* Alternative Energy Summary + Renewable Energy Sources in the U.S.
 * __ REVIEW SHEET ON ENERGY __**

__TERMS__:

*Active Solar energy and examples – uses a device, such as a pump or fan, to transport the energy collected from the sun.

+Biomass energy and examples – Any organic materials that can be burned and used as a source of fuel. Ex. Farm waste such as cow manure is processed into biomass to form biogas.

Bioreactor (NOVA)–

*Conduction – the transfer of thermal energy between regions of matter due to a temperature gradient(the speed and change of temperature).

*Convection – the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.

*Energy – any source of usable power, as fossil fuel, electricity, or solar radiation.

*Fish Ladders – series of pools arranged like ascending steps; allow migrating fish to swim upstream around a dam

Fossil Fuels and examples –

Fuel cells and applications (NOVA) –

+*Gasohol – gas extender; fuel that typically consists of 90% gas and 10% ethanol (fermented agricultural crops and crop wastes)

*Kinetic energy and examples – the energy of a body or a system with respect to the motion of the body or of the particles in the system.

Magma –

*Nacelle – an enclosed compartment that houses a gearbox and generator as well as the machinery that controls the turbine.

NIMBY –

+Nonrenewable energy and examples – energy that cannot be replenished; includes petroleum, coal, oil, and natural gas (fossil fuels)

*Passive Solar energy and examples – absorbs and stores energy from the sun and then slowly releases heat without using pumps or fans to distribute the heat

*Potential energy and examples – is energy at rest - it’s stored energy

+Renewable energy and examples – energy that is continually replenished; comes from natural resources such as flowing water, sunlight, wind, and geothermal heat

Solar paint (NOVA)–

*Solar panels for heating –

__CONCEPTS__:

*Photovoltaic cells and their design (NOVA)

*First and Second Laws of Thermodynamics

__2nd__ -

Design a building to maximize renewable energy sources and minimize costs (//Soaking Up the Sun Article//)

Explain how a turbine works to produce electricity

*Describe ways to implement energy conservation

__ Describe the **potential applications, advantages, disadvantages, and how the following five are produced**: __

+*__Solar energy__ –

+*__Hydroelectric energy__ – Hydroelectric energy is produced by force of water. Specifically, the electricity is generated as moving water turns a turbine. One **advantage** of hydroelectric power is that its production releases no pollutants.

A **disadvantage** is that hydroelectric power does produce thermal pollution; in addition, it requires that rivers are dammed, and this can change the rates at which rivers flow and also lead to the destruction of habitats. On the other hand, as water is held behind dams, new habitats, in the form of wetlands, are created. > also lead to the destruction of habitats. > the salmon from returning to their hatching streams.
 * **Disadvantage for dams**-
 * can change the rates at which rivers flow and
 * Sediment from the dams add additional weight on the structure and means that dams have to be built strong enough to hold back the many tons of sediment. Another problem is that fish that spawn in the normally silty river no longer have a place to do so.
