions for alternative energy and more efficient technologies.
American Recovery and Reinvestment Act of 2009 • Allocated $800 billion for investment and development of alternative energies • Intended to move the U.S. towards energy independence. • $2.5 million designated for research, development, and implementation of energy efficiency and renewable energies.
State Level Initiatives • E.X. SREC Trade • Solar Renewable Energy Certificates • Creates an incentive to purchase solar energy • Requires providers to purchase a certain amount of their energy from solar generators • SREC Markets • Ohio market • In-state, outof state systems • 50% of SRECs must be generated from in-state sources
Goals and concerns for the future • Security of supply: make sure enough energy is available • Limit carbon emissions to slow global warming • High energy prices could affect economic development Source: http://sapiens.revues.org
Advances in alternative energy • Photovoltaic systems are increasing in cost-effectiveness with “thin film” technology • Geo-exchange systems (ground source heat pumps) can save on home heating costs • DOE renewable energy lab created a website with a nationwide list of alternative vehicle fueling stations • Source: www.nrel.gov
New energy technologies? • Combining 2 energy sources • Solar-electric watercraft • Airborne wind farms • Source: www.alternative-energy-news.info
Other possible technologies • Algae as biofuel • Solar wind power • Robots to clean up oil spills • Source: www.alternative-energy-news.info
100% of energy could be renewable • Some scientists believe 100% of energy on earth could be renewable by 2030 • Wind and solar energy that is available is much more than energy consumed • 3.8 million wind turbines, 90,000 solar plants, more geothermal and tidal energy • Cost of power would be less than for fossil fuels and nuclear power • Lack of political will is a major obstacle • Source: www.scientificamerican.com
