Renewable Resources The Heroes

Renewable Resources Also called Alternative Energy Provide an alternative to fossil fuels Reduces air pollution and greenhouse gases Most will not run out or are easily replaced

1) Biomass Energy – material from living organisms (Wood, Manure, Grain) Benefits Costs Biofuels Ethanol – fermentation of starches and sugars to produce a type of alcohol to be used as fuel Biodiesel – produced by vegetable oil mixed with petroleum Does not add extra carbon into the atmosphere Biofuel crops (corn, soybeans) take up land that could be used for growing food instead Deforestation and soil erosion from farm land can occur Relatively inefficient

2) Geothermal Energy – hot water and steam heated from the Earth Benefits Costs Use heat to generate electricity Use hot water directly to heat homes and businesses through a network of pipes Much less air pollution than burning fossil fuels Using up groundwater faster than its replaced could lead to a water shortage Drilling deep into Earth to find heat source can lead to unstable areas (earthquakes)

3) Hydropower Energy – using the movement of river water for energy Benefits Costs Dams – blocks a river and uses the force of the water flowing through the dam to convert to electricity Does not pollute the atmosphere Inexpensive to maintain a dam Interrupts the natural flow of a river, therefore changes the natural ecosystem Can cause land erosion and loss of nutrients downstream

4) Solar Energy – using sun’s energy to generate electricity Benefits Costs Passive Heating – using the sun’s energy naturally Active Heating – using technology, like solar panels, to collect energy and distribute it Does not pollute air or water Limitless supply from the sun Current technology is expensive Solar farms take up land and change natural habitats Dependent on weather – areas that are often cloudy/rainy would find it difficult to use solar

5) Wind Power – converting wind’s kinetic energy into electrical energy Benefits Costs Wind Turbine (windmill) – wind blowing turns the blades to be converted into electricity Does not pollution Can be highly efficient Makes 23 times more than it uses No ability to control the wind and it can be unpredictable Isolated to only places with lots of wind Blades can kill migrating birds and bats

6) Hydrogen Fuel – fuel from the breakdown of water and other compounds Benefits Costs Electrolysis – breaking down water 2H20 -> 2H2 + O2 Does not give off pollution Hydrogen is most abundant element in the universe – it will not run out Hydrogen gas is unstable and can catch fire/explode Current technology this fuel is difficult to produce

Poster Activity JEA, or Jacksonville Electric Authority, is the eighth largest community owned electric company in the country. Because it is community owned, that means JEA is overseen by a board of the directors comprised of community members and by the local government. This allows JEA to make decisions based on the needs of Jacksonville residents. Currently, most of JEA’s power comes from Natural Gas and Coal. However, the JEA board of directors knows that our fossil fuel reserves are going to run out and they are aware that our fossil fuel use is harming the environment; therefore, JEA wants to move toward using renewable energy.
